Okay, couple of points.
First, sha1lib is buggy, but it somehow tends to produce the correct info hash values. You can ignore those offset warnings.
Second, mysql_real_escape_string is missing in some older versions of PHP. You can edit the script you're accessing and replace all occurances of the function name with "mysql_escape_string" (delete the word "real" and one of the underscores around it).
And about btsethttpseeds.py. This is the python script included with the S-5-8-7/T-0-1-4 .zip or .tar.gz package from the downloads page. It modifies .torrnet files to support web seeds. The torrent is still part of the same swarm.
Finally, because I KNOW people are going to bug me about it, I'm putting this up:
http://dehacked.2y.net/BT/MakeWebSeedCGI.phpIt's dumb and hopefully self-explanitory.
Good night.
Could you please post php source for "MakeWebSeedCGI.php"? i'm like to modify HTTp Seeder and this one to work with eXoops downloads section. ThanX.
