Exploring networking protocols is fundamental for cybersecurity professionals. The “Networking Essentials” room on TryHackMe covers automatic configuration, routing, and packet delivery—critical skills for SOC analysts and network defenders.
You Should Know:
Key Networking Commands & Tools
Linux Networking Commands
1. `ifconfig` / `ip addr` – View and configure network interfaces.
ip addr show eth0
2. `netstat` – Display active connections and listening ports.
netstat -tuln
3. `traceroute` / `tracepath` – Trace the path packets take to a destination.
traceroute google.com
4. `nmap` – Network scanning for open ports and services.
nmap -sV 192.168.1.1
5. `tcpdump` – Capture and analyze network traffic.
tcpdump -i eth0 -n 'tcp port 80'
Windows Networking Commands
1. `ipconfig` – Display IP configuration.
ipconfig /all
2. `netstat` – Check active connections.
netstat -ano
3. `tracert` – Trace route to a host.
tracert google.com
4. `nslookup` – Query DNS records.
nslookup tryhackme.com
Hands-On Practice with TryHackMe
TryHackMe’s Networking Essentials room includes practical exercises on:
- DHCP & IP Addressing – Use `dhclient` to request an IP.
sudo dhclient eth0
- Subnetting – Calculate subnets using
ipcalc.ipcalc 192.168.1.0/24
- Firewall Rules – Configure `iptables` to filter traffic.
sudo iptables -A INPUT -p tcp --dport 22 -j ACCEPT
