xubuntu on vmware server - no network interface?

I have a pre-built vmware virtual machine. I did not build this machine myself (stuff that's a major PITA to get right is pre-installed).

The problem is that there's no network connection out.
When I run ifconfig, I get details for a local loopback, but no eth-anything.
ifconfig /etc/network/interfaces
gets me
/etc/network/in: error fetching interface information: Device not found

When I looked in /etc/network/interfaces there was no mention of eth0 (or any other eth)
so I added
auto eth0
iface eth0 inet dhcp

and rebooted.
This didn't seem to change anything.

I'm trying to figure out interfaces (man interfaces) but I'm not sure I'm even looking in the right dark corner.

Anyone have some suggestions as to what to try (or, better yet, pointers to some docs and some hints). I don't find networking particularly mysterious but am not (yet) clear on which pieces are where in linux.

Im not sure about vmware but in dmesg you can find out what interface you have. If vmware configuration is correct , it share phisical one. After you just use ifconfig to asign ip to it.

I think my problem is, indeed, between drivers (which would normally connect to hardware but in this case would connect to vmware's virtual ethernet card, and whatever level defines eth0).
Do I just define that in interfaces.conf or is there a set of definitions "one level down"?
All the ubuntu/debian VMs I've looked at just have
auto eth0
in interfaces.conf - so I'm guessing there's another conf somewhere that defines what driver maps to eth0.

A pointer to a good "nuts and bolts of how linux networking works" would help (online or dead-trees).

Thanks again!
