NGHOOK(8)

NAME
nghook - connect to a netgraph(4) node

SYNOPSIS
nghook [-a] [-d] path [hookname]

DESCRIPTION
nghook creates a ng_socket(4) socket type node and connects it to hook hookname of the node found at path. If hookname is omitted, “debug” is assumed.

At this point all data written to standard input is sent to the node and all data received from the node is relayed to standard output.

The options are as follows:

-a  Output each read packet in ASCII.

-d  Increase the debugging verbosity level.

SEE ALSO
netgraph(3), netgraph(4), ngctl(8)

HISTORY
The netgraph system was designed and first implemented at Whistle Communications, Inc. in a version of FreeBSD 2.2 customized for the Whistle InterJet.

BUGS
Although all input is read in unbuffered mode, there's no way to control the packetization of the input.
