67.Sh DESCRIPTION
68The
69.Nm
70utility is a network client for GEOM Gate class.
71It is responsible for creation of
72.Nm ggate
73devices and forwarding I/O requests between
74.Nm geom_gate.ko
75kernel module and
76.Xr ggated 8
77network daemon.
78Available commands:
79.Bl -tag -width ".Cm destroy"
80.It Cm create
81Connect to given
82.Xr ggated 8
83daemon and create a
84.Nm ggate
85provider related to the given remote file or device.
86.It Cm attach
87Attach a worker process to an existing
88.Nm ggate
89provider (create a new connection to the

91daemon).
92.It Cm destroy
93Destroy the given
94.Nm ggate
95provider.
