How can I check if my ethernet port is working?

How can I check if my ethernet port is working? I had a cable burnout and had to replace the network cable linking my minimac to the router, and now it doesn't work. The same new cable will link other devices to the router, but not the minimac, so the problem must be here. How do I check the hardware and the software connections?

TIA

minimac, Mac OS X (10.5.5), I also use ubuntu linux

If you have another Mac you can connect them with a simple ethernet cable.

Connecting two computers using Ethernet

If you cannot make that simple connection then the ethernet may be burned out as well.

And if I don't have another mac? Isn't there some way to run a diagnostic tool of some description?

One quick check is to start "network utility" located the the Utilities subdirectory of you application directory. Hit the info tab at the top and select your Ethernet in the drop down box. See if you have a connection.
