What is an express transfer?
An express transfer transfers the requested cPanel account(s) and performs the following actions on the source server:
- Updates the account's A record to point to the destination server.
- Changes the domain's nameserver entry to point to the destination server. This is only done when appropriate.
- Updates the mail databases to point to the destination server.
- Adds a redirect for the Account Moved page (
cgi-sys/movingpage.cgi) for the following file extensions:
- Blocks SSH and FTP logins to the source server for accounts that were transferred.
Changes are handled on the source server via
How do I block an IP address from my server?
You can block IP addresses with WHM's Host Access Control
feature ( Home >> Security Center >> Host Access Control
How do I clear a full partition?
There are a few possible solutions.
directory fills up first. This is because the
directory holds all of the system logs.
- To see the directory or log that takes up the most space, run the following commands:
- This shows the space used and available in each directory, as well as the file sizes of each file in the current directory.
- Examine the output and determine which directory takes up all the space. Change to that directory with the
cd directory command.
- Run the following commands again:
- Follow this pattern until you find the files that take up the space.
- When you find the directory or file that takes up the most space, you can either delete the files or save some of the most recent entries. Run the following to save the most recent entries:
tail -5000 filename > filename.new
mv filename.new filename
- Restart the service that created the file, to release its file lock.
directory also fills up due to Apache. To look at the Apache logs:
files can be very large. At this point, you can delete them or use the
set of commands listed above.
How do I restart a daemon ?
- You can restart most services in WHM (Home >> Restart Services).
- You may need to restart them from the shell.
- You must be logged in as
root to do this.
- All standard Linux services, such as HTTP, FTP, Exim, cPanel & WHM, MySQL, etc, have
init scripts in
root@host [~]# ls /etc/rc.d/init.d/
./ atd* exim* httpd.tmpeditlib kdcrotate* named* nscd* rawdevices* snmpd* yppasswdd*
../ autofs* filelimits* identd* keytable* netfs* portmap* rstatd* sshd* ypserv*
anacron* bandmin* functions* ipaliases* killall* network* portsentry* rusersd* syslog* ypxfrd*
antirelayd* chkservd* gpm* ipchains* kudzu* nfs* proftpd* rwalld* xfs*
apmd* cpanel3* halt* iptables* lpd* nfslock* radvd* rwhod* xinetd*
arpwatch* crond* httpd@ isdn* mysql* nofsck* random* single* ypbind*
This is typical of what you will find in this directory. The main ones you should be concerned with are:
- cpanel3 — Starts and stops cPanel and WHM. This includes cppop and cluster management services as well.
- exim — Starts and stops the exim mail server.
- httpd — Starts and stops the Apache web server.
- mysql — Starts and stops the MySQL database server.
- named — Starts and stops the BIND DNS server.
- proftpd — Starts and stops the ProFTPd or Pure-FTPd (this depends on which is enabled) FTP server.
You can run these scripts. For example, if named/BIND is down and you need to restart it, as
- You should see it start up, with a green [OK] message on the left side of the shell/terminal window.
- If you see a red [FAILED] message, check the message log.
You should be able to see the error. If you cannot fix it yourself, you should submit a ticket
. Some of these services have more options than just "start" and "stop,".
- For example, if you have several domains that are on your DNS server and you do not want to stop and restart named just because you edited one domain, type:
If you make a minor change to the
file, but do not want to restart it, type:
/etc/rc.d/init.d/httpd graceful to do a graceful restart.
- Note: A graceful restart finishes current requests before it kills the child processes.

How does cPanel move things from Alabanza servers?
Does it redo the folder structure into public_html instead of domain-www?
Does it move the email files over from /home/user/domain-mail/emailaddressfile to /home/user/mail/emailaddress/emailaddressfile?
Does it keep all of the email settings such as forwarders, auto replies, etc...?
Does it also grab the parked domain names?
How do I manually move an account to another server?
When an account is too large to move with the web browser, follow these steps to move the account:
In this example, the domain will be
and the username will be
mkdir /home/cptemp to make a temporary directory on
/home where you can store the account's files while you copy them.
- Tar and gzip the
public_html directory, and move that over with
tar czvf public_html_dom.tgz public_html
mv public_html_dom.tgz /home/cptemp/
mv public_html /home/cptemp/
- Move the site's weblogs:
mv domain.com.gz /home/cptemp/
- Now that all necessary files are in
/home/cptemp/, you can move the account over in WHM.
- Go back to
scp the files to their new home:
scp public_html_dom.tgz firstname.lastname@example.org:/home/dom/
- Enter the
root password for the new server and let it copy the file over.
scp domain.com.gz email@example.com:/usr/local/apache/domlogs/
- Enter the required login information.
- Go to the new server and unpack the two large files you just moved:
gzip -d domain.com.gz
tar xzvf public_html_dom.tgz
Where is the Pure-FTPd configuration file?
How do I enable anonymous uploads with Pure-FTPd?

Some older drives/motherboards have a problem with this, so you should ask your data center to be sure it is ok before you enable DMA on your drives.
Can I change the Home and Logout buttons through WHM branding?
These cannot be changed through branding. You will need to edit the WHM theme to modify buttons, background colors, etc.
How do I fix the error "License File Expired"?
Your server needs to be able to communicate with the licensing servers.
To confirm that your server's main IP address matches the IP address that is stored in the cPanel licensing servers, follow these steps:
- Run the following as the
- curl http://www.cpanel.net/apps/myip/
- If the IP addresses do not match, you will need to do one of the following:
- Change the routing in your server and network to route outbound traffic from the IP address that is licensed.
- Change the IP address on the license to match the IP address returned by the curl command.
- Check the license on http://verify.cpanel.net to ensure that it is valid. If it is not, please contact your license provider.
- If your license is valid, run the following as the
- rdate -s rdate.cpanel.net
- Ensure that your server can query the
root nameservers and has a valid hostname. If you need assistance with this, contact your hosting provider.
If these steps did not fix the issue, contact your license provider.

Will cPanel continue to support FrontPage® extensions? How about on Apache 2?
Since Microsoft® discontinued support for mod_frontpage extensions on Linux servers in 2006, we no longer include FrontPage by default in cPanel & WHM. FrontPage has been removed from EasyApache. FrontPage extensions are still available as a Custom Module
(“Opt Mods”) for EasyApache; however, we strongly
discourage its use and it is only compatible with Apache version 2.2. Some other methods you can use to publish content are WebDAV or FTP.

Why does Munin fail to update?
Munin is a cPanel Plugin that displays information about CPU, Exim, Apache, MySQL usage, and other information, with
. If it fails to update, there is likely a permissions issue.
First, check to make sure that cron is running, and that there is a crontab entry for Munin. Next, check
. The files in both directories must be owned by
. If the files in
are not owned by
, the log files will be updated, but the graphs that are displayed by Munin will not be updated.
This permissions issue can be corrected when you run the following commands as
chown -R munin:munin /var/log/munin
chown -R munin:munin /var/lib/munin
Now run Munin manually from the command line:
sudo -u munin munin-cron
You should see entries added to
, and no errors in the log file. The graphs should be updated when you refresh the Munin display in WHM.
The weekly graphs may not be updated immediately. These will be updated at the appointed time configured in the crontab.

Why does my Ruby on Rails install not work?
cPanel uses the standard set of tools that Ruby on Rails provides. This makes troubleshooting relatively easy.
error_log often shows what is wrong with the Rails installation.
- If it is an application-specific issue, mongrel maintains its own error log at
- If an application starts and fails without anything in the
error_log, there will probably be an indication of the problem in here as well.
- You may need to install some gems. You can check which gems are installed via a "gem query":
- Note: If any of these gems are not present, you can install them via
gem install <name>.
- If the wrong version is installed, run
Once you have verified all of this and the application still does not start correctly, you can start the mongrel server manually with the
mongrel_rails start -p -d -e production -P log/mongrel.pid
command from the Rails application's base directory as the user who owns the Rails application.
The port can be found in
If you are still unable to fix your Rails installation, open a ticket with either your data center or with cPanel.
I just created a new account. Why does it show that disk space is already used?
- When a user has been deleted from the system (terminated account), they may still have files owned by that old user's UID. When a new account is created, the system assigns it the next availble UID, which is usually that of a terminated account. Thus the new account assumes ownership of all files owned by that old user, and gives the appearance that the user is already over quota though nothing has been uploaded.
- Tarballs (
.tar.gz) may have files owned by the user they were tarred up with on a separate system. When untarred on your server, they are assigned ownership of whatever account has that UID.
For more information, read our Quotas Documentation
How can I set up a default page that is generated when any new domain is created on the server?
You can set up a default site in the
directory, and it will be the default website for all accounts added afterwards.
How does yum need to be configured to work with cPanel?
cPanel & WHM requires that certain packages be excluded due to the fact that cPanel handles its own installations of services that are separate from what the distributors provide. If you have modified the
file, you will want to ensure that the following excludes exist:
We also strongly
recommend that you use only the vendor-provided distributions, because cPanel is tested only with these packages. 3rd-party repositories such as RPMForge can replace vital parts of the system that cPanel relies on, and cause unexpected results.
Is there a way to access webmail, cPanel, and WHM from behind a firewall?
WHM includes a feature that lets your customers access the following from behind a firewall with 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 On
for the follwing Tweak Settings
options in WHM:
- Proxy subdomains
- Proxy subdomain creation
To learn more about these options, read our Tweak Settings documentation
You can also use
to reconfigure the DNS entries manually.
Can I run cPanel behind NAT?
Short answer: No, it is not supported.
It was once semi-possible to run cPanel behind a NAT firewall. However, the system has changed somewhat, so that if you use more than one server behind the NAT (more than one appears from behind the same public IP), the license server will lock the public IP out to prevent abuse.
This behavior may change in future versions.
Where do I go to find out when a new build of cPanel is released?
Some builds are released quicker than others. For example, CURRENT builds are released quicker than RELEASE builds, and EDGE builds are released quicker than CURRENT Builds.
To find the latest builds, go to http://httpupdate.cpanel.net
, and look for your operating system.
I use the APF firewall rules on my server; which ports should I allow?
