Tell me about Linux/Unix Certifications

[filkenjitsu]

Ok, I work in Telecommunications and have been told that learning Unix would be beneficial to my career. I have played around with it in the past and have even taken a college course or two on it years back, but it has been way too long.

So, Solaris would by my optimal platform, but i would like to just generally learn unix/linux as it could not hurt.

So, could someone break down the different certifications for me? Please list the easiest to the hardest. I am just talking about learning the operating system, commands, possibly scripting. I am not concerned with programming.

Does anyone have input on this entry level exam through Sun?

Thanks guys! I know this is the best place to ask this question!

I'm curious what people think about Sun... Do many places use it? I don't think its as distributed as it once was, but I could be wrong.

I was considering getting a SCSA, but I read passing score was 50% for the tests.... I kinda wonder what having the cert really does for you with such a low pass score.

Solaris still has a pretty big presence, and it's only grown ever since Sun open sourced it. It's overall future is somewhat in flux with the acquisition by Oracle, but for the here and now, it's worth learning. It's also worth learning Linux and either NetBSD or FreeBSD. FreeBSD has always had a pretty big presence in the Unix world, and Linux's presence has been steadily growing ever since IBM got behind it.

For the most part, Unix is Unix, and you can functionally move between versions without much difficulty. Each implementation has it's quirks, and if you have to work with that platform, you'll have to do some research, but it's not like you'll need to learn everything from scratch. Usually the biggest issues between versions is in how they boot and how they update. Userland utilities are pretty standard across the board (take that with a grain of salt though, as there are differences... particularly in Solaris land.. some of it's commands do entirely different things than other Unix versions, and many of it's commandline switches/options are different, but even with that, it's not really that difficult to work with)

Everyone ends up with their favorite flavor of Unix one way or another. I, for example, am a big fan of Debian Linux, and it's primary derivative, Ubuntu

[hypnotoad]

I wish there was some kind of certification for Ubuntu-style (debian) linux -- there are about a million distributions based on debian. apt is, and always has been, far superior to rpm

Not that I want to start a huge war on that topic...

Yes it's very beneficial for you to get into UNIX if you work in telcos, because almost all the backend applications run on UNIX, and you need to know your way around.

You will find Solaris and Linux a lot, and it's a skill sought after.


I didn't take the Associate Solaris certification, as it's new. I have SCSA and SCNA.


I recommend you take the official training offered by SUN, and I really can't recommend it enough. The books they give you are exactly what you will need in your job...

Find the trainings here:
System Administration Training (SCSA) | Sun Solaris Certification

You can order the material and try self-study if you have the necessary background though..

I recommend you prepare a practice machine..and preferably a SPARC machine (so you can play with OBP, very helpful for troubleshooting) if you have one at work..otherwise use a PC and install Solaris x86. Then practice each and every topic in the SCSA...I believe it has everything a Mid-level Admin need.





As for Linux...I don't have any certs yet, but I will soon. Most respected one is RHCE because it's lab-based. You can start with CompTIA Linux+.

LPI 1, 2, and 3 are really good certs, and the information in the books are priceless.

If you learn Solaris or Linux or any flavor of UNIX and got the chance to do enough hands-on work, then any UNIX flavor will be easy for you to learn. Getting the opportunity to get hands-on experience is not easy..

My recommendation is, you pick a certification, and start with it. Practice each and everything in the books. Practice means try all the options, break the machine and fix it.
You need this kind of experience, troubleshooting/administration experience.


Very often I meet UNIX Admins who get stuck in things that are part of the SCSA cert. I can't stress the topics there enough.


Good luck

...I'm curious what people think about Sun... Do many places use it? ...

Ideally you see Sun products in Telcos and financial services field.

A lot of Telco vendors like Motorola, Ericsson, and Nokia deploy their applications on Solaris. They also use HP-UX and AIX...but Solaris is heavily used. It's a huge market.

Sun storage is also coming in the picture now, after the successful mid range products (6140, 6540, 6580..etc).


You see Solaris with Oracle DB, and you should be seeing more of this in the future as Oracle acquired Sun now.

Solaris works well for heavy back-end DB applications.


I see more Linux in web applications, and web hosting. I also see more Linux than Solaris in Mail servers, ldap, and DNS servers.

....
I was considering getting a SCSA, but I read passing score was 50% for the tests.... I kinda wonder what having the cert really does for you with such a low pass score.

The problem is not with the low passing score, the problem is with those cheat and pass without knowing rat arse about Solaris or IT.

The exam isn't easy, and it really tests your practical knowledge...but you get a lot of paper certified people..that's the real problem here ! I wish it was Lab-based like RHCE...

What kind of SPARC machine would you recommend, that can be found on ebay for a decent price?

We don't do huge wars here...only small wars :P

[UnixGuy]

I really recommend any SPARC machines that takes more than 4 Hard drives, so you can practice Solaris Volume Manager (and Veritas Volume manager later, it's not part of the test). It's one of the most important topics.


I learned on "Sun Enterprise 450". It has everything you need. Make sure you request it with 4 hard drives of the same size.


Sun Enterprise 3500...all these obsolete machines are really heavy duty and can take more than 4 Hard drives.


you can also buy "Sun Blade 1000" or "Sun Blade 2000" with SCSI HBA, and buy SCSI Multi-pack storage so you can have more than 4 hard drives.

Wow, that's huge! Sun Microsystems Ultra Enterprise Model 450 Server - eBay (item 370272664787 end time Nov-08-09 12:32:47 PST)

The wife will love seeing that in the home office, lol. Thanks for the info.

I know !! and it got wheels LOL

it looks like a small fridge

We had one of those at the last place I worked. Guess who had to move it when it was replaced?

Mu ugliest encounter with this machine was at one ISP. The SCSI controller failed and I had to replace it. I almost dissembled the whole machine and inhaled a mountain of dust !

After the torture of replacing the controller (which took 30 minutes !) it didn't start up LOL...I had to go all over again and re-seat everything, then it worked !

[hypnotoad]

Sun also offers hardware evaluation units if you qualify -- they'll ship you out a multi-thousand-dollar brand new server to use for 60 days

hehehee...I removed Volume Manager on one of those back in the year 2000.
