Hi James, I looked at the trace in question, and it appears to contain some HR information, so I'd have to get an NDA on file to send the pcap. It's not HIPAA PHI, so I would not need a business associate agreement or a patient release, thankfully.
If you want to go through that much trouble to help me, more power to you. Would you rather just give me a hint of what you're looking for and let me be your eyes? --Eric -----Original Message----- From: James Washer [mailto:[EMAIL PROTECTED] Sent: Thursday, September 04, 2003 6:32 PM To: [EMAIL PROTECTED] Subject: Re: [RLUG] [OT] TCP/IP Weirdness what sequence number is being acked ( in the repeated acks ) , what it the sequence number and size of that 'last' packet, and what get's acked after the client receives that last packet.... mail me the pcap file if you care to. - jim On Thu, 4 Sep 2003 17:55:01 -0700 "Robinson, Eric R." <[EMAIL PROTECTED]> wrote: > This is OT because none of the participating equipment runs Linux, but I > figured it was worth asking anyway since some of you are network geeks. > > I have an application called ProLaw that runs off a NetWare server on the > other side of a PIX firewall.
