intinfo

Portable (between *nixes) information about network interfaces

Description

There is no good cross-platform way to get interface info in python. This doesn't solve that problem, but it at least allows for cross-*nix distro access to this data.

Values for SIOCGIFADDR,SIOCGIFNETMASK, and SIOCGIFBRDADDR were different between my Linux and OSX boxes. I don't know if there are differences beyond that.

Implemented here is a simple Cython module that sucks in these magic values from the apropriate headers and makes them accessible to Python.

Usage

import intinfo
print intinfo.get_ip('eth1')
print intinfo.get_mask('eth1')
print intinfo.get_broadcast('eth1')

Intstallation

You should be able to just:

sudo pip install intinfo

or if you want to build it yourself:

sudo python ./setup.py install

Rebuilding Cython Portion

To simplify distribution, the setup.py file builds from the ioctl_requests.c rather than ioctl_requests.pyx. To re-build the cython module, you could run

cython ./ioctl_requests.pyx

or you could write a new setup.py like this:

from distutils.core import setup
from distutils.extension import Extension
from Cython.Distutils import build_ext

ext_modules = [Extension("ioctl_requests", ["ioctl_requests.pyx"])]

setup(
  name = 'ioctl_requests',
  cmdclass = {'build_ext': build_ext},
  ext_modules = ext_modules
)
