+
+Tue Jan 5 09:12:01 UTC 2010 lukem
+
+ * If ARG_MAX isn't defined, use the result from sysconf(_SC_ARG_MAX).
+ Fixes build when using newer glibc.
+
+ * Add libnetbsd.la to the LIBADD for libedit.
+ Fix provided by Adam Sampson.
+
+Mon Jan 4 06:28:07 UTC 2010 lukem
+
+ * Distribute various files not shipped by default automake rules,
+ to use 'make dist' instead of 'cvs export'.
+
+Wed Dec 30 00:12:47 UTC 2009 lukem
+
+ * Release as "tnftp 20091122"
+
+Sun Nov 15 10:14:44 UTC 2009 lukem
+
+ * Merge NetBSD ftp from 20090520 to 20090915. Change:
+ - Rename internal getline() to get_line() to avoid
+ conflict with libc with former.
+ - Avoid a NULL dereference in an error message.
+
+Sat Nov 14 09:21:19 UTC 2009 lukem
+
+ * Convert to automake & libtool.
+
+Sat Jun 6 07:17:38 UTC 2009 lukem
+
+ * Release as "tnftp 20090606"
+
+Fri May 22 01:11:15 UTC 2009 lukem
+
+ * configure fixes:
+ - Add the time.h headers to accheck_includes, for the strptime check.
+ - Remove the check for el_init in libedit; we're always replacing
+ the library and the presence of strvis() in some versions
+ confuses other checks.
+
+Wed May 20 13:47:43 UTC 2009 lukem
+
+ * Release as "tnftp 20090520"
+
+ * Merge NetBSD ftp from 20070722 to 20090520. Changes:
+ - Only attempt to el_parse() a command unknown by the default
+ parser if editing is enabled.
+ Fixes PR 38589.
+ - Turn off the alarmtimer before resetting the SIGALRM handler
+ back to SIG_DFL.
+ Fixes PR 35630.
+ - Add epsv6 and epsv to disable extended passive mode for ipv6 or
+ both ipv4 and ipv6 respectively. This hack is due to our
+ friends a Juniper Networks who break epsv in ipv6.
+ Should be fixed in ScreenOS 6.2.X.
+ - Improve parsing of chunked transfer chunks per RFC2616:
+ - more stringent chunk-size parsing
+ - ignore optional trailing ';chunk-ext' stuff, instead of barfing
+ - detect EOF before final \r\n.
+ - Use the service name to getaddrinfo() (along with the host
+ name), so that features such as DNS Service Discovery have a
+ better chance of working.
+ Display the service name in various status & error messages.
+ - Don't getservbyname() the :port component of a URL; RFC 3986
+ says it's just an unsigned number, not a service name.
+ - Fix numerous WARNS=4 issues (-Wcast-qual -Wsign-compare).
+ - Fix -Wshadow issues
+ - Update copyrights
+ - Remove clause 3 and 4 from TNF licenses
+ - Rename HAVE_STRUCT_SOCKADDR_SA_LEN to
+ HAVE_STRUCT_SOCKADDR_IN_SIN_LEN to accurately reflect the
+ structure member being used.
+ - Use AF_INET instead of AF_UNSPEC as the default family if
+ !defined(INET6).
+
+ * configure improvements:
+ - Style tweaks.
+ - Use AC_LANG_PROGRAM() instead of AC_LANG_SOURCE()
+ - Add a check for strptime() requiring separators between
+ conversions, and use our replacement one if it does.
+
+Sat Dec 20 15:28:24 UTC 2008 lukem
+
+ * configure improvements:
+ - Move IPv6 check from tnftp.h to configure.ac (as per tnftpd).
+ - Rework option descriptions.
+ - Highlight when tests are for a specific option.
+ - Move configuration results to the end of the file.
+ - Display $prefix in configure results.
+
+Fri Aug 15 03:03:36 UTC 2008 lukem
+
+ * Add a "Configuration results" display at the end of configure.
+ Cosmetic tweaks.
+
+Fri Feb 29 09:45:56 UTC 2008 lukem
+
+ * Support @EXEEXT@ for Cygwin (etc).
+
+Mon Aug 6 04:55:19 UTC 2007 lukem
+
+ * Release as "tnftp 20070806"
+
+ * Add a NEWS file.
+
+ * Reduce differences between NetBSD-ftp and local copy.
+
+ * Merge NetBSD ftp from 20070605 to 20070722.
+ Changes:
+ - Document about:ftp and about:version.
+
+ * Add autoconf check for (Dante) SOCKS5.
+ (Needs run-time testing and more portability testing.)
+
+Mon Jul 23 11:44:42 UTC 2007 lukem
+
+ * Don't use non-standard: u_char u_short u_int.
+ Use uint32_t instead of u_int32_t.
+
+ * Consistently use AS_CASE() and AS_IF() in configure.ac.
+
+ * Don't use defined() with HAVE_DECL_xxx.
+ Use `LL' instead of `L' suffix for fallback
+ defines of LLONG_MIN and LLONG_MAX.
+
+Sun Jul 22 12:00:17 UTC 2007 lukem
+
+ * Include <arpa/nameser.h> if available, and provide fallback #defines.
+
+ * Sync with lib/libc/inet/inet_pton.c 1.3:
+ * Sync to bind 9.3.x version
+ * Update ISC copyright
+ * Fix some lint
+
+ * Sync with lib/libc/inet/inet_ntop.c 1.3:
+ * Sync to bind 9.3.x version
+ * Update ISC copyright
+ * Use socklen_t instead of size_t
+ * Use snprintf() instead of SPRINTF()
+ * Improve detection of various boundary conditions
+
+ * Sync to NetBSD glob.h 1.21, glob.c 1.16:
+ * Standards compliance fix
+ * De-lint
+ * Don't overflow when DEBUG is defined.
+
+ * Sync fgetln.c to tools/compat/fgetln.c 1.7:

+
+ * Sync to config.guess 2007-07-22, config.sub 2007-06-28.
+
+ * Consistency tweaks in configure help strings.
+
+ * Add check for struct sockaddr.sa_len.
+ Change tests for HAVE_foo to defined(HAVE_foo).
+ Replace HAVE_SOCKADDR_SA_LEN with HAVE_STRUCT_SOCKADDR_SA_LEN.
+
+ * Remove pretence of supporting SOCKS for now;
+ no test system is available, and the old
+ autoconf 2.13 support wasn't upgraded to 2.61.
+
+ * configure.ac style consistency tweaks.
+ Move autoconf aux files from ./ to build-aux/
+
+ * Remove duplicate HAVE_STRERROR replacement in tnftp.h.
+
+Thu Jun 7 04:47:47 UTC 2007 lukem
+
+ * Merge NetBSD ftp from 20070510 to 20070605. Changes:
+ - Enforce restriction that (http) proxied URL fetchs don't
+ support being restarted at this time.
+ Addresses NetBSD Problem Report 28697.
+ - Display times in RFC2822 form rather than using ctime(3),
+ since the former is more explicit about the timezone offset.
+ - main: call tzset() to ensure TZ is setup for other <time.h>
+ functions.
+ - remotemodtime(): use strptime() to parse the reply.
+ - fetch_url(): ensure struct tm is zeroed before calling
+ strptime().
+ - Modify parse_url() to consistently strip the leading `/'
+ off ftp URLs.
+ Fixes NetBSD Problem Report 17617.
+ - Use 'RFCnnnn' (with leading 0) instead of 'RFC nnnn', to be
+ consistent with the style in the RFC index.
+ - Refer to RFC3916 instead of 1738 or 2732.
+ - Expand the list of supported RFCs in ftp(1) to contain the
+ document name as well.
+
+Fri May 11 04:39:55 UTC 2007 lukem
+
+ * Update INSTALL and COPYING.
+
+ * Rename HAVE_QUAD_SUPPORT to HAVE_PRINTF_LONG_LONG, and only
+ require support for 'long long' in that check rather than
+ needing sizeof(off_t)>=8, as some systems have a separate
+ off64_t when Large File Support is enabled.
+
+ * config.guess: treat 'i86xen:SunOS:5.*' as 'i86pc:SunOS:5.*'
+
+Thu May 10 15:23:33 UTC 2007 lukem
+
+ * Remove checks for util.h and libutil.h, and replacement for
+ fparseln(), since fparseln() isn't used any more.
+
+ * Merge NetBSD ftp from 20070418 to 20070510. Changes:
+ - Switch from fparseln() to the internal getline() when
+ parsing HTTP headers. Makes ftp a bit more portable
+ (not needing fparseln()) at the expense of not supporting
+ arbitrary long header lines, which I'm not concerned about
+ because we don't support header line continuation either...
+ - Replace references from draft-ietf-ftpext-mlst-NN to RFC 3659.
+ - Fix misplaced const.
+ - Implement copy_bytes() to copy bytes from one fd to another
+ via the provided buffer, with optional rate-limiting and
+ hash-mark printing, using one loop and handle short writes.
+ Refactor sendrequest() and recvrequest() to use copy_data().
+ Addresses NetBSD Problem Report 15943.
+
+Wed May 9 05:24:55 UTC 2007 lukem
+
+ * Fix typo in poll()-based implementation of usleep() replacement.
+
+Wed May 9 04:58:50 UTC 2007 lukem
+
+ * Rename configure.in to configure.ac, as the latter is the
+ preferred name in autoconf 2.61.
+
+ * Convert from autoconf 2.13 to 2.61:
+ * Use a consistent quoting mechanism.
+ * Use modern autoconf macros, #define names, etc.
+ * Search for more header files, and only #include if found.
+ * Remove old-style config.h.in generation.
+ This may fix various tests on platforms such as FreeBSD and OS X.
+
+ * Add -Wl,-search_paths_first to LDFLAGS on OS X (Darwin) if the
+ linker supports it. This is needed so we use our libedit
+ rather than the system one.
+
+ XXX: SOCKS support is currently disabled until I update the
+ autoconf support.
+
+Mon Apr 23 06:04:26 UTC 2007 lukem
+
+ * Merge NetBSD ftp from 20050610 to 20070418. Changes:
+ - Add '-s srcaddr'.
+ - Use IEC 60027-2 2^N based "KiB", "MiB" (etc) instead of
+ 10^n "KB", "MB", ...
+ - Recognize 307 redirect code.
+ - Suppress printing non-COMPLETE reply strings when EPSV/EPRT
+ fails and we fall-back to PASV/PORT. Should fix a problem
+ with the emacs ftp wrapper.
+ - Fix display of 'Continue with <cmd>' messages.
+ - Prevent segfaults in .netrc parsing.
+ - Flush stdout before each command; ftp as slave process on
+ a pipe should work.
+ - getpass() can return NULL in some implementations; cope.
+ - Support '-q quittime' when waiting for server replies.
+ - Various spelling & grammatical fixes in the manual.
+ - Plug some memory leaks.
+ - If a file upload (via -u) fails, return an non-zero exit
+ value based on the index of the file that caused the
+ problem (a la auto-fetch retrieval).
+ - Coverity fixes for CIDs: 873 874 875 1447 1448 2194 2195 3610
+ - Don't remove trailing character during auth_url()
+ - Fix progressbar display on narrow terminals (<43 columns)
+
+Fri Mar 16 06:00:14 UTC 2007 lukem
+
+ * Change the return value of the replacement gai_strerror()
+ from "char *" to "const char *", to match the current
+ standards.
+ Problem noted by Thomas Klausner.
+
+Thu Oct 26 07:24:22 UTC 2006 lukem
+
+ * Correctly parse "AM" and "PM" in the replacement strptime().
+ Problem noted by Kathryn Hogg.
+
+Sat Jun 25 06:27:00 UTC 2005 lukem
+
+ * Release as "tnftp 20050625"
+
+ * Simplify the detection & replacement of dirname() and fparseln()
+ and just use AC_REPLACE_FUNCS.
+ (We don't care if the vendor has a working version in -lgen or -lutil
+ instead of -lc; they'll get our replacement version in that case).
+ Fixes build issue on older Darwin where the previous autoconf check
+ wouldn't find dirname() in the default system libraries.
+
+ * Only provide a prototype for dirname() if we can't find one in
+ <libgen.h>
+
+ * Search for NS_IN6ADDRSZ instead of IN6ADDRSZ, since we use the
+ former and not the latter and older Darwin has the former.
+ (This allows INET6 support to be enabled on Darwin 7.9.0)
+
+Mon Jun 13 09:22:13 UTC 2005 lukem
+
+ * Tweak SOCKS5 support:
+ acconfig.h:
+ - fix a comment
+ - ensure close() is replaced
+ - list entries in the same order as aclocal.m4
+ (and the SOCKS5 FAQ)
+ aclocal.m4:
+ - ensure getpeername() is replaced
+ - don't replace listen() twice
+
+Fri Jun 10 04:39:33 UTC 2005 lukem
+
+ * Release as "tnftp 20050610"
+
+ * Add dependencies on ${srcdir}/../tnftp.h and ../config.h
+
+ * Merge NetBSD ftp from 20050609 to 20050610. Changes:
+ - Implement getline() to read a line into a buffer.
+ - Convert to use getline() instead of fgets() whenever reading
+ user input to ensure that an overly long input line doesn't
+ leave excess characters for the next input operation to
+ accidentally use as input.
+ - Zero out the password & account after we've finished with it.
+ - Consistently use getpass(3) (i.e, character echo suppressed)
+ when reading the account data. For some reason, historically
+ the "login" code suppressed echo for Account: yet the "user"
+ command did not!
+ - Display the hostname in the "getaddrinfo failed" warning.
+ - Appease some -Wcast-qual warnings. Fixing all of these
+ requires significant code refactoring. (mmm, legacy code).
+
+Thu Jun 9 16:49:05 UTC 2005 lukem
+
+ * src, libnetbsd: Excise RCSID block, rather than using
+ #if 0 ... #endif. The point was to minimise RCSID
+ conflicts, and the latter isn't helping there.
+
+ * Merge NetBSD ftp from 20050531 to 20050609. Changes:
+ - Only print the "Trying <address>..." message if verbose
+ and there's more than one struct addrinfo in the
+ getaddrinfo() result.
+ - Don't use non-standard "u_int".
+
+Wed Jun 1 15:08:01 UTC 2005 lukem
+
+ * Look for dirname(3), which may be in -lgen on IRIX, and
+ replace it if not found..
+
+Wed Jun 1 11:48:58 UTC 2005 lukem
+
+ * libnetbsd:
+ - Don't use non-standard: u_char u_short u_int.
+ - Use uint32_t instead of u_int32_t.
+ - Don't use register.
+
+ * libedit: Don't use non-standard uint or u_int.
+
+Tue May 31 02:23:08 UTC 2005 lukem
+
+ * tnftp.h: need <libgen.h> for dirname(3)
+
+ * Merge ftp from 20050513 to 20050531. Changes:
+ - Helps if the definition of xconnect() matches its
+ declaration....
+ - Fix some cast issues highlighted by Scott Reynolds using
+ gcc 4 on OSX.4
+ - Use size_t instead of int where appropriate.
+ - Make this compile on sparc64 (size_t != int).
+ - Printf field widths and size_t don't always mix well, so
+ cast to int. Fixes build problem for alpha.
+ - Some const cleanups.
+ - tab cleanup
+ - Improve method used in fileindir() to determine if `file'
+ is in or under `dir': realpath(3) on non-NetBSD systems may
+ fail if the target filename doesn't exist, so instead use
+ realpath(3) on the parent directory of `file'.
+ Per discussion with Todd Eigenschink.
+ - formatbuf(): fix %m and %M to use the hostname, not the
+ username.
+ - fetch_ftp(): preserve 'anonftp' across a disconnect() so
+ that multiple ftp auto-fetches on the same command line
+ login automatically.
+ - auto_fetch(): use an initialized volatile int to appease
+ IRIX cc.
+
+ * Merge libedit from NetBSD 20050105 to 20050531. Changes include:
+ - Rui Paulo: Incorrect tok_line and tok_str declarations.
+ - Remove clause 3 from the UCB license.
+ - Luke Mewburn: Don't abuse unconstify'ing a string
+ and writing to it, because you'll core dump. Also remove
+ extra const that gives pain to the irix compiler.
+ - Make sure we flush after we prepare when we are unbuffered
+ otherwise the prompt will not appear immediately.
+ - Terminate the arglist with a NULL instead of 0.
+ (Shuts up gcc4.x)
+
+Sat May 28 13:19:38 UTC 2005 lukem
+
+ * libnetbsd/strvis.c:
+ - Sync to NetBSD's vis.c 1.33:
+ Use malloc(3) instead of alloca(3).
+ - Remove extraenous #endif
+
+Fri May 27 05:46:58 UTC 2005 lukem
+
+ * libnetbsd/strvis.c: Sync to NetBSD's vis.c 1.30:
+ Use a more standard TNF license.
+
+ * libedit/sig.c: Include "src/progressbar.h" for xsignal_restart()
+ prototype.
+
+ * Ensure that fallback #define of __attribute__ is available.
+ Fixes build problem on HP-UX with cc.
+
+Thu May 26 14:21:08 UTC 2005 lukem
+
+ * Extend xpoll()'s HAVE_SELECT implementation to support POLLRDNORM,
+ POLLWRNORM, and POLLRDBAND - the latter using exceptfds.
+ Per discussion with Christos Zoulas.
+
+Mon May 16 13:33:27 UTC 2005 lukem
+
+ * Pull in <poll.h> or <sys/poll.h> if they exist even if we're
+ not using poll, as struct pollfd might exist in those.
+ Fixes build problem on OSX.3.
+
+ * Separate CPPFLAGS from CFLAGS.
+
+ * Sync various files in libnetbsd with the original versions
+ in NetBSD. Notable changes
+ - Convert 4 clause UCB license to 3 clause.
+ - Use strlcpy instead of strcpy.
+ - Update ISC copyright.
+ - Use NS_INADDRSZ, NS_IN6ADDRSZ and NS_INT16SZ instead of
+ equivalents without NS_ prefix.
+ - Use socklen_t instead of size_t where appropriate.
+ - Improve bounds checking.
+ - Don't update the size of allocated storage until
+ realloc succeeds.
+ - Fix comment about return value.
+ - Reverse the order of two loop invariant to make
+ 'strlcat(0, "foo", 0)' not get a SEGV.
+ - Use Todd C. Miller's latest copyright notice (more loose).
+ - Use "long long" instead of "quad" in various
+ comments & constants.
+ - Support VIS_HTTPSTYLE.
+ - Implement svis(), strsvis(), strsvisx(), strunvisx().
+
+ * Prefer poll over select when implementing replacement usleep().
+
+Sat May 14 04:44:35 UTC 2005 lukem
+
+ * Release "tnftp 20050514"
+
+ * Fail if we can't find a library with tgetent (needed for libedit).
+ NetBSD PR pkg/28925.
+ * Improve quoting when using various autoconf macros.
+
+ * Merge NetBSD-ftp 20050513:
+ - Correct the "optlen" argument passed to getsockopt(3) and
+ setsockopt(3) in various places. Fixes a problem noted by
+ Allen Briggs.
+ - Improve warning printed when connect(2) for the data
+ channel fails.
+
+Wed May 11 04:19:43 UTC 2005 lukem
+
+ * Release "tnftp 20050511"

+ - Prevent an overly-long input line causing a core dump when
+ editing is enabled.
+ Issue noted by Ryoji Kanai in FreeBSD Problem Report # 77158.
+ - Implement a timeout on the accept(2) in dataconn() and the
+ connect(2) in xconnect() by temporarily setting O_NONBLOCK
+ on the socket and using xpoll() to wait for the operation
+ to succeed. The timeout used is the '-q quittime' argument
+ (defaults to 60s for accept(2), and the system default for
+ connect(2)). Idea inspired by discussion with Chuck Cranor.
+ This may (indirectly) fix various problems with timeouts in
+ active mode through broken firewalls.
+ - Implement xpoll() as a wrapper around poll(2), to make it
+ easier to replace on systems without a functional poll(2).
+ Unconditionally use xpoll() instead of conditionally using
+ select(2) or poll(2).
+ - In fetch_url(), don't call freeaddrinfo(res0) too early, as
+ we use pointers to its contents later in the function.
+ Problem found by Onno van der Linden.
+ - Fix ftp url reget when globs are being used.
+ Provided by Mathieu Arnold <mat at FreeBSD.org>.
+ - Factor out common string processing code eliminating static
+ buffers, making functions that should be static be static,
+ and cleaning up const usage. Added a guard against buffer
+ overflow, but the domap function is a bit too complicated
+ to tackle right now.
+ - Clean up whitespace.

+ * Unixware 7.1.1 implements RFC 2133 (Basic Socket Interface
+ Extensions for IPv6) but not the successor RFC 2553. The configure
+ script detects this and decides that tnftp needs to compile its own
+ version of getaddrinfo(). This produces the error message
+ /usr/include/netdb.h:248: `getaddrinfo' previously defined here
+ because Unixware provides an implementation of getaddrinfo() in
+ netdb.h instead of a prototype declaration :-/. Since netdb.h
+ cannot be omitted, we will always get this definition and tnftp's
+ version of getaddrinfo will always create a conflict. This ugly
+ preprocessor hack works around the problem. Hints for a better
+ solution welcome. Fix from pkgsrc/net/tnftp.
+
+ * Workaround poll() being a compatibility function on Darwin 7
+ (MacOSX 10.3) by adding a custom test for _POLL_EMUL_H_ which

+ systems have poll.h, so only do the poll() test if at least one
+ of the header files is found. Fix from pkgsrc/net/tnftp.

+
+ * Merge NetBSD-ftp 20050103:
+ - Forbid filenames returned from mget that aren't in (or below)
+ the current directory. The previous behaviour (of trusting
+ the remote server's response when retrieving the list of
+ files to mget with prompting disabled) has been in ftp
+ ~forever, and has been a "known issue" for a long time.
+ Recently an advisory was published by D.J. Bernstein on
+ behalf of Yosef Klein warning of the problems with the
+ previous behaviour, so to alleviate concern I've fixed
+ this with a sledgehammer.
+ - Remember the local cwd after any operation which may
+ change it.
+ - Use "remotecwd" instead of "remotepwd".
+ - Add (unsigned char) cast to ctype functions
+ - Ensure that "mname" is set in ls() and mls() so that an
+ aborted confirm() prints the correct name.
+ Problem highlighted & suggested fix from PR [bin/17766]
+ by Steve McClellan.
+ - If an ftp auto-fetch transfer is interrupted by SIGINT
+ (usually ^C), exit with 130 instead of 1 (or rarely, 0).
+ This allows an ftp auto-fetch in a shell loop to correctly
+ terminate the loop.
+ Should fix PR [pkg/26351], and possibly others.
+ - Save approximately 8K by not including http authentication,
+ extended status messages and help strings when the
+ appropriate options are set.
+ - Move UCB-licensed code from 4-clause to 3-clause licence.
+ Patches provided by Joel Baker in PR 22365, verified by
+ Alistair Crooks.
+ - Always decode %xx in a url's user & pass components.
+ - Only remember {WWW,Proxy}-Authenticate "Basic" challenges; no
+ point in tracking any others since ftp doesn't support them.
+ - Improve the parsing of HTTP responses.
+ - Don't base64 encode the trailing NUL in the HTTP basic auth
+ response. Problem noted by Eric Haszlakiewicz.
+ - Improve parsing of HTTP response headers to be more RFC2616
+ compliant, and skip LWS (linear white space; CR, LF, space,
+ tab) and the end of lines and between the field name and
+ the field value. This still isn't 100% compliant, since we
+ don't support "multi line" responses at this time.
+ This should fix PR [bin/22611] from TAMURA Kent (although I
+ can't easily find a http server to reproduce the problem
+ against.)
+ - Fix a minor memory leak when parsing HTTP response headers.
+ - Don't unnecessarily display a 401/407 error when running
+ with -V. Fix from PR [bin/18535] by Jeremy Reed.
+ - Don't warn about "ignored setsockopt" failures unless
+ debugging is enabled. Suggested by Todd Vierling.
+ - Allow empty passwords in ftp://user:@host/file auto-fetch
+ URLs, per RFC 1738. Requested by Simon Poole.
+ - correct URL syntax in comment
+ - Note potentially surprising file-saving behaviour in case
+ of HTTP redirects
+ - -n is ignored for auto-fetch transfers
+ - If connect(2) in xconnect() fails with EINTR, call select(2)
+ on the socket until it's writable or it fails with something
+ other than EINTR. This matches the behaviour in SUSv3, and
+ prevents the problem when pressing ^T (SIGINFO, which is
+ marked as restartable) during connection setup would cause
+ ftp to fail with EADDRINUSE or EALREADY when the second
+ connect(2) was attempted on the same socket. Problem found
+ and solution provided by Maxime Henrion <mux at freebsd.org>.
+ - Add -q to usage. From Kouichirou Hiratsuka in PR 26199.

+ setting while libedit was undoing it (setting the tty to a
+ sane state and totally confusing xxgdb's parser).
+ this diff simply disables libedit if both readline emulation
+ and "stty -echo" are used/set. that is enough to make
+ xxgdb work once again, but (XXX) this is not how GNU readline
+ handles stty -echo (it does not echo anything, but editing

+ convert it to a numeric port number
+ * use parseport() in parse_url() and hookup()
+ * don't try and lookup the port number using getaddrinfo(),
+ as it's too hard to separate a failed host name lookup from
+ a failed service name lookup. this was causing lossage on
+ systems that don't have `http' in services(5) (such as
+ solaris), but only crept in when we started using
+ getaddrinfo() unconditionally.
+
+Wed Aug 2 23:43:50 EST 2000 lukem
+
+ * crank to version 1.5 beta3
+
+ * define NO_LONG_LONG not NO_QUAD
+
+ * detect if struct sockaddr.sa_len exists (rather than relying upon
+ #ifdef BSD4_4)
+
+ * detect if socklen_t exists, and if not, typedef as unsigned int
+
+ * detect if struct addrinfo exists, and if not declare it and #define
+ associated EAI_, AI_, and NI_ defines.
+
+ * look for & replace: getaddrinfo(), getnameinfo(), inet_ntop(),
+ inet_pton()
+ * look for gethostbyname2()
+
+ * don't bother looking for hstrerror() or inet_aton() anymore
+
+ * include <arpa/nameser.h> and <stddef.h>
+
+ * define USE_SELECT instead of __USE_SELECT
+
+ * always define HAVE_H_ERRNO
+
+ * add Brian Stark to THANKS, for lots of AIX porting feedback
+
+ * improve detection of sin_len for AIX (now part of sa_len test)
+
+ * add functions needed by recent ftp import:
+ getaddrinfo(), getnameinfo(), inet_ntop(), inet_pton()
+ remove functions not needed anymore:
+ hstrerror(), inet_aton()
+
+ * use #if HAVE_ISSETUGID not #ifdef
+
+ * update from NetBSD-current (20000802):
+ - rename NO_QUAD to NO_LONG_LONG, QUAD* -> LL* and add ULL*
+ (unsigned) equivalents. name change suggested by Klaus
+ Klein <kjk at NetBSD.org>
+ - change defined(BSD4_4) || HAVE_SIN_LEN tests into
+ HAVE_SOCKADDR_SA_LEN, and set the latter if BSD4_4 exists
+
+Mon Jul 31 10:59:10 EST 2000 lukem
+
+ * merge ftp from NetBSD-current (20000731)
+ - we can't just rename BSD4_4 -> HAVE_SIN_LEN, since bsd
+ systems define BSD4_4; change tests to test for either
+ defined(BSD4_4) or HAVE_SIN_LEN
+ - more KNF
+
+Sun Jul 30 16:55:09 EST 2000 lukem
+
+ * merge ftp from NetBSD-current (20000730):
+ - clean up NO_QUAD support: create helper #defines and use as
+ appropriate:
+ #define NOQUAD ! NOQUAD
+ ------- ------ - ------
+ QUADF "%ld" "%lld"
+ QUADFP(x) "%" x "ld" "%" x "lld"
+ QUADT long long long
+ STRTOL(x,y,z) strtol(x,y,z) strtoll(x,y,z)
+ - always use getaddrinfo() and getnameinfo() instead of
+ maintaining two code paths.
+ - rename __USE_SELECT to USE_SELECT
+ - rename BSD4_4 to HAVE_SIN_LEN
+ - replace union sockunion {} with struct sockinet {}, and
+ modify the code accordingly. this is possibly more portable,
+ as it doesn't rely upon the structure alignment within the
+ union for our own stuff.
+
+Fri Jul 28 22:11:17 EST 2000 lukem
+
+ * merge ftp from NetBSD-current (20000728):
+ - no trailing , on last item (FEAT_max) in enum
+ - rename "opts" to "remopts", so people used to "o host"
+ don't get bitten
+
+Wed Jul 26 18:59:19 EST 2000 lukem
+
+ * merge ftp from NetBSD-current (20000726):
+ - add support for FEAT and OPTS commands with `features' and
+ `opts'. (from RFC 2389).
+ - add support for MLST & MLSD (machine parseble listings)
+ with 'mlst', 'mlsd' and 'pmlsd' (mlsd |$PAGER) commands.
+ (from draft-ietf-ftpext-mlst-11)
+ - rename remotesyst() to getremoteinfo(), and modify to parse
+ the result from FEAT (if supported), and take into account
+ the support for the various extensions such as MDTM, SIZE,
+ REST (STREAM), MLSD, and FEAT/OPTS.
+ - put each feature into one of the following categories:
+ - known to work (explicit FEAT)
+ - unknown but assume works until explicit failure,
+ when it's then tagged as `known not to work'.
+ - known not to work (FEAT succeeded but didn't return
+ anything, or was unknown and then explicit failure)
+ assign results into features[] matrix.
+ - add support to getreply() so that an optional callback will
+ be called for each line received from the server except for
+ the first and last. this is used in FEAT (and MLST) parsing.
+ - modify various commands to check if REST (STREAM), MDTM and
+ SIZE are explicitly or implicitly supported before using.
+ - fix `syst' when verbose is off.
+ - minor knf (indent goto labels by one space, etc).
+ - simply various command usage handlers by assuming that
+ argv != NULL except for quit() and disconnect().
+ - errx?/warnx? audit. do not pass variable alone, use %s.
+
+ * check for issetugid() and don't use in libedit if it doesn't exist.
+
+ * merge libedit from NetBSD-current (20000726):
+ * Only look in home directory for .editrc. (Discussed
+ with Christos.)
+
+ * in glob.c #undef TILDE before redefining, because some AIX systems
+ #define TILDE in <sys/ioctl.h>
+
+Mon Jul 10 00:28:51 EST 2000 lukem
+
+ * released lukemftp 1.4
+
+Thu Jun 15 23:28:49 EST 2000 lukem
+
+ * merge ftp from NetBSD-current (20000615):
+ * migrate the SYST parsing from setpeer() into a separate
+ remotesyst(). call remotesyst() only when login has been
+ successful some servers don't let you run SYST until you've
+ successfully logged in.
+ * in fetch_ftp(), always call setpeer() with autologin
+ disabled, and use the following ftp_login() to DTRT. this
+ prevents ftp from trying to login a second time if the
+ first autologin fails when connecting to a remote site
+ anonymously using autofetch.
+ * reset unix_proxy and unix_server in cleanuppeer()
+ * missed a function conversion in the KNF sweep...
+
+Mon Jun 12 01:16:12 EST 2000 lukem
+
+ * change lukemftp.h to check !HAVE_STRDUP instead of !HAVE_STRSUP.
+ fixes compile problem on systems which have strdup() as a macro.
+
+ * merge ftp from NetBSD-current (20000612):
+ from itojun: better fix for previous (doesn't need
+ in_addr_t or u_int32_t)
+
+Sun Jun 11 12:19:52 EST 2000 lukem
+
+ * merge ftp from NetBSD-current (20000611):
+ portability fixes for lukemftp:
+ * initconn(): use in_addr_t instead of u_int32_t when
+ manipulating IPv6 addresses (and assume anything with ipv6
+ has in_addr_t; if not, i'll add an autoconf test for it)
+ * ai_unmapped(): not all systems have sin_len; so only set
+ #ifdef BSD4_4
+ * fix some lint
+
+Mon Jun 5 21:10:31 EST 2000 lukem
+
+ * released lukemftp 1.3
+
+Mon Jun 5 19:53:49 EST 2000 lukem
+
+ * convert various support files to ANSI C
+
+ * look for strtoll() instead of strtoq()
+
+ * update COPYRIGHT, THANKS, NEWS
+
+ * merge ftp from NetBSD-current (20000605):
+ - fix ai_unmapped() to be a no-op in the !def INET6 case
+ - display `(-INET6)' at the end of the version string if
+ !def INET6
+ - clarify in the man page that IPv6 support may not be present
+ (for lukemftp :)
+
+ * ensure <vis.h> has VIS_WHITE et al
+
+Sun Jun 4 18:00:07 EST 2000 lukem
+
+ * merge ftp from NetBSD-current (20000604):
+ - Change `ls' to use the `LIST' and not `NLST' FTP protocol
+ command. Now that after many years on not caring we find
+ certain popular ftp servers are starting to obey RFC959 to
+ the letter of the law and will only return a list of
+ filenames (not directories or other filetypes) in the
+ output of `NLST', then `LIST' is more useful in this case.
+ (Note that the aforementioned pedanticness means that
+ filename completion isn't as useful as it could be...)
+ Fixes [bin/8937] by David A. Gatwood
+ <dgatwood at deepspace.mklinux.org>
+ - convert to ANSI KNF
+ - Add support for `fget localfile', which reads a list of
+ filenames to retrieve from localfile. Based on work by
+ Darren Reed.
+ - Update copyright dates.
+ - s/strtoq/strtoll/ (the latter is standardised)
+ - Add support for 'ftp -u url file ...', to upload a list of
+ files to given url. Mostly based on [bin/10019] by Scott
+ Aaron Bamford <sab at ansic.net>
+ - convert IPv4 mapped address (::ffff:10.1.1.1) into real IPv4
+ address before touching it. IPv4 mapped address complicates
+ too many things in FTP protocol handling.
+ - do not pass scoped IPv6 address notation on Host: directive,
+ since scope identifier is local to the originating node.
+ do not allow scoped IPv6 address notation in URL, if it is
+ via proxy.
+ - fixes from cgd:
+ * sanity check a length (otherwise certain bogus responses
+ can crash ftp)
+ * allow a transfer encoding type of `binary'; certain
+ firewall vendors return this bogus type...
+ - make debugging output unambiguous on IPv6 numeric addrs
+ (don't use host:port)
+ - http://[::1]:8080/ is legal.
+ - send Host: directive with RFC2732 bracket notation for IPv6
+ numeric, otherwise "host:port" is ambiguous to servers
+ (clarification will be submitted as update to RFC2732).
+ - only use getaddrinfo() et al if both NI_NUMERICHOST *and*
+ INET6 are defined... (allows --disable-ipv6 in lukemftp's
+ configure script to disable this as well, which is good for
+ testing when it appears getaddrinfo() is borken)
+ - updated comment on IPv4 mapped address. sync with kame.
+ - Fix examples on using pipes in local filenames. AFAICT,
+ ftp has always required `dir . |more' not as `dir |more'
+ treats `|more' as the remote filename. Resolves [bin/9922]
+ by Geoff Wing <mason at primenet.com.au>
+ - ftp(1): treats IPv4 mapped destination as IPv4 peer, not
+ native IPv6 peer. this does not support network with SIIT
+ translator.
+ - inhibit too-noisy message for scoped address data transfer
+ (will be enabled in "debug" mode).
+ - only use IPTOS_ setsockopt()s if they're defined (e.g, SunOS
+ doesn't). from Havard.Eidnes at runit.sintef.no
+ - allow IPv6 extended numeric address in host part.
+ (draft-ietf-ipngwg-scopedaddr-format-01.txt). fixes PR 9616.
+
+ * merge libedit from NetBSD-current (20000604):
+ - use strtol() (instead of atoi()) for sane error detection
+
+Wed May 31 19:24:53 EST 2000 lukem
+
+ * merge libedit from NetBSD-current (20000531):
+ - Fix refresh glitches when using auto-margin.
+ - Don't dump core on empty .editrc files.
+ - el_insertstr takes a "const char *" not "char *" now as it
+ doesn't modify the argument.
+
+Thu Feb 3 20:19:40 EST 2000 lukem
+
+ * released lukemftp 1.2
+
+Tue Feb 1 09:47:51 EST 2000 lukem
+
+ * add --enable-ipv6 and --disable-ipv6 to configure
+
+ * modify libedit/sig.? to use sigfunc instead of sig_t, and
+ deprecate autoconf tests for retsigtype and sig_t.
+ This fixes portability problems with Digital UNIX 5.0.
+
+ * merge ftp from NetBSD-current (20000201):
+ - define private type `sigfunc' as
+ typedef void (*sigfunc) __P((int));
+ and replace use of sig_t and void (*)(int).
+ certain other OSes define sig_t differently to that (they
+ add extra arguments), and it causes problems due to
+ function mismatches, etc...
+
+Wed Jan 26 22:54:38 EST 2000 lukem
+
+ * search for tgetent() in -ltermcap then -lcurses and -lncurses
+
+ * merge ftp from NetBSD-current (20000126):
+ - roll back to using sscanf() instead of strptime() to parse
+ `yyyymmddhhmmss' strings, since the latter technically can't
+ parse dates without non alphanumerics between the elements
+ (even though NetBSD's strptime() copes).
+
+Tue Jan 25 19:09:37 EST 2000 lukem
+
+ * merge ftp from NetBSD-current (20000125):
+ - complete_ambiguous(): be consistent about completing
+ unambiguous matches; if the word is already complete then
+ return CC_REFRESH so that the higher layer may append a
+ suffix if necessary. Fix from Launey Thomas <ljt at alum.mit.edu>
+ - change references from draft-ietf-ipngwg-url-literal-01.txt
+ to RFC2732
+ - work around bug in apache 1.3.9 which incorrectly puts a
+ trailing space after the chunksize. noted by Jun-ichiro
+ itojun Hagino <itojun at itojun.org> in [bin/9096]
+ - work around lame ftpd's that don't return a correct post-Y2K
+ date in the output of `MDTM'. obviously the programmer of
+ aforementioned lame ftpd's did something like
+ "19%02d", tm->tm_year
+ instead of
+ "%04d", tm->tm_year + TM_YEAR_BASE
+ fixes [bin/9289] by jbernard at mines.edu
+
+ * merge libedit from NetBSD-current (20000125):
+ - PR/9244: Kevin Schoedel: libedit dumps bindings
+ inconsistently
+ - PR/9243: Kevin Schoedel: libedit ignores repeat count
+ - Add support for automatic and magic margins (from tcsh)
+ This makes the rightmost column usable on all programs
+ that use editline.
+
+Tue Dec 21 08:59:22 EST 1999 lukem
+
+ * update INSTALL notes for some systems
+
+ * if sl_init() exists, check return value of sl_add() is int and
+ compile in a replacement copy if it's not the case
+
+ * don't look for <stringlist.h> - always use local prototypes; older
+ NetBSD systems may have conflicting prototypes
+
+Mon Dec 20 11:21:28 EST 1999 lukem
+
+ * merge ftp from NetBSD-current (19991220):
+ - Move version from ftp_var.h to version.h
+ - Fix chunked support; probably broke after rate limiting was added.
+ Problem noticed/debugging assisted by giles lean
+ <giles at nemeton.com.au>.
+ - remove unnecessary freeaddrinfo(res), since res0 was changed to be
+ freed earlier in itojun's last commit. fixes [bin/8948].
+ - remove `const char *reason'; it was being assigned but not used.
+ - fix memory leak in fetch_url (no freeaddrinfo was there).
+ sync with recent KAME.
+ - separate out the main `data pump' loop into two: one that supports
+ rate limiting and one that doesn't. simplifies the code, and speeds
+ up the latter case a bit, at the expense of duplicating a few
+ lines...
+
+Sun Nov 28 18:20:41 EST 1999 lukem
+
+ * merge ftp from NetBSD-current (19991128):
+ - implement xsl_init() and xsl_add(); error checking forms of
+ sl_{init,add}()
+ - fix bug where the second press of <TAB> on an empty word (i.e, list
+ all options) may have resulted in an strncmp() against NULL.
+ (detected by _DIAGASSERT())
+ - in cleanuppeer(), reset username to NULL after free()ing it.
+ fixes [bin/8870] by Wolfgang Rupprecht <wolfgang at wsrcc.com>
+ - complete_remote(): use remglob("", ...) instead of remglob(".", ...),
+ for listings of the current working directory; some ftp servers don't
+ like `NLST .'.
+ [noted by Giles Lean <giles at nemeton.com.au>]
+ - recvrequest(): treat remote=="" as remote==NULL when calling
+ command(). (to support the above change)
+ - support `[user@]' in `[user@]host' and `[user@]host[:][path]'.
+ [based on idea (and initial code) from David Maxwell <david at fundy.ca>]
+ - `idle' may be invoked without any args
+ - reformat some comments
+ - reformat usage string in program and man page
+ - call updateremotepwd() after successful login, not after successful
+ connect
+ - always call setsockopt(, IPPROTO_IP, IP_TOS, ) (et al); using #if
+ defined(IPPROTO_IP) doesn't work on certain foreign systems where
+ enums instead of #defines are used...
+ [noted by Matthias Pfaller <leo at dachau.marco.de>]
+
+Mon Nov 15 23:01:58 EST 1999 lukem
+
+ * released lukemftp 1.1
+
+Mon Nov 15 09:07:01 EST 1999 lukem
+
+ * merge libedit from NetBSD-current (19991115):
+ - instead of using a private coord_t global variable to store
+ the size of the rprompt, use the previously unused coord_t
+ el->el_rprompt.p_pos
+
+Sat Nov 13 14:42:22 EST 1999 lukem
+
+ * support caching of results in AC_MSG_TRY_{COMPILE,LINK}
+ autoconf tests
+
+ * add NEWS file
+
+ * clarify copyright statement in COPYING
+
+ * merge ftp from NetBSD-current (19991113):
+ - implement `set rprompt'; right side version of `set prompt'.
+ depends on EL_RPROMPT support i added to editline(3).
+ - allow $FTPPROMPT and $FTPRPROMPT to override defaults for
+ the relevant prompts
+ - move `%' formatting code from prompt() to expandbuf().
+ - implement `%.' and `%c', similar to the same % codes in
+ tcsh(1) (functionality I added to tcsh nearly 6 years ago),
+ except that `%.' always does `...trailing' and `%c' always
+ does `/<x>trailing'.
+ - unknown `%foo' codes get printed as `%foo'
+ - implement updateremotepwd(); update the global variable
+ `remotepwd' to contain the remote working directory.
+ - add `set prompt', a user configurable prompt. (defaults to
+ `ftp> '). the following escape characters a la tcsh(1) are
+ supported: %/, %m, %M, and %n.
+ - add global var `username'; used by prompt code
+ - fix a couple of minor memory leaks
+ - bump version
+ - prevent minor memory leak (unnecessary strdup)
+ - implement restarting file:/// non-proxied http:// URLs
+ (with -R).
+ - fix a semicolono which stopped file:/// from working
+ - split the version string into product and version
+ - be consistent about reporting the version between:
+ + status command
+ + about:version URL fetch
+ + User-agent sent in http requests
+ - hookup(): when using getservbyname() (when getaddrinfo()
+ isn't available), if the provided port is a valid number
+ use that rather than trying to do getservbyname() against
+ it. fixes a problem on foreign systems noted by Chuck
+ Silvers <chuq at chuq.com>
+ - support `about:version'. also display the version in the
+ output of `status'.
+
+ * merge libedit from NetBSD-current (19991113):
+ - implement printing a right-side prompt. code derived from
+ similar work I wrote for tcsh(1) three years ago.
+ - implement EL_RPROMPT, which allows a setting/getting of a
+ function which returns a string to be used as the
+ right-side prompt.
+
+ * replace manually managed config.h.in with acconfig.h and use
+ autoheader to generate the former.
+
+ * add missing entry for `#undef write' in acconfig.h (for SOCKS)
+
+ * configure.in:
+ - use `LL' suffix on long long constant used to test
+ snprintf("%lld")
+ - test for EL_RPROMPT instead of EL_EDITMODE, since the
+ former is is a newer required feature
+
+ * in makelist, set LC_ALL="C", in case the locale confuses awk.

+
+ * put VERSION string into lukemftp.h, and display with the `status'

+
+Mon Oct 25 11:36:59 EST 1999 lukem
+
+ * merge ftp from NetBSD-current (19991025):
+ - fix up confirm() (broke `a' and `p' in last commit)
+ - simplify main loop (don't need `top' variable any more)
+ - use a struct sockaddr_in6.sin6_addr for the result from inet_pton(),
+ rather than u_char buf[16]
+ - add a few more comments
+
+ new features:
+ - add `usage'; displays the usage of a command.
+ implemented by calling the c_handler() with argc = 0, argv =
+ "funcname".
+ - add `passive auto'; does the same as $FTPMODE=auto.
+ - add `set [option value]'; display all options, or set an option to
+ a value.
+ - add `unset option'; unset an option.
+ - add getoptionvalue() to retrieve an option's value, and replace a few
+ global variables with calls to this.
+ - implement cleanuppeer(), which resets various bits of state back to
+ `disconnected'. call in disconnect() and lostpeer().
+ - support completing on `options'.
+ - improve recovery after a SIGINT may have closed the connection.
+ XXX: there's still a couple to fix
+
+ other stuff:
+ - various consistency fixes in the man page.
+ - ensure that the command usage strings in the code and man page
+ match reality.
+ - mput/mget: check that the connection still exists before each xfer.
+ - minor cosmetic changes in confirm().
+ - set code correctly in sizecmd() and modtime()
+ - don't need \n in err() strings.
+ - change lostpeer to take an argument (rather than casting
+ (sig_t)lostpeer in signal handlers)
+ - knf and whitespace police.
+
+Sun Oct 24 17:02:59 EST 1999 lukem
+
+ * merge libedit from NetBSD-current (19991024):
+ - don't assume locales are not working - it may not be
+ the case
+ - re_refresh(): cast the character passed to re_addc() to
+ unsigned char, so we don't end up calling isprint() with
+ negative value when chars are signed and character value
+ is >= 128
+ - Fix pointer arithmatic (caused problems on LP64, including
+ ftp dumping core when `edit' was turned off then on).
+ Problem solved by David Huggins-Daines <dhd at eradicator.org>
+

+
+ * released 1.0b6
+
+ * merge from NetBSD-current (19991012):
+ a few user interface and cosmetic tweaks:
+ - confirm(): move from util.c to cmds.c. display mnemonic
+ string in its prompt. add support for `q' (terminate
+ current xfer), `?' (show help list)
+ - in various signal handlers, output a linefeed only if
+ fromatty.
+ - if fgets(stdin) returned NULL (i.e, EOF), clearerr(stdin)
+ because you don't want future fgets to fail. this is not
+ done for the fgets() in the main command loop, since ftp
+ will quit at that point.
+ - unless ftp is invoked with -a, don't retain the anonftp
+ setting between hosts (`ftp somehost:' sets anonftp, but
+ you don't want that to `stick' if you close that connection
+ and open a new one).
+
+Mon Oct 11 23:06:38 EST 1999 lukem
+
+ * check for working const
+
+ * reorganise addition of -lukem to LIBS (was being added twice)
+
+ * merge from netbsd-current:
+ - use sigjmp_buf instead of jmp_buf for sigsetjmp() buffer
+
+ * libedit: don't bother generating & compiling editline.c, since
+ its component parts are compiled anyway.
+
+Sun Oct 10 12:08:39 EST 1999 lukem
+
+ * released 1.0b5
+
+ * in libedit, use xsignal_restart() (from src/util.c) instead of
+ signal(); the isn't guaranteed to work on some foreign systems
+ (e.g, IRIX) if sigaction() is used in the same program.
+
+ * merge from netbsd-current:
+ - use sigsetjmp()/siglongjump() instead of setjmp()/longjmp();
+ the latter don't save the signal mask on some foreign systems.
+ - ensure signal handlers don't use stdio and do reset errno
+ if they don't exit with siglongjmp()
+ - use a common SIGINT handler for {send,recv}request()
+ - allow a second SIGINT during the "xfer aborted. waiting for
+ remote to finish abort." stage. if this occurs, just call
+ lostpeer() to close the connection. whilst this might be
+ considered brutal, it's also extremely handy if you're
+ impatient or there's lossage at the remote end.
+
+ * add preformatted manual page
+
+ * fix --enable-editline
+
+Wed Oct 6 10:19:00 EST 1999 lukem
+
+ * released 1.0b4
+
+ * don't defining SIGINFO to SIGQUIT if the former doesn't exist; the

+
+ * rototill signal handling in the actual data xfer routines, and
+ specifically set SIGQUIT to psummary in each one, to override
+ editline's handler
+
+Tue Oct 5 23:48:29 EST 1999 lukem
+
+ * factor out SIGINFO setting into a handler that is always active
+ (but only prints out info if bytes > 0). only set the handler if
+ SIGINFO is defined
+
+ * hijack SIGQUIT to be the same as SIGINFO
+
+ * in {recv,send}request(), factor a lot of duplicated code out into
+ a `cleanup' section at the end
+
+ * rework shell() a bit
+
+ * enhancments from Marc Horowitz <marc at mit.edu> to improve
+ connection timeouts:
+ - implement xsignal_restart(), which only sets the SA_RESTART
+ flag if specifically requested
+ - xsignal() is now a wrapper to xsignal_restart(). INFO,
+ USR1, USR2 and WINCH are restartable, ALRM, INT, PIPE and
+ QUIT are not

+INSTALLATION INTRODUCTION
+-------------------------
+
+This file describes how to compile and install tnftp on your system.
+
+ ============================================
+ = =
+ = NOTE: You will need an ANSI C compiler. =
+ = =
+ ============================================
+
+
+For most systems, execute the following to compile and install tnftp:
+ ./configure
+ make
+ make install
+
+A preformatted manual page (src/ftp.cat1) is also installed.
+If you wish to install the source (src/ftp.1), ensure that your system
+has up-to-date mandoc macros, such as those that are shipped with groff.
+
+
+CONFIGURATION OPTIONS
+---------------------
+
+tnftp is configured using an `autoconf' generated `configure'
+script. `configure' supports the following options:
+
+* The standard `autoconf configure' options, including:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [/usr/local]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [same as prefix]
+ --srcdir=DIR find the sources in DIR [configure dir or ..]
+ BSD or GNU make may be required for this to work.
+
+* Specific options:
+ --enable-editcomplete Turn on command line editing and completion.
+ (default: enabled)
+ --enable-ipv6 Enable IPv6 support (if your OS supports it).
+ (default: enabled)
+ --disable-largefile omit support for large files
+ --with-socks enable support for (Dante) SOCKS5 proxy
+
+The following environment variables can be set to override various
+compiler related settings.
+ CC=compiler specify name of the C compiler (default: gcc or cc)
+ CFLAGS=flags specify flags to C compiler (default: -O -g or just -O)
+ LDFLAGS=flags specify flags to linker (default: none)
+
+This can be achieved with:
+ env CC="compiler" CFLAGS="flags" LDFLAGS="flags" ./configure
+

+WHAT IS TNFTP?
+--------------
+
+`tnftp' is a `port' of the NetBSD FTP client to other systems.
+See http://www.NetBSD.org/ for more details about NetBSD.
+
+tnftp was formerly known as `lukemftp'
+It was renamed to `tnftp' by Luke Mewburn in February 2003.
+
+The enhancements over the standard ftp client in 4.4BSD (and
+derivatives) include:
+ * command-line editing within ftp
+ * command-line fetching of URLS, including support for:
+ - http proxies (see $http_proxy, $ftp_proxy)
+ - authentication
+ * configurable prompt
+ * context sensitive command and filename completion
+ * dynamic progress bar
+ * feature negotiation extensions from RFC 2389
+ (see `feat' and `remopts')
+ * extensions to ftp from the IETF ftpext working group
+ (see `mlsd' and `mlst')
+ * IPv6 support (from the WIDE project)
+ * modification time preservation
+ * paging of local and remote files, and of directory listings
+ (see `lpage', `page', `pdir')
+ * passive mode support, with fallback to active mode
+ * retrieval of filenames listed in a given file (see `fget')
+ * `set option' override of ftp environment variables
+ * TIS Firewall Toolkit gate ftp proxy support (see `gate')
+ * transfer-rate throttling (see `-T', `rate')
+ * uploading of files on the command line (see `-u')
+ * (Dante) SOCKS5 support
+
+Previous features, currently disabled until a test system is available:
+ * SOCKS4 support
+
+

+.Sh DESCRIPTION
+.Nm
+is the user interface to the Internet standard File Transfer Protocol.
+The program allows a user to transfer files to and from a
+remote network site.
+.Pp
+The last five arguments will fetch a file using the
+.Tn FTP
+or
+.Tn HTTP
+protocols, or by direct copying, into the current directory.
+This is ideal for scripts.
+Refer to
+.Sx AUTO-FETCHING FILES
+below for more information.
+.Pp
+Options may be specified at the command line, or to the
+command interpreter.
+.Bl -tag -width Fl
+.It Fl 4
+Forces
+.Nm
+to only use IPv4 addresses.
+.It Fl 6
+Forces
+.Nm
+to only use IPv6 addresses.
+.It Fl A
+Force active mode ftp.
+By default,
+.Nm
+will try to use passive mode ftp and fall back to active mode
+if passive is not supported by the server.
+This option causes
+.Nm
+to always use an active connection.
+It is only useful for connecting to very old servers that do not
+implement passive mode properly.
+.It Fl a
+Causes
+.Nm
+to bypass normal login procedure, and use an anonymous login instead.
+.It Fl d
+Enables debugging.
+.It Fl e
+Disables command line editing.
+This is useful for Emacs ange-ftp mode.
+.It Fl f
+Forces a cache reload for transfers that go through the
+.Tn FTP
+or
+.Tn HTTP
+proxies.
+.It Fl g
+Disables file name globbing.
+.It Fl i
+Turns off interactive prompting during
+multiple file transfers.
+.It Fl N Ar netrc
+Use
+.Ar netrc
+instead of
+.Pa ~/.netrc .
+Refer to
+.Sx THE .netrc FILE
+for more information.
+.It Fl n
+Restrains
+.Nm
+from attempting
+.Dq auto-login
+upon initial connection for non auto-fetch transfers.
+If auto-login is enabled,
+.Nm
+will check the
+.Pa .netrc
+(see below) file in the user's home directory for an entry describing
+an account on the remote machine.
+If no entry exists,
+.Nm
+will prompt for the remote machine login name (default is the user
+identity on the local machine), and, if necessary, prompt for a password
+and an account with which to login.
+To override the auto-login for auto-fetch transfers, specify the
+username (and optionally, password) as appropriate.
+.It Fl o Ar output
+When auto-fetching files, save the contents in
+.Ar output .
+.Ar output
+is parsed according to the
+.Sx FILE NAMING CONVENTIONS
+below.
+If
+.Ar output
+is not
+.Sq -
+or doesn't start with
+.Sq \&| ,
+then only the first file specified will be retrieved into
+.Ar output ;
+all other files will be retrieved into the basename of their
+remote name.
+.It Fl P Ar port
+Sets the port number to
+.Ar port .
+.It Fl p
+Enable passive mode operation for use behind connection filtering firewalls.
+This option has been deprecated as
+.Nm
+now tries to use passive mode by default, falling back to active mode
+if the server does not support passive connections.
+.It Fl q Ar quittime
+Quit if the connection has stalled for
+.Ar quittime
+seconds.
+.It Fl R
+Restart all non-proxied auto-fetches.
+.It Fl r Ar wait
+Retry the connection attempt if it failed, pausing for
+.Ar wait
+seconds.
+.It Fl s Ar srcaddr
+Uses
+.Ar srcaddr
+as the local IP address for all connections.
+.It Fl t
+Enables packet tracing.
+.It Fl T Ar direction Ns , Ns Ar maximum Ns Oo , Ns Ar increment Oc
+Set the maximum transfer rate for
+.Ar direction
+to
+.Ar maximum
+bytes/second,
+and if specified, the increment to
+.Ar increment
+bytes/second.
+Refer to
+.Ic rate
+for more information.
+.It Fl u Ar URL file Op \&.\&.\&.
+Upload files on the command line to
+.Ar URL
+where
+.Ar URL
+is one of the ftp URL types as supported by auto-fetch
+(with an optional target filename for single file uploads), and
+.Ar file
+is one or more local files to be uploaded.
+.It Fl V
+Disable
+.Ic verbose
+and
+.Ic progress ,
+overriding the default of enabled when output is to a terminal.
+.It Fl v
+Enable
+.Ic verbose
+and
+.Ic progress .
+This is the default if output is to a terminal (and in the case of
+.Ic progress ,
+.Nm
+is the foreground process).
+Forces
+.Nm
+to show all responses from the remote server, as well
+as report on data transfer statistics.
+.El
+.Pp
+The client host with which
+.Nm
+is to communicate may be specified on the command line.
+If this is done,
+.Nm
+will immediately attempt to establish a connection to an
+.Tn FTP
+server on that host; otherwise,
+.Nm
+will enter its command interpreter and await instructions
+from the user.
+When
+.Nm
+is awaiting commands from the user the prompt
+.Ql ftp\*[Gt]
+is provided to the user.
+The following commands are recognized
+by
+.Nm ftp :
+.Bl -tag -width Ic
+.It Ic \&! Op Ar command Op Ar args
+Invoke an interactive shell on the local machine.
+If there are arguments, the first is taken to be a command to execute
+directly, with the rest of the arguments as its arguments.
+.It Ic \&$ Ar macro-name Op Ar args
+Execute the macro
+.Ar macro-name
+that was defined with the
+.Ic macdef
+command.
+Arguments are passed to the macro unglobbed.
+.It Ic account Op Ar passwd
+Supply a supplemental password required by a remote system for access
+to resources once a login has been successfully completed.
+If no argument is included, the user will be prompted for an account
+password in a non-echoing input mode.
+.It Ic append Ar local-file Op Ar remote-file
+Append a local file to a file on the remote machine.
+If
+.Ar remote-file
+is left unspecified, the local file name is used in naming the
+remote file after being altered by any
+.Ic ntrans
+or
+.Ic nmap
+setting.
+File transfer uses the current settings for
+.Ic type ,
+.Ic format ,
+.Ic mode ,
+and
+.Ic structure .
+.It Ic ascii
+Set the file transfer
+.Ic type
+to network
+.Tn ASCII .
+This is the default type.
+.It Ic bell
+Arrange that a bell be sounded after each file transfer
+command is completed.
+.It Ic binary
+Set the file transfer
+.Ic type
+to support binary image transfer.
+.It Ic bye
+Terminate the
+.Tn FTP
+session with the remote server
+and exit
+.Nm ftp .
+An end of file will also terminate the session and exit.
+.It Ic case
+Toggle remote computer file name case mapping during
+.Ic get ,
+.Ic mget
+and
+.Ic mput
+commands.
+When
+.Ic case
+is on (default is off), remote computer file names with all letters in
+upper case are written in the local directory with the letters mapped
+to lower case.
+.It Ic \&cd Ar remote-directory
+Change the working directory on the remote machine
+to
+.Ar remote-directory .
+.It Ic cdup
+Change the remote machine working directory to the parent of the
+current remote machine working directory.
+.It Ic chmod Ar mode remote-file
+Change the permission modes of the file
+.Ar remote-file
+on the remote
+system to
+.Ar mode .
+.It Ic close
+Terminate the
+.Tn FTP
+session with the remote server, and
+return to the command interpreter.
+Any defined macros are erased.
+.It Ic \&cr
+Toggle carriage return stripping during
+ascii type file retrieval.
+Records are denoted by a carriage return/linefeed sequence
+during ascii type file transfer.
+When
+.Ic \&cr
+is on (the default), carriage returns are stripped from this
+sequence to conform with the
+.Ux
+single linefeed record
+delimiter.
+Records on
+.Pf non\- Ns Ux
+remote systems may contain single linefeeds;
+when an ascii type transfer is made, these linefeeds may be
+distinguished from a record delimiter only when
+.Ic \&cr
+is off.
+.It Ic delete Ar remote-file
+Delete the file
+.Ar remote-file
+on the remote machine.
+.It Ic dir Op Ar remote-path Op Ar local-file
+Print a listing of the contents of a
+directory on the remote machine.
+The listing includes any system-dependent information that the server
+chooses to include; for example, most
+.Ux
+systems will produce
+output from the command
+.Ql ls \-l .
+If
+.Ar remote-path
+is left unspecified, the current working directory is used.
+If interactive prompting is on,
+.Nm
+will prompt the user to verify that the last argument is indeed the
+target local file for receiving
+.Ic dir
+output.
+If no local file is specified, or if
+.Ar local-file
+is
+.Sq Fl ,
+the output is sent to the terminal.
+.It Ic disconnect
+A synonym for
+.Ic close .
+.It Ic edit
+Toggle command line editing, and context sensitive command and file
+completion.
+This is automatically enabled if input is from a terminal, and
+disabled otherwise.
+.It Ic epsv epsv4 epsv6
+Toggle the use of the extended
+.Dv EPSV
+and
+.Dv EPRT
+commands on all IP, IPv4, and IPv6 connections respectively.
+First try
+.Dv EPSV /
+.Dv EPRT ,
+and then
+.Dv PASV /
+.Dv PORT .
+This is enabled by default.
+If an extended command fails then this option will be temporarily
+disabled for the duration of the current connection, or until
+.Ic epsv ,
+.Ic epsv4 ,
+or
+.Ic epsv6
+is executed again.
+.It Ic exit
+A synonym for
+.Ic bye .
+.It Ic features
+Display what features the remote server supports (using the
+.Dv FEAT
+command).
+.It Ic fget Ar localfile
+Retrieve the files listed in
+.Ar localfile ,
+which has one line per filename.
+.It Ic form Ar format
+Set the file transfer
+.Ic form
+to
+.Ar format .
+The default (and only supported)
+format is
+.Dq non-print .
+.It Ic ftp Ar host Op Ar port
+A synonym for
+.Ic open .
+.It Ic ftp_debug Op Ar ftp_debug-value
+Toggle debugging mode.
+If an optional
+.Ar ftp_debug-value
+is specified it is used to set the debugging level.
+When debugging is on,
+.Nm
+prints each command sent to the remote machine, preceded
+by the string
+.Ql \-\-\*[Gt] .
+.It Ic gate Op Ar host Op Ar port
+Toggle gate-ftp mode, which used to connect through the
+TIS FWTK and Gauntlet ftp proxies.
+This will not be permitted if the gate-ftp server hasn't been set
+(either explicitly by the user, or from the
+.Ev FTPSERVER
+environment variable).
+If
+.Ar host
+is given,
+then gate-ftp mode will be enabled, and the gate-ftp server will be set to
+.Ar host .
+If
+.Ar port
+is also given, that will be used as the port to connect to on the
+gate-ftp server.
+.It Ic get Ar remote-file Op Ar local-file
+Retrieve the
+.Ar remote-file
+and store it on the local machine.
+If the local
+file name is not specified, it is given the same
+name it has on the remote machine, subject to
+alteration by the current
+.Ic case ,
+.Ic ntrans ,
+and
+.Ic nmap
+settings.
+The current settings for
+.Ic type ,
+.Ic form ,
+.Ic mode ,
+and
+.Ic structure
+are used while transferring the file.
+.It Ic glob
+Toggle filename expansion for
+.Ic mdelete ,
+.Ic mget ,
+.Ic mput ,
+and
+.Ic mreget .
+If globbing is turned off with
+.Ic glob ,
+the file name arguments
+are taken literally and not expanded.
+Globbing for
+.Ic mput
+is done as in
+.Xr csh 1 .
+For
+.Ic mdelete ,
+.Ic mget ,
+and
+.Ic mreget ,
+each remote file name is expanded
+separately on the remote machine and the lists are not merged.
+Expansion of a directory name is likely to be
+different from expansion of the name of an ordinary file:
+the exact result depends on the foreign operating system and ftp server,
+and can be previewed by doing
+.Ql mls remote-files \-
+Note:
+.Ic mget ,
+.Ic mput
+and
+.Ic mreget
+are not meant to transfer
+entire directory subtrees of files.
+That can be done by
+transferring a
+.Xr tar 1
+archive of the subtree (in binary mode).
+.It Ic hash Op Ar size
+Toggle hash-sign
+.Pq Sq #
+printing for each data block transferred.
+The size of a data block defaults to 1024 bytes.
+This can be changed by specifying
+.Ar size
+in bytes.
+Enabling
+.Ic hash
+disables
+.Ic progress .
+.It Ic help Op Ar command
+Print an informative message about the meaning of
+.Ar command .

+.It Ic nlist Op Ar remote-path Op Ar local-file
+A synonym for
+.Ic ls .
+.It Ic nmap Op Ar inpattern outpattern
+Set or unset the filename mapping mechanism.
+If no arguments are specified, the filename mapping mechanism is unset.
+If arguments are specified, remote filenames are mapped during
+.Ic mput
+commands and
+.Ic put
+commands issued without a specified remote target filename.
+If arguments are specified, local filenames are mapped during
+.Ic mget
+commands and
+.Ic get
+commands issued without a specified local target filename.
+This command is useful when connecting to a
+.No non\- Ns Ux
+remote computer
+with different file naming conventions or practices.
+The mapping follows the pattern set by
+.Ar inpattern
+and
+.Ar outpattern .
+.Op Ar Inpattern
+is a template for incoming filenames (which may have already been
+processed according to the
+.Ic ntrans
+and
+.Ic case
+settings).
+Variable templating is accomplished by including the
+sequences
+.Dq $1 ,
+.Dq $2 ,
+\&...
+.Dq $9
+in
+.Ar inpattern .
+Use
+.Sq \e
+to prevent this special treatment of the
+.Sq $
+character.
+All other characters are treated literally, and are used to determine the
+.Ic nmap
+.Op Ar inpattern
+variable values.
+For example, given
+.Ar inpattern
+$1.$2 and the remote file name "mydata.data", $1 would have the value
+"mydata", and $2 would have the value "data".
+The
+.Ar outpattern
+determines the resulting mapped filename.
+The sequences
+.Dq $1 ,
+.Dq $2 ,
+\&...
+.Dq $9
+are replaced by any value resulting from the
+.Ar inpattern
+template.
+The sequence
+.Dq $0
+is replaced by the original filename.
+Additionally, the sequence
+.Dq Op Ar seq1 , Ar seq2
+is replaced by
+.Op Ar seq1
+if
+.Ar seq1
+is not a null string; otherwise it is replaced by
+.Ar seq2 .
+For example, the command
+.Pp
+.Bd -literal -offset indent -compact
+nmap $1.$2.$3 [$1,$2].[$2,file]
+.Ed
+.Pp
+would yield
+the output filename "myfile.data" for input filenames "myfile.data" and
+"myfile.data.old", "myfile.file" for the input filename "myfile", and
+"myfile.myfile" for the input filename ".myfile".
+Spaces may be included in
+.Ar outpattern ,
+as in the example:
+.Dl nmap $1 sed "s/ *$//" \*[Gt] $1
+Use the
+.Sq \e
+character to prevent special treatment
+of the
+.Sq $ ,
+.Sq \&[ ,
+.Sq \&] ,
+and
+.Sq \&,
+characters.
+.It Ic ntrans Op Ar inchars Op Ar outchars
+Set or unset the filename character translation mechanism.
+If no arguments are specified, the filename character
+translation mechanism is unset.
+If arguments are specified, characters in
+remote filenames are translated during
+.Ic mput
+commands and
+.Ic put
+commands issued without a specified remote target filename.
+If arguments are specified, characters in
+local filenames are translated during
+.Ic mget
+commands and
+.Ic get
+commands issued without a specified local target filename.
+This command is useful when connecting to a
+.No non\- Ns Ux
+remote computer
+with different file naming conventions or practices.
+Characters in a filename matching a character in
+.Ar inchars
+are replaced with the corresponding character in
+.Ar outchars .
+If the character's position in
+.Ar inchars
+is longer than the length of
+.Ar outchars ,
+the character is deleted from the file name.
+.It Ic open Ar host Op Ar port
+Establish a connection to the specified
+.Ar host
+.Tn FTP
+server.
+An optional port number may be supplied,
+in which case,
+.Nm
+will attempt to contact an
+.Tn FTP
+server at that port.
+If the
+.Ic "set auto-login"
+option is on (default),
+.Nm
+will also attempt to automatically log the user in to

+server (see below).
+.It Ic page Ar file
+Retrieve

+option.
+.It Ic passive Op Cm auto
+Toggle passive mode (if no arguments are given).
+If

+is set to
+.Sq auto .
+If passive mode is turned on (default),
+.Nm
+will send a
+.Dv PASV
+command for all data connections instead of a
+.Dv PORT
+command.
+The
+.Dv PASV
+command requests that the remote server open a port for the data connection
+and return the address of that port.
+The remote server listens on that port and the client connects to it.
+When using the more traditional
+.Dv PORT
+command, the client listens on a port and sends that address to the remote
+server, who connects back to it.
+Passive mode is useful when using
+.Nm
+through a gateway router or host that controls the directionality of
+traffic.
+(Note that though
+.Tn FTP
+servers are required to support the
+.Dv PASV
+command by
+.Li RFC1123 ,

+.It Ic proxy Ar ftp-command
+Execute an ftp command on a secondary control connection.
+This command allows simultaneous connection to two remote

+The above interpretation has the following consequences:
+.Bl -bullet
+.It
+The path is interpreted relative to the
+default login directory of the specified user or of the
+.Sq anonymous
+user.
+If the
+.Pa /
+directory is required, use a leading path of
+.Dq %2F .
+If a user's home directory is required (and the remote server supports
+the syntax), use a leading path of
+.Dq %7Euser/ .
+For example, to retrieve
+.Pa /etc/motd
+from
+.Sq localhost
+as the user
+.Sq myname
+with the password
+.Sq mypass ,
+use
+.Dq ftp://myname:mypass@localhost/%2fetc/motd
+.It
+The exact
+.Ic cd
+and
+.Ic get
+commands can be controlled by careful choice of
+where to use
+.Sq /
+and where to use
+.Sq %2F
+(or
+.Sq %2f ) .
+For example, the following URLs correspond to the
+equivalents of the indicated commands:
+.Bl -tag -width "ftp://host/%2Fdir1%2Fdir2%2Ffile"
+.It ftp://host/dir1/dir2/file
+.Dq "cd dir1" ,

+.El
+.Pp
+Unless noted otherwise above, and
+.Fl o Ar output
+is not given, the file is stored in the current directory as the
+.Xr basename 1
+of
+.Ar path .
+Note that if a
+.Tn HTTP
+redirect is received, the fetch is retried using the new target URL
+supplied by the server, with a corresponding new
+.Ar path .
+Using an explicit
+.Fl o Ar output
+is recommended, to avoid writing to unexpected file names.
+.Pp
+If a classic format or an
+.Tn FTP
+URL format has a trailing
+.Sq /
+or an empty
+.Ar path
+component, then
+.Nm
+will connect to the site and
+.Ic cd
+to the directory given as the path, and leave the user in interactive
+mode ready for further input.
+This will not work if
+.Ic "set ftp_proxy"
+is being used.
+.Pp
+Direct
+.Tn HTTP

+transfers use HTTP 1.0.
+.Pp
+If
+.Fl R
+is given, all auto-fetches that don't go via the
+.Tn FTP
+or
+.Tn HTTP
+proxies will be restarted.
+For
+.Tn FTP ,
+this is implemented by using
+.Nm reget
+instead of
+.Nm get .
+For
+.Tn HTTP ,
+this is implemented by using the
+.Sq "Range: bytes="
+.Tn "HTTP/1.1"
+directive.
+.Pp
+If WWW or proxy WWW authentication is required, you will be prompted
+to enter a username and password to authenticate with.
+.Pp
+When specifying IPv6 numeric addresses in a URL, you need to
+surround the address in square brackets.
+E.g.:
+.Dq ftp://[::1]:21/ .
+This is because colons are used in IPv6 numeric address as well as
+being the separator for the port number.
+.Sh ABORTING A FILE TRANSFER
+To abort a file transfer, use the terminal interrupt key
+(usually Ctrl-C).
+Sending transfers will be immediately halted.
+Receiving transfers will be halted by sending an
+.Tn FTP
+protocol
+.Dv ABOR
+command to the remote server, and discarding any further data received.
+The speed at which this is accomplished depends upon the remote
+server's support for
+.Dv ABOR
+processing.
+If the remote server does not support the
+.Dv ABOR
+command, the prompt will not appear until the remote server has completed
+sending the requested file.
+.Pp
+If the terminal interrupt key sequence is used whilst
+.Nm
+is awaiting a reply from the remote server for the ABOR processing,
+then the connection will be closed.
+This is different from the traditional behaviour (which ignores the
+terminal interrupt during this phase), but is considered more useful.
+.Sh FILE NAMING CONVENTIONS
+Files specified as arguments to
+.Nm
+commands are processed according to the following rules.
+.Bl -enum
+.It
+If the file name
+.Sq Fl
+is specified, the
+.Ar stdin
+(for reading) or
+.Ar stdout
+(for writing) is used.
+.It
+If the first character of the file name is
+.Sq \&| ,
+the
+remainder of the argument is interpreted as a shell command.
+.Nm
+then forks a shell, using
+.Xr popen 3
+with the argument supplied, and reads (writes) from the stdout
+(stdin).
+If the shell command includes spaces, the argument
+must be quoted; e.g.
+.Dq Qq Li \&| ls\ \-lt .
+A particularly
+useful example of this mechanism is:
+.Dq Li dir \&"\&" \&|more .
+.It
+Failing the above checks, if
+.Dq globbing
+is enabled, local file names are expanded according to the rules
+used in the
+.Xr csh 1 ;
+see the
+.Ic glob
+command.
+If the
+.Nm
+command expects a single local file (e.g.
+.Ic put ) ,
+only the first filename generated by the "globbing" operation is used.
+.It
+For
+.Ic mget
+commands and
+.Ic get
+commands with unspecified local file names, the local filename is
+the remote filename, which may be altered by a
+.Ic case ,
+.Ic ntrans ,
+or
+.Ic nmap
+setting.
+The resulting filename may then be altered if
+.Ic runique
+is on.
+.It
+For
+.Ic mput
+commands and
+.Ic put
+commands with unspecified remote file names, the remote filename is
+the local filename, which may be altered by a
+.Ic ntrans
+or
+.Ic nmap
+setting.
+The resulting filename may then be altered by the remote server if
+.Ic sunique
+is on.
+.El
+.Sh FILE TRANSFER PARAMETERS
+The
+.Tn FTP
+specification specifies many parameters which may affect a file transfer.
+The
+.Ic type
+may be one of
+.Dq ascii ,
+.Dq image
+(binary),
+.Dq ebcdic ,
+and
+.Dq local byte size
+(for
+.Tn PDP Ns -10's
+and
+.Tn PDP Ns -20's
+mostly).
+.Nm
+supports the ascii and image types of file transfer,
+plus local byte size 8 for
+.Ic tenex
+mode transfers.
+.Pp
+.Nm
+supports only the default values for the remaining
+file transfer parameters:
+.Ic mode ,
+.Ic form ,
+and
+.Ic struct .
+.Sh THE .netrc FILE
+The
+.Pa .netrc
+file contains login and initialization information
+used by the auto-login process.
+It resides in the user's home directory,
+unless overridden with the
+.Fl N Ar netrc
+option, or specified in the
+.Ev NETRC
+environment variable.
+The following tokens are recognized; they may be separated by spaces,
+tabs, or new-lines:
+.Bl -tag -width password
+.It Ic machine Ar name
+Identify a remote machine
+.Ar name .
+The auto-login process searches the
+.Pa .netrc
+file for a
+.Ic machine
+token that matches the remote machine specified on the
+.Nm
+command line or as an
+.Ic open
+command argument.
+Once a match is made, the subsequent
+.Pa .netrc
+tokens are processed,
+stopping when the end of file is reached or another
+.Ic machine
+or a
+.Ic default
+token is encountered.
+.It Ic default
+This is the same as
+.Ic machine
+.Ar name
+except that
+.Ic default
+matches any name.
+There can be only one
+.Ic default
+token, and it must be after all
+.Ic machine
+tokens.
+This is normally used as:
+.Pp
+.Dl default login anonymous password user at site
+.Pp
+thereby giving the user an automatic anonymous
+.Tn FTP
+login to
+machines not specified in
+.Pa .netrc .
+This can be overridden
+by using the
+.Fl n
+flag to disable auto-login.
+.It Ic login Ar name
+Identify a user on the remote machine.
+If this token is present, the auto-login process will initiate
+a login using the specified
+.Ar name .
+.It Ic password Ar string
+Supply a password.
+If this token is present, the auto-login process will supply the
+specified string if the remote server requires a password as part
+of the login process.
+Note that if this token is present in the
+.Pa .netrc
+file for any user other
+than
+.Ar anonymous ,
+.Nm
+will abort the auto-login process if the
+.Pa .netrc
+is readable by
+anyone besides the user.
+.It Ic account Ar string
+Supply an additional account password.
+If this token is present, the auto-login process will supply the
+specified string if the remote server requires an additional
+account password, or the auto-login process will initiate an
+.Dv ACCT
+command if it does not.
+.It Ic macdef Ar name
+Define a macro.
+This token functions like the
+.Nm
+.Ic macdef
+command functions.
+A macro is defined with the specified name; its contents begin with the
+next
+.Pa .netrc
+line and continue until a blank line (consecutive new-line
+characters) is encountered.
+Like the other tokens in the
+.Pa .netrc
+file, a
+.Ic macdef
+is applicable only to the
+.Ic machine
+definition preceding it.
+A
+.Ic macdef
+entry cannot be used by multiple
+.Ic machine
+definitions; rather, it must be defined following each
+.Ic machine
+it is intended to be used with.
+If a macro named
+.Ic init
+is defined, it is automatically executed as the last step in the
+auto-login process.
+For example,
+.Bd -literal -offset indent
+default
+macdef init
+epsv4 off
+.Ed
+.Pp
+followed by a blank line.
+.El
+.Sh COMMAND LINE EDITING
+.Nm
+supports interactive command line editing, via the
+.Xr editline 3
+library.
+It is enabled with the
+.Ic edit
+command, and is enabled by default if input is from a tty.
+Previous lines can be recalled and edited with the arrow keys,
+and other GNU Emacs-style editing keys may be used as well.
+.Pp
+The
+.Xr editline 3
+library is configured with a
+.Pa .editrc
+file - refer to
+.Xr editrc 5
+for more information.
+.Pp
+An extra key binding is available to
+.Nm
+to provide context sensitive command and filename completion
+(including remote file completion).
+To use this, bind a key to the
+.Xr editline 3
+command
+.Ic ftp-complete .
+By default, this is bound to the TAB key.
+.Sh COMMAND LINE PROMPT
+By default,
+.Nm
+displays a command line prompt of
+.Dq "ftp\*[Gt] "
+to the user.
+This can be changed with the
+.Ic "set prompt"
+command.
+.Pp
+A prompt can be displayed on the right side of the screen (after the
+command input) with the
+.Ic "set rprompt"
+command.
+.Pp
+The following formatting sequences are replaced by the given
+information:
+.Bl -tag -width "%% " -offset indent
+.It Li \&%/
+The current remote working directory.
+.\" %c[[0]n], %.[[0]n]
+.It \&%c Ns Oo Oo Li 0 Oc Ns Ar n Oc , Ns Li \&%. Ns Oo Oo Li 0 Oc Ns Ar n Oc
+The trailing component of the current remote working directory, or

+Each entry may have an optional trailing ":port", which restricts
+the matching to connections to that port.
+.El
+.Sh EXTENDED PASSIVE MODE AND FIREWALLS
+Some firewall configurations do not allow
+.Nm
+to use extended passive mode.
+If you find that even a simple
+.Ic ls
+appears to hang after printing a message such as this:
+.Pp
+.Dl 229 Entering Extended Passive Mode (|||58551|)
+.Pp
+then you will need to disable extended passive mode with

+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Bx 4.2 .
+.Pp
+Various features such as command line editing, context sensitive
+command and file completion, dynamic progress bar, automatic
+fetching of files and URLs, modification time preservation,
+transfer rate throttling, configurable command line prompt,
+and other enhancements over the standard
+.Bx
+.Nm
+were implemented in
+.Nx 1.3
+and later releases
+by
+.An Luke Mewburn
+.Aq lukem at NetBSD.org .
+.Pp
+IPv6 support was added by the WIDE/KAME project
+(but may not be present in all non-NetBSD versions of this program, depending
+if the operating system supports IPv6 in a similar manner to KAME).
+.Sh BUGS
+Correct execution of many commands depends upon proper behavior
+by the remote server.
+.Pp
+An error in the treatment of carriage returns
+in the
+.Bx 4.2
+ascii-mode transfer code
+has been corrected.
+This correction may result in incorrect transfers of binary files
+to and from
+.Bx 4.2
+servers using the ascii type.
+Avoid this problem by using the binary image type.
+.Pp
+.Nm
+assumes that all IPv4 mapped addresses
+.Po
+IPv6 addresses with a form like
+.Li ::ffff:10.1.1.1
+.Pc
+indicate IPv4 destinations which can be handled by
+.Dv AF_INET
+sockets.
+However, in certain IPv6 network configurations, this assumption is not true.
+In such an environment, IPv4 mapped addresses must be passed to
+.Dv AF_INET6
+sockets directly.
+For example, if your site uses a SIIT translator for IPv6-to-IPv4 translation,
+.Nm
+is unable to support your configuration.

+Current Items
+-------------
+
+autoconf test for HAVE_DECL_GETADDRINFO if providing getaddrinfo() override.
+(required for UnixWare 7.1.1)
+
+Interix may need hack to fix detection of getpgrp() void args.
+(See pkgsrc/net/tnftp/files/src/progressbar.c 1.2)
+
+Old Items
+---------
+
+add locale autoconf checks
+
+in configure, check for ansi c compiler and barf if it fails
+
+check if we need #defines for memcpy() et al
+
+possibly install editline.3 and editrc.5
+
+system specific tests (to remove need for manual intervention):
+- sunos4
+ LIBS+= -lresolv
