i have freenas installed, sharing up my files.

trouble is, because it uses dhcp, every time i make a change and boot up it assigns a new ip address and i have to get the monitor and keyboard out, plug it in to the freenas box and find out what ip address its using this time.

is there a command i can use that will show me what ip address it has been connected on without having to plug the monitor in all the time?

zenmap is a graphical front end for nmap, available from the repositories. You basically sepcify a host or block for it to scan then set it loose.

For instance if your address range is 192.168.1.whatever and your netmask is, you would type 192.168.1.* to see all the hosts whose IP starts with 192.168.1
