Title: Message
i sometimes use the abovementioned to look at FTP sessions to see if the TCP layer is performing ok. When i select a packet and try and activate the tcptrace type graph, sometimes, it doesnt work.  By this, i mean that i get a very weird looking tcptrace graph, that doesnt make sense at all.  its all straight lines, step changes, totally weird.   Then i select other packets from other ftp sessions and i can see the proper tcptrace.
 
can someone tell me what conditions need be fulfilled in order for me to see the tcptrace graph ? why can i see the tcptrace for some packets and not for others ?
 
thanks alot,
