FASP protocol specification
Anyone have FASPexperience? This is the protocol which the Aspera client & server use to transfer files (https://www.ibm.com/downloads/cas/7D3...). Wireshark doesn't ship with a dissector, but I found one on GitHub (https://github.com/sky-bro/FASP-wires...) and it seems to produce coherent decodes, from what I can glean from reading the links above and from poring through pcaps
But, I'm analyzing a pcap now full of opCode 25 frames, which this dissector decodes as 'RETRANS'. RETRANSmitted traffic doesn't fit what I'm seeing, so I'm wanting some sort of sanity-check
I suppose what I really want is IBM's FASP protocol specification ... but that seems to be hard to come by ..
Anyway, if you have experience analyzing FASP and have seen opCode 25 packets, I would appreciate hearing what flavor of FASP you decode it as
