seriously, wtf @cloudflare
https://github.com/ddclient/ddclient/issues/820
this broke my vpn because the dns was set to 1.0.1.1 instead of the actual ip.
(real ip obfuscated but you can clearly see it's different to 1.0.1.1)
thankfully there is a workaround for now
I may or may not be addicted to docker and nginx reverse proxy. From my home connection I'm hosting game servers, little web apps and tools, and this very mastodon instance. All behind Cloudflare's DNS proxy with their wonderful 15-year SSL certs.
Who would have thought Raspberry Pi tinkering would have led to this? (The whole point, right?)
A sub-subdomain from my Dynamic DNS subdomain resolves to fake IP address pool under a DNS resolver from this organization:
Baidu Netcom Science & Tech Co.
eg.:
own subdomain: subdomain.example.com (resolving to my own dynamic IP address)
fake subdomain: www.subdomain.example.com (resolving to unrelated IP addresses and changing quickly)
Found on https://dnschecker.org
DDNS provider is: https://freedns.afraid.org
Anyone has experienced this strange behaviour?
Cтандартный вариант использования #DDNS не требует устанавливать какого-либо клиента. Более чем достаточно на #linux’ах и системных тулзов:
Зарегистрироваться на DDNS сервисе, выбрав доменное имя и получив некий идентификатор (уникальный в пределах этого конкретного Dynamic DNS-сервиса).
На машине настраивается регулярное обращение по определённому URL, каким-нибудь curl.
В этом URL’е проставляется идентификатор пользователя на сервисе.
Веб-сервер на стороне DDNS-сервиса видит:
Этот идентификатор пользователя и сопоставляется с тем доменом, что выбран у пользователя. В результате становится ясно, какой IP’адрес проставлять отвечая на DNS-запросы про конкретный домен.
Как часто дёргать?Сервис DynDNS по этому URL’у со своим идентификатором можно дёргать и раз в 5-10 минут.
В крайнем случае, придётся эти 5-10 минут побыть без доступа к машине. Ожидая, пока же обнаружится смена ip’адреса. Однако, в большинстве случаев происходит эта смена глубокой ночью.
Что конкретно делать?Классическая инструкция про это всё для #linux выглядит вот так — https://www.duckdns.org/install.jsp
Создать файл «duck.sh» содержащий:
echo url="https://www.duckdns.org/update?domains=exampledomain&token=a7c4d0ad-114e-40ef-ba1d-d217904a50f2&ip=" | curl -k -o ~/duckdns/duck.log -K -
Где у каждого свои собственные:
domains=...token=...И поставить выполняться этот файл каждый пять минут:
$: chmod 700 duck.sh
$: crontab -e
$: */5 * * * * ~/duckdns/duck.sh >/dev/null 2>&1
Кстати, по идеи, желательно в создаваемых shell-файлах, прописывать шебанги — начинать файл со строчки вида:
#!/usr/bin/env bash
Но работать, в целом, должно и без этого.
Cloudflare Tunnels (formerly #ArgoTunnels) provide a really important service for privacy-minded self-hosters. It allows you to expose services running inside your home network to the #internet, without exposing your IP address or worrying about dynamic DNS.
A lot of people are uneasy about cloudflare - so I'm wondering if there are ANY alternatives that offer a similar ability?
How do YOU expose your services online?
Hi #SelfHosted community. I've figured out a lot of my setup. I now have a new domain, laniesplace.us, just for #HomeServer stuff. It's set up through Porkbun with Dynu for #DDNS. I've now got #Traefik, #TailscaleVPN, #Linkding, #Forgejo, #Dokuwiki, Code-Server, #Portainer, #Netdata, #Watchtower, #Cockpit, #Pihole, #MiniFlux, #TheLounge, #Filebrowser, #UptimeKuma, and the #Homer dashboard service installed. I'm now trying to set up #Authelia so I can have single sign-on to my services. For some, it's working now, but I can't seem to get Linkding to work no matter what I do. This is on a #RaspberryPi 500 with 8 GB RAM and a 512 GB SD card, running #Stormux, which is based on #ArchlinuxARM. Can anyone help? I'll reply to this post with all my relevant config files in separate posts. What's happening is this: Linkding is supposed to be available at bookmarks.laniesplace.us. When I go there, I see a 401 unauthorized error and a link to sign into Authelia. Once I sign in, though, it redirects back to the page with the 401 error. I've been trying to figure this out for hours with no luck. Files will be in replies to this post.

Configurar Dynamic DNS (DDNS) en OPNsense https://blog.elhacker.net/2025/01/configurar-dynamic-dns-ddns-en-opnsense.html #CloudFlare #opnsense #tutorial #manual #ddns #dns
Moving my dynamic DNS for my home broadband to @beasts account as it had stopped working on Dreamhost. After starting to write a python script like I was using before, I realised that a simple .netrc file with API credentials and one curl command in a crontab was all I actually needed! Simples! #ddns #dns #dynamicdns
With all the suggestions of using a dynamic #DNS solution, I decided to just write a script that will alert me to when my IP address changes.
This seems simpler to me as it doesn't require me to learn the ins and outs of using #DDNS for multiple domains that are pointing towards #Docker containers.
If it was just one domain, I'd take do it.
És genial que el propi router del proveïdor d'internet sigui qui envia la IP pública al servei #DDNS.
Anyone know of a good free DDNS provider? I've been using Google's DDNS service for years, but they're moving all of their domain services to Squarespace, and Squarespace doesn't offer DDNS.
So now I need to figure out some other way to do it.
#DDNS #DNS #Google #Squarespace
Because search is completely broken, I should probably just try asking here.
I'm looking for an alternative to using NOIP for my selfhosting journey. If there is a way to self-host an alternative I'm happy to give that a try and pay that cloud fee to a local company.
I have the three domain option at NOIP, but getting the 4th I need would mean jumping to the 10 domain tier, something that I'm not interested in doing.
I just spend a good bit of time setting up a #ddwrt router to use update it's IP (#DDNS) on #cloudflare
It's "built in" but took some time. So for anybody else that would like to try this... Here is the info: 
So, for anyone tech-minded out there, if I want to host my own @bitwarden account on a home server running #Apache, routed through a DDNS that has a #LetsEncrypt SSL cert running on it: does anyone know the overview to sett up a SSL reverse proxy to my local machine?
I have reverse proxies working for non-SSL connections to a few other apps I have running (CumulusMX, Podsync, Websockets), but the secure connections always fail. Rather not switch to nginx.
#DDNS if you got a service with "your own domain" feature, are you able to leave the main domain at a (different) hosting provider and a subdomain as DDNS?
Mudei da MEO para a Vodafone e estou com um problema. Alguém que perceba dos routers wifi6 da vodafone. Estou a tentar configurar o serviço de DDNS com os mesmos dados que tinha no router da meo que estavam a funcionar e agora dá erro de ligação como se pode ver na imagem. Alguma ideia de como desencravar isto?
Kennt sich hier jemand mit dem Themenkomplex Synology #NAS + #DDNS + #ReverseProxy aus? Ich versuche seit Stunden meine FreshRSS-Instanz auch außerhalb meines LANs mit SSL verfügbar zu machen ohne Erfolg.
