I can telnet and see the data if I am on that machine otherwise I do not have telnet open to the outside world I only allow ssh connections.

Ben,

Quickest way would be to telnet to that machine and port:

telnet machine 8652
If you connect.. your not blocked... you would see XML data in the telnet session. 

HTH,

Pete.

How would I ensure it is not being blocked. I am Running RH9 and have no firewall installed.

Hi Ben:
Port 8652 is the default port for XML data - have you made sure that the 
port is not being blocked?

Cheers,

Bernard

I have read through the archives, and just don't see where in the .conf files I have I am supposed to make modifications to correct this problem. 
------Error Message ------------------
Warning: fsockopen(): unable to connect to 127.0.0.1:8652 in /var/www/html/ganglia/ganglia.php on line 273 

There was an error collecting ganglia data (127.0.0.1:8652): fsockopen
error: Connection refused
------Error Message ------------------
I recieve this error when I try to access the index.php page after setting up the ganglia software packages. I get the proper response from the telnet command. My website is properly opening php files. 

From the archives:

----snip------
in trusted_sources put the IP of the computer (not 127.0.0.1, it doesn"t work for me). in gmetad_sources you MUST add addresse of computer with gmond or gmetad running. 
If 4 computers with gmond :

node1 192.168.200.11 8649
node2 192.168.200.12 8649
node3 192.168.200.13 8649
node4 192.168.200.14 8649

then, killall gmetad,
/usr/sbin/gmetad to restard gmetad.
----- snip---------
I don't see any entries that are trusted_sources. I see trusted_hosts in gmond.conf 

I have the following data source and trusted hosts in my gmetad.conf
data_source "Viper" viper.memphis.edu 127.0.0.1 trusted_hosts viper 127.0.0.1
Is there another file that should exist that I didn't copy over or something else I am missing?
