tcproute/tcptraceroute — the utility is similar to tracert/traceroute, but uses the TCP protocol instead of ICMP or UDP protocols.

Windows

Prepare

Use

If the error "Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'PcapDotNet.Core.dll' or one of its dependencies. The specified module could not be found. at tcproute.Program.Main(String[] args)" occurs when executing the command, the solution may be to install the 32-bit (x86) version of Microsoft Visual C++ 2010 Redistributable Package.
  1. Open command prompt and navigate to the directory where the tcproute archive was extracted. To open the command prompt immediately in the desired directory, open the directory in Explorer, type cmd in its address bar and press Enter:
  2. Execute the command (instead of 80 specify the desired port, instead of example.com — the address of the desired site without http:// or https:// at the beginning and / at the end):
    tcproute -p 80 example.com

  3. The program will display a list of available network interfaces and ask you to specify the number of the one you want to use. Interface names and numbers may vary from device to device. Enter the desired interface number and press Enter.
