Is it possible to manually activate an eth0 connection?

[Brian]

A couple of editors are installed by default, including 'pico', 'ed', and
'vi'.
Both have somewhat idiosyncratic commands. I suggest looking at the man
pages first otherwise you will get frustrated with them for sure.

I also suggest getting a handle on the things folks generally do to
troubleshoot their networks. There are a lot of guides online for network
troubleshooting with ubuntu
