[panda-users] Question for file_taint

[Duo Zhang]

Hi Andrew,

Thanks for your replay. I tried install_ubuntu.sh script to install panda,
and also success. However, the error still persists when I use the
file_taint. My experiment is based on this one:
https://github.com/panda-re/panda/issues/607

Thanks,
Duo
