Ping over TCP

ping can't do TCP ping so in order to run ping for TCP we can use tcpping.

Installation

Firstly we have to make sure tcptraceroute is installed by running -

$ apt-get install -y tcptraceroute

Then to install tcpping, run -

$ wget http://www.vdberg.org/~richard/tcpping -O /usr/bin/tcping
$ chmod 755 /usr/bin/tcping

Note: I am saving tcpping as tcping here

Example

jungle@DESKTOP-B73I3A0:~$ tcping -x 5 google.com
