Comtech EF Data VMS v3.12.x Vipersat - Manual (Page 81)

Chapter 2 - VMS Installation 2-41
MN/22156, rev 12 VMS Web Services Installation & Configuration
Requests and responses transmitted between the web application and the web
service use SOAP over HTTP protocol. The SOAP request is translated into an
RPC call into the VOS and the response is then returned to the web application.
This response is transformed into HTML and sent back to a web browser that
presents the user interface to the operator.
The ViperView client communicates directly with VOS using DCOM/RPC
protocols. ViperView is used by the Central Network Operator for administra-
tive functions, such as creating VNO networks and other resources in the
network.
For additional information and details on the client applications, refer to the
VNO Quick Start Guide and the ArrangeLink User Guide.
SOAP Server Prerequisites
The following items are required when installing the SOAP Services onto the
server:
• Windows Server 2008 operating system recommended, with current
Service Pack.
• Microsoft Internet Information Services (IIS), current version, to provide
Web server capabilities over an intranet, the Internet, or an extranet. This
allows other PC workstations to access the web services remotely.
• Microsoft ASP.NET, current version.
• Full VMS Install.
• If a firewall is installed on the server, it must be turned off or set correctly
to allow HTTP.
• The SOAP server must be on the same LAN and have either direct access
or an Ethernet connection to the VMS server(s).
• The SOAP server must be on the same domain as the VMS server(s).
• The installer must have administrator privileges on the server.
Caution: Running SOAP Services on a machine enables that machine to act
as an HTML server which may increase its vulnerability when
connected to the Internet.
