Hi. I'm at bristol uni and at home in rbistol (with daemon internet) I can ssh fine into Bristol's server.

When i tried it in london (using talktlak broadband) it kept saying connection closed. I e-mailed a tutor thinking the server's had been shut down, and he said "if the connection is closed, then that is because your ISP does not
prvoide a reverse DNS mapping". This guy is really clever but before I go on and move from talktlak to demon i just wnat to check that that is the only problem that could be cuasing this.

For example i'm yusing a differnet wireless route (belkin vs netgear) and am wondering if that could be anythin to do with ti.

thanks for any help.
