knock (net/knock) Add to my watchlist

A port-knocking implementation

knockd is a port-knock server. 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.
