On my Linux box (Mandrake 6) which uses pppd to dial in:
[root@fred /root]# /sbin/ifconfig --version
net-tools 1.52
ifconfig 1.39 (1999-03-18)
(I believe the ifconfig output is the same across any semi-current
version, but just in case, that's what I'm using)
This will work:
echo `/sbin/ifconfig ppp0 | grep 'inet addr:' | cut -f 2 -d : | cut -f 1 -d ' '`
Or, if you're a little less masochistic (shell scripting-wise),
the /etc/ppp/ip-up script has the IP address given to it as $4, so you
could just stick a:
echo $4 > /root/current_ip
in /etc/ppp/ip-up and then just do a `cat /root/current_ip` to get at it.
(the parameters passed to ip_up and ip_down are documented in pppd's man
page.
Hope this helps,
