That is very nice to know, thanks Greg.
I wonder if this applies to other linux distros as well...
Or can be changed in the ip*.c & .h files and fixed with a recompile?
Anyone?
Thanks,
Joe

Subject: Interesting issue while testing multicast. TTL value from linux
box.
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.
