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.

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 5.9.87.75 port 8053 key newsecret;
; destination 2a01:4f8:162:1167::2 port 8053 key newsecret;
destination 85.10.199.4 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.

Donations
July 1st, 2020
I have added a "Donate" link to the main delphinusdns.org 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 1.1.1.1 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.
