Using the GNU Privacy Guard

Post date: April 16, 2005, 00:04 Category: Software Views: 2427 Comments
Tutorial quote: Tonight we will investigate the gnupg utility (version 1.07). I will be running it on an OpenBSD 3.2 system but, as usual, any unix-like system should not display any significant differences. I will assume that GPG is already installed.

The GNU Privacy Guard can be regarded as a complete replacement for the popular PGP (Pretty Good Privacy) software. The difference between the two is that GnuPG does not have any licensing restrictions and it also runs on more platforms. They are both open source products. Although owned by a commercial entity, a freeware version of PGP is available (although only for Windows and Macintosh).

In a nutshell, what all this software does is allow two parties to communicate securely. This implies the following:
- the message has arrived at its destination unaltered
- the message can only be read by its intended recipient
- the authenticity of the sender has been verified by the recipient

Gnu Queue: Linux Clustering Made Easy

Post date: December 22, 2005, 19:12 Category: System Views: 2960 Comments
Tutorial quote: GNU Queue makes it easy to cluster Linux workstations. If you already know how to control jobs running on your local machine, you already know how to control remote jobs using GNU Queue. You don't even need special privileges to install and run GNU Queue on your cluster--anyone can do it. Once you've discovered how incredibly easy it is to cluster Linux environments with GNU Queue, you'll wonder why organizations continue to spend so much money on comparatively hard-to-cluster Windows NT environments.
