>Enter Yggdrasil This is perhaps the worst branding I've seen in awhile. It's impossible to say correctly without being taught, difficult to remember, and difficult to spell. It's almost like they don't want their efforts to be acknowledged.

The fact that the majority of replies on HN see no problem in the name tells you you have a problem with the name

I get rare IP changes (not sure when exactly as I don’t care much because Dynamic DNS is a thing), have the option of a 5€/month static IP, and have no ports blocked. Germany, Vodafone cable.

In France, it depends on the provider. The ones I've tried: Orange DSL would change the IPv4 fairly often, sometimes while using it during the day. Huge PITA. You could pay for a fixed IP. No IPv6 on DSL. I have no experience with their fiber offer. SFR used to have a fixed IPv4 on FTTH, but now they're rolling out CG-NAT. Which is even worse, because not even DynDNS can save you. Not sure if there's the option of pa…

I'm at OVH dsl. My IP has not changed in years.

The first sentence on the website says: > Yggdrasil is an implementation of a new name-independent routing scheme and functions as an end-to-end encrypted IPv6 network. Somehow I don't think this project is aimed at "normal, mainstream people"...

The set of techies and the set of nordic people are both minorities in the world - but they don't overlap.

Tbh, you don't have to be Nordic to have a basic grasp of mythology from around the world and Yggdrasil is pretty commonly known. Even if people just know it from Marvel comics or heavy metal or something.

Which docker images? I've been having trouble finding "simple" mail servers for incoming and outgoing. Stuff like postfix and dovecot make my eyes cross, I just want to point DNS at an IP and send and receive mail there, securely. It's not that I can't set those other ones up, I just don't want to, nor should I have to for a small service...

I've been using Zimbra 8 for years. Not a docker image but has a single install script and sits on ubuntu. It's a poor-mans enterprise email client for free. It's a bit chunky and when it doesn't fall apart it has a nice friendly client with support for mobile. Includes all the bells and whistles of spam assassin, dkim, briefcase etc. Mobile view is a bit dated but it works for elementary sending / receiving. The fre…

Is it for non profit? Maybe you can apply for a license that way?

Computers (even phones) have a enough spare computing power and bandwidth that a true, cooperative mesh network is probably possible now: Data routed through a mesh of local networks created by each device to taps which can route across long-range fiber and satellite comms.

Phones do not have enough spare battery power to be relaying messages on a mesh network.

phones probably spend 1/3 of a day (during night) being charged and plugged to the wall. You could have a mesh network that at any given time at least 1/3 of members is active - public key could have a timezone/timerange during what time note usually operates.

I've been using Zimbra's free edition for quite some time myself too, since v4 IIRC (back before it moved from TomCat to Jetty). Ran DayJob's mail server from it for a fair few years too.

> The free version has no backups which is a pain and …

I “simply” rsync the key parts off to my usual backup locations (where snapshots are made etc.)⁰. There are a few articles on how to do this floating around. The restore procedure is basically the same as transplanting a Zimbra instance from one install to another¹. For paranoia's sake I have a small extra VM that automatically restores itself from the latest backup daily, and I check occasionally to make sure it is running fine and has recent mail. That VM is not publicly addressable, but if my main instance dies irreparably I could make it so easily and flip DNS over to point its way, probably bumping up its RAM allocation too, losing at most what happened since the last backup. The VM actually thinks it is the “real” primary instance, even with the same local network addresses, as they live behind a split DNS arrangement. A copy of this VM can be used to test upgrades and other major admin to an extent too.

> makes me scared to reinstall...

I've found upgrades work smoothly, if you wait a bit after major versions to let the quick adopters iron out the issues first, so I've not had to completely fresh install. Just don't upgrade the base OS at the same time as Zimbra. For OS upgrade when an Ubuntu TLS release nears its own EOL or Zimbra's support for it does. I do by reinstall rather than upgrade but for Zimbra in the process things are the same as the backup restore operation. There has always been sufficient overlap between Ubuntu LTS lifetimes and what versions Zimbra supports that this has worked for me.

> makes me scared to … move away from

I've successfully used imapsync³ to move mail between various servers in the past, including into, out of, and between, Zimbra instances. Obviously that doesn't cover calendar data, config, and other features, if you use them, but for mail it is a good option. Regular syncing to something else could be an extra fall-back backup option too though I've only used imapsync for one-off bulk transfers.

> Zimbra 9 looks nice but licensing.

Same. Given how many times Zimbra has changed hands I'm surprised similar hasn't already happened sooner and I've had a good run with it! Maybe closer to 8's EOL others will start maintaining reliable builds of the OS parts, though I'm thinking I'll shift to something else next year. I've mainly stuck with Zimbra because it just works, given my needs have changed considerably over the years something lighter will probably be better and if I'm going to have to do more work (or pay, of course) to keep using Zimbra it is definitely time to properly reconsider the state of the many alternatives. At least we've got a decent amount of time to transition.⁴

[0] Hot rsync to local LAN backup first to speed up the part where the instance needs to be down, stop Zimbra, rsync to local LAN again to get a consistent backup there, restart, then soon after that the local backup is rsynced off to the offsites.

[1] Install same OS+Zimrba versions, stop, restore data from backup over the top, some steps to check/fix perms, off you go. Again, there are examples in the docs & forums.

[2] As [1] just with the new OS.

[3] https://github.com/imapsync/imapsync

[4] IIRC 8.x is due to EOL and stop getting security updates at the end of 2023, I'm intending to have something else in place by the end of 2022. If I have time to look around properly and make a decision by then, maybe I'll get around to it over the extended bank holiday weekend at the start of June.

Phones spend almost all of their time charging next to the owners wifi router which is always plugged in. It just makes no sense at all to use phones as mesh nodes.

I figure most people recognize it from Minecraft than wherever Mojang got it from.

where is it used in Minecraft? I've played that game for years and I don't know what you're talking about

> What is yggdrasil minecraft?

> Yggdrasil is the name of the authentication system that is currently used for authenticating user credentials for Minecraft. ... Mojang has said that this authentication system should be used by everyone for custom logins, but credentials should never be collected from users.
