Today I set up my old laptop as a Debian server, hosting Immich (for photos), Nextcloud (for files), and Radicale (for calendar). It was surprisingly easy to do so after looking at the documentation and watching a couple videos online! Tomorrow I might try hosting something like Linkwarden or Karakeep.
What else should I self-host, aside from HA (I don’t have a smart home), Calibre (physical books are my jam), and Jellyfin (I don’t watch too many movies + don’t have a significant DVD/Blu-ray collection)?
I would like to keep my laptop confined to my local network since I don’t trust it to be secure enough against the internet.
edit: I forgot, I’m also hosting Tailscale so I can access my local network remotely!
I run a small setup on a seperate server segment (2nd router behind my main router) so it is on the internet. I run nextcloud, an dendrite and conduit instance (matrix chat-server servers), a mastodon and go-to-social instance (fediverse), bitwarden (password manager), and others.
If there is a service that you do not want to be publically accessable by everybody but you do want to access from everywhere on the internet yourself, check out client-side TLS (https) certificates. The server does is accessable from the internet put only people who have a TLS certificate on their client signed by you can access it. For services that do not require incoming connections from other machines (e.g. nextcloud, bitwarden, … but no federated services like matrix-chat or the fediverse) that is a very good option to protect your servers.
