Hi,
I am facing a peculiar problem. socket.gethostbyaddr is not working
fine on my MAC for ip addresses on the LAN. The LAN happens to consist
of linux and windows machines and this is the only one MAC on the
LAN.
Please see the example below. I am getting error: socket.herror: (1,
'Unknown host')
apples-computer:~ apple$ ping 192.168.4.123
