Recently, a customer asked us:
If we move to using the INI configuration method instead of staging, would password-less SSH still be required?
The answer is both "Yes" and "No"
No, for installation and updates/upgrades specifically. Since INI-based configurations force the
tpm command to act upon the local host only for installs and updates/upgrades, password-less SSH is not required.
Yes, because there are certain commands that do rely upon password-less SSH to function. These are:
tpm diag --hosts(>= 6.0.5)
- Any tpm-based backup and restore operations that involve a remote node
In this blog post we discussed the SSH differences between the Staging and INI configuration methods.
