[Nut-upsuser] Configuring APC Smart-UPS 2200 on two computers

I have a dual controller box similar to this -


On one controller I have Nut configured and working as a server. On the
other side I'm trying to configure Nut as a slave to query the other side
and for some reason it's not working. I'm getting this error:
    "Error: Connection failure: Connection refused"

I'm running with the following set up
OS - CentOS 6.4
Nut - 2.6.5-2el6.x86_64
Nut client - nut-client-2.6.5-2.el6.x86_64
UPS - APC Smart-ups 2200

I installed both nut packages via RPM's taken from the links above. I have
a pastebin link below with all the configurations. I only added in the
lines that weren't commented out. Also if there is only a config file
listed for but not one listed for it is because has the exact config file. I also do not have iptables or
selinux running. I also have this same exact set up running on Fedora 11
and nut package 2-4.1-12.fc11.x86_64 so I'm not sure what the difference
is. is the master and is the controller directly connected to the
UPS is the slave and is the controller that I want to poll for information.


I feel like it's a stupid configuration issue that I've missed so hopefully
somebody can point it out for me. Thanks!
