Re: [dnsdist] Client query id in the dq-object?
Hi list A few months ago, I've asked the question below and wasn't able to find a solution in the meantime. Does someone has a hint, how to achieve this? Many thanks in advance.

My goal is to find a specific query-id (ex. ) and then use this (same) specific query-id also for the outbound query from dnsdist to the backend server. Any hints how to achieve this? Many thanks.

Which version are yor running? healthCheckMode wil only be available in 1.8.0, which is not released yet.

I have set healthCheckMode='UP' but: showServers show status as "up" whereas after setUp() the status is "UP". And it still does helathchecks and status goes "down" if the backend is down. What is wrong? The docs? Am I misinterpreting the docs? Bug? Thanks Klaus ___ dnsdist mailing list dnsdist@mailman.powerdns.com https://mailman.powerdns.com/mailman/listinfo/dnsdist
