> Did you write down the commands for every topic Red Hat states in their website for RHCSA?
>

I did not - however, I've been a "Linux/UNIX admin for 15 years" so the commands are either quite familiar or easy enough to look up specifics from the test system during the exam. Now, the RHCE - I studied my @$$ off for. I know some people in this subreddit essentially don't care about the NDA, or skirt the line - I try not to do either, if I can help it. So, I can't answer your questions thoroughly, but I can still provide some advice.

> Also, are all those topics exactly what is going to be on the exam or that is a tough/general outline? Thank you very much...

The outline is pretty accurate as to what you can expect on the exam.

There are a few very important "tips" regarding the exams:

  • know how to help yourself in a semi-disconnected environment. Know where to find the example configs, how to install the different documentation packages on how to use them (man, info, etc...)
  • be sure you reboot and watch the console during the boot sequence (if you're really diligent reconfirm that the previous solutions are still applied - i.e. if you know that you updated the firewall previously, make sure those changes survived a reboot)

    Other tips:

  • Get Michael Jang's guide - I thought someone had mentioned it had been released. Amazon is still showing a preorder. I have not used his guide for RHEL 7 - but his RHEL 6 guide got me through the RHCE (with a 100% actually).
  • take a Red Hat class.. and yes, I know they are expensive. I thought you could access the RHEL 6 classes online now for free though (I'll try and find a link and update this thread).

    Some times you have to get creative. Like pulling down an RPM to look at the pre/post scripts and rpmbuild files to get some guidance on how to do something.

Yes one can, in the USA.

Gratuitous licenses are revocable. Always have been, and currently are as-well.
If you want to secure terms you must pay for them.


David McGowan Esq. made a correct statement of the law:

>David McGowan, Professor of Law, University of Minnesota Law School:

>"Termination of rights

>[...] The most plausible assumption is that a developer who releases code under the GPL may terminate GPL rights, probably at will.

>[...] My point is not that termination is a great risk, it is that it is not recognized as a risk even though it is probably relevant to commercial end-users, accustomed to having contractual rights they can enforce themselves.

>p46 "As long as the project continues to honor the terms of the licenses under which it recieved contributions, the licenses continue in effect. There is one important caveat: Even a perpetual license can be revoked. See the discussion of bare licenses and contracts in Chapter 4"
--Lawrence Rosen

>p56 "A third problem with bare licenses is that they may be revocable by the licensor. Specifically, /a license not coupled with an interest may be revoked./ The term /interest/ in this context usually means the payment of some royalty or license fee, but there are other more complicated ways to satisfy the interest requirement. For example, a licensee can demonstrate that he or she has paid some consideration-a contract law term not found in copyright or patent law-in order to avoid revocation. Or a licensee may claim that he or she relied on the software licensed under an open source license and now is dependent upon that software, but this contract law concept, called promissory estoppel, is both difficult to prove and unreliable in court tests. (The concepts of /consideration/ and /promissory estoppel/ are explained more fully in the next section.) Unless the courts allow us to apply these contract law principles to a license, we are faced with a bare license that is revocable.
--Lawrence Rosen

>p278 "Notice that in a copyright dispute over a bare license, the plaintiff will almost certainly be the copyright owner. If a licensee were foolish enough to sue to enforce the terms and conditions of the license, the licensor can simply revoke the bare license, thus ending the dispute. Remeber that a bare license in the absence of an interest is revocable."

--Lawrence Rosen

Some notes:
A license without an attached interest is revocable in the US (other countries have different laws, which is why many OSS repos kept out of the US in the past, it is also why the FSF is both a 501(c)(3) charity and also requires copyright assignment to them for any contribution they accept (otherwise an author who was still the copyright owner of the code could rescind the license to the code)).

Opensource friends like to bring up the recent district court decision in california to try to argue the the GPL is a contract. (It's also interesting that they started adding CoC's right after said decision, to push out the men who created OpenSource) They are wrong. Acquiescing to a preexisting duty is insufficient for consideration. They like to quote this part:

>"Not so. The GNU GPL, which is attached to the complaint,provides that the
Ghostscript user agrees to its terms if the user does not obtain a commercial
license" (Artifex v. Hancom, Case No.16-cv-06982-JSC, page 4 line 17)


This is false on its face.

The GNU GPL contains no such language.

The /business agreement writing/ that Artifex wrote up and posted on its webpage includes such language. The court here is conflating "The GNU GPL" with the writing Artifex published on it's webpage. It is an error on the courts case. A typo by whomever who drafted the decision perhaps (conflating Artifex's contract language with the GPL itself).

The court goes on to allow Artifex to recover on either breach-of-contract grounds (for the amount a commercial license is worth) OR to go forward with a statutory copyright infringement action. If the GPL alone was a contract, there would simply be two different state-law breach of contract theories to pursue (breach of the "business offer" writing or breach of the GPL "contract", and the court would dispose of the case that way).

u/mikeeusa · 0 pointsr/redhat

>GPL can allow lawsuits for violation of its terms. Making it revocable at that point, but I have never seen this avenue.

For paid-for licenses, that is true: the only way to revoke is via the terms, should they exist (if they do not exist, that's a different story). This is why companies prefer paid copyright-license-contracts over free bare-licenses. A bare license can be revoked at the issuers will.

It's basic property law, you learn it in property 101, contracts 101.
Furthermore following a pre-existing duty is not valid consideration for a contract.
Thus "obeying the license" is not consideration in this instance: nothing allows you to use/modify/etc the property other than the allowance by the issuer via the license.

The GPL doesn't allow anything; it's the law that allows. The GPL's "give us the source (of derivative works)" provisions aren't even enforceable under US law since it alone is not a contract and specific performance is thus not available.

As you can imagine everyone's extremely circumspect about how to study for the test due to the NDAs: advice about what to study can be viewed as tantamount to saying "X, Y, Z is on the test."

Since you have RH 7.2 coming in your shop (congrats!) the best advice comes RedHat themselves: RHCE exam candidates should consult the RHCSA exam objectives and be capable of RHCSA-level tasks, as some of these skills may be required in order to meet RHCE exam objectives.

Having said that Jang's guides get pretty good reviews (Amazon.com). They're comprehensive although as always with a book this size there are inevitably errata. I've never used them but my several of my employees have and liked (CertDepot). Since you have this much time between now and the exam I'd dig deep into the (exam objectives) and make sure you can do those in your sleep.

Exam objectives aside all the shiny new stuff in 7.2 like systemd, networking and selinux are where you'll probably find the biggest gaps in your knowledge as 7.2 rolls out in your site. As a fellow old-schooler I just work under the assumption I'm going to get paged out of bed at 3 AM, I'll be shivering in the datacenter standing at the console of a downed production system and my cellphone can't get a signal, so all I have is what I remember and if I'm lucky the man pages.


Or if that seems unrealistic pretend you're going for a job interview at RedHat and that you must be able to describe commands and procedures to accomplish your job without referring to any external sites like Google or stack overflow.

I highly recommend using Sander Van Vugt's RHCSA/RHCE 7 book. I passed both exams from start of reading page 1 to passing 2mo on each. His book is comprehensive and covers the whole gambit of both exams. But, it doesn't hurt to seek more sources of information.

https://www.amazon.com/RHCSA-RHCE-Cert-Guide-Certification/dp/0789754053/ref=sr_1_1?keywords=sander+van+vugt+rhcsa&tag=hotogobr-20&qid=1561254657&s=gateway&sr=8-1

Set yourself up on VirtualBox ( https://www.virtualbox.org/ ). Create a bridged network to make networking easy. Make sure you sign up for a RH developer account and get the free 1 yr subscription (can renew each year) for a copy of RHEL. While CentOS is binary-compatible, I've run into some oddities with configurations and such while studying for the exams. Practice practice practice. Break things (it's only a lab VM!).

You're probably going to want to setup multiple VMs (at least 2) to toy around with things like SSH, pubkeys, SCP, Samba, NFS, and other network services. If you plan to go on to RHCE, you'll definitely want to setup a FreeIPA VM for LDAP and Kerberos-related stuff. Even the RHCSA touches on connecting a client to an LDAP authentication service.

Thanks for the links and ideas too, I'm hoping to get my RHCSA in the next few months also. Here's what I've been doing:

  • My employer thankfully paid for a course, RHCSA Rapid Track Course (RH199). It was fast paced and very by the book, but I learned a lot. I don't work in a Linux heavy shop, so I'm coming at it from more of a long-term hobbyist perspective. I wanted something that would keep my attention and give me more hands-on with the latest version in a little more directed way.

    http://www.globalknowledge.com/training/course.asp?pageid=9&courseid=15678&country=United+States

  • Linux Bible - http://www.amazon.com/Linux-Bible-Christopher-Negus/dp/111821854X

    Very RHEL/CentOS focused, lots of emphasis on RHCSA/RHCSE. It's more focused on RHEL 6, but if I'm remembering right there is some discussion of sysvinit vs systemd and how to deal with both. Good read overall I think for the future too.

  • The link perfecthashbrowns gave you already has been helpful when the others weren't as detailed as I was looking for.

    I suck at taking tests, but I've been experimenting at home and creating some screwed up scenarios, and I'm getting decent enough to work out of messes. I feel like I'm learning something at least.
u/Codad85 · 2 pointsr/redhat

As /u/Lisenet said, practice with a home lab environment is incredibly important. I personally found linuxacademy.com to be great for learning purposes. For my RHCSA, I used a combination of linuxacademy, small homelab, and 1 book (https://www.amazon.com/RHCSA-RHCE-Cert-Guide-Certification/dp/0789754053).

​

I am now using those same resources to prepare for my RHCE exam.

​

Once you get a basic handle on everything, repetition of the exercises is the biggest help. Best of luck!

“Gun jumping” is a term used by legal practitioners and the Antitrust Division of the U.S. Department of Justice and the Federal Trade Commission (the “Agencies”) to describe the sharing of competitively-sensitive information between parties and the premature combining of parties which are impermissible under U.S. antitrust laws.

Be careful with both your questions and your answers, please. If unsure, err on the side of caution. Once / if the deal goes through, your Red Hat colleagues-to-be will share all of this with you without hesitation, I'm sure. Re our culture - read The Open Organization by Jim Whitehurst, someone else already said it. ;)

u/ArchivisX · 6 pointsr/redhat

I finished my RHCSA with a perfect score using only one resource. While getting access to official Red Hat resources could be better, if you have to fund this yourself, this is the best option for the money. Michael Jang helped me pass my RHCSA on RHEL6 and then again on RHEL7, with the current exam getting a perfect score. All you need to do is follow what is in the book and you'll have no problems passing. Just do the labs thoroughly enough until you no longer need to reference any help material and you'll be fine.

u/swikeRH · 8 pointsr/redhat

Jim Whitehurst, the current CEO of Red Hat, wrote a book titled, "The Open Organization." If reading is your thing, it might give you the best insight as to what it is like to work at Red Hat. There are plenty of non-technical roles that need to be filled at every company, even technical companies like Red Hat. Human Resources is an example of a role that doesn't require the person to understand the "free open-source community." You will, however, be part of an open organization that works much differently than your standard top-down organization.

The video tutorial is great! I signed up for the lab environment and contact hours. I'll be starting that in a day or two after registration is completed.

u/project_valient · 2 pointsr/redhat

"Free" material outside of raw experience may be hard to come by. You can prepare for practically any test scenario on a RHEL server by downloading and utilizing Centos as an operating system, which would be free. To the same tune you can sign up and download as a RH developer and get a free copy of RHEL Workstation.

The objectives for the exam can be found on the RH site for the exam: https://www.redhat.com/en/services/training/ex200-red-hat-certified-system-administrator-rhcsa-exam#Objectives

Other training options include purchasing a book, people really like Michael Jang's guide, or enrolling in the RH124, 134, 200 classes to prepare for the exam.

Sander Van Vugt has a great book that covers rhcsa and RHCE. I used them both to get my RHCE. Not really for beginners. You'll have to do a lot of researching to figure things out not covered in the book. Also plural sight is great video site with some Linux trainings. Linux academy is a great resource too but I think it's a bit pricey after the trial ends.

Stop using Ubuntu, its not wildly different to RedHat but there are quite a few differencess (you may get confused if you're using both) use Centos instead. I suggest you buy a RHCSA & RHCE book.

I took both RHCSA and RHCE without taking the official Red Hat training courses, if that's what you mean. It would probably be very difficult to pass either of them without using any training resources, though. Jang's book should be sufficient, I think, if you're comfortable studying on your own.

Start by reading Mike Gancars' Linux and the Unix Philosophy. Yes, seriously.

Unix (and thus Linux) is as much a way of looking at the problem, a philosophy, as an OS. This little gem (it's only 250-odd pages) will give you a disproportionate advantage entering the new world...

Which certification? I'll assume RHCSA for now, but really the suggestions I'm making are for both.

Check out the RHCSA exam objectives (a similar list exists for the RHCE.)

I don't advise just checking these off if you think you know them. Work through exercises and actually do them.

The Jang book and its companion with practice exams seem to be the go-to books. Do the practice exams.

u/oakenbucket · 0 pointsr/redhat

There is an official, confidential Red Hat course book that is provided in official training. It looks like they are teaching you out of some off-the-shelf book (from 5 years ago!):

>Required Text(s) and Other Learning Materials:
>
> Red Hat Certified Technician & Engineer

> Asghar Ghori

> Endeavor Technologies Inc / August 2009

> ISBN 978-1615844302

...not that there's anything wrong with that. But just so you know, it's most likely not an official Red Hat course.

edit: I looked up that book and it says its based on RHEL5! Old!
