SYNOPSIS

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

DESCRIPTION

The 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 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.
-u unit: Unit number to use.
-v: Do not fork, run in foreground and print debug informations on standard output.
host: Remote host to connect to.
path: Path to a regular file or device.
