Onw whay to do this would be

who -R

This will give you the host name the user is logged on from and then do

arp hostname

Hope this helps.

I believe HP-UX ARP implementation will only cache the MAC address if the interested machines are in the same subnet as the server.

ARP cache is a kernel data structure and can be displayed using arp -a command.

Hi!
Not for logged users,but the mashines cards,
connected to your server:

#arp -a

After that you can use who -R to
see user-mashine relationships
and to find needed information.

Hi,

HP-UX does not store the MAC information for the users. The best you have is only arp cache and if the remote system is not on your network, what you see is only the MAC address of the router interface.

The login information is stored under /etc/utmp* and /var/adm/wtmp* files. You can retrieve it by last, who and finger commands.

If the user is no longer logged on, you can use "last -R" instead of "who -R" to get the host names. If you get too many lines output but you can limit it with the "-number" option to the "last" command.
