If you don't want to use squidguard (or another filtering proxy) in addition to squid, you can use some of it's blacklists and load it directly on squid with an url_regex, as long as you don't filter much. I remember that some of the free blacklists had a "chat" category, so you may want to use one of those to start, then add to it as needed. Beware though, Squid slows down quite a bit when using big url_regexes 2009/4/23 Amos Jeffries <squid3@xxxxxxxxxxxxx>: > Jorge Bastos wrote: >> >> Hi guys, >> >> I'm starting to investigate on how to block a plague, that is the web >> messengers. >> There's every day more web messengers available, and it's almost >> impossible >> to be adding then as a iptables rule to block them, or in Squid. >> Is there a way to block this in squid, that all get blocked? >> >> Jorge, >> > > It's only a plague if you are not billing clients for their bandwidth usage > :) > > http://wiki.squid-cache.org/ConfigExamples/Chat > > If you know of other clients that go through Squid and can be identified, > please let me know what and how the ID is done. > > Amos > -- > Please be using > Current Stable Squid 2.7.STABLE6 or 3.0.STABLE14 > Current Beta Squid 3.1.0.7 > -- Those unforgettable memories for them I live Omoikane, Martian Successor Nadesico
