Hi Anthony,
The behavior of pfFindNode was changed slightly in pf3.0.1, since it was
found to be inconstistent, and different from the man page description.
This change may be causing your code to break.
Try setting the following environment variable:
_PF_NODE_FIND_REQUIRES_EXACT_TYPE
This environment variable can be used to revert the behavior of
pfNode::find (also called from within pfNodeLookup) to what it
was before being fixed for pf3.0.1. The old behavior would
carry out an exact type comparison (pfIsExactType) instead of
using pfIsOfType as suggested by the manpages.
As regarding pfPrint, try setting verbosity to PFPRINT_VB_DEBUG.
This generates the most output, and should include your node names
down to the leaf level.
Hope this helps,
Regards,
Paolo
