[PHP]NOD32 AMC - automatic mirror creater

[admLoki]

Hi 2 all :) .Yesterday i browsed the Internet and founded a Perl script to create a local update mirror for NOD32.But i don't like him so i rewrote it in PHP :] .
Anybody can use it. One problem - i didn't implemented an update from official servers yet, but it will be soon .

<?php

Nice job :), this will automatically update NOD32, or what?

No, its creates a mirror for NOD32 .
For example, you updates your NOD32 from remote server .
But you have difficulties with speed/bandwidth etc. You runs this script on other server(in your local network,for example) and updates NOD32 from it :] .

[Daevius]

Ah nice, but shouldn't it be better if it was an executable? I mean, now the user needs to install a webserver etc to run the script ;). Nice job though :), as some really nasty software can block the internet for NOD32 so it doesn't get updated.

[admLoki]

I can use php2exe to make it executable, but then server will be static :[
Otherwise, why i need to make it executable ? If you have your own host you can run it under crontab and update your NOD32 from it without any problems :]

sounds cool. but i have no need and you may want to remove your sig as warez links are prohibited.
