IPSec on VMWare ESX 5.1 communication problems

Hello

We have 2 computer systems.  You running us VMWare ESX 5.1 and the other is running Ubuntu 14.04.  We have problems for IPSec to work between the two systems.  We cannot find any documentation or known issues with IPsec on VMWare ESX 5.1, so we're going to reach out to the community.

Here's what we did:

1. we configured Ubuntu and VMWare systems to use IPv6, we can ping each other using IPv6.

2. we configure IPSec on an Ubuntu operating system by following the instructions below:

https://help.Ubuntu.com/community/IPSecHowTo

3. we have followed the instructions below to configure IPsec on VMWare.

http://KB.VMware.com/selfservice/microsites/search.do?language=en_US & cmd = displayKC & externalId = 1021769

Here's the problem:

When 2 Ubuntu systems run IPsec, they are able to ping each other.  However, when allow us IPSec communications between VMWare and Ubuntu, the ping is suspended.

Here is the result of the configuration of command esxcli on VMWare:

UBUNTU. IPv6.ADDRESS-> Ubuntu IPv6 address

VMWARE. IPv6.ADDRESS-> address IPv6 from VMWARE

GoToDPSP UBUNTU. IPv6.ADDRESS/64 0 VMWARE. IPv6.ADDRESS/64 0 in ipsec transport GoToDPSA

Here's what we found:

After debugging the problem (using tcpdump), we found that the VMWare system sends the ESP packets, but never sends a package AH (required for IPSec authentication).  Even when the encryption protocol is null, the system of VMWare would always send ESP packets, but never once sent a package of AH.

Here is the resulting execution trace: Ubuntu - ping-> VMWare:

...

Summary:

There seems to be a problem with IPSec in VMWare ESX 5.1 on IPv6.

We noticed that the downloads section of the site support provided patches for VMWare ESx 4.x and earlier, but lack of patches for VMWare ESx 5.x.

Are there known issues in this area or available patches to fix this problem?  Your kind suggestions would be greatly appreciated.  Thank you.

Sorry for the late reply, but here the analysis of what is happening and why you are experiencing a problem.

The Encapsulating Security Payload (ESP) to IPsec protocol will encrypt a payload of the packet and can

Optionally authenticate the packages as well. You do not include orders allowing you to set the

Security Association (SA) and political security (PS), but the output in your post indicates that you

you want to encrypt the payloads both authenticate packets in mode of transport between the hosts.

I don't know why the Ubuntu IPsec HowTo examples using protocols AH and ESP to encrypt and

authenticate the packets. In our view, it is best done in a single step with ESP, ESXi only

offer the option of AH with IPsec. Of course, this requires configuring the ESXi server and your

The host with a configuration of IPsec compatible Ubuntu (or any other operating system).

To illustrate, suppose the ESXi server has the address 2001:db8:1 and the host of Ubuntu has the

address 2001:db8:2. We will use cbc-3des for encryption of the useful and hmac-sha2-256 load for integrity

authentication mode of transport - just like in your message.

On the ESXi host, the commands to do this might look like this (of course, you need to generate your)

own keys and not re-use those I did).

use the command setkey BSD-door, this is done by changing the system-wide

    The datstore view is fine. That you see only files hard.

    There is only one HARD drive attached to this virtual machine? Please also browse the data store on the SC and see if you can see one - file flat.vmdk. If the file is there, the disc should be fine.

    Please also check the vmx file to confirm if the path of the HARD drive is correct.

  • VMware ESX 5.1 storage problems provided - please help!

    I have a virtual machine on a 1 TB drive, I configured 750Go, however my vm was interrupted with an error - not enough space, I can't make instant etc..

    How is that possible? I'm not an expert vmware ;-)

    I gave this virtual machine 750 GB. Attached snapshots.

    How to fix pls?

    Why is that what it's showing size 1.4TB funded? I gave him 750 GB?

    Is it because I went for the provision of the 'thick '? Still should be 750?

    The output of the status of the disk space is caused by the virtual machine running on a snapshot. This snapshot has already passed to close 180 GB.

    What I would say is to backup the virtual computer (power off) and then remove the snapshot from the "Snapshot Manager". Due to the size of the snapshot, this could take a while, so please be patient.

  • VMWare ESX Server training

    Hello experts,
    I'm new to vitrualization.
    I installed vmware workastation v 7.0 and I also have VMWare ESX Server training Trainsignal dvd for training so here are my questions:

    Can I install VMware vSphere Hypervisor 3.5 on my VMWare Workstation 7.0 for training v?

    Is - this VMWare vSphere Hypervisor 3.5 product different from VMWare ESX Server 3.5?

    I'm you ask all these questions because I want to be sure I can complete a training with VMWare vSphere Hypervisor 3.5 suite drive of my Trainsignal VMWare ESX Server 3 and because I am not allowed to download the evaluation version on VMWare ESX Server 3 and because the VMWare customer service could not answer my simple question and quoted me to the community by them to get advice.

    Thanks in advance for your help and advice.

    Hi nasolsi,

    Can I install VMware vSphere Hypervisor 5 straight on my VMWare Workstation 7 training without affecting my HDD physical whole?

    Yes, it has nothing to do with your actual score and highlights form the part of space, he took from your partition to create the disk of the virtual machine. So basically it will eat the space in the physical partition but does nothing else like the formatting of the entire disk.


    and the performance on my PC?

    No, this will not affect your PC's performance as the workstation will run the pages of RAM and cycles on your physical PC hardware microprocessor.


    If permitted increase RAM by a value so that you do not encounter CMTF or any other problem. 2048MB is the minimum memory required to run ESXi.

  • Configuration of IPSec in VMWare ESXi can be applied to virtual machines running?

    Hello

    I have an operating system running inside VMWare ESXi 5.1.  Let's call is "MyLinux".  It is a modified version of Linux which does not support IPSec.  So I try to get VMWare to manipulate IPSec for MyLinux.

    I used esxcli orders to successfully create configurations for IPSec between VMWare itself and other systems.

    However, I wonder if I can use the same esxcli commands to configure IPSec between MyLinux and other systems?  In my tests, VMWare does not perform tunneling IPSec data between the running machines and other virtual systems.

    It is an illustration of the configuration I created for MyLinux in VMWare.  I also have a security policy that is not visible.

    When I captured a trace TCP ping between MyLinux and the external system, MyLinux never sent the IPSec packets. Everything was sent in the clear.  This suggests that VMWare does not apply the rule for MyLinux, but I would like to confirm.  Thank you.

    When you configure IPSec on ESXi, you sécuriserez the VMkernel traffic, not the virtual machine... If you want to protect the traffic of the virtual machine, you will need to enable IPSec on guest operating system.

    Hallo zusammen!

    I have several questions zu obigem Sachverhalt und hope, dass mir von Euch helped werden kann.

    Wir haben einen host ESX (VMware ESX 4.0.0) den wir via vSphere von einem Windows Server aus, verwalten. Auf dem ESX host wollen wir nun start, die first VM (ins Leben zu find) zu installieren. ES sollen OS installed werden (. ser on W2K3 / W2K8 STD (R2), company / business,...).

    Wir haben also license so: 'Windows Datacenter 2008 R2 64 bit 4 CPU. After we die erste VM installed haben, wanted sharp wir mit dem Lizenzkey der Datacenter license aktivieren. Unfortunately works weder der 'Product Key', noch der 'Virtual Key'.

    WO ist mein Denkfehler? Wie die of ich lizenzsiere auf einem host ESX VM procedures meiner Datacenter license Windows-VM?

    Bei einer Aktivierung eines W2K8 STD. servers add to the (ublicherweise) einen VLC (VolumeLizenzKey) der eine unlimitierte Aktivierung allows.

    Wenn nun keinen VLC As, so wende Dich an den suppliers der DatacenterLizenz oder direkt from MS. Mit den entsprechenden Lizenzpaieren und Kaufbelegen solltest VLC key bekommen die.

    Hello I am a student and write my thesis of license.

    The theme of my thesis is the 'comparison of VMWare ESX Server and Citrix XenServer'.

    After I installed XenServer on the material, I was able to simulate the material and got the possibility of

    OEM-Versions of Microsoft operating systems install VM on XenServer. With this feature can save our customers

    money, because they can use the Versions OEM of MS products provided by our care.

    Now my question! Is it possible to simulate the material on VMWare ESX Server and install the OEM Versions

    or are there other ways how I can install the OEM Versions on VMWare ESX Server?

    I've seen this kind of problem before as well and it's the media. Try to download eval software as an ISO and see if it works.

    I know say you it worked with xenserver then why not with esx - I can't answer this question I can only tell you want that I found worked.
