Prerequisites

Before you begin, make sure you have the following:

Step 4: Use Telnet Commands

Once connected, you can use various Telnet commands to interact with the remote host. Some common Telnet commands include:

• open - Open a connection to a remote host
• close - Close the current Telnet session
• quit - Exit Telnet
• send - Send data to the remote host

Step 5: Disconnect from the Remote Host
