Anyway, the DLSW dissector must be fixed as this may also happen with valid
DSLW packets.

Regards,

Olivier

|Hi,
|This is strange I suspect this frame is H323 as the port is 
|1720, I've no idea why
|it ends up in the DLSw dissector, perhaps the H225 dissector 
|rejects the packet ?
|
|
|Best regards

||
||Hello,
||Thank you for the help. The problem was fixed, but then 
|reapeared again
||today with a different packet. This one is not decoded 
||correctly by ethereal
||and I guess that is why it cannot go into pdml. Here is the situation:
||
||tethereal -Tpdml -r b2.cap
||
||.....
||Unhandled exception ("XCEPT_GROUP_ETHEREAL", group=1, code=2)
|
|The exception is thrown since the protocol dissector is pointing at an
|invalid location in the packet data for the given protocol field.
|
||This is using the development version from today (26 april) 
||tethereal -v
||tethereal 0.10.3 (CVS 20040426133230)
||
||Can you please take a look? I am attaching the troublesome 
||packet again.
|
|The problem lies within the "Data" portion of the DLSW 
|protocol (data part):
|incorrect offsets and lengths are used to highlight the matching packet
|data.
|
||If it cannot be decoded can it be skipped or something?
|
|We'll have to provide a fix for this error.
