# Setting up Buscarron (optional)
The playbook can install and configure [Buscarron](https://github.com/etkecc/buscarron) for you.
2022-04-23 13:19:24 +00:00
Buscarron is bot that receives HTTP POST submissions of web forms and forwards them to a Matrix room.
2022-04-23 13:19:24 +00:00
## Adjusting the playbook configuration
To enable Buscarron, add the following configuration to your `inventory/host_vars/matrix.example.com/vars.yml` file:
2022-04-23 13:19:24 +00:00
```yaml
matrix_bot_buscarron_enabled: true
# Uncomment and adjust this part if you'd like to use a username different than the default
# matrix_bot_buscarron_login: bot.buscarron
# Generate a strong password here. Consider generating it with `pwgen -s 64 1`
2022-04-23 13:19:24 +00:00
matrix_bot_buscarron_password: PASSWORD_FOR_THE_BOT
# Adjust accepted forms
matrix_bot_buscarron_forms:
- name: contact # (mandatory) Your form name, will be used as endpoint, eg: buscarron.example.com/contact
room: "!qporfwt:{{ matrix_domain }}" # (mandatory) Room ID where form submission will be posted
redirect: https://example.com # (mandatory) To what page user will be redirected after the form submission
2022-04-25 06:40:49 +00:00
ratelimit: 1r/m # (optional) rate limit of the form, format: <max requests>r/<interval:s,m>, eg: 1r/s or 54r/m
2022-10-25 15:39:39 +00:00
hasemail: 1 # (optional) form has "email" field that should be validated
2022-04-25 06:40:49 +00:00
extensions: [] # (optional) list of form extensions (not used yet)
2022-04-23 13:19:24 +00:00
2022-10-25 15:39:39 +00:00
matrix_bot_buscarron_spamlist: [] # (optional) list of emails/domains/hosts (with wildcards support) that should be rejected automatically
2022-04-23 13:19:24 +00:00
```
### Adjusting the Buscarron URL
By default, this playbook installs Buscarron on the `buscarron.` subdomain (`buscarron.example.com`) and requires you to [adjust your DNS records](#adjusting-dns-records).
By tweaking the `matrix_bot_buscarron_hostname` and `matrix_bot_buscarron_path_prefix` variables, you can easily make the service available at a **different hostname and/or path** than the default one.
Example additional configuration for your `inventory/host_vars/matrix.example.com/vars.yml` file:
```yaml
# Switch to the domain used for Matrix services (`matrix.example.com`),
# so we won't need to add additional DNS records for Buscarron.
matrix_bot_buscarron_hostname: "{{ matrix_server_fqn_matrix }}"
# Expose under the /buscarron subpath
matrix_bot_buscarron_path_prefix: /buscarron
```
## Adjusting DNS records
Once you've decided on the domain and path, **you may need to adjust your DNS** records to point the Buscarron domain to the Matrix server.
By default, you will need to create a CNAME record for `buscarron`. See [Configuring DNS](configuring-dns.md) for details about DNS changes.
If you've decided to reuse the `matrix.` domain, you won't need to do any extra DNS configuration.

- The `ensure-matrix-users-created` playbook tag makes the playbook automatically create the bot's user account.
- The shortcut commands with the [`just` program](just.md) are also available: `just install-all` or `just setup-all`
2022-04-23 13:19:24 +00:00
`just install-all` is useful for maintaining your setup quickly when its components remain unchanged. If you adjust your `vars.yml` to remove other components, you'd need to run `just setup-all`, or these components will still remain installed.

- If you change the bot password (`matrix_bot_buscarron_password` in your `vars.yml` file) subsequently, the bot user's credentials on the homeserver won't be updated automatically. If you'd like to change the bot user's password, use a tool like [synapse-admin](configuring-playbook-synapse-admin.md) to change it, and then update `matrix_bot_buscarron_password` to let the bot know its new password.
2022-04-23 13:19:24 +00:00
## Usage
To use the bot, invite the `@bot.buscarron:example.com` to the room you specified in a config, after that any point your form to the form url, example for the `contact` form:
2022-04-23 13:19:24 +00:00
```html
<form method="POST" action="https://buscarron.example.com/contact">
2022-04-23 13:19:24 +00:00
<!--your fields-->
</form>
```
**Note**: to fight against spam, Buscarron is **very aggressive when it comes to banning** and will ban you if:
- if you hit the homepage (HTTP `GET` request to `/`)
- if you submit a form to the wrong URL (`POST` request to `/non-existing-form`)
- if `hasemail` is enabled for the form (like in the example above) and you don't submit an `email` field
If you get banned, you'd need to restart the process by running the playbook with `--tags=start` or running `systemctl restart matrix-bot-buscarron` on the server.
You can also refer to the upstream [documentation](https://github.com/etkecc/buscarron).
