Comments on PortKnocker for Android

★★★★★ unknownDaemon · Jan 29, 2010
It is a very usability and useful tool. Support mixed are TCP and UDP ports knocking. Also, can up a Connect Bot if it changes in settings. +1024! ;)
★★★★★ A Google User · Aug 23, 2011
Bish, bash, bosh The Connect bot integration is great. When I got this phone, I wasn't sure whether I could get port knocking and tunneled cifs/nfs working, let alone achieve the whole process in a single click. Great little utility, thanks.
★★★★★ A Google User · May 25, 2012
Great app Works like a charm. Connect Bot integration is great.
★★★★★ A Google User · Sep 6, 2013
Perfect Does exactly what it says and quickly. Connect bot integration is simple and flawless.
★☆☆☆☆ A Google User · Feb 10, 2015
Why does it need those perms Access to Media and call info? Why does a simple port-knocking tool need those?
★☆☆☆☆ A Google user · Aug 13, 2019
No "menu" button on samsung s7e. Thus, cannot add hosts...

Description by Stephen Paine Written by the developer, not by AppBrain. Click to read.
This application allows people (who are running a port knock daemon) to send TCP or UDP packets to the specified ports. Based off the other app PortKnocking, but faster.

Not a hacking app.
