[-Q-]

I set up my new server with a PHP-based CMS system (CMSMadeSimple) and a PHPBB2 bulletin board. Everything seems to be working ok except that I noticed in my server logs the following error msgs:

As I can't find the specified directories the requesting IPs are looking for, can anyone clue me in as to what this means? And it's happening for a couple of different IP addresses, but they're all registered to the Australian region of the world and while I can't rule out people visiting my site from there, it seems very unlikely. Is there something nefarious going on or am I just a noob server admin overreacting?

Thanks in advance.
