Security Applications

One of David's pet peeves is security, or rather the lack of it.
File System Saint:

Don't get me wrong, I like Tripwire. It was the first, but it's certainly not the easiest thing to set up. What I dislike about difficult things is not just that I'm lazy (I am), but difficult often means someone, somewhere will misconfigure or otherwise nullify all the good the program should do. This program is fast and easy. Not necessarily better, but different. Requires: Perl and Perl module Digest::MD5.

datedif:

This small C program will calculate the number of days between any two dates. Granted, this has somewhat limited use, but the author does present an example. It is most useful in scripts. How many days until Christmas? Requires: glibc.

motion:

I like this little application. It was designed so that you could connect a (surveillance) camera to your system, run motion, and it would take pictures each time the image changed. You can make a movie, even send an e-mail. Yep, great for security. But I (ab)use it differently. I connect my video camera after taking a home movie, let motion grab frames every second. Then I load all the images into xv and delete what I don't want and rename what I do want. Much faster and easier than doing it manually—a lot of options. This is a keeper. Requires: libjpeg, libmysqlclient, libz, libcrypt, libnsl, libm, glibc.

Until next month.

Linux Management with Red Hat Satellite: Measuring Business Impact and ROI

Linux has become a key foundation for supporting today's rapidly growing IT environments. Linux is being used to deploy business applications and databases, trading on its reputation as a low-cost operating environment. For many IT organizations, Linux is a mainstay for deploying Web servers and has evolved from handling basic file, print, and utility workloads to running mission-critical applications and databases, physically, virtually, and in the cloud. As Linux grows in importance in terms of value to the business, managing Linux environments to high standards of service quality — availability, security, and performance — becomes an essential requirement for business success.

White Paper
Private PaaS for the Agile Enterprise

If you already use virtualized infrastructure, you are well on your way to leveraging the power of the cloud. Virtualization offers the promise of limitless resources, but how do you manage that scalability when your DevOps team doesn’t scale? In today’s hypercompetitive markets, fast results can make a difference between leading the pack vs. obsolescence. Organizations need more benefits from cloud computing than just raw resources. They need agility, flexibility, convenience, ROI, and control.

Stackato private Platform-as-a-Service technology from ActiveState extends your private cloud infrastructure by creating a private PaaS to provide on-demand availability, flexibility, control, and ultimately, faster time-to-market for your enterprise.
