• Disable the network interface on a virtual machine

  Hello all-

  Is there a way to disable the network interface on the network adapter in the virtual machine?  We have a group of applications who want to simulate a network in collaboration with MSCS failure - I don't necessarily agree with the fact that this type of test, but try to determine if this is possible from the functional point of view.

  Our ESX host have networks of virtual machine set up off the coast of 4 port nic mezzanine card, and I don't want to touch the VM network vswitch as any part of this test.

  Thanks for any help you can provide-

  Is there a way to disable the network interface on the network adapter in the virtual machine?

  Yes, in the virtual machine settings, for each NIC assigned to the virtual machine you will find a checkbox 'connected '. Unchecking it's like pulling the network cable.

• Configuration host network interface problem

  Hello

  I use vmware player on Windows 7 Pro.

  After the upgrade to vmware server. I am not able to use the guest only network interface.

  In the configuration interface tcp/ip v4 network, the IP address is 192.168.38.1, but if I run ipconfig, IP assigned to vmnet 1 is 169.254.x.x (invalid IP)

  Anyone has an idea on how to solve it?

  Thank you!

  After the upgrade to vmware server

  Just an info, Windows 7 is not a host for VMware Server operating system.

  I am not able to use the guest only network interface. In the configuration interface tcp/ip v4 network, the IP address is 192.168.38.1, but if I run ipconfig, IP assigned to vmnet 1 is 169.254.x.x (invalid IP)

  Unfortunately starting with VMware Player 3, without a valid reason, I've never seen explained, VMware has stopped installing the virtual network Editor.  What I would try to solve the problem is to install manually and then use the restore default in the virtual network Editor to try to fix any problem with network cards virtual VMware.

  ==========

  To install the missing virtual network Editor, the command prompt:

  VMware-player-*.exe -e c:\vmptmp
  

  Then in the c:\vmptmp folder find the file c:\vmptmp\network.cab and extract (double-click on the .cab file) vmnetcfg.exe (virtual network editor) file in the working directory of VMware Player usually 'C:\Program VMware Player' or ' C:\Program Files (x 86) \VMware\VMware Player.  You can create a shortcut and place it with the shortcut of VMware Player, if you want to access it more easily.  Note: there are some for all the files to be extracted to then access the network.cab file.

• Network problem between the machines Win XP and Win 7

  I have 2 machines, a desktop and a laptop.  The office is currently running Windows 7 Pro (installed on 2010-01-01) and the laptop is running Win XP Pro.

  The desktop (Win 7) can see the laptop (XP) on the network and can access the shared folders.

  However, the reverse is not true.  The laptop can detect the office as a computer on the network.  I can double click the icon and see the files of office that are shared.  But when I try to access the content of the files, I get a message that says I don't have permissions and contact the system administrator.

  I also have a problem with the shared printer (connected to desktop Win 7).  Before the upgrade both machines can print, after the upgrade, the laptop (Win XP) stopped printing.  I installed the XP drivers for the printer (using the functionality of additional drivers) on Win 7, deleted the printer on the XP computer connection and he still added.  The XP machine was able to find the printer on the network, but when I try to print, I get an arror message saying that "(l'imprimante peut être désactivé, pas branché ou les pilotes ne sont pas installés)."

  I think that the two problems are related, but I can't understand where is the problem.  Print and file sharing is 'on' on both computers, the firewall is configured to allow printing the file and shares, folders are set to 'share', with "everyone" under permissions and both machines have the same network name.

  Any ideas? Am I missing something?  Is it possible to reset all default values so I can set up the network again from scratch?

  Thanks in advance a lot.

  Probably, you have a misconfigured firewall and/or do not have matching accounts/passwords user on both machines.
  Here are the steps of general network troubleshooting. Just cannot apply to your situation, so just take the bits that are. It may seem daunting, but if you follow the steps in the links and suggestions below calmly and consistently, you will have no difficulty to implement your sharing.

  Problems sharing files between computers on a network are usually caused by 1) a misconfigured firewall or a firewall neglected (including a dynamic firewall in a virtual private network); or (2) inadvertently run two firewalls such as the firewall of Windows and a third-party firewall. and/or (3) do not have accounts to the same users and passwords on all computers in the workgroup. (4) tries to create actions where the operating system does not.

  In Windows 7, go to control panel > everything in Control Panel > network and sharing Center. Click on "change the advanced sharing settings. You don't want to use the residential group unless you have all Windows 7 machines. If you do and you want to use the homegroup, see Windows 7 Help & Support. Otherwise, in sharing advanced:

  Discovery of plug in the network
  Open the files and printers sharing
  Turn on the sharing section Public folder sharing
  Plug the password protected sharing

  A. configure the firewall on all machines to allow traffic to local area network (LAN) as being approved. With the Windows Firewall, turning on window file sharing and printer as the above will take care of that for you. If you are not running a third-party firewall or you have an antivirus/security with its own firewall component program, then you're fine.  With a third-party firewall, I usually set up the allocation of LAN with an IP address range. E.g. would be 192.168.1.0 - 192.168.1.254. Obviously you would substitute your correct subnet. Refer to the safety of any third party program or the user forums for how to correctly configure its firewall. Do not run more than one firewall. DON'T STOP FIREWALLS; CONFIGURE THEM CORRECTLY.

  (B) to facilitate the Organization, put all computers in the same workgroup. This is done from the System applet in Control Panel, the computer name tab.

  C. create the counterpart of the user accounts and passwords on all machines. You do not need to be logged into the same account on all machines and assigned to each user account passwords can be different; accounts/passwords just need to exist and to match on all machines. DO NOT NEGLECT TO CREATE PASSWORDS, EVEN IF ONLY OF SIMPLE. If you want a machine to boot directly to the desktop (a particular user account) for convenience, you can do this:

  Start > Search box > type: netplwiz [Enter]
  Click continue (or provide an administrator password) when you are prompted by UAC

  Uncheck "users must enter a user name and password to use this computer". Select a user account to connect automatically by clicking on the account you want to highlight and press OK. Enter the password for this user account (when it exists) when you are prompted. Leave blank if there is no password (null).

  XP - set up Windows to automatically connect (MVP Ramesh) - http://windowsxp.mvps.org/Autologon.htm

  D. Si one or more of the computers on your network are XP Pro or Media Center, turn off Simple file sharing (Folder Options > view tab).

  E. create share as you wish. In Windows 7 I usually share the Desktop of the user and the Public directory.

  F. you have the job of file sharing (and tested by exchanging a file between machines), if you want to share a printer connected locally to one of your computers, share of this machine. Then go to the printer mftr Web site. and download the latest drivers for the correct system. Install them on the target machines. The printer must be collected during the installation procedure. If this isn't the case, install the drivers and then use the Add Printer Wizard. In some cases, printers must be installed as local printers, but it is outside this response.

• Bind Virtual Network Interfaces to the physical Interfaces

  Good day to all.

  My situation is as such:
  

  I have a virtual machine running Red Hat Enterprise Linux as guest OS and my host machine is a laptop running Windows 8.1. Each operating system has two network interface cards. I want to place the virtual machine on the line between a router that would be on the left (side Intranet) firewall followed by Internet on the right (side of the internet). I hope there is an option that would allow me to effectively "bind" one of each virtual NETWORK adapter to each physical NETWORK adapter, so that when I place the machine host on the network line, it would be like the VM would be online also. So, basically I want to accomplish what is highlighted in RED in my small figure above.

  The full rectangle is the guest OS with its two network cards on each side, and the incomplete rectangle is the host device with its own two network cards on each side. I hope that someone could point me in the right direction, it would be greatly appreciated.

  VMware Player, "Configure the adapter" parameters are indeed not unique for each virtual interface. You use VMware Workstation to meet your requirement. For workstation, you can create two VMnets and link your two adapters to them, then connect your two cards in the comments to the VMnet respectively

• VCo workflow to clone a virtual machine of centos. Network interface problem

  Hello

  I use vco workflows to clone a virtual machine of vcenter. The virtual machine is running centos 6.0. When cloning is complete. I see the network eth0 and eth1 interfaces set correctly the static gateway ip and address information I provided. I deleted the 70 - persistent - net .rules on the basic vm form which I clone. So, I get the correct interface names. But when vm powers on and I run "ifconfig eth0" I don't see the IP address of this interface has all the details.  same for the other interface also.

  But if I do a system restart network without changes to networking and then do an ifconfig I see the IP with the previous information.   I don't know why the service network restart is necessary so that he can recognize the ip address.

  Any ideas what I could do wrong. or to avoid this manual step of the execution of the service network restart command on the creation of the vm.

  Thank you

  Kiran

  Yes I'm restarting after after the application of customization.

  Has been able to solve the problem... In CentOS, the network service does not work by default. This is why it does not have network interfaces at startup. So now the machine instant, I started the network services and stop the Network Manager service

  using chkconfig network on

  chkconfig NetworkManager off

  and then cloned from this virtual machine... and apply the customization settings. during the start now it shows the interfaces properly without needing a service restart

• A duplicate name exists on the network

  Hello

  We are trying to install a 4.6 view environment and am getting an error on my VMs that a duplicate name exists on the network. The pool does not composer and is automated with assignment of the user of floating. I created a template which is Windows XP and on our field. Research on virtual machines that there where to create the pool, they each kept the model name VM's DNS name is following my pattern of naming. Is it possible to have virtual machine created by the pool GET a new name?

  Thank you

  You must use sysprep/quickprep to rename the guest operating system: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=2003797

  I think that you can only use quickprep with linked clones, so you need to use sysprep:

  1. download Microsoft sysprep (http://support.microsoft.com/kb/838080)

  2. you will need to prepare your sysprep answer file (it is a good guide: http://capitalhead.com/articles/force-sysprep-to-prompt-for-a-computer-name-during-mini-setup-in-windows-xp.aspx)

  3. If you are using the guide above and you let the ComputerName = * in place, it will automatically generate a new name for the computer for you.  If you remove the * you will need to enter a computer name whenever a new virtual machine is created.  Not exactly ideal because it is supposed to be automatic, but at least you would get a control.

  4. install the deployment tools XP on your server vCenter (C:\Documents and Settings\All Users\Application Data\VMware\VMware VirtualCenter\sysprep\xp)

  5 load your Sysprep.inf in your 'customization specifications' within the VI client.

  This gives you a name generated randomly for each virtual computer.  Unfortunately, I have not been able to find a way to make this name match the pattern specified in the pool.  I gave up at the end and switched to linked Clones as it makes the whole process a million times easier

  Hope this helps

• How to configure the private network interface between two VMS os invited using red hat linux

  Hello:

  I'm trying to set up a Real Application Cluster on my home office so that I can install Oracle 11 g RAC which is a facility where you have two servers accessing the same shared of storage (chipboard).

  In addition they will have a network interface private and a public network interface, so it will be for public interface eth0 and eth1 for interconnection of private networks.

  I read that I can set up using VMWare server, create Virtual Machines and install the operating system invited to them.

  I intend to install Red Hat Linux guest OS.

  My question is basically, how can I do for the establishment of the private network eth1, will be the guest OS to automatically install the sense (do I need to have 2 NIC cards for this), or where and how can this be configured?

  Also, how these two speeches of Virtual Machines to another on the private interconnect?

  And is it possible to use DHCP or do I need to add the IP addresses manually?

  Very grateful for your contribution to this topic, thank you.

  Kind regards

  Sam

  You can have network private without assigning a NIC cards (adapt).

  Hope this helps

• Change the network interface of the CLI on work/Linux Workstation 6.5?

  Greetings. vmrun seems to be able to do a lot of things on a virtual machine, but one of them is not to change the parameters of the network interface. Am I missing something? Is there a different CLI that allows me to do this?

  writeVariable and readVariable vmrun can be used to edit the VMX settings. Use the runtimeConfig parameter, and then name value pair. Not kept in the VMX file, but replaces the values stored there. Not to a Linux machine and could not test but should work if the value is stored in VMX.

• Director of the laboratory, adding new network interface

  Hello. I have a certain virtual machines in a workspace of LM and I would like to add another network interface. I have undeplyed the machine and it gives me the ability to add a new interface, however the interface I just added does not appear. How can I add this interface to a virtual machine that has already been added to a workspace?

  Looks like what you're trying to do is simply add a NETWORK adapter to a virtual computer in a configuration. It is fairly common and is detailed beginning on page 49 here http://www.vmware.com/pdf/lm30_users_guide.pdf. Let me know if it helps.

• Reoprts itdrep server already exists in the network

  Hello
  
  I have two AIX machines with different host names and server application independent of 10 gr 2 installed on both machines. I created a new report server with the name "ITDREP" on both machines (same name on both machines).
  Now when I try from the report server on the Computer1 it starts but after that if I try to start the report server on computer2 it fails with the error "Reoprts itdrep server already exists in the network.
  
  If I want to have a server of reoprt with the same name on both machines, what should I do?
  
  
  Concerning
  Ankit

  As you can see, the port = "14021' for the multicast network.
  If you specify on the second server port = "14022" then you can use the same name reportserver on both servers.
  Only downside is that you can send requests to report from the first server (to the help of run_report_object rwservlet, rwclient or forms) to the reportsserver on the second, but this isn't a problem if you have set up 2 servers identical for purposes of distribution of the load or high availability.

• TCP on PC server with the network interface has 2

  If I need to create a TCP on PC server with the network interface has 2 with a different IP address, for example 192... and 172... and the IP address of the client side is 192..., is there something I need to take care.

  Any suggestion, thank you.

  No, by default the server listens on all interfaces.

• duplicate name exists on the network: can spy on me

  I get this error message on an existing when duplicate name that I start.
  I read the patches for this, but what I'm wondering is...
  Assuming that the name "duplicate" is another computer, we are related in any way other than
  by name and network? I want to know if Name2 (the other) is aware of name1 (me) regarding
  like keystrokes, passwords, navigation, etc. ? What is the possibility exists for a name
  'spy' on the other? -I'm on a wireless home network.
  Because the error messages began, an oddity came with them... many times I have to
  Click a button a second time, then wait for 1-2 seconds, whereas before, a simple left click
  has brought an immediate response. Are us bogged down each other?

  Let us know if the issue of the double name reappears; It should not.

  I suspect that your mouse is having mechanical problems. Are you using the left button of the mouse much (for example, in games)?  Or there may be a foreign substance (dirt) in the switch.

  If you have another mouse, you can try for a while to see if the problem persists with another mouse.  You can also go in Control Panel > mouse and (temporarily) the right switch and buttons to the left of the mouse - but this is not something you want to probably keep for any significant amount of time and if the problem occurs only intermittently, you may not be able to definitively determine that it does not occur when you use the right button to the usual left button functions.

• Windows system error: a duplicate name exists on the network.

  I get an error message from windows at initial startup. The message is "Windows system error: a duplciate name exists on the network." How can I fix this?

  What version of Windows, including the service pack is installed?

  After the error, can you use the computer to access the Internet?

  You have a home network (i.e. more than one computer sharing an Internet connection) or this error pops up on a computer used in a business/company/Office?

  Assuming that there is a situation of home, what has changed recently in what concerns other devices (computer, printers, game boxes, etc.) added to the mix?

  How this computer is connected to the Internet?

  Make a right click my computer and select Properties.  Then click on the "Computer name" tab  The 'full name' should not be the same as the name of "workgroup".

  The error is a complaint that another device on any network to which your computer is connected to has the same name that the 'full name' shown in system properties (I assume that it is also possible that the error reports that there are two devices on the network with the same name even if none of these devices your computer).

  Although there are utilities that scan your network and to report the names of connected devices, they are somewhat nonsimple to use and may not work on a computer that will expose the error that report you.

  If your computer is on a home network, share an Internet connection using a router, you can manually check all other devices.  You don't maybe not easily able to determine the 'computer name' no computer network devices, but it is highly unlikely that such a device, for example, a network printer, would have the same name as your computer.

  Just to be sure there isn't something special going, disconnect your computer from your network (or your Internet connection) and then it reboot.  The duplicate name error should NOT appear if the computer is not connected to a network.
