how do i capture packets between two hosts? once packets are captured, how do i know the cause of the problem? like email alerts sent from Oracle server to Exchange server sometimes fail. is there something like a reference that i can compare against my captured packets? asked 26 Feb '14, 00:51 rino19ny |
One Answer:
by following the steps described here: http://wiki.wireshark.org/CaptureSetup and here: http://wiki.wireshark.org/CaptureSetup/Ethernet or http://wiki.wireshark.org/CaptureSetup/WLAN whatever applies in your environment.
by analyzing the problem description, then 'mapping' that description to involved protocols (http, smtp, whatever) and finally by looking at the matching connections between the involved systems (Oracle and/or mail sever).
Most certainly no, as every network is different. However, you should learn something about the basic protocols (IP, TCP, UDP, http, smtp, etc.). With that knowledge (and some experience), you should be able to figure out if the connection you are analyzing shows any problem. Regards answered 27 Feb '14, 05:23 Kurt Knochner ♦ |
