MAC address

[muzica]

Hi,

I have a IP Address of a remote server on my network.
How can i find the MAC address.

[falko]

Log in to the server and run

ifconfig

That command will show you the MAC address (I think it calls it HWADDR or something like that).

Thanks, but I don’t want to log on to 68 servers. Is there away to innovatory them from a command line?

[falko]

I'm not sure if the nmblookup can be of help. Run

man nmblookup

Maybe it can detect MAC addresses.

Hi Muzica,

I use nmap for that type of task.

the following command will scan your entire subnet and provide just the info you need;

nmap -sP 192.168.0.0/24

Replace the 192.x.x.x with whatever you subnet is, also if you're not using one of the standard subnet masks you'll need to calculate and apply a different subnet # at the end (24).

Since you have a bunch of machines I'd suggest routing the info to a file like so;

nmap -sP 192.168.0.0/24 > MyMacs.txt

Then you can copy that text file to whatever machine your doing work on. I use the heck out of this command when setting up Static DHCP servers.

Cheers!
Ken
