. The supported operating systems are Windows, Linux (x86), AIX-5-powerpc64, SunOS-5.10-i386, SunOS-5.10-sparc.

If you use default multicast address (224.252.253.254) and its default multicast port (18162), run the following commands:

On the first machine:

mdump 224.252.253.254 18162

On all other machines:

msend -b1 -m20 -n5 224.252.253.254 18162

If the test is successful, the output displays the following information:
