Hello,

Just to add to valuable information provided above by kuldeep, I'd like to let you know if you wish to enable the Jailed Shell Access to any of the cPanel account using SSH.

Just open the file "/etc/passwd' for editing in editor of your choice like vi

# vi /etc/passwd

Now look carefully the cpanel user name entry for which you want to enable the Jailed Shell Access, it will be something like this.

cpaneluser:x:880:875::/home/cpaneluser:/usr/local/cpanel/bin/noshell

Just change it to

cpaneluser:x:880:875::/home/cpaneluser:/usr/local/cpanel/bin/jailshell

and you are done..

Also to ensure the uninterrupted connections, please add the local machine ( internet ) Ip address ( of the machine from where you will access the server using SSH ) in server's Host Access Control List..

To do so just follow these steps

# vi /etc/hosts.allow and add the following line

sshd : XX.XX.XX.XX : allow

Note :: XX.XX.XX.XX should be replaced with the IP address of the machine you will use to access the account using SSH

May I ask, What are the features that are available in the Jailed Shell?

Basically, the main purpose of jailed shell environment is to provide the user with a limited and restrictive environment. In that environment the user can do whatever he/she want. The idea behind restricting is that the user can't do much damage to the server if they are restricted. Usually, in shared hosting most of the web hosting companies don't provide shell access to the clients as thousands of websites are hosted on a single server.
