My company's Linux deployment started with one project and 12 servers; a year later we're up to 45 servers, and soon will have more than 300 desktop users when we convert an existing set of Windows workstations to Linux. To manage this growing Linux environment, I rely on many open source applications..."

Since Java is largely distribution neutral, what Java code works on Fedora Core works for Debian, Red Hat, SuSE, Mandrake, and any number of other distributions. And, yes, Java applications really do exist, and some are actually good..."

The move is intended to make the software, which is used to run Java programs, more appealing to corporate developers and customers, who typically favor standards-based software..."

I'm often faced with a situation in which I meet someone who says, "We use open source." Then, she or he names a product I've never heard of. Usually, once I find out what it does, I recognize how useful it is and begin to think of how enterprises can apply it. It just seems like the creativity of the open source community never ends..."

If so, then that type of security is good provided you keep your system secure and some user doesn't have a "ps -ef" loop running in an attempt to capture that sensitive info (though some applications mask passwords in "ps" output). There is a program called "shc" that can be used to add an extra layer of security to those shell scripts. SHC will encrypt shell scripts using RC4 and make an executable binary out of the shell script and run it as a normal...

As in most technological areas, intrusion detection has evolved and specialized. The security industry has grown to include a number of disciplines and subspecialties, each with its own cadre of professionals. Why worry about intrusion detection if you have a good firewall? Just remember: no lock is unpickable. Firewalls have holes so that services can run (web, mail, and so on). Where there's a hole,...

I decided to search the Internet to find out if others were experiencing these attacks and, hopefully, find a solution. I did uncover a lot of information on the subject, but discovered only a few script-based solutions. None of these, however, seemed... well... elegant..."

But if you're interested in what's happening under the hood on your Internet connection, I'll be happy to introduce you to an old and respected command-line tool. Come on, pull that many-pixeled GUI quilt off of you and meet me at the CLI for a look at tcpdump..."

Luckily, I had my /home partition on a separate drive, so I didn't lose precious email, stories, research, and pictures. But it did get me thinking about my lack of preparedness. Where was the back-up system I've talked about for years, but never acquired? This is the tale of how I rectified that glaring omission, and built myself a personal back-up system using inexpensive parts and free software..." More... http://hosting.blogdrive.com/comments?id=177
