[tg] IPv6 and TG, first step !

[Hugues VAN PETEGHEM]

Hi all,

As I'm going on holidays for the next 2 weeks, here is the first step of
my work about generating IPv6 using TG. I achieve to do that, but the
code you can find attached is not yet clean and well documented. I will
do that when I'll come back to work.

Anyway, here is an example of IPv6 traffic generation (all the files can
be found attached):

°°°°°°°°°°°°°°°°
CLIENT:
**********
[root at pc06 root]# cat udp_client.tg
on 0:15 udp 2005:0:0:2::2.40000
at 5 setup
at 6 arrival constant 0.01 length constant 576
time 20
[root at pc06 root]# tgv6 -f -i udp_client.tg -o udp_client.tg.out
[root at pc06 root]# dcatv6 udp_client.tg.out > udp_client.tg.txt
[root at pc06 root]# cat udp_client.tg.txt
(...)
Event Time      Type            Address                 Id      Length
------------------------------------------------------------------------

5.005877        Setup
6.016049        Transmit        2005:0:0:2::2.40000     0       576
6.025924        Transmit        2005:0:0:2::2.40000     1       576
6.035927        Transmit        2005:0:0:2::2.40000     2       576

26.006568       Teardown

And, on an other terminal:

[root at pc06 root]# tcpdump -i eth0 host 2005:0:0:2::2 -w cap.cap
tcpdump: listening on eth0

1999 packets received by filter
0 packets dropped by kernel
