NAME
       iptest - automatically generate packets to test IP functionality

SYNOPSIS
       iptest  [ -1234567 ] [ -d <device> ] [ -g <gateway> ] [ -m <MTU> ] [ -p <pointtest> ] [ -s
       <source> ] <destination>

DESCRIPTION
       iptest ...

OPTIONS
       -1     Run IP test group #1.  This group of tests generates packets  with  the  IP  header
	      fields  set  to invalid values given other packet characteristics.  The point tests
	      are: 1 (ip_hl < ip_len), 2 (ip_hl > ip_len), 3 (ip_v < 4), 4 (ip_v > 4), 5  (ip_len
	      <  packetsize,  long  packets),  6  (ip_len  > packet size, short packets), 7 (Zero
	      length fragments), 8 (packet > 64k after reassembly), 9 (IP offset with  MSB  set),
	      10 (ttl variations).

       -2     Run  IP  test  group #2.	This group of tests generates packets with the IP options
	      constructed with invalid values given  other  packet  characteristics.   The  point
	      tests are: 1 (option length > packet length), 2 (option length = 0).

       -3     Run  IP  test group #3.  This group of tests generates packets with the ICMP header
	      fields set to non-standard values.  The point tests are: 1 (ICMP types 0-31 & 255),
	      2  (type	3 & code 0 - 31), 3 (type 4 & code 0, 127, 128, 255), 4 (type 5 & code 0,
	      127, 128, 255), 5 (types 8-10,13-18 with codes 0, 127, 128 and 255), 6 (type  12	&
	      code 0, 127, 128, 129, 255) and 7 (type 3 & codes 9-10, 13-14 and 17-18 - shortened
	      packets).

       -4     Run IP test group #4.  This group of tests generates packets with  the  UDP  header
	      fields  set  to  non-standard  values.  The point tests are: 1 (UDP length > packet
	      size), 2 (UDP length < packetsize), 3 (sport = 0, 1, 32767, 32768, 65535), 4 (dport
	      =  0,  1,  32767,  32768,  65535)  and 5 (sizeof(struct ip) <= MTU <= sizeof(struct
	      udphdr) + sizeof(struct ip)).

       -5     Run IP test group #5.  This group of tests generates packets with  the  TCP  header
	      fields  set  to non-standard values.  The point tests are: 1 (TCP flags variations,
	      all combinations), 2 (seq = 0, 0x7fffffff, 0x8000000, 0xa0000000,  0xffffffff),	3
	      (ack = 0, 0x7fffffff, 0x8000000, 0xa0000000, 0xffffffff), 4 (SYN packet with window
	      of 0, 32768, 65535), 5 (set urgent pointer to 1, 0x7fff, 0x8000, 0xffff),  6  (data
	      offset),	7  (sport = 0, 1, 32767, 32768, 65535) and 8 (dport = 0, 1, 32767, 32768,
	      65535).

       -6     Run IP test group #6.  This test generates  a  large  number  of	fragments  in  an
	      attempt  to exhaust the network buffers used for holding packets for later reassem-
	      bly.  WARNING: this may crash or cause serious performance degradation to the  tar-
	      get host.

       -7     Run  IP test group #7.  This test generates 1024 random IP packets with only the IP
	      version, checksum, length and IP offset field correct.

       -d <interface>
	      Set the interface name to be the name supplied.

       -g <gateway>
	      Specify the hostname of the gateway  through  which  to  route  packets.	 This  is
	      required	whenever the destination host isn't directly attached to the same network
	      as the host from which you're sending.

       -m <MTU>
	      Specify the MTU to be used when sending out packets.  This option allows you to set
	      a  fake MTU, allowing the simulation of network interfaces with small MTU's without
	      setting them so.

       -p <test>
	      Run a...

DIAGNOSTICS
       Only one of the numeric test options may be given when iptest is run.

       Needs to be run as root.
