So I’m back in work and excited to give GeoChat a try, but I’ve run into a huge roadblock. The TCP/IP port that is required has been blocked. I’ll ask the IT staff to open those ports up, but I guess I could set up a Jabber server inside our firewall for internal use. Richie has posted some more information on his blog you might want to check out. I like how it defaults to the GTalk servers as those are probably the ones that most people will use. I’d give it a shot at home, but all our ArcGIS Desktop licenses have been migrated over to concurrent use and if I use our VPN software it will block port 5222 for “safety” so it really won’t help anyway.
