PortKnocker

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.

no "menu" button on samsung s7e. thus, cannot add hosts...

The Connectbot 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.

This app should be able to be moved to sd card

It's doing exactly what's needed.

Simple and just works! Now I can access my network from my phone and keep the Chinese from endlessly pounding on my router looking proxy servers.

Nice integration with ConnectBot

A one click widget would be nice

Does what it says! Would love to see a few options to specify syn, ack, fin, etc flags. Other than that works great.

Great as far as it goes! I agree with jarek, a more flexible post-knocking app launcher would be excellent (eg for connectbot, mail, etc)

Excellent implementation and integration with ConnectBot is superb. Thanks so much for this.

Does exactly as promised. You would be #1 if you provided a dialog where users can choose what to launch after knocking eg ssh

application looks great, but... to make it really useful for much more people, there should be 2 features added: password protection - many people don't wanna keep list of their routers' ip paired with ports stored anywhere without encryption. simple password on launching app would be awesome. and most important feature for me - strings. many people (incl me) are using layer 7 packet inspection to look for specific strings in form of udp packets. if you could add this feature (so apart of setting up port and protocol - e.g. 1337 udp, add another field for content of the packet - just normal string, your app will be definitely 'must have'.

Access to Media and call info? Why does a simple port-knocking tool need those?
