## BBS / SSH access
To enable simple command line interface accessible over ssh, add a setting like this to your configuration file:
```exs
app_dir = File.cwd!
priv_dir = Path.join([app_dir, "priv/ssh_keys"])
config :esshd,
enabled: true,
priv_dir: priv_dir,
handler: "Pleroma.BBS.Handler",
port: 10_022,
password_authenticator: "Pleroma.BBS.Authenticator"
```
Feel free to adjust the priv_dir and port number. Then you will have to create the key for the keys (in the example `priv/ssh_keys`) and create the host keys with `ssh-keygen -N "" -b 2048 -t rsa -f ssh_host_rsa_key`. After restarting, you should be able to connect to your Pleroma instance with `ssh username@server -p $PORT`
## :auth
* `Pleroma.Web.Auth.PleromaAuthenticator`: default database authenticator
* `Pleroma.Web.Auth.LDAPAuthenticator`: LDAP authentication
Authentication / authorization settings.
* `auth_template`: authentication form template. By default it's `show.html` which corresponds to `lib/pleroma/web/templates/o_auth/o_auth/show.html.eex`.
