I have a server that has request-nsid yes; specified in the options block
within named.conf. However, I don't see the NSID responses in the resolver
channel log file. Anyone else see this behaviour? dig +nsid seems to work.

Regards,

Bob

Is that a functionality change from previous versions? I seem to remember
it working at the info level.

I could be wrong...

It only appears at debug level 3 or greater.

It appears to be due to an unintended change. I've submitted a patch to fix it

from the Bv9ARM: (9.11.3)

request-nsid
If yes, then an empty EDNS(0) NSID (Name Server Identifier) option is sent
with all
queries to authoritative name servers during iterative resolution. If the
authoritative
server returns an NSID option in its response, then its contents are logged
in the resolver
category at level info. The default is no.

Seems to suggest that they get logged at the info level.

Bob
