Hi Ronnie,
I found this german Diplomarbeit at
http://www.abmlinux.de/DA/Diplomarbeit.pdf
and it seems interesting for me to study it and to try the
reimplementation, but in this Diplomarbeit they write about at least 3
months of work.... so
"What we need is to make ASN2ETH encoding agnostic ... and make it
easy to implement and add new encodings for asn1 defined protocols."
I will try it.
If I need some help, may I ask you ?
Best regards
Herbert

I see you add a new library ICONV.LIB to the makefile and i assume
to the dependencies.
Is this a library available on all windows boxens ?
libiconv is already used if you compile with GTK2
I notice there is a libiconv package required for windows, is this
this library referenced from the Makefile.nmake?
It's the same
I dont really like that this dissector tries to implement its own
handwritten BER unmarshalling. There is already a too many of these
reimplementations of BER decoding helper functions in ethereal and we
should not add more. The ones we do have in packet-ber.c are the only
ones which are reasonably well tested, works reasonably well and are
used by teh automatic asn.1 to ethereal compiler.
It seems bacapp is really just a protocol described by asn.1 and using
BER for encoding.
most of the dissectors I added described by asn.1 in my headerfile
Instead of adding to this one what really should be done is to
reimplement BACapp from scratch as a dissector generated automatically
from the ASN.1 definitions and using ASN2ETH.
Is the BACAPP ASN.1 protocol specification publicly available?
