(SQL Server) SFTP using HTTP Proxy

Demonstrates how to connect to an SFTP/SSH server through an HTTP proxy.

Chilkat ActiveX Downloads

ActiveX for 32-bit and 64-bit Windows

CREATE PROCEDURE ChilkatSample
AS
BEGIN
    DECLARE @hr int
    DECLARE @sTmp0 nvarchar(4000)
    -- This example assumes the Chilkat API to have been previously unlocked.
    -- See Global Unlock Sample for sample code.

    DECLARE @sftp int
    EXEC @hr = sp_OACreate 'Chilkat_9_5_0.SFtp', @sftp OUT
    IF @hr <> 0
    BEGIN
        PRINT 'Failed to create ActiveX component'
        RETURN
    END

    -- To connect through an HTTP proxy, set the HttpProxyHostname
    -- and HttpProxyPort properties to the hostname (or IP address)
    -- and port of the HTTP proxy.  Typical port numbers used by
    -- HTTP proxy servers are 3128 and 8080.
    EXEC sp_OASetProperty @sftp, 'HttpProxyHostname', 'www.my-http-proxy.com'
    EXEC sp_OASetProperty @sftp, 'HttpProxyPort', 3128

    -- Important:  Your HTTP proxy server must allow non-HTTP
    -- traffic to pass.  Otherwise this does not work.

    -- Connect to the SSH server through the HTTP proxy.  
    DECLARE @success int
    EXEC sp_OAMethod @sftp, 'Connect', @success OUT, 'sftp.example.com', 22

    -- Your application is now connected to an SFTP/SSH server 
    -- through an HTTP proxy. 
    -- ..
