How to: Activate SNI on a Plesk server

sshIf you are running Plesk for Windows then you can activate SNI in Tools & Settings > Server Settings. Plesk for Linux always has SNI enabled if it is supported.

Most modern web browsers, starting with IE 7, Firefox 2.0, Opera 8.0, and Chrome 1.0, support SNI, unless they are run on Windows XP.

Open up a terminal session and let’s find out if SNI is active on your server:

# cat /etc/psa/psa.conf | grep SNI


If you see this, then you are in business. If not, then unfortunately there is nothing you can do. You are likely running Centos 5.8 or older. You’ll need to upgrade to Centos 6.

Plesk Server Upgrades – Incoming


So that we can continue to provide high levels of performance to all our hosting clients we are planning a number of upgrades to both server hardware and control panel software for 2015.

Plesk 9 – We know many of you love this old panel but unfortunately it’s time to say goodbye to it. All Plesk 9 servers will be upgraded to Plesk 11.5 during Q1 2015. Plesk 11.5 provide higher performance, security and a multitude of new features over Plesk 9. The server hardware will be completely replaced with current high performance hardware.

Plesk 10 – The remaining Plesk 10 servers will be upgraded to Plesk 11.5 during Q1 2015. The server hardware will be completely replaced with current high performance hardware.

Plesk 11/11.5 – Besides security and panel updates, these servers will remain as they are.

Plesk 12 – From Q2 2015 we will be rolling out Plesk 12 for all new accounts. We will offer free migrations from Plesk 11/11.5 to Plesk 12 when requested.

We are committed to ensure we have the highest performance and security available for all of our clients. We will update you directly when your server is affected with specific upgrade dates. If you have any questions please do not hesitate to contact the Helpdesk.

How to: Restrict use of Perl, CGI and insecure Scripting

sshWith Plesk 12 you can create a “preset” which limits the type of scripting that can be assigned by your clients. This can help with the problem where you do not allow Perl or CGI but your Reseller clients can create service plans that allow these restricted services.

To prevent this from occurring, you can create presets which will not allow your clients to override these scripting options.

The file you need to edit

nano /usr/local/psa/admin/conf/site_isolation_settings.ini

In general, your PHP will always be switched on. Your PHP should be handled by FastCGI (for performance and security). Set Perl and CGI to “off” as follows

; The section describes allowed hosting options
php = on
php_handler_type = fastcgi
python = off
perl = off
cgi = off;
;fastcgi = any
;miva = off
;ssi = any
;ssl = any
;shell = /usr/local/psa/bin/chrootsh
;asp = any
;php_safe_mode = off
coldfusion = off

You can easily restore the original configuration files whenever required

cp /usr/local/psa/admin/conf/site_isolation_settings.ini.default /usr/local/psa/admin/conf/site_isolation_settings.ini

As a Plesk 12 admin, you can override these settings for any subscription. This simply eliminates these scripting options from showing as options to your clients.
