LiveTcpUdpWatch v1.36 Copyright (c) 2018 - 2021 Nir Sofer Web site: https://www.nirsoft.net Description =========== LiveTcpUdpWatch is a 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 10. Both 32-bit and 64-bit versions of Windows are supported. On Windows Vista and later this tool requires to run as Administrator (elevation). Versions History ================ * Version 1.36: o Added GB and GiB to the 'Bytes Counter Unit' option. o Added option to change the sorting column from the menu (View -> Sort By). Like the column header click sorting, if you click again the same sorting menu item, it'll switch between ascending and descending order. Also, if you hold down the shift key while choosing the sort menu item, you'll get a secondary sorting. * Version 1.35: o Updated to work properly in high DPI mode * Version 1.34: o Added 'Start As Hidden' option. When this option and 'Put Icon On Tray' option are turned on, the main window of LiveTcpUdpWatch will be invisible on start. * Version 1.33: o Added 'Copy Clicked Cell' option to the right-click context menu, which copies to the clipboard the text of cell that you right-clicked with the mouse. * Version 1.32: o The tooltip of the tray icon now shows the number of items displayed on the main window. * Version 1.31: o Fixed the /cfg command-line option to load the .cfg file from the current directory if full path is not specified. * Version 1.30: o Added 'Remote IP Country' column. In order to get IP country information in this column, you have to download one of the following databases and put the files in the same folder of LiveTcpUdpWatch.exe: http://software77.net/geo-ip/ or GeoLite2 database (Only the CSV database is supported) o Added option to check the remote IP address with the IPNetInfo tool. In order to use this feature, you have to put ipnetinfo.exe in the same folder of LiveTcpUdpWatch.exe, select the items with the IP addresses you want to check, and then choose the 'Check Remote Address With IPNetInfo' option from the File menu or from the context menu. * Version 1.26: o Added 'Select All' and 'Deselect All' to the 'Column Settings' window. * Version 1.25: o Added thousands separator to all byte counter units. o You can set any variable appears saved in the .cfg file from command-line. For example, this command set the speed unit to kB/Sec : LiveTcpUdpWatch.exe /SpeedUnit 1 o Added 'Align Numeric Columns To Right' option (It's turned on by default). * Version 1.20: o Added option to filter by process name (In 'Advanced Options' window - F9). * Version 1.16: o Added 'Put Icon On Tray' option. * Version 1.15: o Added option to capture only the specified TCP/UDP ports (In 'Advanced Options' window - F9). * Version 1.13: o Added 'Save File Encoding' option. * Version 1.12: o Added 'Sort On Every Update' option. * Version 1.11: o Added 'Add Header Line To CSV/Tab-Delimited File' option (Turned on by default). o Added 'Always On Top' option. * Version 1.10: o Added command-line options to save the report of LiveTcpUdpWatch into a file without displaying any user interface. * Version 1.07: o Added 'Save All Items' option (Shift+Ctrl+S). * Version 1.06: o Added option to choose another font (name and size) to display in the main window. * Version 1.05: o Added new option: 'Exclude Localhost Addresses'; o Added new option: 'Automatically Scroll Down On New Items' * Version 1.00 - First release. 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: * http://software77.net/geo-ip/: 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 * GeoLite2 City database: You should download the GeoLite2 City or Country database in CSV format because LiveTcpUdpWatch can only read this file format. In order to starting using this database, simply extract all files in the fo
