Problem with Monit talking to M/Monit

[David Parks]

I just installed Centos 6.4 minimal on a server and, for some reason, I can't 
get the monit client to talk to our M/Monit server.  On the new Centos box, 
I've stopped the firewall just to rule that out and I can "talk" to the M/Monit 
server on the correct port, but M/Monit doesn't see the new server.  I assume 
there is probably a necessary package that isn't installed on the Centos box, 
but I'm not sure. 

Any ideas on where to look before I install some network sniffing packages on 
the Centos and M/Monit server itself?

Thanks,
David
