>Description:
erroneously I executed remotely ifconfig ath0 mac instead of list mac and lost access, I could repeat it locally with any interface name available on the machine as:

ifconfig rl0 mac 

rl0: flags=8943<UP,BROADCAST,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
        options=48<VLAN_MTU,POLLING>
        inet 200.234.196.85 netmask 0xffffff00 broadcast 200.234.196.255

mac is not a hostname nor configured in host file
# nslookup mac
Server:         127.0.0.1
Address:        127.0.0.1#53

** server can't find mac: NXDOMAIN
