Plesk is an administration panel developed by swsoft. A demonstration version is available online. The official documentation for Plesk can also be found at the official site.

If your got the following message: “Can not reach the license server: Unable to connect to the license server”

Parallels Plesk Panel connects itself to the license server of Parallels (Key Administrator) using port 5224 to verify the validity of the license.
Make sure the connection to ka.parallels.com:5224 isn’t blocked at your Parallels Plesk Panel server or at any part of your network.

You can use the following commands to test the connectivity:

nmap -P0 -p5224 ka.parallels.com
telnet ka.parallels.com 5224
traceroute ka.parallels.com

To cancel the Plesk license use the “Services list” in the billing section of your management console. If you cancel a Plesk subscription, the whole month is due.

An anonymous attack can compromise your Plesk server and you MUST update your panel to fix this issue.

To connect yourself to the panel on a freshly installed server, go to:

 http://sd-YOUR_SERVER_NUMBER.dedibox.fr:8443

ou

 http://IP-of-your-server:8443

The default login is “admin” and the password you have specified during the installation.

The license file for Plesk is available in the management console. Click on the link “ Download the key ” to download the license key and import it into your Plesk Panel.

To do an update of Parallels Plesk (For example from version 9 to 10), connect yourself to the management console.

Go to the Plesk section of your Dedibox and click on the link “Upgrade to version 10”.

This is not required anymore since version 11. You can do the upgrade directly in your Plesk panel without changing the license key.

You can update Plesk using the command line. Connect as ‘root’ to your server in SSH (Note: You should update the OS before you run this.). Type the following command:

/usr/local/psa/admin/sbin/autoinstaller

In another terminal you can type the following command to observe the update:

tail -f /tmp/autoinstaller3.log

To update the number of domains allowed in your Plesk panel (for example to change from 10 to 100 domains), connect yourself to your management console.

Go to the Plesk section of your dedicated server.

Click on the link “More domains” next to your license to upgrade the number of domains allowed in your panel.

To make sure your Plesk license can be validated, you have to make sure that the following IP’s and ports are reachable and not blocked in your firewall configuration:

• 195.214.233.80:522
• 195.214.233.80:443
• 195.214.233.81:5224
• 195.214.233.81:443
• 195.214.233.82:5224
• 195.214.233.82:443

You need to connect as root to your server. Install GD2 using the following commands:

aptitude update && aptitude install php4-gd

Please note that this will only work if Plesk is using PHP4 (If you use PHP5, replace php4-gd with php5-gd)

Restart apache:

/etc/init.d/apache2 restart

GD2 is available now.

If this is not the case, follow these steps:

Open your php.ini

vim /etc/php4/apache2/php.ini

Add this line at the end of the file:

extension=gd.so

Then restart apache2:

/etc/init.d/apache2 restart

If you panel is no longer available (but your other services are available), connect yourself as root to your Dedibox and type:

/etc/init.d/psa stop

then

/etc/init.d/psa start

Your panel will be available again. You may also consult the logs of Plesk

Some providers may restrict the access to port 25 direct in the ADSL box.

If you can not connect to port 25 of your server, it is possible to change it to antoher, for example 15052

You need to edit the file:

/etc/services

and add a line:

smtp_alt 15052/tcp # new SMTP port

You have then to type:

cp /etc/xinetd.d/smtp_psa /etc/xinetd.d/smtp_psa_alt

and edit the file

/etc/xinetd.d/smtp_psa_alt

modify the first line like

service smtp_alt

You need to restart xinetd

/etc/init.d/xinetd restart

now SMTP connections are possible using the standard ports and 15052.
