This is a sample code to parse a config file in PHP
$mosConfig_CONFIG_IDE=Y
$mosConfig_HOST=localhost
while (!feof($fp)) {
$line = trim(fgets($fp));
if (ereg('\$mosConfig_', $line)) {
$line = ereg_replace ('\$mosConfig_',"",$line);
$pieces = explode("=", $line);
$option = trim($pieces[0]);
$value = trim($pieces[1]);
$value = ereg_replace ("^\'","",$value);
$value = ereg_replace ("\'\;$","",$value);
$config_values[$option] = $value;
}
}
fclose($fp);

FINDMAC
August 11th, 2007I have written a script to search for mac address on a cisco network – findmac 1.3b2
findmac is a utility written in Perl that helps administrators find out exactly which switch and which port a host is patched into. Only CISCO equipment with CDP enabled is currently supported. It is a very useful tool for administrators of large scale CISCO networks.
