A Practical Guide to Fedora and Red Hat Enterprise Linux (5th Ed) Wow. Mark Sobell hits another one out of the park. Comprehensive can hardly describe this book, although I am hard pressed to come up with a more appropriate word. This massive volume covers all things Fedora and Redhat, from the common to the […]
The other day I was talking about how to install Rocks Cluster. Well, today I’ll give you indication on how to test it out a bit. Now this is surely not the *proper* way to test the cluster out, which would be to run some fancy cluster-aware graphics rendering application or something of the sort, […]
One of the parts of my day job is dealing with and managing our HPC cluster. This is an 8 node Rocks cluster that was installed maybe a week after I started. Now I was a bit green still at that point and failed to get a better grasp on some things at the time, […]
Even though I wrote and use OSM I also use Nagios at work (along with OSM). Actually, I administer Nagios there, however I have never actually installed and configured it. It was in place before I started there. That being said, my manager asked me how to get it installed and running today, as he […]
On an rpm based system, say CentOS, first make sure that the rpm-build package is installed. In your user account, not as root (bad form and all) make the following directories: mkdir -p ~/rpm mkdir -p ~/rpm/BUILD mkdir -p ~/rpm/RPMS mkdir -p ~/rpm/SOURCES mkdir -p ~/rpm/SPECS mkdir -p ~/rpm/SRPMS mkdir -p ~/rpm/tmp And create an […]
OK, I must be doing something wrong here, so if you are familiar with building rpms and can help me out, please do! I am trying to build an rpm which has (for the sake of discussion) a script file in it that I want to install. The first thing I did was to install […]
Just a quick update. If you do channel bonding on your ethernet, there apparently is really no good way to tell the speed of your interface. I tried mii-tool to see what the interface looked like, but I was horrified to see it reported 10bt half duplex on 2 bonded 100bt full duplex connections. After […]
There is a first tome for everything right? Well, today was my first time setting up ethernet channel bonding on RedHat; RHEL 5.3 x64 to be exact, but any RHEL 5 or CentOS 5 should be exactly the same. I found a great tutorial at http://www.linuxtopia.org/online_books/rhel5/rhel5_administration/rhel5_s1-networkscripts-interfaces.html. I’ll repost the relevant bits here lest they become […]
Let me preface this by saying that if you are not running Ossec on at least your external facing machines, then you should be. It’s great software! The reason this post is here is for reference mostly and maybe to be able to help someone out later via their favorite search engine. I have been […]
I am sure some of you have been wondering why I recently dropped off the face of the earth. Well, my company sent me to RedHat training last week. Now most of you know I have been “doing” Linux for a very long time. Some of you may recall that I used RedHt early on, […]
