PortKnock

Veröffentlicht von: Danny Sung

Beschreibung

-- Overview --
This application is a simple port knocker for the iPhone, generally useful only to network administrators. You *must* have a port knock daemon running on your server for this application to be useful.
Features in this version of Port Knock:
- Password Protection
- Knock Validation
- Import/Export Hosts
- Auto App Launcher(+)
- Knock Progress Screen
- Shows your External IP Address
- Arbitrary number of ports per host
- An unlimited number of host definitions
- TCP/UDP configuration per port
- Selectively sending knocks through WiFi or Carrier/3G networks
- Configurable interpacket delay
- Has no advertising
-- Use Cases --
This app is ideal if you're on a WiFi network but don't have a port knocker on the available computers. If you're sitting behind a NAT, the iPhone/iPod Touch will have the same IP as any of the other computers on your network.
This is also great to use with TouchTerm or any other ssh or telnet software for the iPhone.Just give it the hostname and a list of ports, and whether you want it to send TCP or UDP packets.
-- Brief Description of Port Knocking for the Layman --
Port Knocking is a technique to secure services behind a firewall until a specific knock sequence is given. This is not to be confused with port scanning (a network management tool for discovering open services on a system).
Imagine you left your kids at home alone. You don't want them to open the door for strangers. And when a stranger comes knocking, you don't even want them to come to the door, because you don't want them to know your kids are there. But, when you or other family members come, you might want them to open the door for you. So you teach them to listen for a certain rattat-tat-tat or special knock that only you and your family know.
This is the same concept you can apply to your servers. If you run a knock daemon on your server, this app then lets you send the special knock to it.
A more technical description of port knocking can be found on Wikipedia:

-- Additional Info --
If you're in need of a knock server, I personally use Judd Vinet's knock daemon for linux. It's quite easy to use: http://www.zeroflux.org/projects/knock

-- Notes --
+ There are some restrictions regarding the Auto App Launcher. For SSH, you can only create temporary connections. For Mail, you will always be shown a new compose mail window first. Unfortunately, this is due to the way App integration works on iOS. There's not much I can do to address these issues at this time.

Works well

Having used the app for several weeks and on several servers I am very happy. I never have to repeat the knock sequence and haven't found any bugs.

Doesn't work on my iPhone 4 w/iOS 4.2.1

I have port knocking set up at home and I was looking forward to being able to knock from my iPhone. I downloaded this app (PortKnock v2.01) and it will not allow me to enter a host to knock. When I try to enter a host, the field will flash blue but no keyboard ever comes up for me to enter data. My assumption is that this app needs an update in order to work with iOS 4.2.1. Until that time it's useless with an iPhone 4 running the latest version of iOS (4.2.1 as of this writing).

Works, but could be better

Works as advertised, but I would like to have the ability to copy hosts. It takes to many taps to enter port sequences.

Works as expected

Quite a handy app for triggering port knock actions on my server. Simple and easy to use.
