If port 443 is open on a computer, that usually means web servers are waiting for a connection from a web browser. You can test whether the port is open by attempting to open an HTTPS connection to the computer using its domain name or IP address.

How can I tell if a port is listening on a Windows server

In order to check which application is listening on a port, you can use the following command from the command line:

1. For Microsoft Windows: netstat -ano | find "1234" | find "LISTEN" tasklist /fi "PID eq 1234"
2. For Linux: netstat -anpe | grep "1234" | grep "LISTEN"

What is port 443 normally used for

Port 443 is used explicitly for HTTPS services and hence is the standard port for HTTPS (encrypted) traffic. It is also called HTTPS port 443, so all the secured transactions are made using port 443. You might be surprised to know that almost 95% of the secured sites use port 443 for secure transfers.

Is it safe to port forward port 443

Whenever there is a request sent to your router (using the public IP address) with port 443 as the destination, your router directs this traffic directly to your device. You can securely log in and continue your development.

How do you check 443 port is enabled or not in Linux

How to check if a port is in use on Linux

1. Open the terminal application on Linux.
2. Type any one of the following command to check if a port is in use on Linux. sudo lsof -i -P -n | grep LISTEN.
3. Search for the TCP or UDP port description in /etc/services file on Linux: grep -E -w 'PORT_NUMBER_HERE/(tcp|udp)' /etc/services.

How do I make ports secure

How to Secure Open Ports

1. Access ports using a secure virtual private network (VPN). If a business needed something like RDP, ITS would use an encrypted VPN connection to access RDP instead of leaving it open to the internet.
2. Use multi-factor authentication.
3. Implement network segmentation.
4. Scan network ports regularly.

What service is using port 443 Windows

Based on the recommendations in this question, this is what I did:

1. From elevated cmd prompt ran netstat -a -n -o | findstr 443.
2. Identified the PID of the process listening on 443.
3. Used Process Explorer to identify the process from the PID.
4. In my case the application listening was vmwarehostd.exe.
