# 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 ## Reference Files | File | Use When | |------|----------| | `references/shell-oneliners.md` | Need practical commands for: terminal, networking, SSL, curl, ssh, tcpdump, git, awk, sed, grep, find | | `references/cli-tools.md` | Recommending CLI tools: shells, file managers, network utils, databases, security tools | | `references/web-tools.md` | Web-based tools: SSL checkers, DNS lookup, performance testing, OSINT, scanners | | `references/security-tools.md` | Pentesting, vulnerability scanning, exploit databases, CTF resources | | `references/shell-tricks.md` | Shell scripting patterns and tricks | ## Quick Tool Index ### Network Debugging - `mtr` - traceroute + ping combined - `tcpdump` / `tshark` - packet capture - `netstat` / `ss` - connection monitoring - `nmap` - port scanning - `curl` / `httpie` - HTTP testing ### DNS - `dig` / `host` - DNS queries - `dnsdiag` - DNS diagnostics - `subfinder` / `amass` - subdomain enumeration ### SSL/TLS - `openssl` - certificate inspection - `testssl.sh` - TLS testing - `sslyze` - SSL scanning - `certbot` - Let's Encrypt ### Process/System - `htop` / `btop` - process monitoring - `strace` / `ltrace` - syscall/library tracing - `lsof` - open files/connections - `ncdu` - disk usage ### Log Analysis - `lnav` - log navigator - `GoAccess` - web log analyzer - `angle-grinder` - log slicing ### Containers - `dive` - Docker image analysis - `ctop` - container top - `lazydocker` - Docker TUI ## Keeping Current References auto-refresh weekly (Sundays 5am ET) from the upstream repo: ```bash ~/clawd-duke-leto/skills/sysadmin-toolbox/scripts/refresh.sh ``` Manual refresh anytime: ```bash ./scripts/refresh.sh [skill-dir] ``` ## 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
