HPING3 in Kali Linux

HPING3 is a command-line network tool used for crafting and analyzing network packets. It is an essential tool for penetration testers, ethical hackers, and network administrators to diagnose network issues, test firewalls, and conduct security assessments.

HPING3 allows users to send custom TCP/IP packets to a target, making it a powerful tool for network scanning, port scanning, and stress testing.

Install HPING3

HPING3 is usually pre-installed in Kali Linux. If it is not available, install it using:

$ sudo apt-get install hping3

Syntax

The basic syntax of HPING3 is:

$ hping3 [options]

Examples

Ping a Host Using TCP

To send a TCP SYN packet to a target on port 80, use:

hping3 -S -p 80 example.com

ICMP Ping Like Traditional Ping

To send ICMP Echo requests like the traditional ping command:

hping3 -1 example.com

UDP Scan on a Specific Port

To check if UDP port 53 (DNS) is open on a target:

hping3 --udp -p 53 example.com

Perform a Traceroute

To trace the route to a target:

hping3 --traceroute example.com

The output of HPING3 will show details such as:

• Response time of packets
• Open or closed status of ports
• Firewall responses and packet filtering behaviors

Limitations of HPING3

While HPING3 is a powerful tool, it has some limitations:

• Requires root privileges for certain operations
• May be blocked by firewalls or IDS/IPS systems
• Misuse can lead to detection by security teams

HPING3 is an essential tool for network security testing, packet crafting, and performance analysis. It provides advanced control over network packets, making it a valuable addition to any security toolkit.
