Is there a way to change security settings of an ESXi (6.7u2) via CLI ? Standard advanced settings can be modified by the following command :

esxcli system settings advanced set -o /Mem/ShareForceSalting -i 2 

Or kernel settings can be change with the command :

esxcli system settings kernel set -s hyperthreading -v FALSE 

But I can't fin a way to change security parameters from CLI (it's okay with GUI). For instance, I'm unable to change theses parameters from CLI :

  • Security.AccountUnlockTime
  • Security.AccountLockFailures
  • ...

Can someone help on that ?

  • What is the full property name for ShareForceSalting? I would imagine it would be something like Memory.SharedForceSalting? – Ramhound May 26 '20 at 14:06
  • The full property name is Mem.ShareForceSalting. – BDR May 26 '20 at 14:07
  • I assume you tried /Security/ShareForceSalting? – Ramhound May 26 '20 at 15:04
  • Yes, and the error is : Unable to find branch Security. – BDR May 27 '20 at 6:46

The security settings are not listed in available parameters with

esxcli system settings advanced list | grep “Security”.

I haven’t found also in other namespaces like security and account.

But you can manage this settings via PowerCLI :

Set-VMHostAdvancedConfiguration Security.AccountLockFailures -Value 10

Set-VMHostAdvancedConfiguration Security.AccountUnlockTime -Value 100

  • Thank you for your anwser. I've already seen the PowerCLI solution but in fact I have no administration machine and no guest machine (when I need to secure the ESXi). I need to look into vim-cmd options. – BDR Jun 11 '20 at 20:32
