Ofcourse us been system admins its easy, we just sometimes we have those
metal blocks :)

        Works sunos and solaris.

1. as 'root', `ifconfig -a` will give you the ethernet address
        of all Ethernet cards:

        examples:

        o ifconfig -a
        o ifconfig -a | grep thernet

        Works solaris (not too sure about the results in sunos).

2. as anybody or root use `arp`

        examples:

        o arp -a | grep `hostname`
        o arp `hostname`
        o host2% ping host1
                host1 is alive
                host2% arp host1
                host1 (aaa.bbb.ccc.ddd) at 8:0:20:xx:xx:xx
