Hi Hangbin, can you please rerun omping with -vvv parameter? This will give you a lot of debug messages and this should help us to identify problem.
But if not bug, it really looks like you have multiple NICs with same IP (ether 10.16.40.142 or 10.16.42.40).
Jan,
With "-vvv" find the reason . I add a br0 on eth0 , so there is a fe80::62eb:69ff:feba:c932 on both eth0 and br0 . delete the fe80 addr on eth0 and omping going on well .
But I can't got any response msg from other remote hosts except from myself. Doesn't understand multicast clearly , can you tell me why ? Thanks.
/* without bridge , just an eth0 */
