how can I mix authenticationmethods in FileServer componenent for users? and how can I change the order of Authentication methods?
here is the Authentication codesnipped:
private static void Sshd_Authentication(object sender, AuthenticationEventArgs e)
{
// make sure the user exists
FileServerUser user = sshd.Users[e.UserName];
if (user != null)
{
// if it's a 'public key' user, check the key
var userWithKey = user as SshUsers;
if (userWithKey != null && userWithKey.Key.Equals(e.Key)) // userWithKey.key is populated correct but: e.Key is empty!
{
e.Accept(userWithKey);
return;
}
// otherwise, check the password
if (user.CheckPassword(e.Password))
{
e.Accept(user);
return;
}
}
here is my FileServer instantiating:
const string sshdPpkFilename = "sshd.ppk";
const string sshdPpkPass = "pass";
const string sshdRootPath = "root";
sshd = new FileServer();
sshd.LogWriter = new ConsoleLogWriter(LogLevel.Debug);
sshd.Bind(FileServerProtocol.Tunneling);
sshd.Bind(FileServerProtocol.Shell);
sshd.Bind(FileServerProtocol.Sftp);
sshd.Settings.UseNativeFilesystem = false;
sshd.Settings.ShellEncoding = Encoding.UTF8;
sshd.Settings.MaxAuthenticationAttempts = 3;
sshd.Settings.SshParameters.EncryptionAlgorithms = SshEncryptionAlgorithm.AES;
sshd.Settings.SshParameters.AuthenticationMethods = SshAuthenticationMethod.Any;
sshd.Settings.SshParameters.Compression = true;
sshd.Settings.SshParameters.KeyExchangeAlgorithms = SshKeyExchangeAlgorithm.DiffieHellmanGroupExchangeSHA256 | SshKeyExchangeAlgorithm.DiffieHellmanGroupExchangeSHA1;
sshd.Keys.Add(new SshPrivateKey(sshdPpkFilename, sshdPpkPass));
// user with name/password:
sshd.Users.Add("admin", "gg", Path.GetFullPath(sshdRootPath), ShellType.Default);
// http://www.rebex.net/file-server/features/authentication.aspx - User with Public Key Auth.
sshd.Users.Add(new SshUsers("o", new SshPublicKey(Path.GetFullPath(@"test.pub")), Path.GetFullPath(sshdRootPath), ShellType.Default));
sshd.Authentication += Sshd_Authentication;
sshd.Start();
the user "admin" authenticates with password.
User "o" should authenticate by public key (Key is loaded, Fingerprint verified within Visual Studio Debugger), but the password prompt appear.
he last lines from log when user "o" is prompted for Password:
