cPanel contains a Java application called Java Telnet Applet which lets you connect to the web server using a Telnet connection through cPanel. This application can be accessed by clicking the appropriate button at the SSH/Shell Access main screen.
A pop-up window will open that contains the Telnet Java application. Another pop-up, requesting login information, will also be opened. Enter your username and password.
Upon successfully logging in, a connection will be made, allowing the manipulation of your web server through the CLI. Please note that keys cannot be used as an authentication method; a username and password are required.
Note: There are a number of specific Telnet commands with which you may need to familiarize yourself. Please consult your favorite search engine for more information regarding Telnet and your operating system’s commands. It is also recommended that SSH be used in place of Telnet when possible, as an SSH connection is inherently more secure.
