Setting up Pidgin for Google Talk behind an http proxy (web proxy / corporate firewall)
I use Google Talk at work mainly to post to social networks (army.twit.tv, identi.ca, twitter.com, yammer.com). It is possible to receive notification using Google Talk (which is just a Jabber/XMPP instance), but I find that too intrusive to what little work I get done.
-
Run pidgin (if not already) and select Accounts->Manage
-
Select Add to add another account:
-
Select XMPP for the protocol type:
-
Fill out the form as follows with gmail/gtalk username & password; domain is gmail.com; Resource is (optionally) Work:
-
Click advanced button. Select old (port 5223) SSL. Select 443 for port number. Server is talk.google.com. Fill out http proxy (for example, wwwgate0.example.com, port 1080) & http-proxy username & password (not likely the same as your gmail username/password):
This works because http proxies generally allow ports 80 (http) and port 443 (SSL/https) through. They generally disallow other ports. Luckily, google’s jabber server (talk.google.com) accepts connections on port 443–and they are SSL (encrypted) connections, so that’s good, too.
