TCP Monitor

© 2005-2012 Igor Tolmachev, IT Samples

TCP Monitor is a Windows program that will show you detailed listings of all TCP endpoints on your system, including names of remote servers and state of TCP connections.

Under Windows XP and newer TCP Monitor allows you to display all network processes and kill them if needed. Additionally, you can use the "BlackList" option for controlling any TCP endpoints.

TCP Monitors allow you to adjust the list refresh rate and table colors. Additionally, you can kill any running process or its tree from the context menu.

TCP Monitor When you start, TCP Monitor will enumerate all active TCP 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.
