We may see an early release for 1.5.0

July 12th, 2020

Due to the Dynamic DNS work that I have planned for 1.6.0 I'm considering committing the 1.5.0 release a few months early. Perhaps just after the OpenBSD 6.8 release which will come out between october and november some time. This way I give myself a bit more time for 1.6.0. I kinda dislike floating releases and prefer set dates but this is sorta a special event. I'll keep pondering around this and you may see a november release.


Updated chart of delphinusdnsd processes

July 12th, 2020


Delphinusdnsd surpassed 40K lines

July 10th, 2020

In delphinusdnsd -current..

40146 total
This number will go up and down, but wow, what a bloat. I'm currently enjoying the last incarnation of the forwarding code. I finally fixed it I hope (in the cache). The work is committed tomorrows snapshot may be stable for enabling the cache. It is activated in the forward "" {} with a "cache yes;" line. Off I go, see you later.


Delphinusdnsd 1.4.2 Released (minor fix)

July 9th, 2020

Even though the 1.4.2 tarball doesn't update the internal version string to 1.4.2 (I forgot this rolling it this morning), it does feature a slight DNS header query flags fix to REFUSED answers. This bug was found 6 days ago, so I finally was able to backport it. So, only 1 source file is different from 1.4.1 featuring a 3 line diff.


Working forwarding setup with delphinusdnsd and unbound

July 3rd, 2020

I have just check in my work, it will be in tomorrows snapshot or you can github it in 3 minutes. The work is far from finished but I got a working forwarding with a TSIG secure channel, utilizing 2 delphinusdnsd's and one unbound (bound to localhost). One delphinusdnsd takes on queries for forwarding and send them to the second delphinusdnsd upstream at my server. It's forwarding config looks something like this:

forward "to these hosts" {
        incoming-tsig no;
        destination port 8053 key newsecret;
;       destination 2a01:4f8:162:1167::2 port 8053 key newsecret;
        destination port 8053 key newsecret;
;       destination 2a01:4f8:a0:5135::2 port 8053 key newsecret;
So on port 8053 at the upstream server(s) is another delphinusdnsd that has a similar config only incoming-tsig is set to yes, and it will forward to localhost (some port). Thus far it works and it is quick too. I'm sure I'll iron out the bugs next week though. I'm very proud I got this working so far, I dedicated the entire month of july for this, so there is plenty of time to test this.


reply_refused fixed, (before would answer NOTIFY)

July 2nd, 2020

I have made a fix for reply_refused() it was giving bogus answers. here is a diff for the fix. As you can see it was a misplaced memset() and then it didn't answer authoritatively which I added.



July 1st, 2020

I have added a "Donate" link to the main page. If you use delphinusdnsd and can donate a little bit I'd be grateful. I chose what I do with this money (it mostly goes to my living), and I chose what to with the development of delphinusdnsd, in other words, the donation would be a gift, with no strings attached. If you donate over 100 EUR I'm going to allow you to link to a hyperlink with your name or your corporation. The link has to be in taste with this site. You can go to the donate page directly through here. Thanks!


Coding ambition for July 2020

June 30th, 2020

I'm hoping to be putting in a forwarding feature to delphinusdnsd. This is the next closest thing to having a recursive server but not really. My goal is to have TSIG protection and different ports as the forwarding destination. So a sample entry may look like:

forward "to these hosts" {
	incoming-key pass;
	destination port 53 key NOKEY;
	destination fcfc:fcfc:8::1 port 5353 key routerpass;
So this forces incoming questions to only reply when the incoming key pass matches (a TSIG key), and the destinations either have NOKEY or a set key. I hope I can get this finished in July, then there is a priority to do something else in August and I'll be back for September, October, November and December to get started on the Dynamic DNS Updates. The DNS Updates won't be finished for 1.5.0 but will be aimed for 1.6.0 release. I'm hoping to make use of the cooler months to get ahead. Perhaps to get non-DNSSEC Updates for 1.5.0 and work on the DNSSEC part in 2021.


New process in delphinusdnsd in the works

June 20th, 2020

As you may know delphinusdnsd is spread over several processes and the plumbing for the IPC is hard to do. So I'm introducing the CORTEX process. Here is a rough chart on how it looks like:

Each connection between the cortex is called a neuron. It is sorta like the brain of the human :-). I haven't lost my mind. This is just a way of making sense for me, so I don't fall asleep to it. I hope to have the cortex work finished and tried in around three weeks to a month.
