trouble with loopback, gnome apps; "SET failed"

[Matt Price]

Hi Ubuntu,

I've installed Ubuntu on a number of rather slow machines (P2-300-ish)
and while on most of them it works fine+ (though gnome runs slllooow),
but on a couple I've run into probleems where administrative apps
(root terminal, network-admin, tc) won't run from the gnome menu.
They'll try to start up (I'll get a "starting app X" icon in the
panel), but then silently disappear.  I can start them from the
command line, though, by firing up a terminal and syping, e.g., sudo
network-admin.  To me this seems like some kind of a problem with X
permissions, but it's hard to diagnose as there are no errors in
syslog and of course no error messages on the screen...

On at least one of these machines I have a problem I thought might be
related,in which I cannot set the loopback interface or the eth0.
Both give the same error -- fas as I remember (no network in this
classroom so I can't reproduce my results perfectly):

'Error for wireless request "set Encode" (882A)
   SET failed on device lo; operation not supported'

I have no idea fwhat this means.  Anyone have any ideas?  

Thanks much for your help, it's appreciated.  

best,

Matt
