Enabling SSH on ASUS RT-N56U Router

Categories: Development Notes • Linux; Tagged with: padavan-rt-n56u • RT-N56U • RT-N56U Firmware • SSH; @ May 15th, 2016 15:36

the default firmware doesn’t provide the SSH feature, however, with the help of padavan‘s rt-n56u project, you may enable it:

This project aims to improve the rt-n56u and other supported devices on the software part, allowing power user to take full control over their hardware. This project was created in hope to be useful, but comes without warranty or support. Installing it will probably void your warranty. Contributors of this project are not responsible for what happens next.

How do I get set up?

Get the tools to build the system or Download pre-built system image

Feed the device with the system image file (Follow instructions of updating your current system)

Perform factory reset

Open web browser on http://my.router to configure the services

What I did:

download RT-N56U_3.4.3.9-099_base.trx
login to the router setting dashboard, and upgrade the firmware by selecting the downloaded file.
after couple minutes, my router reset, I connect to the router via cable, and setup wifi. (you may try ‘1234567890’ to connect to your wifi network if you cannot connect to it directly)
login to the router setting dashboard, you’ll find a new UI! navigate to: Advanced Settings > Administration > Services to setup your ssh server. more details: https://bitbucket.org/padavan/rt-n56u/wiki/EN/CommonTips

Python: multiprocessing forking.py assertionError

Categories: Development Notes • Python; Tagged with: Lettuce • Nosetest • Python; @ March 22nd, 2016 23:32

Issue: There’s an AssertionError when I try to test mutliprocessing features using lettuce 0.2.22 / nosetests and python 2.7.10 error details:

multiprocessing\forking.py AssertionError: main
File "", line 1, in 
File "C:\Python27\Lib\multiprocessing\forking.py", line 380, in main
  prepare(preparation_data)
  File "C:\Python27\Lib\multiprocessing\forking.py", line 488, in prepare
    assert main_name not in sys.modules, main_name
AssertionError: __main__

upgrade to python 2.7.11 becuase this is a fixed bug: https://bugs.python.org/issue10128; or
use a wrapper (.py file name should be not in sys.modules, main_name):

# run_at.py:
__requires__ = 'lettuce==0.2.20'
import sys
from pkg_resources import load_entry_point

if __name__ == '__main__':
    sys.exit(
        load_entry_point('lettuce==0.2.20', 'console_scripts', 'lettuce')()
    )
