Update (10:00ET, 14-Jun-2014): See below for a copy of Friday’s Iraqi MoC order to disconnect social media.
Iraq is descending into further violence, as militant group ISIL takes control of Mosul and beyond. Renesys has observed two large Internet outages this week (here and here) that our sources confirmed to be government-directed outages. These interruptions appear to coincide with military operations, amid concerns that ISIL forces are using Internet websites to coordinate their attacks.

The screencapture image in this tweet shows an email message announcing the latest shutdown. It reads:
Dear Valued customers
Due to the current security situation in iraq and as per the MOC instruction sent by the PM Mr Nori Kamel Al-Maliki ,the internet service will be suspended for the below provinces until further notice starting from today Thursday 12/6/2014 , Continue reading
Couple of quotes from John Chambers keynote during Cisco Live that I seemed to leap out at me: “You are going to see a brutal, brutal consolidation of the IT industry where out of the top five players, only two or three of us will be meaningful in as quick as five years.” “When we […]

Having been in this industry longer than I care to think about (I cut my teeth in operations and systems programming on mainframes and early Intel 8080-based ‘microcomputers’), I’ve seen a few technology innovations that were truly disruptive and some that claimed to be but ultimately morphed into something else or were relegated to a niche (remember the Infiniband ‘revolution’ in the early 2000s?). Software defined networking and network functions virtualization clearly threaten to upset the status quo, which in this case, is the vast ecosystem of hardware-based switched and routed networks, and the network equipment manufacturers who build the gear. Cisco, arguably, has the most to lose, but potentially, the most to win also.
In Peter Burrows’ recent Bloomberg article, reflecting how SDN has become mainstream news, he points out that the existing market for switches and routers is growing at the very modest rate of three percent a year. While this business is the lifeblood of companies like Cisco, Juniper, Alcatel-Lucent and Huawei, it is becoming commoditized with downward price pressure and diminishing technological differentiation. These players can certainly Continue reading

This article at Seeking Alpha shows that John Chambers sold more than 30% his Cisco shares last month and is just one of 8 other executives who sold significant numbers of shares in the last month.

Couple days ago I made an interesting talk about Video Traffic over Internet. Sales engineer goes to company and he claims that Video traffic can be carried over Internet without any problem. This is of course wrong and to understand why I have to explain some technical concepts. Main take away from this article is […]

You might be asking yourself why a network engineer would be concerning himself with a product like Chef. It’s a long story, but lets start by saying that my interest was first peaked when I heard that the new line of Cisco Nexus switches would have a integrated Chef client. I’ve known about Chef and Puppet for a long time, but I’ve never really sat down and looked to see how they worked. So rather than starting with Chef on Nexus, I thought it would be prudent to get some base experience with the application in a more ‘normal’ application.
So how does this fit into networking? I think we can all agree that data center networking can change. I’m carefully phrasing that statement by using the word ‘can’. If you don’t know it already, I don’t buy the ‘SDN will change everything you do’ line of thinking. In fact, I try as hard as I can not even to use the term SDN. Why? Because it’s far too vague of a term that can mean almost anything depending on you how you want to interpret it. Beyond being a Continue reading
After a few fat-fingered attempts to get the password entered, i realised I had locked myself out of a new Space installation. There’s only one user at that stage – ‘super’. And now I’ve locked the account. Damn.
To unlock this, you will need to go on the console and enter debug mode. This means you need to know the admin and maintenance mode passwords. Assuming you do, do the following:
mysql> use build_db
Database changed
mysql> select * from USER_IP_ADDRESS;
+--------+--------------+---------------------+--------------+----------+---------+
| id | ipAddress | ipLockedTime | failureCount | isLocked | user_id |
+--------+--------------+---------------------+--------------+----------+---------+
| 229377 | 172.20.45.85 | 2014-06-11 16:29:07 | 0 | 1 | 610 |
+--------+--------------+---------------------+--------------+----------+---------+
1 row in set (0.00 sec)
Update the table to make isLocked 0:
mysql> update USER_IP_ADDRESS set isLocked=0;
Query OK, 1 row affected (0.08 sec)
Rows matched: 1 Changed: 1 Warnings: 0
mysql> select * from USER_IP_ADDRESS;

This post will be the first in a series that examine what I think are some of the powerful security capabilities of the VMware NSX platform and the implications to the data center network architecture. In this post we’ll look at the concepts of Zero Trust (as opposed to Trust Zones), and virtualization-centric grouping (as opposed to network-centric grouping).
Note: Zero Trust as a guiding principle to enterprise wide security is inspired by Forrester’s “Zero Trust Network Architecture”.
We want to be able to secure all traffic in the data center without compromise to performance (user experience) or introducing unmanageable complexity. Most notably the proliferation of East-West traffic; we want to secure traffic between any two VMs, or between any VM and physical host, with the best possible security controls and visibility – per flow, per packet, stateful inspection with policy actions, and detailed logging – in a way that’s both economical to obtain and practical to deploy.
Until now, it hasn’t been possible (much less economically feasible or even practical) to directly connect every virtual machine to its own port on a firewall. Because of this, the Continue reading

I came across this infographic from Anna Vital of Funders and Founders and loved it. As relevant as some of it is, there is an obvious focus on running a startup and not working in IT.
