I don't suppose the network-manager bugs have been fixed yet, have they?
On my machine after upgrading to 8.10 I could no longer use a static IP!
THAT is a PITA!

I don't know if it's that simple (well, yes, you can do it with a /hosts
file not arguing that) but in today's networking a lot of printers do
advertise themselves so they're discoverable. I just opened "networks"
on this Ubuntu machine and there are four networked laser printers
showing, and Macs with Rendezvous love discovering printers for breakfast.
I really think it won't be much longer before Rendezvous and
autodiscovery (same service, isn't it?) and IPv6 will make networking
three times more magical for users and four times more frustrating to

Or open the management page to your DHCP server and it'll tell you
what's connected :-)

That's how mine was set up...well, until Network Manager crapped the
bed. Lost my webcams, lost my network, miffed more than a little I am,
just not *quite* enough to revert to 8.04.

I think he was right and wrong at the time in what he said can and can't
be done with it, but I don't feel like digging through archives at the
moment just to prove a point. I'm not in the mood to drop trou just to
prove my geekness.
