Red Hat Training Review

The following is my perspective of the Red Hat classes I have taken.  I am very happy with training I have received from Red Hat.  If your goal is to become certified, I highly recommend taking advantage of the courses.  Currently (July 2012) I have successfully completed the RHCSA, RHCE and RHCVA exams.

The most important step is to take advantage of the self-assessment online

RH300 - RHCE Rapid Track Course with RHCSA and RHCE Exams
RH300 - Course Description
RH300 is a fast-paced review over 4 days to prep for the exam.
I felt as though quite a few people who attended this class at the same time as myself did not understand the goal of this particular class.  RH300 is not for the squeamish.  You should NOT hope to learn a lot from this class.   If you are a proficient Linux (read: Red Hat) Administrator and simply need some guidance on what to expect and what to study for, this class is for you.  The RHCE is no joke.  I highly recommend the following book: Michael Jang - RHCSA-RHCE study guide (make sure you get the version which covers RHEL 6).  Review the exam objectives from Red Hat's website.  The test is quite fair, but it may cover topics that you may not use frequently (i.e. SElinux and IPtables, iSCSI)

RH318 - Red Hat Enterprise Virtualization (RHCVA)
RH318 - Course Description
I was quite pleased with the RH318 course.  I had only a few months experience with Red Hat Enterprise Virtualization as I signed up for the Eval of RHEV 3 when it was released (Dec 2011/Jan 2012).  There is quite a bit of material for them to cover and I feel they chose a very relevant design for the class to focus on.

P2V using dd for KVM-QEMU guest

Preface: I have certainly not exhaustively tested this process.  I had a specific need and found a specific solution that worked. Situation:  I was issued a shiny new laptop running Red Hat Enterprise Linux 7 (with Corp VPN, certs, Authentication configuration, etc...)  The image was great, but I needed more flexibility on my bare metal.  So, my goal was to P2V the corporate image so I could just run it as a VM. * Remove corporate drive and install new SSD * install corp drive in external USB-3 case * Install RHEL 7 on new SSD * dd old drive to a disk-image file in a temp location which will be an image which is the same size as your actual drive (unless you have enough space in your destination to contain a temp and converted image) * convert the raw disk-image to a qcow file while pushing it to the final location - this step should reduce the disk size - however, I believe it will only reduce/collapse zero-byte blocks (not just free space - i.e. if you de...

Extending SNMP to run arbitrary shell script

Why are we here... This is not likely something I would have pursued under normal circumstances.  I happen to be working for a customer/client who is not afforded a lot of flexibility to accomplish their goals.  In this case, the rigor is justified.  They have to sometimes be fairly creative with how they solve problems. In this case they would like to utilize an existing snmp implementation to execute a command (or shell script) on a remote system.  They came to me with the idea of using Net-SNMP extend. https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/sect-System_Monitoring_Tools-Net-SNMP-Extending.html NOTE:  This is NOT a good implementation strategy in the "real world"  it will simply allow you to test the functionality.  There are a TON of security implications which would need to be taken in to consideration. Implementation Steps: [root@rh7tst01 ~]# yum -y install net-snmp net-snmp-utils ...

RHN Satellite Server (spacewalk) repomd.xml not found

"repomd.xml not found" If you add a channel, or if your RHN cache gets corrupted, and one of your guests complains that it cannot find repomd.xml for jb-ews-2-x86_64-server-5-rpm (for example) - you need to rebuild your repodata cache. Normally this is an automated job - which is exemplified by the fact that you have obviously built out your entire Satellite environment and never had to do any of the steps you are about to do. So - some prep work: Open 3 terminals to your Satellite Server and run: # Term 1 cd /var/cache/rhn watch "ls -l | wc -l" # Term 2 pwd cd /var/log/rhn tail -f rhn_taskomatic_daemon.log # Term 3 satellite-sync --channel=jb-ews-2-x86_64-server-5-rpm Once the satellite-sync has completed, you >should< see the count increment by one.  If you are unlucky (like me) you will not. You then need to login to the Satellite WebUI as the satellite admin user. Click on the Admin tab (at the top) Task Schedules (on the left) fin...
