## Opening tenma up to friends

Our server/intranet Tenma is currently underutilized, and it would be nice/fun/useful to open it up to select other people. This would only be available to friends, not a public service.

### Tenma Specs

- Storage: 2×12TB in RAID 1
- CPU: Ryzen 7 3700X (16 threads @ 3.6GHz)
- Memory: 64GB
- Network: Gigabit ethernet (Hetzner server in Finland)

### Things that Tenma can provide

#### Storage

As of 23-06-2025, 4.6TB free space. Could start by reserving 1TB, which would provide enough storage for 20×50GB for guests users, which would be plenty for a long time. Tenma also hosts a copyparty instance that could be opened to the public to some extent or another.

#### Bandwidth/hosting

Tenma has full web hosting infrastructure set up (hosting this blog among other things), so that would be easy to extend to other people as well.

#### VPS

In line with the previous 2 points; compute resources are currently underutilized.

#### Intranet

Tenma runs a Wireguard VPN network. You can use this to, for instance, access services between two connected devices without having to open them up to the wider internet.

#### DNS Server

Tenma runs a fully resolving DNS server, with some local entries for devices on the VPN network. This should probably be automated in some way, and the service should be augmented with DNSSEC before opening.

#### Git

Tenma has a Gitea instance

#### Livestreaming

Tenma has infrastructure proven capable of restreaming 1080p video and high quality audio to at least ~100 people although this is CPU intensive and requires activating a high bandwidth restreaming VPS that is usually kept disabled to save costs.

#### Other things

Some other services that currently run on Tenma or have run there before:

- Vaultwarden Bitwarden-compatible password manager server
- Soju IRC bouncer
- Syncplay server
- Video game servers (think Minecraft, Terraria, …)

### Considerations

- This would require Tenma’s internal documentation to be updated, adapted and publicized.
