How To Run Tracetcp In Windows and Linux

TraceTcp is mostly used by end users to test the TCP port connectivity. They do Tracetcp from windows command line, Tracetcp uses TCP SYN packets rather than ICMP/UDP packets that the usual implementations use, thus bypassing gateways that block traditional traceroute packets tracetcp.

To run Tracetcp in windows, two components are required- Wincap and Tracetcp.exe.

Wincap  allows applications to capture and transmit network packets bypassing the protocol stack, and Tracetcp is a application which runs TCP syn packets from the source machine.

Download Tracetcp and Wincap

1. Download Wincap and install.
2. Download Tracetcp.exe

Linux and OSX

tcptraceroute is included by default in most Unix based distributions. On OSX you will need to install it via homebrew (http://brew.sh/) by running the following command

brew install tcptraceroute

Command syntax:

tcptraceroute hostname port

Example:

sudo tcptraceroute api.opendns.com 443

NOTE:  On some operating systems like OS X you may need to run tcptraceroute as root.  We’ve included ‘sudo’ in the example commands below to do that.

admin-0369:Tools admin$ sudo tcptraceroute api.opendns.com 443
