Re: Use UDP for (small) incremental zone transfers?

Sending from the correct email alias! Hi again. How many is "many"? A busy server will be handling many 1000s of queries per second. A few (tiny) zone transfers per minute will be background noise compared to that and the extra overhead of TCP will be negligible in comparison. IMHO it's not worth

I have a dns zone with many dns updates per minute. The updates are tiny, like 2-3 records, <500 bytes in total. Currently my secondaries receive a NOTIFY and they do a TCP connection to request a incremental zone transfer. We know that TCP is "heavy" and the data I need to transfer is tiny be

Hi Jeff. Query logging is quite an overhead and very heavy on writing to storage, so use it sparingly as it can have a detrimental impact on performance. For any moderately loaded server I would not have it enabled by default. Cheers, Greg On Thu, 12 Jan 2023 at 18:22, Jeff Sumner wrote: > I’ve

You can use "rndc stats" to have bind dump a file with stats in it. This is how I get stats from our servers. I store the values every 2 minutes and create a dashboard from that. Stuff like total queries, total queries from ipv4 clients, total queries from ipv6 clients, total A//CNAME/PTR

I’ve turned on query logging, then grepped for the count of lines logged in a particular second. Worked well enough for the job at the time. J De: bind-users em nome de "King, Harold Clyde (Hal) via bind-users" Responder A: "King, Harold Clyde (Hal)" Data: quinta-feira, 12 de jane
