SSHAuth Component
Properties Methods Events Configuration Settings Errors
The SSHAuth component provides a simple way to authenticate a user against a SSH server.
Syntax
nsoftware.IPWorksAuth.Sshauth
Remarks
The SSHAuth component offers a simply way to authenticate a user against a SSH server.
To begin specify the SSHHost, User, and Password. Next call Authenticate to authenticate the user.
The component supports multiple authentication methods including public key authentication, keyboard interactive authentication, password authentication, and more. Set AuthMode to the desired authentication mechanism before calling Authenticate.
