Nagios was set up for the server recently and the following warning shows up regularly :

===================================================
Server Last Stats WARNING 03-10-2010 19:25:46 0d 7h 17m 53s 3/3
WARNING on /var/cpanel/lastrun/ – Last updated 161545 seconds ago.
===================================================

Solution :

First, try running the script /scripts/runstatsonce
If that doesn’t work then go to /var/cpanel/lastrun/ & touch the files in the folder.

#cd /var/cpanel/lastrun/
#touch *

If this does not resolve the issue either then kill cpanellogd & restart it.

#pkill cpanellogd
#/usr/local/cpanel/cpanellogd

This should fix the issue!

It seems that by default, it is set to reject mails with a spam score of more than 20 at SMTP time. How to change the value of spam score for rejecting the mails at SMTP time ?

Solution :

You can do that by doing the following :

1. Go to WHM >> Main >> Service Configuration >> Exim Configuration Editor
2. Look for the section ‘ACL Options’ .
3. The first parameter under that deals with the spam score setting at SMTP time. De-select the check box corresponding to that.
4. When you de-select the check box, it will give you the other available options. Check the box corresponding to the desired value.
5. Click on ‘Save’ at the bottom to save the settings.

Issue :

The server hostname was changed. Ever since that, secure access such as http://servername.new:2087 redirects to https://servername.old:2087

Fix :

This happens when the SSL certificate has not been reset for the services.
Go to WHM >> Manage Service SSL Certificates.
Re-issue all the service certificates.

This should resolve the issue!

How to enable SuPHP ?

Solution :

Login to WHM.

Go to “Service Configuration >> Apache Configuration >> Configure PHP and Suexec” and check if SuPHP is available in the drop down menu. If it is available then select it and save the configuration after a dry run.
SuExec should also be available in the same drop down with an on/off option.

/scripts/easyapache

Use the following command :

dd if=/dev/zero of= filename bs=1024 count=1024number of 0′s

Issue :

The server is mainly used for serving webpages and FTP. Certain things like DNS functions and email are not required as they are being handled externally. How can these be hidden from resellers/users?

Solution :

DNS, email or any other functionality can be handled through ‘Feature Lists’ in WHM. Just go to WHM >> Feature Manager. Edit/create a feature list and enable/disable functions as required. Assign this ‘feature list’ to the particular ‘package’ which is assigned to the accounts.

Issue :

The cronjob results in the following error :
/bin/sh: /usr/local/bandmin/bandmin: is a directory

This happens when the bandmin directory simply contains another bandmin directory instead of an executable script of the same name.

Run the following script and see if the issue persists :

# /scripts/bandminup –force

How to block emails from a specific address on a cPanel/WHM server using Exim ?

Solution :

This is fairly easy to achieve with Exim.
First you’ll need to find the system filter file for Exim. This can be found out through WHM >> Main >> Service Configuration >> Exim Configuration Editor.
Towards the middle of the page, under the section ‘Filters’ , you ‘ll find the path to the file.
Open that file via SSH using your favorite editor and add the following to it :

if first_delivery
and ( (“$h_from:” contains “emailtoblock@domainname.com”)
)
then fail
endif

If you would like a copy of the email to be sent to you after the message fails, use the following code :

if first_delivery
and ( (“$h_from:” contains “emailtoblock@domainname.com”)
)
then
unseen deliver “youremail@yourdomainname.com”
fail
endif

Make sure that you substitute the correct email addresses in the above code.

Issue :

Was able to login to all FTP accounts using the root password earlier but now it doesn’t seem to work. Where to check that?

Fix :

Go to WHM >> Main >> Service Configuration >> FTP Server Configuration.
At the bottom of the page, you’ll find an option as ‘Allow Logins with Root Password’
Make sure that it is set to ‘Yes’ and save the settings.

This should resolve the issue.
