I run my openmpi-based application in a multi-node cluster. There is also a
sniffer computer (installed with wireshark) attached to a listener port on
the switch to sniff any packets.

However I would like to know the protocol (UDP or TCP) as well as the ports
used by openmpi for interprocess communication so that wireshark can only
capture these packets.

Thanks!
