types of pam_unix*.so, pam_env*.so, common-auth, and pam_stack.so may apply to your
configuration for the /etc/pam.d/rgsender configuration file. If you choose to do all of your
own customizations manually, please run the rgsender_config_64*-rpm at least once on a
test system to determine an example of any customizations that you might need in your
current environment.
7. If another desktop manager, such as Enlightenment, is being used, you will need to make similar
changes to the PAM configuration file used by it. Consult your Linux and Desktop Manager
documentation for further information.
8. If the PAM system has been configured to use custom PAM authentication modules then you may
need to manually configure the PAM module that is used by the RGS Sender. You should consult
your Linux documentation when configuring PAM. If you are using a custom PAM authentication
module called “libpam_custom.1” you may need to edit the PAM configuration file "/etc/pam.d/
rgsender” to specify the PAM authentication module to be used by the RGS Sender. For example,
you may need to add the following line to the file "/etc/pam.d/rgsender”.
auth optional /lib/security/pam_custom.1
9. The RGS Sender will not accept remote connections when a DNS name inquiry does not resolve to
a valid/active IP address—the Sender expects to fully resolve the machine name to an active
network connection IP. To test this, the command hostname -i should report an active IP
address for the qualified hostname. Failure to resolve this address from a qualified hostname may
result in remote connection errors. One way to address the hostname/IP name resolution is to edit
the /etc/hosts file, and bind the machine name to its proper IP address as follows:
127.0.0.1 localhost localhost.localdomain
88.1.89.122 blade2 blade2.datacenter.com
10. If the Sender is being installed on the HP ProLiant xw460c Blade Workstation, the blade
workstation needs to be rebooted into User Mode after Sender installation is complete. For
information on selecting User Mode, refer to the document Administrator’s Guide for Linux on HP
ProLiant Blade Workstations, available at
http://www.hp.com/support/xw460c_manuals.
Linux Sender Audio
The RGS Sender will attempt to capture audio from the default audio device to be played back on the
RGS Receiver. The audio device on the Sender system needs to be configured appropriately to enable
audio capture. See
Configuring audio on Linux on page 132 for details on configuring the audio
device on a Linux sender.
The HP Blade Workstation does not have audio hardware. The Virtual Audio Driver can be used to
enable audio to be captured and played back on the RGS Receiver. The driver and appropriate
libraries need to be compiled and installed to match the current Linux kernel. The source code and
instructions for installation are in the virtual_audio_driver.tar file and can be found in the source
directory on the distribution disc.
Starting the Sender on Linux
The Linux Sender is started by the “rge” X server extension whose configuration is described in the
previous section. The Sender cannot be started manually. Proper configuration and startup of the
