Python – ny python package that could configure IP address of network interface

linuxpython

I am writing a server application which allow remote client to show/add/change/delete IP addresses of network interfaces of the machine where the host is running.

The OS is Linux(CentOS 5.2), so I could do that by simply parse and edit configure file. But is there any package that could simplify the job?

And if there is none such package, if I open source my implementation, will that help other people?

It looks like the open source project confparse should be able to easily do what you're looking for. In fact, one of their examples is parsing and modifying /etc/sysconfig/network-scripts/ifcfg-eth0 with ease.

If you find this isn't what you need, I say that any efforts towards open sourcing software will inevitably help other people at some point, given that it is actually useful. ;)

Python – How to import a module given its name as string

With Python older than 2.7/3.1, that's pretty much how you do it.

For newer versions, see importlib.import_module for Python 2 and Python 3.

You can use exec if you want to as well.

Or using __import__ you can import a list of modules by doing this:

>>> moduleNames = ['sys', 'os', 're', 'unittest'] 
>>> moduleNames
['sys', 'os', 're', 'unittest']
>>> modules = map(__import__, moduleNames)

Python multiprocessing: Permission denied

For POSIX semaphores to work, the users need r/w access to shared memory (/dev/shm).

Check the permissions to /dev/shm. On my laptop (Ubuntu) it looks like this:

$ ls -ld /dev/shm
drwxrwxrwt 2 root root          40 2010-01-05 20:34 shm

To permanently set the correct permissions (even after a reboot), add the following to your /etc/fstab:

none /dev/shm tmpfs rw,nosuid,nodev,noexec 0 0

Haven't tried this, just copied from a forum post.
