Well, I know this is quite frequently asked topic but I am compelled to ask this because after 3 days of trying,trrrying and trrryyying I am still unable to lauch internet from linux.Basically, I have a dual boot system with XP home and recently installed Fedora Core 4. Sify client works fine on XP but when I try to launch it on FC4, it says"Invalid Session. Relaunch your dialer.". I don't know what's the problem is. I tried pinging to the gateway and it's working fine.I also tried installing windows client through wine but it say something like "Lan cable not connected". But then how can I ping their gateway???Can somebody heeeelllpppp??? I badly need it.Manish
