Finding all users on a LAN and their IP

On a local network, how can I generate a list that includes all usernames with their current ip?

I get this list in Apple Remote Desktop but it would be much more handy to be able to get this kind of a list in Terminal.

Using Terminal on a Mac.

Thanks for this awesome forum!

On all *NIX there is last coomand which can help you out if people are logging onto a common server. On Windows there are API which can query to NTLM database and get enumaration. No knowledge about Apple Mac.

Thanks very much anyway. I am using Apple Tiger server. I will look further on apple.com.
