Practice Verified Codes and Commands:
1. Linux Command to Monitor Network Traffic:
sudo tcpdump -i eth0 -w capture.pcap
This command captures network traffic on the `eth0` interface and saves it to a file named `capture.pcap` for analysis.
2. Windows Command to Check Open Ports:
Test-NetConnection -ComputerName 192.168.1.1 -Port 80
This PowerShell command checks if port 80 is open on the specified IP address.
3. Python Script for Basic Port Scanner:
import socket
target = "192.168.1.1"
ports = [21, 22, 80, 443]
for port in ports:
sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.settimeout(1)
result = sock.connect_ex((target, port))
if result == 0:
print(f"Port {port} is open")
sock.close()
This script scans common ports on a target IP address to check for open ports.
4. Bash Script for Log Analysis:
grep "ERROR" /var/log/syslog | awk '{print $1, $2, $3, $6}' > error_logs.txt
This script extracts lines containing “ERROR” from the system log and saves them to a file for further analysis.
