Subject: [gentoo-user] Packet sniffing broken recently?
Date: Wed, 28 Dec 2011 17:01:59 -0800	[thread overview]
Message-ID: <jdge68$12q$1@dough.gmane.org> (raw)

Sometime in the last month or so (when I wasn't looking) my
~x86 and ~amd64 machines quit working when I try to run
wireshark or tcpdump, etc, but I don't know exactly when
or why.  (My amd64 machine still sniffs packets normally.)

I get this same error from any packet sniffing app:

Can't open netlink socket 93:Protocol not supported

Strace shows that this is the failing system call:

socket(PF_NETLINK, SOCK_RAW, 12) = -1 EPROTONOSUPPORT (Protocol not supported)

That makes me think of some missing kernel config that may
have been added or modified in recent kernels, so I tried
gentoo-sources-3.0.6 (same as my working amd64 machine) with
no joy.  Same error message.

Have I missed some important gentoo bulletin about networking
recently?  Anyone have working packet sniffing on ~arch?
