Mac OS X

The files located in the client's /dev/bpf* directory must be world-readable to enable packet-level recording. For example, using Terminal to apply:

chmod a+rw

to all the bpf* files (bpf0, bpf1, bpf2, etc.).

Conductor tries to handle this on behalf of the user, but there are some cases where the OS will randomly toggle the permissions, breaking packet-level recording until the next time Conductor starts.
