As I was wondering how I could do to relieve my wrt54gl from the huge weight of libopenssl and nsupdate, I thought.. Wouldn’t it be cool if I could set a very restricted account on my server, and just ask my wrt54gl to ssh to it and execute locally nsupdate. So I started searching for a way to restrict user ssh accounts by listing a set a allowed commands. No luck there.
So.. python came to the rescue.
Limited Shell (lshell) is an application that lets you restrict the environment of any SSH user. It provides an easily configurable shell: just choose a list of allowed commands for every limited account. No installation is required.
You can download the current version of lshell from the following link: http://sourceforge.net/project/showfiles.php?group_id=215792
If you want to contribute to this project, please do not hesitate.
Send me a patch, or just your new lshell.py so I can check it out.
You can use the interface on sourceforge.net:

Hello again,
My first objective was to update my DNS from my home. The problem was:
1- I wanted it to be secure (at least the most secure possible)
2- my PC is behind a beautiful WRT54GL which leaves me with nothing but my LAN IP.
I had to install the stuff on my linksys running Kamikaze0.9 of OpenWRT.
After some research and some small space headaches (WRT54GL), here is what I did:

As a small reminder for myself, I post the thread about pyExcelerator.
pyExcelerator is a nice little python module that let’s you write Excel files (not openOffice spreadsheet, the other kind..).
For Ubuntu users, it is very easy to install: sudo apt-get install python-excelerator
Here basic script to write in ‘Hello World!’ excel file:
#!/usr/bin/env python
import os
from pyExcelerator import *
curpath = os.path.dirname(__file__)
workbook = Workbook()
worksheet = workbook.add_sheet('My colour Sheet')
worksheet.write(0,0, 'Hello World!')
workbook.save(os.path.join(curpath, 'test.xls'))

Voici un article clairvoyant notant la différence entre la fierté et l’orgueil d’un développeur qui publie son travail en opensource.. ou pas.

I wanted to setup some VMs using kvm (i had the same problem using xen). The solution a chose to connect my VMs to the internet was to do it through bridging.
My only problem is that my eth0 (main and only ethernet card is connected straight to the Internet. So bridging loses its meaning because I could not choose new IP addresses for my virtual boxes.
The solution: creating a dummy network interface!
With this scenario, i’ll have all my dumUs bridged to the dummy interface (dummy0) and the bridge (br0) NATed through eth0. I hope I’m clear enough. : )
Here is how my /etc/network/interfaces file looks like:

Here is a second howto about the PSP handler of mod_python.
Hope this is useful!

After a bit of research and some debugging time, and as i couldn’t find obvious mod_python howtos, I decided to write a little Apache2/mod_python.publisher howto.

I have searched a lot before finding this tip, so I post it.
It show how to easily import with mod_python a module based on a personal .py file located somewhere on your box.
In this example, I will try to import the module bloup.py located in the same directory of my index.py mainpage.
when trying to import using the usual means, i get:
#!/usr/bin/env python
import os
import bloup
...
>>>ImportError: No module named bloup
The solution I found was:

This time I needed this time to provision the NextGen SQL database with all the folders I’ve put on my server.
Again, i did a little python script. I scans your NextGen gallery folder, and enters all new folders as “galleries” in the SQL DB, and creates the thumbs for the pictures.
This was usefull for me. : )
