(Linux After 3.x Summary) Unics Systems Thesis

I feel very stupid, 20 years ago I was a Unix 5 system admin at a Xerox plant using Sun systems and then Database admin at American Airline for Dec and HP versions of Unix. I have just brought up PCLinuxOS running from the DVD on a laptop and I could not even figure out how to shut down the system without tuning off the power. Any ideas of a good guide?

Hi Guys,

I'm new to this community and i just have a basic Linux knowledge especialy Ubuntu+ UbuntuServer. I'm Studying IT its my last year and im working on a thesis called "Windows Vs Linux". I'm trying to setup a virtual company environment in windows and the same in Linux. I want to compare the both... what are the pros and cons from both operating systems, stability, Security, managability, TCO,... . I did some research and stuff but for the Linux part its not easy... So i have a few questions, hopefully I'm getting some response. First of all I'm thinking of using Ubuntuserver LTS as server side OS and for the workclients Mint or ubuntu. Is this a good distro choice ?

My second and i think its the hardest part of setting up a manageable Linux Company environment is an Active directory alternative that offers the same functionality in Linux. Is this possible ? Ok you have like openlDAP and stuff but thats just basic authentication password and shit, but do you have something like GPOS for Linux ?

I'm hoping someone can help me out a bit

Grtz

In my machine I have dual operating systems (windows7 and sabayon). After installing the linux I found the time was not correct. I had to change the time zone to get it right.

Then when I got back to windows surprisingly I found that the time in windows have also changed. I changed the time in windows and then when I got back to linux the time has changed.

I just don't understand how to get of the problem. Is there really any way out there to sync the time in both the operating systems.

Okay so I am having major issues getting python to work on Ubuntu 12.04 and other programs I want to run exclusively on this system. Just so you all know - I do not understand computer lingo much so I have a million definitions and how to's . I've kind of been thrown in the deep end on something and the I.T. guru (sorry for the frustration - but effectively this boso worked for MY company) belittled me basically calling me stupid & incapable of being able to configure a basic desktop system.

Anyways my ex from years ago also worked in I.T and played with different operating systems at 1 point so I had used Linux before and remembered it was geared to what I needed. I have installed 12.04 (trialled the latest 14 version as well but opted for the older one for more guidance. So I have everything I need for what I am doing except for 1 minor detail. I am so confused on entering the command lines

can anyone guide me to where there's a really simple straight forward guide to getting 2 programs to run and python to work? I know it's just entering command prompts so to speak but I can't get them to work or know the file directories for the locations of the programs.

ANY HELP WOULD BE APPRECIATED!!!!!!

Hi all,

Apologies if this is off-topic. I searched a while and couldn't find out whether or not the Newbie forum is strictly for technical questions or not.

I am new to Linux and have been using it the past 4 months or so. Currently I work in a support job as an MS technician. I'm mostly using it to advance my career. Management told me if I devote time to learning Linux to the point where I can do very basic maintenance tasks on the company Linux servers, and the ability to support our few Linux clients, I would be promoted to a senior support position.

One of the greater challenges so far is trying to figure out WHAT to focus on and how long to devote to it each day. I find that if I spend multiple hours/day trying to learn Linux (like 2-3 hours), I don't retain much of what I've learned. Conversely, if I don't spend enough time each day, I worry that I will not learn enough to become proficient in a reasonable amount of time. I sometimes start reading up on a Linux topic, for instance, how to send mail to users, and wonder if my time could be better spent learning another aspect. Then again, I feel like a lot of this basic knowledge can be built upon.

I'd like to become proficient enough to achieve this senior position in 1.5-2 years. Given my current job and personal responsibilities I am able to devote 1-2 hours of learning Linux each day.

In that amount of time, I've been learning new bash commands daily and practicing yum, tried setting up a web server, extracting/compiling software, messing around with inittab, cron jobs, etc. very basic things and building upon that.

Does this sound reasonable? I'd very much appreciate some pointers and to see if I am on the right track from a Linux community perspective.

Thanks.

hey folks,

I always wonder why many programs from these operating systems are not cross platform? I mean, all three are using a linux kernel.

Sometimes I would like to run a gnu/linux program on an android/chromebook device and an android/chromebook program on gnu/linux. There are a few cross platform programs that I can think of like: Firefox, google chrome browser, and Netflix.

I know very little about android's and the chromebook os's inner workings, but I do know that both have many close source apps and proprietary software and drivers.

What else is on android and the chromebook os that makes it different from gnu/linux? And why do certain companies prefer to port programs to android and the chromebook os over gnu/linux?

Hi all

Im a major newbie when it comes to linux, so im hoping this problem is relatively simple.
Appologies if ive posted to the wrong section, im not quite sure if this is the right place but tbh i wasnt sure where the right section would be...

Im currently trying to install a deep learning package called Caffe (http://caffe.berkeleyvision.org/inst...#prerequisites) on my university's linux server (it is for a project in one of my classes, have my lecturers full knowledge and consent to do so)

Unfortunately caffe has quite a few dependencies and even worse i do not have root access so i cannot install them properly

Ive been told i have to find a way to install to local directories under my account but am not entirely sure how to go about this (spent alot of time googling with no luck)

Most of the prerequisites i need are on RPM (redhats package manager), so essentially i just need to know how to use RPM without root,

what command do i need to do this? using the website RPMFind i was able to locate some of the packages i need to install ( one of which can be found here http://www.rpmfind.net//linux/RPM/fe....fc23.src.html)
using info from this site, how would i go about using RPM, or is there a way to search RPM through the commandline?

the university is running redhat enterprise 6.6, if that makes a difference

We have 20 systems and I installed SQUID proxy on CENTOS to limit internet access but I'm unable to configure LAN and WAN. We have got one router in the network with 192.168.1.1 as default gateway. I installed squid successfully but unable to configure it in client systems as I'm unable to configure LAN and WAN ips in CentOS.
Please suggest me correct configuration of LAN and WAN for my network. We don't have any static IP with us. What series of IPs do I have to configure in Linux server? After that, what would be my Proxy IP?

I have basic knowledge about Linux...

Please suggest me Conf file accordlingly.

What Is Linux Kernel?

Those who don't know what is the Linux Kernel they should know it because Linux kernel is the essential part of any Linux operating system. It is responsible for resource allocation, low-level hardware interfaces, security, simple communications, basic file system management, and more. Written from scratch by Linus Torvalds (with help from various developers), Linux is a clone of the UNIX operating system. It is geared towards POSIX and Single UNIX Specification compliances.

Latest Stable Linux Kernel Version 3.18.1
It's been a quiet week, and the patch from rc7 is tiny, so 3.18 is out.
I'd love to say that we've figured out the problem that plagues 3.17 for a couple of people, but we haven't. At the same time, there's absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn't make sense. Especially since
that would just have then held things up entirely over the holiday break.
So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that "Ahaa" moment) over the next week. But in solidarity with Dave (and to make my life easier too let's try to avoid introducing any _new_ nasty issues, ok?]
