But haven't got a reply yet. I've looked at all the log files, particularly auth.log, although there were thousands of login attempts to SSH and FTP, but none succeeded.

And, the fact that you mentioned index.php suggests that you're running a lot more than just a basic Apache webserver; PHP is a likely candidate for security vulnerabilities by itself, and if you haven't patched for FreeBSD-SA-09:16.rtld, any local exploit will yield root. Installing /usr/ports/ports-mgmt/portaudit can be helpful.... Regards, -- -Chuck
