Strange db-files in working directory

[Lou Goddard]

I've seen these files after forgetting to set the
permissions correctly on the working directory of bind.
You could make sure that Bind has write access to its own
directory.

I was thinking of something like that... I can't really tell what might =
have
happened, there are no truncated lines in those files. Then again, they =
are
a little smaller than the actual zone file.
It might, however, be related to some permission-weirdness we had on =
that
machine, or maybe a timeout from the master...=20

I was able to remove both files without problems. =3D)

Sorry, I should have thought of that.

To be honest, I haven't tried. =3D(
The machine runs z/OS, not a standard unix. I am not sure if there is a=20
C compiler installed; I am pretty sure I won't get permission to build =
BIND from
source. Also, IBM seems to have modified its version of BIND a =
little(1), so I am not sure
if - and how - it would work at all. Not to speak of nasty EBCDIC-issues =
I might encounter...
At least IBM has announced to port 9.3 to z/OS...

Thank you very much,
Benjamin

(1) Their version of BIND4 allowed you to include load-balancing into =
DNS,
and their BIND9 allows for a BIND4-compatibility mode.
