DESCRIPTION

The ggatec utility is a network client for GEOM Gate class. It is responsible for creation of ggate devices and forwarding I/O requests between geom_gate.ko kernel module and ggated(8) network daemon. Available commands:

create

Connect to given ggated(8) daemon and create a ggate provider related to the given remote file or device.

rescue

If ggatec process died/has been killed, you can save situation with this command, which creates new connection to the ggated(8) daemon and will handle pending and future requests.

destroy

Destroy the given ggate provider.

list

List ggate providers.

Available options:

−f

Forcibly destroy ggate provider (cancels all pending requests).

−n

Do not use TCP_NODELAY option on TCP sockets.

−o ro | wo | rw

Specify permission to use when opening the file or device: read-only (ro), write-only (wo), or read-write (rw). Default is rw.

−p port

Port to connect to on the remote host. Default is 3080.

−q queue_size

Number of pending I/O requests that can be queued before they will start to be canceled. Default is 1024.

−R rcvbuf

Size of receive buffer to use. Default is 131072 (128kB).

−S sndbuf

Size of send buffer to use. Default is 131072 (128kB).

−s sectorsize

Sector size for ggate provider. If not specified, it is taken from device, or set to 512 bytes for files.

−t timeout

Number of seconds to wait before an I/O request will be canceled. 0 means no timeout. Default is 0.

server# cat /etc/gg.exports
client RO /dev/acd0
server# ggated

client# ggatec create -o ro server /dev/acd0
ggate0
client# mount_cd9660 /dev/ggate0 /cdrom
