# Frequently Asked Questions

#### **Question: How can I test if open-appsec detects/prevents attacks correctly after enabling it for one of my proxy host objects in NGINX Proxy Manager?**

You can append the following to your http(s) requests to simulate an attack which should be detected/prevented by open-appsec:\
`?shell_cmd=cat/etc/passwd`

Example: `http://localhost/?shell_cmd=cat/etc/passwd`

***

#### **Question: How can I check the status of my open-appsec agent?**

You can run the command `open-appsec-ctl -s` inside the appsec-agent container:\
`docker exec appsec-agent open-appsec-ctl -s`\
\
Status should be “running” for all services in the list and "Policy load status" should show "Success".\
\
Note that the Http Transaction Handler Nano Service will only switch from “ready” to “running” state after it has received some initial packets from the attachment integrated with NPM's included NGINX reverse proxy.\

Here’s an example output:
