BrandPost: Beyond the Firewall – Different Rules for East-West Traffic

Network firewalls were created to block unauthorized content and code from the network while ensuring the unimpeded flow of data packets vital to the operations of the enterprise. But they were designed to intercept external incursion, not prevent security issues inside the network.“As server virtualization has increased in popularity, the amount of traffic moving laterally across the data center (East-West) has dwarfed traditional client-server traffic, which moves in and out (North-South),” industry analyst Zeus Kerravala writes in Network World. “This is playing havoc with data center managers as they attempt to meet the demands of this era of IT.”To read this article in full, please click here

Ideas this bad could kill the Internet of Things

What’s the silliest, dumbest, most ridiculous Internet of Things (IoT) application you can think of? Smart toothbrushes? Internet-connected toilets? Digital notepads in the shower?Well, forget all that. Heck, you can even forget the "smart" Air Dresser wardrobe that Samsung announced earlier this month. (If you’re wondering, this digital closet is said to automatically "air" — whatever that means — steam, dry, and purify clothes so they don’t, you know, stink.)IBM has just patented an IoT device concept so incredibly inane that it makes all those earlier attempts to trivialize the IoT seem like cures for cancer. What could possibly be so ill-conceived as to make a smart hairbrush look, well, smart?To read this article in full, please click here

It Is a Challenging Time for the Internet: We Must Not Let It Be Undermined

On 1 September I start work as CEO of the Internet Society. I have a lot to do to live up to the example set by Kathy Brown with all that she achieved during her leadership. It is a great honour, and I appreciate the trust the Board of Trustees has placed in me. I will work daily to earn the same trust from the rest of the Internet community, in part by being transparent about what drives me to do this.

It is a challenging time for the Internet Society, because it is a challenging time for the Internet. For most of the Internet Society’s history, the expansion and development of the Internet could be regarded as an obvious good. There were always those who simply opposed technological development. There were always those who wanted their own interests protected from the Internet. But Internet users historically benefited so much, so obviously, that skepticism about the value of the Internet itself was rare.

Things have changed. Every technology can be used for negative ends. The Internet still, plainly, brings gains in efficiency, convenience, and communications. Yet in the recent past, some of the negative uses have become apparent, which leads Continue reading

Openswitch OPX in GNS3

The previous article discusses an installation of Openswitch OPX on VirtualBox using lvm tool. We have extracted Openswitch OPX VDI disk from VirtualBoxVM and run the disk with Qemu. The image has been subsequently customized using the after install script in order to run it inside GNS3. Finally, we have tested the image within a simple GNS3 lab that proves its functionality. This article goes further and we are going to test VLANs bridging using Linux native commands.

Picture 1 - Network Topology

The lab consists of three Openswitch OPX 2.3.2 instances powered by Qemu hypervisor. The device OPX-Distrib1 is multilayer switch that is responsible for routing between VLANs 10,20,30,40 and 50. The VLANs 10-40 are end-users VLANs and the VLAN50 is used for management. The switches OPX-Access1 and OPX-Access2 are L2 switches with the port e101-001-0 configured as the trunk ports. End users are connected to the access ports e101-002-0 and e101-003-0 on both access switches.

Note: Customized Openswitch OPX 2.3.3 vdi disk can be downloaded in Download section. Login name is opxUser and the password is not set.
