Query and modify advanced information about interfaces

I need to do following tasks:

  • List the interfaces
  • Set/remove/list IPv6 address
  • Add/remove routing entries

AFAIK I cannot use ioctl I need to use netlink. The problem is that I couldn't find good description how to use it (most netlink tutorials concentrate on how to create connection). strace also didn't prove useful.

Solution

  • I recommend you look at the sources of iproute2. It has all the functionality you describe and uses netlink.
