CurrPorts

Test what TCP and UDP ports are open on your computer.

Nearly everyone knows the TCP and UPD ports, because they are the ones that are used by P2P clients, and for them to work it is necessary to open them. But they don't only serve to download things, any application that connects to Internet uses a TCP or UDP port, or both of them. To know what ports are being used you can resort to CurrPorts.

  By only launching CurrPorts, we will be able to know the specific name of a process, the processes number, protocol, port number, name of the local port, state.... a lot more data. What's more, CurrPorts allows to configure the filtering of specific ports, view the ones that are listening, established, closed,... it is possible to obtain the data of nearly anything and export them to different formats, including TXT, HTML and XML.

  Thanks to CurrPorts it will be possible to monitor any of our computers ports to know what or who is using it, something very interesting for net administrators or for any user that wants to be sure and informed of everything that connects to the net from your PC.

  Requirements: Windows NT/2000/XP/2003/Vista/7. To use this application in Windows NT it is necessary to install psapi.dll in the \Windows\System32\ folder. This download requires a ZIP compatible compressor.
