Hi all,

I'm curious how one goes about getting the current IP addresses held by a
machine.  I saw some rather convoluted code in qmail that shows how to do i=
t but
it seems like a rather difficult (and future bug ridden if the interface
changes) piece of code and was thinking that a /proc/net interface would be=
 the
easiest solution, at least on the end user side.

My thinking goes along the lines of adding a file in /proc/net called inter=
faces
(or something more appropriate) which gives the following type of listing:

eth0 12.35.23.58
eth0:0 192.168.0.1
lo 127.0.0.1
ppp0 45.3.3.89

etc

for each of the registered interfaces on the machine.  Nice, simple and
shouldn't be too hard to implement, correct? Is this type of information=20
already present through some other mechanism that I haven't found yet?

Thanks in advance.
