Yes, normally do not run pktgen using the command line format, but I use the ./tools/run.py or ./tools/run.sh.

The run.py python script is the newer script and it uses .cfg files in the ./cfg directory to execute pktgen with the correct options. The run.sh script needs to be edited to run the correct options. I would suggest using the run.py script as in:

$ ./tools/run.py default

And yes pktgen needs to be fixed to not leave the tty in a funny state. I hope I can get to that later.
