NAME

SYNOPSIS

DESCRIPTION

Nodes can be created, removed, joined together, etc. ASCII formatted control messages can be sent to any node if that node supports binary/ASCII control message conversion.

In interactive mode, ngctl 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 ASCII form if the originating node supports conversion.

The options are as follows:

-f nodeinfo

Read commands from the named file. A single dash represents the standard input. Blank lines and lines starting with a “#” are ignored.

-n nodename

Assign nodename to the newly created netgraph node. The default name is ngctlXXX where XXX is the process ID number.

-d

Increase the debugging verbosity level.
