How To Use Netcat to Establish and Test TCP and UDP Connections on a VPS Introduction Linux is known for having a great number of mature, useful command line utilities available out of the box in most distributions. Skilled system administrators can do much of their work using the built-in tools without having to install additional software. Build a Raspberry Pi media center Use your Raspberry Pi as an awesome media portal for listening to music, watching videos, and viewing pictures. As an old-school XBOX modder, the first thing I wanted to do with my PI was turn it into a media portal. XBMC (Xbox Media Center) is an open source front end for Linux that used to only be available for the Xbox. These days, it is now available for PCs, Linux Distros, Boxee boxes, and most importantly Raspberry Pi. I used a special Linux distribution built for the Raspberry Pi to build a media center, Raspmc ( OpenElec is another option ( .
How to Secure and Encrypt Your Web Browsing on Public Networks (with Hamachi and Privoxy) A VPN tool like Hamachi's good for games, which usually don't support proxies, but for web browsing encryption, a SSH tunnel with AES256 encryption and public key authentication is superior, not only in terms of security, but in portability and "less bulky" software. In order to configure a VPN connection, you need Administrator privileges on Windows computers, plus you have to install software. With a SSH connection, all you need is a SOCKS server+SSH client blend (which does not require administrator privileges, though some applications need them for various reasons. Putty does not.), then point your web browsers proxy settings to localhost, and Voila! Done. OpenSSH is the way to go for Mac/Linux users, and can be used on Windows, but it has to be through Cygwin (which I personally find extremely annoying to use/setup (cygwin)).

Critical crypto bug in OpenSSL opens two-thirds of the Web to eavesdropping For a more detailed analysis of this catastrophic bug, see this update, which went live about 18 hours after Ars published this initial post. Researchers have discovered an extremely critical defect in the cryptographic software library an estimated two-thirds of Web servers use to identify themselves to end users and prevent the eavesdropping of passwords, banking credentials, and other sensitive data. The warning about the bug in OpenSSL coincided with the release of version 1.0.1g of the open-source program, which is the default cryptographic library used in the Apache and nginx Web server applications, as well as a wide variety of operating systems and e-mail and instant-messaging clients.
Sandbox (computer security) In computer security, a sandbox is a security mechanism for separating running programs. It is often used to execute untested code, or untrusted programs from unverified third-parties, suppliers, untrusted users and untrusted websites.[1] The sandbox typically provides a tightly controlled set of resources for guest programs to run in, such as scratch space on disk and memory. Network access, the ability to inspect the host system or read from input devices are usually disallowed or heavily restricted. svn cleanup failed–previous operation has not finished; run cleanup if it was interrupted August 1, 2013 Anuj Varma svn cleanup failed–previous operation has not finished; run cleanup if it was interrupted All content on this site is original and owned by anujvarma.com.

Defense in depth (computing) Defense in depth is an information assurance (IA) concept in which multiple layers of security controls (defense) are placed throughout an information technology (IT) system. Its intent is to provide redundancy in the event a security control fails or a vulnerability is exploited that can cover aspects of personnel, procedural, technical and physical for the duration of the system's life cycle. The idea behind the defense in depth approach is to defend a system against any particular attack using several independent methods. It is a layering tactic, conceived by the National Security Agency (NSA) as a comprehensive approach to information and electronic security.[1][2] Defense in depth is originally a military strategy that seeks to delay, rather than prevent, the advance of an attacker by yielding space in order to buy time. Using more than one of the following layers constitutes defense in depth.
