[Taslug] Hobart Thursday April 20th Meeting - Introduction to Wireshark and Troubleshooting Performance

[Scott Bragg]

This month we will be meeting at Kickstart Arts in Newtown again, except 
this time in the main 'school hall' which I think is in the building 
next to where we met last time. I'll be putting out some signage but 
head in that general direction.

This month we have a new TasLUG member Leigh Finch speaking about 
Wireshark. Since you can dive pretty deep into wireshark and network 
analysis I'm hoping this could be the first of a couple of talks about 
troubleshooting network and application performance. There is also be 
some time for a lightning talk or two if you have something you want to 
discuss or demo.

We'll get in some Pizza from Pizzarazzi and there will be tea and coffee 
available but you can also bring along a refreshment. I see sometimes Mr 
Burger parks just down the street opposite the sports center.

When: Open at 6pm for 6:30pm start/pizza order Thursday 16th February 
2017

Where: Kickstart Arts - Hobart Makers Inc space, St Johns Avennue 
Newtown

Agenda:

- 6pm arrive and chat
- 6.30pm - We'll put in a Pizza order, lightning talks and demos.
- 7pm - Talk - Introduction to Wireshark and troubleshooting performance
- 8pm finish up

Enterprises often struggle with application performance, with slow 
applications blamed on anything that appears to be  black box. 
Understanding how applications communicate and how the Kernel processes 
TCP is crucial to diagnosing performance problems. Wireshark is often 
described as the grandfather of protocol analysers, with hundreds of 
built in protocol dissectors and an built in LUA scripting capability. 
Wireshark is and will continues to be the surgical tool of choice when 
diagnosing performance problems.

We will cover the following topics:
* Sequence analysis
* Network delay
* Server Delay
* Payload transfers
* TCP streams
* Exporting objects
* SSL/TLS analysis/decryption

How to get there:

Kickstart Arts is in St Johns Avenue New Town. Here is an Open Street
