Juszak, sadly it's not possible. I can imagine to make it possible one day in a way, that one omping is running as a server and accepting requests to reply to block of mcast addresses and then have omping client which does let's say 2-3 pings in cycle and requests block of mcast addresses (something like for i in `seq 1 254`;do omping -O client -m 225.25.1.$i -c 3;done), but it's not possible yet.

Juszak, Chris (US SSA) napsal(a):
Is there a way to have omping simultaneously check a block of multicast addresses between several hosts? I'm hoping to check a block; something like 225.25.1.1-254.
