You can use SSH to log in remotely to the ESXi Shell and perform troubleshooting tasks for the host.
The SSH configuration in ESXi uses the following settings:
- Version 1 SSH protocol disabled
- VMware does not support Version 1 SSH protocol and uses Version 2 protocol exclusively. Version 2 eliminates certain security problems present in Version 1 and provides you with a safe way to communicate with the management interface.
- Improved cipher strength
- SSH supports only 256-bit and 128-bit AES ciphers for your connections.
These settings are designed to provide solid protection for the data you transmit to the management interface through SSH. You cannot change these settings.
