TalkingTree  The Long Road to Red Hat Certified Engineer

 

Linux Pocket GuideIn 1999 I purchased my first PC from a local trade show where small vendors built the PC according to a printed spec sheet where the consumer would check off components that would comprise the final product. It reminded me a lot of ordering sushi.

My friend Ken Sugino, a computational neuroscientist student at Brandeis University, encouraged me to install Linux on it. I had never heard very much of Linux back then, but since Ken and I ordered identical PCs, both lacking an operating system, he recommended we install Red Hat Linux 5. Thus began my fondness for the fine grained control over an operating system and its applications that I never before witnessed on any Windows 98 or Mac OS 7, 8, or 9 system.

I recall that the state of Linux was still pretty raw back then and out of the box support for new hardware was often lacking. For example, when Ken finished examining the motherboard spec sheet and tuned all the jumper switches to provide a custom hardware setup, we moved on to searching the web for a solution to overcome a problem where X would not start -- X is the windowing or graphical interface for Linux -- and soon we found an esoteric hack for the video card chipset settings that did the trick. Much of my early experience with Linux was like that. It was the Wild West of operating systems.

Linux - Free... as in waterSeveral years have passed and during that time I've performed hundreds of Linux installations on tens of machines. My Linux skills were initially derived from hours and hours of tinkering like this, but the major jumps in my knowledge level came from taking Red Hat Linux courses from Red Hat itself. I've completed the basic system administration and networking classes often separated by several years between them. Starting with RH253 Networking and Security for Red Hat 7, then 2 years later going back to RH133 System Administration for Red Hat 9, and in 2005 the RH300 Rapid Track to RHCE course for RHEL4, which is whirlwind survey of the material covered in the earlier classes.

The RHCE is was rated at the Hottest Certification for 2006, although it has been in the top 10 for many years now. I recently overheard an RHCE instructor stating that the test is designed to cull the herd of Linux SysAdmin wannabes such that the RHCE test averages about a 30% success rate, and that if the test scores creep up towards the 40% success rate that Red Hat then redesigns the test to push the bar higher again. Last fall I had my first experience with the RHCE exam, and I walked out of the exam shattered, knowing that I had not passed well before receiving my scores. Last month, I paid out of pocket for the RHCE class again, and although I did much better that time, still I did not pass the six hour exam.

StudentWhile the material was still fresh in my mind, I spent a month working on my weakest Linux skills to ramp up for another repeat of the exam in May. In fact the week before this exam I set up a small Linux network at home so that I could practice the System Administration and Networking skills over and over. FTP, DNS, Mail Servers, Pop Servers, Web Servers, Proxy Servers, iptables firewall rules, RAID and LVM, automounting, NIS, LDAP, NFS, Samba, and more... these are the core components of the exam which overlay basic prerequisites such as shell scripting, controlling services, system initialization, and booting. To say that the course material and the exam are comprehensive is an understatement.

Feeling very prepared and wanting to take the exam again as soon as possible, I booked a flight and an exam at my own expense, since this had become such a strong personal goal. Last Friday I caught a 6:30 AM flight from Boston to Baltimore. With the help of a hell-bent taxi driver I made it from BWI airport to the test facility in Columbia, MD at exactly 9:00 AM, the start of the test. Red Hat As described on the RH300 Exam detail page, the first half of the test is troubleshooting a live system, and the second half is the installation and configuration of a production quality Enterprise Linux box. This test is not a short multiple choice exam. You're in it for the long haul of almost six tortuous hours.

Similar to my last exam, I was the first one finished this half, and with a faster time, too. During lunch, while waiting for the instructor to configure the classroom for the second half of the exam, the examinees waited together in the break room, making nervous chatter and keeping a close eye on the clock, wishing the second half would start already. There's no point in trying to study much more at this point. If you didn't know it by then, you weren't going to learn it during lunch. For the second half of the exam I was the only one to finish early, and all the other examinees used the full time alloted. I went back and carefully checked the requirements several times before feeling satisfied that I correctly completed as much as I could.

Back at the airport, I waited five hours before my 10:00 PM flight, but the time went well because I felt very secure in my test performance this time. Finally at home around midnight, I logged on to check my email to see what happened during the day, and to my surprise at the top of my inbox was a message titled "Certification Lab Exam results" with a paperclipped attachment. With a last burst of adrenaline, I raced through the message text to see the words "RHCE Certification: PASS". And there it was, a glowing score of 100% on the first half and 94% on the second. As tired as I was from such a long day, I could hardly sleep after reading this fantastic news.

For me this is a true academic achievement built on years of learning, and I'm very proud to claim the rank of Red Hat Certified Engineer.

Congratulations Steve. YOu have done well and can be very proud of yourself.


I don't usually comment on random blogs but reading that made me smile and somewhat happy for you. Congratulations Steven!


Congratulations!! I briefly looked at the requirements for taking the RHCE exam a few years back when I was first getting into Linux. In short, it's probably the most intimidating and comprehensive set of requirements I've ever seen for a technical certification. I think that the majority of certifications are arbitrary and a waste of time and money. The RHCE is the polar opposite of this stance. Hopefully this achievement earns you some additional compensation from Adobe! ;)


Thank you for your support!

I hope to produce some ColdFusion articles to share what I've learned in Red Hat training, such as how to use iptables and configure a set of firewall rules appropriate for ColdFusion in "normal" and distributed mode, or how to ideally configure User, Group, and SELinux permissions for a document root such that the ColdFusion user and the web developers have minimally sufficient access to this common location.

Also, thanks very much to Terry from Verizon who gave me a ride back to the airport after the exam. This was his first attempt and I could see the pressure weighing on him.


Steven, that would be phenomenal. As I mentioned in one of my recent entries ("ColdFusion Needs A Roadmap"), we are going to be buying new production CF servers and will be running RHEL 4 on it. I want to take advantage of the SELinux features, but I'm worried it might be too complicated for our installation. I look forward to any and all articles/blog entries/TechNotes you may be able to provide. I'm already studying your previous entry on getting SELinux working with CF. It's a great start!


Congrats Steve! It really sounds like a hard test.


Congratulations Steve!


Congrats! That's definitely an accomplishment to be proud of.

BWT, I tried to post earlier, but your captcha was showing a broken image link.


Well done Steve!!!


Thanks Ray, Peter, Rob, and Andy! I appreciate all the positive feedback on this. (Rob, I think the missing captcha may have been due to some logic that aborted if the referer did not contain 'talkingtree.com', but some browsers don't send a referer so I added another rule to allow "" as the referer).

This is the year where I'm trying to shore up and demonstrate the skills I've learned while support ColdFusion customers over the last 6 years. So far this year I've earned a Computer Security Cert from Stanford, a Java Developer Cert from Boston University, and now the RHCE. Within the next few weeks I hope to finish the Adv ColdFusion 7 Cert, and by the end of the summer a Photoshop cert. In the Fall, I'll complete the J2EE cert from Boston University as well. Technical Support was my entrance into the industry, but who knows what the future holds...


I realize I'm behind the power curve on this one, but congratulations. As a Linux enthusiast - hardly a Linux expert - I've frequenly though about taking the exam and making Linux a bigger part of my professional life, but after reading your account...I'm not sure I'm quite that, ahem, enthusiastic. :-)

I had no idea the certification was that intense. I tend to agree with Dave's assertion that most certifications are a waste of time, money and energy. Those that I've taken in the past - including the ColdFusion exams - have left me with no particular measure of satisfaction of having achieved certification, but this one sounds like the certification really means something.
