setting net.ipv4.neigh.eth0.gc_stale_time = 5 //a ridiculously low value and watching the interface with tcpdump -i eth0 arp does not force arp requests every 5 seconds as you might expect. reading through /net/core/neighbour.c doesn't really give me any ideas as to what's going on. net/ipv4/arp.c has the functions for creating and sending arp packets, but I'm missing the governing logic. _______________________________________________ EUGLUG mailing list [email protected] http://www.euglug.org/mailman/listinfo/euglug
