All machines in the LAN use DHCP. Do I still need to put the IP/names in /etc/hosts?
Are there any other options?

The only way to do that is to put the names and ip addresses of the machines in your lan in your /etc/hosts file. There is no other way to do it.

I tried "nslookup 192.168.0.1" but it didn't work. It works fine for public IP addresse but it doesn't work for the private
ones. (192.168.0.1)
Is there any other command/tool I can use to resolve IP addresses into names for PCs in my LAN????

I think the Windows version uses NETBIOS to resolve names that don't have a DNS entry.
Use nslookup. That will return the name as registered with a DNS server. It won't use NETBIOS so private IP address probably won't be resolved unless its in your /etc/hosts files.

Hi gurus,
Windows' command "ping -a 192.168.0.1" will resolve the IP address 192.168.0.1 into to a name if possible. What is the linux analogue of this command? Linux ping command doesn't seem to be able to do that... Any ideas? ============================ C:\>ping -a 192.168.0.1
