I know this is not related to Unix but can anyone tell me command or method to check if port 3389 is open or not on my server? It means a good help to solve issue for me.
Try netstat command on Windows system. Open Windows command prompt and type the following commands:
netstat -aon | find /i "listening"
See if port 3389 is open
netstat -aon | find /i "listening" | find "3389"
Where netstat options are as follows:
- -a : Displays all active TCP connections and the TCP and UDP ports on which the computer is listening.
- -o : Displays active TCP connections and includes the process ID (PID) for each connection.
- -n : Disable DNS lookup
- find : Find command act as filtering with shell pipe
Another option is to use the nmap command from your Linux or Unix box to scan for open ports. See
