Check following

arp -a and look for the pc ip address. Along with that you will get mac address.

man arp for details.

Hector,

If the client is in the same IP subnet as the server, then you can refer the arp cache.

# arp -a | grep

But not sure if you can find out the MAC address of the client from a different subnet.

Can issue the 'lanscan' command. The command is in /usr/sbin/lanscan

Rick/Doug - I believe Hector is looking for the mac address of the CLIENTS, not the UX Server itself.

OK, if looking for the client MAC, go with Sundar.

oops. If the client is on the local segment, then arp -a is the way. sorry.

Hi,

you can use the nettl command to monitor your network. this is like a sniffer. the only problem is that the log could be quite big and difficult to read.

Here is a link on how to enable and disable nettl for a short duration to check things out.
