PAM_ECHO(8) MidnightBSD System Manager’s Manual PAM_ECHO(8)


pam_echo — Echo PAM module


[service-name] module-type control-flag pam_echo [arguments]


The echo service module for PAM displays its arguments to the user, separated by spaces, using the current conversation function.

If the % character occurs anywhere in the arguments to pam_echo, it is assumed to introduce one of the following escape sequences:


The name of the host on which the client runs (PAM_RHOST).


The current service name (PAM_SERVICE).


The name of the controlling tty (PAM_TTY).


The applicant’s user name (PAM_RUSER).


The target account’s user name (PAM_USER).

Any other two-character sequence beginning with % expands to the character following the % character.


pam.conf(5), pam(8)


The pam_echo module and this manual page were developed for the FreeBSD Project by ThinkSec AS and NAI Labs, the Security Research Division of Network Associates, Inc. under DARPA/SPAWAR contract N66001-01-C-8035 (‘‘CBOSS’’), as part of the DARPA CHATS research program.
