[gentoo-user] ifconfig and ppp0 address
For years I have been using ifconfig and some simple shell magic to extract the ip address from the adsl ppp session when it changes. The latest update has changed the output format of ifconfig breaking things so if ifconfig cant be relied on, what's normally used to extract an interfaces IP address? I can easily rewrite the shell magic, but its worth asking if there is some command better suited. BillK

BillK ip tends to be a little more consistent and a little more script-friendly than ifconfig: ip -o addr show -o prints output on one line, making your subsequent grep, sed and awking easier -- Alan McKinnon alan.mckin...@gmail.com

If you're a Python fan there is a nice tool to replace 'awk' and
similar tools:
svn checkout http://pyp.googlecode.com/svn/trunk/ pyp
I've patched this to include a 'balanced' (parenthesis, brackets,..)
With the original version I use
ifconfig wlan0 | /usr/local/bin/pyp
pp.after('wlan0',2)|p[1]|p.re(r'(?=inet )\d+\.\d+\.\d+\.\d+')
If someone is interested in my patch I'm happy to share it,
Helmut.

I can easily rewrite the shell magic, but its worth asking if there is some command better suited. I wrote a command in C++ that interrogates the TCP/IP stack directly to obtain the IP address of any given interface. I wrote it some years ago, so it's only IPv4 at the moment; it will take a day or two to add IPv6 support. I can send you the source code if you want.
