Good FOSS software and reliable service providers? Etc.
used a bash script and a cron job for a long time, now the whole topic is one of the projects i regularly rewrite whenever I want to get my hands dirty with a new programming language or framework.
Cloudflare DDNS updated by ddclient on my OpnSense router. Cloudflare happens to be my current domain registrar. Honestly, my IPv4 doesn’t change that often. And when I used to be on Comcast, they assigned a block of IPv6 addresses and the router dealt with that. Unfortunately, I now have Quantum Fiber who only assign a single IPv6 address, so I gave up on IPv6 for now.
terraform and AWS route 53 on a self hosted gitlab pipeline.
Afraid has a curl update. Cron job. It’s that simple.
My ip updates maybe once every three months or so, but what i did was just write a script that checks the current ip and updates the domain registrar. My domain is on cloud flare, and they have an API through which I can do it. It’s literally one POST request. There are solutions out there but I wanted a really simple solution I fully understand so I just did this. Script runs in cron every few hours and that’s it.
Any registrar worth using has an API for updating DNS entries.
I just found this with a quick search: https://github.com/qdm12/ddns-updater
exactly. I literally have a bash script that calls the API triggered by cron every 30 minutes. That’s it. Are people seriously using a freaking docker container for this?
It’s easy to set up and also keeps a history
Ah, a history would be nice. I’ve been thinking of keeping some stats to monitor when the connection goes down, and how often my IP changes.
Fortunately I’ve kept the same IP since i changed ISPs a few months ago.
Personally I still think docker is overkill for something that can be done with a bash script. But I also use a Pi 4 as my home server, so I need to be a little more scrupulous of CPU and RAM and storage than most :-)
I would recommend OVH for DNS, they have an API and are on the list for that tool. Also you can use the API to get lets encrypt certificates
Looks good. Thanks!
Ddclient has done the trick for me, and my registrar supports it with an API
I set it once like 6 years ago and forgot it wasn’t something pre-installed and configured until I saw your comment. I was reading through the comments looking for the “you don’t need to do anything, ddclient takes care of it”
Ixury for people that can have public IPs! :)
Yup, CGNAT blows.
Yeah, there are workarounds… And who knows, maybe its just safer than public ip… But definitely require some external fixture.
I guess you already know about the options, but for others:
Find the cheapest VPS out there and have a Wireguard tunnel between it and your home network. Run ddclient or similar on the VPS in case the public IP changes.
Wireguard or ssh tunnel with port forwards, both works.
I solve it by paying way too much for a block of static IPs.
Way too much for sure.
Just the business internet to get the foot in the door for a static IP 5x’s the cost of my Internet.
It’s actually cheaper to just have DC IPs and proxy through hosted containers. Which is kind of crazy.
Negative aspect is that DC IPs aren’t treated very nice.
Yeah this has been the biggest problem with hosting. For SMTP to work outbound you gotta have a good static IP. Everything else can be DDNSed. So either you get a business class connection or proxy through a VPS front end.
cloudflare + the dynamic dns plugin for opnsense.
I use ddclient but in a docker container. Works great with minimal config
Desec + Nginx Proxy Manager as a reverse proxy. Solves ddns and https with a letsencrypt wildcard cert.
Hadn’t heard about deSec until now, seems to be run by some cool privacy minded folks in Germany:
I use http://www.duckdns.org/
Me too. I use uptime kuma to send the api request. then I also get uptime status 🙂
That’s a great idea, I hadn’t thought of that
afraid still works like a charm. cloudflare is ok. duckdns is cool.
Have done it via bash scripts for years. Never had a problem. Since a few months i use https://github.com/qdm12/ddns-updater
