[tlug] "wrong ans. name (. != umountnfs.sh)" etc. in named log

["Michael(tm) Smith" <smith@example.com>]

I'm seeing some odd messages in my named log; stuff like:

  wrong ans. name (. != umountnfs.sh)

And with names of various other shell scripts in place of
"umountnfs.sh". I assume it's some sort of cracking attempt, but
I've not seen any reports of it elsewhere. Has anybody else?

I'm running bind 8.4.6
