NAME

ggatec —

GEOM Gate network client and control utility

SYNOPSIS

ggatec create [-n] [-v] [-o ro | wo | rw] [-p port] [-q queue_size] [-R rcvbuf] [-S sndbuf] [-s sectorsize] [-t timeout] [-u unit] host path

ggatec rescue [-n] [-v] [-o ro | wo | rw] [-p port] [-R rcvbuf] [-S sndbuf] -u unit host path

ggatec destroy [-f] -u unit

ggatec list [-v] [-u unit]

DESCRIPTION

The ggatec utility is a network client for the GEOM Gate class. It is responsible for the creation of ggate devices and forwarding I/O requests between the

GEOM
  Gate

kernel subsystem and the ggated(8) network daemon. Available commands:

create: Connect to a ggated(8) daemon on the specified host and create a ggate provider for the specified remote file or device.
rescue: Create a new connection after the ggatec process has died or been killed. The new connection to the ggated(8) daemon handles 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 permissions 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 the device, or set to 512 bytes for files.
-t timeout: Number of seconds to wait before an I/O request will be canceled. Default is 0, which means no timeout.
-u unit: Unit number to use.
-v: Do not fork, run in foreground and print debug information on standard output.
host: Remote host to connect to.
path: Path to a regular file or device.

EXIT STATUS

Exit status is 0 on success, or 1 if the command fails. To get details about the failure, ggatec should be called with the -v option.

EXAMPLES

Use a CD-ROM device on a remote host.

server# cat /etc/gg.exports
client RO /dev/cd0
server# ggated

client# ggatec create -o ro server /dev/cd0
ggate0
client# mount_cd9660 /dev/ggate0 /cdrom
