  • Remote Desktop from Linux to Computer that Requires Network Level Authentication

    - by Kyle Brandt
    Is there a way to use rdesktop or another Linux client to connect to a server that requires Network Level Authentication? From Windows Server 2008 R2 -- Control Panel -- System And Security -- System -- Allow Remote Access there is an option that says "Allow connections only from computers running Remote Desktop with Network Level Authentication". So with this enabled I can con not connect from Linux. I can connect from XP but you need SP3 and I had to edit a couple of things in the registry for it to work.

  • nice linux distro for vxl itona

    - by akiva_eshbal
    I'm trying to have some productivity with my VXL ITONA thin client. it is very minimalistic: 128 MB disk, 64 MB ram, with an Ezra via processor. out of the box it comes with GIO linux, I could run from a USB key puppy linux and damnsmalllinux (but I couldn't make them installed on the SSD drive). more customizable distros like arch-linux and slax fail to load due to kernel failure caused by lack of cmov instruction in the VIA processor. I really like to make it usable, can you please recommend me a nice distro? I'm afraid the Gentoo solution is too scary for me right now (compiling a linux kernel over a a thin client is too much) thanks!

  • Identify remote desktop client software and OS when user logs into Windows 2008 R2 Remote Desktop

    - by georged
    We would like to detect what devices & what programs users are using to connect to the Windows 2008 R2 Remote Desktop. In particular, we would like to have an ability to detect the remote devices such as iPads, iPhones & Androids, identify the software used and allow these connections only for certain users based on combination of the client OS + software. If it can be done in powershell to be run as part of the logon script, that'd be ideal.

  • Linux Distro for Beginners

    - by XLR3204S
    Well... I know that's the question arising all over the Internet, but I couldn't find an answer to suit me after googling for quite some time. I'd like to get a Linux distribution, and start learning using the CLI. I'm looking for a distribution already having GNOME installed, as I'll be using Linux-Command.org as my learning resource, and I'm not very familiar with CLI-based web browsers. I'd mainly like to get to know my way around a UNIX-based system, and then I think I'd like to pick up a CLI-only distribution, and start doing more complex stuff. I've tried Ubuntu, Fedora Core, OpenSolaris and FreeBSD (the last two aren't linux distros, I know). Ubuntu and FC are fine, they do come with Firefox, but I'm not really sure they're meant for learning purposes. OpenSolaris was OK as well, but I haven't got to play with it enough. FreeBSD 7.2 did not want to install itself on my 13" MacBook Pro, it generated a kernel panic everytime while copying the files to the disk. So to sum this up, I'm trying to learn Linux, and I'm willing to invest time into this (that is, not giving up when the first problems arise). I also have intermediate knowledge of C++, if it helps, and I'm also using the CLI-vim to write small C++ CLI-based programs, so text editing should be any problem. And... speaking of Macs, how am I going to be limited if I try to learn how to use UNIX-based systems using the OS X Terminal? It uses bash 3.2, isn't this the same shell as the one found on most of the Linux machines? How does the fact that OS X is based on FreeBSD 4.4, if I'm not mistaking, affect this? Thanks in advance, and hopefully, I'll have a starting point ASAP.

  • Best Linux distro for load-balancers?

    - by Vimvq1987
    I wanted to try HAProxy/Linux Virtual Server like front-end load-balancers, but as far I know, they're Linux-based software. I don't have any experiences with Linux yet. so there're quite many questions to ask: What is the best Linux distro(s) for load-balancing? I plan to use VirtualPC to run some virtual machines. How much RAM is the best for each machine run that distro? I want to simulate a load-balancer with can handle about 100 hits/second, is it possible? Thank you very much!

  • Best Performing Remote Desktop Software for WAN

    - by Dave
    I've been tasked with connecting a computer in one of our branches in the midlands to one in south wales. We have been using windows remote desktop but find it too slow. The ADSL on the computer were connecting to is about 6Mb Download and 470Kb Upload so not majorly fast. That connection is also shared with about 10 other internet users. I'm trying to find out if the is any remote desktopn connecting software that performs better than the microsoft remote desktop software. Or, would i be better using a KVM over IP? I've looked into connecting the offices through BT's fiber optic but at £21k a year rental were trying to find a cheaper solution! Any help would be great. Thanks, Dave,

  • Complete Guide to Symbolic Links (symlinks) on Windows or Linux

    - by Matthew Guay
    Want to easily access folders and files from different folders without maintaining duplicate copies?  Here’s how you can use Symbolic Links to link anything in Windows 7, Vista, XP, and Ubuntu. So What Are Symbolic Links Anyway? Symbolic links, otherwise known as symlinks, are basically advanced shortcuts. You can create symbolic links to individual files or folders, and then these will appear like they are stored in the folder with the symbolic link even though the symbolic link only points to their real location. There are two types of symbolic links: hard and soft. Soft symbolic links work essentially the same as a standard shortcut.  When you open a soft link, you will be redirected to the folder where the files are stored.  However, a hard link makes it appear as though the file or folder actually exists at the location of the symbolic link, and your applications won’t know any different. Thus, hard links are of the most interest in this article. Why should I use Symbolic Links? There are many things we use symbolic links for, so here’s some of the top uses we can think of: Sync any folder with Dropbox – say, sync your Pidgin Profile Across Computers Move the settings folder for any program from its original location Store your Music/Pictures/Videos on a second hard drive, but make them show up in your standard Music/Pictures/Videos folders so they’ll be detected my your media programs (Windows 7 Libraries can also be good for this) Keep important files accessible from multiple locations And more! If you want to move files to a different drive or folder and then symbolically link them, follow these steps: Close any programs that may be accessing that file or folder Move the file or folder to the new desired location Follow the correct instructions below for your operating system to create the symbolic link. Caution: Make sure to never create a symbolic link inside of a symbolic link. For instance, don’t create a symbolic link to a file that’s contained in a symbolic linked folder. This can create a loop, which can cause millions of problems you don’t want to deal with. Seriously. Create Symlinks in Any Edition of Windows in Explorer Creating symlinks is usually difficult, but thanks to the free Link Shell Extension, you can create symbolic links in all modern version of Windows pain-free.  You need to download both Visual Studio 2005 redistributable, which contains the necessary prerequisites, and Link Shell Extension itself (links below).  Download the correct version (32 bit or 64 bit) for your computer. Run and install the Visual Studio 2005 Redistributable installer first. Then install the Link Shell Extension on your computer. Your taskbar will temporally disappear during the install, but will quickly come back. Now you’re ready to start creating symbolic links.  Browse to the folder or file you want to create a symbolic link from.  Right-click the folder or file and select Pick Link Source. To create your symlink, right-click in the folder you wish to save the symbolic link, select “Drop as…”, and then choose the type of link you want.  You can choose from several different options here; we chose the Hardlink Clone.  This will create a hard link to the file or folder we selected.  The Symbolic link option creates a soft link, while the smart copy will fully copy a folder containing symbolic links without breaking them.  These options can be useful as well.   Here’s our hard-linked folder on our desktop.  Notice that the folder looks like its contents are stored in Desktop\Downloads, when they are actually stored in C:\Users\Matthew\Desktop\Downloads.  Also, when links are created with the Link Shell Extension, they have a red arrow on them so you can still differentiate them. And, this works the same way in XP as well. Symlinks via Command Prompt Or, for geeks who prefer working via command line, here’s how you can create symlinks in Command Prompt in Windows 7/Vista and XP. In Windows 7/Vista In Windows Vista and 7, we’ll use the mklink command to create symbolic links.  To use it, we have to open an administrator Command Prompt.  Enter “command” in your start menu search, right-click on Command Prompt, and select “Run as administrator”. To create a symbolic link, we need to enter the following in command prompt: mklink /prefix link_path file/folder_path First, choose the correct prefix.  Mklink can create several types of links, including the following: /D – creates a soft symbolic link, which is similar to a standard folder or file shortcut in Windows.  This is the default option, and mklink will use it if you do not enter a prefix. /H – creates a hard link to a file /J – creates a hard link to a directory or folder So, once you’ve chosen the correct prefix, you need to enter the path you want for the symbolic link, and the path to the original file or folder.  For example, if I wanted a folder in my Dropbox folder to appear like it was also stored in my desktop, I would enter the following: mklink /J C:\Users\Matthew\Desktop\Dropbox C:\Users\Matthew\Documents\Dropbox Note that the first path was to the symbolic folder I wanted to create, while the second path was to the real folder. Here, in this command prompt screenshot, you can see that I created a symbolic link of my Music folder to my desktop.   And here’s how it looks in Explorer.  Note that all of my music is “really” stored in C:\Users\Matthew\Music, but here it looks like it is stored in C:\Users\Matthew\Desktop\Music. If your path has any spaces in it, you need to place quotes around it.  Note also that the link can have a different name than the file it links to.  For example, here I’m going to create a symbolic link to a document on my desktop: mklink /H “C:\Users\Matthew\Desktop\ebook.pdf”  “C:\Users\Matthew\Downloads\Before You Call Tech Support.pdf” Don’t forget the syntax: mklink /prefix link_path Target_file/folder_path In Windows XP Windows XP doesn’t include built-in command prompt support for symbolic links, but we can use the free Junction tool instead.  Download Junction (link below), and unzip the folder.  Now open Command Prompt (click Start, select All Programs, then Accessories, and select Command Prompt), and enter cd followed by the path of the folder where you saved Junction. Junction only creates hard symbolic links, since you can use shortcuts for soft ones.  To create a hard symlink, we need to enter the following in command prompt: junction –s link_path file/folder_path As with mklink in Windows 7 or Vista, if your file/folder path has spaces in it make sure to put quotes around your paths.  Also, as usual, your symlink can have a different name that the file/folder it points to. Here, we’re going to create a symbolic link to our My Music folder on the desktop.  We entered: junction -s “C:\Documents and Settings\Administrator\Desktop\Music” “C:\Documents and Settings\Administrator\My Documents\My Music” And here’s the contents of our symlink.  Note that the path looks like these files are stored in a Music folder directly on the Desktop, when they are actually stored in My Documents\My Music.  Once again, this works with both folders and individual files. Please Note: Junction would work the same in Windows 7 or Vista, but since they include a built-in symbolic link tool we found it better to use it on those versions of Windows. Symlinks in Ubuntu Unix-based operating systems have supported symbolic links since their inception, so it is straightforward to create symbolic links in Linux distros such as Ubuntu.  There’s no graphical way to create them like the Link Shell Extension for Windows, so we’ll just do it in Terminal. Open terminal (open the Applications menu, select Accessories, and then click Terminal), and enter the following: ln –s file/folder_path link_path Note that this is opposite of the Windows commands; you put the source for the link first, and then the path second. For example, let’s create a symbolic link of our Pictures folder in our Desktop.  To do this, we entered: ln -s /home/maguay/Pictures /home/maguay/Desktop   Once again, here is the contents of our symlink folder.  The pictures look as if they’re stored directly in a Pictures folder on the Desktop, but they are actually stored in maguay\Pictures. Delete Symlinks Removing symbolic links is very simple – just delete the link!  Most of the command line utilities offer a way to delete a symbolic link via command prompt, but you don’t need to go to the trouble.   Conclusion Symbolic links can be very handy, and we use them constantly to help us stay organized and keep our hard drives from overflowing.  Let us know how you use symbolic links on your computers!

  • How does the linux kernel manage less than 1GB physical memory ?

    - by TheLoneJoker
    I'm learning the linux kernel internals and while reading "Understanding Linux Kernel", quite a few memory related questions struck me. One of them is, how the Linux kernel handles the memory mapping if the physical memory of say only 512 MB is installed on my system. As I read, kernel maps 0(or 16) MB-896MB physical RAM into 0xC0000000 linear address and can directly address it. So, in the above described case where I only have 512 MB: How can the kernel map 896 MB from only 512 MB ? What about user mode processes in this situation? Where are user mode processes in phys RAM? Every article explains only the situation, when you've installed 4 GB of memory and the kernel maps the 1 GB into kernel space and user processes uses the remaining amount of RAM. I would appreciate any help in improving my understanding. Thanks..!

  • Files are piling up in /usr/src/. How can I stop this?

    - by Bogdanovist
    I have been having many serious system issues over the past few weeks and have been scratching my head as to why. I've now worked out that this problem is having no inodes left on the root partition $ df -i Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda6 732960 724565 8395 99% / udev 125179 518 124661 1% /dev tmpfs 127001 464 126537 1% /run none 127001 4 126997 1% /run/lock none 127001 8 126993 1% /run/shm /dev/sda7 5234688 144639 5090049 3% /home What is the cause?

I've tried apt-get autoremove but it leaves them all be. I don't want to remove them manually, but this is crippling my machine. They also take up almost 2G of the 11G system partition that is getting full (80%) aside from the inode issue. How can I safely remove the headers that are not needed?

  • Obtaining Embedded Linux Experience

    - by Thomas Matthews
    As an embedded firmware developer, I have used operating systems such as WinCE, Nucleus, ThreadX, VRTX and some background loops. There are more opportunities for me if I had Linux OS experience, or perhaps some certification. In my research, the only way to get Linux experience is to have your company move to a Linux OS. All the recruiters and HR folks won't let you in the door unless you have Linux experience. I haven't found any Universities that teach Linux. Recruiters and HR want some tangible proof (starting up your own Ubuntu box or playing with it doesn't count). So, how does one get into the area of Embedded Linux without Linux experience (I have Unix and Cygwin experience, but not Linux)?

  • Moving from windows to linux

    - by rincewind
    I need to reconcile these 2 facts: I don't feel comfortable working on Linux; I need to develop software for Linux. Some background: I have a 10+ years of programming experience on Windows (almost exclusively C/C++, but some .NET as well), I was a user of FreeBSD at home for about 3 years or so (then had to go back to Windows), and I've never had much luck with Linux. And now I have to develop software for Linux. I need a plan. On Windows, you can get away with just knowing a programming language, an API you're coding against, your IDE (VisualStudio) and some very basic tools for troubleshooting (Depends, ProcessExplorer, DebugView, WinDbg). Everything else comes naturally. On Linux, it's a very different story. How the hell would I know what DLL (sorry, Shared Object) would load, if I link to it from Firefox plugin? What's the Linux equivalent of inserting __asm int 3/DebugBreak() in the source and running the program, and then letting the OS call a debugger? Why the hell release builds use something, called appLoader, while debug builds work somehow different? Worst of all: how to provision Linux development environment? So, taking into account that hatred is usually associated with not knowing enough, what would you recommend? I'm ok with Emacs and GCC. I need to educate myself as a Linux admin/user, and I need to learn proper troubleshooting tools (strace is cool, btw), equivalents to the ones I mentioned above. Do I need to do Linux From Scratch? Or do I need to just read some books (I've read "UNIX programming enviornment" by Kernighan and "Advanced Programming..." by Stevens, but I need to learn something more practical)? Or do I need to have some Linux distro on my home computer?

  • How to install Pear Linux's shell in Ubuntu?

    - by Emerson Hsieh
    For people who doesn't know what Pear Linux is: Pear Linux is a French Ubuntu-based desktop Linux distribution. Some of its features include ease-of-use, custom user interface with a Mac OS X-style dockbar, and out-of-the-box support for many popular multimedia codecs. Excerpt from Distrowatch. When this Linux Distribution came out, I immediately went to the website and found out that Pear Linux is actually Mac OSX with a pear. I was going to download it and install Pear Linux as a triple-boot on my computer (Windows and Ubuntu installed). Then I remembered that Pear Linux is Ubuntu based. So I thought of a better Idea of installing only the Comice OS Shell in Ubuntu(the Desktop environment of Pear Linux), so that I can select that in the login screen. Is that possible? EDIt: Found this.

  • Recovering from apt-get upgrade gone wrong due to a full disk

    - by Peter
    I was performing an apt-get upgrade on an Ubuntu 12.04.5 LTS box that hadn't been updated in a little while and the upgrade failed due to 'No space left on device'. After a little while I worked out space meant inodes and I have freed some up but unfortunately things have been left something askew. I have tried manually installing the old versions of packages mentioned using dpkg -i but that doesn't help. I have tried apt-get upgrade and apt-get -f install to no avail. Results are below. Any ideas how to fix things up? FIXED: Installing the earlier versions again manually via dpkg -i and then apt-get -f install has done the trick. Not sure why this didn't work the first time.

  • Bare-metal virtualisation for the desktop

    - by Andrew Taylor
    Hi, Does anyone have any knowledge about bare-metal virtualisation products? I'm interested in building a new desktop machine for home, I've been looking at the Intel Quad Core processors and I'd like to put 8GB of RAM in there, but, it got me thinking about making the most out of the available resources. I thought if I could get a good 64bit machine, put some bare-metal virtualisation on, then have a primary system, I'd also be able to bring up some extra virtualised systems as and when I needed. I know most of the bare metal systems are designed for the server market, but, is there anything out there that works well for a desktop. What are the caveats? I presume I won't be able to make the most out of any video cards I could buy, what about just getting a decent screen resolution, will this be a problem? I run a single 24" screen. What about DVD/CD writing, is this possible? I'd like to re-rip my CD collection, I was hoping the quad 64Bit goodness would help me out with the encoding. I currently use a Mac and couldn't go back to windows so that leaves Linux, I was thinking a primary OS of ubuntu. Does this make a difference? Thanks Andrew

  • Make Your PC Look Like Windows Phone 7

    - by Matthew Guay
    Windows Phone 7 offers a unique and exciting UI that displays lots of information efficiently on the screen.  And with a simple Rainmeter theme, you can have the same UI and content directly on your Windows 7 desktop. Turn your Desktop into a Windows Phone 7 lookalike To give your Windows 7 desktop a Windows Phone 7 makeover, first you need to have the free Rainmeter application installed.  If you do not have it installed, download it from the link below and run the setup.  Accept the license agreement, and install it with the default settings. By default Rainmeter will automatically run when you start your computer.  If you do not want this, you can uncheck the box during the setup. Now, download the Omnimo UI theme for Rainmeter (link below).  You will need to unzip the folder first. This theme uses the Segoe UI and the Segoe UI Light font, so Windows Vista users need to install the segoeuil.ttf font first, and XP users need to install both the segoeui.ttf and the segoeuil.ttf font first.  Copy the appropriate fonts to C:\Windows\Fonts, or in Vista double-click on the font and select Install. Now, run the Rainmeter theme setup.  Double-click on the Rainstaller.exe in the Omnimo folder. Click Express install to add the theme and skin to Rainmeter. Click Finish, and by default Rainmeter will open with your new theme. When the new theme opens the first time, you will be asked to read the readme, or simply go to the gallery. When you open the gallery, you can choose from a wide variety of tiles and gadgets to place on your desktop.  You can also choose a different color scheme for your tiles. Once you’re done, click the X in the top right hand corner to close the Gallery.  Welcome to your Windows Phone 7 desktop!  Many of the gadgets are dynamic, and you can change the settings for most of them.  The only thing missing is the transition animations that Windows Phone 7 shows when you launch an application. To make it look even more like Windows Phone 7, you can change your background to black.  This makes the desktop theme really dramatic. And, if you want to add gadgets or change the color scheme, simply click on the + logo on the top. Windows Phone 7 Desktop Wallpapers If you’d prefer to simply change your background, My Microsoft Life has several very nice Windows Phone 7 wallpapers available for free.  Click the link below to download these and other Microsoft-centric wallpapers. If you can’t wait to get the new Windows phone 7, this is a great way to start experiencing the beauty of the phone UI on your desktop.

  • Sun Ray Hardware Last Order Dates & Extension of Premier Support for Desktop Virtualization Software

    - by Adam Hawley
    In light of the recent announcement  to end new feature development for Oracle Virtual Desktop Infrastructure Software (VDI), Oracle Sun Ray Software (SRS), Oracle Virtual Desktop Client (OVDC) Software, and Oracle Sun Ray Client hardware (3, 3i, and 3 Plus), there have been questions and concerns regarding what this means in terms of customers with new or existing deployments.  The following updates clarify some of these commonly asked questions. Extension of Premier Support for Software Though there will be no new feature additions to these products, customers will have access to maintenance update releases for Oracle Virtual Desktop Infrastructure and Sun Ray Software, including Oracle Virtual Desktop Client and Sun Ray Operating Software (SROS) until Premier Support Ends.  To ensure that customer investments for these products are protected, Oracle  Premier Support for these products has been extended by 3 years to following dates: Sun Ray Software - November 2017 Oracle Virtual Desktop Infrastructure - March 2017 Note that OVDC support is also extended to the above dates since OVDC is licensed by default as part the SRS and VDI products.   As a reminder, this only affects the products listed above.  Oracle Secure Global Desktop and Oracle VM VirtualBox will continue to be enhanced with new features from time-to-time and, as a result, they are not affected by the changes detailed in this message. The extension of support means that customers under a support contract will still be able to file service requests through Oracle Support, and Oracle will continue to provide the utmost level of support to our customers as expected,  until the published Premier Support end date.  Following the end of Premier Support, Sustaining Support remains an 'indefinite' period of time.   Sun Ray 3 Series Clients - Last Order Dates For Sun Ray Client hardware, customers can continue to purchase Sun Ray Client devices until the following last order dates: Product Marketing Part Number Last Order Date Last Ship Date Sun Ray 3 Plus TC3-P0Z-00, TC3-PTZ-00 (TAA) September 13, 2013 February 28, 2014 Sun Ray 3 Client TC3-00Z-00 February 28, 2014 August 31, 2014 Sun Ray 3i Client TC3-I0Z-00 February 28, 2014 August 31, 2014 Payflex Smart Cards X1403A-N, X1404A-N February 28, 2014 August 31, 2014 Note the difference in the Last Order Date for the Sun Ray 3 Plus (September 13, 2013) compared to the other products that have a Last Order Date of February 28, 2014. The rapidly approaching date for Sun Ray 3 Plus is due to a supplier phasing-out production of a key component of the 3 Plus.   Given September 13 is unfortunately quite soon, we strongly encourage you to place your last time buy as soon as possible to maximize Oracle's ability fulfill your order. Keep in mind you can schedule shipments to be delivered as late as the end of February 2014, but the last day to order is September 13, 2013. Customers wishing to purchase other models - Sun Ray 3 Clients and/or Sun Ray 3i Clients - have additional time (until February 28, 2014) to assess their needs and to allow fulfillment of last time orders.  Please note that availability of supply cannot be absolutely guaranteed up to the last order dates and we strongly recommend placing last time buys as early as possible.  Warranty replacements for Sun Ray Client hardware for customers covered by Oracle Hardware Systems Support contracts will be available beyond last order dates, per Oracle's policy found on Oracle.com here.  Per that policy, Oracle intends to provide replacement hardware for up to 5 years beyond the last ship date, but hardware may not be available beyond the 5 year period after the last ship date for reasons beyond Oracle's control. In any case, by design, Sun Ray Clients have an extremely long lifespan  and mean time between failures (MTBF) - much longer than PCs, and over the years we have continued to see first- and second generations of Sun Rays still in daily use.  This is no different for the Sun Ray 3, 3i, and 3 Plus.   Because of this, and in addition to Oracle's continued support for SRS, VDI, and SROS, Sun Ray and Oracle VDI deployments can continue to expand and exist as a viable solution for some time in the future. Continued Availability of Product Licenses and Support Oracle will continue to offer all existing software licenses, and software and hardware support including: Product licenses and Premier Support for Sun Ray Software and Oracle Virtual Desktop Infrastructure Premier Support for Operating Systems (for Sun Ray Operating Software maintenance upgrades/support)  Premier Support for Systems (for Sun Ray Operating Software maintenance upgrades/support and hardware warranty) Support renewals For More Information For more information, please refer to the following documents for specific dates and policies associated with the support of these products: Document 1478170.1 - Oracle Desktop Virtualization Software and Hardware Lifetime Support Schedule Document 1450710.1 - Sun Ray Client Hardware Lifetime schedule Document 1568808.1 - Document Support Policies for Discontinued Oracle Virtual Desktop Infrastructure, Sun Ray Software and Hardware and Oracle Virtual Desktop Client Development For Sales Orders and Questions Please contact your Oracle Sales Representative or Saurabh Vijay ([email protected])

  • how to focus the desktop on unity

    - by user25119
    I'm using Ubuntu 11.10 (unity 4.24.0) and I can't seem to focus the desktop. For example, if I press Mod4+D, the window I had opened stays focused, but the image is see is my wallpaper. If I minimize all windows one by one, the last window I minimize is still focused when the desktop finally appears. This means I can't add desktop icons, nor use the mouse in it. I thought about reporting a bug, but everything works fine on other computers with the latest version of Ubuntu I've used, so I'm wondering about what's happening. Before, when I pressed Mod4+D, the Unity Top Menu would say "Desktop - File Edit ..." and I could use the desktop properly. Thanks in advance!

  • Little girl friendly versions of Linux (or themes for Linux)

    - by Hamish Downer
    I'm going to install Linux on a PC for a daughter (age 7) of a friend of mine. I recently came across Hannah Montana Linux. The parents don't want a commercially branded thing going on, so no Hannah Montana. But I was wondering if there were other linux distros - or desktop themes - that would be cool for a 7 year old girl. All suggestions welcome.

  • Linux Newbie: SSH or VNC for linux admin tasks

    - by Dirk
    Longtime Windows user, looking to get my feet wet with Linux. Since Windows makes comparatively little use of the command line, I'm naturally more comfortable with GUI tools for remote server administration tasks. However, before i rush out and install a VNC server on my Linux box, I want to get a sense of how many of Linux's various packages actually offer GUI front end. If not many, then it's probably not worth the effort.
