Ubuntu 11.10 waiting up to 60 more seconds for network configuration 'problem'

-->
I upgaded my ubuntu 11.04 Natty to ubuntu 11.10 Oneiric Ocelot a few weeks ago. To handle some issues I have needed to modify /etc/network/interfaces file. After some modifations I get the message:"waiting up to 60 more seconds for network configuration" when booting.
I have found the reason of this is to have any interfaces in /etc/network/interface file as auto. To correct the problem just remove all rows and leave it as default like:

auto lo iface lo inet loopback

Another solution can be modify the script /etc/init/failsafe.conf>>This script is the script that control configuration of network interfaces when booting and if they are not all configured send the message above to the screen.. So let's take a look at that script:

# failsafe description "Failsafe Boot Delay" author "Clint Byrum <clint@ubuntu.com>" start on filesystem and net-device-up IFACE=lo stop on static-network-up or runlevel console output script # Determine if plymouth is available if [ -x /bin/plymouth ] && /bin/plymouth --ping ; then PLYMOUTH=/bin/plymouth else PLYMOUTH=":" fi # The point here is to wait for 2 minutes before forcibly booting # the system. Anything that is in an "or" condition with 'started # failsafe' in rc-sysinit deserves consideration for mentioning in # these messages. currently only static-network-up counts for that. sleep 5 # Plymouth errors should not stop the script because we *must* reach # the end of this script to avoid letting the system spin forever # waiting on it to start. $PLYMOUTH message --text="Waiting for network configuration..." || : sleep 10 $PLYMOUTH message --text="Waiting up to 10 more seconds for network configuration..." || : sleep 10 $PLYMOUTH message --text="Booting system without full network configuration..." || : # give user 1 second to see this message since plymouth will go # away as soon as failsafe starts. sleep 1 exec initctl emit --no-wait failsafe-boot end script post-start exec logger -t 'failsafe' -p daemon.warning "Failsafe of 120 seconds reached."

As we see and understood from the scripts commands: that script is controlling the waiting duration when booting.. The script keeps waiting us totally 111 seconds.. If your system doesn't need to wait  just insert a # character at the beginning of sleep calls or remove these rows. If your system needs to wait, but you don't wanna be wait this much, just change the values as you want.. Problem solved in either ways, but I recommend the first one..

Note: The values of sleep calls in your script may be different than my script, that is because of I have made a modification before in that script..
In my case, I solved my problem with two ways. In the second way the final look of my failsafe.conf script is given in the following:

# failsafe description "Failsafe Boot Delay" author "Clint Byrum <clint@ubuntu.com>" start on filesystem and net-device-up IFACE=lo stop on static-network-up or runlevel console output script # Determine if plymouth is available if [ -x /bin/plymouth ] && /bin/plymouth --ping ; then PLYMOUTH=/bin/plymouth else PLYMOUTH=":" fi # The point here is to wait for 2 minutes before forcibly booting # the system. Anything that is in an "or" condition with 'started # failsafe' in rc-sysinit deserves consideration for mentioning in # these messages. currently only static-network-up counts for that. sleep 5 # Plymouth errors should not stop the script because we *must* reach # the end of this script to avoid letting the system spin forever # waiting on it to start. $PLYMOUTH message --text="Waiting for network configuration..." || : sleep 10 $PLYMOUTH message --text="Waiting up to 10 more seconds for network configuration..." || : sleep 10 $PLYMOUTH message --text="Booting system without full network configuration..." || : # give user 1 second to see this message since plymouth will go # away as soon as failsafe starts. sleep 1 exec initctl emit --no-wait failsafe-boot end script post-start exec logger -t 'failsafe' -p daemon.warning "Failsafe of 120 seconds reached."

Modelling a Digital Communication System using Matlab

I modelled the digital communication system by a simple script. In first, if you haven't installed Matlab in your system yet, you can see my article about installation of matlab on Linux.
A digital telephone converts an analog signal(our voice) to a digital signal before transmission. While the analog signal takes on real number values, the digital signal takes on only a finite set of integer values. We can model these implementation effects and save memory by storing the digital as an integer data type rather than as type double. I did this by writing the script in the following. When I run I got the pics showing the script is nicely working in the below of the script..

%% ====== Sources ======</div> <div> % Load sampled (discretized time) analog sources</div> <div> % with double values between -1 and +1.</div> <div> load phonecalls</div> <div> % See and hear both sources together.</div> <div> % Note source clipping at -1 and +1.</div> <div> plot(source1,'r')</div> <div> hold on</div> <div> plot(source2,'b')</div> <div> ylabel('DOUBLE Values')</div> <div> title('{\bf Analog Sources}')</div> <div> legend('Source 1','Source 2')</div> <div> soundsc([source1,source2],Fs) % Stereo</div> <div> pause(4)</div> <div> %% ====== Source coding (quantization) ======</div> <div> % Digital signals (discretized values) with scaled</div> <div> % and quantized int8 values between -128 and 127.</div> <div> sig1 = int8(128*source1);</div> <div> sig2 = int8(128*source2);</div> <div> % See and hear both signals together.</div> <div> % Clipped values at -1 and +1 in the sources</div> <div> % saturate in the signals at -128 and 127.</div> <div> figure</div> <div> plot(sig1,'r.')</div> <div> hold on</div> <div> plot(sig2,'b.')</div> <div> ylabel('INT8 Values')</div> <div> title('{\bf Digital Signals}')</div> <div> legend('Signal 1','Signal 2')</div> <div> soundsc([double(sig1),double(sig2)],Fs) % Stereo</div> </div> <div> ------</div> <div> <div> As you see from the script I plotted the analog sources and the digital signals seperately. The</div> <div> plot are shown in Figures. Any other necessary explanations is in the comments in the</div> <div> script.</div> <div> I want to speak about some functions and commands these are we used in the script above.</div> <div> load: load workspace variables from disk.</div> </div> <div> <div> soundsc: Scale data and play as sound.</div> <div> pause: Halt execution temporarily.</div> <div> int8: Stored integer value of fi object as built-in int8

Android x86 Wifi-Wireless Problem

Hi guys! Nowadays most of the people have a trouble with Android x86 wifi-wireless problem.
To handle this I figured out a solution.
If you haven't tried Android on a pc, you may  wanna see my post about how to install android on pc.

Solution:
Open Android  and press Ctrl+Alt+F1 to open terminal then type the following rows:

netcfg        --to see what you have as connection devices in your computer
                    probably you see lo,eth0 and maybe eth1--
then type
netcfg eth0 up   --to open eth0-- after that type
netcfg setprop net.dns1 8.8.8.8
close the terminal by pressing Ctrl+Alt+F7

And have fun with your net connection.
This solution is worked for a friend. Maybe it will work for you too!.

Worldlist Maker with Python

Fistly, if you haven't installed python in your system, you can wanna read my post about installation of python on linux.
Some peoples, especially hackers and that who wanna be a hacker :)  needs wordlistmaker scripts to hack passwords. A wordlistmaker script required to be very fast and very efficient. Because, most wordlists have thousands of words. So I choosed the language as 'Python' due to its speed. As we know, python is faster than C, C++ , java and pascal etc. I wrote the script and it worked perfectly! You can see some photos in the following. If you want my Wordlist Maker, contact me by using my email which is given in the right sidebar..

How to Encrypt Files in Linux

To encrypt a file we are going to use gpg software. That software is a command line executable software. First you need to install it if it is not installed before in your pc. To do this open a terminal and type:

sudo apt-get install gpg

After that compress the file you want to encyrpt. And type in the terminal

gpg -c fodername.tar.gz

and then type your password twice. It's done :). Delete the file you encrypted. Use foldername.tar.gz.gpg file to access your files.
To pass the password and reach your files again type:

gpg foldername.tar.gz.gpg
