Why not post in that thread where people are actively working on the installs. Getting MRTG running requires reading the docs and compiling/configuring it correctly unless you can find a package that is available like the one in the thread.

I am running centos 4 and I was able to install it with these exact instructions:

1: rpm -e mrtg
2: rpm http://www.interxstream.com/mrtg-2.9.17-1cpanel.i386.rpm -Uvh
3: cd /usr/lib
4: mv libpng.so.2 libpng.so.2.OLD
5: ln -s libpng.so.3 libpng.so.2
6: pico /etc/sysconfig/i18n
7: change LANG to LANG="en_US"
8: Start and stop MTRG several times ignoring errors ... service mrtg start/stop/restart
9: chkconfig --add mrtg
10. Add this line to httpd.conf at ver top: Alias /mrtg/ /usr/local/apache/htdocs/mrtg/
11. Restart httpd - httpd stop -> httpd startssl
11: Now check http://YourMainIP/mrtg/

Don't forget the trailing "/" on step 11....

Just run the following command and it will install mrtg automatically for you.

yum install mrtg

For some reason it seems that UPCP breaks MRTG every night. I installed this yesterday, everything was working until this morning, where I started getting a ton of errors. Which I didnt copy.

Then I tried to restart MRTG by doing a service mrtg restart, and it was unrecognized. I was able to start it by doing a /usr/bin/mrtg /etc/mrtg/mrtg.cfg start and then it still wasnt working, so what happened?

I do a chkconfig --list |grep mrtg and its not there anymore.

I try to do a chkconfig --add mrtg and I get an error.

chkconfig --add mrtg
error reading information on service mrtg: No such file or directory

With witch install did you do it:

[recommended]yum install mrtg

or

1: rpm -e mrtg
2: rpm http://www.interxstream.com/mrtg-2.9...panel.i386.rpm -Uvh
3: cd /usr/lib
4: mv libpng.so.2 libpng.so.2.OLD
5: ln -s libpng.so.3 libpng.so.2
6: pico /etc/sysconfig/i18n
7: change LANG to LANG="en_US"
8: Start and stop MTRG several times ignoring errors ... service mrtg start/stop/restart
9: chkconfig --add mrtg
10. Add this line to httpd.conf at ver top: Alias /mrtg/ /usr/local/apache/htdocs/mrtg/
11. Restart httpd - httpd stop -> httpd startssl
11: Now check http://YourMainIP/mrtg/

If it is the last you can fix it by the following way:
pico /etc/yum.conf
find: exclude=httpd* mysql* php* perl* spamassassin* mod_ssl* kernel* courier* apache* exim*

add: libpng* png*


Good luck!

It was the last one, I will try this out. Thanks.

Well, I made the changes and MRTG has been destroyed again.

Here are a few things that start appearing in the console.

This is the script that mrtg.cfg uses.

Maybe just un install it and use, because the mrtg is very old:

yum install mrtg

I know about the mrtg.cfg file, the problem is upcp breaks it. Anyhow, I found something that may fix it.

This will tell upcp not to update mrtg.
