Repetition is one of the keys of learning

I recently posted an update about Laura Chappell’s Chappell University Online seminars. I attended one of these seminars today. What a great experience! I always try to attend Laura’s events and always pickup a tidbit that makes my life as a network manager easier. She gives you information about tools you can use to fight the battle of “the network is down”. Most of the time the network is behaving as designed. It’s poorly written applications or too high user expectations that create issues. So, if you want be the expert on fighting the network is “bad” syndrome – check out Laura’s presentations – I did and I learned something new…

There are many options in Wireshark that go unused or require some understanding and practice to use.  Laura is great about going under the covers and revealing exactly what you need to use and how to use it. I have used ethereal (Wireshark’s predecessor) and Wireshark for several years now. It is only with continued education by Laura on the features that I am gaining a better understanding of this network analysis tool and the ins and outs of using it. For example, the Statistics – TCP Stream Graph – Round Trip Time Graph option. I thought my copy of Wireshark was flawed as I never received any results in the graph. Today, Laura’s online seminar showed me that I was likely reversing the results and ending up with an empty result set. Now I know! You can almost always learn something new about something old. Just keep digging! Thanks Laura for the tip.
