Network Tools

A solid reference for Linux network diagnostics that covers the essentials without fluff. You get quick lookups for ss, netstat, tcpdump, and curl with practical filters and flags you'll actually use. The troubleshooting scenarios are helpful, like checking what's hogging port 8080 or testing HTTP service health with timing info. It leans modern where it matters (ss over netstat, ip over ifconfig) but includes legacy commands since you'll encounter both. Nothing groundbreaking here, just a well-organized cheat sheet that saves you from googling tcpdump syntax for the hundredth time. Good for both debugging production issues and general network exploration.

Connectivity Testing

ping

ping hostname
ping -c 4 hostname                  # Send 4 packets
ping -i 0.2 hostname                # 0.2 second interval
ping -s 1000 hostname               # Specify packet size

traceroute

traceroute hostname
traceroute -n hostname              # Don't resolve hostnames
traceroute -T hostname              # Use TCP
mtr hostname                        # Real-time trace
