The SysAdmin Toolkit is a centralized repository of standardized scripts, configuration baselines, operational runbooks, and documentation templates. It is designed to establish a consistent, rigorous engineering discipline across IT infrastructure operations.
This toolkit serves as a portable "Swiss Army Knife" for Systems Administrators, Site Reliability Engineers (SREs), and Network Engineers, providing immediate access to validated tools for diagnostics, security hardening, and crisis management.
Automated scripts for diagnostics, auditing, and maintenance tasks.
system_health_check.sh: (Linux) Generates an instant snapshot of CPU, RAM, Disk, and Failed Services.system-info-collector.bat: (Windows) "Drop-and-run" health report for Windows Servers.network-reset.bat: (Windows) Automated utility to reset Winsock, TCP/IP stack, and flush DNS.log-parser.ps1: (PowerShell) Regex-based log analysis tool for identifying error patterns and frequencies.bulk-rename.ps1: (PowerShell) Mass file sanitization utility for data migrations and standardization.
The knowledge base for Standard Operating Procedures (SOPs) and Policies.
/troubleshooting: SOPs for high-volume operational issues (VoIP, Active Directory, Printers, Network)./best-practices: Definitive policy documents (Password Policy, Backup Strategy, Security Hardening Standards)./servers: Repository for detailed, per-host documentation.
Playbooks for high-stress scenarios and routine maintenance.
critical-incident-response.md: SEV-1 Incident Command structure and workflow.disaster-recovery.md: Protocols for catastrophic site failure, ransomware response, and "Clean Room" recovery.server-maintenance.md: Checklist for routine patching ("Patch Tuesday") and system hygiene.
Reference configurations for security and infrastructure baselines.

Standardized forms to ensure consistency in documentation.
