fwknop-gui - 1.3+dfsg-1+b2 main

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.
.
Fwknop GUI is a graphical user interface integrated with an Fwknop
client that provides the ability to send SPA packets to a remote
Fwknop server, as well as a front-end for creating and managing
client configurations for multiple Fwknop servers.
.
It supports exporting saved configuration data to a QR code format
readable by the Android client, as well as to the .fwknoprc format
readable by the command line client.
