Subject: Getting the dynamic IP address of a dialup interface (ppp0)


I need to get the dynamic IP address of the ppp0 interface
(point-to-point) under Linux. I cannot do a reverse DNS
lookup since the associated name is dynamic too (something like
user-bla-bla-IP-.someisp.com), and I would prefer to avoid parsing
`/sbin/ifconfig` since
 a) I don't know how reliable it would be (and it's ugly anyway)
 b) I cannot get sample output to work on since I have no access to the
remote machine (I was planning on somebody installing my script that)

[Context: I'm binding a socket to that interface and sending the IP and
port info w/ UDP to another computer (server) behind a firewall that then
connects to the client. This is all required because of quite draconian
firewalling rules (my machine is behind _THREE_ different firewalls,
ouch!)]

MSDOS didn't get as bad as it is overnight -- it took over ten years
of careful development.
