The server part (package knockd) listens to all traffic on an ethernet (or PPP) interface, looking for special "knock" sequences of port hits. This client makes these port hits by sending a TCP (or UDP) packet to a port on the server. This port does not need to be open. Since knockd listens at the link-layer level, it sees all traffic even if it is 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.

    Changelog

    2015-12-01 - p.drouand@gmail.com - Update to version 0.7 * Document the 'target' configuration directive. * Merging OS-specific networking code to reduce LOCs and the sea of #ifdefs. * Added 50ms timeout to pcap_open_live() to reduce CPU usage on network-heavy hosts. 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.
