.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility creates a new netgraph node of type
|
|
.Em socket
|
|
which can be used to issue netgraph commands.
|
|
If no

|
flag is given, no
|
|
command is supplied on the command line, and standard input is a tty,
|
|
.Nm
|
|
will enter interactive mode.
|
|
Otherwise

|
.Nm

|
.Pp
|
|
Nodes can be created, removed, joined together, etc.
|
|
.Tn ASCII
|
|
formatted control messages can be sent to any node if that node
|
|
supports binary/ASCII control message conversion.
|
|
.Pp
|
|
In interactive mode,
|
|
.Nm
|
|
will display any control messages and data packets received by the socket node.
|
|
In the case of control messages, the message arguments are displayed in
|
|
.Tn ASCII
|
|
form if the originating node supports conversion.
