(SQL Server) Get SSH Server Authentication Methods

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

This example requires Chilkat v9.5.0.78 or greater.

Chilkat ActiveX Downloads ActiveX for 32-bit and 64-bit Windows

-- Important: See this note about string length limitations for strings returned by sp_OAMethod calls.

CREATE PROCEDURE ChilkatSample
AS
BEGIN
    DECLARE @hr int
    DECLARE @iTmp0 int
    -- Important: Do not use nvarchar(max).  See the warning about using nvarchar(max).
    DECLARE @sTmp0 nvarchar(4000)
    -- This example requires the Chilkat API to have been previously unlocked.
    -- See Global Unlock Sample for sample code.

    DECLARE @ssh int
    -- Use "Chilkat_9_5_0.Ssh" for versions of Chilkat < 10.0.0
    EXEC @hr = sp_OACreate 'Chilkat.Ssh', @ssh OUT
    IF @hr <> 0
    BEGIN
        PRINT 'Failed to create ActiveX component'
        RETURN
    END

    -- To get the authentication methods offered by an SSH server, we first connect.
    DECLARE @success int
    EXEC sp_OAMethod @ssh, 'Connect', @success OUT, 'example.com', 22
    IF @success <> 1
      BEGIN
        EXEC sp_OAGetProperty @ssh, 'LastErrorText', @sTmp0 OUT
        PRINT @sTmp0
        EXEC @hr = sp_OADestroy @ssh
        RETURN
      END

    -- Next, we call GetAuthMethods to receive a comma separated list of authentication methods
    DECLARE @authMethods nvarchar(4000)
    EXEC sp_OAMethod @ssh, 'GetAuthMethods', @authMethods OUT
    EXEC sp_OAGetProperty @ssh, 'LastMethodSuccess', @iTmp0 OUT
    IF @iTmp0 <> 1
      BEGIN
        EXEC sp_OAGetProperty @ssh, 'LastErrorText', @sTmp0 OUT
        PRINT @sTmp0
        EXEC @hr = sp_OADestroy @ssh
        RETURN
      END

    -- For example: publickey,password,keyboard-interactive

    PRINT '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..
    DECLARE @success int
    EXEC sp_OAMethod @ssh, 'Connect', @success OUT, 'example.com', 22
    IF @success <> 1
      BEGIN
        EXEC sp_OAGetProperty @ssh, 'LastErrorText', @sTmp0 OUT
        PRINT @sTmp0
        EXEC @hr = sp_OADestroy @ssh
        RETURN
      END
    EXEC sp_OAMethod @ssh, 'AuthenticatePw', @success OUT, 'myLogin', 'myPassword'
    IF @success <> 1
      BEGIN
        EXEC sp_OAGetProperty @ssh, 'LastErrorText', @sTmp0 OUT
        PRINT @sTmp0
        EXEC @hr = sp_OADestroy @ssh
        RETURN
      END


    PRINT 'SSH Authentication successful.'

    -- ...

    EXEC sp_OAMethod @ssh, 'Disconnect', NULL

    EXEC @hr = sp_OADestroy @ssh
