i thought recvfrom() fixed this issue? Forgive me if I'm wrong here - it's been far too long since I've done any socket related stuff. > => BIND polls from time to time interfaces to bind() to new addresses > (again, there is no standard/portable way to be notified. BTW we (ISC) > know this is a point which can be improved so if you know a generic > simple solution...) server.c:load_configuration() has: interface_interval = cfg_obj_asuint32(obj) * 60; which means that the granularity for interface rescanning is per-minute. I'm not suggesting that per-second rescan would be a good idea, but per-minute is too long for workable failover with vrrp. Nick
