Failed connection attempt troubleshooting checklist (sender)

Use the following checklist to troubleshoot failed connection attempts from the sender side:

1. Verify the credentials for the user account you are trying to access from the receiver. The account

password cannot be blank.

2. Verify that RGS Sender has started on the sender (see RGS Sender overview on page 21 for more

information).

3. Verify that all tests pass on the Diagnostics panel of the RGS Sender Conguration tool.

4. If the sender is behind a rewall, verify that the rewall supports network address translation (NAT) and

port forwarding.

5. If you changed the network interface binding of RGS Sender from its default of listening to all network

interfaces, verify that the sender is listening on the correct network interface (see RGS Sender network

interface binding on page 66 for more information).

6. (Windows only)

Verify that the sender is not using Automatic Private IP Addressing (APIPA) by typing the following in a

command window:

netstat -n -a

If the IP address associated with the RGS Sender listening port (42966 by default) is private, APIPA is the

likely cause. For information about how to disable APIPA, go to http://support.microsoft.com/kb/

220874.

7. (Linux only)

Verify that the sender is not using an X desktop started on the command line. Outside connection

attempts might fail because of incomplete PAM session management and permissions for the console.

NOTE: Make sure you log out of the sender before attempting an RGS connection again.

RGS Sender network interface binding

RGS Sender is set by default to listen to all network interfaces present on the sender. If this is undesirable, the

network interface binding can be manually recongured.

There are three methods to recongure RGS Sender network interface binding:

●

Disable the network interfaces that you do not want RGS Sender to listen to, and then restart the sender.

RGS Sender will then bind to the remaining enabled network interface. The disadvantage of this method

is that the other network interfaces will no longer be usable.

●

Manually congure the desired network interface to be the one listened to by RGS Sender. See

Reconguring network interface binding manually on page 67 for more information.

●

Use the RGS Sender Conguration tool to specify which network interface to listen to. See Reconguring

network interface binding using the RGS Sender Conguration tool on page 67 for more information.

If you enter a hostname instead of an IP address when establishing an RGS connection, it is possible that the

hostname will resolve to the IP address of an incorrect network interface. This could be caused by a number

of factors, including how your DHCP and DNS servers are congured.
