While testing a multicast setup I ran into an issue where my test linux box
couldn't work as a multicast source.

The problem ended up being the TTL on the multicast ping packets.
Apparently the default behavior on my distro, Centos, is to set the TTL to 1
on multicast pings.

I added the -t flag and magically everything worked.

ping 233.1.1.1 -t 101

Hope this helps someone.
