Best Training in Linux Administration?

Love to Learn Linux asks: "My company is making the move to Linux. I've been a Windows admin the last 5 years and have been asked to learn Linux. I've got some O'Reilly books but I need some hands on experience. My company will pay for any Linux training I choose. I'd prefer an online course to one of those 4 day classroom courses since I'd like to take my time and really learn it. So far, I've been recommended the Red Hat eLearning course and the O'Reilly Learning Lab. Would you recommend either of these over the other, or are there some better choices?"

Use it at home

[SonicTooth]

Install Linux at home. It's the best training you'll ever get. And then switch over your best friends and finally your grandparents. You'll be a pro in no time.

Install Linux at home. It's the best training you'll ever get.

No, it's not. When you just install a distro at home and start using it you'll learn a lot, sure. But what you'll learn a scattershot and mostly just what you need to do to get a functional system, because that's what your incentive is to do. You won't learn best practices and you won't learn why things are they way they are. Heck you probably won't even learn about some fairly basic tools just because you didn't happen to need them. You really need the formality of a structured learning environment (not a class, specifically, but a structured curriculum at least) to make sure you cover everything you need to know.

I know it seems to be the number one recommended method here on Slashdot, but it really has some serious flaws that everyone seems to conveniently overlook. Following your advice leads to sloppiness and "good enough"-ness. Not exactly skills that will endear you to an employer.

[nomadic]

Actually the best training is at work; home networks just don't typically have the complexity you find in a business environment. Unfortunately most people can't just hang out with a linux admin team for a few months to pick up stuff.

Re:Use it at home

[antirename]

Oddly enough, everyone I know who is good at Linux administration (or programming in general) is self-taught. Yes, you wind up with holes in your knowledge, but they are usually small. Take a class, you think you know it all, and all of a sudden you are in over your head when you see something new. I see it all the time in new hires. (I only bring up programming because config files really seem to confuse MCSE's, since there is nothing to click on and you actually have to type.)

Re:Use it at home

[damiangerous]

Take a class, you think you know it all

Exactly, you hear that a lot here about "paper MCSEs". Yet that's just the converse of the typical proposal here: "You don't need a class, you can learn it all by running Slack on your old 486." Yet somehow one is sage advice and the other is mocked. You can't learn without doing, but you can't learn in a vacuum either. Neglecting either one will lead to sometimes critical (from a business standpoint) holes in your knowledge.

Just like you shouldn't take a class and think you know everything before you have real experience, you shouldn't think you've seen it all already "in the wild" and structured learning is beneath you. It's the same personality flaw. It's just manifesting itself in a different way.

Re:Use it at home

[Confessed Geek]

As an actively employed "Linux Systems Administrator" (my real job title) I must concur with "damiangerous." While I was a windows admin I set up multiple linux boxes out of curiosity, slackware, rh5, and it was interesting and educational, but once I was done I just sort of looked at them and was like "Now What?"

Only after I attended a 3 night a week month long class did it all come together.

Don't disregard the classroom setting. A online course or reading o'reilly books (and even the Linux for Dummy's book) are good but for your first introduction a classroom (with hands on training) is the best place to start. If you have a good instructor you won't just learn "the Facts" but will get a better grasp of the implications and how to use the tools, and get some real practical advice.

Your milage may vary as some people are much better book learners while others do better with lecture, but a good class does a really good job of giving a good foundation to start from so additional online or deadtree training is more approachable and rewarding.

Set up a home system first

[AJWM]

Set up a firewall, web server, mail server etc, play with the hardware, reconfigure the things, set up raid, lvm, etc.

Nothing beats hands on, and nobody I've interviewed for a sysadmin job (and I've done quite a few recently) who didn't have a setup at home was any good.

TrainingCamp for LPIC

[Semireg]

I did a 6-day bootcamp style training session with TrainingCamp. I successfully attained my LPIC-1. Out of the 6 people in my class 2 (including myself) had previous Linux experience and we both passed, the others failed. However, having many coworkers and friends that are teaching themselves linux, this would have given them one of the best starting points around. Highly recommended no matter what your skill level.

Go RedHat

[buchalka]

Personally I'd recommend the RedHat training.

This will be more of benefit to you if you actually are going to use RedHat, but of course the general principles will apply.

If I were you, I'd also get Linux on a home machine and start "fiddling" to get up to speed.

Maybe install Vmware or a similar product so you can try different things.

Personally I took a leap and went from Windows to Gentoo linux and never looked back!

Good luck with it.

You could dual-boot an existing Windows machine or run VMWARE so you c

Online courses...

[chrispyman]

If I were you I'd stay away from an online course. From what I've found, they usually aren't much better than just reading and doing reseach on your own, the only diffrence is that they have exams and it adds to your GPA. Perhaps you should find a real class of some type (perhaps one of those weekend campy type deals) and get some real world hands on experience.

Are You Crazy!?!

[eSims]

Take the offsite training!

These days it is difficult enough to get training (at least in the corp America I work in) let alone offsite. A whole week to do nothing but dig in and learn. Take it... then on your own you can always do self paced work and such... it's a win-win.

Good Luck!

Re:Real life

[Anonymous Coward]

Yes, some people mock Gentoo, but installing it is once of the best linux learning experices I've ever had. Even if you don't end up running it...

Still waiting for it to finish compiling, eh?

Set up a small net in your work lab

[SCHecklerX]

As many others have suggested, you should play on your own. I'd still take the class though. Set up a small network BEFORE going to the class, though. Then you will have intelligent questions to ask, and you will have some goals in your training.

In your work lab get 2-3 computers. Set up a linux box as a DHCP and DNS server, then maybe add apache, samba, etc. These are the things that you'll likely be using linux for in the enterprise, right? You can play with firewalling and IPSec if that is your thing too.

After the initial install, go here to learn the rest:
The Linux Documentation Project

The basic sysadmin guide there will give you the basics, and the specific howto's are great for setting up DHCP, DNS, etc.

Another good guide:
IBM Linux Newbie Guide

Set up that small net, play, learn, then go to your class and learn a lot more.

Have fun!

Re:Real life

[eric_ste]

Yep, parent is right. And you have the Gentoo forums to help you if you are in need. Installing gentoo will certainly teach you lot's of stuff. But if you are to become a Linux sysadmin, your first step, IMHO, should be to drop windows and start using Linux on your work computer and on your home computer. Also, get him to give you a few old PC's to play with. Like 333Mhz which you can get for about 50$. On these PC's, don't use gentoo, compiling everything will be much too long. Use a precompiled distribution and preferably the one your Boss wants you to use in prod.

Set up the networking, play with apache, PHP, postfix, Openldap. Create and delete useracounts, explore /etc/init.d, read the rc script to understand how your server boots.

Instead of going on a class, get him to buy good books. I like wrox and Oreily books but others may be good also.
Learn to use man, the sysadmin's bestfriend.

Learn vi. Vi may be hard at first but it is very useful. the linux version is generaly vim. You may also use gvim but it's better to kick yourself in the ass and learn it if you are to become a Unix sysadmin.

Also, a good source of info is generally included in /usr/share/doc.

Finally, http://www.google.com/linux, I could not live without.

I do not know many sysadmins that understood Linux and wanted to go back to windows.

Have fun!

Building "scale" networks is great

[GoClick]

Depending on how complex your network is you might even be able to get the company to fund a "model city" at work in a spare room.

You can use local sources to buy outdated computers, used switches, hubs, routers and etc to build a "dumbed down" low cost clone of your current network which will allow you to learn using it just like the real network, heck even the same IPs if you're going to put that much effort in. You can practice deploying software, using the systems etc. You might also want to get exact (sans-serial-numbers) clones of key servers if possible so you can test things very carefully.

It's a great way to learn but it'll really help to have a guru to get you going.

Find the local Linux User Group and get involved, make friends and then pester them on IM.

Don't forget about the time investment

[damm0]

Yes, everyone I know who is best at Linux is self-taught. But how much time did that take? Valuable lessons can be learned alone, but you can reduce the time it takes by a factor of 10 or more with structured lessons.

I'm talking years here. You can reduce 10 years of lonerdom to 1 year by using structured learning tools. No class is going to teach you to be a guru in 4 days.

Re:Don't forget about the time investment

[SealBeater]

I disagree. I am all self-taught, and I belive that taking a class only
teaches you how to think the way the teacher thinks. I have seen countless
IT people with formal skills approach a problem the exact same way, go through
everything they can remember, once they have gone down the list, they are
stumped. I would much rather be in charge of the training of my brain, esp,
since you can study what you want, it's always "play" and never "work". My
self-teaching has been of tourrmendous advantage, since I, having not
undergone the grinding down of formal education in computers, have developed
novel and unique ways of looking and solving of provblems.

Re:Don't forget about the time investment

[mindstrm]

Courses augment self teaching.. they don't replace it.

I firmly believe that to be a good sysadmin, programmer, technologist, etc, you have to be able to learn on your own.. that is the primary skill you need... and this is why almost every single skilled person you meet in this field will tell you they really learned it all on their own.

School, however, is a source of knowledge.. and not every course is there to teach you a bunch of narrow-minded BS.

If you really want to bean up on a specific area, for instance, you are getting more into Linux, taking a couple courses your employer is willing to pay for is certainly not a BAD thing to take advantage of... especially if you feel you will learn something out of it. Especially if you are a learning on your own kind of guy.. you will absorb a lot from the course. Make sure the instructor is someone who can actually add knowledge to you.. the entire course could be worth it if a handful of your unanswered questions are answered.

I think most of us just suggest "do it on your own, courses are silly" because we want people to realize that learning on your own is the most important skill.. that courses are just a brief foray into some new knowledge.

Re:Pick the hardest Distro

[tunabomber]

I agree with this approach in general, but I think that Linux From Scratch is really the best "hard" distro to learn from. Unlike Slackware, LFS is set up specifically with learning in mind, with very explanatory step-by-step documentation. Just about every aspect of the installation is done by hand- the instructions even show you how to write your own boot scripts.
It takes a long time to get an LFS distro up and running, but by the time you do, you will know your system inside and out even before you've started experimenting with different configurations.

Re:Pick the hardest Distro

[MoThugz]

That's not the best way... that's overkill. Hard doesn't necessarily mean best.

But hey, don't think that I'm knocking off LFS. I went through it myself... but after a year plus of using Slackware (following a year of using Mandrake consistently).

LFS is really useful if you want to understand how to build a Linux distro. It's technically not even a distro. It's more of a commando-style survival training, whereas a distro would be summer camp.

I also doubt the "you will know your system inside and out" argument. I believe "you will know how to build a working Linux system" is a better description of the LFS learning process.

Bear in mind that the poster is a Windows admin for five years... and he wants to have working knowledge of adminning Linux... not building a distro. Moving from Windows, and getting an introduction to Linux via LFS is really not something you'd want to go through.

My recommendation? I live and breathe Slackware... but the poster should really try out a few distros. Fedora Core & Mandrake would scratch that need-some-GUIs-to-get-me-going itch for a start. After that, you might want to try some of the more traditional distros... Slackware and Debian would be my recommendation then.

In the end, Linux is about choice. Just sometimes, the choice isn't yours... just your company's. Take a course on whatever distro they've decided upon... but play with a different distro at home for a different "feel".

Start with a hard distro...

[KermitJunior]

I would recommend you start with Gentoo and move to Debian or Suse.

Before I'm modded flamebait, here's why:
1)Gentoo has some of the best install documents in the Linux community
2)It requires that you set up a lot of things by hand (system logger, kernel if you choose expert, etc)
3)It has some of the best forums/support around. Even Gentoo critics admit this.

After you get gentoo working on your box, wipe it and reinstall. After the fourth or fifth time, you'll actually have learned something. Then wipe and install Debian:
1) Debian has the largest volunteer following.
2) Deb has one of the simplest updgrade paths
3) If you choose stable, its old but very secure.
4)Suse is pretty darned awesome, too.
5)Then make a customized patched kernel for the heck of it.

Just my two cents. I took the Gentoo->Debian Road for the simple reason of learning and it helped.
