Seems somewhat harmless- its PHP source is:
echo "<h2>Server info</h2>";
echo "You're accessing: " . $_SERVER['HTTP_HOST'] . "<br>"; //or $_SERVER['SERVER_NAME']
echo "This server's Ip: " . $_SERVER['SERVER_ADDR'] . "<br>";
echo "This server's hostname: ";
if (function_exists('gethostname')) {
echo gethostname() ;
} else {
//for php < 5.3
echo php_uname('n');
}
echo "<br>";
