Yasir Irfan Yasir Irfan Profile: Yasir Irfan

HP has agreed to its plans to buy router and switching gear maker 3Com for $2.7 billion. This deal will see HP expands its infrastructure portfolio range with 3Com’s routers, Switches and Security products as well it will strengthen the HP position in China thanks to 3Com’s strong presence in China. The transaction is expected to close in the first half of 2010.
The transaction has been sealed at US$7.90 per 3Com share and is yet another example of an acquisition that will present significant competition for Cisco in the networking market, particularly in the data centre space and network convergence.
“Companies are looking for ways to break free from the business limitations imposed by a networking paradigm that has been dominated by a single vendor,” said Dave Donatelli, executive vice president and general manager, enterprise servers and networking at HP, in a statement issued by the vendor.
“By acquiring 3Com, we are accelerating the execution of our converged infrastructure strategy and bringing disruptive change to the networking industry. By combining HP ProCurve offerings with 3Com’s extensive set of solutions, we will enable customers to build a next-generation network infrastructure that supports customer needs from the edge of the network to the heart of the data centre,” he added.
HP points out that the purchase of 3Com will bring strong security capabilities through the vendor’s TippingPoint portfolio. It also states that thanks to extensive testing of 3Com products, it is planning to complete the global roll-out within HP soon after completion of the acquisition.
Let’s see how successful this acquisition will be in terms of capturing the market share from the lead player like Cisco Systems.

How to configure Secure Copy (SCP) in Cisco Devices?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

In my previous post I was talking about the Secure Copy (SCP) what is it?  , now let’s see how to configure Secure Copy (SCP) in a Cisco Router or a Switch.

In order to configure Secure Copy (SCP) in a Cisco Router make sure the SSH is enabled and its working.

Step 1) Lets enable the SSH and AAA features in the Cisco Device


ITKE-AS1(config)#ip domain-name

ITKE-AS1(config)#crypto key generate rsa general-keys modulus 512

The name for the keys will be:


% The key modulus size is 512 bits

% Generating 512 bit RSA keys, keys will be non-exportable…[OK]



ITKE-AS1(config)#aaa new-model

ITKE-AS1(config)#aaa authentication login default local

ITKE-AS1(config)#aaa authentication exec default local


Step 2) In order to use the SCP feature to manage configuration we must have at least once user account with enough privilege to access it


ITKE-AS1(config)#username itke privilege 15 password secret itkeleads


Step 3) Now you are ready to enable the SCP server on:

ITKE-AS1(config)#ip scp server enable



Just by following these 3 simple steps we can enable Secure Copy (SCP) in a Cisco router or a Switch. For any further clarifications you can always have a close look at Cisco’s document on Secure Copy (SCP).

Fortinet October ’09 Threatscape Report Shows Highest Malware Levels Detected all Year

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

According to the latest Threatscape report (October 2009) released by Fortinet, the total amount of malware detected is more than a year, with levels four times greater than in the previous month (September 2009).

The two main Bredolab variants detected this month were W32/Bredo.G and W32/Bredolab.X, most notably included in fake DHL invoice spam campaigns.

Derek Manky, project manager, cyber security and threat research, Fortinet commented: “We’re seeing record levels of scareware building off volume from September, and the danger in these threats is only becoming more serious as the methods for delivery evolve and the blending of attacks bring more complexity.
“As we’ve seen in the consistency of repeated threats, the old schemes are still proving to be good methods. Enterprises and consumers must take equal responsibility in understanding the disguises of these threats and implementing a multi-pronged security solution that addresses the different and changing characteristics of tried and true tactics,” he added

During the month of October 2009 Scareware tactics have reached all time high, with worst ever attacks reported. Seven of the top ten malware variants detected linked back to scareware, with scareware tactics diverging to include botnets, corrupted advertisements and SEO attacks.

The most notable development in October 2009 was the preponderance of AntiVirus Pro 2010 rogue security software, which when installed will contact a remote server in order to obtain malicious payload and receive updated copies; a trojan downloader named Bredolab which is now downloading AntiVirus Pro 2010 installers and the ZBot keylogger; and the ongoing development of affiliate programs that tempt participants with a handsome pay-out on each software download purchased. Tools and kits are readily available to participating affiliates, accelerating the distribution of scareware and other malicious components.

What is Secure Copy (SCP)?

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


We are all aware of the traditional way of transferring IOS files from and to Cisco Catalyst Switches, Cisco Routers and Cisco PIX/ASA firewall devices using TFPT, FTP and lately https. However there is also one more way to copy the IOS files, which is known as Secure Copy (SCP). The Secure Copy (SCP) is a secure and authenticated method of copying a configuration file or transferring an Image files to Cisco Catalyst Switches, Cisco Routers and Cisco PIX/ASA firewall devices.


Cisco Systems introduced the Secure Copy (SCP) feature in the following IOS releases





This feature was introduced.


This feature was integrated into Cisco IOS 12.0(21)S.


This feature was integrated into Cisco IOS 12.2(25)S.

PIX/ASA firewalls 7.1 and above, FWSM 3.1 and above.


The Secure Copy (SCP) works on SSH protocol on port 22 which is like an encrypted tunnel. This tool is very useful especially to transfer files for upgrades or to perform safe backups.


In my next post you will find the commands to configure SCP in a Cisco Router and Switch.

CCIE Routing and Switching Official Certification Guide to be released in November 2009

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

I was just accessing the rough cuts for the Cisco CCIE Routing and Switching Official Certification Guide, 4th Edition. I had a great first impression. I had a chance to read “LAN Switching” part. It was a great firsthand experience. This segment is organized well and the approach is similar to CCNA, CCNP books, starts with a brief introduction and then the most useful section of Cisco Press Books “Do I Know This Already?” Quiz followed by “Foundation topics and “Foundation Summary”.


Pic Courtesy: Cisco Press


The Cisco Press authors Wendell Odom, Rus Healy and Denise Donohue did a credible job; I liked the way they presented the topics, since I spent most of my time on Switching I really enjoyed the “LAN Switching” part. Though I am familiar with most of the things they were talking but it was great experience to refresh my info.


The CCIE Routing and Switching Official Certification Guide 4th Edition is to be released on 19th of November 2009 by Cisco Press, they are offering great discount do check Cisco Press web site for more details, but make sure you registered yourself to Cisco Press website to get more discount. Once the book released I will try to write a review on this book.

Windows 7 is amazing in terms of Systems restoration

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

I am using Windows 7, since beta days and then now with RC release.  Couple of week’s back I was attending a Seminar “Introducing Windows 7” organized by Microsoft for their partners. I did asked few questions; one of them was related to Windows restore and hibernation. I asked them if I have a complete Backup of my computer in my external USB hard disk, is it possible to restore Windows 7 and all applications in a new hard disk. The gentleman said it’s not possible. I was not convinced thought of testing myself.

 First using the Systems and Security menu from Control panel I selected the option “Backup your Computer” and I selected I created a System Image in my External USB hard disk.


Then I created a System repair disk by using the menu “Create a system repair disk” from the Systems and Security menu from Control panel.


Once I am done with these things I replaced the existing hard disk in my laptop with a new one. Then I installed Windows 7 in my laptop, after completion of Windows 7 installation I restarted my laptop with the restore disk I created and I made sure my External USB hard disk is connected my laptop as well. I booted the laptop using the System repair disk and then I click next once I got this menu,


And then I selected the option “Restore your computer using a system image that you created earlier”

Then I selected the latest available system image which by default selected the image stored in my external USB hard disk,

 If by change if the latest system image is not shown you always have an option to select the image manually. Once I selected the image file stored in my external USB hard disk I was able to restore my laptop with all applications and documents stored in my original hard disk. Cool utility that too GUI from Microsoft in Windows 7. For some reason I forget to take the backup of my contacts in my Microsoft Outlook 2007 so again I removed the new hard disk and replaced it with the original one. When I restarted the laptop with the original hard disk, the laptop started back from the Hibernation mode. As I forget to shutdown my laptop before starting this whole operation. It was hibernated with lot of open files and windows. Amazing isn’t it.

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

Yet another acquisition is planned by Cisco Systems. Cisco Systems is planning to buy advance wireless telecommunication equipment makers Starent Networks Corp for 2.9 billion dollars to boost its product offerings as phone carriers build out next-generation networks. This will be a second major acquisition this month for Cisco Systems after billion buyout of videoconferencing leader Tandberg for roughly 3 billion dollars.

According to a post in Cisco blogs, by acquiring Starent Networks CorpCisco Systems can expand their product portfolio in mobile internet market. As we all know the Emerging markets are seeing the success of Wi-Max technology. Surely this acquisition will help Cisco to broaden its presence in the Wi-Max area.

“The growth of smart mobile devices and net books has fundamentally changed consumer behavior with regards to how they use the Internet,” said Ned Hooper, Cisco’s chief strategy officer who also oversees the consumer business.

By first half of year 2010, the acquisition is expected to close. Until then Cisco Systems and Starent Networks Corp  will continue to operate as separate companies. Upon completion of the transaction Starent Networks Corp will become the new Mobile Internet Technology Group led by Starent President and CEO Ashraf Dahod. Starent was founded in 2000 and completed its initial public offering in 2007. The company is based in Tewksbury, Mass., and has approximately 1,000 employees worldwide.
