PowerCLI issue on CentOS 7 Linux

  • 1.  PowerCLI issue on CentOS 7 Linux

    Posted Nov 05, 2018 10:07 AM

    Hi everyone,

    I wrote a simple script that gathers informations from vCenter servers and I'm trying to making a port to Linux.

    I'm using CentOS 7, got PowerShell 6.1 Core installed and PowerCLI 11 directly from the online repository.

    When I try to connect to the vCenter server version 6.7 I get this error:

    Connect-VIServer : No such device or address

    The same thing happens with version 6.5.

    I get no problems at all if I connect directly to hypervisors.

    Do anyone had such kind of issue with PowerCLI on Linux?

    Many thanks in advance!

    Thanks for the response daphnissov

    I have followed below steps and please let me know if i missed out anything.

    1. Downloaded this rpm ` powershell-6.1.1-1.rhel.7.x86_64.rpm` from here Release v6.1.1 Release of PowerShell Core · PowerShell/PowerShell · GitHub

    2. On the CentOS host machine installed this rpm using `rpm -ivh powershell-6.1.1-1.rhel.7.x86_64.rpm` along with `yum install libicu` as powershell depends on this package.

    3.Installed PowerShell version is 6.1.1


    [root@m**-vm1 tmp]# pwsh

    PowerShell 6.1.1

    Copyright (c) Microsoft Corporation. All rights reserved.


    Type 'help' to get help.

    PS /tmp>


    4.  Then installed `VMware.PowerCLI ` module using this command `Install-Module -Name VMware.PowerCLI`. The version details shown below.  VMware.PowerCLI                 PSGallery        This Windows PowerShell module contains VMware.PowerCLI

    5. suppressed the certification error using this command `Set-PowerCLIConfiguration -InvalidCertificateAction ignore`

    6. Tried to connect the vSphere using `Connect-VIServer -Server 10.xx.xxx.xx -User mu****@vsphere.local -Password W*****! `  then i noticed the below error.

    Connect-VIServer : No such device or address

    At line:1 char:1

    + Connect-VIServer -Server 10.xx.xxx.xx -User mu****@vsphere.local -P ...

    + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    + CategoryInfo          : NotSpecified: (:) [Connect-VIServer], CommunicationException

    + FullyQualifiedErrorId : System.ServiceModel.CommunicationException,VMware.VimAutomation.ViCore.Cmdlets.Commands.ConnectVIServer

    I am able to connect with same vSphere via powershell on my mac without any issue but i get the above error from CentOS.

    Please always use FQDNs when addressing vSphere resources, not IP addresses. What is this version of vCenter? You can ping it from this CentOS box, yes? Can you do a successful curl to it?

    Thanks daphnissov

    1. What is this version of vCenter  -

    2. You can ping it from this CentOS box - Yes

    3. Can you do a successful curl to it - Yes..curl -k https://10.xx.xxx.xxx, Also i can able to do the telnet & nc on this host with port 80 & 443.  As i mentioned earlier, I am able to build the connection with vCenter using IP address from Mac but not from CentOS. I think i am missing some settings / steps related to Linux that causes this issue????

    curl -v telnet://10.xx.xxx.xx:443

    * About to connect() to 10.xx.xxx.xx port 443 (#0)

    *   Trying 10.xx.xxx.xx...

    * Connected to 10.xx.xxx.xx (10.xx.xxx.xx) port 443 (#0)

    telnet 10.xx.xxx.xx 443

    Trying 10.xx.xxx.xx...

    Connected to 10.xx.xxx.xx

    Escape character is '^]'.

    curl -k https://10.xx.xxx.xxx

    Could this be a TLS version mismatch issue?

    Thanks guys for your support.

    I am unable to access the environment for a while, due to time restrictions I was forced to run it on a Windows machine.

    LucD previously I was able to access the vCenter with the Windows PowerShell, it would be weird on Linux since I've set to ignore certificate validation too.

    mkmr​ I'm using vCenter FQDNs, never had such kind of issue

    It would be interesting to check if you encounter the same issue when running this from Windows, but also under PowerShell v6.

    And yes, you can run those side-by-side on a Windows box.

    I have had a very similar issue.

    My solution was to disable proxy server configured on the Linux system.

    I am using opensuse 15, and pwsh + VMware.PowerCLI works fine.
