vCenter Server Appliance 6.x t WinSCP Appliance shell BASH

When you copy files using WinSCP, part of the operation happens on the target Linux system. The default Appliance Shell cannot be the remote partner of WinSCP. You must enable the Bash shell on the appliance, as follows: 

1. Initiate an SSH connection to the vCenter Server Appliance.
2. Provide the root user user name and password when prompted.
3. Run this command to enable the Bash shell:
   
   shell.set --enable True
   
4. Run this command to access the Bash shell:
   
   shell
5. In the Bash shell, run this command to change the default shell to Bash:
   
   chsh -s /bin/bash root
6. Use WinSCP to upload the certificate files to the vCenter Server Appliance.
7. To return to the Appliance Shell, run this command:
   
   chsh -s /bin/appliancesh root
