Run ‘dig +trace +all internet-dns1.state.ma.us’ which will show you the glue records then try ‘dig +dnssec +norec internet-dns1.state.ma.us @’ for all the addresses in the glue records. e.g. dig +dnssec +norec internet-dns1.state.ma.us @146.243.122.17 Mark > On 10 Feb 2021, at 14:50, sam

Do you know about mxtoolbox.com? It (and other similar sites) does a good job of diagnosing DNS-related problems. I use it now and then to check out my own sites, as it gives a "second opinion". In particular its "DNS Lookup' function reported the following for "internet-dns1.state.ma.us" Ty

Thanks Mark. However, the traceroute to the hostnamed failed for the same reason. Please note: [root@myhost data]# dig internet-dns1.state.ma.us ; <<>> DiG 9.11.4-P2-RedHat-9.11.4-9.P2.el7 <<>> internet-dns1.state.ma.us ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, s

Well you could try tracing the addresses of the nameservers for which there where errors reported. It could be as simple as a routing issue between you and these servers. > On 10 Feb 2021, at 13:25, sami's strat wrote: > > couldn't get address for 'internet-dns1.state.ma.us': not found > couldn

I'm running BIND 9.11 on a CentOS 7 VM/ BIND is giving me the wrong answer for a single domain. I've cleared cache, restarted BIND, restarted the server, and ensured that I don't have the referenced domain anywhere in my configuration hardcoded. Please note the following query: [root@myhost ~]

Re: Forward zone does not work when allow recursive is restrictive

2021-02-09 Thread Mark Andrews
“forward” does not mean “proxy". Additionally servers out on the internet make iterative queries. They are non-recursive *AND* follow delegations. Making a proxy work is more that just relaying the request and the response. BIND does not support proxying other servers. > On 10 Feb 2021, at 0

Hey there, I am having an issue forwarding DNS queries and was hoping, that one of you might be able to help me: I have the following setup: DNS-Server reachable from the internet, is authoritative for zone foo.com DNS-Server reachable only locally, should be authoritative for zone test.lab.fo

Trying again on SERVFAIL

2021-02-09 Thread Alessandro Vesely
Hi, is there a way to know that a query has already been tried a few minutes ago, and failed? It happens seldomly, but sometimes the DKIM mail filter gets a SERVFAIL when it tries to authenticate an incoming message. SERVFAIL occurs when DNSSEC check fails. Trying again is useless, it has
