Blocked Ports and Processes Affecting MarkVision's Ability to Communicate over a Network
This article describes the
ports and protocols
used by MarkVision™ Professional (MVP). Any network firewall blocking these ports between any MVP version server and a client/remote device will break basic functionality, such as discovery, policies, job accounting, etc.Identify the failing communication path for MVP and consult or contact your firewall provider or manufacturer for additional troubleshooting assistance.

Communication between clients and the MarkVision Server is based on
Java RMI (Remote Method Invocation
) technology. MVP uses randomly selected ports on the server to communicate to devices and MVP leaves the specifics of ports selection to the underlying java virtual machine. This facilitates its multi-threaded functionality.
NOTE:
The initial binding for a client-server session occurs on the 9188
port on the server side. All successive calls are made through Ephemeral ports on either side.MarkVision Client
Protocol
| MarkVision Client
| MarkVision Server
| Used for
|
RMI over TCP Remote Method Invocation over TCP | Ephemeral TCP port | TCP 9188 (Ephemeral port) | Establishing the initial RMI session Afterwards, successive communication is done through Ephemeral ports on both sides |
SLP | Ephemeral UDP port | UDP 9184 (Ephemeral port) | Client discovery of the MarkVision Server |
.
