Aaahh...  Physical...  try doing a ping, or some such, & run ifconfig
- -a again.  You should see a change in the number of packets each way.
 Also, check those status lights on the hub & so on.

You might also try an ethernet sniffer on a different machine (e.g.
etheral)

Subject: Re: Interface status


on my computer it does not work, i disconnected the wire from
the ethernet port and the ifconfig is the same, i think it
tells if the interface is up in the kernel, not if the inteface
has carrier from switch/hub. This is from ifconfig man page:

        up     This flag causes the interface to be activated.  It
               is implicitly specified if an address  is  assigned
               to the interface.
