Today at SCaLE10x: System Administration Study Group

January 20, 2012 – 9:26 am

If you haven’t heard my ranting and raving about the SysadminSG last weekend at FUDCon, it went pretty well. Turns out, this weekend is another run of the event. The goal is to help Fedora contributors (and others) prepare for the tough world of Linux system administration.

If you attend the event, you will receive two study guides and an ec2 instance for about 24-hours. The idea is that you will spend the day today studying with others to improve your system administration skills. There are no instructors, but I will be there to get the ec2 instances setup and help with any non-study related issues.

If you are interested in the sysadminSG,  come visit us at SCaLE10x today:

Southern California Linux Expo 10x (SCaLE10x)
Los Angeles Airport Hilton – Catalina C
9am – 5pm

Cheers,

FUDCon Blacksburg: sysadminSG, Fedora Infrastructure, pam_otp and more!

January 19, 2012 – 1:47 pm

Well, FUDCon Blacksburg has come and gone. I believe it was the most productive I’ve been at a FUDCon EVER! I was able to get quite a bit accomplished and much more than I had planned!

What was it that I did, you ask? Well let me tell you all of the tasks I was able to complete.

System Administration Study Group

Over the past year, I’ve been working on a way to do a regular free study group for those who want to improve their system administration skills, get certified, or just brush up on something they didn’t quite understand.

Enter sysadminSG, a self-guided tour of many of the standard tasks any system administrator should know. The main goal was to create an instance of a Fedora 14 machine for studiers to use.

Some of the tasks on the study sheets indicate certain issues that would need to be resolved which can’t be resolved without a ‘master’ instance. I was able to recruit a couple of excellent individuals to help get this further than I thought it would. Jon Stanley and Ivan Makfinsky helped put together many of the pieces which will help studiers get more done. Specifically, an ldap server for centralized authentication and iscsi target luns for use with LUKS encryption, LVM and disk partitioning.

Fedora Infrastructure

I attended the Fedora Infrastructure session, where we covered two major things of concern. One was removing the puppet staging branch and moving everything into ‘Production’. This is a mental shift for many, but makes sense because in truth, everything maintained from an infrastructure perspective is production.

Additionally, a longer term plan of being able to spin up ‘staging’ environments for any new things that will go into production looks to be the direction we’ll be going. Many of the applications we have in Fedora require some work to get us to this point, mostly so they can be more atomic pieces. I think a proof of concept environment will provide us with an good idea of how much work will be involved.

pam_otp

After the Fedora Infrastructure hackfest, there was a two-factor authentication hackfest. We discussed using Yubikeys and a unique PIN together for authentication within Fedora. The initial goal was determined to setup sudo authentication for sysadmin-main group with two-factor authentication.

Nathaniel McCallum found the pam_otp library and was able to get it to compile. He passed it on to me to test and document it, which I was able to get working after a drunk night by the fire. I was then able to document the usage of it and have a test rpm that we’ll be using.

All in all, it was a very productive weekend and more work will be getting done over the next few weeks as well. It’s all very exciting and fun, a really good reason for attending FUDCon!

Cheers,

Herlo

FUDCon Blacksburg 2012: Three days to the Sysadmin Study Group

January 11, 2012 – 9:28 pm

This Saturday, January 14, 2012 at approximately 1pm Eastern Standard Time, I will be running the System Administration Study Group (SysadminSG) at the Fedora Users and Developers Conference being held in Blacksburg, Virginia.

We did a successful version of the SysadminSG at the Southern California Linux Expo (SCaLE 9x) last year.  And thanks to Ben Williams prodding several months ago, I agreed to run this event again. Note: We will also be running the SysadminSG again at SCaLE 10x on January 21, 2012 as the Fedora Activity Day (FAD).

What is the System Administration Study Group (SysadminSG)?

The System Administration Study Group or SysadminSG is intended as a gathering of individuals with a common purpose, studying and preparation for the Red Hat Certifications. The two main certifications of focus are the Red Hat Certified System Administrator (RHCSA) and the Red Hat Ceritfied Engineer (RHCE).

This is a self-guided workshop for those who gather, it does not have any instructors. However, proctors will be around to assist as needed.

The SysadminSG could be used for many other reasons. The Fedora Infrastructure team is always looking for skilled system administrators. The study group is a great way to bone up on the technologies used by Fedora Project administrators every day.

Why should I participate in SysadminSG?

Because it’s cool, and other reasons, too!

Okay, while it is true that participation is the cool thing to do, it is also very possible you may wish to improve your system administration skills. Doing so with others in the room to bounce questions off can be very helpful. Studying by yourself is challenging and while IRC is nice, there really is nothing like real live people in a room, with similar goals.

So I am interested. What do I need to bring/provide to get me started?

To participate in this event, please bring a laptop, PC or some other computer with a current version of Fedora pre-installed. YOU DO NOT WANT TO INSTALL THE DAY OF THE STUDY SESSION!!

Amazon ec2 instances will be used where possible, so that things can be portable. The instances should be up and running for around 24-hours, which means if you don’t finish during the study session, it’s possible to continue for a short time after the workshop. To access an ec2 instance, it will need to be setup with an ssh public key, so come prepared with one.

Note: If the machine you bring has the capability for Virtual Machines using KVM or VMWare, we can work with that as well, but you may receive mixed results.

Resources! Pig for Wheat!

Okay, stop screaming about it! There will be plenty to do during the 4-hour session, but if you want to get a head start, read up on these guides.

Contributions encouraged and accepted

One of the main goals of the study group is to come up with tasks that would be representative of each of the objectives listed. It is my hope that with a bit of contribution during the session, we can discover and improve the study group to make it a regularly occurring workshop. I would like to see these study guides go from big sections of blank to something more tangible. It’s possible each objective could have two or three tasks for a future SysadminSG workshop.

See you all at FUDCon this weekend!

Cheers,

herlo

Presenting at PLUG Tomorrow: GoOSe Linux – Rebuilding Enterprise Linux the Community Way

January 10, 2012 – 3:06 pm

Well, this has been a long time coming. It’s taken over 6 months of hard work by our community. Tomorrow night, January 11, 2012, I will stand in front of the Provo Linux User Group (PLUG) and talk about what we have been working toward.

GoOSe Linux – Rebuilding Enterprise Linux the Community Way

Yes, GoOSe Linux is almost here and we’re ready to discuss the process and the goals of our little community. If you have been hearing me rant about GoOSe on the Utah Open Source Planet, Google Plus or Facebook and want to hear more. Or if you are just plain bored tomorrow night with nothing better to do, come down to the Provo Linux User Group. Learn more about how the Enterprise Linux Rebuild community is working together to make a better ecosystem.

If you can’t make it, or want to preview the slides, you can get them on my speakerdeck.com page. I look forward to seeing you all there.

More Sysadmin Study Group than you can handle! FUDCon Blacksburg and SCaLE 10x

January 4, 2012 – 12:15 am

As mentioned previously, there will be a Sysadmin Study Group workshop at FUDCon.

Now we’re announcing the Sysadmin Study Group will be the Fedora Activity Day at SCaLE 10x!

So Exciting!

Well, it’s been a week since the first run of my ec2 instances for the SysadminSG (or System Administrators Study Group).Things look promising. The folks over in #fedora-cloud and #boxgrinder have been especially helpful! Thanks a ton msavy and gholms and rbergeron too!

The plan here is to grant every user in a room access to an ec2 instance for 24-hours. It may be shorter or longer, depending on a few unknowns at this time. After some additional testing tonight, I think just a bit more work and the workshop will ready. We still need to update the Study Guide to match the RHEL6 RHCSA exam and RHCE exam requirements, so if anyone wants to take that on, just let me know and I’ll point you in the right direction.

If you are looking to do some RHCE prep with others, come on down to the Sysadmin SG workshop at either FUDCon Blacksburg or SCaLE 10x! We look forward to seeing you there!

Cheers,

Herlo
