hping3 – Network Analyser & Pen Tester Tool


hping3 is a network tool command able to send custom TCP/IP packets and to echo requests like ping command does with ICMP requests. hping3 command handles fragmentation, and almost arbitrary packet body & size and and can be used to share files using supported protocols. And the protocol it supports are TCP, UDP, ICMP and RAW-IP protocols.

Since version 3, hping uses scripting capabilties, open the API.txt file from the /docs directory (folder) to know more about it.

Previously, hping was mainly used as Assembler & Analyser, but it can be used in different ways for security purpose to scan networks and hosts.

hping is useful to test many types of networking devices like firewalls, routers and others.It uses Tcl language to test security scanning. It can be used for:

  • Firewall testing.
  • Advanced port scanning.
  • Network testing, using different protocols, TOS, fragmentation.
  • Networking research.
  • Write real applications related to TCP/IP testing and security.
  • Manual path MTU discovery.
  • Advanced traceroute, under all the supported protocols.
  • Remote OS fingerprinting.
  • Remote uptime guessing.
  • TCP/IP stacks auditing.
  • Prototype IDS systems.
  • Perform the idle scan.

hping3 is developed and manteined by Salvatore Sanfilippo (antirez@invece.org) with the help of other co-developers, and licensed under GPL version 2.

hping runs on the unix-like systems such as: Linux, FreeBSD, NetBSD, OpenBSD, Solaris, MacOs X, Windows.

Tools involved in the hping3 package:

-i  –interval  wait (uX for X microseconds, for example -i u1000)
–fast      alias for -i u10000 (10 packets for second)
–faster    alias for -i u1000 (100 packets for second)
–flood      sent packets as fast as possible. Don’t show replies.
-n  –numeric   numeric output
-q  –quiet     quiet
-I  –interface interface name (otherwise default routing interface)
-V  –verbose   verbose mode
-D  –debug     debugging info
-z  –bind      bind ctrl+z to ttl           (default to dst port)
-Z  –unbind    unbind ctrl+z
–beep      beep for every matching packet received
default mode     TCP
-0  –rawip      RAW IP mode
-1  –icmp       ICMP mode
-2  –udp        UDP mode
-8  –scan       SCAN mode.
Example: hping –scan 1-30,70-90 -S www.target.host
-9  –listen     listen mode
-a  –spoof      spoof source address
–rand-dest      random destionation address mode. see the man.
–rand-source    random source address mode. see the man.
-t  –ttl        ttl (default 64)
-N  –id         id (default random)
-W  –winid      use win* id byte ordering
-r  –rel        relativize id field          (to estimate host traffic)
-f  –frag       split packets in more frag.  (may pass weak acl)
-x  –morefrag   set more fragments flag
-y  –dontfrag   set don’t fragment flag
-g  –fragoff    set the fragment offset
-m  –mtu        set virtual mtu, implies –frag if packet size > mtu
-o  –tos        type of service (default 0x00), try –tos help
-G  –rroute     includes RECORD_ROUTE option and display the route buffer
–lsrr           loose source routing and record route
–ssrr           strict source routing and record route
-H  –ipproto    set the IP protocol field, only in RAW IP mode
-C  –icmptype   icmp type (default echo request)
-K  –icmpcode   icmp code (default 0)
–force-icmp send all icmp types (default send only supported types)
–icmp-gw    set gateway address for ICMP redirect (default
–icmp-ts    Alias for –icmp –icmptype 13 (ICMP timestamp)
–icmp-addr  Alias for –icmp –icmptype 17 (ICMP address subnet mask)
–icmp-help  display help for others icmp options
-s  –baseport   base source port             (default random)
-p  –destport   [+][+]<port> destination port(default 0) ctrl+z inc/dec
-k  –keep       keep still source port
-w  –win        winsize (default 64)
-O  –tcpoff     set fake tcp data offset     (instead of tcphdrlen / 4)
-Q  –seqnum     shows only tcp sequence number
-b  –badcksum   (try to) send packets with a bad IP checksum
many systems will fix the IP checksum sending the packet
so you’ll get bad UDP/TCP checksum instead.
-M  –setseq     set TCP sequence number
-L  –setack     set TCP ack
-F  –fin        set FIN flag
-S  –syn        set SYN flag
-R  –rst        set RST flag
-P  –push       set PUSH flag
-A  –ack        set ACK flag
-U  –urg        set URG flag
-X  –xmas       set X unused flag (0x40)
-Y  –ymas       set Y unused flag (0x80)
–tcpexitcode    use last tcp->th_flags as exit code
–tcp-mss        enable the TCP MSS option with the given value
–tcp-timestamp  enable the TCP timestamp option to guess the HZ/uptime
-d  –data       data size                    (default is 0)
-E  –file       data from file
-e  –sign       add ‘signature’
-j  –dump       dump packets in hex
-J  –print      dump printable characters

–tr-keep-ttl    Keep the source TTL fixed, useful to monitor just one hop
–tr-no-rtt       Don’t calculate/show RTT information in traceroute mode
ARS packet description (new, unstable)
–apd-send       Send the packet described with APD (see docs/APD.txt)
