4 Pre-connection checklist

Establishing an RGS connection from a Receiver to a Sender requires that the Local and remote

computers be in the correct state. This chapter provides a checklist of items that should be verified

before attempting an RGS connection.

NOTE: This chapter can also be used as a troubleshooting aid. If a connection attempt fails, the

checklists below can be used to help diagnose the problem.

NOTE: The port used by the RGS Receiver is assigned by the local computer OS and can vary. The

RGS Sender listens on TCP/IP port 42966 by default, but you can change the port number using the

Rgsender.Network.Port property. If this property is used to change the Sender port number from its

default value of 42966, the Sender port number must then be specified in establishing an RGS

connection from the Receiver to the Sender.

Local computer (Receiver) checklist

Verify the following items on the Receiver computer before attempting to establish a connection.

1. If using Advanced Video Compression, ensure the Receiver system meets the requirements

described in

Advanced Video Compression requirements on page 143 (essential for a quality

experience when using this feature).

2. Ensure that you are on the same network as the remote computer.

3. Verify the hostname or IP address of the remote computer—Verify that you have the correct

hostname or IP address of the remote computer. If the remote computer hostname fails to

resolve to the correct IP address, address this problem before continuing.

4. Verify that, from the local computer, you can ping the remote computer—If you’re unable to ping

the remote computer, you won’t be able to establish an RGS connection. Ping the remote

computer using the same computer designator you’ll be using to establish an RGS connection,

either the hostname or the IP address of the remote computer. Open a Command window and

execute either:

ping hostname

ping <IP address>

If no ping reply is received, the Sender computer is unreachable or is not running—resolve this

problem before continuing. If a ping reply is received, the Sender computer is reachable by

RGS.

NOTE: Ensure that firewall settings are not preventing the ping command from working.

Remote computer (Sender) checklist

Modification and verification of the Sender state can be performed either by connecting a keyboard,

mouse, and monitor directly to the remote computer, or by using Remote Desktop Protocol to log in

remotely to the remote computer. In either case, verify each of the following items:
