Re: disabling stateful firewalls for DNS traffic

This is March, right? I probably should've tried this on one DNS server, instead of all of them. I removed state tracking on outbound to port 53 trafficand nothing could be resolved. And, couldn't fix without manual intervention, as cfagent (cfengine) couldn't resolve its policy server

By decaying I mean they take some percent of time off of the rtt of the name servers that aren't used when there is a successful query to the fastest. Eventually the slower servers will be faster than the fastest and get queried. That query will set the rtt again for that server and will go back t

Regarding HMAC-SHA256 and RSASHA512 key generation algorithm in dnssec-keygen

Dear Team, I am using RSASHA1 key generation algorithm for generating the KSK and ZSK. Today, I tried to generate the algorithm using RSASHA512 and HMAC-SHA256 algorithm. Key generation through RSASHA512 algorithm run successfully but while generating the keys through HMAC-SHA512 algorithm
