Perfect Does exactly what it says and quickly. Connectbot integration is simple and flawless.

by A Google User the 4/18/2013

looks great, but... 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'.

Great app Works like a charm. ConnectBot integration is great.

Bish, bash, bosh 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.

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

by A Google User the 2/18/2011

A one click widget would be nice

by A Google User the 2/13/2011

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

by A Google User the 2/10/2011

Not a thing to complain about! You get exactly what you ask for...

by A Google User the 5/22/2010

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)
