SSH Attacks in Real Time | tcpdump Packet Analysis

See SSH brute force attacks in real time — safely on your own Ubuntu machine, with no external server required.

In this beginner-friendly Linux and cybersecurity tutorial, you’ll learn how to use tcpdump to monitor SSH connection attempts and understand what a brute-force attack looks like at the network level.

Instead of attacking a real system, we simulate everything locally using localhost, making this a safe and practical lab for learning network security and packet analysis.

What You’ll Learn
How to detect SSH brute force attacks using tcpdump
How TCP SYN packets indicate connection attempts
How to monitor traffic on port 22 (SSH)
How to simulate brute-force attempts safely on one machine
How to read and understand tcpdump output (IP, ports, flags, sequence, window size).

Commands Used in This Video
sudo tcpdump -i lo 'tcp[tcpflags] & tcp-syn != 0 and dst port 22'
ssh localhost

Who This Is For
Beginners in cybersecurity / ethical hacking
Linux users learning network monitoring
DevOps engineers exploring tcpdump and packet capture
Anyone curious about how brute-force attacks actually look

⚠️ Important Note
This is a safe simulation for educational purposes only. Do not attempt unauthorized access to systems — it may be illegal.
