[Spread-users] spuser doesn't run with multiple daemons

If it works with 2 but does not work with 3 machines, it indicates to
me that your broadcast address 138.100.12.255 does not work.
You can verify this if you see lots of retransmissions using
spmonitor.

To correct it, you could use a multicast address (e.g. 225.138.100.12)
instead of the 138.100.12.255.

You could also make sure your network is set up correctly on the 3
machines with respect to the broadcast address.

If you are using Spread in a course, it would be nice to know where.

Cheers,

       :) Yair.
