Title: Please help with Leechblocker
Post by: Spudman on 15 November, 2003, 16:09:37
I am using Leechblocker V2, but it dont block all users, it blocks some, but only half at the most. I know other hubs use this and have no problems, so maybe I am doing something to cause this script to fail? But as I said, it does work with some users???

Please help, fresh out of Ideas!!

I am running Ptokax V0.3.2.6 TD4, Robocop V4.0 and Leechblocker V2.

If you dont know what is wrong, maybe there is a better script for only allowing registered users to download file lists and files.

Thanks for any help.

---------------------
-- LEECHBLOCKER 02 --    for PtokaX TD4
---------------------
-- Created by SAMPLERman - HUB: samplerman.no-ip.info
-- 5/August/2003
-- Based on an idea by OpiumVolage and RabidWombat
-- And thanks AGAIN to RabidWombat for new ideas

-- This LUA script prevents users that are not registered in the hub (=aliens)
-- from connecting to other users (for downloading).
-- New users (=aliens) can chat, upload and be searched. They just can't download.

-- This way your previously private hub can again be public.

-- Optionally, the script also blocks searches (from nonregged users).
-- However, it is recommended that you allow everyone to search your hub, so that
-- new users know what they are missing.

-- NEW in version 02:
-- To allow an alien to download for 1 session, OPs can type this command:
-- !letleech

-- To do for next version:
-- Optionally, aliens can download off of other aliens

-- There are 2 kinds of hubs:
-- 1) Open hubs for sharing anything
-- 2) Small hubs that concentrate on a special interest (e.g. classical sheet music)

-- This script is NOT recommended for hub kind #1, where it is enough to
-- control how many GB users are sharing.
-- Because in hub type #1 there is no point in registering users, this script
-- should be adapted to make shared amount the criteria for letting download.
-- Even better, for hub type #1 users who share little should be allowed to download
-- from other people who share little.
-- Freedom is a strength of the Direct Connect community; please do not cut into
-- people's freedom except when absolutely necessary.
-- This script is only for closed hubs with a very specific subject.

Ok, I have been trying this but get syntax errors if copied as you have put it. I dont get syntax errors when I delete the from the end. Now I get no errors, but it dont seem to be blocking users??
