Summary: A port-knocking server |
It listens to all traffic on an ethernet (or PPP) interface, looking for special "knock" sequences of port-hits. A client (package knock) 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.

Pcap recommends we not use zero. - Changes from version 0.6 * Cleanup: Don't null-check before free * Cleanup: Consolidate flag-check logic * Accept single-knock sequences * Introduce a 'target' configuration directive, enabling knockd to react to connect attempts to a target host.
