Hi
I've got the mac-address of desktop. But I don't know it's IP, are
there any tools that I can use to find this IP.
Presuming you're on the same LAN, and the desktop is not running Windows
(which does not respond to the broadcast address):
Linux can be configured to not repond to broadcast pings, and windows
can be configured to respond to the,;-\
ping -b 192.168.0.255 (substitute with your broadcast address)
/sbin/arp -a | grep 00:10:00:FF:FF:FF (substitute with the MAC
address of the desktop)
Failing that, you can watch network traffic and hope the desktop machine
generates some traffic:
tcpdump -v ether host 00:10:00:FF:FF:FF
If you're using DHCP, then check the DHCP server's logs.
You can also use a shell script (or a small series of commands) to ping
all likely addresses (google should find some sample bash scripts for
you) and see what arp says.
nmap also has the ability to ping a range of IP addresses, and scanning
your local LAN for http servers would be quick (but less educational
than the scripting approach) and create the needed ARP entries.
