NAME

ggatec – GEOM Gate network client and control utility

CONTENTS

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 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/acd0
server# ggated

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