libfko-doc binary package in Ubuntu Mantic ppc64el

 The FireWall KNock OPerator implements an authorization scheme called
 Single Packet Authorization (SPA), based on Netfilter and libpcap.
 .
 Its main application is to protect services such as OpenSSH with
 an additional layer of security in order to make the exploitation of
 vulnerabilities (both 0-day and unpatched code) much more difficult.
 .
 The authorization server passively listens for authorization packets via
 libpcap, so there is no service listening for network connections on the
 traditional port. Access to a protected service is only granted after a
 valid encrypted and non-replayed packet is detected.
 .
 This package provides the library documentation.
