Network Manager cannot create a working connection. To connect, the user must run dhclient with root privileges. Below is the current content of /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp address 192.168.0.254 netmask 255.255.255.0 Could the installation of Linux Terminal Server Project have caused this? During the installation, I opted to include LTSP and there was a list with the default option of eth0, the only network device I had then. I presume that as a terminal server it would need a static address, but I'm not an expert in that - yet. If that is the problem, how do I correct it? Do I add another network card and make LTSP use that so the other can be set to use DHCP and start at boot? Or do I remove LTSP and hope that will solve the problem? Do I start yet another wipe and install, this time without LTSP?

Usually you'll have to specify the MAC address for the network card in the computer, but some routers will do it via 'computer name'. I'm not too familiar with LTSP, but that's the first thing that came to mind when reading your problem. Cheers, Phil
