Updating VCSA on a private network

Updating the VCSA is easy when it has internet access or if you can mount the update iso. On a private network, VMware assumes you have a webserver that can serve up the updaterepo files. In this article, we'll look at how to proceed when VCSA is on a private network where internet access is blocked, and there's no webserver available. The VCSA and PSC contain their own webserver that can be used for an HTTP based update. This procedure was tested on PSC/VCSA 6.0.

Follow these steps:

  • First, download the update repo zip (e.g. for 6.0 U3A, the filename is ) 
  • Transfer the updaterepo zip to a PSC or VCSA that will be used as the server. You can use Putty's pscp.exe on Windows or scp on Mac/Linux, but you'd have to run "chsh -s /bin/bash root" in the CLI shell before using pscp.exe/scp if your PSC/VCSA is set up with the appliancesh. 
    • chsh -s /bin/bash root
    • "c:\program files (x86)\putty\pscp.exe" VMware* root@psc-name-or-address:/tmp 
  • Change your PSC/VCSA root access back to the appliancesh if you changed it earlier: 
    • chsh -s /bin/appliancesh root
  • Make a directory for the repository files and unpack the updaterepo files there:
    • mkdir /srv/www/htdocs/6u3
    • chmod go+rx /srv/www/htdocs/6u3
    • cd /srv/www/htdocs/6u3
    • unzip /tmp/VMware-vCenter*
    • rm /tmp/VMware-vCenter*
  • Create a redirect using the HTTP rhttpproxy listener and restart it
    • echo "/6u3 local 7000 allow allow" > /etc/vmware-rhttpproxy/endpoints.conf.d/temp-update.conf 
    • /etc/init.d/vmware-rhttpproxy restart 
  • Create a /tmp/nginx.conf (I copied /etc/nginx/nginx.conf, changed "listen 80" to "listen 7000" and changed "mime.types" to "/etc/nginx/mime.types")
  • Start nginx
    • nginx -c /tmp/nginx.conf
  • Start the update via the VAMI. Change the repository URL in settings,  use http://psc-name-or-address/6u3/ as repository URL. Then use "Check URL". 
  • Afterwards, clean up: 
    • killall nginx
    • cd /srv/www/htdocs; rm -rf 6u3

P.S. I personally tested this using a PSC as webserver to update both that PSC, and also a VCSA appliance.
P.P.S. VMware released an update for VCSA 6.0 and 6.5 on the day I wrote this. For 6.0, the latest version is U3B at the time of writing, while I updated to U3A.

Volkswagen UHV bluetooth touch adapter & its problems

My Volkswagen car has the "universal cellphone preparation" UHV built-in. This is the main part of a car kit, but requires an additional adapter for connecting to a cellphone. At first, I was using an adapter for my good old Nokia 6310, even after I changed to the Nokia E71. Connecting was easy: pair the phone with the "VW UHV" bluetooth entity, and done. This has the phone connected to the car kit at all times, so even non-call-related functions use the car audio system (e.g. voice recognition). But progress will have its way, no matter what happens. So in comes the "bluetooth touch adapter". Instead of a phone-specific adapter, this is a small touchscreen device that slots into the UHV dashboard mount. Connecting a phone is very different now: the Bluetooth Touch Adapter connects to the "VW UHV" device via bluetooth the phone connects to "Touch Adapter" device, also via bluetooth The device doesn't allow step 2 if step 1 didn'

Reset lost root password on vSphere ESXi 6.7

VMware's solution to a lost or forgotten root password for ESXi is simple: go to  and you'll find that "Reinstalling the ESXi host is the only supported way to reset a password on ESXi". If your host is still connected to vCenter, you may be able to use Host Profiles to reset the root password, or alternatively you can join ESXi in Active Directory via vCenter, and log in with a user in the "ESX Admins" AD group. If your host is no longer connected to vCenter, those options are closed. Can you avoid reinstallation? Fortunately, you can. You will need to reset and reboot your ESXi though. If you're ready for an unsupported deep dive into the bowels of ESXi, follow these steps: Create a bootable Linux USB-drive (or something else you can boot your server with). I used a CentOS 7 installation USB-drive that I could use to boot into rescue mode. Reset your ESXi and boot from the Linux medium. Ident

How to solve "user locked out due to failed logins" in vSphere vMA

In vSphere 6, if the vi-admin account get locked because of too many failed logins, and you don't have the root password of the appliance, you can reset the account(s) using these steps: reboot the vMA from GRUB, "e"dit the entry "a"ppend init=/bin/bash "b"oot # pam_tally2 --user=vi-admin --reset # passwd vi-admin # Optional. Only if you want to change the password for vi-admin. # exit reset the vMA log in with vi-admin These steps can be repeated for root or any other account that gets locked out. If you do have root or vi-admin access, "sudo pam_tally2 --user=mylockeduser --reset" would do it, no reboot required.
