TcpLogView is a simple utility that monitors the opened TCP connections on your system, and adds a new log line every time that a TCP connection is opened or closed. For every log line, the following information is displayed: Even Time, Event Type (Open, Close, Listen), Local Address, Remote Address, Remote Host Name, Local Port, Remote Port, Process ID, Process Name, and the country information of the Remote IP (Requires to download IP to country file separately.)

System Requirements & Limitations

  • This utility works on any version of Windows, starting from Windows 2000 and up to Windows 10. On 64-bit systems, you should use the x64 build of TcpLogView.
  • This utility creates the TCP log by taking a snapshot of currently open TCP connections, and comparing it to the previous snapshot. This means that if a TCP connection is opened for a very short time, then TcpLogView will not be able to capture it.
  • On Windows Vista/7/8 with UAC turned on, you should run TcpLogView as administrator if you want to get full process information.

Versions History

  • Version 1.32:
    • Added support for GeoLite2 City and GeoLite2 Country database in CSV format.
    • In order to use it, extract all files into the folder of TcpLogView.exe
    • Be aware that the loading process of the GeoLite2 City database is quite slow.
  • Versions 1.31:
    • Fixed bug: When exporting the log items while the 'Write To Log File' option was active, TcpLogView started to write the csv log file in Unicode, causing the file to be corrupted.
  • Versions 1.30:
    • The 'Remote Host Name' is now also displayed for IPv6 addresses.
  • Versions 1.27:
    • When the log file is created in the first time ('Write To Log File' option), TcpLogView now adds header line to the file.
  • Versions 1.26:
    • Added 'Save All Items'.
  • Versions 1.25:
    • TcpLogView now displays the process names (Some of them without the full path) for most processes when you run it without elevation ('Run As Administrator'). Also, the 32-bit version of TcpLogView now detects 64-bit processes properly.
  • Versions 1.20:
    • Added 'Run As Administrator' option (Ctrl+F11), which allows you to easily run TcpLogView as administrator on Windows Vista/7/8/2008. It's needed in order to view the information of other processes running as admin.
  • Versions 1.16:
    • Added 'Start As Hidden' option. (This option is available when the tray icon is enabled)

  • Versions 1.06:
    • Fixed bug: The 'Resolve IP Addresses' feature failed to work on some versions of Windows. (Ooops... I forgot to initialize the Winsock DLL...)
  • Versions 1.05:
    • Added 'Scroll Down On New Line' option. If it's turned on, TcpLogView automatically scrolls to the bottom when a new line is added.
  • Versions 1.00 - First release.

Start Using TcpLogView

TcpLogView doesn't require any installation process or additional dll files. In order to start using it, simply run the executable file - TcpLogView.exe
After running TcpLogView, it starts logging the TCP connections, and adds a new line every time that TCP connection is opened or closed. You can clear the current log by using the Clear Log option (Ctrl+X)

Download IP to country file

In order to get country information of the remote IP address ('Remote IP Country' column), you should download one of the following files, and put the file in the same folder of TcpLogView.exe:
    You should save the file as IpToCountry.csv in the same folder of TcpLogView.exe
  • GeoLite2 City database:
    You should download the GeoLite2 City database in CSV format because TcpLogView can only read this file format. In order to starting using this database, simply extract all files in the folder of TcpLogView.exe

Integration with IPNetInfo utility

If you want to get more information about the remote IP address displayed in TcpLogView utility, you can use the Integration with IPNetInfo utility in order to easily view the IP address information loaded directly from WHOIS servers:
  1. Download and run the latest version of IPNetInfo utility.
  2. Select the desired connections, and then choose "IPNetInfo - Remote Address" from the File menu (or simply click Ctrl+I).
  3. IPNetInfo will retrieve the information about remote IP addresses of the selected items.

Translating TcpLogView to other languages

In order to translate TcpLogView to other language, follow the instructions below:
  1. Run TcpLogView with /savelangfile parameter:
    TcpLogView.exe /savelangfile
    A file named TcpLogView_lng.ini will be created in the folder of TcpLogView 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 TcpLogView, and all translated strings will be loaded from the language file.
    If you want to run TcpLogView without the translation, simply rename the language file, or move it to another folder.
