Dear Vítor Bernardo,
my name is Alessio Botta and I am one of the developers of D-ITG.
I just made a test with Ubuntu Server / 2.6.27-9-server and DCCP
CCID 3. I got no segmentation faults.
Could you please provide us more information regarding your tests ?
In order to reproduce the error we would need to know the
versions of D-ITG and g++, as well as the commands you used to
compile and run D-ITG.
Best regards and Happy Holidays.

Hi all,
I'm using DCCP in my MsC thesis in order to evaluate the it performance
to delivery some kind of application, such as VoIP. At this moment, I'm
doing a testbed evaluation of DCCP and I'm having some problems.
To perform these tests I'm using D-ITG traffic generator in a Linux
machines running Ubuntu Server / 2.6.27-9-server. As you should know, by
default the Linux implementation of DCCP uses CCID2. With CCID2 I have
no problems and I can run the tests, but when I configure the machines
to use CCID3, I got some segmentation faults. In attach you can found a
trace of error.
I don't know it is a configuration problem due to my knowledge about
DCCP. To enable DCCP with CCID3, I'm doing the following:
modprobe dccp
modprobe dccp_ccid3
sysctl -w net.dccp.default.seq_window=10000
sysctl -w net.dccp.default.rx_ccid=3
sysctl -w net.dccp.default.tx_ccid=3
Does anyone can help me? Has anyone used the DCCP CCID3 with the D-ITG
before?
Thanks in advance.
