• Disable communication between the host and the virtual machine

  I have VM Server 2.0 and one of the virtual machines has the same name as the server and even if the virtual computer is connected to the host only network it generates the Windows error message: duplicate names exist on the network.

  is there a way to disable communication between the host and the virtual machines? I just need a virtual network that is isolated from my network complete and host also.

  Thank you.

  The GUI Server2 is not to choose the other unused vmnets.  Then edit your file VMX use a different vmnet of 0, 1 or 8.  (which are bridged, host-only and NAT)

  Thus, for example, if your VMX has a line that says:

  Ethernet0.VNET = "VMNet0.

  change to:

  Ethernet0.VNET = "VMNet2.

  (This assumes that you have not used the network Editor to fill the vmnet2 either).

• vCenter 5.1 - network problem between the host computers

  vCenter 5.1

  (2) the hosts running esxi 5.1

  I have VM in a single dvSwitch and dvPortGroup on two hosts - VM total 5.

  This is where it gets weird:

  -all VM on host1 can ping/browse all VM on host2

  -VM on host2 can ping/browse all * EXCEPT ONE * VM on host1.

  -All virtual machines can ping Bridge and beyond

  Otherwise said - VM1 on host 1 may VM3 and VM2 host2 ping, but VM3 and VM2 cannot ping VM1.

  No firewall or anything like that in the guests, because VM4 on host1 * CAN * ping VM1.

  Looks like an arp or vNetwork question.

  Thoughts, known problems?

  Found!

  I got 2 ports not tagged in the VLAN for switch problems.

  While everything went on-site in the configurations, hard links to the switch are the root cause.

  Thanks for your comments - he has led me on the way to finally discover the question.

• How to enable the communication between the host and the virtual from Windows 7 computer

  Host: Mac OS X 10.6

  Setting of networking: NAT (also connected to the VPN work)

  VM: Windows 7

  I use my mac for my development. I have an application running with the Web Server server. I also use the hosts so that I can map the URLS of different web site with the same ip address.

  For example:

  On my Mac in/etc/hosts

  127.0.0.1 www.testsite1.com www.testsite2.com

  On my virtual from Windows machine in the hosts file

  987.78.125.125 www.testsite1.com www.testsite2.com

  When I'm at the office and using bridged connections, it works very well. However, I prefer to use NAT all the time.

  Is this possible?

  
  Thank you!

  I actually already answer your question but now I know the details, and by the way you have explained so much better the second time!

  When not connected to the VPN on the host computer and the guest knows the IP address of the Web server on the host (an appropriate entry in the guest hosts) then it should work but when connected to the VPN, if you are administrator does its job well, that you should not be able to connect the host to the guest for the reason mentioned previously...  Authenticated/no unapproved system (guest) cannot access an authenticated / trust system (host), while the VPN on the host computer is set up to your corporate network.

• Network problem between the host computers

  I am in the process of upgrading all my ESXi hosts and I came across a strange problem that I didn't know.  I have 2 guests (two ESXi) and I have a few VM I can't ping when I migrate from one to the other.  This virtual switch has 30 virtual machines running on it and I have two that will not work on a single host.  I run a constant ping and as soon as I migrate to a host I lose my connection ping.  All other virtual machines are still running and very well.  I'm quite puzzled why.  Someone has an idea?  Thank you

  Host2 - ESXi - the virtual machine in question work on this one

  Host4 - ESXi - the virtual machine in question do not work on the work of this one, but all the other fine vm.

  Remove the network adapters on the operating system. UN install VMware tools. Remove the network card settings of the virtual machine. Restart the operating system. Reinstall the VMware tools. Add network adapters on the virtual machine. New analysis of the material changes. Re add parameters, etc.

• No communication between the Bluetooth SD - BT2 and PocketPC SD card

  I use an SD - BT2 (PA3271U) card in a Microsoft Pocket PC (also referred to as 'Microsoft PocketPC 2003') 4.20.00. I use the latest driver Toshiba 5.01 C and the card is recognized by the Pocket PC (Medion MD 95450 / MDPPC 150). I can connect to my mobile phone and GPRS connection is accumulation with no problems.

  But later at this point in time, the connection is established but dead... no connection to anyone. It seems that the communication between the Pocket PC and the card SD - BT2 is broken on the software side.

  Anyone have an idea (or a working driver) for this problem?

  Thanks in advance

  Karl

  Hello

  Have you tried to reinstall the drivers or software for SD - BT2?
  In my opinion, you should check this option.
  Also, I found a brand new version for PDA Bluetooth Stack (Bluetooth software and drivers).

• LabView RT versionconflict between the host and target

  Hello everyone,

  for my diploma, I work with a compact system in rio (cRIO-9074) with two I/O-modules. After some research, I created a small project which includes an fpga - and a host vi. I wanted to test my project, so I've compiled the fpga vi and you want to run the host-vi. But then I got an error that said that the versions of the software LabView real-time between the host PC and target (is the cRIO-controller meant?) are different.

  As a solution, I was told to check versions and reinstall the software Real Time using MAX. Now my problem is that I don't know where I can check the version and/or how I can solve the problem to get the project running.

  I added the errorwindow (in German) as an attachment.

  I hope you can help me.

  Better subject.

  MAX is measurement and Automation explore National Instruments.  Open, then expand "remote systems".  You should see your cRIO system.  Expand and you will see 'software' in the list.  Right-click on it and choose to install the software.  That will open a window that will allow you to select what software and what version to install on the cRIO.  Install the version of LabVIEW that matches the one that you use for development.

• Encrypted L3 Communications between the TOWER and WLC?

  Hi all

  I work with a client who wants to put the towers away to their WLC (a 4402). The problem is that communications between the TOWER and WLC must be secured, even through their private Wan! I have a few questions that result, if someone is able to help you;

  1. I can't know if and what method of encryption is (is it AES etc.?) used on connections between towers and the WLC and what are the steps?
     1. The terminology can be a problem here, it's not a wireless mesh, just classic LAP for WLC
  2. EXTENSIVE customer network is already encrypted (IPSec VPN via VPLS) in parts - what is the consequence of execution of AP<-->WLC with end to end (if possible) on a network encryption EXTENDED with IPSec, i.e. double encryption?

  Strange but true - pointers will be greatly appreciated... Phil.C

  With a controller of the 4400 series, the control traffic between the AP and the regulator is already encrypted AES.  The user traffic is not encrypted.  If you use a 5508 controller all traffic between the AP and the controller is encrypted AES.

  For what is running the traffic through a VPN, it should work.  The issue I see with this is with the MTU in general.  The controller will drop all packets with a payload of less than 32bytes data.  According to the MTU over the VPN I've seen packets getting fragmented and it is a question.  If you use one of the versions CAPWAP (5.2 or newer) discovery dynamic MTU is part of the Protocol and this MTU problem does not really exist.

• How to configure the network between the host (Windows 8) and Guest (Linux)

  Hello

  I am trying to configure network between the host (Windows 8) and Guest (Linux). Guest on VMware Workstation 8.

  Using this network, I want to configure putty so that I can access comments linux to a PuTTY that is installed on the host (Windows 8).

  Thank you.

  Abdul

  To obtain external access to comments (access the guest from the host), you must configure the IP static within the guest (Linux) as below and restart the network (service network restart)

  eth0 is a dynamic IP (DHCP) to get wireless internet access

  eth1 is a static IP address

  

  

• Workstation 9 - slow network performance between the host and guest

  I am running windows 8 on the host and installed by 9 trial. Then installed windows 8.1 as a comment system.

  I'm a slow, very slow network between the two.

  If I send files to and from the computer with another guest, transfers are normal, but if I try the same files between the host and the guest, they are really slow.

  I use a bridge connection.

  I read elseware to disable the following on the guest card:

  Large Send Offload v2 (IPv4)

  Large Send Offload v2 (IPv6)

  But that did not help.

  Thoughts?

  Maybe then try Hyper-v, it help you better.

• Sharing data between the host computer stores in different groups.

  I read in several places that sharing of data warehouses between the host in different groups is possible, but I don't get the warm and fuzzies when the hosts are different versions.

  vCenter is 4.1

  Group Alpha is 4.0 vmfs 3.33

  Bravo of cluster is 4.1 vmfs 3.46

  My goal is to move the virtual machines that meet the specific criteria of group Alpha for Cluster Bravo then the availability of flowing freely between clusters.

  The only concern I have is when adding Cluster Bravo to the same host of 3PAR alpha value of Cluster sharing all the data store, Cluster Bravo will try to reformat to vmfs 3.46 break Cluster Alpha to see the virtual machines stored in the warehouses of shared data?  I don't want to present the old warehouses of data to the new cluster only break from old cluster.

  Hello vmsjsn

  ESX/ESXi 4.X supports all versions of VMFS file system.

  Using your example of Alpha and Bravo. Kudos to will write more Alpha. you will be able to cross all hosts on the shared storage.

• Difference between the hosts and virtual machines

  Happy new year!

  I guess that's a stupid question, but I don't know the answer to it.

  I created pools from VM. Some jobs in the pool are hosts and some virtual machines. What is the difference between the hosts and virtual machines. I thought I could only create virtual machines, but I guess I could create hosts as well. -What happened?

  Thanks for your help.

  where does say desktops are hosts?  A host is usually referring to an ESXi server.  A virtual machine is just the guest OS running on the host computer.  A pool is a group of VMs that can extend over several hosts.

• Is it posible to allow access between the host and virtal machine without wired network?

  I want to use my laptop to show him that I did in the virtual work to other people at my home.

  However, the laptop is ofen not allowed access to the network in their office.

  Is it posible to allow access between the host and virtal machine without wired network?

  My virtual machine is filled to the physical network adapter and use the static IP address.

  Brad

  Setting of the virtual machine: filled

  Change that to each host only (what Continuum called VMnet1) or NAT (VMnet8).  Both use a separate virtual NETWORK card to connect the physical computer virtual host, independent of any NETWORK adapter on the host.

  ... Since the machine host (win7) could not get IP, ping fail to VM (192.168.1.5)...

  Because the connection between the guest and the host is through a separate NETWORK card, you must use the 'other' IP address.  Access a prompt on the host computer and type IPCONFIG to view the IP address of VMnet1 and VMnet8 NIC.  Then use this IP address instead of 192.168.1.5.

  And when you have changed the network management modes (i.e. of bridged to host-only), Windows does not automatically renew its IP address.  The virtual NETWORK card uses a different subnet if you need to renew your DHCP lease or change your static IP address to work with the new subnet.
