Ask HN: What's lwHostsCheck.php

I was looking over an old VPN of mine and found this file in all the directories-- I feel like it's something that's been dropped all over the place-- does anyone know what the point of it is? I tried googling it- but it just returns pages that have it publicly accessible. Does anyone know why its being dropped and if so what framework is doing it? Cpanel? I am certain I did not put it there.

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>";
