Nagios Core 4.02 on FreeBSD 10

Hello Forum
I have installed Nagios Core 4.02 on my FreeBSD 10 server following this guide:
http://www.xfiles.dk/guide-on-how-to-in ... n-freebsd/
Everything seemed to be going ok until I logged into the Nagios website. No matter what I do in the web interface I get the following error:
Code: Select all
Error: Could not read object configuration data!
Yet, when I run:
Code: Select all
nagios -v /usr/local/etc/nagios/nagios.cfg
it says:
Code: Select all
Running pre-flight check on configuration data...

What can I do to fix this error? I did do some research online any a couple places mentioned permissions on the directories maybe?

Is nagios running?
What config file did it load with?

It seems to be working now! I had to add the www user to the nagios group.
I do have one more question though
I need to monitor a few milter services (ClamAV, Spamassasin, and OpenDKIM). These all use UNIX sockets. I have tried to use check_tcp for this but keep getting a permission denied error in Nagios.
Any ideas? I tried adding the nagios user to the Postfix group but this didn't help.

Awesome, yes the apache/http user needs to be in the group
. Can you run the following and show the output?:
Code: Select all
ls -la /path/to/your/plugins/check_tcp

Here we go:
Code: Select all
(~)$ ls -la /usr/local/libexec/nagios/check_tcp
-r-xr-xr-x 1 root wheel 61K Feb 23 08:13 /usr/local/libexec/nagios/check_tcp*
Running this manually:
Code: Select all
(~)$ sudo /usr/local/libexec/nagios/check_tcp -H /var/run/dkim-filter/dkim-filter.sock
Gives me the following output:
Code: Select all
TCP OK - 0.000 second response time on socket /var/run/dkim-filter/dkim-filter.sock|time=0.000020s;;;0.000000;10.000000

It is most likely the permissions on /var/run/dkim-filter/dkim-filter.sock.
You may be able to fix this by editing the init script for dkim-filter or changing the umask settings.
Alternatively, you could use sudo in your command and create a sudoer rule to elevate the permissions of the check.

I seem to be battling with this!
In my /etc/rc.conf I have set:
Code: Select all
miltergreylist_enable="YES"
miltergreylist_runas="postfix:postfix"
I have added my nagios user account to the postfix group (and restarted the nagios and apache services) but this hasn't helped.
What am I missing?

Does if help if you change the permissions on the plugin?
Code: Select all
chown root:root /usr/local/libexec/nagios/check_tcp
chmod 755 /usr/local/libexec/nagios/check_tcp
