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.

Debian Clusters – This site is a series of step-by-step tutorials for anyone interested in building a Debian cluster. It is geared particularly towards those interested in a Debian cluster for education or research purposes. This site is being written alongside the construction of a real Debian cluster at my institute, starting from the ground (basic networking, DHCP, DNS, authentication) up through installation a queue/scheduler and scientific software.
However, these tutorials and guides take some assumptions about users for granted, including basic Linux and Debian knowledge (see the Basic Linux Skills page for clarification and pointers to resources). This is not meant as an introduction to Debian or on how to cluster in general – thankfully, there are plenty of helpful tutorials and guides already in existence on those topics. A basic understanding of Debian and cluster technology will aid in following the tutorials.

SSH: What and How | Nettuts+ – Many web developers use SSH (“Secure Shell”) on a daily basis to manage their servers, back up files, work remotely, and a myriad of other tasks. Today, I’ll explain what SSH is, do a brief history review, and, lastly, teach you how to set it up on your remote server or even your local network. Let’s get started!
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.

Server-Side: Mobile-OTP Authentication Server (MOTP-AS) Full blown RADIUS server specifically for Mobile-OTP. include: - authenticating users by RADIUS (and optionally PAM or Apache) - SQL database for user/device configuration - Administration Web Interface
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.
