How do I run a health and security checkup on my Ubuntu VPS?▼

Run a health and security checkup to analyze your Ubuntu VPS by gathering read-only data on system resources, SSH configuration, UFW, Fail2ban, and Docker status. The process identifies potential issues and proposes safe fixes without making system changes.

Can I check my Docker container status and system updates without modifying the VPS?▼

Yes, you can check Docker container status and system updates in a read-only mode. The analysis assesses Docker daemon health, container resource usage, and available package updates, proposing fixes that are only applied after explicit confirmation.

Does this VPS checkup work with Fail2ban and UFW firewall configurations?▼

Yes, this VPS checkup works with Fail2ban and UFW by analyzing your security posture. It checks your active UFW firewall status and Fail2ban jails to identify configuration issues and suggest safe security fixes.

What is the best way to identify available package updates and required reboots on Ubuntu?▼

The best way to identify updates is through a read-only system report that checks available package updates and flags if a reboot is required. This ensures you see pending updates safely before applying them.

How does applying updates and restarting services work during a VPS health check?▼

Applying updates and restarting services works by first generating a read-only report of required fixes. The system strictly waits for your explicit user confirmation before applying any package updates or restarting system services.

When should I avoid using an automated VPS security and update report?▼

You should avoid using an automated VPS security report if your server does not run Ubuntu or Docker. The analysis specifically targets Ubuntu VPS environments running Docker to assess system services, SSH, and container health.
