/sbin/ifconfig is now obselete, has been since the introduction of
the 2.2.x kernels.
There are many ways to do this sort of thing, and I would suggest
doing it like this:
ip=$(/sbin/ip -o a s dev eth0 | grep inet | awk '{print $4}' | cut -d/ -f1)
hostname=$(host $ip | sed -e 's,^.* pointer \(.*\)\.$,\1,')
The new networking configuration tool is /sbin/ip -- and it is a
VERY powerful utility! With it you have almost total control over
all aspects of your network configuration, including arp, routing,
addresses, device states, routing **RULES** (very powerful!!),
ip tunnels and so on. "/sbin/ip help" and you'll start to get an
idea what is capable of. "/sbin/ip address help" and "/sbin/ip
route help" (or "ip r h") will be even more revealing.
ifconfig can only do a fraction of what /sbin/ip allows you to do.
Go get the advanced routing howto and find out what you are missing
out on.
