The best way to check if a port is blocked is to do a port scan from the client machine. What I mean by this is that NETSTAT may show that the 0.0.0.0 is LISTENING on port 3306 but a firewall may still be blocking that port which is preventing outside connections so it isn't sufficient to rely on NETSTAT alone. NETSTAT will tell you if the port is listening but it will not tell you if the port is open to the outside world. If you do not see that, you need to work with your application (MySQL) to get that started first. You should therefore see a listener for 3306 accepting incoming connections.

So, I presume you are running MySQL server on this windows machine. If this is not seen, you have probably missed adding an exception with the firewall to allow this app/service.įinally, port 3306 is typically used for MySQL. If you are running an application/service that is listening on 3306, the firewall config should show it to be Enabled. If you have an active block (incoming connections are being dropped by firewall) after you start logging, you should see that in the log. This command will dump the Windows firewall configuration detail

this will list the blocked ports as well as active listening ports with application associations.

(Updated for Windows 7 users - as referred by Nick below - use netsh advfirewall firewall)

There is one more command to check the firewall state

If this is seen, you will want to add an exception for this port.

Now, when the connection attempt is made (assuming you know when this is done), look at the log file for a drop on port 3306.

Look at the log file location (if not present, define one).

Click on the Settings button next to "Local Area Connection".

Go to Windows Firewall, Advanced settings.

This will confirm there is something running on the port.Īfter this, if you are expecting incoming connections on this port and feel that the firewall may be blocking them, you could use start windows firewall logging and check the logs for dropped connections This can be avoided by upgrading to a version of the app that is signed by its developer.Since you are on a Windows machine, these things can be done:Įxecute the following command and look for a ":3306" listener (you did not mention UDP/TCP).

Instead, it the "Allow or Deny" dialog appears every time the app is opened. If the firewall recognizes such an app it doesn't sign it.

Some apps check their own integrity when they are opened without using code signing. If you want to deny a digitally signed application, you should first add it to the list and then explicitly deny it.

If you choose Deny, OS X adds it to the list but denies incoming connections intended for this app. If you choose Allow, OS X signs the application and automatically adds it to the firewall list. If you run an unsigned app that is not listed in the firewall list, a dialog appears with options to Allow or Deny connections for the app. Apps included in OS X are signed by Apple and are allowed to receive incoming connections when this setting is enabled. For example, since iTunes is already signed by Apple, it is automatically allowed to receive incoming connections through the firewall. Applications that are signed by a valid certificate authority are automatically added to the list of allowed apps, rather than prompting the user to authorize them.
