Fix server problems with confidence.

Break a Docker restart loop by inspecting container state, exit codes, logs, health checks, configuration, and resource limits.

Resolve Docker socket, bind-mount, and container filesystem permission errors without weakening host security.

Find the container or host process occupying a published Docker port and resolve the conflict without disrupting the wrong service.

Find why a Kubernetes container repeatedly crashes by checking pod events, previous logs, exit codes, probes, configuration, and resource limits.

Identify the process listening on a Linux port, distinguish expected services from stale processes, and resolve port conflicts safely.

Determine whether a Linux server ran out of disk blocks or inodes, find the real space consumers, and recover capacity safely.

Use systemctl, journalctl, unit validation, and dependency checks to find why a Linux systemd service failed to start.

Find out why an SSH server refuses connections by checking the port, service status, firewall rules, bind address, and network path.

Resolve SSH host key verification failures safely by checking whether a server was rebuilt, its address changed, or the connection may be intercepted.
