1. add/edit cilent
2. Remove client
3. Set bw limit to client
4. Generate the script file to be run in startup.

This was my first PERL script so if you are a perl guru please share your thoughts.

So why this post — a modest warning of my coming back. Get ready for  some new posts — mostly drupal ( drush, git, management etc.) ..   BEST OF LUCK TO ME

What i am expecting from you:

• You already have a running web server [ Xampp/WAMP/ Uniform server ]
• You know how to install Netbeans IDE 6.8 or it’s already running in your environment
• You know what is CodeIgniter
• You are not a complete Newbie

# STEP – 1

First add extension Xdebug in PHP. Download latest stable Xdebug version from Xdebug.org. Follow the procedures. If you are lazy like me and don’t want to read the whole thing [it's a bad habit ] copy the following settings and put at the end of your php.ini by not forgetting to change the path

zend_extension_ts="C:/wamp/bin/php/php5.2.9-1/ext/php_xdebug-2.0.4-5.2.8.dll"
xdebug.remote_enable=on
xdebug.remote_handler=dbgp
xdebug.remote_host=localhost
xdebug.remote_port=9000

Note: If anything messes up later; come back and study those links over and over till u understand the whole thing.

# STEP – 2

Configure CodeIgniter to accept ‘?XDEBUG_SESSION_START=netbeans-xdebug’. You can follow one of my post or check in codeigniter forums for accepting GET data in CodeIgniter.

Start Netbeans IDE. Goto Tools >> Options >> PHP >> General: and check for settings in Debugging section. By default the port should be 9000 and Session-ID ‘netbeans-xdebug’.

#STEP -3 [ FINAL ]

Let’s say, You have installed a ‘test’ CodeIgniter application in your web server. Now add that application as a project in Netbeans 6.8 . Goto Project properties by right clicking on the project ‘test’.  Now go to ‘Run Configuration’ and click ‘advanced’  select ‘Ask Every time’ in Debug URL.

Now Open your ‘welcome’ controller and press ‘Ctrl+F5′ which will request for the URL:

specify url

insert ‘http://localhost/test/’  and press ‘Ok’.  Next select `Server side PHP`.

Clicking in ‘Debug’ button will open ‘http://localhost/test/?XDEBUG_SESSION_START=netbeans-xdebug‘ In you default web browser.

Now check in status bar for:

And check in toolbar for:

If those 2 shows up then u have successfully installed Xdebug+Netbeans. Your IDE is ready to do some debugging. Take your cursor over a line on index function of welcome.php; press ‘F4′ this will execute php scripts till that cursor. Dont worry if index.php is opened up focusing on first line.

Now You can watch for variables or step into functions or step over. You can check your code line by line.

Read this link which have brief discussion on what options you have for Debugging .

My counting on steps could be wrong .. bt it looks nice 1-2-3. I tried not to explain a lot; so for more details study provided links.  I hope this will make your life more easier. Enjoy !!

It was way back when I first got my hand on linux in 2002. It was a Red-hat. My neighbour Zakir Uncle introduced it to me. He told me at that time, linux holds gr8 features and u can do so many things with it. But all I did was ( cd .. / cd. / mkdir / touch / ).  I removed linux after 1month cause it was boring( what do u expect from a 3month old experienced computer user? ). Later, I experiment with different linux versions ( fedora, mandrake); and did able to make it popular enough that my late cousin (she died in 2008), my little sister and even my aunt used linux. Just to play Shishanshu and Mahjong.

In February, 2009 jhoroTEK configured the network server at Skyinnova (experimental work), where we configured a central server with Fedora Core 10 and squid. Adnan made it a success. [ He was suppose to write an article on it. Hopefully he will put it sooner.] My  friend Harun-ur Rashid who is a B/W  re-seller in our area was using squid as a proxy server and tc for traffic shaping.  No visual admin section and no DHCP.  So I got the perfect opportunity to experiment at his place.

For the Reader:

It’s not a complete tutorial on Configuring a network Server using CENT OS rather an experience sharing.  If you can take the clues and see the rose line u will find the destiny .  My task is still on-going;  if you have better suggestion then drop a comment.

If you want more details or consultancy then contact me.

Follow me on twitter  @neotohin  to see which step i am right now and some tips .

Things in my hand:

1. An 1 mbps B/W from ISP provider
2. A Core-2-duo Machine ( server ), A Pentium 4 client Machine)
3. 1 switch,  1 hub
4. CentOS 5.2

Task :

1. Share the B/W with clients in sub-network
2. Traffic Shaping Each client will have different kind of B/W plan like  16KB to 64KB shared.
3. DHCP Server + MAC binding [ future PPP ]
4. Proxy Server
5. FTP, WEB server ( Simple extensions )
6. More interesting things to come

Let the Journey Begin ====================================

Now what is drush .. drush is a command line shell and Unix scripting interface for Drupal. as stated in here.  The most noteable features of drush from my point of view is :   module enable/disable, update script,  module download, cache clear. Just from command mode i can check latest version of module and dl them and enable them in just simple 3 to 4 commands.

I am not going to briefly explain drush functionality but will try to explain how to run drush in your system in this case Windows XP ( ) .  Here it goes:

• Download the latest version of drush from drupal
• Now open Command prompt and check and set initial settings.
  • Type ‘php’ and press enter if php command is not found then set php.exe path in your Environment
  • Also add the drush path into the environment path
  • By Closing and opening  command prompt again. check by typing ‘drush’
  • If by typing ‘drush’ shows error regarding drush.php open drush.bat file in an editor and  add the abosulute path of drush.php in that bat file.
  • This will fix the drush.php path problem.
• Let’s play with drush. Open command prompt again and traverse to a drupal installation for example:  ’cd d:/www/mydrupal’  and then type  ’drush status’. It will show initial settings of mydrupal installation. If it does not check for settings and environment path.

Drush has some nice extensions. You can play around with them. Here is another simple tip for you. If you study drush you will definately like “drush -v dl ” and ‘drush info” command. “drush info <module_name>” shows particular modules downloadable version and “drush -v dl” can help you to download and copy the file directly into your installation by just 1 single command. But to use ‘drush -v dl’ is little tricky. It uses gzip and tar command to extract the downloaded module file. You can download gzip and tar exe for windows from here.

It seems some ppl did able to use gzip and tar without any hasle but in my case i had trouble with tar. So i hacked into the core of drush and changed the tar command into izarce . If you face problem with tar then go with izarce. It worked for me.

Oops. To use izarce first install the command line version. Then add the izarce location into your environment path. THen goto drush directory and open file ‘drush\commands\pm\package_handler\wget.inc’.  Now find the line which says:

drush_shell_exec(“tar -xf $tarpath -C \”$path\”");

Now replace this with

drush_shell_exec(“izarce -e -d -p”. $path . ” $tarpath”);

It worked for me hope this does for you too. Have a nice drushed life.

[ N.B. At first i tried to use 7zip instead of izarce and gzip+tar but they have some absolute path issue; the solution of which i could not find. So, if you do know of any solution better than this do let me know.

For setting environment   press "windows key+ pausebreak" >> Advanced >> 'environment variable' >> now find variable path .. enjoy]

Target To achieve: 

http://localhost/myapp/mycontroller/mymethod/?possible=yes

create file MY_Input.php in your application/library/
[ Reason: SO that CI does not destroy GET Method ] 

<?php

class MY_Input extends CI_Input {

    function _sanitize_globals()

    {

        $this->allow_get_array = TRUE;

        parent::_sanitize_globals();

    }    

} 

$config['permitted_uri_chars'] = ‘a-z 0-9~%?=&.:_\-’;

$config['index_page'] = “”;

I have just opened an account in twitter. http://twitter.com/neotohin .. I don’t know how long i’ll survive but let’s see. 

Cooliris
Full-Screen, 3D — Cooliris transforms your browser into a lightning fast, cinematic way to browse online photos and videos.

 This takes image/video searching   in a new height. Must see.

FoxTab

It’s better than FastDial in sense of look … But i like them both.  

Let me know if you have seen such kind of innovative add-ons or application .. Do share.

From now on we are going to wear this T-shirt in our office.  Except in some formal meeting or other situation.
