Two instances of AdGuardHome ... though tempted to switch to the new Gravity.
If you've actually been hacked you want to get your data off to another computer and then wipe the hacked server. You can try and run a rootkit to see if it can detect any signs of being hacked.
Before using any files from the serer, check them carefully for virus and trojans.
If you just locked yourself out of the server by mistake, boot into single-user mode and reset your password.
Either way, unplug the network cable until you figure out if you've been hacked or not.
Do it in stages. First get it running without any reverse proxies, just connecting directly to the exposed ports. Once that's working, add in your proxy. Then finally add cloudflare tunnels.
Thanks for the reply. I was hoping this might be a way to allow servers without an internet connection to still deliver push notifications to clients.
This is cool! Do PWA push notifications bypass the need for the centralised Apple/Android services?
Synapse really isn't that bad unless you're joining big rooms. I held off for ages because I thought it was a pig, but I have it running (along with a bunch of other stuff) just fine on a minimal VPS.
Services that need a lot of storage, I host at home (Gonic, Jellyfin, Audiobook Shelf etc). Services where I care about availability when I'm away from home, I host on a VPS (Vaultwarden, Synapse, Wordpress, DokuWiki etc).
Cool project, thanks for sharing! I wish you were doing iOS, there's still not a great SubSonic client there.
Out of curiosity, how are you doing the mixes based on a song? Where do you get the list of similar songs from?
The standard is to retry for 5 days before bouncing emails as undeliverable (and send a warning message that the email hasn't yet been delivered after 4 hours). However, every server can configure it to be whatever they want, so there's no guarantee.
You can't just use any old provider as a secondary mx, you need a server which is configured to accept mail for your domain but not try and deliver it locally. It's pretty simple to set up. The biggest issue is that you need the same spam protections on the secondary as on the primary, as spammers will send directly to the secondary to try and bypass spam protections.
Personally, I always use rsync for these sorts of jobs. Works over SSH so don't need anything on the server except SSH, if the trasfer gets interrupted it will resume from where it left of. Overhead from SSH is pretty minimal, but if you really want thigns to go as fast as possible, you can setup an rsync server ...
If you don't want to use rsync, just use SFTP or SCP.
Use bind mounts instead of docker volumes. Then you just have normal directories to back up, the same as you would anything else.
In general, it's not a problem to back up files while the container is running. The exception to this is databases. To have reliable database backups, you need to stop the container (or quiesce/pause the database if it supports it) before backing up the raw database files (including SQLite).
I've been using Linkding for about six months and really like it. Simple, lightweight, uses SQLite. There's an official Firefox/Chrome plugin to make bookmarking links easy. And my favourite is the linkding-injector plugin. If you use the injector than everytime you search on Google/DuckDuckGo you get a sidebar which shows search results from Linkding. Surprising how often past me is trying to help out future me!
