Detect if interface is in promiscuous mode with C

问题

I am doing a different tools to check security of linux servers... nothing important and very similar to the tools of chkrootkit. One of the tools I want to do, is like the ifpromisc.c from chkrootkit, that is detect if one of the server interfaces is in promiscuous mode.

I found an answer on stackoverflow: howto check a network devices status in C?

But after check this solution, I noticed is only for old kernels, because new libpcap doesn't set IFF_PROMISC flag when uses PACKET_MR_PROMISC. I have been looking for other solutions without luck. Any idea?

Thanks!
