Wireshark · Ethereal-users: [Ethereal-users] Ethereal WebSphere MQ dissection on segmented message

["e.soden-mls@xxxxxxxxxxx" <e.soden@xxxxxxxxxxx>]

Hi,

 I’m using WebSphere MQ dissector built within ethereal 0.10.14. I’ve made a simple test send 256K using application segmentation. I split a 256K into 31,5K segment.

 

 I get some trouble to see MQ packet in ethereal:

  - First packet (MESSAGE_DATA) is displayed correctly in the packet list pane. But nothing appears in the packet details pane.

  - Last MESSAGE_DATA is displayed correctly.

  - All MESSAGE_DATA between first and last packet are dissected as “TCP segment of a reassembled PDU” and I get for each of them a “TCP ACKed lost segment”.

 

What happened there? Somebody could explain what happens?

I attach to this mail a capture file to test it and a small png file showing the behavior.

 

Regards,

Manu
