Finding machines connected

[lightman47]

Back in my Windoze days I used a program on my network that would find and report machines on my network/subnet. I believe it did it using a PING type deal on all 253 possible addresses.

Is there such a program in Linux/CentOS? I ask because I have a machine that, when I bring it to another network (my brothers), it will acquire a DHCP address that I'll not know and it's HOSTNAME will be unknown to that network. To add just one more flavor - it will be headless and I will wish to ssh into it.

Thank you.

Wow - didn't know nmap would do that (don't use it much/know much about it). Thank you!

Also, fping will do something similar.
