I’m surprised the daemons ran at all as you gave both machines the same name (Machine1).

Beyond that, you probably have a firewall between the two daemons.

Port 4803 needs to be open for both TCP+UDP.  Port 4804 needs to be open for UDP.  Port 4805 needs to be open for UDP if you want spmonitor to work.

  I am trying to do a test where I have two spread daemons talking to one another using unicast UDP.  I did the following configuration based a email thread on the Spread-users list back in 2009.
Spread_Segment {
Spread_Segment {
Then using the python binding to spread I ran the same script on both Machine1 and Machine2:
import spread
mb  = spread.connect() # connect to localhost daemon
# use poll to listen for activity on mb then use mb.receive() to get the message
On both Machine1 and Machine2 I only see one member in the group, I would expect to see two members for the “command” group and yet I only see the localhost Machine1 or 2.  
Obviously something is wrong with my configuration. The machines are on the same switch next to one another. Multicast is not supported.
