Debian

An apt-get primer

Post date: April 12, 2005, 17:04 Category: System Views: 3471 Comments
Tutorial quote: If any single program defines the Debian Linux project, that program is apt-get. apt-get is Debian's main tool for installing and removing software. Working with the .deb package format, apt-get offers sophisticated package management that few Red Hat Package Manager RPM-based distributions can match.

Besides the convenience, an advantage of apt-get is that it reduces the chances of falling into dependency hell, that limbo where software installation fails for lack of another piece of software, whose installation fails for lack of another piece of software, and so on. If you know how Debian's archive system works, and how to choose the sources that apt-get uses, and use a few precautions in your upgrades, then the chances are that dependency problems will never bedevil you. Should you descend into dependency hell anyway, apt-get offers useful tools for climbing out of it.

Enhancing kernel security with grsecurity

Post date: November 25, 2005, 21:11 Category: Security Views: 3731 Comments
Tutorial quote: Is your server as secure as it could be? Sure, you use a firewall, mandate strong passwords, and patch regularly. You even take a proactive approach by performing security audits with tools such as nmap and Nessus. Yet you may still be vulnerable to zero-day exploits and privilege escalation attacks. If these possibilities keep you awake at night, you're not alone. The sleepless folks with the grsecurity project have developed an easy-to-use set of security enhancements to help put your fears to rest.

Highlight Domain & Subdomain for SSL websites in Firefox

Post date: May 27, 2009, 22:05 Category: Security Views: 4345 Comments
Tutorial quote: When you visit a Secure website in Firefox chances are that the FavIcon for the website is replaced with a Green bar with the details of the company. This is because of the default properties in Firefox to display detailed information of the website from the Extended Validation Certificate on the website. However, if the website doesn’t host a Extended Validation certificate then the website URL (link) in the address bar is not highlighted or in otherwords shows as a normal website URL.

Postfix Virtual Hosting With LDAP Backend & Dovecot (IMAP/POP3) On Ubuntu 8.04

Post date: August 3, 2008, 10:08 Category: Installing Views: 4185 Comments
Tutorial quote: I have been running with a MySQL backend for virtual hosting for some time, but when I discovered Phamm and the added FTP feature I decided to switch to LDAP as backend for Postfix with virtual hosting. In view of the fact that the installation and configuration guide of Phamm is lacking some basic information it took me quite some time to put it all together and get it working. Piecing it all together was not simple so I would like to share how I configured it and got it all working toghether.

Ruby on Rails on Red Hat

Post date: November 27, 2006, 07:11 Category: Network Views: 8323 Comments
Tutorial quote: Ruby on Rails is an open source freely available web development framework. It's been quite popular--it won a Jolt "Web Development Tools" award last year, and some prominent Java developers have publically switched to Ruby on Rails. The buzz surrounding Rails is quite impressive--particularly when you consider that Rails had no Fortune 500 company to market it, unlike .NET or Java.

Rails is a Model View Controller (MVC) framework. As you can imagine from the name, applications written using Model View Controller frameworks have three main components: a model, which represents the data and associated logic; the view, which represents how a user interacts with the application; and the controller, which contains all of the business logic that drives the application. This is an artificial distinction, of course, but it is a powerful one.

You'll need Apache 2.0+ and MySQL installed on your Red Hat Linux computer to run these examples.
