To limit APT download

If you need to limit the apt-get / auto update, you can create /etc/apt/apt.conf.d/76download.
Put script bellow into it. Dl-Limit "25" means max download speed will be 25Kbps.


Acquire
{
Queue-mode "access";
http
{
Dl-Limit "25";
};
};

dpkg: serious warning: files list file for package `package’ missing, assuming package has no files currently installed

If you have this kind of warning message :

dpkg: serious warning: files list file for package `package’ missing, assuming package has no files currently installed.

You only need to remove and install again the 'package' .

sudo apt-get remove package
sudo apt-get install package

To limit your network traffic bandwidth

If you need to limit your network traffic bandwidth.
You need to install iproute-2.6.27-2.fc10.i386 in Fedora .
The original script is from
http://www.torrentflux.com/forum/index.php?topic=2743.0

To use it you need to have root privileged.
E.g.
$ sudo sh tc.sh upload

# Download limit (in mega bits)
DNLD=1000mbps # DOWNLOAD Limit

# IP address of the machine we are limiting the uploads on.

Sending simple email using python

Source http://snippets.dzone.com/posts/show/658

In my case, I can send simple email using smtplib but the I received empty/blank email which is without From/To/Body appeared on my email client (Thunderbird).

So you need to wrap your email with email.MIMEText as sample codes bellow:

import smtplib
from email.MIMEText import MIMEText

def sendTextMail(to,sujet,text,server="localhost"):
   fro = "Expediteur "
   mail = MIMEText(text)
   mail['From'] = fro
   mail['Subject'] =sujet
   mail['To'] = to
   smtp = smtplib.SMTP(server)
   smtp.sendmail(fro, [to], mail.as_string())
   smtp.close()
  
sendTextMail("toto@titi.com","hello","cheers")

Warning: mkdir() [function.mkdir]: Permission denied on Fedora

Source http://gallery.menalto.com/node/42302#comment-176477

The problem in my case was that I had the SELinux's security features enabled in my Fedora Core 4 setup. I switched SELinux to permissive mode by editing /etc/sysconfig/selinux -
putting SELINUX=permissive.

There's probably a nicer way than just disabling the security but I was after a simple solution. SELinux FAQ is here.

You need to reboot to make it effective.

Setting up Bridged Network

I need to set up bridged network for my VirtualBox guess OS to have a network connection attached to host interface.

So I install bridge-utils package :

$ sudo apt-get install bridge-utils 

I need to add some lines in /etc/network/interfaces

auto br0
iface br0 inet static
 address 192.168.10.102
 netmask 255.255.255.0
 bridge_ports eth0

You have to bring up br0 manually for now.

sudo /etc/init.d/networking restart
sudo ifup br0

I think, that's it. VirtualBox 2.1.0 doesn't need TAP or TUN interface.
br0 will recognized in the Host Interface list in network setting part for guess OS.
Due to I set my br0 to static IP, I also need to set my network interface in guess OS to static IP (e.g 192.168.10.101) .

Disable Touchpad on Gnome

It's annoying when you typing some thing suddenly your pointer fly-away somewhere else coz you inadvertently touch the touch-pad with part of your hand.

There are two way to disable/enable thouchpad in Gnome :
1. Go to menu on "System" -> "Preferences" -> "Mouse"
Click on "Touchpad" tab and [un]check "enable Touchpad" below "General" section.

2. Open Terminal [Command line box / console].
To disable, execute :

gconftool -t bool -s /desktop/gnome/peripherals/mouse/touchpad_enabled "f"

To enable, execute :

gconftool -t bool -s /desktop/gnome/peripherals/mouse/touchpad_enabled "t"
