Bouncers

CrowdSec is composed of different components that communicate via a Local API. To access this API, the various components (CrowdSec agent, cscli and bouncers) need to be authenticated.

info

This documentation should be relevant mostly for administrators that would like to setup distributed architectures. Single machine setup users can likely skip this part.

There are two kind of access to the local api :

machines: a login/password authentication used by cscli and CrowdSec, it allows to post, get and delete decisions and alerts.
bouncers: a token authentication used by bouncers to query the decisions, it only allows to get decisions.

caution

The cscli bouncers command interacts directly with the database (bouncers add and delete are not implemented in the API), therefore it must have the correct database configuration.

sudo cscli bouncers list

You can view the registered bouncers with list, and add or delete them :

sudo cscli bouncers add mybouncersname
Api key for 'mybouncersname':

   23........b5a0c

Please keep this key since will not be able to retrieve it!
sudo cscli bouncers delete mybouncersname

The API key must be kept and given to the bouncer configuration.

cscli bouncers example

sudo cscli bouncers add mybouncersname
Api key for 'mybouncersname':

   23........b5a0c

Please keep this key since will not be able to retrieve it!
sudo cscli bouncers list
