I run a debian system (off of a live cd) and after I upgaded an install my cable modem no longer worked (I am writing this off of the live-cd). Now often, after I break my system, I would merely reload the original system but this time I figured that I would keep the upgraded system for the fixes of any vulnerabilities.
The last time something similar happened (really the same thinhg) I found a webpage tht said that to get a cable modem to work you needed to enter some commands. Like a dunce I did not write the string down and as such I need them again. Does anybody here know of such a webpage?

or

Now it seems to me as if dhcp isn't running so I entered the command /sbin/dhclient but a got a 'no such command' response.

I am now tired and must go to bed.
Good night!
