Oracle Redhat 5.9 Administration

Hello!
I'm pretty new to the world of Linux. Right now I use Ubuntu Desktop 14.04 Later down the road I plan to install LAMP to try to run a web server.
Generally speaking, I prefer GUI (as most people, I guess), though I have no problem with CLI (remember myself in 1990 with MS-DOS).
As a regular user I don't think I really need a firewall in Ubuntu. Sticking to installation defaults is fine by me. But as an admin of a web server, I would think that I'm gonna need something beyond the Desktop ed. defaults security-wise. I'm aware of IPtables, of course. But to me it seems a little bit too much to learn, too steep of a learning curve right now. Then there's ufw.
And a GUI front-end of it, which is Gufw. Here opinions vary. Some say, I must learn IPtables, others think that Gufw does its job fine.
So what I'm asking here is not just an OPINION, but also a reasoning behind it. Real life example maybe etc.
Thank you.

I am totally unaware about linux;but I am suggested by my teachers to learn REDhat. i am not getting how to start;from where to get REDhat operating system;which book or online site to refer to;so that i can start learning REDHAT.
please as my question;give me a detailed answer.I really am naive at Linux.

I had my pc built & the person that built it suggested linux, but I don't know what version I have seeing as I'm a novice at computers.

Hi guys

We are urgently moving Oracle application to a backup server for some patching etc. The backup server is installed with Oracle 6.6 64Bit linux with default partitions. We found that the system has ext4 file system, while our external storage through HBA interface/IBM is formatted with ext3 file system.
Hence, please let us know what kind of performances issues we may come across, or the same could be ignored?

regards

Hi. Sorry to be so stupid, but I just managed to load and install this Linux (which I really like a lot) on my previously windows <--(bad) system.
But now I need to upgrade some software (like Adobe flash), and I have no clue how to do this. I understand I should go to my original linux distrubutor, and select software thru them (my "Linux distro").
But actually, it's been awhile since I did the install, and I dont exactly remember where I even got this distribution. (I know, I'm dumb--sorry).
Is there a way I can look at my linux system files and see who my distribution is thru, and where is their website. Or would it be easier if I just went thru the whole download and install of linux again <--(not really looking forward to that).
Or even, am I wrong about going thru the distro to do installs/upgrades?
Anything you can tell me will be greatly appreciated.

I am a basic computer user as far as operating systems are concerned. I do a little programming here and there but nothing special yet.

I have tried Linux many times, but I'm always left to getting *another* distro, after I fail to properly install Linux. Basically I resort to simple installs and found that Linux Mint and Ubuntu, most of the time work out of the box. However, after an installation, ... here and there I get error messages and sometimes crashes and i understand that my installation is not stable, simply because I did not properly configure some conf file or similar.

Another even more important problem I have is device drivers. Working from the command prompt (console) and the GUI is very confusing to me. I'm not sure if I'm setting something right with one and then unsetting it with the other. So basically I'm here with some noob questions and a couple specific ones.

1. Can someone recommend a good distro to learn to correctly configure drivers with manually. Remember, that I understand that there are distros that work out of the box mostly, but I actually am not worried about complexity as far as someone can guide me through errors. Which will lead to more questions of course.

2. After an installation there are sometimes a dozen errors during bootup, but no stops. Since it all scrolls by fast (most distros), where can I check after bootup what I need to fix?

The Goal is an *error free* stable installation of a linux distro, with enough common sense learned to take it to other distros.

Hello all.
I have been using Linux OS's of and on since 1996. I completely gave up on MS in 2006. I change out a hard drive in my PC and MS thought I should purchase a new site license, I did not agree with that train of thought.
I found that popping in a disk and getting Linux up and running was easy to the belief that "Nothing could be this easy". It really was. The learning curve was encountered when trying to make Linux Fly. I recommend that everyone new to Linux or anyone with a desire to do a bit more than e-mail, catalog some photos or music get your hands on a Linux command reference guide and learn the terminal. There is so much to understand and do With Free Open Source Software and there are so many ways to access, install and configure the available software. There are so many resources for help and trouble shooting all things Linux however, here's the caveat; I really had to learn how to ask the question to get an answer that worked for me. General question will get you general answers and rarely ever was the answer I sought found the hodgepodge of generalities found in forums or Google searches and the like. I learn to be very specific in my question and the answers were discerned with less difficulty. There are really answers or fixes for the questions I have had concerning Linux.

Hello,

My job is having me get back into Linux. It has been awhile since I messed with it. My company releases Software that runs on Linux. As such, when we release a new version of the software, we have it packaged with the entire Linux OS. As such, when it is sent to our clients, they install, and then have to reconfigure, the Host Name, IP Address, Netmask, and Gateway. Our test environment consists of over ten different Linux boxes and configurations. To make life easier for me, I have written a shell script allowing me a menu to change all of these and to also enable or disable the gateway and how to set/change the localadm password.

I want the script available to users to be able to run it anytime they need to. It works great. I would like to add one more thing to this. I want to be able to run the script automatically on the very first boot after the installation. The script is set up where you have to log in as root to run it. So here is the process I want to happen:

Install Disk
System starts up for very first time after install
Automatically logs in as root and runs script
Exits as root.

I realize Linux will only do what I tell it to. How do I tell it to do this?

Hello

As a learning experience, I want to jump from Windows 7 to Linux full time on my laptop. This isn't because of some antiWindows bullshit or because its free or anything like that. I just want to learn the ins and outs of Linux like I pretty much know on Windows.

I plan to go with Ubuntu. LTS or latest stable version? Thoughts?

First off, compatibility. I do need that all my hardware on my laptop be compatible. From shortcut keys to wifi. This is not a brand new laptop so there shouldn't be any problems. Its a Dell Vostro 1510.

Next, software. Basically on this laptop software I use in and out: uTorrent, Teamviewer, WMP, mIRC, Skype, vSphere Client, Microsoft Office......That's pretty much it IMO. Also Facebook and YouTube (Flash) are a must. I will run all this software in WINE. I don't want (most) of the Linux ports. Im not looking to replace programs I like and use daily. Just looking to replace the operating system.

Next, virtualization. Due to some things (like Office) cannot be ran in Linux, I use a VM. VMWare with its unity feature pretty much gives me what I want.

Next, streaming. I need to be able to stream media from a WS2012R2 to this Linux installation. Special setup?

Anything that is blowing over me, please mention.

Thank you
