Hi, I got the following question regarding tcpdump and I would appreciate your help/feedback:
--Scenario
I am instructed to capture the network traffic by getting the tcpdump data/files of our network for every hour.
--Problem
Some of the connections are still open when the capture is done at the end of 30 minutes. How do I link these open connections in different tcpdump files?
--example
Connection A: 192.168.10.1:1686 --> 192.168.10.22:139
connection A starts: 12:25
connection A ends: 12:45
Data capture: 12:00-12:30 (file1), 12:30-1:00 (file2)
Will there be two connections (for connection A) -- one in file1, the other in file2? Will their connection start time be the SAME or DIFFERENT?
Please help!!
Thanks!!
Jay
