pytun is a Python module which let you create TUN/TAP device very easily.
License: MIT (see LICENSE)
Install pytun with pip install python-pytun or download this archive, decompress it and execute python setup.py install. As pytun is a C module you will need a compiler (e.g GCC) and the Python developpement headers installed on your system (e.g on Debian-like distribution check that build-essential and python-dev are present). There are no dependencies other than the Python Standard Library.
NOTE: On most distributions you will need to be root to create TUN/TAP devices.
To create a TUN device:
from pytun import TunTapDevice tun = TunTapDevice()
To create a TAP device:
from pytun import TunTapDevice, IFF_TAP tap = TunTapDevice(flags=IFF_TAP)
To create a TUN/TAP device with a custom name use the name keyword:
tun = TunTapDevice(name='mytun')
You can get/set some parameters of the device directly:
print tun.name tun.addr = '10.8.0.1' tun.dstaddr = '10.8.0.2' tun.netmask = '255.255.255.0' tun.mtu = 1500
If the device is a TAP you can also get/set its MAC address:
tap.hwaddr = '\x00\x11\x22\x33\x44\x55' print tap.hwaddr
To make the device persistent:
To bring up the device:
To bring down the device:
To read/write to the device, use the methods read(size) and write(buf):
buf = tun.read(tun.mtu) tun.write(buf)
To close the device:
You can also use TunTapDevice objects with all functions that expect a fileno() method (e.g select())
