I have an Ubuntu 7.1 machine, and a Vista Home Basic machine at home. The two are connected to my cable pipe via a Linksys wrt54g router. My mom has an XP machine (not sure if it's home or pro as it's new and I haven't seen it yet). Is there a way to "remote" between these machines for those (fairly often) times when my mom is in need of tech support, or I need to get to one of my home machines from a remote location? I'd prefer something not browser-based, but will take ANY suggestion under consideration.
