Nagios XI wizards make setup a snap for network monitoring

One of my last TechMails to ever be published by TechRepublic is Nagios XI wizards make setup a snap for network monitoring. This tip looks at using Nagios XI, a really slick commercially-backed install of Nagios with a really incredible GUI frontend for configuring Nagios. Anyone who has configured Nagios by hand using vim and a stack of text files will appreciate the web interface to configure it from top to bottom.

Chromium on Fedora Linux is closing in on Firefox

The TechMail from a few weeks ago was Chromium on Fedora Linux is closing in on Firefox which takes a look at using Spot's Chromium for Fedora repo (thanks Spot!) to get Chromium running on Fedora. I have to admit that in the last month or so, I have thoroughly enjoyed running Chromium on Fedora 14 (F15 will be upgraded to this weekend hopefully), and don't miss Firefox at all (although I still ...

Practical SELinux: Port contexts and handling access alerts

Last week was my third and final part of my series that introduced SELinux on Techrepublic: Practical SELinux: Port contexts and handling access alerts. This one finishes off what we were looking at in part two, and introduces port contexts (ensuring that a program can only listen to specified ports and nothing else), and shows us how to use sealert to look at violations that SELinux is reporting and how we can fix ...

Two SSH clients to consider for the iPad

This week's mac tip is Two SSH clients to consider for the iPad. In this tip I look at two really great SSH clients for the iPad (and iPhone as well, although I was mostly just looking at the iPad versions which do vary from their iPhone counterpart): iSSH and Prompt. Really great clients for anyone that needs to SSH into a remote box. They're quite inexpensive and very well done.

Work some project management magic with Merlin

Last week's mac techmail was Work some project management magic with Merlin where we look at using ProjectWizards' Merlin project management software. If you need project management on steroids, Merlin is a good bet. Even more importantly, if you need an easy way to share project management files within a group or with co-workers, Merlin is probably the only real contender on the mac right now.

Practical SELinux for the beginner: Contexts and labels

This week's techmail is Practical SELinux for the beginner: Contexts and labels which is part two of my series on SELinux.

If you're new to SELinux, this is a good primer to get you started.

Introduction to SELinux: Don't let complexity scare you off

This week's techmail is Introduction to SELinux: Don't let complexity scare you off. This is the first of a three-part series that introduces SELinux and digs into some of the basics on how to change policies, add policies, troubleshoot SELinux, and basically give you enough info to not feel intimidated by it, and enough rope to hang yourself with it (just kidding!). So if you were like me and kept turning SELinux ...

Enhance security on your Mac with Hands Off!

This week's mac techmail was Enhance security on your Mac with Hands Off! which is a neat security tool for OS X. I've been using Little Snitch for years, and Hands Off! is quite similar except that it provides more features and functionality, including the ability to protect files and directories on the hard drive with applicable policies to programs. Want to default deny access to files, and allow only trusted applications ...
