/**************************** file: CountSpam.c written by Keith Oxenrider November 6, 2003 This program will auto generate a bunch of random email addresses and create a web page that contains them. It is intended to give spammers some headaches. Notes from its original purpose as a page counter: For use on the web as a cgi program. Is activated by calling the program as an image, i.e., to increment counter without having a visible display, invoke as follows: If the last character in the input string is an '!' then the counter will not be incremented, just displayed ****************************/ #include #include #include #include #include /*hardcoded path to directory to store count file, change here */ #ifdef Win32 char path[] = "countdata\\"; #else /* presumed *nix */ char path[] = "countdata/"; #endif /* IMPORTANT!!
