hping3 is a command-line tool used to test network and host security. It sends customized packets to a target host and analyzes the responses to detect potential vulnerabilities. This tool can be used to test firewalls, intrusion detection systems, and network performance.
hping3 is a versatile tool that can be used for both offensive and defensive purposes.
hping3 command has a wide range of options, making it a powerful tool for network security testing. The basic syntax of the command is as follows:
hping3 [options] target
target can be an IP address, hostname, or network range. Here are some common use cases for
- Ping sweep:
hping3can be used to perform a ping sweep of a network range to identify active hosts. For example:
hping3 -1 -c 10 -i 1 192.168.0.0/24
This command sends 10 ICMP echo requests (
-c 10) with an interval of 1 second (
-i 1) to all hosts in the
- TCP SYN scan:
hping3can be used to perform a TCP SYN scan to identify open ports on a target host. For example:
hping3 -S -p 80 target.com
This command sends a TCP SYN packet to port 80 (
-p 80) of
target.com. If the port is open, the target will respond with a SYN-ACK packet.
- Firewall testing:
hping3can be used to test firewall rules by sending packets with different flags and payloads. For example:
hping3 -F -p 80 target.com
This command sends a FIN packet to port 80 (
-p 80) of
target.com. If the firewall is blocking FIN packets, the target will not respond.
Here are the available options for the
||Set the number of packets to send.|
||Set the interval between packets.|
||Do not resolve hostnames.|
||Set the destination port.|
||Send a TCP SYN packet.|
||Send a TCP FIN packet.|
||Send a UDP packet.|
||Send an ICMP echo request.|
||Print verbose output.|
- If you are not receiving any responses from the target host, make sure that the host is online and that there are no firewall rules blocking the packets.
- If you are getting unexpected results, double-check your command syntax and options.
- If you are testing a production network, make sure to get permission from the network administrator before running
