TCPView for Windows, Tool to check TCP and UDP Connections on your system

Posted by Daniel - 3,159 Views

tcpview_small.jpgIt was a suggestion from a good friend of mine who told me to try TCPView when I asked him about a tool to check SQLServer Connection instances created by my program.

All I need is to check whether my program is not forgetting to free any DB connection instances when it is terminated and this TCPView for windows give me what I need.

Using TCPView

When you start TCPView it will enumerate all active TCP and UDP endpoints, resolving all IP addresses to their domain name versions. You can use a toolbar button or menu item to toggle the display of resolved names. On Windows NT, 2000 and XP systems TCPView shows the name of the process that owns each endpoint.

By default, TCPView updates every second, but you can use the View|Update Speed menu item to change the rate. Endpoints that change state from one update to the next are highlighted in yellow; those that are deleted are shown in red, and new endpoints are shown in green.

You can close established TCP/IP connections (those labeled with a state of ESTABLISHED) by selecting File|Close Connections, or by right-clicking on a connection and choosing Close Connections from the resulting context menu.

If you want to see who owns the domain registered for a remote address, select the item containing the name and choose Whois from the context menu or the File menu. You can save TCPView’s output window to a file using the Save menu item.
