Collection of useful, relevant or inane places on the the Internets for 10 Dec 10:
- Company A – Network Management and Cisco UCS – Josh Gant explains that the networking inside a UCS chassis is actually a bunch of fancy virtual network adapters. Given my post a couple of days back, I agree. Although a bunch VMware folks where offended that I don't see the vSwitch as the saviour of the world.
- Why Working On A Large Enterprise Network Isn’t Always A Win « PACKETattack –
So am I saying there’s no good reasons to work on a big network? Not at all – there’s lots of reasons, not the least of which is that you get to play with all the cool toys. Big networks need big iron, big circuits, big data centers, and big budgets. Big networks usually have big problems to solve.
Ethan puts the all round balanced debate on working for big or medium sized companies. FWIW, I agree with his point of view.
- Cisco Blog » Blog Archive » 5 Things I Learned At Gartner Data Center – Vendors go to Gartner conferences to hear what their customers will be told for the next busienss year.

- Maybe you only need it because you have it — The Endeavour –
It may be even harder for organizations to realize it has been caught in a cascade of needs. Suppose a useless project adds staff. These staff need to be managed, so they hire a manager. Then they hire people for IT, accounting, marketing, etc. Eventually they have their own building. This building needs security, maintenance, and housekeeping. No one questions the need for the security guard, but the guard would not have been necessary without the original useless project.
Yep, we know.
- Stuxnet: Be Afraid | The Networking Nerd –
After digging into the payload and operation of the virus, the malicious intent cranked up two or three more notches. The virus used a data cable connect between the PC and a Siemens Programmable Logic Controller (PLC) to hop into the PLC where it really started its nefarious work. Firstly, a rootkit was installed to hide the infection. Then, using the PLC it started messing with variable frequency drives that were slaved to the unit.
Very detailed summary of the Stuxnet virus. Must read.
- Ethernet Fabric – Looks like Brocade is making an attempt at social media. By not using the name 'Brocade' anywhere, or any reference to their core product, FibreChannel networking.
- ASCII Table – The Pronunciation Guide –
! = bang : as in "quit, dammit!" while exiting vi and hoping one hasn't clobbered a file too badly
Love this piece of Unix humour.
