Tutorial and Code snippets

Download the latest ClamAv from http://www.clamav.net, the latest version during I wrote this procedure is version 0.95.3

#tar -xvzf clamav-0.95.3.tar.gz 
#cd clamav-0.95.3 #groupadd clamav
#useradd clamav
#/configure
#make 
#make install 
#cd ..

After the installation when there is no error, you may run and test ClamAv

#clamscan -r -l scan.txt clamav-0.95.3

Updating the Database virus definition

#touch /var/log/clam-update.log
#chmod 600 /var/log/clam-update.log
#chown clamav /var/log/clam-update.log
#freshclam -d -c 6 -l /var/log/clam-update.log

Now you are ready to use ClamAV to your PHP script below is my sample script to scan files on my site, you can use the eicar_com.zip from www.eicar.org its a test virus file but its harmless.

$filetoscan="eicar_com.zip"
$output = shell_exec("/usr/local/bin/clamscan ".$filetoscan);
echo $output;
if (eregi('FOUND', $output)) {
    echo "Virus found on the file!"
}else{
    echo "no virus and file is safe"
}

1. goto http://java.sun.com/javase/downloads/index.jsp and 
download JDK 6

2. on the download page select Linux OS, just skip the create 
account window and click the download link for  jdk-6u18-linux-i586.bin

3. upload the jdk-6u18-linux-i586.bin to your linux server

4. create a folder for the java :   mkdir java

5. move the file to java folder :   mv jdk-6u18-linux-i586.bin java/

6. set he owner to root :  chmod +x  jdk-6u18-linux-i586.bin

7. execute the installer: ./jdk-6u18-linux-i586.bin  , press space bar 
to continue with more prompt and enter yes for agree

8. to test if java is installed just enter javac , if error command 
not found this means your java is not yet register in global path 
or environment

9. to set the path to Java enter this :  
export PATH=$PATH:/root/java/jdk1.6.0_18/bin

10 to reload the environment enter this: source /etc/profile

To set the path permanently you can do the step below

change to your home directory (ie: /home/myname) and type....

vi .bash_profile (note the fullstop before \'bash\'. This \'.\' makes it a hidden file)
then arrow down until you find the line that looks similar to this.....

PATH=$PATH:$HOME/bin

type i to enter \'insert\' mode,
(remember to use the \':\' between directory names).
Press the escape key to exit \'insert\' mode,
type :w to write the file
type :q to quit the vi editor

Ok hopefully this is useful to you, on my case I use VPS Linux RedHat and I don\'t get any error during installation, I just posted it here for my own reference only

How to do this?

Ever wanted to save arabic text on your mysql database with PHP? here are some few tips you need to do to get rid of ??? character

("Content-type: text/html; charset=utf-8"); ?>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />

<form accept-charset="utf-8" ...>

I sometimes forgot how to configure my SQLyog program to remote the MySQL database so I decided to put it here on my site just for reference

As default the MySQL database can be access locally on the same pc but how about you are going to access it from other pc on your network, a very simple steps are the following:

GRANT ALL ON *.* TO \'user2\'@\'localhost\' IDENTIFIED BY \'pass1\';
