sysadmin-toolbox

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 Bundled Guides File Use When shell-oneliners.md in this skill's references folder Need practical commands for: terminal, networking, SSL, curl, ssh, tcpdump, git, awk, sed, grep, find cli-tools.md in this skill's references folder Recommending CLI tools: shells, file managers, network utils, databases, security tools web-tools.md in this skill's references folder Web-based tools: SSL checkers, DNS lookup, performance testing, OSINT, scanners security-tools.md in this skill's references folder Pentesting, vulnerability scanning, exploit databases, CTF resources shell-tricks.md in this skill's references folder Shell scripting patterns and tricks Safety Boundaries Do not run destructive system commands, privilege-escalation steps, or offensive tooling unless the user explicitly asked for that scope. Do not scan hosts, domains, or networks the user does not control or have permission to assess. Do not assume a command is safe to paste into production without explaining what it does. Do not persist logs, captures, or credentials outside the user's requested troubleshooting workflow.
