  • 5 easy tips to accelerate SSL – Unhandled expression – SSL is slow. These cryptographic algorithms eat the CPU, there is too much traffic, it is too hard to deploy correctly. SSL is slow. Isn’t it? HELL NO! SSL looks slow, because you did not even try to optimize it! For that matter, I could say that HTTP is too verbose, XML web services are verbose too, and all this traffic makes the website slow. But, SSL can be optimized, as well as everything!

  • Security Tips for Apache Web Server – Debian-based Systems – Apache is one of the most widely spread Open Source web server for web hosting in Internet due to its stability, robustness and rich variety of modules and features. Due to its popularity, Apache comes with pre-build binary packages for almost all major Linux distributions and can also be installed on other Operating Systems such as Unix, Windows, Mac OSX, BSD etc. However, a basic installation of Apache on Linux systems, by default, doesn’t offer a full protection against attackers, so a few security measures must be taken in order to protect your machines, web servers and web documents against such types of malicious attacks. This article will provide you a few tips on how you can secure and protect Apache Web Server installed on Debian-based Linux distributions.

  • Regular Expressions – Regular expressions ("regexes") are supercharged Find/Replace string operations. Regular expressions are used when editing text in a text editor, to: check whether the text contains a certain pattern find those pattern matches, if there are any pull information (i.e. substrings) out of the text make modifications to the text. As well as text editors, almost every high-level programming language includes support for regular expressions. In this context "the text" is just a string variable, but the operations available are the same. Some programming languages (Perl, JavaScript) even provide dedicated syntax for regular expression operations.
  • MySQL active-passive cluster | Your IT goes Linux – We will use the iSCSI Lun defined in our iSCSI cluster as a shared storage and we will run MySQL in active-passive (fail-over) mode using Pacemaker and Corosync cluster engine. The cluster will have to connect to the iSCSI target, mount the iSCSI partition on one node and start a MySQL service which has all its data on this partition.
  • Perl – […] Perl has horrors, but it also has some great redeeming features. In this respect it is like every other programming language ever created. This document is intended to be informative, not evangelical. It is aimed at people who, like me: dislike the official Perl documentation at http://perl.org/ for being intensely technical and giving far too much space to very unusual edge cases learn new programming languages most quickly by "axiom and example" wish Larry Wall would get to the point already know how to program in general terms don't care about Perl beyond what's necessary to get the job done. This document is intended to be as short as possible, but no shorter[…]

  • » Linuxaria – Everything about GNU/Linux and Open source SSH in 2 steps on Linux with Google Authenticator – Many security policies require you to change the port number of the SSH service to ensure greater security in a Linux system. Situation now used throughout the IT world and used mostly by users who have their own private server. Today I want to show you how to add another security layer without having to change the SSH port. To do this we’ll incorporate the famous Google Authenticator to our ssh service, in this way we’ll have a safe, two steps security, by entering our password and the combination given from the GA application. Let’s see how to do this…

  • Manuale Android – Androidpedia – AndroidWorld Wiki – Questo è un manuale all'utilizzo di Android. La versione "spiegata" in questo manuale è quella Vanilla ovvero quella pura di Android presente solo su alcuni terminali. Le case poi personalizzano i terminali con varie interfacce (vedi Sense) e quindi a volte stravolgono in parte l'esperienza di Android. Spesso comunque è possibile ricondursi a questo manuale per capire meglio il funzionamento di Android.
  • Marionnet.org – Home – Marionnet is a virtual network laboratory: it allows users to define, configure and run complex computer networks without any need for physical setup. Only a single, possibly even non-networked GNU/Linux host machine is required to simulate a whole Ethernet network complete with computers, routers, hubs, switchs, cables, and more.<br />
    Support is also provided for integrating the virtual network with the physical host network.<br />
    <br />
    As Marionnet is meant to be used also by inexperienced people, it features a very intuitive graphical user interface. Marionnet is written in the mostly functional language OCaml with just some little bits of C, and depends on User Mode Linux and VDE for the simulation part.<br />

  • Sagan from Softwink, Inc [800-538-9357] – Sagan is a multi-threaded, real time system and event log monitoring system, but with a twist. Sagan uses a "Snort" like rule set for detecting bad things happening on your network and/or computer systems. If Sagan detects a "bad thing" happening, that event can be stored to a Snort database (MySQL/PostgreSQL) and Sagan will attempt to correlate the event with your Snort Intrusion Detection/Intrusion Prevention (IDS/IPS) system.
