Скачать или смотреть FTP vs SCP Showdown: Secure File Transfer + Linux Networking Crash Course (Hands-On Lab!)

🔌 Master Linux Networking: ping, curl, netstat, ss, FTP & SCP - Real-World Labs

🚀 Why This Matters:
90% of network troubleshooting uses these 6 commands (2024 Dice Report). I use these daily as a cloud engineer!

💻 Today’s Hands-On Labs:
✔ Connectivity Testing:
`ping -c 4 google.com` (Controlled pings)
`curl -I example.com` (Check website headers)

✔ Port Investigation:
Legacy: `netstat -tulnp` (Find listening services)
Modern: `ss -tunp` (Faster socket analysis)

✔ File Transfer Wars:
FTP Lab: Linux ↔ Linux & Linux ↔ Windows transfers (With security warnings)
SCP Lab: Encrypted Linux ↔ Linux transfers (`scp -P 22 -r /local user@remote:/path`)

🔥 Pro Tip: Always use `scp -C` for compression on slow networks!
