That would be very useful.

If I understand the code correctly, dnsdist only falls back on it's
hardcoded ciphers etc. when none are set, right?
So at least on RHEL/CentOS/Fedora it should pick up the system
crypto-policies which can be freely configured.
I don't know if there's a similar mechanism for Debian/...

Best,
Christopher

It looks like we don't support that explicitly.. You could probably work
something around by tuning the allowed ciphers, but I guess an option to
to select the TLS versions allowed, like ssl_protocols in nginx or
SSLProtocol in Apache HTTPD, would make sense as well.

Thanks! Before I do that let me make sure it doesn't already exist in some
form.

We have a requirement to not allow negotiation of TLS version to go below
1.2. Is there a way to configure TLS so that it will only negotiate version
1.2 or above?

Regards,
brian

The usual process is to open a new feature request on our Github
repository [1], filling the corresponding parts of the template.
It provides the opportunity for other users to chime in and if the
feature makes sense to use it's usually added to the relevant milestone.

Hi,

Submitting an issue to https://github.com/PowerDNS/pdns would be a
first step. 

But it does not hurt to discuss the feature here. Maybe there's a
solution to your problem possible without a new feature.
