Łukasz Dywicki commented on PLC4X-286:
--------------------------------------
[~adrlzr] This seem to be an issue with system level permissions to get to
lower layer. Normally user space applications are permitted to access IP layer,
but not ethernet. This is exactely what pcap transport attempt to do.
Do you run your program as an administrator? I recall I had a lot of trouble
with that even under linux until I realized that entire java executable (not
only your JAR) must have valid permission flags.

> I found some work done towards implementing the
> [profinet-DCP|https://profinetuniversity.com/naming-addressing/profinet-dcp/]
> protocol on the [feature/profinet
> branch|[https://github.com/apache/plc4x/tree/feature/profinet]].

> replaced with the s7 protocol?
> If someone would have the time to guide me, I could work on it to update,
> test, and bring this discovery feature to PLC4X.
