More Question than answers (This series will be based on an enterprise with >20,000 dot1x devices) I have been looking into dot1x authentication for Wired and Wireless devices based on device identity using x.509 Certificates. While I understand PKI, AAA, PEAP and sorts I had never really had the opertunity to bring these technologies together. I quickly found out that despite this stuff being around for years,  it was difficult to answer the following questions: Which PKI solution should I use? Which AAA solution should I use? How to setup the PKI solution? Does the PKI server need to be part of AD? What if the clients are not in AD e.g. Wireless Tablets? How do I issue certificates for devices? How to configure the devices (wired and wireless)? What AAA server do I use? How do configure the rules and policies and identify clients?   What are the answers? I am going to kick off a series here at networking-guru.net that tries to address the question above; I have l

I got around to creating a more stable version of my android subnet calculator with the limit removed from the csv file size. Please enjoy and leave feedback on the market place. https://play.google.com/store/apps/details?id=net.networkingguru.SubnetMasterRelease  

I thought I would challenge myself to write a mobile app. I personally have an iPhone, but didn't want to invest in a MAC to develop an application and then having it rejected by apple. So I opted for and android based app. I had a look around at the subnet calculator market and though I could do a better job.

There are still lot of refining required, but I feel it is ready for a beta release.    

I done the exam, and I am please to say I passed. So the lab-ing and the two PDFs JNCIA-Junos_SG_part_1_09-16-2010.pdf JNCIA-Junos_SG_part_2_09-16-2010.pdf And a bit of surfing the web were enough. That is not to say everything in the exam was familiar, I did have to think seriously about some questions which puzzled me. So the next step will be to go for specialist, but because of workload, it's going to take a little longer that 15 Days.

It's a Wrap This is the last on this series, it has been hard work fitting in the time (very late evenings) and frustration trying to dump my notes into wordpress. I need to do more reading before the end of the week as I have booked the JNCIA-Junos exam. The start of the Journey has been interesting, and I hope to reach my first mile stone JNCIA-Junos, then I decide if I can go much further with the resource I have at my disposal. Services and Users Part NTP I had some issues getting NTP synced on the last video, I eventually worked it out so here is the final installment. Final word That me finished this series, I hope people find to useful, I know I have found it of great value albeit a tiring one.

This serious show clearly how tiredness cause simple mistakes :) Some Troubleshooting
