LiveTcpUdpWatch v1.41

A free tool for Windows that displays live information about all TCP and UDP activity on your system.

Every line in the main table of LiveTcpUdpWatch displays the protocol (TCP/UDP/IPv4/IPv6), local/remote IP address, local/remote port, number of sent/received bytes, number of sent/received packets, connect/disconnect time (For TCP only), and the process (ID and path) responsible for this activity.

LiveTcpUdpWatch vs CurrPorts vs NetworkTrafficView
This tool may look very similar to other tools of NirSoft - CurrPorts and NetworkTrafficView, but every tool behave differently and uses different technique to extract the network information.

  • CurrPorts displays the current table of active TCP connections and TCP/UDP listening ports. but this technique has some disadvantages, for example, if UDP packets are sent from your computer to remote network address, you won't see it with CurrPorts, because with UDP there is no really a connection and the UDP table contains only listening UDP ports. The advantage of CurrPorts is the ability to use it without elevation (Run As Administrator).
  • NetworkTrafficView uses network sniffing technique - It analyzes every packet sent/received by your network card and displays extensive summary according to the display mode you choose. The disadvantages of this tool: You have to choose a network card and capture method for activating the network sniffer.
  • LiveTcpUdpWatch uses event tracing API to get live information from Windows Kernel about every TCP/UDP packet sent/received on your system. As opposed to CurrPorts, it captures all UDP activity with process information, but without the need of using a network sniffer.

System Requirements
This tool works on any version of Windows, starting from Windows XP and up to Windows 11. Both 32-bit and 64-bit versions of Windows are supported. On Windows Vista and later this tool requires to run as Administrator (elevation).

Changes
Version 1.41:
Fixed high CPU usage issue when capturing the network activity from command-line (/CaptureTime command)

Start Using LiveTcpUdpWatch
LiveTcpUdpWatch doesn't require any installation process or additional DLL files. In order to start using it, simply run the executable file - LiveTcpUdpWatch.exe

After running LiveTcpUdpWatch, it immediately starts display any TCP/UDP activity on your system. You can choose from the Options menu which protocols you want to capture (TCP, UDP, IPv4, IPv6). You can also press Ctrl+X (Clear All) to clear all accumulated data and start again with empty table. If you want to temporary stop the network tracing , simply uncheck the 'Capture Network Data' option or press F2.

If you want to see only the active TCP connections, simply turn on the 'Remove Closed TCP Connections' option (Under the Options menu).

Merge if only local port is different
If you want to decrease the number of lines displayed by LiveTcpUdpWatch, you can activate the following options: 'Merge TCP if only local port is different', 'Merge UDP if only local port is different' (Under the Options menu).
For example: If your Web browser creates 5 TCP connections to the same IP address and the same port (80 or 443) - instead of 5 lines, you'll get the summary of all 5 connections in one line and the 'Connections Count' column will display '5'.

For UDP, it's even more significant, because every DNS query is sent to the same remote address and port (53), but different local port, so activating the 'Merge UDP' option will put all DNS activity in one line instead of many lines.

IP Address Country/City Information
LiveTcpUdpWatch allows you to view country/city information for the remote IP address. The country/city information is displayed under the 'Remote IP Country' column. In order to activate this feature, you have to download one of the following external files, and put the file in the same folder of LiveTcpUdpWatch.exe:

  • Download the IPv4 CSV file, extract it from the zip/gz file, and put it in the same folder of LiveTcpUdpWatch.exe as IpToCountry.csv
  • You should download the GeoLite2 City or Country database (registration required) in CSV format because LiveTcpUdpWatch can only read this file format. In order to starting using this database, simply extract all files in the folder of LiveTcpUdpWatch.exe

Integration with IPNetInfo utility
If you want to get more information about the remote IP address displayed in LiveTcpUdpWatch utility, you can use the integration with IPNetInfo utility in order to easily view the IP address information loaded directly from WHOIS servers:

Download and run the latest version of IPNetInfo utility and put ipnetinfo.exe in the same folder of LiveTcpUdpWatch.exe .
Select the desired items, and then choose "Check Remote Address With IPNetInfo" from the File menu or from the right-click context menu.
IPNetInfo will retrieve the information about remote IP addresses of the selected items.

Command-Line Options
/CaptureTime <Milliseconds> Specifies the capture time in milliseconds for the save command-line options (/stext, /stab, /scomma, and so on...)
The default is 10000 milliseconds (10 seconds).

For example, if you want to capture the TCP/UDP activity for 20 seconds and then save the result to csv file:
LiveTcpUdpWatch.exe /CaptureTime 20000 /scomma "c:\temp\tcpudp.csv"
/cfg <Filename> Start LiveTcpUdpWatch with the specified configuration file. For example:
LiveTcpUdpWatch.exe /cfg "c:\config\ltuw.cfg"
LiveTcpUdpWatch.exe /cfg "%AppData%\LiveTcpUdpWatch.cfg"
/stext <Filename> Save the report of LiveTcpUdpWatch into a simple text file.
/stab <Filename> Save the report of LiveTcpUdpWatch into a tab-delimited text file.
/scomma <Filename> Save the report of LiveTcpUdpWatch into a comma-delimited text file (csv).
/shtml <Filename> Save the report of LiveTcpUdpWatch into HTML file (Horizontal).
/sverhtml <Filename> Save the report of LiveTcpUdpWatch into HTML file (Vertical).
/sxml <Filename> Save the report of LiveTcpUdpWatch into XML file.
/sjson <Filename> Save the report of LiveTcpUdpWatch into JSON file.
/sort <column> This command-line option can be used with other save options for sorting by the desired column. The <column> parameter can specify the column index (0 for the first column, 1 for the second column, and so on) or the name of the column, like "Local Address" and "Remote Address". You can specify the '~' prefix character (e.g: "~Received Bytes") if you want to sort in descending order. You can put multiple /sort in the command-line if you want to sort by multiple columns.

Translating LiveTcpUdpWatch to other languages
In order to translate LiveTcpUdpWatch to other language, follow the instructions below:

1) Run LiveTcpUdpWatch with /savelangfile parameter:
LiveTcpUdpWatch.exe /savelangfile
A file named LiveTcpUdpWatch_lng.ini will be created in the folder of LiveTcpUdpWatch utility.
2) Open the created language file in Notepad or in any other text editor.
3) Translate all string entries to the desired language. Optionally, you can also add your name and/or a link to your Web site. (TranslatorName and TranslatorURL values) If you add this information, it'll be used in the 'About' window.
4) After you finish the translation, Run LiveTcpUdpWatch, and all translated strings will be loaded from the language file.
If you want to run LiveTcpUdpWatch without the translation, simply rename the language file, or move it to another folder.
