Ports used by RU Server
Viewer
Viewer is a single "command center" used by a support technician/admin. The Viewer is where you keep your address book, start remote sessions and manage your licenses.
Host
The Host is a remote module installed on a target (i.e. remote) PC. This module works for both unattended and attended access.
Admin console
The Admin Console is a GUI dashboard that allows you to administer RU Server and monitor currently active and idle Viewers and Hosts connected to the Server. You can also use the Admin Console menu to open the Server's address book manager.
RU Server uses two ports — TCP 5655 as communication port and TCP 5670 for server administration.
Communication port
By default, RU Server communicates with Viewer and Hosts through a single TCP port 5655:
| Module | Port | Direction |
|---|---|---|
| RU Server | TCP 5655 |
Inbound |
| Viewer | TCP 5655 |
Outbound |
| Host | TCP 5655 |
Outbound |
You can change the port or even set multiple ports. For more information, see Server configuration.
Administration port
You can remotely connect to a running RU Server from another computer using Admin Console. By default, TCP port 5670 is used:
| Module | Port | Direction |
|---|---|---|
| RU Server | TCP 5670 |
Inbound |
| RU Server Administrator Console | TCP 5670 |
Outbound |
For more information, see Using Admin Console.
Tip
You can change communication and administration ports in the RU Server Configuration dialog. If you change the default communication port values, remember to update the corresponding port values in your Viewers and Hosts since the communication port is needed for the program's relay and sync functions to work.
