ub_result.was_ratelimited

Unbound
1

Hello,

  Is “was_ratelimited” intended to be undocumented? There’s no mention of it in libunbound(3).

  Thank you!

Hi Felipe,

That wasn't the intention; seems I missed to update the manpage when I
introduced the field.
It is now commited on master.

'was_ratelimited' will be true if ratelimiting is enabled in unbound
(via the ratelimit* options) that results in SERVFAIL answers back to
the client.
'was_ratelimited' will be useful then if you want to queue the query for
later.

Thanks for noticing!

Best regards,

Hello,

  What is the idea of this value? Is it that, if libunbound has met a threshold of concurrent requests, it will refuse to send out any further requests until some have finished?

  If so, is that threshold configurable?

  Thank you!

cheers,

Hi Felipe,

This was added to help users that have set a ratelimiting option towards nameservers (i.e. the ratelimit* options, not the ip-ratelimit* options) differentiate between SERVFAIL answers for other reasons and SERVFAIL answers because the ratelimit was engaged.
