Hello, I keep getting this error when I run the build step. I think it's coming from the PowerDNS part. I'm not sure how to resolve it. If there is more detail that would help you please let me know.

Host: Ubuntu 20.04 VPS on Digital Ocean

The following errors appear, it appears there are no longer Debian jessie packages for powerdns:

Dear,

If ddns server fail, ... service down.
How can I setup secondary ddns server ?

would you any comments ?

Thank you !

I am having an error come up when I try to run docker-compose I copied my config file from the sample as stated in your guide and changed all the locations of the files and domains, am I missing something here.

ERROR: The Compose file './docker-compose.override.yml' is invalid because:
services.powerdns.ports is invalid: Invalid port "53/udp:53/udp", should be [[remote_ip:]remote_port[-remote_port]:]port[/protocol]

OS: Ubuntu 19.04

How to reproduce:

• Checkout Repository
• rename and modify override yml file
• call docker-compose --project-name ddns up -d --build

Hello,

such a nice project!
But in my case caddy is restating the hole time.

Hi,
I noticed earlier today that I could no longer resolve my Dyn DNS hosted on d.pboehm.de

DNS is giving server failures

{
  "Status": 2,
  "TC": false,
  "RD": true,
  "RA": true,
  "AD": false,
  "CD": false,
  "Question": [
    {
      "name": "casafreitag.d.pboehm.de.",
      "type": 1
    }
  ],
  "Comment": "Name servers refused query (lame delegation?) [104.45.7.23]."
}

(https://dns.google/resolve?name=casafreitag.d.pboehm.de&type=A)

And https://ddns.pboehm.de is giving 502 Bad Gateway.

Is the service down/terminated on purpose or will it be coming back online?

Best regards from Hamburg, Germany

I'm not sure which line here actually describes the error, but it seems to be the gin-tonic import near the top. I found a possibly related issue here: gin-gonic/gin#1139.

Is there some fix or workaround for this? I'm not very familiar with Go environment unfortunately.

Hello, I've been getting an error telling me that port 443 is in use by another process (my website which uses Apache2). Is there any way I can have it use a different port, or is 443 required?

AVM FritzBox runs into SSL errors on update due to the missing CA used by LE.

Quick Workaround:
Disable HTTPS in caddy http://{$DDNS_CADDY_DOMAIN}

However there is a option (I think) to disable the automatic 302 moved redirect:
If the json config is used it should be possible to disable the automatic https redirect therefore enabling the usage by AVM devices.
https://caddyserver.com/docs/json/apps/http/servers/automatic_https/

Is it possible to update analog to a Fritzbox also via a ddclient?

For example the Fritzbox configuration:

1. DynDNS-Provider: custom
2. Update-URL: https://domain/update/name/2aeoaqe39c73aebd4afc7b0d41420d83a12e2341
3. Domainname, username and password can be filled in freely.

Unfortunately I have not found any information about this. Unfortunately, I have not yet managed to try it out.
The syntax from my ddclient will be:

1. protocol=
2. ssl=yes/no
3. server=
4. login=
5. password=
6. URL

$curl https://ddns.pboehm.de/
curl: (60) SSL certificate problem: certificate has expired

Is it possible to install this DNS server on a Debian server without Docker installed?

Hey,
I think my ISP is doing something that makes your /update thingy see a falsified IP (http://myip.is and similar see a different one too)

How do you feel about adding an /update/{domain}/{token}/{ip} route to explicitly set IPs?

When i start the server and look into the log

caddy_1     | Your sites will be served over HTTPS automatically using Let's Encrypt.
caddy_1     | By continuing, you agree to the Let's Encrypt Subscriber Agreement at:
caddy_1     |   https://letsencrypt.org/documents/LE-SA-v1.2-November-15-2017.pdf
caddy_1     | 2018/05/12 15:24:11 user must agree to CA terms (use -agree flag)
caddy_1     | exit status 1
caddy_1     | Do you agree to the terms? (y/n): y
docker_caddy_1 exited with code 1

How can i fix this?

I want to swap out the ACME server that caddy uses.

What would I need to add/configure to allow caddy to use a different ACME server instead of LetsEncrypt?

ACME server: https://acme.htools.work/directory

More info: https://acme.htools.work/

Please note, I need to also call an argument into caddy to reuse the key. (See more if link)

The use case would be deploying this on a handshake domain. (handhsake.org)

Steps to reproduce:

1. Create a hostname by calling https://ddns.pboehm.de/new/ [hostname]
2. Try to create the same hostname again

The token is exposed within the error message:
{"error":"This hostname has already been registered. \u0026{<hostname (ommited)> 127.0.0.1 <token (ommited)>}"}

is there any way to disable certbot at startup? for situations where you already have the certificate, you don't need the creation and it's stopping the server to boot up.

Hello.

Is the domain supposed to use the server as its NS, or just point d.domain.com to the IP? I'm a bit confused because it seems as if I should point NS to the server IP, but the install guide doesn't mention configuring a zone file.

I' having trouble figuring out the layout of the automated deployment.

Where would I need to update the code to use pdns to secure the zone(s) on the DNS server. Can the remote-backend API be used to both secure the zone and add the TLSA record?

Ok, so here's what I have setup with my DNS Provider:
A: ns.domain.com -> IP of server
A: ddns.domain.com ->IP of server (Frontend)
NS: dyn.domain.com -> ns.domain.com

I assume that is correct from other tutorials.

Now in the configuration file, what would these values be?

I have given /bin/ddns executable permissions, but every time I restart pdns it fails. I think I might have the wrong version of pdns.

What version of pdns did you use for this project?

I thought my domain records were configured incorrectly, which is why I asked you how you set them up. This is actually the problem I was having the whole time.

Hi
Thank you for your work

I was just trying out ddns, but could not get past docker-compose

I get
`ERROR: for 6df584236687_ddns_powerdns_1 a bytes-like object is required, not 'str'

ERROR: for b7189245e311_ddns_caddy_1 a bytes-like object is required, not 'str'

ERROR: for powerdns a bytes-like object is required, not 'str'

ERROR: for caddy a bytes-like object is required, not 'str'
`

(full output bellow)

Is the code that is broken? I questioned if my editing of docker-compose.override.yml was the culprit, but same happens with the vanilla .sample

Any ideas on how to fix?

Didn't find time to dig in the code, but is there any rate limiting support (at least for creation & updates of existing records)?

If so, what are the defaults and how could I change them? I envision something like https://flask-limiter.readthedocs.io/en/stable/ (but of course for Go) - mainly the Moving Window strategy.

Hi!

When I run docker-compose --project-name ddns up -d --build I get those error messages:

Thanks in advance!

Hi and thanks for this nice project!

Launching this docker-compose on ubuntu gave me an error:

ERROR: .UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa9 in position 467: invalid start byte

I identified that illegal quote was used here in docker-compose.yml:

 PDNS_REMOTE_HTTP_HOST: "ddns:8053"

I corrected it and it worked nicely.

Hi,

I tried to deploy your scripts, but pdns fails to run once pipe.conf was created.

service pdns restart

Job for pdns.service failed because the control process exited with error code.
See "systemctl status pdns.service" and "journalctl -xe" for details.

Hi
First of all, thanks for this solution here - It's amazing!

What I need to do, is set a .htaccess and .htpasswd on the webdirectory (we want user to login first, creating a host). I know I have to go into the docker to see the directory, but if I try to connect to the docker container with:

docker exec ddns_ddns_1 /bin/bash

I receive an error:

OCI runtime exec failed: exec failed: container_linux.go:348: starting container process caused "exec: "/bin/bash": stat /bin/bash: no such file or directory": unknown

Can someone help me out here? And it would also be great to know where the created hosts are located (think will be in the powedns container), and the webdirectory.

Thanks in advance,
Patric

Awesome project. I am running it since months without any problem!

Now I would like to add some other proxy hosts to caddy (ddns/docker/caddy/Caddyfile). But when I am adding an other section to the Caddyfile and rebuild the docker containers the ddns frontend is not working anymore.

First assumption was that the Caddyfile was wrong (syntax) but I do not see a problem.
Than I checked the container list

and I am wondering about the missing port information for ddns container. When I remove the changes in Caddyfile and rebuild the containers everything is working - but the port information is still missing.
Caddy use ddns:8080 as target host. But How does it work when the container has no open port 8080?

Hi!
I wonder if you can build this container into hub.docker.com
Thanks!

Dear, I try to install on ubuntu20.04. but got error. how to do....
Thank you !

Hi
Congrats for this great job. I love it.
I was wondering if there is a possiblity to secure new host registration with a password.
The idea is to make it private and prevent random visitors to register their hosts.
Thanks!

the subdomain under d.example.com don`t get ip ,
what is the problem ?
how can I solve it

Hi! Thanks for this great project (and service). This issue is actually only for documentation purposes. Maybe there could be a place (in readme or wiki) for additional ddns client configuration docs.

I'm using OpenWRT for my router and wanted to update WAN IP on pboehm/ddns service as soon as possible and to avoid running cron job every X minutes to check if IP changed.

After some research I've found in OpenWRT forums those two relevant topics:

• https://forum.openwrt.org/t/ddns-scripts-why-are-they-so-huge/56376
• https://forum.openwrt.org/t/udhcpc-user-script-documentation-and-how-to-hotplug-for-dhcp-events/47952

Basically what you have to do is:

1. Make sure you have wget with SSL support opkg install wget ca-certificates
2. Create a file /etc/udhcpc.user with following contents

#!/bin/sh
if [ "wan" = $INTERFACE ]; then
	logger "$INTERFACE - $interface - $J_T5_source"
	/usr/bin/wget -q -O - 'https://ddns.pboehm.de/update/[HOST]/[TOKEN]?myip='${ip}''
fi
exit 0

3. Make it executable chmod +x /etc/udhcpc.user

That's it!
