Back to basics… When you try connecting to vCenter Server Virtual Appliance 6.x (vCSA) using WinSCP, the error message ‘Received too large (1433299822 B) SFTP packet‘ might appear.
This is due to the configuration of vCSA when the default shell used for the root account set to the Appliance Shell.
To fix this issue, VMware recommends switching the vCSA 6.x to the Bash Shell. This can be done in the SSH session with the following command:
chsh -s /bin/bash root
Note: You need to log out from the Appliance Shell and log in back again for the changes to take effect.
