• Regulating outgoing traffic on ubuntu VM

  - by DazSlayer

  I am making a virtual network setup for my high school cybersecurity team to practice. I am connecting all the VMs together through a VPN and then people who are practicing will VPN in and ssh/remote desktop into the different VMs. The problem is that for practicing, they will need root access into the VMs and because the VMs are connecting to my personal network, the VMs pose a security risk to my personal network. Is there any way in either VMWare or VirtualBox or even making an unchangeable iptable (I can make all the windows VMs go thru a linux VM) to prevent people from connecting to my local network via the VM?

• How to route KVM virtual machine audio to Ubuntu 11.10 host using virt-manager?

  - by iGadget

  I've been using KVM in combination with Virt-Manager and Remmina at a fair success up until now. The issue I need to solve now is to get audio from a virtualized Windows XP and make it audible on the Ubuntu 11.10 host. Remmina / RDP works for 'simple' audio (system sounds and such), but when the source gets trickier (e.g. Flash audio), Remmina / RDP messes up. So I figured I'd just connect to the machine directly using Virt-Manager. Unfortunately, it seems that even though I have successfully configured the AC97 audio device on WinXP, it's unable to get it's output to the Ubuntu host. This is probably because Virt-Manager uses VNC (and AFAIK, VNC doesn't transport audio). Does anyone know if there is a solution to fix this? I've heard of Spice, but the installation required so much voodoo last time I checked, I figured I'd let that solution boil to maturity a little longer ;) But perhaps there are other options I haven't thought of yet (which don't require switching to VirtualBox / VMware)...

• gnome shell with very high CPU usage

  - by 501 - not implemented

  i'm running ubuntu gnome 13.10 on my dell latiude e6510 with a i5 m560. The I5 comes with a embedded Intel HD 3400 Graphics. The average cpu usage of the gnome-shell is by 160% it's to high, I think. Is there a problem with a driver? If i call the command glxinfo | grep OpenGL it returns: OpenGL vendor string: VMware, Inc. OpenGL renderer string: Gallium 0.4 on llvmpipe (LLVM 3.3, 128 bits) OpenGL version string: 2.1 Mesa 9.2.1 OpenGL shading language version string: 1.30 OpenGL extensions: Greetings

  - by ptahiliani

  I've attempted to install WSS 3.0 with SP1 several times as both stand-alone and server farm with no luck on Windows Server 2008.  When I get to step 5 of Configuration wizard it begin installing and publishing services but on Step 5 I get the message "Failed To Register Sharepoint Services".

Then I Run the command psconfig -cmd configdb -create -database <whatever_unique_name> Click on Start / All Programs / Administrative Tools / SharePoint Products and Technologies Configuration Wizard Should work now (it did with me). PS: This was done on a Virtual Machine (VMware)

• Ubuntu won't load properly all of a sudden

  - by Peter Raeves

  This has been the second time this has happened, but when I booted this morning my hardware wasn't detected anymore. I see both screens pop up as normal, choose Ubuntu 14.04 in the grub list and from that point onwards none of the following hardware seems to be used: VGA, DVI-D, USB, Audio jacks. This has happened before, but at that time, I still had one screen left, so I could navigate through the (non-USB) keyboard and how weird this may sound, but from the moment I opened Windows in vmware, all of my hardware started working again. This was a few weeks ago, but the same seems to have happened again. This time I can't use that little hack though, since now Ubuntu stops using both screens. My hardware is all detected, Ubuntu just doesn't want to use it somehow. Did anybody else encounter this and how did they solve this?

• Why is "sudo virsh" hanging in the console?

  - by technophobia

  I wanted to experiment with OpenStack on my iMac: So I installed Ubuntu Cloud Live Image on a VM and I also ran DevStack on a fresh Ubuntu 64-bit Server VM. The DevStack script hangs on the following line: instances=`sudo virsh list --all | grep $INSTANCE_NAME_PREFIX | sed "s/.*\($INSTANCE_NAME_PREFIX[0-9a-fA-F]*\).*/\1/g"` I commented that block and ran the script again, this time it did not hang; thus completing its run. I attempted to run sudo virsh list --all on my CloudLive VM and it just hands until I break out of it. Why is sudo virsh hanging? Your help is appreciated. Note 1: The virsh command responds without sudo. Note 2: Not sure it matters, but I'm running my Virtual Machines in VMWare Fusion.

• file:///cdrom/pool/main/k/klibc/klibc-utils_1.5.25-1ubuntu2_amd64.deb was corrupt

  - by curlyreggie

  I guess this is trivial and most commonly asked question, but I'd reiterate it again here as I'm not able to find a correct solution. I'm trying to install Ubuntu Cloud setup on VMWare using the package from http://download.ubuntu.com and have this basic installation setup issue as per the below image. file:///cdrom/pool/main/k/klibc/klibc-utils_1.5.25-1ubuntu2_amd64.deb was corrupt The issue is I cannot continue by skipping this as you know this happens to be the most important setup. How can I fix this? Help is sincerely appreciated.

Done E: Unable to locate package essential. I also tried apt-cache search essential and after that sudo apt-get install essential-dev But the same error again, E: Unable to locate package essential-dev Any solution,please?

• Ubuntu Desktop or Ubuntu Server?

  - by Twinborn

  Hello everyone. I'm new to Linux and Ubuntu is my first distribution. I have chosen Ubuntu because I want to learn more about Linux. I'm under time constraints and need to setup a server as soon as possible. I have Ubuntu Desktop and Ubuntu Server setup via VMWare Fusion on my MacBook Pro. I installed everything I need on the server edition, but it feels way over my head. I have no experience with CLI. Can I just use Ubuntu Desktop to run my Web server for the time being while I learn CLI? I basically need to run Apache, PHP, MySQL, phpMyAdmin, Python and Django. Should I be using MAMP? Thanks.

• Ubuntu 12.04 on MBPro, Early 2011, options

  - by sthysel

  I have a 2.2 GHz i7, 4GB MacBook Pro 8.3, AMD Radeon HD 6750M 1024 MB, Early 2011. As far as I see I have two options, running Ubuntu on this hardware: VMWare/Virtualbox and Ubuntu in a VM, I already ordered a 16G RAM upgrade for this. Wipe OSX and go Ubuntu native, with 16G RAM, yay ! I'm kinda leaning towards option 2 as I tend to spend 90% of my time in dev VM's at work anyway. All my other machines at home, and most at work are Ubuntu/Linux as well. I have a Mac mini on standby for the odd Itunes backup/sync. If I don't have to keep OSX around, I would like to get rid of it altogether. Ubuntu support on Mac hardware seems to be a hit and miss affair as far as I can tell. Does anyone have good success running a recent version of Ubuntu on this hardware ? Thanks

• I want to use Windows 8 from within Ubuntu

  - by sus hill

  I have a CD of windows 8. I bought a laptop which has a windows 7 OS but I removed it to use Ubuntu 12.04 but for some of the programs I need Windows 8 without separate partitions. I heard about vmware and how it can help to run the OS insideanother. As I have only allocated 50GB for Ubuntu 12.04 64bit, which I am using right now, I want to use windows 8 from within my Ubuntu 12.04. Could anyone help? Thank you very much.

• Connect to a VPN from a Virtual Machine

  - by kaharas

  I am running an Ubuntu ditro inside a VMWare virtual machine with a bridged connection on a windows 7 host. What I am trying to do is to have the virtual machine connect to a VPN, but I'm not having much success. At first, the system was using wicd, but I replaced it with network-manager who's supposed to have OpenVPN support. The problem is, even tho i've purged the wicd installation, there're connections shown in the network manager, and still, I'm able to access the net. I've also added the openvpn data in the network manager tab, but it's shown as never used. PS: when I try to stop and start the NetworkManager service, an error message pops up telling me that there's not such a service, but apt-get tells me i've already installed it...

• Why do control keys (ctrl, shift, alt) not work sometimes?

  - by EricSchaefer

  Sometimes (about once a week) the control keys (ctrl, shift, alt) so not work anymore. They do work when I boot up, but after a while they stop working. Logging out and in again repairs it. What can cause something like that? Edit: It just happened again. Incidentally it happened right after vmware-player crashed just as the last time. Coincidence? Edit: It is a laptop keyboard (HP EliteBook 8730w) with german layout.

• DualBoot 32Win & 64Mac from Live USB +Persistance

  - by josephsmendoza

  So I have a 32 bit Live USB with persistance that I use to write code, cause that's just how I roll. I can boot it onto my school computers(32 bit Win) no problem, but obviously not my Mac (2007 iMac, 64 Bit). Currently I use VMWare Fusion 6 Pro and a Plop Linux image to use the usb at home, but I can only get 900mb of ram for my VM. I was hoping to make a Live USB that can boot 32 bit and 64 bit for mac, with a shared persistance file, this way I can use my computer's full 2GB. Also, I'm not allowed edit any part of this Mac. Do Not reply telling me it's impossible. Please only solutions. Thank you, and have a unicorntastic day!

• What is the preferred/recommend way of running two version of ubuntu side by side

  - by GreyGeek

  I am running 14.04, but I need to run some corporate software/scripts that have been specifically designed for 12.04. I am aware of virtual box/vmware for full virtualization but I am looking for something more lightweight (on my windows machine both come at a significant cost in battery life) closer to os virtualization level. Ideally, I would like something like windows 7/8 compatibility mode: the ability to run a program as if I were on 12.04. Does Ubuntu/Linux have such mechanism? What is the preferred way of running programs/scripts designed for an older version of Ubuntu?

• no ui or default configuration found?

  - by user51447

  I created a custom Ubuntu 11.10 amd64 desktop based distro using remastersys, but whenever I try to boot using the iso file in vmware, it shows this error : no ui or default configuration found I've tried changing the name of isolinux to syslinux but that didnt help me either! I also tried using unetbootin but it also doesnt boot, and tried every possible but to no avail. There is a similar question but it is about 10.10 and 32 bit, but that didnt solve my query and also as this is a custom distro, the solution could be different. I've also tried creating images using remastersys again and again but that wont help either. Please help me its very urgent!

• Missing Firefox app icon

  - by frozenkoi

  I'm using Ubuntu 11.04 (upgraded from LTS 10.04) and Firefox (version 11) doesn't show it's icon in the Window List panel, in the Firefox window top left corner (system menu) nor when using ALT+TAB to switch applications. I'm using unity 2D since I'm running ubuntu as a guest in a VMWare virtual machine (Host is windows 7) Instead of the Firefox icon I get what appears to be a generic icon that looks like an app window in the window list and a black rectangle with a curl in the bottom right corner in the ALT+TAB window. How do I fix this so that the proper Firefox icon gets displayed? EDIT: Depending on the icon set chosen in the Appearence settings window sometimes I get the icon, sometimes I don't. When using Ubuntu classic none of the icon sets provide the icon for Firefox.

• What companies do what I'm interested in? [closed]

  - by Alex

  I'm a systems guy. People change their concentrations to avoid taking operating systems, while I took it during my first semester after transferring. I'm taking compilers and networks now, and I think they're awesome. And yet there are so many job postings looking for people to do work in things like web development, and so few postings looking for people to work in kernel hacking or network engineering. What sorts of companies do these things? I'm currently awaiting a contract in the mail for an internship with VMWare, so I'm not out of a job for the summer. Still, I'd like to companies do these things.

• Monitor resolution can't be saved

  - by Iztok

  Today I installed Lubuntu 13.10 on Vmware Player (inside Windows). I change the Monitor setting (resolution) from default 800x600 to 1680x1050. It works. Beside Apply, I also press Save button. "Changes are saved" appears. But - after restart, the resolution is again in 800x600. I also opened /etc/xdg/lxsession/Lubuntu/autostart and add (it was empty before) one line: @xrandr --mode 1680x1050 After restart the default resolution is back again. Any idea?

• How to Avoid Maven builds stall on ssh host authenticity problem?

  - by Peter Kahn

  What's the right way to keep ssh host authenticity from being a problem for maven and hudsno builds? I have hudson building my maven project on a VM. When the ESX server with my VMs on it is taxed some of my jobs will stall out stuck in a loop of ssh host authenticity problems. The hosts were in the known hosts file, but during these times the clocks on the slave VMs have drifted far from those of my maven repo. [INFO] Retrieving previous build number from snapshots The authenticity of host 'maven.mycorp.com' can't be established. DSA key fingerprint is 6d:....83. Are you sure you want to continue connecting? (yes/no): The authenticity of host 'maven.mycorp.com' can't be established. Is there something other than disabling host checking (CheckHostIP no)?

• 2008 Datacenter Word Automation issue

  - by Brad

  We have an application that uses word automation. It works fine under Windows XP, but does not work on our Windows Server 2008 64-bit virtual machine running on VMware ESX unless it is running as the domain administrator. Under any other account (including a local admin), Word starts, uses a lot of CPU for 40 seconds when opening a document, and then just hangs. Our application does not access anything not on the local machine, and this machine is not being used for anything else (not a domain controller, etc). I know others have posted similar issues, with the solution of creating a Desktop folder somewhere under the windows directory. We did this, and it did not solve the problem (Word did not get as far as it did before we did this though). Please don't turn this into a thread about why I am trying to do this, whether I should do this, or whether I need to. For argument sake, I don't need to do this, but understanding what privilege a local admin does not have that is needed to do this is a legitimate concern.
