I needed a way to create realistic TCP PCAP files from text
files,
so I updated text2pcap with the following new command-line
options:
IP dummy header fields:
--ip-addrs <src>,<dst> Set source and
destination addresses.
--ip-id <id> Identification value for dummy
IP header.
If <id> is 0, then use random
non-zero value in each
packet. If <id> has a trailing
'+', then start with
the given value an increment by one
for each packet.
Example: --ip-id 100+ to use
100,101,102 etc.
--ip-ttl <ttl> Set TTL value.
--ip-dscp <dscp> Set DSCP value.
TCP dummy header fields:
--tcp-seq <seq> Set initial sequence number.
If <seq> is 0, then
use random initial value.
--tcp-ack <ack>[,<incr>[,<freq>]]
Set the initial ack number, increment
and increment
frequency. If <ack> is 0 then
use a random initial
value. If the optional <incr>
is non-zero, then
increment <ack> by the given
amount on <freq> packets.
Default value for <incr> is
1000, default value
for <freq> is 1.
--tcp-win <win> Set value for window field.
I also plan to make changes to support open and close
handshakes.
Is there any interest integrating these changes into code
base?
