fwknop_serv8
Fwknop server for the tor network.
Overview
fwknop_serv is a simplisitc TCP server that is only used if SPA packets are sent over the TOR anonymizing network (http://www.torproject.org). Use of this server results in bidirectional communication, so it technically breaks the usual unidirectional nature of the SPA protocol; More information can be found at the following : url http://www.cipherdyne.org/fwknop/docs/talks/dc14_fwknop_slides.pdf.
