# Nixifying a new host
If you have a bunch of SSH keys in your SSH agent and get errors when trying to SSH into a fresh host, you may need to temporarily add the following config to your SSH config (obviously change the details for your case).
The key is the line "IdentitiesOnly yes" along with an identity file.
```
Host 188.245.194.78
User root
IdentityFile ~/.ssh/hetzner_personal_root.pub
IdentitiesOnly yes
```

# Development setup
## Setting up VSCode (and flavours)
We're using [Deno](https://deno.com) in the webring functions, so if you want proper editor support, you'll need to install the [Deno extension](https://marketplace.visualstudio.com/items?itemName=denoland.vscode-deno).
There's already a `.vscode` directory which should direct VSCode to enable the Deno extension for this project.

If you have a bunch of SSH keys in your SSH agent and get errors when trying to SSH into a fresh host, you may need to temporarily add the following config to your SSH config (obviously change the details for your case).

IdentityFile ~/.ssh/hetzner_personal_root.pub

```
## Deploying the webring
You should have a `.env` file with the id and deploy key for each script in the webring, as well as a key to deploy the index page to bunny.
When you have this, run `deno task deploy`.
