    To whom it may concern,

         Hello, my name is Adam Plesniak and I am a summer intern here at NASA's Goddard Space Flight Center. My mentor and I are using your program tcptrace to analyze some tcpdump experiments we have been doing. We were wondering, how, using the data that your program provides, do you determine the set maximum window size of a specific, lets say a single file, transmission? Is the maximum set by the receiving computer or the sending computer? or possibly the lowest set maximum window of the two? Any help on this topic would be great, also, in your program as well as the tcpdump program, the optional data mss<****> comes up when an S flag is present in a tcp transmission. What exactly does mss mean, and what does the number it gives (i.e. 1024) tell us? Any information you could provide would be very helpful. My mentor and I really enjoy your program and think its great for making tcpdump easier to read. Thanks so much for your contribution!
