Interfacing with Linux’s wireless tools from Python is, plainly put, awful. All
existing solutions I’ve come across either parse the output of command line
tools, or use a mixture of
array.array() objects and the
module to get what you want. Not exactly maintainable or sane.
There was one Python module I can across, called
python-iwlib, developed by
some Redhat/Fedora folks to provide the output of iwconfig in a much more
programmatic way, using the C API to retrieve the information. It had been
orphaned since 2012, so I’ve taken ownership in the hopes of bringing it more
up to speed.
What does it give you, now? Here’s a short list:
- Access point scanning.
- Setting the essid of a device.
- Check if an interface supports scanning.
That’s just a start - the
wireless_tools package is huge, but my eventual
plan is to provide a native interface for the complete toolset, all in Python,
with no need to use the things I mentioned earlier.
If you find a feature missing, then submit a feature request. If the
wireless_tools package can do it,
python-iwlib can. I’m more than happy to
implement things as people require them, and that’s probably the only way it’s
going to get many of the features that I won’t use, because I’m not
implementing the entire thing for nothing :)
I’ve tested it in CPython 2.7, and it works as expected. I’d love more people
to use it, to get more of an idea how well it works against different versions
wireless_tools and CPython.
