Note: It's been a long time since I've updated pynetkey. It should still work, but some things below (like the installation instructions) are probably no longer valid. I suggest getting the latest source from https://github.com/janto/pynetkey and trying that. Also if you want to open the firewall from the terminal use the cli.py file.

This program was not written by IT and is not supported by them!
Pynetkey's main goals are to be more robust and attractive (it sits in the system tray) than the existing inetkey/sinetkey. It also runs on both Windows and Linux systems. Pynetkey is released under the GPL.

1. download pynetkey.**zip** from the main site
2. extract somewhere permanent and run pynetkey.exe
3. (optional) create a shortcut to pynetkey.exe (such as on your desktop)

To install the GUI version

1. download pynetkey.**deb** from the main site
2. open it (by for example double clicking) and click on the "Install Package" button
3. a Pynetkey icon wil appear in the Applications menu under Internet. You can right click on it to add an additional launcher icon to the desktop.
4. an entry under sources.list.d will be automatically added

The GUI version was developed with an ubuntu/gnome system in mind. A minimal single-file non-gui version is also available as cli.py and should run on most systems with Python2.6. If you have an earlier Python, installing the SSL package might work. If you installed the GUI version, the non-gui version is accessible from the terminal as python-cli.

Since the code is GPL, feel free to start hacking at it. If you do something interesting let me know and I might integrate it with my version. You can pull the latest code from the main repository with

• git clone [email protected]:janto/pynetkey.git

For this to work you need to be already connected to the internet

You can run build.bat to create a distribution file. You will need:

• at least python2.6
• py2exe
• pywin32

Pynetkey's default behaviour can be modified by creating a config file in the following location (or just select "Edit config file..." from the popup menu):

• On Windows: ~\inetkey.ini (usually C:\Documents and Settings\username\inetkey.ini)
• On Linux: ~/.inetkeyrc

WARNING: Please be aware how dangerous it is to store your username and password on your computer. If you don't know why this is dangerous, I suggest you rather not do it. Someone can easily steal your password. This is also why I won't make this feature easily available from the GUI. IT does not like the idea of people storing their passwords on disk.

Pynetkey will automatically encode the password to prevent wandering eyes from stealing your password, but it is NOT the same as it being encrypted.

You can force an open or close event at scheduled times. This is useful for things like automated downloads / torrenting. The current implementation is accurate to within 30 seconds.

The events in the example config file might also be useful. It will open the firewall 5 minutes before the low cost timeslot and closes it 5 minutes before it ends.

Remember that the amount you get charged depends on the timeslot in which your download finishes. Also, configure your download manager / torrent application to stop in time. Don't trust that your download will stop just because you closed the firewall.

Under the [events] section you need to have entries in the form of close1 = Mon 07:55. The day of week is optional, so open3 = 02:00 will open the firewall each morning at 2 am.

Setting open_on_launch=1 (the default) will open the firewall on pynetkey's launch. Set open_on_launch=0 to disable this feature.

Setting notify_on_error=1 (default) will use pynotify to alert the user when an error occurs. This might become irritating on bad connections (SCN/matieswifi), in which case disable it by setting it equal to 0.

[config]
username = 12345678
password = supersecret
open_on_launch = 1
notify_on_error = 1

[events]

close1 = Mon 07:55
open1 = Mon 23:55

close2 = Tue 07:55
open2 = Tue 23:55

close3 = Wed 07:55
open3 = Wed 23:55

close4 = Thu 07:55
open4 = Thu 23:55

close5 = Fri 07:55
open5 = Fri 23:55

The deb file installs a shortlink to cli.py as /usr/bin/pynetkey-cli. That means you can just type pynetkey-cli into the terminal for quick firewall control.

The pynetkey terminal command will give you some control of a running pynetkey gui process.

If you want a more persistent command line process you might be interested in the following command: screen -d -m pynetkey-cli -c ~/.inetkeyrc This will create a screen session and immediatly detach it. cli.py will continue to log in and stay connected. You will need to attach the screen with screen -r to log out when you're done.
