IP conflicts while updating ARP table on a router

[Gris]

Hi!

 

I have one strange problem with Leopard's networking. All IP are linked to MAC addresses on my ISP's router (gateway). Each time when ARP table is updated on a router (occurs each 5 minutes), I receive IP address conflict with my own IP and MAC. The network interface not goes "down", but all network activities dramaticlly slows down for few seconds. I assume, that it occurs because Mac OS reacts to the broadcast packets sent by a router during the updating of tables though should not do it. In general, OS must not react to ARP packets with the same IP and MAC as it's own. All other operating systems (Windows 95 - Vista, GNU/Linux, *BSD, Solaris, Mac OS X 10.4) works just fine.

 

Whether somebody have a similar problem or may be found a solution?

 

Thanks.

This problem is solved.

 

To avoid getting conflicts, a following line must be added into /etc/sysctl.conf. (If no such file exists in /etc, then it must be created):

 

net.link.ether.inet.send_conflicting_probes=0

 

Also this can be set from console for current session only using following command (you must be root):

sysctl -w net.link.ether.inet.send_conflicting_probes=0
