FAQPage Schema

How do I run a read-only health and security audit on an Ubuntu VPS running Docker?▼

To run a read-only health and security audit, SSH into your Ubuntu VPS and execute the command sequence from the Skill's checkup reference file to generate a comprehensive report without applying changes.

Can I check SSHD, UFW, and Fail2ban configurations without modifying my production server?▼

Yes, you can check SSHD, UFW, and Fail2ban configurations safely because the review is strictly read-only, analyzing your security posture and outputting recommendations without applying system modifications.

What is the best way to get a Docker health overview including container status and disk usage?▼

The best way to get a Docker health overview is using an automated checkup that reviews daemon status, running containers, disk usage, and Compose projects to produce a prioritized baseline report.

Does the VPS security review automatically apply fixes to SSHD or Docker configurations?▼

No, the VPS security review does not automatically apply fixes; it provides minimal actionable recommendations and only executes safe changes after you provide explicit confirmation during the audit workflow.

When do I need to generate a read-only VPS health report?▼

You need to generate a read-only VPS health report when you want a trusted baseline before applying system updates, or prior to making configuration changes in a production Docker environment.

Can I use this Docker checkup on a Linux distribution other than Ubuntu?▼

The checkup is specifically designed for an Ubuntu VPS running Docker, targeting Ubuntu-specific security and Docker health checks, so compatibility with other Linux distributions is not guaranteed.
