I've broken my window manager on my Debian 6 machine, and so I am stuck to recovery mode for now. That is, I got a plain root shell. Now here's my problem: how can I get a internet connection, so I can pull new sources and compile my window manager?
ifconfig eth0 up
/etc/init.d/network-manager restart
does not work. eth0 is up, but I cannot access the internet. What's wrong?
