The Behavior tab has two checkboxes dedicated to the following settings:
- Allowing the insecure ssh-rsa key exchange algorithm during the key exchange;
- Reporting back to the clients errors that occur when changing some permissions.
The initial setting is designed for administrators to enable an insecure key exchange algorithm during the key exchange. Despite its inherent insecurity, in certain usage scenarios—such as when connecting clients are legacy programs—there might be a convenience factor in providing the option to enable it.
The second setting enables administrators to reintroduce error messages associated with unsuccessful attempts to set file permissions. This allows the client to gain more insight into why the operation did not succeed.
