cpanel Could not edit password file : Permission denied

Issue: I got this error while changing the email account’s password through cpanel.

Solution:

Check permissions of passwd file in /home/username/etc/domain.com/

The correct permissions should be the following:

-rw-r–r– 1 username mail  196 Dec  3  2005 passwd
-r–r–r– 1 username mail 1088 Dec  3  2005 passwd,v

Try to change the password now.

Load due to a particular user in the server

Whenever the load in the server increases due to a particular user in the server, we can solve it using the following steps.

Find the domain owned by the user:

grep username /etc/userdomains

use the following command after you get the domain name:

less /usr/local/apache/domlogs/domain.com | awk ‘{print $1}’ | sort | uniq -c | sort -n

Note: use the domain name in the field of  “domain.com” in the above command

This will give the ip and number of connections in the descending order.

Example:

12000  75.52.110.145

29172  66.249.68.183

458262  208.55.16.55

You can block the above Ip’s since there is too many connection from the above Ip’s.

 

You can use either csf or iptables.

csf -d >IP>

OR

iptables -A INPUT -s <ip> -j DROP

Solution :

The issue was with iproute package. The package got updated automatically and it was not excluded in yum updates. To fix the issue, you need to downgrade the package iproute.

Login to the main node and download the RPM as per the arch.

[root@node9 ~]# wget http://repo.smartservermanagement.com/misc/iproute-2.6.32-23.el6.x86_64.rpm

Then copy it to vps.

[root@node9 ~]# cp iproute-2.6.32-23.el6.x86_64.rpm /vz/private/<vpsid>/fs/root/

After that enter to the vps

vzctl enter <vpsid>

Then run the following command.

rpm -qa |grep iproute

You will get the current iproute package versiom

ie;

root@server [~]# rpm -qa |grep iproute

iproute-2.6.32-31.el6.x86_64

Now remove the old package and install newly downloaded version.

root@server [/]# rpm -e iproute-2.6.32-31.el6.x86_64 –nodeps

Go to the location where you copy the file from node and install it.

root@server [/]# rpm -ivh iproute-2.6.32-23.el6.x86_64.rpm

 

Try to restart network now and run ifconfig after that.

In order to prevent conflicts, Tweak Settings may not be altered while a cPanel & WHM® update is in progress

Issue : I got this error while accessing Tweak Settings through WHM.

Solution :

Firstly check if really upcp is running, you can check with the command :

 ps axfwwwu | grep cPanel\ Update

If yes then let it be done otherwise, the issue may raised due to a new version of cpanel was downloaded, but
either upcp is still in progress or failed and is incomplete.

And the entry made at file /usr/local/cpanel/upgrade_in_progress.txt

you just needs to move/remove that file and now you can access Tweak Settings

 

That’s all………..!!!!!!!
