Hi genericCC team,
The problem I meet is that when I run my command as the terminal shows, the Copa only run 3 seconds and exited. However, I run the similar command as the figure shows for Remy, it works well.
So, my command for Copa is right or not? Or, there are other bugs?
Thank you for your any response.

Hi Venkat,
I am trying to run some expts with Copa for one of our paper revisions. However, Copa fails with a seg fault regardless of the delta_type used. Here are the console dumps from two different runs (I had ./receiver running in another terminal window for both these runs):
shivar@shivar-desktop: Tue May 04 20:01 genericCC $ ./sender serverip=localhost cctype=markovian offduration=0 onduration=60000 delta_conf=do_ss:auto:0.5 traffic_params=deterministic,num_cycles=1
Using MarkovianCC.
Will do slow start
Using Automatic Mode with default delta = 0.5

All this time, the receiver doesn't print anything. It's a blank screen on the receiver terminal.
I am using 64-bit machine with Ubuntu 18.04 (kernel version 4.19.0-0419000-generic), g++ 7.5.0 and makepp 2.0.98.5.
This issue didn't happen in the summer of last year. It ran smoothly then. Three of us in our group (in three geographically different locations) have been facing the same issue for the last few months now.
Is this something that can be fixed quickly? Or any pointers?
Thanks!
Regards,
Shiva
Hi, is there any document or paper explaining how it work?

Is there a clue to solve this? I am using Ubuntu 12.04, g++ version is 4.6.3. Is it possible that the g++ version is too old? But I am trying to run an experiment with it in Mininet, which only supports Ubuntu 12.04 (Linux kernel 3.13.0).
Thanks in advance!
