CPU hardware information The cpu information includes details about the processor, like the architecture, vendor name, model, number of cores, speed of each core etc. There are quite a few commands on linux to get those details about the cpu hardware, and here is a brief about some of the commands. 1. /proc/cpuinfo The...
Secure copy Scp (Secure Copy) is a command line tool to copy or transfer files across hosts. It uses the same kind of security mechanism like the ssh program. Infact it uses an ssh connection in the background to perform the file transfer. scp refers both to the "protocol" that defines how secure copy should work and the "program" (command) which is installed as a part of OpenSSH suite of tools. In this quick tutorial we shall look at a few examples the scp command and how it can be...

As a Linux sysadmin it feels great power when monitoring system resources like cpu, memory on the commandline. To peek inside the system is a good habit here atleast, because that's one way of driving your Linux system safe. Plenty of tools like Htop, Nmon, Collectl, top and iotop etc help you accomplish the task. Today lets try another tool called Glances. Glances Glances is a tool similar to that has a very compact display to provide a complete overview of different system resources on just...
I recently read that SSH keys provide a secure way of logging into a Linux and Unix-based server. How do I set up SSH keys on a Linux or Unix based systems? In SSH for Linux/Unix, how do I set up public key authentication?

Before rolling out the analysis, it’s important to understand the technology. Microsoft Lync 2013 helps connect to multiple people across different operating systems and mobile devices. As a unified enterprise-ready communications platform, it enables an environment that facilitates instant video conferencing, messaging, voice chats and meeting. In short, it provides a single and consistent presence experience for its client.
While Microsoft may project changes brought about in the Lync Server 2013, enabling better experiences than ever before, there are a few concern areas that you users need to be aware of.
- Video Conferencing limitations: Continuing to be a low area, this version of Microsoft’s Lync too has been observed to be immature in terms of its video conferencing capabilities. Besides, it doesn’t provide end-to-end solutions such as video-room systems, video desktops, telepresence systems or video gateways. Its solutions for multi-party video conferencing, works on desktops only. Its conferencing capabilities are also limited with allowing a maximum of five people in a conference only and feature lacks such as server-side recording, dual presentation and multi-casting. Other problems associated with its video conferencing capabilities are its interoperability constraints with 3rd party products and that it consumes exorbitant bandwidths which are about 600% more than its counterparts.
- ü Lack of consistent BYOD support: BYOD is the next big revolution that’s happening in working environments. As such Lync 2013’s compatibility with the BYOD culture is critical. While it does support presence and instant messaging on platforms like iOS, Android and Windows, it falls short of features like simultaneous multi-party video and viewing shared meeting content.
- ü Voice limitations persist: This was one of the major lookout areas in terms of improvements expected. To begin with, users will have to invest in conference phones, Session Border Controllers for security purposes and 3rd party gateways. If you have a pre-existent system in place, you actually have to rip it apart. Besides it doesn’t even have call recording, call parking or contact centre features, making it troublesome for most users.
- ü Real-time collaboration shortcomings: Microsoft’s Lync 2013 requires sourcing a number of applications from various 3rd party vendors, making it unsuitable for users looking for an all-in-one solution.
- ü Investments in trainings: Due its nature of complexities, organizations will need to invest in training their staff, in-mates. Besides, they will also have to hire individuals with Linux certifications to help deploy and manage the system and troubleshoot as and when required. All this requires huge investments that organization may want to reconsider beforehand.
- ü Investments in Lync Voice too high: As per the conclusions from detailed interviews done with 211 real world customers, it was observed that Lync’s users spent $1,912 on an average, in installations (on the 1st year itself).
- ü Customer Choice is limited: Essentially Microsoft’s way with its products and sales strategies, for instance, product bundling, can end up in users being locked into their systems.
For the perfect communications solution, organizations require services that can be imbibed into existing systems, with delivering effective and efficient quality services in a cost-effective structure.

Unless you have no life, don't watch the news, and don't care about others snooping around your secrets, you are well aware that these days the government's favorite activity is spying and monitoring their people from all sides, by all means, with no scruples and no remorse, possibly including yourself.
Even if you do have a life, do watch the news, and do care about others snooping around your secrets, you certainly use one of those free popular e-mail accounts that boast of their awesome unlimited features without realizing that they are the ones that are secretly stabbing you on the back and violating your privacy.
It was because of such things that our team wrote a book on advanced e-mail security with cryptography and we want to share it with you. In this book you'll get the following benefits:
- Awareness: you will understand how things work and never be fooled again.
- Privacy: no one will spy your e-mails anymore, your communications will remain private.
- Security: if your e-mails ever get compromised, no one will be able to decipher and read them.
- Credibility: you will demonstrate to others how much you care about your privacy and your security, as well as theirs.
- Flexibility: the system can be implemented anywhere, from home to business to mobile devices.
- Power: high level military grade cryptography being developed for more than 15 years.
- Freedom: 100% free/libre software based on an open standard, open source, no spyware, no malware, no viruses, nothing.
- Cost: completely free - gratis - you won't have to buy or pay for any software.
The book is short, full of images and graphics and easy to understand. It was written for laypersons, so anyone can follow it and do the required steps very easily.
And how about the price? Well you'll love that part: you can get and share the book for free, no hidden fees or registration required, you pay how much you want for it. That's it, that's how we work, you only pay if you like.
If you like it we suggest a contribution of $10.00, the price of a decent cappuccino cup. We put a lot of effort to write it and it took a long time to be finished, so if you like it we would very much appreciate a $10.00 contribution from you.
