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.
