Some of my colleagues and I have been presenting a vCloud training session today, and one of the students got the error “Peer not Authenticated” when deploying a vApp. To diagnose the problem, first we need to turn on debugging in vCloud Director. We do this by following the steps below: Select System Click the Administration Button Select General Enable the checkbox next to “Display Debug Information” Peer not Authenticated debug information Going back and looking at the error we see a lot more information. Now looking at this error you can see that it is an issue with SSL. This error can be resolved by disabling the checking of vCenter and vShield certificates. To do this follow the steps below: Select System Click the Administration Button Select General Scroll down until you see Certificates Remove the ticks from the checkboxes for “Verify vCenter and vSphere SSO certificates” and […]

How To: Disable warnings when SSH enabled vSphere ESXi 5.0
I previously wrote an article about how to enable SSH in vSphere 5.0. A few people have asked how to disable the warnings that then appear on the hosts when you have this feature enabled. The VMware KB article Cluster warning for ESXi Shell and SSH appear on an ESXi 5 host explains how to disable this warning. The following steps explain how to disable this warning: Select the ESXi host from the Inventory. Select Advanced Settings from the Software menu. Navigate to UserVars > UserVars.SuppressShellWarning. Set the value from 0 to 1. Click OK.
HowTo: Enable SSH on vSphere ESXi 5.0
Back in 2010 and I wrote a quick article on How To: Enable Remote Tech Support mode and SSH on ESXi 4.1. A few people have posted comments asking if I could do the same now that vSphere/ESXi 5.0 has been released. The actual steps haven’t really changed, however Remote Tech Support mode is now just simply called SSH. The steps listed below explain how to enable SSH on an ESXi 5.0 host. Login to vCenter Select your host Click the configuration tab Select Security Profile under Software Click Properties for Services Select SSH and click options Choose the startup policy that you require Click Start Click OK and OK SSH to your host Once enabled you will notice that the host within vCenter has a warning being shown. When selecting that host, and looking under the summary, vCenter alerts you to the fact that SSH is enabled.
Enable ESXi Shell vSphere 5.0
Today I was playing around with building some virtual ESXi hosts and could not get one of them onto the network. I tried everything I could through the console UI, but knew I had to enable the ESXi shell command line to do some further digging. These are the steps that I carried out to do this: Connect to the ESXi host console Hit F2 Enter the username and password Select Troubleshooting Options Select Enable ESXi Shell and hit return Press Escape to exit Hold Alt and press F1 Login to the ESXi shell Once logged in you will see the command line If you are unsure of the commands to use the document Command-Line Management in vSphere 5.0 for Service Console Users is a really good starting point.
HowTo: Enable SSH and Remote Tech Support mode on ESXi 4.1
A couple of days ago I posted an article that has been produced hundreds of times about Enabling ssh on ESXi – pre 4.1. Today I thought I would post a quick how-to about enabling it via vCenter on ESXi 4.1. This drastically makes life easier, because you neither have to edit config files via the cLI nor do you need access to server consoles either remotely or physically. 1) Log in to vCenter 2) Select your host 3) Click the configuration tab 4) Select Security Profile under Software – You will be shown the services that are available for configuration 5) Click Properties 6) Highlight Remote Tech Support (SSH) and click options 7) Choose the Startup policy and Service Command that you require. 8 ) Click Ok 9) Click Ok 10) Open up a SSH session to your host and login Once enabled you will notice that the host […]
