Procedure Test
    Boolean iSuccess
    Handle hoSftp
    String sHostname
    Integer iPort
    String sTemp1

    Move False To iSuccess

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

    Get Create (RefClass(cComChilkatSFtp)) To hoSftp

    // To use a SOCKS4 or SOCKS5 proxy, simply set the following
    // properties prior to connecting:
    // The SOCKS hostname may be a domain name or 
    // IP address:
    Set ComSocksHostname Of hoSftp To "www.mysocksproxyserver.com"
    Set ComSocksPort Of hoSftp To 1080
    Set ComSocksUsername Of hoSftp To "myProxyLogin"

    // Connect to the SSH server.  
    // The standard SSH port = 22
    // The hostname may be a hostname or IP address.
