Please don't hesitate to contact me if you encounter any bugs, or even if you just have suggestions.
The code is open source and can be found at: https://github.com/xargsgrep/PortKnocker
It supports 3G, protocol recognition, and many other features.
If you don't understand how to use it, just send me an email, I'll explain it more precisely.
This application also comes with a Port Encyclopedia, enabling the user to quickly look up what a certain port's function is. A local database is stored on the phone for defining ports, however there is also an option to look it up online for the most recent information.
For more information, questions, or concerns, leave a comment below or contact me via email.
NOTE: If you like this application and want to support it's developers consider the paid version 'SSH Autotunnel Pro', which is actively developed, supported and opened for new feature requests. Also please report any bugs to my email instead of user reviews so that I can ask for additional details and have the problem fixed.
This application can create secure tunnels using a SSH connection for the user to access services available only from the target machine. For example user can connect to the company server and then use web browser to connect to internal web site of their company, use remote desktop to connect remotely to their office PC desktop and control it from their Android device, or bypass a firewall restriction in their hotel or company by connecting to Internet pages from the remote machine.
The application uses standard SSH protocol, without the need to configure and setup a VPN. The only information the user needs to know is the login information to the remote machine and IP/port information of the service they want to connect to. Once the SSH tunnel has been established, the user can connect to the specified local port to access the network service on the remote side using the same application they normally use when their device is connected to that network. The local port need not have the same port number as the remote port.
SSH Autotunnel is better than connectbot at recovering from network disconnects. It also consumes less power because it does only one thing and does not emulate any terminal.
Ssh Autotunnel is using JSch and Bouncycastle projects, which are under BSD and MIT licenses
You put public address of as a server that is entry point to the intranet. Use username@ip[:port] (you can use hostname instead of ip of course and you can use different port than 22). Then use either password or ssh key (or both in which case ssh key is expected to be encrypted with the given password). Then on the menu you can add forwardings. You can have as much forwarding for one connection as you want. You need to specify local port, host and remote port. You can also select if this is local or remote forwarding. See https://en.wikipedia.org/wiki/Port_forwarding for more details on port forwarding. Also note that this application doesn't support any kind of SOCKS proxy.
The application supports both types of private keys - those generated by putty's keygen (ppk) and also the open ssh keys (Linux format). Just copy/paste the content of the key file to the appropriate text box or enter path to the file location on the Android device (e.g. /sdcard/id_rsa.pub). If you experience connection issues and are sure your password is correct, try reexporting your key using a certified tool (such as puttygen) and use the exported key with SSH Autotunnel since some tools do not generate proper OpenSSH format keys.
Also check with your ssh server administrator about server logs.
Root is required, because you need root to change to a port below 1024.
Note. If you find a bug or have a problem please contact us by email since we cannot help you if you post it in the reviews.
And we haven’t even mentioned all; you can even set a dynamic DNS updater! So you can always access your device from everywhere, even if the IP changed!
It also has extensive logging functionality, and you can even set the app to email you the log automatically!
- Internal port forwarding/mapping (set source and destination port)
- Forward to an internal IP as well
- Start/Stop automatically when connected/disconnected from a specified WIFI network, or on boot
- Verbose log (filter, email, etc)
- Add a Dynamic DNS Updater using the local or public IP of your device
- Add multiple Port Forwarders
- For every Port Forwarder you can set name, enable logging, only log errors, start the server when connected to a specific WIFI network and disconnect when the WIFI network is lost, start on boot, set rules
- For every rule you can set the source and destination port and optionally a destination host. You can also set your custom command to add/remove the rules (using iptables commands).
- Add multiple dynamic DNS updaters (set a custom URL, or choose from ChangeIP, DNSdynamic, DNSexit, DNSMadeEasy, DNS-O-Matic, DNSPark, DtDNS, DynDNS, easyDNS, eNom, HE.net, Joker, Namecheap, No-IP, ZoneEdit)
- For every dynamic DNS updater set the name, timeout (in minutes), hostname, username, password and whether to update with the local or public IP address, start the Dynamic DNS Updater when connected to a specific WIFI network, update on connectivity change, start on boot
- On the settings page of the app you can set the maximum log items to keep, whether to keep a WIFI lock (prevent WIFI from disconnecting automatically), keep the device alive, keep the device alive full (keep the screen on, battery intensive), set to start the app on boot
- You can search/filter the log, or set it to be automatically sent when the log limit is reached.

The Arduino software can be downloaded from the link below:
After the installation of the application and when you connect the Arduino Uno board to your Android device, the system asks for a permission and you must give the permission to the app to use the USB interface. Otherwise it won't work.
Note: Tested on Samsung Galaxy S3 with an Arduino Uno R3 board. Please give feedback about any problems.
Caution: Please use this software at your own risk. Be sure about the electrical connections of the Arduino board to avoid any short circuits.
Keywords: Arduino, Arduino Uno, Port Control, Microcontroller, Digital Control, Touch Interface for Arduino.
- Set timeout for each scan.
- Determine sinle port, range or manually pick ports to be scanned.
- Ability to set amount of threads to use in scan.
Timeout: If you are on slow WiFi or Mobile network, it is recommended to set higher timeout to get some results.
