			<content:encoded><![CDATA[<p>These day, I am trying install Red5 flash server on CentOS 5.x, it&#8217;s part of Openmeetings web conference application. When I am try to start Red5 server using red5.sh , the service won&#8217;t work, here the log :</p>
<p>Running on  Linux<br />
Starting Red5<br />
Error occurred during initialization of VM<br />
Could not reserve enough space for object heap<br />
Could not create the Java virtual machine.</p>
<p>After hour searching I found that the system limit memory usage, so the Red5 that based on java won&#8217;t start. Use ulimit command will resolve it, ah then we go to next step <img src='http://a3-system.info/blog/wp-includes/images/smilies/icon_biggrin.gif' alt=':D' class='wp-smiley' /> </p>
<p>ulimit -n 4096 -u 14335 -m unlimited -d unlimited -s 8192 -c 1000000 -v unlimited 2>/dev/null</p>
<p>This solution may be used for other application that give same error message <img src='http://a3-system.info/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>Today I have deal with my client to clean all chaos caused by Gumblar virus, It&#8217;s seem his root password was stolen and all web data infected with code. The virus code snippet is like this:</p>
<pre name="code" class="js">var D;if(D!='' &amp;&amp; D!='X'){D=''};var U=new Array();var p="";function u(){var aY=new Date();
</pre>
<p>The condition , all index file , index.html or index.php was injected. The virus code injected on last line of file. After couple hour browse I didn&#8217;t find any solution to this problem and this make me confused, it will horrible if I have to remove the virus code one by one. </p>
<p>After two hour doing experiment finally I found the way how to remove the virus, just use bash script , using &#8220;grep&#8221; , &#8220;find&#8221; , &#8220;cut&#8221; , &#8220;grep&#8221; , &#8220;xargs&#8221; and &#8220;sed&#8221;. <img src='http://a3-system.info/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>Recently I want to setup a FTP system which can used to access HTTPD file, the FTP user will can add / modify or delete file or directory on /var/www/html which it is the httpd document root. </p>
<p>I just follow the instruction from <a href="http://www.howtoforge.com/virtual-hosting-with-pureftpd-and-mysql-incl-quota-and-bandwidth-management-on-centos-5.3">howtoforge for Pure-FTPD with mysql support</a>. Recently I realize that tutorial dedicated to buid a FTP with no have relation with httpd.</p>
<p>When I try to login to my ftp it can login well but the user will be &#8220;read-only&#8221; because the FTP home folder owner is apache user. For example my FTP user cacti with home user /var/www/html/cacti.</p>
<p>To accommodate my needs I need to adjust some parameter on pure-ftpd config ( /etc/pure-ftpd/pure-ftpd.conf ) , find &#8220;MinUID&#8221; string and set it to apache UID / for example on my server apache UID is 48 , now set MinUID to 48. Restart your Pure-FTPD server and test it ^^</p>

<p>Actually I am doing checking the DNS server for some problem, one domain registered always suffer &#8216;lost the name server&#8217;. When I use DNS tool from http://www.kloth.net/services/dig.php I always got the DNS server found but can&#8217;t be contacted.</p>
<p> ; <<>> DiG 9.3.2 <<>> @localhost XXX.com A<br />
 ; (2 servers found)</p>
<p>Then I remove the miss configuration in named.conf of the DNS server , reload the named and then magicly the domain query was very smooth to query . . . is it related with non existing db file on DNS Server ?</p>

<p>When I use it, I got so many un convenience situation, so I think the thumbnail file format will be better if the format like this :</p>
<p>thumb_filename.file_ext</p>
<p>That file format help me so much in many situation. To change thumbnail file format, we need change the Image_lib file. First, change this line (approx  line 38)</p>
<p>var $thumb_marker		= &#8216;_thumb&#8217;;</p>
<p>In to</p>
<p>var $thumb_marker		= &#8216;thumb_&#8217;;</p>
<p>Second , change this line (approx line 264 )</p>
<p>$this->full_dst_path = $this->dest_folder.$filename.$this->thumb_marker.$file_ext;</p>
<p>In to </p>
<p>$this->full_dst_path = $this->dest_folder.$this->thumb_marker.$filename.$file_ext;</p>
<p>That&#8217;s it, the  thumbnail file name format will change <img src='http://a3-system.info/blog/wp-includes/images/smilies/icon_smile.gif' alt=':)' class='wp-smiley' /> </p>

			<content:encoded><![CDATA[<p>Every time I send email, the email always discarded by hosting mailer. Here the error :</p>
<p>Mail sent by user nobody being discarded due to sender restrictions in WHM-&gt;Tweak Settings</p>
<p>After couple time trying, I found the error was generated when  I use &#8216;mail&#8217; PHP function. When we use mail() function to send email,  we got &#8220;Sender: Nobody &lt;nobody@yourhosting.com&gt;&#8221; in email header. And that&#8217;s why my email always discarded by my hosting mailer.</p>
<p>I change the email send method by using SMTP ( using fsockopen()  ). Because I use CodeIgniter , the email send code will be like this :</p>
<p>$this-&gt;load-&gt;library(&#39email&#39);<br />
$config[&#39useragent&#39]    = &#39Code-Igniter-Mailer-^^&#39;<br />
$config[&#39mailtype&#39]     = &#39text&#39;<br />
$config[&#39validate&#39]     = TRUE;<br />
$config[&#39protocol&#39]     = &#39smtp&#39;<br />
$config[&#39smtp_host&#39]    = &#39localhost&#39;<br />
$config[&#39newline&#39]      = &#34;\r\n&#34;;<br />
$this-&gt;email-&gt;initialize($config);</p>
<p>$this-&gt;email-&gt;initialize($config);<br />
$this-&gt;email-&gt;from(&#39youremail@yourdomain.com&#39, &#39Your Name&#39);<br />
$this-&gt;email-&gt;reply_to(&#39youremail@yourdomain.com&#39, &#39Your Name&#39);<br />
$this-&gt;email-&gt;to(&#39someemail@somedomain.com&#39);<br />
$this-&gt;email-&gt;subject(&#39Email Subject&#39);<br />
$this-&gt;email-&gt;message(&#39Your Message Here.&#39);<br />

			<content:encoded><![CDATA[<p>As a web developer, you must be has known &#8216;firebug&#8217;, one fomous add-ons in firefox that really<br />
facilitated us in looking for the location of the &#8216;bug&#8217; in the code that we for.</p>
<p>Up until today, I am not still knowing what application that had similarity function like<br />
firebug and could be used in another browser outside firefox , the internet explorer for example.</p>
<p>Today when I want to upgraded my firebug (the version that I use was quite old, 1.05)<br />
I found the solution for application that have similarity function like<br />
firebug and could be used in another browser outside firefox, the application call<br />
firebug lite.</p>
<p>Firebug Lite actually developed by firebug team, firebug lite consisted of one java script file,<br />
one CSS file and several image file as accessories. I tried the off line version in my development environment<br />
and the results were satisfactory enough.</p>
<p>I attached screen shoot that I took from firebug lite website. For more information please visit the<br />
site firebug lite at <a href="http://getfirebug.com/lite.html">http://getfirebug.com/lite.html</a></p>
<p><img src="http://getfirebug.com/lite/ie6_css.png" alt="firebug lite on IE"><br />
