For cPanel & WHM 11.44

How do I delete an account?

You can delete an account with WHM's Terminate Account interface (Home >> Account Functions >> Terminate an Account).

Important:

You cannot reverse this process. Back up the account before you delete it so that you can retrieve any of the files from that account.

How can I find out where all of a user's files are?

A discrepancy between quotas and du -sh /home/username command might indicate that that user's UID owns some other files on the system.

To find these, run the find / -user username -ls command on the command line.

  • The output is a long list of all files that the user owns.
  • Redirect the output to a file.

I just created a new account. Why does it show disk space usage?

A terminated or deleted account may still have files that the previous user's UID owns. When you create a new account, the system assigns it the next available UID, which may come from a terminated account. The new account assumes ownership of all files that the previous user owns. This gives the appearance that the new user is already over quota, even though they have not uploaded anything.

Also, tarballs such as .tgz, .tar, and .tar.gz may have files that are owned by the user that tarred them. When those files are untarred on your server, they are assigned to the ownership of the account which has that UID.

How can I uninstall cPanel & WHM?

The best way to uninstall cPanel & WHM is to reformat your server.

If you will not continue to use cPanel & WHM, we recommend that you reinstall your operating system in order to return your server to a default setting.

  • Opera© 12
    • There are known problems with the Opera browser. We recommend that Opera users disable browser caching or use a different browser as a workaround.

As a web hosting provider, can I create a custom login page for my customers to log in to cPanel, WHM, or webmail?

Yes. We offer sample source code that you can use to integrate a customized login page to an existing website. This source code is in PHP and is available in our PHP documentation.

Does cPanel & WHM include anti-virus protection?

Yes. cPanel & WHM comes with ClamAV Scanner (Home >> Plugins >> ClamAV Scanner).

Does cPanel & WHM include web statistics programs?

cPanel & WHM comes with the following web statistics software:

  • AWStats
  • Webalizer
  • Logaholic
  • Analog

You can enable your preferred web statistics software in WHM's Statistics Software Configuration interface (Home >> Server Configuration >> Statistics Software Configuration).

When I create a domain, are web statistics automatically generated?

Yes. You can set the interval at which your web statistics software will update in the Schedule Configuration section in the Statistics Software Configuration interface (Home >> Server Configuration >> Statistics Software Configuration).

Note

Statistics are not available on the newly created domain until after the specified interval.

How can I fix quotas that do not work?

Important:

  • Quotas do not limit updates that a user can make to a MySQL or PostgreSQL database.
  • Quotas that include database space only affects cPanel-related functions.
  • Processes that the system runs, such as PHP scripts that create files, can create user-owned files until the number of files reaches the quota. This is because the kernel-enforced quota is not aware of cPanel settings.

Check for quota support on the mounted filesystems:

For Linux:

mount
/dev/hda6 on /var type ext3 (rw,usrquota)
/etc/fstab
/var /var ext3 defaults,usrquota 1 2

 

If the entries are not in the /etc/fstab file, use a text editor to add them. If they are present, verify that there is support for quotas in the kernel and that any relevant modules are loaded.

Check that the quota files are present and are not zero byte files:

For Linux:

-rwxr--r-- 1 root root 8192 Dec 26 20:18 aquota.user
-rwxr--r-- 1 root root 2097120 Apr 30 04:19 quota.user

 

If these files do not exist, run the /scripts/initquotas script. If they do exist, but quotas do not work, you can either delete the quota files and run the initquotas script or run the /scripts/fixquotas script. 

The repquota -a command prints out the soft and hard limits with grace periods for all users.

If quotas still do not report anything in WHM or cPanel, access the System section in WHM's Tweak Settings interface (Home >> Server Configuration >> Tweak Settings). Set the Cache disk quota information option to Off. Then click Save at the bottom of the interface.

How can I set up a default page that the server generates when I create a new domain?

Set up a default page in the /root/cpanel3-skel/public_html/ directory. This is the default page for all accounts that you add.

Does cPanel & WHM support multiple levels of permissions?

Yes. cPanel & WHM supports root users that can create or modify any domain and have access to all features of the cPanel and WHM interfaces.

We also support resellers, who intend to manage their own customer's accounts. However, you can easily modify reseller access so that they only have privileges to perform tasks such as the suspension or unsuspension of domains. Resellers have access to the cPanel interface and a limited subset of the functionality of the WHM interface.

Lastly, there is the hosting account owner, who has an account in the cPanel interface and can manage most aspects of a website by themselves (within boundaries that the reseller or a user with root access sets).

When a user logs in to cPanel, they receive the following message: "There is a problem with this website's security certificate". How do I stop this message?

You can change the certificates for cPanel & WHM with WHM's Manage Service SSL Certificates interface (Home >> Service Configuration >> Manage Service SSL Certificates).

You will need to replace the self-signed certificate with one that common browsers trust. To purchase an SSL certificate through WHM, use the Purchase & Install SSL Certificate interface (Home >> SSL/TLS >> Purchase and Install SSL Certificates).

Is there a way to access webmail, cPanel, and WHM from behind a firewall?

WHM allows your customers to access the following services from behind a firewall, through port 80:

  • cpanel.example.com — The customer's cPanel account.
  • whm.example.com — The customer's WHM account.
  • webdisk.example.com — The customer's Web Disk account.
  • webmail.example.com — The customer's webmail account.

Note:

 In these examples, example.com stands for the customer's domain.

 

To enable this feature, select the following options in WHM's Tweak Settings interface (Home >> Server Configuration >> Tweak Settings).

  • Proxy subdomains
  • Proxy subdomain creation

You can also use the /scripts/proxydomains script to manually reconfigure the DNS entries.

Note

To learn more, read our Tweak Settings documentation.

Can I run cPanel behind NAT?

Yes, cPanel & WHM supports 1:1 NAT configurations. For more information, read our 1:1 NAT documentation.

Previous versions of cPanel & WHM allowed you to run cPanel & WHM behind a NAT firewall. However, the system has changed. If you use more than one server behind the NAT, which means that more than one appears from behind the same public IP address, the license server will lock the public IP address out to prevent abuse.

How do I change the maximum number of IMAP connections per IP address?

You can change the value of the Maximum IMAP Connections Per IP setting in WHM's Mailserver Configuration interface (Home >> Service Configuration >> Mailserver Configuration).

Note

IMAP settings are the same for both Courier and Dovecot.

How do I change the maximum number of POP3 connections per IP address?

You can change the value of the Maximum POP3 Connections Per IP setting in WHM's Mailserver Configuration interface (Home >> Service Configuration >> Mailserver Configuration).

Note

POP3 settings are the same for both Courier and Dovecot.

How do I change the maximum number of simultaneous incoming SMTP calls?

You can change the value of the smtp_accept_max setting in WHM's Exim Advanced Editor interface (Home >> Service Configuration >> Exim Configuration Manager >> Advanced Editor).
