I have attached in text form the two files. I compiled from source
because all of my clients at the moment are Fedora Core2, and I am
intending to bring up a set of Solaris 8 computers later. I also didn't
see a complete set of RPMs on the site to download for all the pieces
for RH9.

Hi Ben:
It might help to post your gmond.conf and gmetad.conf files.
BTW, any particular reason you're compiling from source? The provided
RPMs install fine under RH9 systems.
Cheers,

Subject: Re: [Ganglia-general] Re: Web Frontend Help - fsockopen error
I have tried adding the port to /etc/services under the name
of gmetad.
This doesn't seem to get me anywhere. I tried to change the
interactive_port in the gmetad.conf file, but that parameter
is unknown or is parsed incorrectly based on the error
message Starting GANGLIA gmetad: gmetad config file error: Unknown
Config-Option: 'interactive_port' [FAILED]
Any other thoughts as to how to open the port? I assume that
gmetad is
supposed to do this itself but is failing for some reason on
my box. I
am running RH9 and Apache 1.3.31, php-4.3.8, and ganglia monitor core
2.5.6 built from source.
Thanks in advance,
Ben Simmons

Ben,
Having telnet open to the outside world does not matter.... you are
using telnet to connect to a specific port.. not to telnet's port.
Can you telnet to that machine with the port 8652 from any machine
other than itself?
telnet to port 8652 from machine2 to machine1:
machine2> telnet machine1 8652
If that does not work.. than you need to open up port 8652 on the
machines to allow access from your other machines.

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,

Port 8652 is the default port for XML data - have you made sure

error
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?
