SearchITChannel: Is bimodal IT the future of the channel?
By John Moore
CHICAGO — In CIO circles, bimodal IT has been a conversation starter: How can an enterprise’s information leadership balance the necessity of keeping the lights on against the challenge of adopting emerging, business-changing technologies? That same discussion is now surfacing in the channel. Speakers at this week’s CompTIA ChannelCon 2015 here suggested the possibility of partners becoming bimodal and the Continue reading
The Core Linux is a small modular Linux distribution that provides only a command line interface and tools that allows you to build your own application extensions. Thanks to these extensions you can easily turn your Core installation to a custom appliance such as network host, router, switch, server. Moreover choosing the Core Linux as an operating system for your appliance significantly reduces the size of the appliance.
Two weeks ago I started to build a network host that can handle network traffic. I installed the latest 64 bit Linux Core 6.3 on VMware virtual disk and loaded Core with extensions that can generate traffic, measure bandwidth, route, forward and filter traffic. A list of the extensions, their purpose and configuration changes is mentioned here.
I share my own network host VMware disk in Linux Core download section. You can create a new virtual machine (VirtualBox, VMware Workstation/Player, Qemu) with the disk attached and use it in your GNS3 labs in order to simulate network host. The disk contains the following tcz extensions:
bash - 4.3.39(1) with patches up to 39
bash-completion - 2.1
d-itg - 2.8.1-r1023
hping3 - 3.0.0-alpha-1
iperf3 - 3.1b3
iproute2 - 3.14.0

An increasingly apparent and large challenge in IT organizations is how teams can effectively modernize software development and IT operations while still operating and maintaining legacy infrastructure. Often the approach is to merely draw a line in the sand, creating an arbitrary cut-off whereby new implementations make use of the much desired DevOps and Agile methodology.
But what about the legacy environments?
Just because something is “legacy” doesn’t automatically mean that it’s twenty years old. Many so-called legacy systems were deployed mere months ago-- and on modern hardware, operating systems, and storage. For the sake of an agile organization, however, a legacy deployment or environment is anything that is not included in the new processes and approaches required for a DevOps-enabled organization.
The question remains: how can IT organizations successfully apply DevOps and Agile methodologies to existing legacy environments, and what are the benefits from doing this?
Regardless of the type and variety of applications in an enterprise IT environment, there are likely many commonalities in the operating system and infrastructure components.
Manual OS build processes typically require significant admin-hours to deliver a single build. Additionally, the reliability of the result is a totally dependent Continue reading

MERRILLVILLE, Ind. – Networking engineers in all industrial sectors who are preparing to take the Cisco Certified Internetwork Expert (CCIE) exam may benefit from a Purdue Research Park tenant that offers products and monthly preparation courses.
iPexpert Inc. is a tenant in the Purdue Research Park of Northwest Indiana that helps its clients prepare to take the CCIE Collaboration certification exam. Andy Vassar, senior technical instructor, said the prep courses are suitable for all networking professionals.
“Today, almost every company will have a networking engineer design and implement computer networks, and almost everyone runs Cisco Systems equipment in their network,” he said. “A CCIE certification is the most respected, sought-after certification in networking and there are many opportunities to use it. Those who earn it are considered the top experts in their profession.”
CCIE certification is available on several subjects including Routing and Switching, Data Center, Wireless and Security. Vassar said iPexpert classes at the Purdue Research Park of Northwest Indiana prepare attendees for the CCIE Collaboration certification, which covers communication via telephone, instant messenger and video.
“CCIE certification exams have two parts: passing the two-hour written test makes you eligible to take the eight-hour lab exam,” he said. Continue reading
