Intel into Security business!

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Intel the leading chip maker is hoping to step into the arena of security software and services, by acquiring McAfee for $7.68 billion. After the announcement about the deal on Thursday , Intel CEO Paul Otellini said that the deal will give Intel a ‘third pillar’ in computing, to complement its drives for power efficiency and connectivity, in future computing models.


“In the past, energy-efficient performance and connectivity have defined computing requirements. Looking forward, security will join those as a third pillar of what people demand from all computing experiences,” Otellini said in a statement.

“The addition of McAfee products and technologies into the Intel computing portfolio brings us incredibly talented people with a track record of delivering security innovations, products and services that the industry and consumers trust to make connecting to the Internet safer and more secure,” he added.


I am hoping McAfee will reach its new heights at the hands of Intel as these days I feel they are losing their glory.

Cisco WebEX Meet a great tool for web conferencing

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

We all know the importance of WebEx these days; especially it’s widely used by Cisco TAC team to solve your TAC tickets. At least I have encountered this lot. In fact these days our Organization is setting up most of our meetings using Cisco WebEx, a powerful technology which even works well at a limited bandwidth.  Now imagine yourself having a web conferencing solution similar to Cisco WebEx– but for free! Yes you can, you don;t need to just imagine but  also can experience it. Thanks to Cisco Systems for their WebEx Meet. Which is currently in its beta form and its available for free, though it’s not as rich as Cisco WebEx when it comes to features, but an awesome technology to use.

The Cisco WebEx Meet is ideal for giving a presentation or viewing a client’s desktop or even recording a meeting. At maximum you can setup the WebEx meeting with four people which is good for small and mid-size organizations even it can used for family meetings as well. I tried to setup a trail meeting which proved to be a successful one,  the quality of video was of a high and  also I had the privilege of sharing documents and applications with my peers.

Still in its early stage, but still I can predict a great success for Cisco WebEx Meet which can surely meet the bigger demands for smaller and mid-sized companies who cannot afford to buy complex, integrated Web conferencing solutions.  For more info do visit the Cisco WebEx site and start trying Web EX meet for free as the service is still in beta.

Microsoft and Polycom are entering into an alliance to Enhance Unified Communications and Collaboration Solutions

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

As technology is evolving the importance of Unified Communications is growing, yet until now I thought Cisco is a leader when it comes to Unified Communication especially after the introductions of Tele presence and WebEX, but others vendors too are competing hard. Avaya took over Nortel when it was in crises, to enhance its product line. Now its Microsoft and Polycom are entering into an alliance, which provides an opportunity for them to jointly develop, sell and market Unified Communication products based Polycom endpoints and Microsoft Communication Server 14.

Polycom’s solutions for Microsoft Communications Server 14  will span markets ranging from the enterprise, to small and medium-sized businesses, to governments, the statement said. The promised integration aims to help bring Microsoft’s UC product together with Polycom’s conferencing tools, which the companies said over time will make the two systems easier for IT and telecommunications staff to manage.

“Microsoft and Polycom solutions play a critical role within our current and future unified communications strategy,” said Martin Smale, IT director at NDS, a News Corp. company. “We’re already benefiting from improved collaboration, increased productivity, and significant ROI based on our existing UC network, and we’re looking forward to leveraging the expanded offerings from two of our most valued vendors in the UC space.”

“Our research shows that nearly 70 percent of the companies considering a unified communications solution are thinking of deploying Microsoft Office Communications Server,” said Brent Kelly, senior analyst and partner at Wainhouse Research. “These enterprises need seamless integration and interoperability between Office Communicator on the desktop and personal, group, and telepresence video solutions like those offered by Polycom for executive offices, meeting suites, and conference rooms. By working together, Microsoft and Polycom are making it easier for organizations to have a true end-to-end unified communications environment, which includes high definition video.”


For further details on the alliance have a look at the press release from Microsoft.

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

The ongoing collaboration between Cisco Systems, NetApp and VMware is proving fruitful and their amicable collobration has resulted in inducstry’s first certified end-to-end Fiber Channel over Ethernet(FCoE) solution for VMware-virtual environments.

The combined solution resulted in supporting FCoE end-to-end to reduce the number of devices and cables needed to drive data center consolidation, virtualization, and automation. Cisco data center switches and NetApp storage FCoE solutions are now validated by VMware to support VMware-based virtualized environments, marking a significant milestone for the progression of the FCoE protocol to help more customers achieve efficiency in their dynamic data centers and progress on their journey to cloud computing.

Cisco Systems, NetApp and VMware are currently the only networking, storage, and virtualization vendors to combine data center consolidation, virtualization, and automation in a jointly certified end-to-end FCoE solution that includes both FCoE initiators (such as Converged Network Adaptors) and FCoE storage targets. VMware validated Cisco Nexus® 5000 Series Switches and NetApp FAS series unified storage support FCoE protocol in virtual environments running VMware vSphereTM.

How to use a Cisco Router or a Cisco Switch to decrypt the encrypted passwords (type 7 passwords)

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Normally we use any of decrypting software’s to decrypt the Cisco type 7 passwords, which were encrypted by using a Cisco IOS command “service password-encryption”.  Image you don’t have an access to the internet or you don’t have a Cisco password decrypting software’s, what you will do in this situation. No worries you can use the Cisco Router or a Cisco Switch itself to decrypt the Cisco type 7 passwords.  Amazing isn’t it! We can make use of a feature call “key chain” to decrypt the encrypted type 7 passwords. To demonstrate I am just creating a scenario

Step 1

Create a username in your Cisco device and encrypt the password  by using following commands

ITKE-AS01(config)#username itke password joinitke

ITKE-AS01(config)# service password-encryption


Step 2

Let’s see user name and password we created

ITKE-AS01#sho run | include username

username itke password 7 12130A1E1C02180F2F



We can see “7 12130A1E1C02180F2F” is the encrypted password for joinitke which we created in step 1.

Step 3

Now we need to create a key chain and copy the encrypted password as the key string as demonstrated below

ITKE-AS01(config)#key chain getpassword

ITKE-AS01(config-keychain)#key 1

ITKE-AS01(config-keychain-key)#key-string 7 12130A1E1C02180F2F


Step 4

Now we can see the decrypted password by using the Cisco IOS command “show key chain getpassword”

ITKE-AS01#show key chain getpassword

Key-chain getpassword:

    key 1 — text “joinitke”

        accept lifetime (always valid) – (always valid) [valid now]

        send lifetime (always valid) – (always valid) [valid now]


Amazing we can use a Cisco Router or a Cisco Catalyst Switch to decrypt the type 7 encrypted passwords. Use this and do let me know.
