Howdy, I have just finished updating a new tool in src/tools/tools/mctest which is a multicast test program. The mctest program works by sending packets from a source to a sink over using a multicast address and then the sink reflects the packets it receives back to the source. The source records the transmission and reception time of each packet and reports the round trip time, which the sink prints out the time between packets, in microseconds. The program is best used to debug ethernet drivers as well as our multicast and UDP code. For more information please read the manual page. Sorry, IPv6 is not supported as yet, only IPv4. Best, George
