Terraria

A Terraria world is more fun when it keeps existing while you're asleep. Normally that means leaving a PC on for the whole playthrough and forwarding a port through your router, which is why most groups end up playing on whoever's machine happens to be awake.

This is a dedicated Terraria server running TShock, always on, at a fixed address your friends can save. Your world lives on backed-up storage rather than someone's desktop, and TShock adds the server-side tooling vanilla lacks: player accounts and permissions, regions you can protect from griefing, bans, and a long list of commands for running a world other people play in.

How do I connect?

Terraria is not a web app, so there is nothing to open in a browser. You connect from the game itself.

In Terraria: Multiplayer → Join via IP, then enter your server's address, your-username-terraria.direct.elfhosted.com, and its port when prompted.

The field says 'IP address', but a hostname works fine

Terraria's UI asks for an IP. Type the address above anyway; it resolves correctly on desktop and mobile. There is no fixed IP to give you: the address follows your server automatically if it moves between machines, which is exactly what you want.

Where do I find my port?

Your port is in your welcome email, and on your account page in the store. It is assigned to you and does not change, so once your friends have saved the address and port they never need to change either.

Your password

Your server ships password protected, because it is reachable from the internet and the address is predictable. The default is:

changemeelfie

Change it. It is the same for every new server, so until you change it, anyone who knows the convention can wander into your world.

Set TERRARIA_PASSWORD to whatever you like using ElfBot. Your server restarts and picks it up in a few seconds.

Change it with ElfBot, not in-game

The in-game /serverpassword command works, but only until the next restart, because the password is applied at startup from your settings. TERRARIA_PASSWORD is the one that sticks.

If you'd rather run an open server, set TERRARIA_PASSWORD to an empty value. Bear in mind that "nobody will find it" is not true of a public address.

Using your own domain

Prefer terraria.example.com to the address above? Point a CNAME at it from any domain you own:

terraria.example.com.  CNAME  yourname-terraria.direct.elfhosted.com.

(substituting your own ElfHosted username for yourname)

Then your friends connect to terraria.example.com on the same port. There's nothing to buy or configure on our side, because Terraria speaks raw TCP with no certificates involved, so a plain DNS record is all it takes.

How do I use it?

First launch takes a few minutes

Your world is generated the first time the server starts, and generating a large world takes several minutes. The server isn't reachable until it finishes. Later restarts load the existing world in seconds.

Worlds default to large. Set TERRARIA_WORLD_SIZE to 1 (small), 2 (medium) or 3 (large) via ElfBot before first launch. Changing it afterwards does nothing on its own, because the world already exists.

TERRARIA_WORLD_NAME names the world, and TERRARIA_SEED sets a specific seed if you want a particular world layout.

Becoming the server admin

TShock's permissions are separate from the game. On first join, the server log prints a /setup command with a one-time numeric code. Run that in the game's chat to claim superadmin, then create yourself an account with /user add. TShock's documentation covers accounts, groups and regions in depth.

Region protection is the feature most groups end up wanting: it prevents anyone (invited friends included) from editing the bits of the world you'd rather keep intact.

Backups

Your world is on backed-up storage, and TShock takes its own periodic world saves alongside. If something goes catastrophically wrong, the world file can be restored like any other file in your storage.

What this is not

Terraria's dedicated server is not modded Terraria: tModLoader is a different program and this isn't it. TShock is server-side only, so every player connects with an ordinary, unmodified Terraria client. That's a feature: nobody has to install anything.

What users say..

We're rocking some excellent ⭐⭐⭐⭐⭐ TrustPilot Reviews, and here's what some of our usersfriends say..

I am new here, but today I learned realized that Elfhosted is one of the best free and open source software communities I've seen, and FOSS communities have been at the center of my life since the 90s (Perl, PHP, Symfony, Drupal, Ethereum, etc.). Great open software built by great people who care = great community, and that is something special.

You've done an amazing job @Funky Penguelf with the platform you provide and this place has an awesome mix of active community caretakers and software creators that I've seen here so far like BSM, Spoked, LayeZee and other elf vengers. Keep up the energy, productivity and community and take time to enjoy it and appreciate each other!

As a happy Elfhosted customer—who also self hosts MANY things across about 10 severs (dedicated, VPSes, and VMs running on Synology), I wouldn’t switch to self hosting the services I get from Elfhosted. They just work with very little effort configuring things, and the support the owner and his team provides is second to none. Plus I love being part of a fledgling—but quickly growing—enterprise.

⭐⭐⭐⭐⭐ /u/jatguy. (Reddit)

I’ve been using this service for a while now, and honestly, it’s a game-changer compared to anything else I’ve tried for managing my media library. The support is fantastic—super quick, and if the staff aren’t around (which rarely happens), the community steps up right away. I can’t imagine going back to any other platform.

Before this, I had my own setup with a NUC, NAS, and tools like Sonarr and Radarr. It worked pretty well for a while, and my internet speed was high enough to stream without any buffering. But in the end, it wasn’t worth the time or headache of managing all the storage and keeping everything running smoothly.

Now, with this service, everything runs smoothly in 1080p+ with no buffering issues. The interface is really easy to use, which makes managing everything a breeze. Plus, having a whole community of smart people available for guidance is a huge bonus.

I was sold from the start, which is why I quickly upgraded from a 1-month to a 3-month subscription, and I’m planning to switch to a 1-year plan soon. This service totally pays for itself, and I’m sure you won’t be disappointed. It’s been really impressive.

Best possible options for anyone looking for the do-it-all option along with the best customer service ive experienced in this space so far. Id rate it a 6 if I could but its limited to 5/5...

(responding to a discussion re the cost of ElfHosted vs mainstream streaming / self-hosting):

I didn't know that the goal of this project was to compete with large companies running/renting entire DCs. I was under the impression that the goal of this project was to manage the updating of almost selfhosted applications on a shared platform with other users. Basically, be my sysadmin for me.

That being said, paying for services is the 'easy button'. There is a real world cost incurred for the time saved. Time is money. Time is the most valuable currency that exists. Once time is spent, it's forever lost, one cannot retrieve it again (yet). In my mind, there are 3 options for use of time with respect to: mainstream, selfhosting, elfhosted.

  • mainstream - my time is valuable and I don't want curated content and I don't care what content that I have the ability to consume. I only like what's popular.

  • elfhosted - my time is valuable, I want my own curated content without being forced to browse past the same damn entry 500 times just to find out that I can't watch the movie I want because it's not available in my current location or was removed last week from mainstream providers.

  • selfhost - I care about costs and I have nothing but time to waste or I want to learn about the backend of the systems involved. I'll pay for my own VPS/homelab, electricity, manage the OS, manage app updates, figure out how to make the apps talk nice to each other, create my own beautiful frontend.

I know how much my time is worth, does that reddit poster know how much their time is worth? Without knowing what you are worth, you can't make effective capital expenditures with respect to the time it will take to recoup the capital.

I know I don't need elfhosted at all for my use case. I choose to stay with elfhosted because it's my 'easy button'. It's an efficient capital expense for the amount of time it saves me managing my own hardware, apps and saves me electricity costs. I'm also in a situation where I don't have upload bandwidth from my home to serve HD content to myself remotely. If I lived back in a city, I would still be here. My time is worth $$/hr.
