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same time avoiding the problems of pre-packaged installations coming with your Linux distribution, which are most times outdated and provide no regular updates.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!
