Description Avi Kivity 2006-06-05 14:25:26 UTC

Description of problem:

system-config-bind modifies zones by rewriting their zone files.  Bind, 
however, manages dynamic zone files by itself.  Bind refuses to load if a zone 
file was changed while it was down, and writing zone files managed by bind 
while it is up will likely cause immediate corruption.

Version-Release number of selected component (if applicable):
system-config-bind-4.0.0-40_FC5

How reproducible:
(haven't tested since I'd like to keep my server working, but numerous 
attempts to edit zone files for dynamic zones have taught me to use nsupdate)

Steps to Reproduce:
1. Edit a dynamic zone (in /var/named/data)
2. Restart bind
3. bind won't load the changed zone.
  
Actual results:
No zone.

Expected results:
Zone.

Additional info:
Using dynamic updates for *all* zones seems a much better solution anyway: 
multiple admins can change entries in the same dynamic zone without 
corruption.  Editing text files may be fun for people, but machines aren't so 
good at it.

Comment 1 Jason Vas Dias 2006-06-05 17:15:50 UTC

Yes, s-c-bind should handle dynamic zones more gracefully - at least by doing
an 'rndc freeze -> ( modify zone file ) -> rndc unfreeze' , if not actually 
providing an interface to nsupdate. In the long term, a GUI interface to 
nsupdate allowing management of remote zones would be a desirable and is
planned. I'll implement the freeze/unfreeze for dynamic zones with the
next release. Meanwhile, a simple workaround is to select 'Server -> Stop',
then edit the dynamic zones, and do 'Server -> Start'. In my experience,
most BIND users do not use dynamic zones at all, so forcing all zones 
managed by s-c-bind to be dynamic is not an option.

Now fixed with system-config-bind-4.0.0-41.fc5, to be released to FC-5
Updates/testing today.

Comment 3 Fedora Update System 2006-06-07 23:41:12 UTC

system-config-bind-4.0.0-41.fc5 has been pushed for fc5, which should resolve this issue.  If these problems are still present in this version, then please make note of it in this bug report.

Comment 4 Avi Kivity 2006-10-31 14:17:13 UTC

I tested it and it's working, but I still think an nsupdate style solution 
would be much better.
