[ale] Get host's IP address as an unprivileged user?

[James Sumners]

Hmm, the script is for some RHEL4 boxes. Doing `up2date
--show-available | grep ip` doesn't show the iproute2 package as even
being available (and I grep for 'ip' just to even get results).

Just to play around with the ip tool (as I had forgotten about it), I
checked on my Arch and Debian boxes. Looks like iproute2 is not
installed by default on Arch and it is installed by default on Debian.
But on Debian, `ip ls` is an invalid command. I believe `ip addr show
eth0` gives the results you're suggesting. The information listed
would require some more parsing than my original one :-/

I find it odd that it takes jumping through so many hoops just to get
the local (primary) IP address for scripting.
