Binding eth device to a MAC address

-
Having multiple network cards can be a little confusing. The device associated with an eth device might got mixed up when you change your kernel. Here is a little guide to overcome this.

1st : Getting the MAC address

run /sbin/ifconfig , copy HWaddr value and figure out which network card it belongs to.

eth0 Link encap:Ethernet HWaddr 00:E0:4C:43:D8:80

2nd : Edit the conf

as root, open /etc/sysconfig/networking/devices/ifcfg-ethN (N is the number of your eth device) using your favourite text editor. Add this key into the configuration:

HWADDR=device-MAC-address
3rd : Restart computer

restart the computer to apply the bind. (if you are very good in kernel modules, you can try to apply the setting without restarting)

Tee'ing Python subprocess.Popen output

-
A little hack for python coders out there who wanted to have a functionality similar to the unix's tee command for redirecting output to multiple places.


import sys
from subprocess import Popen,PIPE
p = Popen(['put','command','and','arguments','here'],stdout=PIPE)

while True:
o = p.stdout.readline()
if o == '' and p.poll() != None: break
# the 'o' variable stores a line from the command's stdout
# do anything u wish with the 'o' variable here
# this loop will break once theres a blank output
# from stdout and the subprocess have ended

Consolidated community site infrastructure on Plone

-
In Inigo, we believe in helping out local FOSS communities and help them grow. We help out in community events where we can, present FOSS talks, and provide some platforms for local communities to grow. One of such platform is our consolidated community site infrastructure on Plone.

The system/infra and its components was originally developed for the Fedora Malaysia website, while keeping in mind to keep it generic enough so that other communities could use the same components for their own community sites. The infra is already at a usable state, and we can add new sites easily with just a few clicks.

Features in this consolidated infra are:
Document/Content management (Plone built-in)Calendar system (powered by solgema.fullcalendar addon)Conference/BarCamp system (powered by collective.conference addon, which was developed for FUDCon Kuala Lumpur 2012)Blog (powered by Products.Scrawl)Simple yet powerful theming engine (powered by plone.app.theming/ Diazo) - Check out Diazo, you'l…

HOWTO: Linux Container (LXC) on Fedora 12

-
Image
Those who are familiar with BSD Jails or Solaris Zones might be quite familiar to the concept of OS-level virtualization. The Linux world have several options for this, such as the User Mode Linux (UML), OpenVZ, Linux Vserver, and most recently, Linux Container (LXC).

Unlike the other alternatives, which requires specially patched kernels to run it, LXC got fully functional in the upstream kernel since 2.6.29, which is a plus as it made it easier to deploy it in many prexisting distros which ship 2.6.29, including Fedora - without messing around with the distro packages.

In this HOWTO, I'll guide through the process of deploying your own LXC in Fedora 12, with NAT to libvirt's virbr0

Preparation

yum install libvirt lxc

(ping me if i forgot to add any packages)

start libvirt so that virbr0 is configured
/sbin/service libvirtd start

mount control group in /cgroup
echo "none /cgroup cgroup defaults 0 0" >> /etc/fstab
mkdir /cgroup
mount /cgroup

LXC Fedora Script

The lxc rp…
