Hi Jörg,

When using tshark from head I have a bunch of problems right now:

1) stderr is getting spammed with
(process:9870): Capture-WARNING **: Dissector stp incomplete in frame
41915: undecoded byte number 57 (0x0030+9)


You seem to have activated the prefs.enable_incomplete_dissectors_check.
Simply go to Preferences -> Protocols and uncheck "Look for incomplete
dissectors".

It is (normally) disabled by default

2) -T fields -e _ws.col.info isn't working (empty column), both with
and without -V


The right field name is _ws.col.Info

typo ?


I don't think so: the column itself is named "Info", not "info". The field
generated uses the name of the column, as configured in your Wireshark
preference file.


Cheers,
Pascal.

3) Some of my .vwr captures seem to only decode in tshark (with and
without -V) but
   don't decode with -2 or in wireshark (I'll open a proper bug for this
once I have more
   info). Btw, how can I convert .vwr files to pcapng? Both Save and
Save As are greyed out.

Thanks
   Jörg

We are stuck with technology when what we really want is just stuff that
works. Some say that should read Microsoft instead of technology.
