Good day,
I’m using bro version 2.0-372 with a new git checkout from master as of 2012-05-27 on Centos6. I’m having an issue where the print statement in the policy debugger displays nothing. Breakpoints and stack tracks seem to work correctly but not being able to inspect variables is making playing with policies frustrating.
Is this a known issue or is there some type of preprocessing make inspection work?
Thanks,
Chris
