Pre-connection checklist 73

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.

IMPORTANT: 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 RGS Sender listens on TCP/IP port 42966. The port used by the RGS Receiver is assigned by the

Local Computer OS and can vary.

4-1 Local Computer (Receiver) checklist

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

1. 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,

resolve this problem before continuing.

2. 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.

4-2 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:

1. OPTIONAL: Ensure RGS Sender licensing is set up—Beginning at RGS 5.2.0, HP implemented licensing for

the RGS Sender. For an overview of RGS licensing, see Section 2-3, “RGS licensing

.” For detailed

information on RGS licensing, see the HP Remote Graphics Software Licensing Guide, available at

www.hp.com/support/rgs_manuals.

NOTE: Step 1 is optional because you can establish a connection from the Receiver to the Sender without a

Sender license. However, as shown in Figure 2-3, an error dialog will be displayed in the Remote Display

Window if the Sender license file is missing or invalid. If you don’t set up RGS licensing now, you can do it

after you’ve verified you can establish an RGS connection.

2. Ensure you have a login account on the Remote Computer—When establishing an RGS connection, the

Remote Computer will prompt you for a user name and password. Ensure that you have a login account on

the Remote Computer.

3. Verify the Remote Computer login account does not have a blank password—The Remote Computer will not

allow a connection for any account with a blank or undefined password. Any accounts on the Remote

Computer used for connection by the Local Computer must have password protection.
