Hi John,
Although there is not a strict charter for what is appropriate for the
Wireshark-users list, I personally feel that it is about "helping people to
use the wireshark tools to enable them to solve their problems". That often
includes helping them understand protocols and even doing some analysis for
them. I think this list is really great in that way.
Your question however is not to help you solve your problem yourself, but
asking other people to analyse your files for you. Even though there might
be many people here (including me) that would love to take a look at the
files and analyse it for you, I think your request is bit to much a request
for free consultancy. Of course that is my personal opinion, others might
think differently.
I would encourage you to take a look at the tracefiles yourself, read the
FTP RFC (http://www.faqs.org/rfcs/rfc959.html) and use this list for helping
you get the most out of wireshark and/or fill you in on some details about
the protocols you see in the tracefiles. We're here for you :-)
If you do want an expert to analyse the collected data for you, you might
want to contact one of the network analysis consultancy companies that are
out there. Just to name a few:
GearBit (http://www.gearbit.com/)
The Technology Firm (http://thetechfirm.com/)
Network Protocol Specialists (http://new.networkprotocolspecialists.com/)
Bitcricket (http://www.bitcricket.com/)
SYN-bit (http://www.syn-bit.nl) <-- Shameless plug
Cheers,
Sake

Subject: [Wireshark-users] Analyzing a "broken" FTP session
Group:
I'm not sure if this is the correct forum for this but I am hoping to get
some help identifying a problem that sometimes occurs between an FTP client
and server. (If this isn't the right forum can someone point me in the
right direction?)
I have PCAP files made on both systems using tcpdump that have captured a
recent failure, but I do not have enough expertise in packet analysis or the
guts of the FTP protocol to read them and draw a definitive conclusion
regarding why the connection "broke".
If someone can help I am happy to provide more information regarding the
systems themselves, the network topology between them, and the trimmed PCAP
files for analysis.
Thanks in advance, JC
