 # CHANGELOG
 
-**TBD (TBD):**
+## 0.17.0 (2022-XX-XX)
 
-**0.12.3 (2022-01-13):**
+### BREAKING
 
-**Changes**:
+- Log level option `log_level` was moved to a distinct `log` config section and renamed to `level` [#768](https://github.com/juanfont/headscale/pull/768)
+- Removed Alpine Linux container image [#962](https://github.com/juanfont/headscale/pull/962)
+
+### Important Changes
+
+- Added support for Tailscale TS2021 protocol [#738](https://github.com/juanfont/headscale/pull/738)
+- Add experimental support for [SSH ACL](https://tailscale.com/kb/1018/acls/#tailscale-ssh) (see docs for limitations) [#847](https://github.com/juanfont/headscale/pull/847)
+  - Please note that this support should be considered _partially_ implemented
+  - SSH ACLs status:
+    - Support `accept` and `check` (SSH can be enabled and used for connecting and authentication)
+    - Rejecting connections **are not supported**, meaning that if you enable SSH, then assume that _all_ `ssh` connections **will be allowed**.
+    - If you decied to try this feature, please carefully managed permissions by blocking port `22` with regular ACLs or do _not_ set `--ssh` on your clients.
+    - We are currently improving our testing of the SSH ACLs, help us get an overview by testing and giving feedback.
+  - This feature should be considered dangerous and it is disabled by default. Enable by setting `HEADSCALE_EXPERIMENTAL_FEATURE_SSH=1`.

+### BREAKING
+
+- Boundaries between Namespaces has been removed and all nodes can communicate by default [#357](https://github.com/juanfont/headscale/pull/357)
+  - To limit access between nodes, use [ACLs](./docs/acls.md).
+- `/metrics` is now a configurable host:port endpoint: [#344](https://github.com/juanfont/headscale/pull/344). You must update your `config.yaml` file to include:
+  ```yaml
+  metrics_listen_addr: 127.0.0.1:9090
+  ```

+
+- Add support for writing ACL files with YAML [#359](https://github.com/juanfont/headscale/pull/359)

+- Simplify the code behind registration of machines [#366](https://github.com/juanfont/headscale/pull/366)
+  - Nodes are now only written to database if they are registrated successfully
+- Fix a limitation in the ACLs that prevented users to write rules with `*` as source [#374](https://github.com/juanfont/headscale/issues/374)
+- Reduce the overhead of marshal/unmarshal for Hostinfo, routes and endpoints by using specific types in Machine [#371](https://github.com/juanfont/headscale/pull/371)
+- Apply normalization function to FQDN on hostnames when hosts registers and retrieve informations [#363](https://github.com/juanfont/headscale/issues/363)

+- Added Tailscale repo HEAD and unstable releases channel to the integration tests targets [#513](https://github.com/juanfont/headscale/pull/513)
+
+## 0.14.0 (2022-02-24)
+
+**UPCOMING ### BREAKING
+From the **next\*\* version (`0.15.0`), all machines will be able to communicate regardless of
+if they are in the same namespace. This means that the behaviour currently limited to ACLs
+will become default. From version `0.15.0`, all limitation of communications must be done
+with ACLs.
+
+This is a part of aligning `headscale`'s behaviour with Tailscale's upstream behaviour.
+
+### BREAKING
+
+- ACLs have been rewritten to align with the bevaviour Tailscale Control Panel provides. **NOTE:** This is only active if you use ACLs
+  - Namespaces are now treated as Users
+  - All machines can communicate with all machines by default
+  - Tags should now work correctly and adding a host to Headscale should now reload the rules.
+  - The documentation have a [fictional example](docs/acls.md) that should cover some use cases of the ACLs features
+
+### Features
+
+- Add support for configurable mTLS [docs](docs/tls.md#configuring-mutual-tls-authentication-mtls) [#297](https://github.com/juanfont/headscale/pull/297)
+
+### Changes
+
+- Remove dependency on CGO (switch from CGO SQLite to pure Go) [#346](https://github.com/juanfont/headscale/pull/346)
+
+**0.13.0 (2022-02-18):**
+
+### Features
+
+- Add IPv6 support to the prefix assigned to namespaces
+- Add API Key support
+  - Enable remote control of `headscale` via CLI [docs](docs/remote-cli.md)
+  - Enable HTTP API (beta, subject to change)
+- OpenID Connect users will be mapped per namespaces
+  - Each user will get its own namespace, created if it does not exist
+  - `oidc.domain_map` option has been removed
+  - `strip_email_domain` option has been added (see [config-example.yaml](./config-example.yaml))
+
+### Changes
+
+- `ip_prefix` is now superseded by `ip_prefixes` in the configuration [#208](https://github.com/juanfont/headscale/pull/208)
+- Upgrade `tailscale` (1.20.4) and other dependencies to latest [#314](https://github.com/juanfont/headscale/pull/314)

+- remove key-value based update mechanism for namespace changes [#316](https://github.com/juanfont/headscale/pull/316)
+
+**0.12.4 (2022-01-29):**
+
+### Changes
+
+- Make gRPC Unix Socket permissions configurable [#292](https://github.com/juanfont/headscale/pull/292)

+- Giving and gracefully accepting constructive feedback
+- Accepting responsibility and apologizing to those affected by our
+  mistakes, and learning from the experience
+- Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+- The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+- Trolling, insulting or derogatory comments, and personal or
+  political attacks
+- Public or private harassment
+- Publishing others' private information, such as a physical or email

+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our
+standards of acceptable behavior and will take appropriate and fair
+corrective action in response to any behavior that they deem
+inappropriate, threatening, offensive, or harmful.
+
+Community leaders have the right and responsibility to remove, edit,
+or reject comments, commits, code, wiki edits, issues, and other
+contributions that are not aligned to this Code of Conduct, and will
+communicate reasons for moderation decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also
+applies when an individual is officially representing the community in
+public spaces. Examples of representing our community include using an
+official e-mail address, posting via an official social media account,
+or acting as an appointed representative at an online or offline
+event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior
+may be reported to the community leaders responsible for enforcement
+at our Discord channel. All complaints
+will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and
+security of the reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in
+determining the consequences for any action they deem in violation of
+this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior
+deemed unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders,
+providing clarity around the nature of the violation and an
+explanation of why the behavior was inappropriate. A public apology
+may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued
+behavior. No interaction with the people involved, including
+unsolicited interaction with those enforcing the Code of Conduct, for
+a specified period of time. This includes avoiding interactions in
+community spaces as well as external channels like social
+media. Violating these terms may lead to a temporary or permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards,
+including sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or
+public communication with the community for a specified period of
+time. No public or private interaction with the people involved,
+including unsolicited interaction with those enforcing the Code of
+Conduct, is allowed during this period. Violating these terms may lead
+to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of
+community standards, including sustained inappropriate behavior,
+harassment of an individual, or aggression toward or disparagement of
+classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction
+within the community.

-## Overview
+## What is Tailscale
 
-Tailscale is [a modern VPN](https://tailscale.com/) built on top of [Wireguard](https://www.wireguard.com/). It [works like an overlay network](https://tailscale.com/blog/how-tailscale-works/) between the computers of your networks - using all kinds of [NAT traversal sorcery](https://tailscale.com/blog/how-nat-traversal-works/).

+Everything in Tailscale is Open Source, except the GUI clients for proprietary OS
+(Windows and macOS/iOS), and the control server.
 
-The control server works as an exchange point of Wireguard public keys for the nodes in the Tailscale network. It also assigns the IP addresses of the clients, creates the boundaries between each user, enables sharing machines between users, and exposes the advertised routes of your nodes.

-headscale implements this coordination server.
+A [Tailscale network (tailnet)](https://tailscale.com/kb/1136/tailnet/) is private
+network which Tailscale assigns to a user in terms of private users or an
+organisation.
 
-## Status
+## Design goal
 
-- [x] Base functionality (nodes can communicate with each other)
-- [x] Node registration through the web flow
-- [x] Network changes are relayed to the nodes
-- [x] Namespaces support (~tailnets in Tailscale.com naming)
-- [x] Routing (advertise & accept, including exit nodes)
-- [x] Node registration via pre-auth keys (including reusable keys, and ephemeral node support)
-- [x] JSON-formatted output
-- [x] ACLs
-- [x] Taildrop (File Sharing)
-- [x] Support for alternative IP ranges in the tailnets (default Tailscale's 100.64.0.0/10)
-- [x] DNS (passing DNS servers to nodes)
-- [x] Single-Sign-On (via Open ID Connect)
-- [x] Share nodes between namespaces
-- [x] MagicDNS (see `docs/`)
+`headscale` aims to implement a self-hosted, open source alternative to the Tailscale
+control server. `headscale` has a narrower scope and an instance of `headscale`
+implements a _single_ Tailnet, which is typically what a single organisation, or
+home/personal setup would use.
+
+`headscale` uses terms that maps to Tailscale's control server, consult the
+[glossary](./docs/glossary.md) for explainations.
+
+## Support
+
+If you like `headscale` and find it useful, there is a sponsorship and donation
+buttons available in the repo.
+
+If you would like to sponsor features, bugs or prioritisation, reach out to
+one of the maintainers.
+

+# ACLs use case example
+
+Let's build an example use case for a small business (It may be the place where
+ACL's are the most useful).
+
+We have a small company with a boss, an admin, two developers and an intern.
+
+The boss should have access to all servers but not to the user's hosts. Admin
+should also have access to all hosts except that their permissions should be
+limited to maintaining the hosts (for example purposes). The developers can do
+anything they want on dev hosts but only watch on productions hosts. Intern
+can only interact with the development servers.
+
+There's an additional server that acts as a router, connecting the VPN users
+to an internal network `10.20.0.0/16`. Developers must have access to those
+internal resources.
+
+Each user have at least a device connected to the network and we have some
+servers.

+![ACL implementation example](images/headscale-acl-network.png)
+
+## ACL setup
+
+Note: Namespaces will be created automatically when users authenticate with the
+Headscale server.
+
+ACLs could be written either on [huJSON](https://github.com/tailscale/hujson)
+or YAML. Check the [test ACLs](../tests/acls) for further information.
+
+When registering the servers we will need to add the flag
+`--advertise-tags=tag:<tag1>,tag:<tag2>`, and the user (namespace) that is
+registering the server should be allowed to do it. Since anyone can add tags to
+a server they can register, the check of the tags is done on headscale server
+and only valid tags are applied. A tag is valid if the namespace that is
+registering it is allowed to do it.
+
+Here are the ACL's to implement the same permissions as above:
+
+```json

+  // groups cannot be composed of groups

+# Connecting an Android client
+
+## Goal
+
+This documentation has the goal of showing how a user can use the official Android [Tailscale](https://tailscale.com) client with `headscale`.
+
+## Installation
+
+Install the official Tailscale Android client from the [Google Play Store](https://play.google.com/store/apps/details?id=com.tailscale.ipn) or [F-Droid](https://f-droid.org/packages/com.tailscale.ipn/).
+
+Ensure that the installed version is at least 1.30.0, as that is the first release to support custom URLs.
+
+## Configuring the headscale URL
+
+After opening the app, the kebab menu icon (three dots) on the top bar on the right must be repeatedly opened and closed until the _Change server_ option appears in the menu. This is where you can enter your headscale URL.
+
+A screen recording of this process can be seen in the `tailscale-android` PR which implemented this functionality: <https://github.com/tailscale/tailscale-android/pull/55>
+
+After saving and restarting the app, selecting the regular _Sign in_ option (non-SSO) should open up the headscale authentication page.

+# ACLs
+
+A key component of tailscale is the notion of Tailnet. This notion is hidden
+but the implications that it have on how to use tailscale are not.
+
+For tailscale an [tailnet](https://tailscale.com/kb/1136/tailnet/) is the
+following:
+
+> For personal users, you are a tailnet of many devices and one person. Each
+> device gets a private Tailscale IP address in the CGNAT range and every
+> device can talk directly to every other device, wherever they are on the
+> internet.
+>
+> For businesses and organizations, a tailnet is many devices and many users.
+> It can be based on your Microsoft Active Directory, your Google Workspace, a
+> GitHub organization, Okta tenancy, or other identity provider namespace. All
+> of the devices and users in your tailnet can be seen by the tailnet
+> administrators in the Tailscale admin console. There you can apply
+> tailnet-wide configuration, such as ACLs that affect visibility of devices
+> inside your tailnet, DNS settings, and more.
+
+## Current implementation and issues
+
+Currently in headscale, the namespaces are used both as tailnet and users. The
+issue is that if we want to use the ACL's we can't use both at the same time.
+
+Tailnet's cannot communicate with each others. So we can't have an ACL that
+authorize tailnet (namespace) A to talk to tailnet (namespace) B.
+
+We also can't write ACLs based on the users (namespaces in headscale) since all
+devices belong to the same user.
+
+With the current implementation the only ACL that we can user is to associate
+each headscale IP to a host manually then write the ACLs according to this
+manual mapping.
+
+```json
+{
+  "hosts": {
+    "host1": "100.64.0.1",
+    "server": "100.64.0.2"
+  },
+  "acls": [
+    { "action": "accept", "users": ["host1"], "ports": ["host2:80,443"] }
+  ]
+}
+```
+
+While this works, it requires a lot of manual editing on the configuration and
+to keep track of all devices IP address.
+
+## Proposition for a next implementation
+
+In order to ease the use of ACL's we need to split the tailnet and users
+notion.
+
+A solution could be to consider a headscale server (in it's entirety) as a
+tailnet.
+
+For personal users the default behavior could either allow all communications
+between all namespaces (like tailscale) or dissallow all communications between
+namespaces (current behavior).
+
+For businesses and organisations, viewing a headscale instance a single tailnet
+would allow users (namespace) to talk to each other with the ACLs. As described
+in tailscale's documentation [[1]], a server should be tagged and personnal
+devices should be tied to a user. Translated in headscale's terms each user can
+have multiple devices and all those devices should be in the same namespace.
+The servers should be tagged and used as such.
+
+This implementation would render useless the sharing feature that is currently
+implemented since an ACL could do the same. Simplifying to only one user
+interface to do one thing is easier and less confusing for the users.
+
+To better suit the ACLs in this proposition, it's advised to consider that each
+namespaces belong to one person. This person can have multiple devices, they
+will all be considered as the same user in the ACLs. OIDC feature wouldn't need
+to map people to namespace, just create a namespace if the person isn't
+registered yet.
+
+As a sidenote, users would like to write ACLs as YAML. We should offer users
+the ability to rules in either format (HuJSON or YAML).

+
+## Example
+
+Let's build an example use case for a small business (It may be the place where
+ACL's are the most useful).
+
+We have a small company with a boss, an admin, two developper and an intern.
+
+The boss should have access to all servers but not to the users hosts. Admin
+should also have access to all hosts except that their permissions should be
+limited to maintaining the hosts (for example purposes). The developers can do
+anything they want on dev hosts, but only watch on productions hosts. Intern
+can only interact with the development servers.
+
+Each user have at least a device connected to the network and we have some
+servers.

+11  | internal          | internal  | 100.64.0.11
+```
+
+In order to only allow the communications related to our description above we
+need to add the following ACLs
+
+```json
+{
+  "hosts": {
+    "boss-computer": "100.64.0.1",
+    "admin1-computer": "100.64.0.2",

+  },
+  "groups": {
+    "group:dev": ["dev1-computer", "dev1-phone", "dev2-computer"],
+    "group:admin": ["admin1-computer"],
+    "group:boss": ["boss-computer"],
+    "group:intern": ["intern1-computer"]
+  },
+  "acls": [
+    // boss have access to all servers but no users hosts
+    {
+      "action": "accept",
+      "users": ["group:boss"],
+      "ports": ["prod:*", "dev:*", "internal:*"]
+    },
+
+    // admin have access to adminstration port (lets only consider port 22 here)
+    {
+      "action": "accept",
+      "users": ["group:admin"],
+      "ports": ["prod:22", "dev:22", "internal:22"]
+    },
+
+    // dev can do anything on dev servers and check access on prod servers
+    {
+      "action": "accept",
+      "users": ["group:dev"],
+      "ports": ["dev:*", "prod-app-server1:80,443"]
+    },
+
+    // interns only have access to port 80 and 443 on dev servers (lame internship)
+    { "action": "accept", "users": ["group:intern"], "ports": ["dev:80,443"] },
+
+    // users can access their own devices
+    {
+      "action": "accept",
+      "users": ["dev1-computer"],
+      "ports": ["dev1-phone:*"]
+    },
+    {
+      "action": "accept",
+      "users": ["dev1-phone"],
+      "ports": ["dev1-computer:*"]
+    },
+
+    // internal namespace communications should still be allowed within the namespace
+    { "action": "accept", "users": ["dev"], "ports": ["dev:*"] },
+    { "action": "accept", "users": ["prod"], "ports": ["prod:*"] },
+    { "action": "accept", "users": ["internal"], "ports": ["internal:*"] }
+  ]
+}
+```
+
+Since communications between namespace isn't possible we also have to share the
+devices between the namespaces.
+
+```bash
+
+// add boss host to prod, dev and internal network
+headscale nodes share -i 1 -n prod
+headscale nodes share -i 1 -n dev
+headscale nodes share -i 1 -n internal
+
+// add admin computer to prod, dev and internal network
+headscale nodes share -i 2 -n prod
+headscale nodes share -i 2 -n dev
+headscale nodes share -i 2 -n internal
+
+// add all dev to prod and dev network
+headscale nodes share -i 3 -n dev
+headscale nodes share -i 4 -n dev
+headscale nodes share -i 3 -n prod
+headscale nodes share -i 4 -n prod
+headscale nodes share -i 5 -n dev
+headscale nodes share -i 5 -n prod
+
+headscale nodes share -i 6 -n dev
+```
+
+This fake network have not been tested but it should work. Operating it could
+be quite tedious if the company grows. Each time a new user join we have to add
+it to a group, and share it to the correct namespaces. If the user want
+multiple devices we have to allow communication to each of them one by one. If
+business conduct a change in the organisations we may have to rewrite all acls
+and reorganise all namespaces.
+
+If we add servers in production we should also update the ACLs to allow dev
+access to certain category of them (only app servers for example).
+
+### example based on the proposition in this document
+
+Let's create the namespaces
+
+```bash
+headscale namespaces create boss
+headscale namespaces create admin1
+headscale namespaces create dev1
+headscale namespaces create dev2
+headscale namespaces create intern1
+```
+
+We don't need to create namespaces for the servers because the servers will be
+tagged. When registering the servers we will need to add the flag
+`--advertised-tags=tag:<tag1>,tag:<tag2>`, and the user (namespace) that is
+registering the server should be allowed to do it. Since anyone can add tags to
+a server they can register, the check of the tags is done on headscale server
+and only valid tags are applied. A tag is valid if the namespace that is
+registering it is allowed to do it.
+
+Here are the ACL's to implement the same permissions as above:
+
+```json
+{
+  // groups are simpler and only list the namespaces name
+  "groups": {
+    "group:boss": ["boss"],
+    "group:dev": ["dev1", "dev2"],
+    "group:admin": ["admin1"],
+    "group:intern": ["intern1"]
+  },

+    // the administrators can add servers in production
+    "tag:prod-databases": ["group:admin"],
+    "tag:prod-app-servers": ["group:admin"],
+
+    // the boss can tag any server as internal
+    "tag:internal": ["group:boss"],
+
+    // dev can add servers for dev purposes as well as admins
+    "tag:dev-databases": ["group:admin", "group:dev"],
+    "tag:dev-app-servers": ["group:admin", "group:dev"]
+
+    // interns cannot add servers
+  },
+  "acls": [
+    // boss have access to all servers

+      ]
+    },
+
+    // servers should be able to talk to database. Database should not be able to initiate connections to server
+    {
+      "action": "accept",
+      "users": ["tag:dev-app-servers"],
+      "ports": ["tag:dev-databases:5432"]
+    },
+    {
+      "action": "accept",
+      "users": ["tag:prod-app-servers"],
+      "ports": ["tag:prod-databases:5432"]
+    },
+
+    // interns have access to dev-app-servers only in reading mode
+    {
+      "action": "accept",
+      "users": ["group:intern"],
+      "ports": ["tag:dev-app-servers:80,443"]
+    },
+
+    // we still have to allow internal namespaces communications since nothing guarantees that each user have their own namespaces. This could be talked over.
+    { "action": "accept", "users": ["boss"], "ports": ["boss:*"] },
+    { "action": "accept", "users": ["dev1"], "ports": ["dev1:*"] },
+    { "action": "accept", "users": ["dev2"], "ports": ["dev2:*"] },
+    { "action": "accept", "users": ["admin1"], "ports": ["admin1:*"] },
+    { "action": "accept", "users": ["intern1"], "ports": ["intern1:*"] }
+  ]
+}
+```
+
+With this implementation, the sharing step is not necessary. Maintenance cost
+of the ACL file is lower and less tedious (no need to map hostname and IP's
+into it).

+# Better route management
+
+As of today, route management in Headscale is very basic and does not allow for much flexibility, including implementing subnet HA, 4via6 or more advanced features. We also have a number of bugs (e.g., routes exposed by ephemeral nodes)
+
+This proposal aims to improve the route management.
+
+## Current situation
+
+Routes advertised by the nodes are read from the Hostinfo struct. If approved from the the CLI or via autoApprovers, the route is added to the EnabledRoutes field in `Machine`.
+
+This means that the advertised routes are not persisted in the database, as Hostinfo is always replaced. In the same way, EnabledRoutes can get out of sync with the actual routes in the node.
+
+In case of colliding routes (i.e., subnets that are exposed from multiple nodes), we are currently just sending all of them in `PrimaryRoutes`... and hope for the best. (`PrimaryRoutes` is the field in `Node` used for subnet failover).
+
+## Proposal
+
+The core part is to create a new `Route` struct (and DB table), with the following fields:
+
+```go
+type Route struct {
+	ID          uint64 `gorm:"primary_key"`
+
+    Machine     *Machine
+    Prefix      IPPrefix
+
+    Advertised  bool
+    Enabled     bool
+    IsPrimary   bool
+
+
+    CreatedAt   *time.Time
+    UpdatedAt   *time.Time
+    DeletedAt   *time.Time
+}
+```
+
+- The `Advertised` field is set to true if the route is being advertised by the node. It is set to false if the route is removed. This way we can indicate if a later enabled route has stopped being advertised. A similar behaviour happens in the Tailscale.com control panel.
+
+- The `Enabled` field is set to true if the route is enabled - via CLI or autoApprovers.
+
+- `IsPrimary` indicates if Headscale has selected this route as the primary route for that particular subnet. This allows us to implement subnet failover. This would be fully automatic if there is more than subnet routers advertising the same network - which is the behaviour of Tailscale.com.
+
+## Stuff to bear in mind
+
+- We need to make sure to migrate the current `EnabledRoutes` of `Machine` into the new table.
+- When a node stops sharing a subnet, I reckon we should mark it both as not `Advertised` and not `Enabled`. Users should re-enable it if the node advertises it again.
+- If only one subnet router is advertising a subnet, we should mark it as primary.
+- Regarding subnet failover, the current behaviour of Tailscale.com is to perform the failover after 15 seconds from the node disconnecting from their control panel. I reckon we cannot do the same currently. Our maximum granularity is the keep alive period.

+# Controlling `headscale` with remote CLI
+
+## Prerequisit
+
+- A workstation to run `headscale` (could be Linux, macOS, other supported platforms)
+- A `headscale` server (version `0.13.0` or newer)
+- Access to create API keys (local access to the `headscale` server)
+- `headscale` _must_ be served over TLS/HTTPS
+  - Remote access does _not_ support unencrypted traffic.
+- Port `50443` must be open in the firewall (or port overriden by `grpc_listen_addr` option)
+
+## Goal
+
+This documentation has the goal of showing a user how-to set control a `headscale` instance
+from a remote machine with the `headscale` command line binary.
+
+## Create an API key
+
+We need to create an API key to authenticate our remote `headscale` when using it from our workstation.
+
+To create a API key, log into your `headscale` server and generate a key:
+
+```shell
+headscale apikeys create --expiration 90d
+```
+
+Copy the output of the command and save it for later. Please note that you can not retrieve a key again,
+if the key is lost, expire the old one, and create a new key.
+
+To list the keys currently assosicated with the server:
+
+```shell
+headscale apikeys list
+```
+
+and to expire a key:
+
+```shell
+headscale apikeys expire --prefix "<PREFIX>"
+```
+
+## Download and configure `headscale`
+
+1. Download the latest [`headscale` binary from GitHub's release page](https://github.com/juanfont/headscale/releases):
+
+2. Put the binary somewhere in your `PATH`, e.g. `/usr/local/bin/headcale`
+
+3. Make `headscale` executable:
+
+```shell
+chmod +x /usr/local/bin/headscale
+```
+
+4. Configure the CLI through Environment Variables
+
+```shell
+export HEADSCALE_CLI_ADDRESS="<HEADSCALE ADDRESS>:<PORT>"
+export HEADSCALE_CLI_API_KEY="<API KEY FROM PREVIOUS STAGE>"
+```
+
+for example:
+
+```shell
+export HEADSCALE_CLI_ADDRESS="headscale.example.com:50443"
+export HEADSCALE_CLI_API_KEY="abcde12345"
+```
+
+This will tell the `headscale` binary to connect to a remote instance, instead of looking
+for a local instance (which is what it does on the server).
+
+The API key is needed to make sure that your are allowed to access the server. The key is _not_
+needed when running directly on the server, as the connection is local.
+
+5. Test the connection
+
+Let us run the headscale command to verify that we can connect by listing our nodes:
+
+```shell
+headscale nodes list
+```
+
+You should now be able to see a list of your nodes from your workstation, and you can
+now control the `headscale` server from your workstation.
+
+## Behind a proxy
+
+It is possible to run the gRPC remote endpoint behind a reverse proxy, like Nginx, and have it run on the _same_ port as `headscale`.
+
+While this is _not a supported_ feature, an example on how this can be set up on
+[NixOS is shown here](https://github.com/kradalby/dotfiles/blob/4489cdbb19cddfbfae82cd70448a38fde5a76711/machines/headscale.oracldn/headscale.nix#L61-L91).
+
+## Troubleshooting
+
+Checklist:
+
+- Make sure you have the _same_ `headscale` version on your server and workstation
+- Make sure you use version `0.13.0` or newer.
+- Verify that your TLS certificate is valid and trusted
+  - If you do not have access to a trusted certificate (e.g. from Let's Encrypt), add your self signed certificate to the trust store of your OS or
+  - Set `HEADSCALE_CLI_INSECURE` to 0 in your environement

+# Running headscale behind a reverse proxy
+
+Running headscale behind a reverse proxy is useful when running multiple applications on the same server, and you want to reuse the same external IP and port - usually tcp/443 for HTTPS.
+
+### WebSockets
+
+The reverse proxy MUST be configured to support WebSockets, as it is needed for clients running Tailscale v1.30+.
+
+WebSockets support is required when using the headscale embedded DERP server. In this case, you will also need to expose the UDP port used for STUN (by default, udp/3478). Please check our [config-example.yaml](https://github.com/juanfont/headscale/blob/main/config-example.yaml).
+
+### TLS
+
+Headscale can be configured not to use TLS, leaving it to the reverse proxy to handle. Add the following configuration values to your headscale config file.
+
+```yaml
+server_url: https://<YOUR_SERVER_NAME> # This should be the FQDN at which headscale will be served
+listen_addr: 0.0.0.0:8080
+metrics_listen_addr: 0.0.0.0:9090
+tls_cert_path: ""
+tls_key_path: ""
+```
+
+## nginx
+
+The following example configuration can be used in your nginx setup, substituting values as necessary. `<IP:PORT>` should be the IP address and port where headscale is running. In most cases, this will be `http://localhost:8080`.
+
+```Nginx

+```
+
+### Envoy
+
+You need add a new upgrade_type named `tailscale-control-protocol`.

+# Running headscale on OpenBSD
+
+## Goal
+
+This documentation has the goal of showing a user how-to install and run `headscale` on OpenBSD 7.1.
+In additional to the "get up and running section", there is an optional [rc.d section](#running-headscale-in-the-background-with-rcd)
+describing how to make `headscale` run properly in a server environment.
+
+## Install `headscale`
+
+1. Install from ports (Not Recommend)
+
+   As of OpenBSD 7.1, there's a headscale in ports collection, however, it's severely outdated(v0.12.4).
+   You can install it via `pkg_add headscale`.
+
+2. Install from source on OpenBSD 7.1
+
+```shell
+# Install prerequistes
+# 1. go v1.19+: headscale newer than 0.17 needs go 1.19+ to compile
+# 2. gmake: Makefile in the headscale repo is written in GNU make syntax
+pkg_add -D snap go
+pkg_add gmake
+
+git clone https://github.com/juanfont/headscale.git
+
+cd headscale
+
+# optionally checkout a release
+# option a. you can find offical relase at https://github.com/juanfont/headscale/releases/latest
+# option b. get latest tag, this may be a beta release
+latestTag=$(git describe --tags `git rev-list --tags --max-count=1`)
+
+git checkout $latestTag
+
+gmake build
+
+# make it executable
+chmod a+x headscale
+
+# copy it to /usr/local/sbin
+cp headscale /usr/local/sbin
+```
+
+3. Install from source via cross compile
+
+```shell
+# Install prerequistes
+# 1. go v1.19+: headscale newer than 0.17 needs go 1.19+ to compile
+# 2. gmake: Makefile in the headscale repo is written in GNU make syntax
+
+git clone https://github.com/juanfont/headscale.git
+
+cd headscale
+
+# optionally checkout a release
+# option a. you can find offical relase at https://github.com/juanfont/headscale/releases/latest
+# option b. get latest tag, this may be a beta release
+latestTag=$(git describe --tags `git rev-list --tags --max-count=1`)
+
+git checkout $latestTag
+
+make build GOOS=openbsd
+
+# copy headscale to openbsd machine and put it in /usr/local/sbin
+```
+
+## Configure and run `headscale`
+
+1. Prepare a directory to hold `headscale` configuration and the [SQLite](https://www.sqlite.org/) database:
+
+```shell
+# Directory for configuration
+
+mkdir -p /etc/headscale
+
+# Directory for Database, and other variable data (like certificates)
+mkdir -p /var/lib/headscale
+```
+
+2. Create an empty SQLite database:
+
+```shell
+touch /var/lib/headscale/db.sqlite
+```
+
+3. Create a `headscale` configuration:
+
+```shell
+touch /etc/headscale/config.yaml
+```
+
+It is **strongly recommended** to copy and modify the [example configuration](../config-example.yaml)
+from the [headscale repository](../)
+
+4. Start the headscale server:
+
+```shell
+headscale serve
+```
+
+This command will start `headscale` in the current terminal session.
+
+---
+
+To continue the tutorial, open a new terminal and let it run in the background.
+Alternatively use terminal emulators like [tmux](https://github.com/tmux/tmux).
+
+To run `headscale` in the background, please follow the steps in the [rc.d section](#running-headscale-in-the-background-with-rcd) before continuing.
+
+5. Verify `headscale` is running:
+
+Verify `headscale` is available:
+
+```shell
+curl http://127.0.0.1:9090/metrics
+```
+
+6. Create a namespace ([tailnet](https://tailscale.com/kb/1136/tailnet/)):
+
+```shell
+headscale namespaces create myfirstnamespace
+```
+
+### Register a machine (normal login)
+
+On a client machine, execute the `tailscale` login command:
+
+```shell
+tailscale up --login-server YOUR_HEADSCALE_URL
+```
+
+Register the machine:
+
+```shell
+headscale --namespace myfirstnamespace nodes register --key <YOU_+MACHINE_KEY>
+```
+
+### Register machine using a pre authenticated key
+
+Generate a key using the command line:
+
+```shell
+headscale --namespace myfirstnamespace preauthkeys create --reusable --expiration 24h
+```
+
+This will return a pre-authenticated key that can be used to connect a node to `headscale` during the `tailscale` command:
+
+```shell
+tailscale up --login-server <YOUR_HEADSCALE_URL> --authkey <YOUR_AUTH_KEY>
+```
+
+## Running `headscale` in the background with rc.d
+
+This section demonstrates how to run `headscale` as a service in the background with [rc.d](https://man.openbsd.org/rc.d).
+
+1. Create a rc.d service at `/etc/rc.d/headscale` containing:
+
+```shell
+#!/bin/ksh
+
+daemon="/usr/local/sbin/headscale"
+daemon_logger="daemon.info"
+daemon_user="root"
+daemon_flags="serve"
+daemon_timeout=60
+
+. /etc/rc.d/rc.subr
+
+rc_bg=YES
+rc_reload=NO
+
+rc_cmd $1
+```
+
+2. `/etc/rc.d/headscale` needs execute permission:
+
+```shell
+chmod a+x /etc/rc.d/headscale
+```
+
+3. Start `headscale` service:
+
+```shell
+rcctl start headscale
+```
+
+4. Make `headscale` service start at boot:
+
+```shell
+rcctl enable headscale
+```
+
+5. Verify the headscale service:
+
+```shell
+rcctl check headscale
+```
+
+Verify `headscale` is available:
+
+```shell
+curl http://127.0.0.1:9090/metrics
+```
+
+`headscale` will now run in the background and start at boot.

+# Connecting a Windows client
+
+## Goal
+
+This documentation has the goal of showing how a user can use the official Windows [Tailscale](https://tailscale.com) client with `headscale`.
+
+## Add registry keys
+
+To make the Windows client behave as expected and to run well with `headscale`, two registry keys **must** be set:
+
+- `HKLM:\SOFTWARE\Tailscale IPN\UnattendedMode` must be set to `always` as a `string` type, to allow Tailscale to run properly in the background
+- `HKLM:\SOFTWARE\Tailscale IPN\LoginURL` must be set to `<YOUR HEADSCALE URL>` as a `string` type, to ensure Tailscale contacts the correct control server.
+
+![windows-registry](./images/windows-registry.png)
+
+The Tailscale Windows client has been observed to reset its configuration on logout/reboot and these two keys [resolves that issue](https://github.com/tailscale/tailscale/issues/2798).
+
+For a guide on how to edit registry keys, [check out Computer Hope](https://www.computerhope.com/issues/ch001348.htm).
+
+## Installation
+
+Download the [Official Windows Client](https://tailscale.com/download/windows) and install it.
+
+When the installation has finished, start Tailscale and log in (you might have to click the icon in the system tray).
+
+The log in should open a browser Window and direct you to your `headscale` instance.
+
+## Troubleshooting
+
+If you are seeing repeated messages like:
+
+```
+[GIN] 2022/02/10 - 16:39:34 | 200 |    1.105306ms |       127.0.0.1 | POST     "/machine/redacted"
+```
+
+in your `headscale` output, turn on `DEBUG` logging and look for:
+
+```
+2022-02-11T00:59:29Z DBG Machine registration has expired. Sending a authurl to register machine=redacted
+```
+
+This typically means that the registry keys above was not set appropriately.
+
+To reset and try again, it is important to do the following:
+
+1. Ensure the registry keys from the previous guide is correctly set.
+2. Shut down the Tailscale service (or the client running in the tray)
+3. Delete Tailscale Application data folder, located at `C:\Users\<USERNAME>\AppData\Local\Tailscale` and try to connect again.
+4. Ensure the Windows node is deleted from headscale (to ensure fresh setup)
+5. Start Tailscale on the windows machine and retry the login.
