The remote address will be listed as "*.*" since the UDP protocol does not support connections. For example, if a program opens UDP port 3200 and specifies local IP address 0.0.0.0, you will see a line in the static view with the name of the process, UDP as the protocol, and "0.0.0.0:3200" as the local address. The static view shows you a snapshot of the existing TCP/IP endpoints on the system. You can use the tab key to move between views.

Dynamic View - shows real-time TCP/IP activity.

Static View - shows a snapshot of endpoints active on the system.

When you launch the GUI tool you are presented with two sub-windows: In order to listen it must define connection endpoints that it can, and if it wishes to establish a connection when a connection request arrives it accepts the connection with another TCP endpoint. When a process waits for a connection, it listens for incoming connection requests. An attempt to connect with a remote endpoint is called a connect request, and the process specifies the remote endpoint's address/port-pair. For example, a web server uses port 80 because that port number is defined as being the http port, and internet browsers by default attempt connections to that port number.Īfter assigning an address/port-pair the process can either initiate a connection to a remote endpoint or wait for incoming connections. A process typically specifies a port number if it provides a service that has a defined port number associated with it. 209.233.4.14)Ī process can either explicitly specify a port number or let the TCP/IP stack assign one for it.

or as an IP address assigned to the computer (e.g.

Local IP addresses can be specified in three different ways: The IP address of course must be one local to the computer. A TCP session is initiated by a process allocating a TCP endpoint (object) and assigning it an IP address and port number. TCP offers connect-oriented, reliable communications. This section provides a brief (and simplified) description of TCP and UDP. TCP/IP actually consists of three protocols: TCP (Transmission Control Protocol), UDP (Unreliable Datagram Protocol) and IP (Internet Protocol). Filter the data captured so that you only see accesses performed by a specific process, or that involve particular local or remote addresses.Save TCP/IP activity logs and connection information to file.Watch an application's TCP/IP activity in real-time.Obtain detailed statistics on the amount of data sent and received over a connection.See what remote network addresses suspicious applications are accessing.Determine which process has an address opened.TCPView Professional’s capabilities let you:

Finally, TCPView Professional offers a range of configuration options that let you auto-refresh its display, save output to a file, and filter and highlight entries by process, IP address, or port. TCPView Professional also lets you see the amount of data sent and received over a network connection, which makes it a useful tool for performance diagnostics. These features make TCPView Professional a uniquely powerful tool for networking and application troubleshooting. TCPView Professional also lets you see TCP/IP activity by process in real-time, a feature not available with any other utility.

Unlike builtin TCP/IP monitoring tools that come with Windows (such as netstat), TCPView Professional shows you which process is associated with each TCP/IP address, making it easy to determine what application is responsible for specific connections and activity. TCPView Professional allows you to monitor TCP/IP network activity on Windows NT 4.0, Windows 2000, Windows XP, Windows Server 2003, and Windows 9x systems.
