Wireshark also supports the encapsulation iFCP.
It would probably be easy to add mFCP (dead brocade protocol) as well
if an example capture was made available.

Use a linux box to run wireshark on instead.
It is cheaper than terminal servers and as a bonuson the same
hardware, processing the same capture files, wireshark will run
several times faster on linux than w2k3

the OSX tests was on similarly specced hardware. I could obviously
not test how OSX Wireshark behaved/performed on the same physical
machine I tested with Windows.

The congestion window can not be determined by looking at the packets

In general it is impossible to tell what the congestion window is by
looking at traces.

wireshark has the without doubt most complete dissector for SMB of any

this may or may not change for tvbuff so it would be unsafe to assume
you can pass tvbuff pointers from one instance
Prior to the previous segment lost there is a delay of ~500ms
which is a common tcp retransmission timeout.
Before this previous segment lost segment there were probably an
earlier segment twice, once before the 500ms timeout and once
immediately together with the previous segment lost segment.
This document contains a lot of information about this protocol (and others)
and would likely be very useful for someone planning to start
implementing a dissector.

Hi,
Do you have a nic with large segment offload in the host where you
capture these large segments?
If so the packets will be split into smaller segments in the NIC
itself, below the point in the stack where you captured the packets.

wireshark uses heuristics to determine if something is a keepalive or not:
It assumes it is a keepalive IF
the left edge decreases by one (sequence number 1 smaller than the next
expected one)
the segment contains exactly 0 or 1 bytes of payload data
/* KEEP ALIVE
* a keepalive
Bill,If you are working on the TDS dissector,could you also look into making the heuristics a bit stronger for this dissector?It is fairly commong that the payload for certain bulk transport protocols are mistaken for TDS.

Maybe Johnnie can join forces with him finishing the dissector and
