July 12 2016 - MUG Meeting
We meet at 6:30pm on the second Tuesday of each month at the Farmington Community Library.
Network Packet Sniffing with tcpdump and Wireshark
Have you ever wondered why that download is running slow, why the web site is lagging, or maybe you are just interested in how network traffic looks at the bit level?
Well Tony Bemus and Jim McQuillan will demonstrate how to trouble-shoot network traffic from both the command line with TCPDUMP and from the GUI with Wireshark.
Tony will then give a quick overview of the new wireshark 2 GUI. Then demonstrate some basic analysis of the TCPDUMP and or Wireshark packet capture (PCAP) file.
Jim will cover how to set filters to limit the packets being captured to only those that you are interested in, rather than the firehose stream of data that could be flowing on the network.
Using packet dumps that we'll capture live during the meeting and some of the example captures from the wireshark website (https://wiki.wireshark.org/SampleCaptures), we'll show how to dig down intothe packets and see what's going on.
