How to view the results of the telnet command in Linux?

In Linux, the telnet command is used to connect to a remote server or device and perform basic network communication tests. The results of the telnet command will be displayed in the terminal window.

Here are several possible outcomes of the telnet command:

1. Successful connection: Once successfully connected to the target host or device, the telnet command will display a welcome message or login prompt, indicating that the connection has been established. You can then start entering commands or sending data in the telnet session.
2. Connection Timeout: If a connection timeout occurs, it means that a connection cannot be established with the target host or device. This could be due to network issues, the target host being unreachable, or the telnet service not being enabled on the target host.
3. Connection refused: If a connection is refused, it means that the target host or device has denied the telnet connection. This could be due to the telnet service not being enabled on the target host, a firewall blocking the telnet connection, or the target host not allowing your IP address to connect.
4. Connection interrupted: If the connection is interrupted, it means that the connection to the target host or device has been disconnected. This could be due to network issues, the telnet service on the target host being stopped, or the target device disconnecting.

Whether the telnet connection is successful or not, you can determine the result of the telnet command through the output information in the terminal window.
