Adding FTP Servers
Figure 6. Add FTP Server
Using Secure FTP
In Portal Server v4.2 or higher, VBrick's FTP client supports secure FTP connections from
the end user (client), Portal Server and NVR to the VOD servers. This is accomplished using
FTP over SSL (FTPS protocol). Having a client that supports FTPS however, is not enough
to have secure FTP connections throughout the system. The FTP servers on all VOD servers
also need to support FTPS for a secure connection to exist. If a secure connection cannot be
established, the client will revert to the standard FTP protocol. The FTP server on Windows
platforms (IIS) does not currently support FTPS. Therefore, to have secure connections, you must
install a third-party add-in on all Windows VOD servers. Of the various solutions available,
VBrick recommends FTP Guardian. FTP Guardian is a wrapper for IIS that serves as a proxy
between a secure client and an unsecured IIS. You change the FTP port of IIS to an arbitrary
port (10021 for example), then you start the FTP Guardian service. It binds to port 21 and all
incoming FTP clients communicate using a secure front that proxies the calls to IIS on port
10021. Be aware that this add-on, for Windows servers only, is not sold or supported by
VBrick. It requires a server wrapper and additional .dlls.

Creating a VOD-WM FTP Server
If you are using a VOD-WM-Enterprise or VOD-WM-Standard (Microsoft Windows Media)
server, you must install and configure a standard FTP server on the VOD-WM server as
explained below. (For more about Microsoft Windows Media servers see ETV VOD Servers
on page 6.)
