To verify if port 3306 is open, you can use NetStat, CurrPorts, or PortQry.We recommend NetStat, as you won't have to download new software for this. Run the Command Prompt as administrator. Type the command: netstat -ab and hit Enter. Wait for the results to load. Port names will be listed next to the local IP address. Just look for port 3306. You can press Ctrl + F and type 3306 in the word box to search for it. If the port is open, it will show in the results as LISTENING.To check if port 3306 is open via CurrPorts, just sort by Local Port, then find port 3306. If the port is available, it will show in the list.To use PortQry.exe to find port 3306, use the Command Prompt. Type -e [3306], then press Enter." } }, "@type": "Question", "name": "What are Predefined Services in PortQueryUI?", "acceptedAnswer": "@type": "Answer", "text": "Predefined Services offers details on a small handful of predefined services such as Domains and Trusts, Networking, Exchange Server, etc. The option queries all required ports for the specified services and displays them in the window of the UI.For those who don't know where Predefined Services resides, it is directly under the Help tab and in the UI.

Get The List Of Open Ports In Windows ^NEW^
One of the simplest ways to check for open ports is to use NetStat.exe. You can find this tool in the System32 folder on Windows 10. With NetStat, you can see open ports or ports that a specific host uses.
Netstat is short for network statistics. It shows protocol statistics and the current TCP and IP network connections. The two commands needed to identify open ports in netstat -ab and netstat -aon.
The Help tab option immediately displays all predefined services without testing any ports. It is a quick reference to each port name, value, and protocol used for each listed service.
2. Run netstat -a to find all of the listening and established connections on the PC. By default, netstat only returns listening ports. Using the -a parameter tells netstat to return listening and established connections.
using the 'Find' command allows you to filter the results. find /i "listening" will display only ports that are 'Listening'. Note, you need the /i to ignore case, otherwise you would type find "LISTENING". find "port" will limit the results to only those containing the specific port number. Note, on this it will also filter in results that have the port number anywhere in the response string.
But it seems that it doesn't work. When my USB to COM gateway is connected to the PC (I see the COM5 in the Device Manager), this COM port isn't included in the list returned by list_ports.comports(). Instead I only get COM4 which seems to be connected to a modem (I don't see it in the COM&LPT section of Device Manager)!
A possible refinement to Thomas's excellent answer is to have Linux and possibly OSX also try to open ports and return only those which could be opened. This is because Linux, at least, lists a boatload of ports as files in /dev/ which aren't connected to anything. If you're running in a terminal, /dev/tty is the terminal in which you're working and opening and closing it can goof up your command line, so the glob is designed to not do that. Code:
Many administrators usually use the netstat console tool or graphic TCPView to display information about active TCP/IP connections and open TCP ports in Windows. Instead of netstat, you can use the Get-NetTCPConnection cmdlet in PowerShell to get information about active network connections in Windows, open TCP ports, and running processes that are using the TCP/IP protocol. PowerShell makes it easy to write complex scripts to get information and monitor open TCP ports, processes, and established network connections. (adsbygoogle = window.adsbygoogle []).push();
Like netstat, the command has displayed the list of all active connections with local and remote IP addresses, ports, connection state (Listen, Established Internet, TimeWait, Bound, CloseWait, SynReceived, SynSent), and process ID (PID) that is using this TCP connection.
If you are running a firewall on the computer where you will be installing Tableau Server, then you will need to open the following default ports for Tableau Server traffic. All port numbers, except 443 can be changed.
Because these ports do not use the dynamic port mapping system, they do not show up in the output of the tsm topology list-ports command. To see the value of these you need to use the tsm configuration get -k command. For example:
Open firewall ports in Windows 10You can manually permit a program to access the internet by opening a firewall port. You will need to know what port it uses and the protocol to make this work.
In 2012 and 2013, I wrote a couple of articles called Scanning Open Ports in Windows: A Quick Guide and Scanning Open Ports in Windows: A Quick Guide (Part 2) that covered how to use a series of neat little utilities to view open ports and troubleshoot client or server side application network connectivity issues. The articles are still relevant today but I also wanted to follow up and discuss using NMAP to check for open ports.
Nmap is a free, open source and multi-platform network security scanner used for network discovery and security auditing. Amongst other things, it allows you to create a network inventory, managing service upgrade schedules, monitor host or service uptime and scan for open ports and services on a host. 2ff7e9595c
