Apache Log, passwd, "known hacks"

[Michael A. Peters]

Have a server on my lan running as a yum mirror for my lan, running
rawhide. Other than the kernel, it gets updated pretty much daily.

Saw this in the log:

--------------------- httpd Begin ------------------------

*snip*

The server is behind a router firewall.
I do have a couple ports forwarded to it - for bittorrent (tcp) and for
ntpd (udp - this is also my lan time server) - not ports apache uses.

192.168.15.101 is my wireless router (not the router the server is
behind, the wireless does strictly my wireless clients) - what exactly
is the "known hack" it is referring to? I certainly haven't tried to
hack it, I suspect that that is a bogus entry, but I do want to make
sure someone isn't connecting through my wireless router and trying
stuff.

The "possible succesful probes" are clearly yum updates that happened to
contain the word "passwd" in the filename.

Is that something that should be filed as a false positive bug?
A password containing file would not have the mime type
application/x-rpm
