OSX10.10.2 atcd can not work with error NotImplementedError: darwin backend is not implemented!

[boxerxing]

I download and install ATC according to the readme file block in step run atcd with following issue：Traceback (most recent call last):
File "/usr/local/bin/atcd", line 13, in
runner.run()
File "/usr/local/lib/python2.7/site-packages/atcd/scripts/runner.py", line 34, in run

File "/usr/local/lib/python2.7/site-packages/atcd/scripts/runner.py", line 27, in initialize_thrift

'{0} backend is not implemented!'.format(os_name.lower())
NotImplementedError: darwin backend is not implemented!

I use two ways install thrift but always got the same error above.
brew install thrift and git clone source code
hope you give me some advance.

Hi @boxerxing
thank you for reporting this. Unfortunately, we only support Linux for now.

The darwin backend could be implemented, but this is not yet on the roadmap. If you want to give it a try, PRs are welcome :) .
I believe pf can provide the same functionality on MacOSX/BSD, but I have not really given it a look.

Also, mind that ATC must run on a gateway, so to be able to have ATC to shape you traffic, it should be routing the traffic of the devices you want to shape the traffic for.

If you want to fiddle with ATC, you can run it in a VM though as explained in http://facebook.github.io/augmented-traffic-control/docs/contributing.html

This is mainly use for developing on ATC and/or testing, but that can give you a good overview on how it works.

@chantra thank you for your help.I'll try it on ubuntu 13.04 system but Django and MySQL always apt-get failed... I hope use ATC on iPhone between OSX .

@boxerxing
atcd needs to run on a device that routes traffic. To do that, it needs 2 interfaces:

Exception: One of the following interfaces does not exist: eth1, eth0
ERROR:AtcdVService:Unexpected Exception during init

Typically, one of the network interface is connected to your internal network (can be configured with --atcd-lan and defaults to eth1) and one is connected to your uplink to the internet (--atcd-wan and defaults to eth0)
