.B \-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).
|
|
|
|
|
.TP
|
|
|
|
|
.B \-2
|
|
|
|
|
Run IP test group #2. This group of tests generates packets with the IP
|
|
|
|
|
options constructed with invalud values given other packet characteristics.
|
|
|
|
|
The point tests are: 1 (option length > packet length), 2 (option length = 0).
|
|
|
|
|
.TP
|
|
|
|
|
.B \-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).
|
|
|
|
|
.TP
|
|
|
|
|
.B \-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)).
|
|
|
|
|
.TP
|
|
|
|
|
.B \-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).
|
|
|
|
|
.TP
|
|
|
|
|
.B \-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
|
|
|
|
|
reassembly. WARNING: this may crash or cause serious performance degradation
|
|
|
|
|
to the target host.
|
|
|
|
|
.TP
|
|
|
|
|
.B \-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.
|
|
|
|
|
.TP
|
|
|
|
|
.BR \-d \0<interface>
|
|
|
|
|
Set the interface name to be the name supplied.
|
|
|
|
|
.TP
|
|
|
|
|
.BR \-g \0<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.
|
|
|
|
|
.TP
|
|
|
|
|
.BR \-m \0<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.
