Every professional must have faced a dilemma at least once in their life where they are not recruited because they don’t have work experience. How can they get Work experience until they are recruited once? Thanks to simulations, folks who are in IT can at least work on a simulation of what they expect at work place. For those who intend to get into networking, there are simulations available which can simulate networks with real operating systems. For those who intend to get into Linux server administrations, Simulations are not exactly required as almost anyone can install Linux on a system or dual boot your laptop or desktop. There are still cases where you don’t want to install Linux on your working system or there is no system to install Linux on. Thank God for Raspberry Pi, a computer is in everyones reach now.
It has been more than 10 years I have been using Hotmail and the one feature I have been yearning for was IMAP on Hotmail (now outlook.com). Every other web based email provider has it, Yahoo has it, Google has it but my primary mail has always been hotmail. I have lost more than 5 years of mails just because while configuring email with POP Protocol, the mail client was set to download messages from the server. There was no way of putting the mail back to the server once downloaded and there was no economically feasible way to take a backup of the mails back then. Also, there is the other problem of deleting and moving mails on your Laptop as well as doing the same on the Web Mail. With a recent announcement from Microsoft, Outlook.com has begun supporting IMAP protocol. With this, we can configure the Mac mail with IMAP and enjoy the beauty of IMAP with Hotmail.

21st Century is all about technology. With the advent of ip networks in the end of last century, all the technologies of yesteryear is being integrated with ip so that the concept of location has blurred. A person living in India can work for a US company. A person sitting in the office can control his home electronics. Data has gone online so that it is accessible from anywhere.
In this blog, we will look into everything related to technology. I have always been interested in technology since my childhood and thus took up Engineering Studies from Mumbai University. I have built my career around computer networking technology. I am always interested in Computers and Technology and that makes me delve deeper into the subject.
If there is any post you need clarification on or there is some content you would like me to write about, please feel free to contact me.

The integration of Virtualbox with GNS3 has driven me crazy as simulations you can do with it are limitless. When QoS over MPLS is concerned, not many websites are available explaining it in simple terms. The vast majority of results you might get on google would refer to Cisco documentations. It gives me chills to refer to Cisco documentations as it is just too vast and the thought of it overwhelms me. So in this blog, we will see how QoS works in an MPLS environment and the various types and options available with it. We will make a vanilla MPLS setup so that we can concentrate more on QoS.

With the addition of Virtualbox to GNS3, you can do all sorts of simulations (except full switching) involving routers, firewalls, servers (windows or linux), applications, etc. It used to bother me a lot to run a network topology and rely on ping and tftp as test traffic for QOS. Now you do not have to rely on boring traffic to test QOS. You can use actual user traffic and classify and mark it on your routers to give it preferential treatment. You can set bandwidth caps on certain protocols, you can prioritise certain protocols, you can remark certain protocols, etc. The options for QOS testing are limited by your imagination.
In this blog, we will cover basic user traffic like web, ftp and windows sharing and classifying them to mark for QOS treatment. We will rate limit some, prioritise some and remark some on our network and see its effects on the destination end. We can also use the relevant show commands to verify proper operations.

Since the time NAS drives became cheaper, it has found its way in homes and small offices. Manufacturers have come up with ingenious uses for it which was not possible before. NAS drives have become computers on their own with their own OS and can replace a PC in many cases. NAS drives can be used for File sharing thus eliminating the need for a PC to be on 24×7. NAS drives can be used for downloading via Torrents thus eliminating a PC to be ON throughout night. NAS drives can be used for hosting simple Web servers. NAS drives can be used as a Media Server hosting and sharing Media throughout the home via DLNA. There are some NAS drives which can host a USB Printer thus eliminating the need for a PC to be ON for sharing printers. You can make your private cloud with NAS drives. Since NAS Drives are generally of larger capacities, they are used for backup of important data. Thanks to Time Machine support, NAS drive can backup data from all Mac computers at home without the need of a USB hard drive. Also, since you are already part of the network, there is no need to do any physical connecting and disconnecting of peripherals.
Many people are aware of NAS drive as a Network backup device but they are not aware that one NAS drive can take backup from multiple Macs. Since Apple fans stick with Apple products, it is quite common for one home to have multiple Mac computers. Continue reading
We are living in a world where everything is becoming wireless with Megabit and Gigabit speeds. These days even Power is transferred to a Smartphone wirelessly via Qi charging. There are some things which are wireless but their speed is pathetically slow to be of much use these days. The technology in particular is Bluetooth. Bluetooth has a theoretical bandwidth of 3 Mbps which is insufficient for our Media Transfer requirements. These days the image files being generated by the 10+ Megapixel camera is easily above an MB and the recording of a 1 minute HD/Full HD video easily goes above 100 MB. In order to transfer these large files to a laptop would take an hour over Bluetooth. The question here is “Can we not transfer these files via the USB cable?”. Yes we can but it kills me to do that because when everything has become so seamless, so why can’t we transfer files seamlessly? Continue reading
This is a continuation to my previous Blog “Media Centre for Your Connected Home”. In that Blog, I covered the concept of a Connected Home. In this Blog, I will cover the setting up of the Media Centre. TV forms an integral part of our home entertainment and we desire to have the best TV. Over the years, TVs have gone smarter with support for online streaming like Youtube, Hulu, Netflix, Dailymotion, etc. It also supports playing Media files stored on your computer, Smart Phone or Network hard drive. There are even some TVs which have applications for Skype, facebook, Web browser, etc. Many people these days have TVs which have large screen with good display but they do not have the above mentioned features and it does not make sense to throw away the TV and get new a one just so that you can watch online streams or view your personal media content. This is where Raspbmc comes into the picture. Raspbmc is a device which allows you to do most of the above on your conventional TV. Raspbmc is a Raspberry Pi computer running the XBMC software. It can be set up for less than $50. Continue reading
A technology blog cannot be complete unless every aspect of Technology is covered. This includes keeping your Tech devices neat and clean. Those folks who own White Macbook or Apple Keyboard might be more obliged to keep it clean as over time the white products become brown. Some while back I thought of using Mr. Clean Magic Eraser but due to its high price and unavailability in India, I had to shelve the plan. Even if I had acquired it by some means, I would have been very reluctant to use it as there were many people on the Internet who advised to restrain precaution while using it since it was very powerful. One wrong stroke and the text on your keys could be wiped off or the surface of the Macbook could get scratched. Continue reading
These days owning a Smart phone has become almost a must. On top of that there are those who have the urge to have the latest and greatest model. This as well as other reasons are there for quite a lot of old spare phones which are just lying at home without any use. There have been a lot of articles written about how to use these phones. Some are just silly yet useful like using it like a torch. Some are sensible like using it as a music player so that your current phone does not drain battery. Some are downright geeky like using the phone for opening a garage door. I am going to take middle ground and write about what I think is sensible use of the spare smart phone. Continue reading
