For the last 20 years, a “silicon moat” that has protected Cisco and other networking vendors from market competition. Arista was one of the first startups to embrace merchant silicon,open source software and a modern software development methodology to focus on core value like reliability and features.

HP Discover is happening this week and have three announcements that I'm summarising here. They are Virtual Cloud Network (VCN), FlexFabric 7900 switch and a supporting package of consulting to implement cloud in your organisation.
The post Briefing: HP Helion, Virtual Cloud Networking, FlexFabric 7900, SDN and OpenStack at HP Discover appeared first on EtherealMind.
For best article visual quality, open Introduction and LAB tutorial of HP Helion Community Edition, the OpenStack based “cloud” system that can give you a personal cloud! directly at NetworkGeekStuff.
Hewlett-Packard (HP) is a long enterprise supporter of cloud technologies and early this year, they released publicly HP Helion Community Edition (CE). HP Helion is HP’s OpenStack based cloud system with which HP plans to provide value added services (both in sense of software and service) with the upcoming release of HP Helion Enterprise edition later this year. In this article, I plan to introduce you to the HP Helion CE, quickly guide you through the installation, basic operations and in the end get you a quick view on the OpenStack architecture in general.
For a long time HP has been providing cloud solution based on their internal Cloud Service Automation or “CSA” system to enterprise grade customers as part of their portfolio. I had access to several projects using this environment and although I still have mixed feelings about their effectiveness, they were a step in the right direction as classical (now called “legacy”) data-centers are loosing popularity to cloud and other automated systems.

Since publication of the Etumbot blog on Friday, June 6th, we’ve received numerous requests to publish Snort rules for the network indicators described therein. You can find Snort rules for the Etumbot C&C communications on Arbor’s github at
https://github.com/arbor/snort/blob/master/etumbot.rules
While we are not Snort syntax experts, we have performed basic testing for the Etumbot communications we’ve been able to observe over the wire. Specifically, the first three Snort rules for Etumbot RC4 Key Request, Etumbot Registration Request, and EtumBot Ping all triggered successfully when the corresponding network traffic was observed.
Remember to change the SIDs as appropriate for your environment. We also anticipate these rules will be incorporated into the EmergingThreats Open feed in the very near term.

Pluribus Networks has a unique approach to Software Defined Networking that turns a network switch into a server and application platform. In this sponsored show, Sunay Tripathi deep dives into Netvisor and explains how it can fit into your network architecture.

For best article visual quality, open [minipost] Mikrotik/RouterBoard port-knocking example for firewall/NAT openings directly at NetworkGeekStuff.
The situation is very simple, you are away from home (imagine visiting a friend or being at work), but you desperately would like to access your internal LAN FTP/Samba/etc… , but you do not have with you your own notebook or any device with a VPN capability to tunnel to your home securely. So what to do ? You do not really want to open your home firewall and NAT whole internet to the internal PC or server on your LAN. Lucky for you, there exists a trick under a name of “port-knocking” where you can send to your home firewall a sequence of TCP or UDP packets with specific ports (the ports act as a password) and your home system can temporarily open the firewall and NAT to only your source IP from which these packets arrived. In this quick example I will show you how to do this on Mikrotik (where I do this for several years now) and I will point you to generic linux tutorial for the same using iptables in links below.

In this transcript from Seeking Alpha, Gary Moore, Chief Operating Office of Cisco claims that " eight of the global ten over-the-top providers like Amazon are huge Cisco customers". For network architect & strategy types, it's worth reading to see how Cisco intends to extract more revenue from your budget. In particular there are several references to Cisco "analytics service offerings" which Mr Moore states are opportunities for upsell in SmartNet maintenance. It might be worth looking into those products to prepare a "defense against the dark arts" from Cisco account managers.

Glue Networks had a presence at the last ONUG, where Tom Hollingworth was able to get an overview from Glue’s founder, Jeff Gray:
As you can see, Glue’s product targets the WAN, and specifically addresses the difficult provisioning tasks that most shops do manually. These include but are not limited to:
Jeff visited our Tech Field Day round table at ONUG 2014 and gave us a more detailed introduction to the product:
First, some things I think this product does (or will do) well. The configuration of PfR or QoS en masse is a low-hanging use case I’ve mentioned before and even if I can do it using scripts today, having a single tool that does it in a simple way will provide value. These specific configurations are difficult and error-prone, so anything that tackles this is going to be useful.
I also did enjoy hearing about the options for getting the config onto the device. Jeff listed three options for Continue reading
The Arbor Security Engineering Response Team (ASERT) has released a research paper concerning the Etumbot malware.
Etumbot is a backdoor used in targeted attacks since at least March 2011. Indicators suggest that Etumbot is associated with the Numbered Panda group, also known as IXEHSE, DynCalc, and APT12. Although previous research has covered related malware, little has been publicly discussed regarding Etumbot’s capabilities.
Indicators suggest that the Etumbot dropper is delivered via spear phishing and is contained inside an archive file intended to be of interest to the target. The attackers use the Unicode Right to Left Override technique and document icons to disguise malicious executable content as document files. Once the dropper is executed, the backdoor is activated and a distraction file of interest to the target is opened for viewing. ASERT has observed several Etumbot samples using distraction documents involving Taiwanese and Japanese topics of interest, and has also observed recent development activity which indicates that attack campaigns are ongoing.
Once installed, the backdoor connects to it’s Command & Control server and receives an encryption key. RC4 encryption, along with HTTP transactions intended to blend in with typical traffic are used for backdoor communications. Etumbot’s core functionality Continue reading
