Thanks for the replies. I tried the method sugested of the ssh command. When I do that, I get the following error on the command line

Received disconnect from XX.XXX.XXX.XX:
Switch: SSH protocol error - packet type not expected.

I have not had chance to try the shell method with Net::SSH::Perl yet but I shall get onto that and post back with how I go.
Thanks for the help so far
