Well, it looks like it has every single package in both archs. The big concern is that it has Firefox in both i386 and x64 and that just feels bad.

Can someone point me to a guide or something that explains software raid, both creating the array and managing the array?

What is the oldest actively supported version of Linux? RHEL is v5, 2007, Ubuntu is v10.04, 2010. Looking at other Unix variants like OpenBSD, FreeBSD only have about 18 months of support. Not to start a flame war, but it's sort of commendable that Microsoft would support XP for 11 years. Looks like RHEL 5 will have support until 2020? Good Lord.

RHEL is supported for a minimum of twelve years. Customers can buy extended support if they desire.

I'm starting to get the hang of Linux, I think. I haven't caused a major virtual catastrophe yet, anyway. I've been wondering something, though. What exactly does "sudo" mean, and what does it do? Why do certain commands work with sudo, but not on their own?

What exactly does "sudo" mean, and what does it do? Why do certain commands work with sudo, but not on their own? There's a million things that people think "sudo" represents ("su do" where su means any number of things), but sudo will execute the command that follows it as another user (the superuser by default), and programs that require privilege escalation will usually tell you that and quit without actually doing anything. Think of installing a program on Windows or deleting someone else's user directory. And, as always, you can type "man sudo" into a terminal prompt to get probably everything you want to know about how to use it. Hadlock posted:What is the oldest actively supported version of Linux?

What exactly does "sudo" mean, and what does it do? Why do certain commands work with sudo, but not on their own? Have you ever had to use "run as" in windows and gotten a UAC prompt? That's pretty analogous to sudo; it's a way to run a command as a different user, typically root AKA the SuperUser. You can pretend sudo is an acronym for Switch User DO or Super User DO if that makes more sense for you. It would be pretty terrible if just any user to delete the "Program Files" directory so you need to elevate permissions to do that in modern windows and in the same way you would need to elevate permissions to delete /bin in unixs. The is the same with programs, it would be really terrible if just any user could run a partition editor and blow away your C: drive in windows and the same applies in unix land.

Thanks for the answers to my last question; the article especially was very informative about su and sudo. Can anyone recommend an Ubuntu torrent client that I can apt-get? Somehow, the terminal and apt-get seem much easier than the software center, even though the latter has a GUI.

Like Longinus00 just mentioned Transmission is already installed on your computer, and it's good.

I am going to murder Java. I am trying to get the loving plugin to work in Chrome and I just cannot get it to go. I need it in order to connect to my work VPN. No matter what or how I install Java (including following instructions like this) Chrome denies that it's installed. I'm about to lose my drat mind. edit: I'm starting it with --enable-plugins just in case that's still a thing, I've tried creating the symlink in /opt/google/chrome/plugins which is apparently how it works in Ubuntu too. I'm using the 32 bit version as is required according to Oracle. Nothing. Works. Adult Sword Owner fucked around with this message at 16:01 on Mar 13, 2013 |

It wasn't requiring root to use a printer was it? I thought it was requiring root to install or configure a printer. It means that a user can't install a new printer in their own profile and I think even some basic settings like paper trays or size may need root. The issue was his daughter needed to install a network printer for her school on her laptop and couldn't.

Correct, system-config-printer or whatever needs root. Once configured it can be used by non-privileged users.

Yeah sorry, I'm on my phone. For some reason my diction correlates to the ease with which I can input text. I'm used to a university situation where people frequently borrow many different private printers, so requiring root just to set up a printer means the user is authenticating a lot.

Does Red Hat handle all external output devices the same? Do you need root to mount a USB thumb drive, or to enable display/desktop spanning to a second/external monitor? HDMI is a two way high speed data bus that supports TCP/IP.

I posted this on the XBMC forum but got no responses, perhaps you guys can help? I'm running my own setup of XBMC on Ubuntu, I have it configured so openbox is launched at startup which runs XBMC via autostart.sh. When it starts up it's full screen and everything is great. The problem I'm running in to is when XBMC (not the computer) goes to sleep and turns off the display, when it wakes up the window decoration appears on XBMC. This is incredibly irritating as the only real fix is to reboot it  I have the following as my rc.xml which should disable decoration and prevent the above issue from occurring. code:

Hey, my first desktop Linux question in ages! I have two nVidia cards installed in my work computer. One is a Geforce GT 610 x16, and the other is the same card in an x1 flavor. Is it possible, using either the Nouveau or proprietary driver, to have a 3-screen configuration? Pure Xrandr is preferable, but I'll use Xinerama if I have to. I'm not loving around with multiple screens, that poo poo sucks.

Lets assume that I am rusty as hell on coding, but can basically follow along on simple stuff (because it is true). Lets also assume that I need to as quickly as absolutely possible make Linux second nature (also because it is true). I'll be using Fedora 16 mostly. Besides putting Linux on a VM or a throwaway partition and just start messing around in it what are the best ways to very quickly crash course my way through learning Linux backend? Any guides or pdfs or even books that can supplement hands on learning with free being the optimal price but I can shell out some cash if it is particularly worth it. A friend has a goal of going from novice to compiling an OS on his own in six months and I am determined to beat him with as wide a margin as possible, making as much progress as I can, in particular, in the next two months so I can qualify for a promotion. Do you guys have any suggestions to help me out? I'm starting to burn through linux.org, but what else?

I think the best way is to make things that are relevant to your life or something you'd like to do. Create an emulator, host some media, have a mail server, host a webpage, install cacti(graphing for system statistics) things like that. I always find that it's far harder to learn something by force when you don't have any sort of personal investment. Just going through some webpages about how to do things will only teach you that, how to do it. Not why it's done or why it's done for x y and z reasons.

Well I guess specifically it will be stuff related to Linux server environments. Aforementioned friend got a level 1 VPS for us to mess around in. So any guides on cool or essential things to do by bash commands to maintain a server would be cool. Learning about root access WHM right now and have pretty much mastered cPanel at this point minus any ancillary stuff like cronjobs scripting or MySQL work.

Or would I need to do db first? Or should I just wait until I ssh in to start worrying about this? Also not really directly Linux related but any of you guys have a good resource to reference to master eximtail/grep/log to troubleshoot smtp issues? I'm Googling around right now but if you happen to have something bookmarked I'd appreciate it.

Or would I need to do db first? Or should I just wait until I ssh in to start worrying about this? Just wait until you have SSH access. Most of these require databases to be created beforehand, though. You should install a VM (that's not a deprecated version of Fedora -- don't use that on a server that's public facing, it's not going to get security fixes) and go through the CentOS Deployment Guide and/or the FreeBSD handbook, both of which will tell you everything you really need to know about basic server administration, including DNS, SMTP issues, and the like. Obviously, you have to know something about SMTP before you can troubleshoot it (tried by hand with "telnet someserver 25"?). A RHCE study guide wouldn't be a terrible idea either, since it covers most of those concepts. Twilight is exactly right, though. You need to know when and why to do things, not just how. Don't bother installing poo poo from source (maybe ./configure && make && make install on one or two very small projects). All that teaches you about is cryptic gcc/autoconf errors that you have to Google if it breaks, and almost nobody installs from source in the "real world" (I'm excepting ports, portage, homebrew and the like, because they handle dependencies and are basically full-fledged package managers). Use a package manager. Once you're comfortable with that, learn how to build RPMs from source tarballs (again, the RHCE study guide will tell you how to do this). If there's a package for it, you should prefer that. You're going to fail. You're not going to become a Linux expert in six months. You should read a RHCE guide anyway, because it's your best bet.

Install a SVN server and get it working through httpd. Harden the server and use a suite to probe it or find a friend who knows how to do it and ask them. Get an rsync backup system in place and then cause a failure and restore it. My own unrelated issue I am dealing with: This user can't get into one of our main servers via ssh. I've had her do -v and this is the output after she enters her password quote:debug1: Authentication succeeded (password). After this, nothing happens, it just freezes. There were hilarious things happening before like the presence of an RSA key on her machine that was being sent to the server, which didn't expect an RSA key and was halting at the key authentication stage (before it moved onto password), so I'm expecting some other awful nonsense to be at work.
