Server down, service won't start, disk full, something is slow
and you don't know why? I will find the cause and fix it.
Typical problems I fix
- Service won't start or keeps crashing (systemd, Docker)
- Disk full, high CPU or memory usage
- Network issues: ports, firewall, DNS, connectivity
- SSH access problems
- Permission and user errors
- Errors after updates or config changes
How it works
1. You describe the problem
2. I diagnose: logs, processes, network, configs
3. I fix it, or tell you exactly what is needed if it
requires something outside the server
4. You get a short report: what was wrong, what I changed,
and how to avoid it next time
What I need from you
- Description of the problem and when it started
- SSH access (I will send you my public key, no passwords)
Safety first
- Snapshot/backup before any change
- No changes without explaining them first
