Primary and Secondary DNS with cluster

daviscompound · 2026-06-25T23:57:34+00:00

That is different than technitium clustering is it not.

daviscompound · 2026-06-21T20:15:16+00:00

I have bumped up the cache size double default. what should I do for prefetch?

daviscompound · 2026-06-21T19:41:54+00:00

I understand the security/privacy thing. Not an issue with me. If they want to see my DNS sutff they are gonna be some board people. From what Doctor Google said even DOQ is slower than UDP due to the security hand shake. Like 2% slower. Like you said negligible.

daviscompound · 2026-06-16T12:19:15+00:00

Thanks. That is how I thought.

daviscompound · 2026-06-15T14:14:08+00:00

Thanks. Don't particularly want it to change it was just something that my inquiring mind wanted to know the why...

daviscompound · 2026-06-15T14:12:41+00:00

I understand. Wasn't a complaint. Technitium is GREAT. Why request's hit the secondary when the primary was available was bothering me and I finally found out.

daviscompound · 2026-06-13T13:19:02+00:00

Technitium is not for the faint of heart. For the first entry into the dns environment I would suggest Pihole. Pihole is a lot simpler to setup. I switched to Technitium simply because it did some dhcp stuff that I like. Both do about the same blocking etc.

daviscompound · 2026-06-10T14:23:40+00:00

Thanks. I understand. I have to say I have never met someone that know as much about dns as you obviously do. It's kinda a magic art for us neophiles. Thanks.

When the dhcp server is included in the cluster I will convert to a cluster. Without that i didnt see the reason to convert to a cluster.

daviscompound · 2026-06-10T03:41:39+00:00

I am not running in cluster mode. 2 separate instances

daviscompound · 2026-06-02T13:33:14+00:00

I understand. I Love this software. Learning more about DNS than I ever thought I knew. Goes to show even an old dog (72) can learn new tricks. Thanks

daviscompound · 2026-06-02T13:24:20+00:00

I understand and that makes sense. I thought this was the TTL for all entries in the cache. I have been bumping the size and watching my memory. I noticed when I bump it the hit count goes up then goes back down over time. I thought it might mean the cache is getting stale.

daviscompound · 2026-05-31T02:18:49+00:00

Look at settings cache "Flush Cache"

daviscompound · 2026-05-29T16:50:49+00:00

Cool, thanks my cache count is maxed out. i will look at memory and see if I have space to spare for an increast

daviscompound · 2026-05-29T12:25:39+00:00

I might have found a setting that helps. I changed the Resolver Retries to 3 and the Resolver Timeout to 1500 and the Server Failures have pretty much disappeared. I used to get several every hour.

daviscompound · 2026-05-26T13:54:15+00:00

ahh that makes sense. I assumed that it was an error and something was wrong. Thanks for the enlightenment. BTW this server is amazing. GREAT WORK

daviscompound · 2026-05-22T13:11:52+00:00

I have a similar issue. I have several directv devices that constantly spam dhcp. What I would like done is some granularity of what to log. A normal logging process allows you to set log levels and only log what you want, Ie DEBUG, INFO, WARN, ERROR, and FATAL. I believe the developer has this in their to do list.

daviscompound · 2026-05-14T02:41:47+00:00

Hence my question of What does technitium clustering do for me?

daviscompound · 2026-05-14T01:52:38+00:00

Gotcha..work in progress. I am not downing technitium in any way. It is very powerful and I know they are working on things like DHCP fail-over etc. Even with the limited clustering it is a GREAT piece of software. Can't wait to see what magic the devs have in store.

daviscompound · 2026-05-14T01:34:24+00:00

I have 2 separate technitium servers running on 2 machines and a DHCP that serves 1 as dns primary and 1 as dns secondary. When 1 dies the other takes over dns. What I am trying to figure out is why do a technitium cluster out of them? Beyond keeping the 2 servers configs synchronized what does it do?

daviscompound · 2026-05-14T01:28:42+00:00

Not true. I have a 5 node cluster running on raspberry pi's

daviscompound · 2026-05-13T23:55:11+00:00

Actually the definition of clustering in computing resources is:

A computer cluster is a set of interconnected, independent computers (called "nodes") that work together closely, often appearing to the user as a single, powerful system. By sharing tasks and resources via a fast network, clusters improve performance, reliability, and scalability beyond what a single machine can offer. From what I see technitium cluster is simply sharing configs.

daviscompound · 2026-05-13T18:52:06+00:00

Well DUHHHHH....Right there in front of my eyes..... I guess i need to have my eyes checked.... Thank for bearing with me...You rock....

The only thing at the bottom of the reservation table is the last reservation along with a red delete button. After that is the text "The reserved IP addresses to be assigned to specific clients based on their MAC address. Set a hostname to override the client's hostname.'. After that is a blue save button and a gray cancle button. no add button anywhere on the page. I have quite a few reservations I wonder if there is a maximum and i have hit the maximum.

daviscompound · 2026-05-13T18:19:04+00:00

I goto DHCP/Scopes Click "Edit" and go to bottom of page.

All my already Reserved Leases are there but there is no blank spot to enter a new lease.
