If your WFH desk setup doesn't cost more than a used Honda Civic, you aren't serious about your pipeline.

My ergonomic chair is built from the salvaged suspension of a 2019 Tesla Model S.

My primary monitor is a converted IMAX screen I bought from a bankrupt theater in Oakland.

When I drag a cell in Google Sheets, I physically have to rotate my entire torso. I burn 400 active calories a day just searching for the Slack icon.

Stop complaining about back pain and optimize your environment.

Parabéns aos envolvidos: agora até as distros Linux estão bloqueando o Brasil. Nem vou falar dos outros serviços que a galera já está descobrindo da pior forma.

Nmap Commands for Educational Use only.

Nmap is a network scanning tool used by system administrators, IT professionals, and students for security auditing, troubleshooting, and learning.

Common Scans

nmap -sP → Ping Scan: Checks which devices are active on a network.

nmap -sS → TCP SYN Scan: Helps discover open services.

nmap -sU → UDP Scan: Finds active UDP services.

nmap -sV → Version Detection: Identifies service versions for maintenance.

nmap -O → OS Detection: Detects operating system type (for compatibility testing).

nmap -A → Aggressive Scan: Runs multiple checks for detailed results.

Timing & Input

nmap -T4 → Timing Template: Controls scan speed.

nmap -iL → Input from List: Reads targets from a file (useful for admins).

nmap -sn → Host Discovery: Finds devices without scanning ports.

Advanced TCP Techniques

nmap -sX → XMAS Scan: Uses a special test packet to check responses.

nmap -sF → FIN Scan: Uses a different method for host analysis.

nmap -sT → TCP Connect Scan: Connects directly to services.

nmap -sN → Null Scan: Uses empty packets to analyze responses.

nmap -sA → ACK Scan: Helps detect firewall filtering.

Scripting & Port Options

nmap -sC → Default Script Scan: Runs safe built-in scripts.

nmap --script <script> → Run Specific Script: For detailed service checks.

nmap --top-ports <number> → Top Ports Scan: Scans the most used ports.

Note:
These commands are meant for learning, ethical security research, and network administration only. Always use Nmap on your own systems or with proper authorization.
