Nop, every time pp runs, creates an empty so_rules.rules file with the
same error described above ...

The same error will appear because PP tries to validate your Snort
configuration file and also looks for certain settings in there
(such as dynamicengine/dynamicdetection directory)

If you comment out your rule include lines, does

snort -i ethX -c /location/of/snort.conf -T

run to completion?


Yes, validates until end:
