Glad you figured it out.  I realized after the fact I'd written "etho"
instead of "eth0".  Then figured if you couldn't work that out, you
wouldn't have got this far :-)

I'm just setting up the wireless network here, but I really can't see why
whereami wouldn't work just as well on wireless.  Maybe by tomorrow I'll
know.

No idea.  I've used "intuitively" (which is fairly good, but I just have so
much trouble typing "intuitively" any time I want to try to change
something) and "whereami".  Whereami has the advantage of having one of the
two most responsive maintainers I've ever seen, so if you post a question
on debian-laptop you'll almost always get a quick solution.
