comment Transform an UDP unicast packet into broadcast?
@Hauke Laging: good remak. I think it is broadcasted on all interfaces when using 255.255.255.255 (not tested). So 192.168.0.255 may be a better option in some cases.

@lgeorget: "echo 'dummy' | nc -u -q 0 127.0.0.1 1234" works perfectly with -UDP-LISTEN. I can run it several times. But I have problems with -UDP-RECV and -UDP-RECVFROM: the packets are broadcasted at maximum link rate until socat is killed. Do you see the same problem with tcpdump ?

No problem here. You used the "fork" option ? I see in the man UDP-RECV merge packets. I have no idea about what it means. UDP-RECVFROM doesn't exhibit this behviour, but it may be an error in the man.

@lgeorget: iptables is not related to so sockets.
