LMTV WTF Live | When is a FTP Error An Error (by Tony Fortunato)



Live Event Time - Tuesday, November 10, 2015 - 9:30 AM PST


WaldoTony FortunatoWe caught up with +tony fortunato this week and gave our viewers a chance to ask live questions regarding one of his recent papers in LoveMyTool.com.

According to Tony, ...

"It is always fascinating how different applications report the same problem. It is of tremendous values to ‘break’ applications or cause intentional errors to see how applications behave what they report, or not report.

The behavior and reported error will vary from product to product and from version to version, so it helps to repeat your test every so often. Don’t forget that some applications can use multiple protocols and may mask, or misreport error messages.

The same point applies to your tool of choice. Does your protocol analyzer report on any ftp or application error codes? And lastly are there any other protocol clues to help zero in on this issue, like a TCP RST, ICMP error message, etc.."

Tony was using FTP and various FTP clients as an example of this methodology.

Upon popular demand, +Paul Offord is giving us a re-run of his well attended SharkFest 15 session, which covers performance analysis theory and the practicalities of using the TRANSUM free plugin for Wireshark.

The purpose of this two-part LMTV presentation is to look at how network engineers can use TRANSUM to quickly analyse a slow response time problem and produce concrete proof of the cause.

Specifically, in Part 2, Paul will demonstrate the analysis of two problems using TRANSUM and close the session with a look at some related assets available from the TribeLab project.

Paul has had a 37-year career in the IT industry that includes roles in hardware engineering, software engineering and network management. Prior to founding Advance7, he worked with IBM, National Semiconductor and Hitachi Data Systems. Paul is leading a project called TribeLab with the objective of promoting evidence-based troubleshooting to the IT industry. TRANSUM is one of the first outputs from the TribeLab project.

The purpose of this two-part LMTV presentation is to look at how network engineers can use TRANSUM to quickly analyse a slow response time problem and produce concrete proof of the cause.

Specifically, in Part 1, Paul will cover the concept of Request-Response Pairs, the RTE Model for measuring response times and the shortcomings of the standard Wireshark “Time from request” measurements.

Live Event Time: Thursday, June 4, 2015 - 10:00 AM PST


LMTV SharkfestDon picture After our interview with +Gerald Combs last week, we have officially kicked off "LMTV Sharkfest", a series of technically focused presentations by the shared sponsors of +SharkFest Wireshark Developer and User Conference and LoveMyTool.

First batter up is +Don Shin of +Ixia | Anue Network Visibility Solutions. Don is a member of the Ixia Technology Partner Development team. He is responsible for managing and evangelizing the Ixia security and applications portfolio. Don has a passion for helping IT organizations build stronger networks by adopting rigorous testing practices.

His vendor neutral presentation will be about maximizing security and monitoring investments. In today's world of crippling cyber attacks and dynamic applications, organizations need to know that their networks are resilient to handle the worst that cyber criminals can throw at them.

But even with spending on security and monitoring technologies at an all-time high, how confident are you in vendor decisions and the architecture you are implementing? Learn how to replace guesswork-based uncertainty with fact-based confidence to maximize your investments.

Please join us with this live event and participate with Q&A.

In the past, here at LoveMyTool, we have talked a great deal about InteropNet, the mission critical network that runs the show floor as well as supporting all the peripheral functions including classes and live demos.

Tim-outside-officesThis Friday we will interview Tim Titus, CTO and co-founder of PathSolutions, an InteropNet partner.

Tim will come to us live from inside the NOC which hopefully will be fully operational by then (three days before showtime). Tim will be sharing with us his experiences at Hot Stage and the network troubleshooting he did, and the technical challenges he and his fellow team members will be confronted before, during and after Interop.
