fwknop

'fwknop' implements an authorization scheme that requires only a single encrypted packet to communicate various pieces of information, including desired access through a Netfilter policy and/or specific commands to execute on the target system. Its main use is to protect services such as SSH with an additional layer of security, which makies exploitation of vulnerabilities much more difficult. The authorization server works by passively monitoring authorization packets via libpcap.
