UnderNet Proxyscanner


Due to the overwhelming abuse of misconfigured Wingate, Socks and Proxy servers being exploited daily, the UnderNet network is now checking all users upon connection to any of the UnderNet IRC Servers.
This check is ONLY DONE if a user attempts to establish a connection to an UnderNet IRC server.
This should not be considered an attack on your system.
Be aware that this sort of connection to your system is probably common if you use services such as free IRC networks, game servers, etc...
If you do not desire this type of check to occur, then simply block access to the UnderNet network servers.
Connection to and use of the Undernet.org IRC Network is conditional upon acceptance of any and all applicable policies of the individual servers that make up the Undernet as well as acceptance of the Undernet.org Acceptable Use Policy and its Indemnify and Hold Harmless clause.
