Re: Strange copying

Thanks for the quick feedback!

I very much think (and hope :-) that the mistake is on my side.
My configuration is not that long though. I show the two files of interest below. The strange copy happens to any file edited on the policyhost for the group DNS.
It actually happens to any group, but DNS failure didn't make my boss happy.
If you have the time, please help me.
I could send any extra info needed. I have tried with debug output, but the only info I get is that the file is being copied, ...not why. md5 wouldn't explain this, since the copy would not wait until 01:30 in the morning. The old file is saved, and has the time of when the cfengine replaced it in a correct way the last time.
By the way, I'm on Solaris 8 if that is of interest.


Kind regards,
Roger Harrysson

It sounds very much as though the mistake is on yur side. My guess is
that you are using checksum md5 copying and that you have some kind of
contradiction in your files. But without more info it is hard to
diagnose. There are no known problems with copying that could lead to
this behaviour unless you have made a mistake -- it's easily done.

I use cfenigne from cron. It runs every 30 minutes and works fine.
Mostly I copy files from the server if they have chenged on the cfengine server.
However, everytime a change a file on the server I get the copy done twice!
One time correct (at most 30 minutes after the change), but also one time at 01:30 in the morning.

Why this second copy when the file already is in place?

Can I stop this misbehavour?

The problem is that when I change a file on the client there should be no copy from the server, but there is.
AT 01:30 IN THE NIGHT! When noone is around to fix the problem.

We have currently taken away cfengine from all our servers, since we can not live with this risk.
Sad for such a good software.
