Received too large SFTP packet error when using WinSCP to connect to vCenter appliance
This is because the appliance shell is set as the default for root (which is expected), to resolve it you need to change the default to bash by following the below:
SSH To the vCenter and run:
chsh -s /bin/bash root
You should now be able to use WinScp
If you wish to change it back to the appliance shell run this command:
chsh -s /bin/appliancesh root
