It listens to all traffic on an ethernet (or PPP) interface,
|
||
|
|
looking for special "knock" sequences of port-hits. A client
|
||
|
|
makes these port-hits by sending a TCP (or UDP) packet to a
|
||
|
|
port on the server. This port need not be open -- since
|
||
|
|
knockd listens at the link-layer level, it sees all traffic
|
||
|
|
even if it's destined for a closed port. When the server
|
||
|
|
detects a specific sequence of port-hits, it runs a command
|
||
|
|
defined in its configuration file. This can be used to open
|
||
|
|
up holes in a firewall for quick access.
