waiting for an SSH connection request. We can detect if the SSH server is running, but it doesn’t give info if an SSH connection is active. We can verify that if the SSH port is currently open.
For example, HTTP runs on port 80 by default, serving up websites, and when you SSH to a computer, you’re probably connecting on port 22, which is the default for the SSH service. The port tells the computer what process you’re trying to reach. A service can be set to respond on...
A free open port check tool used to detect open ports on your connection. Test if port forwarding is correctly setup or if your port is being blocked by your firewall or ISP.
For example, if you are running an Apache or Ngnix based web server, the port in use should be 80 or 443. Checking the ports will confirm that. Similarly, you can check which port is being used by SMTP or SSH or some other services. Knowing which ports are in use can be helpful wh...

If you want to avoid "guessing", use -ssh-hostname or --pg-hostname. Also, you can define a specific way to connect: SSH or psql: --ssh-hostname db2.vpn.local - SSH will be used for the connection. SSH port can be defined as well with option --ssh-port. --pg-hostname db2...
If both is the case, a custom .NET check can be set up to perform an SSH command, either cyclically, on an event (e.g. change in a system variable) or on demand. For the task of opening an SSH connection and passing commands comfortably, the open-source, free ...
While this checks if a port is open in Linux, it can generate a lot of output. You can control the output using netstat’s command-line options. For example, to view the PID and program name for a system’s listening TCP connections, run netstat with the following command-line options:...
