last question: the "/tmp"-dir is "drwxrwxrwt". is this the reason that "wwwrun" CANNOT remove a "root"-touched and owned file?!
The "t" at the end of the permission settings (called the sticky bit) deals with exactly the point discussed in the thread. Only the owner of a file may remove it. Important hint: this "sticky bit" behaviour is available on Linux and other UNIX-like operating systems, but not on all of them. E.g. on HP-UX (Hewlett-Packard's UNIX version), the sticky bit does not offer this protection.
