CAMPAGNOL RDV SERVER

NAME

campagnol_rdv - Decentralized VPN over UDP tunneling, RDV server

SYNOPSIS

campagnol_rdv [−dghvV] [-p port] [-m n_clients]

DESCRIPTION

Campagnol is a distributed IP-based VPN software able to open new connections through NATs or firewalls without any configuration. It uses UDP for the transport layer and utilizes tunneling and encryption (with DTLS).

This software is the rendezvous server of the VPN. It is used to register each participant of the VPN and is needed for the UDP hole punching. It regularly exchanges keepalive messages with each registered clients in order to maintain the contexts of the connections in the involved NATs and firewalls.

The server opens a UDP socket to communicate with the clients. The default port is 57888.
