The change in rwhod from -12 to -13 causes it to log to the syslog every 3
minutes.

I diffed -12 and -13 and noticed that it calls configure(sk) in the main loop
and that it "forgets previous neighbors; interfaces may have changed".
I'm using rwhod with -i eth0 to limit to my internal network.

I also noticed "2013-09-22 15:13:23 ani rwhod[28401]: specified interface eth0
more than once" was listed.  Downgrading to -12 fixes the problem for me.

Maybe make this a switch?
