Re: no network connection

[Ed Sutter <esutter@alcatel-lucent.com>]

My goal is to have the debian-based system start up with Ethernet
enabled immediately (I would have thought that would be the standard
way it would boot up).  I don't want to have to log into my console
and click something to start up Ethernet.  My typical usage of
this system is to ssh into it from another machine, that won't
necessarily be local to my debian machine's console.  This all works
fine, except that I have to log into the console the first time after
bootup to enable ethernet through that icon I mentioned earlier.

I assumed that the ifup/ifdown stuff discussed in the "man interfaces"
was referring to some call to ifup that was being done during
system startup somewhere; hence, the reason for my reboot.

See what I mean?
