Hi,

what happened to network devices like /dev/eth0?

cat:~# dhcp_probe -f /dev/eth0
note:   starting, version 1.3.0
error:  dhcp_probe: bad interface '/dev/eth0': SIOCGIFADDR: /dev/eth0: No such device
note:   exiting
cat:~# find / -name eth0

This is utterly retarded :( Which one is "/dev/eth0"? What is one
supposed to use when typing commands or in scripts to specify
"/dev/eth0"?
