view full story

http://ubuntuforums.org – Hello, at the moment I'm trying to set up a simple ssh connection between two computers (running Ubuntu 10.10) on our wireless home network. On both computers I made sure OpenSSH was installed, server & client side: Code: sudo apt-get install openssh-server openssh-server I then disabled both firewalls. Code: sudo ufw disable That's all I have done really, but I still can't connect from one pc to the other. I tested Code: ssh localhost which works So now I try Code: ssh user@hostname for which I get: ssh: Could not resolve hostname XXX: Name or service not known Am I (HowTos)
