When using Telnet to connect to a remote server or device, you may need to view all lines of responses from the command you entered. By default, Telnet only displays a single line of response at a time, which can be inconvenient when you want to see the complete output. In this article, we will explore how to print all lines of responses of a command in Telnet.
Step 1: Open Telnet
To get started, open the Telnet application on your computer. Telnet is a built-in command-line tool available on most operating systems, including Windows, macOS, and Linux.
Step 2: Connect to the Remote Server or Device
Once Telnet is open, you need to establish a connection to the remote server or device. To do this, type the following command:
telnet [IP address or hostname] [port]
Replace [IP address or hostname] with the IP address or hostname of the server or device you want to connect to. If the server or device uses a non-standard port, replace [port] with the appropriate port number. Press Enter to execute the command.
Step 3: Enter the Command
After successfully connecting to the remote server or device, you will see a command prompt. This prompt indicates that you can now enter commands to interact with the server or device. Type the command you want to execute and press Enter.
Step 4: Enable Line Mode
By default, Telnet operates in character mode, which means it only displays a single line of response at a time. To enable line mode and view all lines of response, type the following command:
mode line
Press Enter to execute the command. This will switch Telnet to line mode, allowing you to see the entire output of the command.
Step 5: Execute the Command Again
After enabling line mode, you need to execute the command again to see the complete output. Simply re-enter the command and press Enter.
Now, Telnet will display all lines of response generated by the command, allowing you to view the complete output without any limitations.
Step 6: Exit Telnet
Once you have finished viewing the output and interacting with the remote server or device, you can exit Telnet. To do this, type the following command:
quit
Press Enter to execute the command and close the Telnet session.
Congratulations! You have successfully learned how to print all lines of responses of a command in Telnet. By enabling line mode, you can now view the complete output of commands executed through Telnet.
Conclusion
Telnet is a powerful tool for remotely accessing servers and devices. By default, Telnet displays only a single line of response at a time, which can be inconvenient when you need to see the complete output. However, by enabling line mode, you can easily view all lines of responses generated by a command. This allows for a more efficient and effective troubleshooting or configuration process.
