How can I use a NETLINK socket to data from kernel space in PYTHON?

Question

There are netlink libraries. You might need to be more specific in your question. You ought to go through your previous questions and accept some answers too. — MattH, Jan 13 '11 at 11:36

Do you maybe know an answer to the question over [here](https://stackoverflow.com/questions/35876323/netlink-multicast-in-kernels-above-4)? – user1252280 Mar 10 '16 at 18:38

Use sock.bind((0,-1)). The second argument (-1) is a bitmask of groups to monitor. Setting to -1 sets all bits in the mask. – David Poole Feb 23 '17 at 16:08

I believe that the socket Python module has had support for AF_NETLINK sockets since Python 2.5 or so, although I have never used it. There are a few projects out there that use it and can serve as an example:

Searching Google for /usr/bin/python af_netlink comes up with a few more hits, although I will admit that most are not really useful.
