Studying rtnetlink…

February 15, 2013

To implement LLMNR on GNU/Linux, we will have to know the link-local  IPv6 address of each network interface.  We can use the rtnetlink interface for it.  So I must learn how to use it.

I also checked getifaddrs function that returns interface information, but it uses interface names instead of indices and just returns information for all interfaces at once.  It is not very suitable for our needs.
