67.Sh DESCRIPTION
68The
69.Nm
70utility is a network client for the GEOM Gate class.
71It is responsible for the creation of
72.Nm ggate
73devices and forwarding I/O requests between the
74.Nm GEOM Gate
75kernel subsystem and the
76.Xr ggated 8
77network daemon.
78Available commands:
79.Bl -tag -width ".Cm destroy"
80.It Cm create
81Connect to a
82.Xr ggated 8
83daemon on the specified host and create a
84.Nm ggate
85provider for the specified remote file or device.
86.It Cm rescue
87Create a new connection after the
88.Nm
89process has died or been killed.
90The new connection to the
91.Xr ggated 8
92daemon handles pending and future requests.
93.It Cm destroy
94Destroy the given
95.Nm ggate
96provider.
97.It Cm list
98List
99.Nm ggate
100providers.
101.El
102.Pp
103Available options:
104.Bl -tag -width ".Fl s Cm ro | wo | rw"
105.It Fl f
106Forcibly destroy
107.Nm ggate
108provider (cancels all pending requests).

110Do not use
111.Dv TCP_NODELAY
112option on TCP sockets.
113.It Fl o Cm ro | wo | rw
114Specify permissions to use when opening the file or device: read-only
115.Pq Cm ro ,
116write-only
117.Pq Cm wo ,
118or read-write
119.Pq Cm rw .
120Default is

126Number of pending I/O requests that can be queued before they will
127start to be canceled.
128Default is 1024.
129.It Fl R Ar rcvbuf
130Size of receive buffer to use.
131Default is 131072 (128kB).
132.It Fl S Ar sndbuf
133Size of send buffer to use.
134Default is 131072 (128kB).
135.It Fl s Ar sectorsize
136Sector size for
137.Nm ggate
138provider.
139If not specified, it is taken from the device, or set to 512 bytes for files.
140.It Fl t Ar timeout
141Number of seconds to wait before an I/O request will be canceled.
