Apache HTTP Server is a free software/open source web server for Unix-like systems, Microsoft Windows, Novell NetWare and other platforms. Apache is notable for playing a key role in the initial growth of the World Wide Web,and continues to be the most popular web server in use, serving as the de facto reference platform against which other web serversare designed and judged.

Apache features configurable error messages, DBMS-based authentication databases, and content negotiation. It is also supported by several graphical user interfaces (GUIs) which permit easier, more intuitive configuration of the server.

sysrqd is a tiny daemon aiming to control sysrq over network.SysRq stands for System Request, and this are functions mapped to keyboard shortcuts by the kernel. You can use them by pressing Alt+SysRq+[key] (SysRq might be named “Print Screen” on your keyboard),Permits to execute usual SysRq commands by network, like: sync, umount, reboot, poweroff, sak, term, etc. where key can be s (sync), k (sak), 0 to 9 (logging level), b (reboot), etc.

The goal of this keyboard sequences is too be available even if you can’t do anything on your box, because you screwed up everything, or because it’s crashed or under very heavy load.

sysrqd can help you to use SysRq keys when you are not in front of your box,and you need to do Emergency Sync, R/O remount and reBoot.

In this howto we will learn how to build a Dynamic DNS Server. Normally when we configure DNS, we use static entries to resolve any FQDN. If we are using DHCP in our network which gives dynamic IPs to every computer that turns on or requests one, then it is not possible to configure DNS statically. For that we should configure our DNS with DHCP in a manner that whenever a computer gets a new IP, its FQDN will be automatically updated with the new IP in DNS.

Want to give your IT security or administrator staff access to Windows applications right in their preferred Linux desktop environment? Follow this tip and you can easily do this without needing to set up an expensive and complex Citrix environment. Also, did I mention that the following solution can be set up using free software?

Many network and security administrators want to use Linux as their operating system of choice due to the abundance of open source security tools available for Linux. But they still may need to run some Windows-only applications. So, their choices are to run a separate physical system or run Windows XP as a VM on VMware Virtual Server for Linux.

To install RPM files with Yast, simply type the following at the command line :

yast -i file.rpm

Afterwards you can easily remove these packages from within Yast.
If you downloaded source code from a program (tar.gz files) you can quickly make an RPM file from it to install it later on your or another pc (if dependencies are OK).

To do this...

  • Friday's security updates
  • Researchers poke hole in custom crypto built for Amazon Web Services
    Underscoring just how hard it is to design secure cryptographic software, academic researchers recently uncovered a potentially serious weakness in an early version of the code library protecting Amazon Web Services. Ironically, s2n, as Amazon's transport layer security implementation is called, was intended to be a simpler, more secure way to encrypt and authenticate Web sessions. Where the OpenSSL library requires more than 70,000 lines of code to execute the highly complex TLS standard, s2n—short for signal to noise—has just 6,000 lines. Amazon hailed the brevity as a key security feature when unveiling s2n in June. What's more, Amazon said the new code had already passed three external security evaluations and penetration tests.
  • Social engineering: hacker tricks that make recipients click
    Social engineering is one of the most powerful tools in the hacker's arsenal and it generally plays a part in most of the major security breaches we hear about today. However, there is a common misconception around the role social engineering plays in attacks.

  • Cyber Monday: it's the most wonderful time of year for cyber-attackers
    Malicious attacks on shoppers increased 40% on Cyber Monday in 2013 and 2014, according to, an anti-malware and spyware company, compared to the average number of attacks on days during the month prior. Other cybersecurity software providers have identified the December holiday shopping season as the most dangerous time of year to make online purchases. “The attackers know that there are more people online, so there will be more attacks,” said Christopher Budd, Trend Micro’s global threat communications manager. “Cyber Monday is not a one-day thing, it’s the beginning of a sustained focus on attacks that go after people in the holiday shopping season.”

Slackware Live Edition – Beta 2

  • Slackware Live Edition – Beta 2
    Thanks for all the valuable feedback on the first public beta of my Slackware Live Edition. It allowed me to fix quite a few bugs in the Live scripts (thanks again!), add new functionality (requested by you or from my own TODO) and I took the opportunity to fix the packages in my Plasma 5 repository so that its Live Edition should actually work now.
  • Updated multilib packages for -current
  • (Hopefully) final recompilations for KDE 5_15.11
    There was still some work to do about my Plasma 5 package repository. The recent updates in slackware-current broke several packages that were still linking to older (and no longer present) libraries which were part of the icu4c and udev packages.
