Experiments from the land of open source

If you use both Pear and Zend framework you may want to extend the Zend_Auth adapters to use all the containers shipped with the Pear::Auth package.
Let’s go to create the class implements the Zend_Auth_Adapter_Interface starting from the Zend_Auth_Adapter_Ldap class.

The first beta version of Minerva (Ldap Password Changer) at version 0.5 has been released!
Minerva is a very little and simple PHP application with only one scope: permit at your openldap accounts to simply change its password without use other application (such as a webmail) that you can have or not.
Download it and tell us what you think about it!
This version includes some enhancements and fixes.
Now the Pear::Auth package is used for authentication and the timeout for long running jobs was added.
The memory free and mysql database table check plugins were added.
In addition the installer was improved and FCKeditor library was updated.
Help and comments are always welcome, see http://www.ortro.net for full changelog and details.

Requirements:
- PHP5
- PEAR::Net_Nmap
- nmap
<?php
/**
* Scan network to retrieve hosts and services information.
*/
require_once 'Net/Nmap.php';
//Define the target to scan
$target = array('127.0.0.1','www.yourserver.com');
$options = array('nmap_binary' => '/usr/local/bin/nmap');
try {
$nmap = new Net_Nmap($options);
//Enable nmap options
$nmap_options = array('os_detection' => true,
'service_info' => true,
'port_ranges' => 'U:53,111,137,T:21-25,80,139,8080',//to scan only specified ports
);
$nmap->enableOptions($nmap_options);
//Scan target
$res = $nmap->scan($target);
//Get failed hosts
$failed_to_resolve = $nmap->getFailedToResolveHosts();
if (count($failed_to_resolve) > 0) {
echo 'Failed to resolve given hostname/IP: ' .
implode (', ', $failed_to_resolve) .
"\n";
}
//Parse XML Output to retrieve Hosts Object
$hosts = $nmap->parseXMLOutput();
//Print results
foreach ($hosts as $key => $host) {
echo 'Hostname: ' . $host->getHostname() . "\n";
echo 'Address: ' . $host->getAddress() . "\n";
echo 'OS: ' . $host->getOS() . "\n";
echo 'Status: ' . $host->getStatus . "\n";
$services = $host->getServices();
echo 'Number of discovered services: ' . count($services) . "\n";
foreach ($services as $key => $service) {
echo "\n";
echo 'Service Name: ' . $service->name . "\n";
echo 'Port: ' . $service->port . "\n";
echo 'Protocol: ' . $service->protocol . "\n";
echo 'Product information: ' . $service->product . "\n";
echo 'Product version: ' . $service->version . "\n";
echo 'Product additional info: ' . $service->extrainfo . "\n";
}
}
} catch (Net_Nmap_Exception $ne) {
echo $ne->getMessage();
}
?>
The code below allows to retrieve and execute all SQL statements defined in a SQL script file removing all comments.
<?php
$sql_file = 'test.sql';
$contents = file_get_contents($sql_file);
// Remove C style and inline comments
$comment_patterns = array('/\/\*.*(\n)*.*(\*\/)?/', //C comments
'/\s*--.*\n/', //inline comments start with --
'/\s*#.*\n/', //inline comments start with #
);
$contents = preg_replace($comment_patterns, "\n", $contents);
//Retrieve sql statements
$statements = explode(";\n", $contents);
$statements = preg_replace("/\s/", ' ', $statements);
require_once 'MDB2.php';
$mdb2 =& MDB2::connect('mysql://usr:pw@localhost/dbnam');
foreach ($statements as $query) {
if (trim($query) != '') {
echo 'Executing query: ' . $query . "\n";
$res = $mdb2->exec($query);
if (PEAR::isError($res)) {
die($res->getMessage());
}
}
}
?>
I have used Pear::MDB2 abstraction layer to interact with the database but the code above should work with any other db abstraction layer or PHP built-in functions.
The Net_Nmap Pear package is a simple interface for Nmap, the free and open source utility for network exploration or security auditing.
Net_Nmap can be used to auto discovery hosts and services in your network or simply to parse Nmap XML output.
You may install it on your system simply typing:
$ pear install Net_Nmap
or if prefer download it from the Pear web site.
