I wrote a simple code/class for automatic get photos from flickr photostream (by service API) to compose randomly a nice miniature photowall (you can see an example on my homepage). First of all you can need API code (only key, we don’t need secret authentication). Now the code, my class file was called lib/fget.php in here we define variable, class and function construct: <?php class Flickr { //API Key you can get them on http://www.flickr.com/services/apps/create/apply/ private $apiKey = 'xxxx'; //We define our numeric username http://www.flickr.com/services/api/explore/?method=flickr.people.getInfo private $NSID = 'xxxx'; //File per page (max file 200 for free account) private $ppage = '400'; public function __construct() { } public function retrive() { //For get data we use REST method and serialize option $getdata = 'https://flickr.com/services/rest/?method=flickr.photos.search&api_key=' . $this->apiKey . '&user_id=' . $this->NSID . '&per_page=' . $this->ppage . '&format=php_serial'; //Get the data $result = file_get_contents($getdata); //De serialize for array use $result = unserialize($result); return $result; } } ?> Now include the class into a sample page: ...

In this example a squid installation will use RADIUS “squid_radius_auth” Squid RADIUS authentication helper to authenticate users. Get last version of squid radius auth helper at: http://www.squid-cache.org/contrib/squid_radius_auth/ Download: [leo@srv01 leo]# wget http://www.squid-cache.org/contrib/squid_radius_auth/squid_radius_auth-1.10.tar.gz Extract: [leo@srv01 leo]# tar -xvf squid_radius_auth-1.10.tar.gz Go to directory: [leo@srv01 leo]# cd squid_radius_auth-1.10 Compile: [leo@srv01 squid_radius_auth-1.10]# make gcc -O2 -Wall -g -c -o squid_rad_auth.o squid_rad_auth.c gcc -O2 -Wall -g -c md5.c gcc -O2 -Wall -g -c util.c gcc -g -o squid_radius_auth squid_rad_auth.o md5.o util.o Now the installation, for my needs, I wanna keep binary into /usr/lib/squid/ and configuration file into /etc/squid/ and I don’t wanna take man files then edit Make.inc like this: ...
