.htaccess file for http authentication

Linux

Create a .htaccess file with the following values

AuthType Basic
AuthName "Massagebook"
AuthUserFile /path/.htpasswd
Require valid-user


Now create a .htpasswd file using the following command

htpasswd -c .htpasswd username

now the system will prompt for password
after giving the password, it will be encrypted and saved in a file

:

For windows follow the same method
but the password will not be saved in encryted form but will be saved as it is in the .htpasswd file.

:

php_network_getaddresses: getaddrinfo failed: --Error

uncaught exception: Invalid JSON:
Warning: getimagesize() [function.getimagesize]: php_network_getaddresses: getaddrinfo failed: Name or service not known in


If you get this type of error please check whether you have host entries in your host/driver file.

# for i in `lsof -i :80 | grep http | awk {' print $2'}`; do kill -9 $i; done
# for i in `lsof -i :80 | grep http | awk {' print $2'}`; do kill -9 $i; done

Getting MAC Address using PHP

<?php
/*
* Getting MAC Address using PHP*
*/

ob_start(); // Turn on output buffering
system(‘ipconfig /all’); //Execute external program to display output
$mycom=ob_get_contents(); // Capture the output into a variable
ob_clean(); // Clean (erase) the output buffer

$findme = “Physical”;
$pmac = strpos($mycom, $findme); // Find the position of Physical text
$mac=substr($mycom,($pmac+36),17); // Get Physical Address

echo $mac;
?>
