Network Scanning
hping3
Craft custom TCP/UDP/ICMP packets for firewall and stack testing.
Authorized testing only. Practice on systems you own, isolated labs, or targets with written permission. Unauthorized access is illegal.
Flood modes can disrupt services — lab only / explicit permission.
When
Testing firewall rules, idle scans, or path behavior under authorization.
How
Craft SYN/ACK/FIN probes; observe responses; document filtering behavior.
Why
Teaches how packets actually behave beyond automated scanners.
Commands & usage
sudo hping3 -S -p 80 -c 3 192.168.1.10
sudo hping3 --flood --rand-source -p 80 192.168.1.10
Commands are educational examples. Adapt hosts, paths, and rates to your authorized scope.
