Where can I find the source code for /bin/ip?
I’ve been using the command /bin/ip:
ip addr add 10.10.10.0 dev eth0
I would like to see the source code of how the ip command works. Is it available?
The ip program is part of the iproute2 software package, and can be downloaded from www.kernel.org. N.b. Unlike the old ipconfig program, which uses ioctls to do its job, the iproute2 utilities use Netlink sockets to communicate with the kernel. It helps understanding how the ip program works if you are familiarised with Netlink sockets.
