  • Graphvis visualisation of Nagios Config – Nagios Exchange – Graphvis visualisation of complex Nagios configs.
    I have written a couple of utilities one to walk a nagios config tree and turn it into a perl hash (called nagparse)and another to use that hash converting the tree into a graphvis directed graph (called graphit). These are then brought together with a CGI program called explorenagios that lets you select what parts of the config to graph. If you have a non trivial config then showing it ALL in one graph is not fun!

    You can use the two component programs on the command line too – and feed the output into dot (it has been optomised to make nice dot graphs) or one of the other engines like neato if you want to do some hacking of the output options.

    It is now useful enough to be worth sharing. Not prefect yet but useful. Surprisingly fast.

  • Nagrestconf README – What is Nagrestconf?
    Nagrestconf is a REST interface and configuration GUI for Nagios.
    Nagrestconf is written in Bash and PHP.
    Specifically, Nagrestconf:
    allows Nagios configuration files to be written using a REST api.
    allows the server to be restarted using the REST api.
    provides a configuration Web GUI built on the REST api.
    It can be useful for:
    Bulk loading
    Bulk editing
    Automation
    Catching common configuration mistakes
    Configuration Delegation (using additional tools)
    Distributed monitoring (using additional tools)
    Not all of the Nagios directives are implemented, refer to the Status section.
  • Oracle Linux: A better alternative to CentOS – We firmly believe that Oracle Linux is the best Linux distribution on the market today. It's reliable, it's affordable, it's 100% compatible with your existing applications, and it gives you access to some of the most cutting-edge innovations in Linux like Ksplice and dtrace.

    But if you're here, you're a CentOS user. Which means that you don't pay for a distribution at all, for at least some of your systems. So even if we made the best paid distribution in the world (and we think we do), we can't actually get it to you… or can we?

    We're putting Oracle Linux in your hands by doing two things:

    We've made the Oracle Linux software available free of charge
    We've created a simple script to switch your CentOS systems to Oracle Linux
    We think you'll like what you find, and we'd love for you to give it a try.

  • configure time service on AIX host – Waldemar Mark Duszyk – First, you have to decide/select the appropriate devices to be your time providers. It could be one or more “official/public” time servers or maybe your routers. When you decide what these servers are you should validate that they deliver what you need and that you are (your host) is capable to receive and use what is delivered.

  • Tony’s VMware Site – I have assembled a package which you can download which will allow you to have Sound, Network, and CD ROM in your Windows For Workgroups 3.11 Virtual Machine.  I also have found a copy of Netscape 4.0 which will work with Windows 3.11.
  • Michele’s blog » Temperature in your server room – At work we bought a couple of Ethernet Boxes from MessPC to keep an eye on our different server room and monitore temperature, humidity and the presence of smoke. These Ethernet boxes are quite neat: they have one network port (10 Mbps half/duplex only, beware) and four RJ-45 ports where you plug-in the sensors you need. We got sensors for temperature, humidity and a smoke alarm.
  • Nagios plugin debugging – This little perl-scripts captures STDOUT and STDERR of a nagios plugin. It writes the captured output to a temp. file. Then the output is returned to Nagios for further processing.

    This allows to track down some problems when using plugins within Nagios. You'll get some information if you have problems accessing files, can view the expanded command-line parameters of service checks, view the performance data returned in a text file, etc.

    It did help me several times – so feel free to try this out.

  • Mobile-OTP: Strong Two-Factor Authentication with Mobile Phones – Mobile One Time Passwords (Mobile-OTP)
    strong, two-factor authentication with mobile phones

    Using static passwords for authentication, as it is commonly done, has quite a few security drawbacks: passwords can be guessed, forgotten, written down and stolen, eavesdropped or deliberately being told to other people.
    A better, more secure way of authentication is the so called "two-factor" or "strong authentication" based on one time passwords. Instead of authenticating with a simple password, each user carries a device ("token") to generate passwords that are valid only one time.

  • Open Monitoring Distribution – Wiki – OMD – Welcome to OMD – the Open Monitoring Distribution. OMD implements a completely new concept of how to install, maintain and update a monitoring system built on Nagios.

    OMD avoids the tedious work of manually compiling and integrating Nagios addons while at the same time avoiding the problems of pre-packaged installations coming with your Linux distribution, which are most times outdated and provide no regular updates.

    OMD bundles Nagios together with many important addons and can easily be installed on every major Linux distribution. We provide prebuilt packages for all enterprise Linux distributions and also for some other, such as Ubuntu 11.04.

  • Linux Malware Detect | R-fx Networks – Linux Malware Detect (LMD) is a malware scanner for Linux released under the GNU GPLv2 license, that is designed around the threats faced in shared hosted environments. It uses threat data from network edge intrusion detection systems to extract malware that is actively being used in attacks and generates signatures for detection. In addition, threat data is also derived from user submissions with the LMD checkout feature and from malware community resources. The signatures that LMD uses are MD5 file hashes and HEX pattern matches, they are also easily exported to any number of detection tools such as ClamAV.

  • Portable Ruby | YELLOSOFT – Now you can run Ruby from a USB drive!

    AllInOneRuby is a wonderful automated way to generate Ruby binaries. We just made one ourselves for those out there that don't have access to a full Ruby installation. We ran allinoneruby.rb to generate the binaries: version 1.8.6-26 for Windows and 1.8.6.111 for Linux.

    To make it easier to run Ruby scripts, we included some run files. Double click them to begin running Ruby programs. Edit them to point to your scripts.

    Mac users, don't feel left out! Mac OS X 10.4 and later come with Ruby built-in! So copy your Ruby scripts along with this Portable Ruby package onto a USB drive. If you designed your programs correctly, they'll now be runnable on Windows and Linux too!

  • BAT file tips | Alex @ Net – Let's play with BAT files a little. As you may know, BAT files are intended to be run and processed by the MS command processor, named cmd.exe, and the programming language they are created with is very close to BASIC. The early versions of the BAT-files language (which comes from famous Windows ancestor, MS-DOS) were very limited. Nowadays it has more features and a few days ago I created a small collection of interesting tricks, related to BAT file programming. You can check the following examples that demonstrate which execution flow controlling statements BAT-file language has and show their analogs in PHP.
  • 10 Tools To Add Some Spice To Your UNIX Shell Scripts – here are some misconceptions that shell scripts are only for a CLI environment. You can easily use various tools to write GUI and/or network (socket) scripts under KDE or Gnome desktops. Shell scripts can make use of some of the GUI widget (menus, warning boxs, progress bars etc). You can always control the final output, cursor position on screen, various output effects, and so on. With the following tools you can build powerful, interactive, user friendly UNIX / Linux bash shell scripts.

    You can start immediately. It is especially suitable for comparing these different monitoring solutions. Note that OpenNMS is written in Java and produces a high load on the system. Starting and Stopping OpenNMS takes a long time (several minutes!).

  • Squid Block – DNSBL Redirector for the Squid Proxy – dnsbl_redir is a shamelessly derived redirector based on the asqredir redirector written by Thomas Zippo < thomas at zippo dot ch >. Thanks!
    Its been rewritten to use a DNSBL list (RHS type) to check for and block sites listed in the DNSBL. It will redirect your users to the page/site listed in the top of the dnsbl_redir.h file.

    dnsbl_redir is written in C. It consists of one small source file and a small(er) .h file. It has been tested and runs on the current Squid versions. It performs very well on Linux (RedHat/Fedora), BSD and technically should compile and run on any gnu/linux.
