Thanks Rowland, I tried that just now, but as soon as I restarted samba,
the error occurred again a few seconds afterwards. The good news, I
suppose, is that it's easy to reproduce - each time I restart samba I get
the error :) But, it wasn't helped by adding "allow dns updates =
nonsecure" to smb.conf on one of my DCs.
I wonder if there is some error being flagged by the internal DNS sync
mechanism, instead of the port 53 listener - which would explain why it
happens when I start up samba, and why I can't see any relevant traffic
using tcpdump.. The comment above 'dnsupdate_nameupdate_done' says that it
is "called when dns update script has finished". If I did not get the
error, the code would instead continue to run, and log the message
"Completed DNS update check OK".
is there a way I can manually do whatever it is that a DNS update check
does, to see where the problem lies?
Lingpanda101 - I don't have a specific log level set, so I'm just using
whatever the default log level is. But, in the code I can see that these
messages are logged with debug level 0, so they would appear regardless of
what my log level was.
