About telnet

Telnet is software that allows users to remotely access another computer such as a server, network device, or other computer. With telnet, users can connect to a device or computer, manage a network device, setup a device, transfer files, etc.

Tip: Today, you should be using SSH instead of telnet for security reasons unless SSH is not an option.

  • See the telnet definition for further information about the term telnet as well as related dictionary terms.

Telnet programs

There are also numerous third-party telnet and SSH programs available for connecting to remote computers. Users who use telnet often or want or need additional features should consider a third-party telnet program.

Unix and Linux telnet

Most Unix-like operating systems including Ubuntu, Debian, Solaris, OS X and FreeBSD include a telnet binary which can be used to connect to a remote host with the telnet protocol. At a terminal prompt, run the command:

telnet hostname

...to connect to the remote system identified by hostname. You can also run:

telnet

...to start a telnet prompt, where you can enter telnet commands. For instance, at the telnet prompt, type:

open hostname

...to open a connection to the remote system hostname.

For a list of common telnet commands, see our Unix and Linux telnet command page.

What next

If done properly, you will either get to a prompt where you can perform the commands necessary, or should receive a prompt for the username and password. If you have an account setup on the computer you are attempting to connect to, enter it now. If you do not have an account for the server, you can try connecting anonymously by entering your name and e-mail address as shown below.

username: anonymous
password: [email protected]

If this feature is supported on the server you would then be logged in anonymously to that server.
