No results when running the pantheon

[Yee Young]

Hello, I have some iuuses with running the pantheon.

When I test schemes such as bbr in emulated networks locally,  the result files do not contain any arrival or departure events.

Here's the output:

python test.py local --schemes "bbr"

All tests done!

Thank you very much.

Hi Yee,

The error was in the log: "Attempt to set 'bbr' congestion control failed: No such file or directory." Please debug by running `./src/wrappers/bbr.py` manually, but the missing piece is https://github.com/stanfordsnr/pantheon#setup.

Best,

Francis

Thank you. I found that it's my system that did make bbr avaliable. I used sysctl to activated bbr.
