    ; 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:
    CkSFtp::setCkSocksHostname(sftp, "www.mysocksproxyserver.com")
    CkSFtp::setCkSocksPort(sftp, 1080)
    CkSFtp::setCkSocksUsername(sftp, "myProxyLogin")
    CkSFtp::setCkSocksPassword(sftp, "myProxyPassword")

    ; Set the SOCKS version to 4 or 5 based on the version
    ; of the SOCKS proxy server:
    CkSFtp::setCkSocksVersion(sftp, 5)

    ; Note: SOCKS4 servers only support usernames without passwords.
    ; SOCKS5 servers support full login/password authentication.

    ; Connect to the SSH server.

    ; The hostname may be a hostname or IP address.
