[ubuntu] problem using xchat through squid

view story

http://ubuntuforums.org – I am having a problem with squid proxy server and xchat as well as kvirc. This is the error I see in xchat and kvirc when it is trying to connect to proxyip: port HTTP/1.0 403 Forbidden Proxy traversal failed. The same proxy server information works just fine when I set it up in the web browser. sudo dpkg -l | grep squid ii squid-langpack 20100628-1 Localized error pages for Squid ii squid3 3.1.6-1.2+squeeze3 A full featured Web Proxy cache (HTTP proxy) ii squid3-common 3.1.6-1.2+squeeze (Hardware)
