# Gitea Access & Authentication Guide

This document defines the standard for accessing the Gluebox Gitea instance. Following these rules prevents the "uid: 0" (User Not Found) and "SSH Disabled" errors.

## 1. Primary Access: SSH (Recommended)
This instance runs as the `gitea` system user. Standard `git@` strings will prompt for a password and fail.

* **SSH Username:** `gitea`
* **Host:** `code.gluebox.com`
* **Verification:** Run `ssh -T gitea@code.gluebox.com` from your Mac. 
    * *Expected Success:* "Hi there, [user]! You've successfully authenticated..."
* **Clone Format:**
    ```bash
    git clone gitea@code.gluebox.com:tux/rsvp-system-core.git
    ```

## 2. Fallback Access: HTTPS & API Tokens
Tokens only work correctly when Gitea can resolve its own internal loopback.

* **Auth Header:** `Authorization: token <YOUR_TOKEN>`
* **Validation Test:**
    ```bash
    curl -H "Authorization: token <TOKEN>" [https://code.gluebox.com/api/v1/user](https://code.gluebox.com/api/v1/user)
    ```
* **Troubleshooting:** If the response returns `"uid: 0"`, the server's `LOCAL_ROOT_URL` is likely missing or the token was generated before the server was properly configured. Generate a fresh token.

## 3. Mandatory Server Configuration (`app.ini`)
The following values in `/etc/gitea/app.ini` are critical for maintaining access. If the server is moved or reinstalled, these must be verified:

| Section | Key | Value | Reason |
| :--- | :--- | :--- | :--- |
| `[server]` | `RUN_USER` | `gitea` | Matches the Ubuntu system user. |
| `[server]` | `OFFLINE_MODE` | `false` | Required for internal token verification. |
| `[server]` | `DISABLE_SSH` | `false` | Enables Gitea's internal SSH engine. |
| `[server]` | `LOCAL_ROOT_URL` | `http://localhost:3000/` | Fixes the "uid: 0" API bug. |



## 4. Maintenance & Troubleshooting
Since this instance uses the **Internal SSH Server**, Gitea manages keys in the database rather than a physical `authorized_keys` file.

* **Keys not working?** Go to **Site Admin > Dashboard** and run:
    * *Resynchronize pre-receive, update and post-receive hooks of all repositories.*
* **Auth Prompting for Password?** 1. Ensure your Mac's public key is added to **User Settings > SSH / GPG Keys**.
    2. Clear local Mac credential helpers: 
       `git config --global --unset credential.helper`
