MulticastStats expects the last argument to be a valid broadcast 
address or multicast address.  That is neither.

Try:
225.168.100.1:4445,1 on both machines (a valid multicast address)

Or, if you can't/don't want to use multicast use the valid broadcast 
address for these machines.  It is likely:
192.168.100.255:4445

Sounds like you have differing version of glibc on that machines -- 
Thank Linux for that, ugh.  Compile things on the older box if you want 
to be able to move them around as binaries -- you'll likely have better 
luck.
