Posting snippets of packet captures with reasonable problem reports are generally welcome. A lot of us here enjoy the challenge of trying interpret a stream of bytes with the hope of actually diagnosing the higher level issue that may be causing the problem.
That said, some of us do this work for a living and get paid quite a bit of money to do it, so doing it for free is only viable if it doesn't take a lot of time. Any time I respond to such requests is out of a spirit of mentoring the community and also hopefully giving myself a little confidence that I actually sometimes know what I am talking about :-)
So please post, but also understand the context of the community.
Regards, Martin

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
