u/daviscompound

I have a url wpad.daviscompound added to blocked tab. Yet it still shows up in the logs. It is a NxDomain if that matters. To me shouldn't that not even show up in the logs?

I was updating and adding to my blocklists and found an issue. I had a blocklist that used to work but it was failing when update was attempted. I replaced that one with a new blocklist but what concerned me is the only way I knew it was failing was to look at the logs. It would be nice if technetium would have notified me without me accidentally finding it out. You might want to verify your blocklists are updating periodically.

About 24 hours in and 15.5.1 is looking good at my house. No anomalous server failure. Thanks ShreyasZare for such a brilliant piece of work. You rock!!!!!

Right now I have my technetium setup to forward to 1111,8888,9999 etc.

I have reading about using root hints instead for speed. From what I see you gain speed but lose some security.

Thoughts?

The .1 fixed the majority of server failures I was seeing. I am still getting a few errors a hour where I used to get none. One repeat failure is "features.opera-api2.com". It is failing ever time yet it can be resolved via 1.1.1.1 etc. This is very repeatable. Here is the error it throws.

{
        "Code": "EXTENDED_DNS_ERROR",
        "Length": "109 bytes",
        "Data": {
          "InfoCode": "Other",
          "ExtraText": "Resolver exception for features.opera-api2.com. A IN: Object reference not set to an instance of an object."
        }{
        "Code": "EXTENDED_DNS_ERROR",
        "Length": "109 bytes",
        "Data": {
          "InfoCode": "Other",
          "ExtraText": "Resolver exception for features.opera-api2.com. A IN: Object reference not set to an instance of an object."
        }

shreyasonline, I am running about 650 server errors a day and it is causing some issues. How do I safely and easily roll back from 15.5 to 15.4 until you get this fixed?

I just thought the Server Failures were fixed by clearing the cache. This morning they are rising by the minute. Normally they set at 0 and maybe hit one or 2 every once in awhile but not they are hitting close to 70 in the last hour.

Running 15.4

I have cache setup with defaults except for an increase in "Maximum Entries". My cache hits run about 35 percent. The question I have is, Is there a way to increase the hit percentage without sacrificing stability and reliability?

One of the things I use technitium for is blocking. I turned blocking off a couple of days ago and intended on turning it back on when I was done. That didn't happen. The only way I figured it out was all the sudden I was seeing things in my browser that shouldn't be there so I went to look at the blocking setting and ooops it was off....

It would be nice if on the desktop a warning that blocking is off or even something like changing the border of the blocked counter square red or text red or something like that... And I know you can set the timer for turning it on and off but ooops....

Oh and BTW thanks for GREAT piece of software.

I am currently running DNS Technitium forwarder using DNS-over-UDP.

However there other options: DNS-over-TCP, DNS-over-TLS, DNS-over-HTTPS, or DNS-over-QUIC.

I'm thinking UDP is probably the fastest as far as resolution because it does not have handshaking inherent in the other protocols. Am I right? Is there a reason why I would choose one of the other protocols?

I have 2 technitium servers running standalone. One server also serves dhcp. I am contemplating putting them in cluster mode I understand the how to do it but have a couple of questions. I think I know the answers but...

Will they still operate as a primary and secondary same as before. From what I understand the "cluster" basically is simply a sync of configuration and a single point front end to the configuration.

Will putting them in a cluster impact dhcp running on the master or will it continue to serve dhcp as normal?

I have seen where you can run dhcp on the secondary with a extended offer delay time. Will clustering impact that? Is there a way to keep things like reserved leases etc synchronized between master and secondary?

I have a non clustered primary and secondary technitium server. Dhcp serves them as primary/secondary to my windows clients. I noticed that the secondary gets queried quite often even though the primary is working fine. I wondered why. I found this info that explains it. Interesting.....

Windows resolves addresses based on response speed rather than priority. Since Windows 10, the OS queries all configured DNS servers simultaneously and uses whichever server replies first. If your secondary DNS is faster to respond, Windows will use it even if your primary DNS is active.

I have technitium setup on 2 machines. One as master and one as seconday. The dhcp server is on the master and serves the master as main dns and secondary as secondary dns. The display of top clients on the master displays the names of the clients due to dhcp providing the dns name for them. The seconday only displays the ip of the clients. How do I get the seconday to use the dns on the master to look up the local names?

The current Cache TTL is default set to 1 week. I increased my cache size to 14000 and it fills up and stays filled up. In a changing environment would it not be better to set the TTL lower so that it would have better change at hits?

I was contemplating of increasing the cache size but to do it I need to understand how much disk space the cache uses currently. The only setting I can see is Cache maximum entries which is set to 10000. Don't know how many entries are currently in nor how much space that takes up. Is there any way to get more granular information on cache usage?

Thanks....

I am seeing periodic server failures logged. Not a lot but a few every time I look at the dashboard. I have tried adjusting settings but they don't go away. It doesn't appear to affect the system though. The question I have is that a normal occurrence? Am I just chasing a ghost?

Is technitium clustering really a cluster or is it just 2 servers that share configs? I have always thought of a cluster as 2 servers that are just pieces treated like a single server environment. Am i mistaken in that the technitium "cluster" is just 2 separate servers that synchronize configurations? I am not saying that aint GREAT but is it really a "cluster"?

I would like to reserve an address manually so it will get the address on first connect. However, I can not find a way to do this. The reserved lease page does not all you to add a lease.

I commonly use Firefox and my common sites are Facebook and News sites. I have noticed Firefox locking up periodically for several seconds. I did not see that with Pi-hole. It appeared that if was on sites with a lot of ads. I looked up what pi-hole does when a site is blocked and it returns 0.0.0.0 whereas the normal setting for Technitium is "NX Domain" blocking. I tried the setting for "ANY address" which I believe replicates what Pi-hole does and the lockups seem to be gone. Anyone else noticed this?
