• How to route public static IP to a virtual machine on a vmware ESXi host?

  - by Kevin Southworth

  I have 5 static IPs from my ISP (Comcast) and I have a physical machine with VMware ESXi 4.0 on it that is hosting multiple virtual machines. Right now I am just using the default vmware virtual network (vswitch0) with DHCP from the Comcast IP Gateway Router and everything is working fine. Each virtual machine can access the internet, etc. One of my virtual machines is a webserver (Windows Server 2008) and I want to assign it to 1 of my 5 static IPs so it's accessible from the public internet, while leaving the other VMs on the internal LAN still using DHCP. If I just plug my laptop directly into the Comcast IP Gateway (it has 4 ports on the back) and assign my laptop a Static IP using the windows networking dialogs, then I can hit my laptop from the public internet and it works great. However, if I try to do the same steps to set a static IP config on my Windows Server 2008 VM, it does not work. The VM cannot access the internet (open Firefox and try to visit google.com), and I cannnot see the VM from the public internet either. I'm assuming I'm missing something in the ESXi config somewhere, but I'm pretty new to ESXi and I'm not sure how to configure it to work this way.

• Is there an application that converts a PC into a video game kiosk/arcade machine?

  - by Rahil627

  Sorry to make the question so vague. What I ultimately want is software that allows people to play independent video games on a PC and not have to worry about maintaining it. Imagine a game that was made in a few hours that does not have a restart button and crashes often. It should be able to handle these kinds of things and do more! The software should: allow the game to be restarted manually handle game crashes (likely by restarting the game) restrict the user from doing anything crazy later... offer a UI to select the game from a list handle pre-configured key bindings cross-platform (start with windows) I just want to know if this exists already before I start creating one. As of now AutoHotKey is being used to do this sloppily. If such software does not exist then perhaps someone could recommend a general open source Kiosk software? Open Kiosk? I'll take anything. (I also could not find a related tag. Not even sure if this question should be here rather than stackoverflow)

• How do I control remote Windows 7 machine? VNC/RDP/?

  - by artfulrobot

  I have a Windows 7 laptop that's going out and about and I'd like to be able to admin' it from my Ubuntu (precise) desktop. While the laptop is in my office I can use Gnome's "Remote Desktop Viewer" (Vinagre) to connect via RDP. However, when it's in the office I don't really need RDP of course! And when it's out of the office I cannot control the routers/firewalls along the way, so I won't know the IP and cannot set up port forwards. I'm looking for a Ubuntu compatible way to achieve this. Nb. I can set up port forwards at the my office end, so a service on the laptop could try a "backwards" connection to my client.

• Windows 7 can't see wireless printer

  - by Chance Robertson

  I have a P1102W printer from HP. I have a Windows 7 machine. I have a MacBook Pro. I setup the printer following the instructions from the Windows 7 machine. I am able to print from the Mac but not the Windows 7 machine. And to add, I am not able to print from any Windows 7 machines. The MacBook Pro address is 198.168.2.115, the Windows machine is 192.168.2.117, and the printer in 192.168.2.140. I can ping the printer from the Mac. I can ping the Windows 7 machine from the mac. I can ping the mac from the windows 7 machine. When I try to ping the printer from the Windows 7 machine I get destination unreachable. I can browse to the printer IP address from the mac and not the Windows 7. I have turned off the firewall on the Windows 7 machine and turned on network sharing. Is there something else I am missing. I can connect the printer with a USB cable to the Windows machine and print. I can not get the Windows machine to see the printer even though they are on the same network.

• Chrome OS pourrait passer du Cloud au client léger et les applications hébergées sur une machine dis

  Mise à jour du 10/06/10 Chrome OS pourrait passer du Cloud au client léger Les applications hébergées pourront l'être sur un ordinateur distant : les professionnels en ligne de mire ? C'est sur un groupe de discussion de Google que Gary Kačmarčík, un responsable de développement du projet Chromium OS, a laissé entendre que Chrome OS devrait s'enrichir d'une fonctionnalité assez proche de celle d'un client léger. Pour mémoire, Chrome OS était jusqu'ici orienté exclusivement Cloud. Autrement dit, il était destiné à faire tourner des applications dans le navigateurs (de type Google Docs ou, pourquoi pas, les

• Accessing SQL with the PC name not the IP

  - by Cornelius

  I'm trying to connect to a SQL instance (default instance) on a machine. When using the IP of the machine it connects to the machine. Using the name of the machine on that machine you are able to establish a connection to the SQL instance but using the machine name on another PC the connection cannot be established. And gives the error A network-related or instance-specific error occurred while establishing a connection to SQL Server. ... (Microsoft Server, Error: 10060) The machine that I am trying to establish the connection from can ping the machine with the SQL instance both on the IP and on the name. Why would this be and how can I fix it? Edit: pinging the name does resolve the correct IP. Pinging the FQDN also works correctly.

• Introduction à CRaSH, un shell pour superviser une machine virtuelle Java, application à la visualisation d'un cache, par Damien Rieu

  Bonjour, Vous trouverez un article sur CRaSH à cette adresse : http://damienrieu.developpez.com/art...hcache_spring/ CRaSH permet de se connecter à une JVM en mode Shell puis d'exécuter des commandes directement sur cette JVM. Ainsi, nous allons accéder à un certain nombre de commandes prédéfinies (exemple la commande thread, jdbc, java?). Une des grandes forces de CRaSH est que l'on peut aussi définir ses propres commandes Shell par programmation (Syntaxe Java ou Groovy). Il est alors possible de réaliser des commandes spécifiques à nos besoins ! Dans cette article, nous allons présenter CRaSH grâce à un cas pratique. Pour cela, nous allons réaliser une comman...

• CUPS printer on Vritual Machine can be access via CUPS admin, but not by XP?

  - by SJaguar13

  I have a Zebra label printer connected to a Linux Mint virtual machine. It was set up with CUPS and a Windows XP computer can then print to it via http://192.168.1.76:632/printers/labelprinter. That was all fine and dandy I then hooked up a Fargo Pro L PVC card printer to a Windows XP virtual machine. I had to disconnect the label printer as the server that hosted both virtual machines only has 1 parallel port. Now I plugged in the Zebra again, and it cannot print from the Windows XP computer anymore. If I go to the CUPS admin panel on the Windows XP computer, I can see it, everything looks fine, and I can send it a test page to print which works. If I try to print from Windows, I get an error that the printer is not found/cannot connect to the server. The only other thing that changed was the firewall on the router to allow remote desktop to another computer from outside the network, but all the firewall stuff was for external use. Nothing affected the IP address of the internal network. The Linux Mint VM also had a PDF pritner that was shared with CUPS. That printer is also down. I tried setting up a new CUPS installation on another VM, and when I go to share it with XP, I get the same error. I don't know what to try. It has access, it can get to the admin from that computer, it seems to be up and ready, but when Windows tries to connect, the printer isn't found even though 4 days ago everything was fine. Any ideas?

• the kvm's terminal works weirdly

  - by Lai Yu-Hsuan

  I connect to a remote machine from the local machine and use virsh console to enter the virtual machine. I don't know how to exactly depict how it works. Normally it works well, but when I run VIM: Then it can't be recovered unless I cut the connection up: It's very hard to work with a broken terminal. Any advice? My terminal works well on my local machine and the remote machine in which the virtual machine runs.

• System freeze after opening Wi-Fi menu can boot into the machine and use Internet in recovery mode

  - by Michael

  So right now sitting in front of my Alienware area 51 desktop. It has a Broadcom Netlink BCM 5784M gigabit ethernet PCI E card. Most of the time able to get through the login screen and to the main screen if I click on the wireless settings on the top right-hand corner the system immediately freezes the cursor does not move at all keyboards are unresponsive. I was doing some quick Google searching and I found a suggestion to boot into recovery mode I did this and did a apt-get Distribution update which ran successfully installed then I rebooted into the regular system same thing I'm pretty sure it's the network card because even if I don't click the settings if a network related dialog opens such as disconnection or connection the system again immediately freezes. I'm running Ubuntu 13.04 ** update 1 ** Just was able to use my system for a little bit however when I went into Firefox and hit the web it again froze so obviously a driver problem but I'm not sure how to get drivers for Broadcom which apparently according to the description on stack-overflow is terrible Any ideas? Sorry for lack of punctuation on an ipad.

• Instructions to setup primary and only domain controller

  - by Robert Koritnik

  Where could I get best step by step instructions (with some simple explanations) how to setup domain controller on Windows Server 2008 R2 Server Core? I don't know what do I need? Do I need DNS as well and AD and so on and so forth. I don't know enough about these things, but I need to set them up to prepare development environment. I would also like to know how to configure firewall on DC machine, to make it visible on other machines because I've setup DC somehow but I can't connect to it... This is my HW config: Linksys internet router with DHCP my dev machine is Windows 7 my DC machine is a VM in my dev machine my dev machine has a hw network adapter to linksys and a virtual network adapter to DC DC machine has two network adapters: one to linksys (to be internet connected so it can be updated etc.) and one to host (my dev Win7 machine) Edit My development machine should access domain controller and logon using domain credentials. Development machine would access internet directly via Linksys router. My domain controller machine would only serve authentication (and if I'm able to configure it right) should also have Active Directory Federation Services in a workable condition. I hope this is a bit more clear now. At least a small bit.

• Dual booting windows 8/ubuntu 12.04. Grub doesn't appear and machine never boot in ubuntu

  - by black sensei

  i got a new ACER predator AG3620-UR308 which came with windows 8, so i wanted to run ubuntu 12.04.2 on it as a dual booting. To be honest, i've been doing dual booting for a while now so, i did the right thing. the box came with 2TB HDD. so i made 4 partitions with a raw partition just after the windows installation partition I always do manual installation so even if ubuntu didn't detect windows 8, it was ok for me. So i created swap area and finished the installation etc....Grub was install on the only drive there which is sda. After reboot, grub doesn't even come up.So it always boot in windows 8. I did repeat the installation process twice and yield same result. which is weird because this method always works for me so far.Even the laptop am using to write this post is a dual booting windows 7/ mint nadia installed the same way. Is there anything new in windows 8 that i didn't make provision for? Before starting the installation, all i read about was that , windows 8 should be installed first and ubuntu after. I went ahead and disable secure boot from the BIOS and enabled CSM (don't even know what it means) according to Acer custhelp site .

• Windows based development environment: HyperV, VMWare, or VirtualBox on development machine?

  - by bleepzter

  I am a software engineer with a little bit of an informal "support" functionality... I am trying to figure out what is the best possible approach to employing virtualization technologies into our development process. Since the code we develop is server-centric, testing it often requires a VM with specific software requirements. I used to use VM Ware player (free version) to run my VM's until both of my laptops started exhibiting issues with corrupted windows 7 services and dying hard drives. All leads pointed to VMWare, which by the way seems to be a solid product if you pay for the Workstation edition ($300). On a side note, I have always been a fan of the Windows Server product line. I think it makes for one of the best development environments out there - it is highly scalable, highly reliable, and very efficient. So to be fair I replaced the drives of the laptops and installed Windows Server 2008R2, VS2010 Ultimate SP1, SQL Server 2008R2, TFS Server 2010 and all other tools and API's needed do do my work properly. So now I am stuck with a bunch of VMWare VMs. I don't want to repeat of what happened before, and I certainly don't want to bog down my machine with an inefficient hypervisor or services that are not needed. Futhermore the VMDK hard-disk format used by VMWare is not compatible with the VHD format of Hyper V. It is my understanding that converting from one format to the other can only happen by Microsoft System Center Virtual Machine which I have downloaded from MSDN and ready to install. I guess the question at this point is: Does SCVM run as another service in Windows? Is it a memory hog? What is a better virtualization technology - Hyper-V or Virtual Box in terms of efficiency ease of use and most importantly - memory footprint? (Keep in mind the development environment already has a ton of services running such as TFS Server, SQL Server, IIS, etc...) How would you advise to proceed at this point so that the VMs are still used in the test process? Thanks Martin

• How to rewrite a TCP MMOG server designed to run in a single machine, in a distributed way?

  - by Dokkat

  I have a MMOG server running on C++, using winsockets. My server won't support more than 200 players. I had the idea of redesigning it so it will use multiple servers instead of one, so, maybe, for example, each server could take care of a number of players, and, if it was too laggy, it could transfer the responsability of that player to other server. I'm not sure of how to program a consistent game logic like that, though. Are there techniques for this?

• Solutions for cheaply replacing poorly-supported onboard ATI card with discreet graphics on desktop machine?

  - by echo-flow

  I have put Ubuntu on my mum's desktop computer. Unfortunately, the open source radeon driver does not work well with the onboard ATI graphics, and ATI's proprietary driver no longer supports the hardware at all. In order to use the ATI proprietary driver with this hardware, it is necessary to use an older version of Xorg, which is now only available in versions of Ubuntu older than 8.10. Unfortunately, the open source radeon driver seems to be causing X to lock up intermittently when my mum uses Audacity. I'm willing to accept that some hardware is not well-supported on Ubuntu, and so, because this is a desktop computer with a couple of free PCI slots, I think a better solution might simply be to plug in a new graphics card that might have better driver support, and to disable the onboard ATI card in the BIOS. The requirements for this card are that it be inexpensive and have robust (preferably open source) driver support in Ubuntu 10.04. Heavy-duty graphics processing power is not a requirement. A second-hand card on Ebay would also be fine. Can anyone make some recommendations?

• Large scale file replication with an option to "unsubscribe" from a replicated file on a given machine

  - by Alexander Gladysh

  I have a 100+ GB files per day incoming on one machine. (File size is arbitrary and can be adjusted as needed.) I have several other machines that do some work on these files. I need to reliably deliver each incoming file to the worker machines. A worker machine should be able to free its HDD from a file once it is done working with it. It is preferable that a file would be uploaded to the worker only once and then processed in place, and then deleted, without copying somewhere else — to minimize already high HDD load. (Worker itself requires quite a bit of bandwidth.) Please advise a solution that is not based on Java. None of existing replication solutions that I've seen can do the "free HDD from the file once processed" stuff — but maybe I'm missing something... A preferable solution should work with files (from the POV of our business logic code), not require the business logic to connect to some queue or other. (Internally the solution may use whatever technology it needs to — except Java.)

• What are some advantages / disadvantages to working on a remote development machine?

  - by robertpateii

  At home I have a fast rig with my dev environment running in virtual box. that works great, but at work I have a so-so laptop that can barely push visual studio express, outlook, and a dozen chrome windows at the same time. So I can either ask for a dedicated desktop to do development on, or I can ask for a slice on an existing server from IT and remote into it. Setup-wise, the remote option is faster and cheaper. But I don't know its affect on production in the long term. I've done small amounts of work through a remote connection, but never extended development. Do you have experience with this? What are some of the ads/disads to it? Did it make you less productive?

• "Meet in the middle" with SSH

  - by stillinbeta

  I have an interesting question regarding SSH. I have a machine at school that I'd like to be able to access from elsewhere. It's behind a firewall/NAT, so I can't get at it directly. I have a leased web server that I can SSH into from anywhere. I was wondering if I could do some voodoo with port forwarding to get to my machine at school via the web server. I think this comes down to whether you can do SSH "backwards," which may or may not be possible. Basically: Machine A can access Machine B Machine C can also access Machine B How can Machine A access Machine C?
