Port Knocker Android Client

Port Knocker

Description

A basic port knocker client for Android. Similar to the other port knocker apps but with a nicer interface. Also includes a widget and the ability to choose an application to launch after knocking.

Usage

First create a host. You must specify a label, hostname and at least one port. The delay (in ms) is the amount of time it will wait in between sending packets. The default value of 1000ms is recommended to prevent the host from receiving the packets out of sequence. You can optionally choose an app to launch after the knock is complete. Once the host has been created you can initiate the knock sequence by simply clicking on the host. The same thing applies to the widget.

Privacy

This app does not track, collect, or share any data it comes across with anyone or anything. There are no ads or analytics trackers in this software. It does not access, store, nor transmit any user data. Only data entered into the application is stored within the application on this device and is not stored outside of this device.

portknocker's Issues

Spinner menu closes on device rotation

When I perform these sequences of events, the spinner menu on screen disappears:

Sequence 1:

1. Click on Edit host icon
2. Click on Ports
3. Open Protocol spinner
4. Orientation Change

Sequence 2:

1. Click on Edit host icon
2. Click on Other
3. Open Launch application spinner
4. Orientation change

The formation of a package with the contents

You can add to the program the ability to send a package with content (text), for devices that analyze the content of the package is a big plus in security.

(BUG) The program does not send packets

The program tries to connect to the specified ports, If the ports do not respond, then the program does not send packets. My ports do not respond, my ports can not be found to be tapped. Make an option in the settings so that you can just send the packet and do not wait for an answer.

Tasker support plans?

This app is awesome, and I use it all the time now.

Are there any plans to support Tasker in the near future?

Unexpected behaviours after a screen orientation change (reported by activity)

I developed an automatic test case generation tool and it detected these problems in your app.
I would like to know if you consider them as failures and, if not, why. Thanks for your collaboration.

1. When I change the orientation of the device screen, the menu disappears in HostListActivity
   
   

2. When I change the orientation of the device screen, "Paste" option disappears in EditHostActivity
   
   

incompatible API use in your code.

Hi,
Our tool detect this app's apk file from f-droid.org(version: 1.0.11) and find several potential bugs. We already check them but we cannot make 100% sure that they are definitely bugs. So we need your help.

We find component "com.ianhanniballake.localstorage.LocalStorageProvider" in AndroidManifest.xml is actually from an external library. This class extends from DocumentsProvider which is added into SDK since level 19. while your app's minSDKVersion is 10. So this is very likely to cause your app crash.

please help to check. Thanks very much.

Dialog disappearance may reduce user experience

Hi, dear developers!

#General information
my device: android 10

There exist some dialog disappearance after screen rotation. I think that screen rotation shouldn't do damange to the UI state. The re-created UI should be the same as before rotation, Right?

I think it is not hard to save the UI state of these dialogs by saving the return value of dialog.isShowing(). In this way, you can decide whether to re-open these dialogs when the phone rotation and UI recreation occur. This may improve the user experience, do you think so?

Permission denied when knocking a domain address (instead of ip address)

When connected via mobile network I'm not able to issue a port knock to a domain address (e.g. server.domain.com). I'm getting the error message "Permission denied", but port knocking an IP address is no problem.

Any ideas? Do other have the same problem?
