Pascal (Lazarus/Delphi)

Get SSH Server Authentication Methods

See more SSH Examples

Demonstrates how to get the authentication methods of an SSH server.

This example requires Chilkat v9.5.0.78 or greater.

Pascal (Lazarus/Delphi)

// Demonstrates using the Chilkat Pascal wrapper via the C bridge DLL.
// Builds as a console application under Lazarus (FPC) or Delphi.

  Chilkat.Ssh;

// ---------------------------------------------------------------------------

procedure RunDemo;
var
  success: Boolean;
  ssh: TSsh;
  authMethods: string;

begin
  success := False;

  //  This example requires the Chilkat API to have been previously unlocked.
  //  See Global Unlock Sample for sample code.

  ssh := TSsh.Create;

  //  To get the authentication methods offered by an SSH server, we first connect.
  success := ssh.Connect('example.com',22);
  if (success <> True) then
    begin
      WriteLn(ssh.LastErrorText);
      Exit;
    end;

  //  Next, we call GetAuthMethods to receive a comma separated list of authentication methods
  authMethods := ssh.GetAuthMethods();
  if (ssh.LastMethodSuccess <> True) then
    begin
      WriteLn(ssh.LastErrorText);
      Exit;
    end;

  //  For example: publickey,password,keyboard-interactive
  WriteLn('Authentication methods suported by this serve: ' + authMethods);

  //  IMPORTANT:
  //  Getting the authentication methods will intentionally disconnect from the server.
  //  We'll need to re-connect, etc. to continue..

  //  For example..
  success := ssh.Connect('example.com',22);
  if (success <> True) then
    begin
      WriteLn(ssh.LastErrorText);
      Exit;
    end;
  success := ssh.AuthenticatePw('myLogin','myPassword');
  if (success <> True) then
    begin
      WriteLn(ssh.LastErrorText);
      Exit;
    end;

  WriteLn('SSH Authentication successful.');

  //  ...

  ssh.Disconnect();
