Sysadmin Toolbox
Curated tool recommendations and practical shell one-liners for operational work.
When to Auto-Consult
Load relevant references when user is:
- Debugging network connectivity, ports, traffic
- Troubleshooting DNS or SSL/TLS
- Analyzing processes, memory, disk usage
- Working with logs or system diagnostics
- Writing shell scripts or one-liners
- Asking "what's a good tool for..."
- Doing security audits or pentesting
- Working with containers/Docker/K8s

Example Queries → Actions
"Why is this port not responding?" → Load shell-oneliners.md, search for netstat/ss/lsof commands
"What's a good tool for testing SSL?" → Load cli-tools.md SSL section, recommend testssl.sh or sslyze
"Show me how to find large files" → Load shell-oneliners.md, search for find/ncdu/du commands
"I need to debug DNS resolution" → Load shell-oneliners.md dig section + recommend dnsdiag from cli-tools.md
