Re: DNSVIZ errors
Thank you for your help. it does give insights into the problem. if you check dnsviz history, this does not happen everytime. the bind version is BIND 9.20.8-1+0~20250416.117+debian12~1.gbp1ea9dd-Debian obtained from: https://www.isc.org/download/ —-> https://bind.debian.net/bind there are no firewalls or load balancers. these are directly connected to internet. i was running BIND 9.18 official debian package and got no errors like this.

DNSVIZ errors

Re: DNSVIZ errors
Hello Ondrej
There are multiple domains with the error. The idea is not to obfuscate
but give an example which covers all domains with these errors.
These errors are also intermittent.
This is not a permanent error. I have no errors in my logs. The dnssec
configuration is below:
dnssec-policy mypolicy {
nsec3param iterations 0 optout no salt-length 0;
keys {
ksk lifetime unlimited algorithm ecdsap256sha256;
zsk lifetime 60d algorithm ecdsap256sha256;
};
inline-signing yes;
};
this domain akritrim.net is not broken. its your lists.bind.org mail
server that was broken, which was fixed after i sent the email.
something in mailman/postfix was broken from your side.
the only thing broken on this domain and others is the scenario i mailed
before.
anyways, if you need anything specific let me know.
cheers

I wonder what’s the point of obfuscating the name making people unable

everywhere else in your email:

Anyway, you need to provide all the details about the domain name
configuration and the related logs. You can’t expect help without
sharing the full information about your problem.

Re: DNSVIZ errors
i didn’t receive your reply but saw this on lists archive so replying to you: Do be aware that Ondrej is a member of ISC, the organization that develops BIND. He is also one of the maintainers of the Debian release of BIND which you are using. Why should i be aware? Is he is a threat or something?? In general, claiming that everyone but you is wrong is not exactly a teamplayer mentality, and creates aversion towards getting you the help you're asking for. Not just Ondrej or the other developers ISC employs, the entire list really. I claim no such thing. Or going even further than that, any list, any support channel. Not even just voluntary ones like this, even paid support channels aren't going to like customers who act like that. Those are paid to help you and to be nice to you, yes, but don't be surprised if it diminishes the quality of the help you are to receive. I don’t share your views. Do consider it, in any case. I wont. from someone who cant even search the internet N.B.: A trademark office allowed you to get a trademark on the term "Intelligence"? TM is not a LEGAL symbol. again learn to google and not hurl accusations in public and make a fool of yourself.
