Break the Network Emulators out of the Cloud

Cisco IOU and JunoSphere
Recently both Cisco and Juniper have announced the availability of online resources to provide hands on training over the internet. They have built software emulators in the cloud that can be accessed remotely for a cost. These solutions are based purely around the certification programs and therefore are pretty rigid in the topology that are provided, not to mention the re-occurring cost.

Rack Rentals
There are training providers such as Internetwork Expert (http://www.ine.com/) and IPexpert (http://www.ipexpert.com/) who provide rack rentals based on their training materials. These guy cannot possibly compete going forward. To keep these sustainable they will need to reduce the overhead of building physical racks, providing power and space for the racks. Using emula…

ASR1006 Dual Route Processors Password Recovery - Tip

I recently ran into an issue when trying to perform dual route processors password recovery on a Cisco ASR1006
Problem
After breaking into rommon mode and using confreg to ignore the startup configuration, during the rest the ASR1006 loaded the startup configuration!!!!!!!!
Solution
So quick and simple, I pulled one of the RP and preformed password recovery running on a single RP. All went according to the Cisco documentation

http://www.cisco.com/en/US/docs/routers/asr1000/install/guide/routers/asr1_hwc.html#wp1045971

After the system running on a single RP was recovered and fully booted I waiting for 5 minutes just to be sure; then I inserted the second RP and allowed everything to sync up.

All was well again :) phew

Note: The system was previously fully functioning with dual RPs; a configuration error was made during Tacacs+ configuration which resulted in lockout.

Summary
I hit an issue recovering and ASR with dual RPs, so rather that spending hour researching, I decided very quickly to go …

Dell Latitude D830 SSD Upgrade

Slow Laptop Syndrome
I have a LATITUDE D830 : INTEL CORE 2 DUO T7500 4GB Ram from 2008, I did get a fairly high specification at the time, so it has always had pretty decent performance. However I haven't been using it for a while and when I did it seemed slow compared to my Core 5i desktop computer. (I use Windows 7 ultimate with the latest updates)

Laptop for Work
Now I might be doing a fair bit of travelling to customer sites in the near future and the last thing I want is a poorly performing Laptop, so I decide to ditch all the crap I had on it like iTunes, movies, miscellaneous software and cut back to a basic "work" PC. After all I do have iPhone, iPad and new kindle (soon) for all my multi media needs.

I purchased a "Corsair 120GB Force 3 SSD 2.5" SATA-III 6Gb/s Read = 550MB/s, Write = 510MB/s" from ebuyer.com. Now I am guessing that SATA-II rather that SATA-III on the system board, but the price difference between SATA-II and SATA-III was nothing …
