I'm having some problems connection to my home computer (Win XP) using my Ubuntu 8.04 laptop.
I can make the connection when I'm at home where I don't have to deal with my 'outside' ip-address but only the router given ones. I installed Cygwin on the Windows machine so please ask me anything about that if you need to know. I'm using Putty on the Linux machine, and like I said it works perfectly when at home. But when I try to use it anywhere else using the hostname
I get a 'Unable to open connection to computername@outside-ip-address: Name or service not known'
Please note that I am a beginner so if you could post questions like 'Do you have xxxx setup ? You can see it by doing yyyy' that would be great.
