#1266 — Finding the IPs of up interfaces in /proc

Hello.

I'd like to know if there is an interface in /proc that can tell me if
an interface is up, and what IP it has.

I'm writing an applet that uses tun0 for a VPN, and I'd like to put up
a tooltip showing the IP given to tun0 after the VPN connected, or '-'
if it is not connected yet.

I have look in /proc/net/*, but I haven't found anything
relevant. Only /proc/net/arp shows an IP, and it is my router's.

Thanks!

Try  /sys/class/net  instead.

Yes, I looked in there too, but nothing about IP addresses... I can
get the MAC address, but that's not what I want.

Thanks for the help though.
