I’m personally using Docker MailServer. It’s been working great for over a year now, but mailu seems to have some interesting features (I’m especially interested in the admin panel)

You’re probably behind a CGNAT, check out the other comments

Glad I could help :)

Your ISP might make you go through another layer of NAT. Can you find the WAN IP address of your router and compare it to your public IP address from a website such as ipinfo.io ?

If they do not match, you’re probably out of luck and will need to forward your port from an actually public IP in order to achieve what you want

More details : CGNAT (Carrier Grade Network Address Translation) is basically a second router between your router and the public internet. This second router is configured in the same way as your personal one, the main difference being that your ISP fully manages it. From the viewpoint of this second router, your WAN IP is a private IP, and you share one actual public IP with several other customers (the same way all devices on you LAN share one single WAN IP)

Performing port forwarding from the public internet to your LAN, when behind a CGNAT, would require you to be able to configure a forwarding rule in the ISP’s NAT, which you usually cannot do.

Something’s odd with the numbers from fediverse observer. Numbers shown in monthly graphs should be about 30 times higher than numbers shown in daily graphs, but they are about the same

I can recommend some stuff I’ve been using myself :

• Dolibarr as an ERP + CRM : requires some work to configure initially. As most (if not all) features are disabled by default, it requires enabling them based on what you need. It also has a marketplace with a bunch of modules you can buy
• Gitea to manage codebases for customer projects. It can also do CI but I’ve not looked into it yet
• Prometheus and its ecosystem (mostly promtail and grafana) for monitoring and alerting
• docker mail server : makes it quite easy to self host a full mail server. The guides in their doc made it painless for me to configure dmarc/SPF/other stuff that make e-mail notoriously hard to host
• Cal.com as a self hostable alternative to calendly
• Authentik for single sign-on and centralized permission management
• plausible for lightweight analytics
• a mix of wireguard, iptables and nginx to basically achieve the same as cloudflare proxying and tunnels

I design, deploy and maintain such infrastructures for my own customers, so feel free to DM me with more details about your business if you need help with this

I did not read the link, but two of my biggest concerns do not appear in the summary you provided :

• the burden of hosting an ActivityPub enabled service is often duplicated for each instance instead of being split between them (for example, my Lemmy instance has a large picture folder and database because it is replicating all posts from communities I’m subscribed to)
• it’s a privacy nightmare. All instance admins now have as much spying power as the single centralized service it is replacing

(Edit: typo)

I’m pretty sure they are actually hosting it. The tech is quite different (cofractal uses urls ending with {z}/{x}/{y}, while their tile sever uses this stuff that works quite differently)

They told me about hosting their own tile server earlier today. I’m really impressed by how fast they moved !

A pull request for a privacy page during the onboarding is in the works, and I’ve been working with them to update the settings page and documentation (with the goal of providing an easy way to switch map providers). They are also working on a privacy policy, and want to ship all of this in a few weeks as part of a single release.

Once again, I’m really impressed with how well they’re handling this

never stopped POSTing, even though I configured nginx to always respond 403 to anything from them for about a year now.

Lol, there are definitely some stubborn user agents out there. I’ve been serving 418 to a bunch of SEO crawlers - with fail2ban configured to drop all packets from their IPs/CIDR ranges after some attemps - for a few months now. They keep coming at the same rate as soon as they get unbanned. I guess they keep sending requests into the void for the whole ban duration.

Using 418 for undesirable requests instead of a more common status code (such as 403) lets me easily filter these blocks in fail2ban, which can help weed out a lot of noise in server logs.

Your sensitive data and logins are tied to email addresses, which are tied to domains. Lose your domain, someone can access everything.

I recently stumbled upon an article showing how bad this can be when the expired domains were used for important/serious stuff

I think they do get marked as dead after the Bodis subdomain does not act as a Lemmy instance. But I was wondering if a large number of instances “waking up from the dead” and acting maliciously could cause some trouble. Or would such “undead” instances pose no more threat to the fediverse than the same number of newly created malicious instances ? I’m mainly thinking about stuff like being in a privileged position to DoS most instances at once, or impersonation of accounts that used to actually exist on these “undead” instances

Is named actually running as the bind user inside the container ? Maybe a USER bind line below the RUN lines will help.

I’ll probably look into newer fancier options such as Caddy one day, but as far as I remember Nginx has never failed me : it’s stable, battle tested, and extremely mature. I can’t remember a single time when I’ve been affected by a breaking change (I could not even find one by searching changelogs) and the feature set makes it very versatile. Newer alternatives seem really interesting, but it seems to me they have quite frequent breaking changes and are not as feature rich.

That being said, I’d love to see side-by-side comparison of Nginx and Caddy configs (if anyone wants to translate to Caddy the Nginx caching proxy for OSM I shared earlier this week, that would make a good and useful example), as well as examples of features missing from Nginx. This may give me enough motivation to actually try Caddy :)

(edit : ad->and)

I don’t use nginx-proxy-manager, but if you want to share what you tried, I will try to help you figure what’s not working

It’s the clients (web/android app, probably iOS too) that are making these requests.

To the best of my knowledge, the Immich server inside the container is not making requests to the outside. It is merely sending a style.json to the client displaying a map, which then fetches tiles from the Cofractal URL inside this JSON.

Or you can quite easily configure nginx as your personal caching proxy with an arbitrarily long TTL/retention duration (you can check out my follow-up post for instructions on doing that)

I used to wonder what kind of nerd notices this kind of thing, now I’m one of them

Edit : If you want to join us :

• you can run Pi-hole which is a self-hosted DNS server that allow monitoring/blocking DNS requests from devices configured to use it. In its default configuration, it acts as a network wide ad/tracker blocker.
• On Android, you can install Rethink DNS. This will configure itself as a VPN on your device, forcing all traffic to go through it. This allows it to act as an on-device firewall that allow monitoring/blocking DNS requests and TCP/UDP connections. This is similar to the features of Pi-hole, but the fact that it’s on-device allows it to be app aware : the logs will detail which app is responsible for which connection, and the allow/block rules can be app-dependent. The app honestly goes beyond all my expectations :
  • it does a good job at being easy to use by default
  • it is very configurable which gives you a lot of control if you want/need/can handle it
  • You can configure it to route traffic (after applying firewall rules) to a Wireguard VPN or through Orbot. (Apps that act as VPNs are not compatible with each other : you can only have one active at a time)
  • You can even configure several Wireguard interfaces at the same time, and route specific apps through specific tunnels

I don’t use Traefik myself, but this documentation page seems to suggest that Traefik only allows in-memory cache (which would eat RAM and not persist across reboots). You can probably run Nginx with this config inside a container for the caching, then use Traefik to handle requests to immich.your-domain.tld/map_proxy/* with the caching proxy container.

What do you mean ? Can you give me the exact link that’s not working ?
