It is responsible for creation of .Nm ggate devices and forwarding I/O requests between .Nm geom_gate.ko kernel module and .Xr ggated 8 network daemon. Available commands: .Bl -tag -width ".Cm destroy" .It Cm create Connect to given .Xr ggated 8 daemon and create a .Nm ggate provider related to the given remote file or device. .It Cm rescue If .Nm process died/has been killed, you can save situation with this command, which creates new connection to the .Xr ggated 8 daemon and will handle pending and future requests. .It Cm destroy Destroy the given .Nm ggate provider. .It Cm list List .Nm ggate providers. .El .Pp Available options: .Bl -tag -width ".Fl s Cm ro | wo | rw" .It Fl f Forcibly destroy .Nm ggate provider (cancels all pending requests). .It Fl n Do not use .Dv TCP_NODELAY option on TCP sockets. .It Fl o Cm ro | wo | rw Specify permission to use when opening the file or device: read-only .Pq Cm ro , write-only .Pq Cm wo , or read-write .Pq Cm rw . Default is .Cm rw . .It Fl p Ar port Port to connect to on the remote host. Default is 3080. .It Fl q Ar queue_size Number of pending I/O requests that can be queued before they will start to be canceled. Default is 1024. .It Fl R Ar rcvbuf Size of receive buffer to use. Default is 131072 (128kB). .It Fl S Ar sndbuf Size of send buffer to use. Default is 131072 (128kB). .It Fl s Ar sectorsize Sector size for .Nm ggate provider. If not specified, it is taken from device, or set to 512 bytes for files. .It Fl t Ar timeout Number of seconds to wait before an I/O request will be canceled. 0 means no timeout. Default is 0. .It Fl u Ar unit Unit number to use. .It Fl v Do not fork, run in foreground and print debug informations on standard output. .It Ar host Remote host to connect to. .It Ar path Path to a regular file or device. .El .Sh EXIT STATUS Exit status is 0 on success, or 1 if the command fails. To get details about the failure, .Nm should be called with the .Fl v option. .Sh EXAMPLES Made use of CD-ROM device from remote host. .Bd -literal -offset indent 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 .Ed .Sh SEE ALSO .Xr geom 4 , .Xr ggated 8 , .Xr ggatel 8 , .Xr mount_cd9660 8 .Sh AUTHORS The .Nm utility as well as this manual page was written by .An Pawel Jakub Dawidek Aq pjd@FreeBSD.org .
