script to get HWaddr of all nodes on a cluster?
 

Hi,

I need to create a list of all the hostnames and their HWaddr (hardware addresses [also called MAC address]) for all the nodes on my Linux cluster.

I know that all the hostnames can be found in /etc/hosts, but there doesn't seem to be a list of HWaddr numbers.

I guess one can write a script to ssh into all the hostnames found in /etc/hosts and execute the command

/sbin/ifconfig | grep 'HWaddr'

on each node and concatenate this into a single text file. My Linux skills are not good enough to do this though.

Does anyone know if there is a list of HWaddr numbers in a system directory, or alternatively, does someone know how to write a script to generate the HWaddr lists?

Thanks,
Bryan
