[conspire] running ifconfig - getting errors and collisions

[Daniel Gimpelevich]

First thing to look at would be the lights on the DSL modem. If there's
nothing unusual there, try to ping a known numeric IP address. The third
test is to ping a named host, like below. Since you're on DHCP, one thing
you can try when you have a problem is to bring down eth0 and then bring
it up again.
