How can I test the connection to another server port in Linux?
You can use the telnet command to test the connection to another server’s port. Here are the specific steps:
- Open the terminal or command prompt.
- Connect to a specific IP address using Telnet on a specified port number.
- Press the Enter key to establish the connection.
- Attempting to connect to IP_ADDRESS…
Successfully connected to IP_ADDRESS.
Use the escape character ‘^]’ to exit. - Attempting to connect to the IP address…
telnet: Could not establish connection with remote host: Connection refused - Press Ctrl + ] key, type quit command, and press Enter key again to exit the telnet session.
By following the steps above, you can test connecting to a specific port on another server. Make sure the port on the target server is open and that the firewall or other network security settings do not prevent the connection.
