Telnet is a handy application that has been around for decades. You can use it to connect to remote servers for various reasons, such as managing a machine remotely via a Telnet server or managing the results of a Web server.

To step

1. Open Terminal on your Mac, in the folder Tools below Programs.
   • This is the same as the command prompt in Windows. However, because OS X is based on UNIX and not MS-DOS, the commands are different.

2. Select from the Shell-menu New remote connection.
3. Enter the host name or IP address. In the field at the bottom of the window New connection as indicated below, enter the address of the server you want to connect to.
   • Note that you need an account to log in.
4. click on To connect.
5. You will be asked for your password. Your keystrokes are not displayed for security reasons.
6. Save your settings. Click on the + under the column Server.
7. Enter the host name or IP address of the server in the displayed welcome screen.
8. click on OK.
9. Type the userID in the User field, click Connect and your data will be saved.

• Incoming connections and errors during the authentication process are usually tracked by most servers, so avoid using Telnet for obscure purposes.
