5 (Optional) Verify that the virtual printing module can be loaded successfully.
a To verify that tprdp.so can be loaded by FreeRDP 1.1, run the following command:
sudo ln -s /usr/lib/vmware/rdpvcbridge/tprdp.so /usr/local/lib/i386-linux-
gnu/freerdp/tprdp-client.so
b To start Horizon Client with the virtual printing feature enabled, run the following command:
vmware-view --rdpclient=xfreerdp --xfreerdpOptions='/cert-ignore /vc:tprdp'
N The virtual printing feature is available if you use VMware Blast or PCoIP.
Enabling FIPS Mode
You can enable FIPS (Federal Information Processing Standard) mode so that the client uses FIPS-compliant
cryptographic algorithms when communicating with remote desktops.
I If you enable FIPS mode in the client, the remote desktop must have FIPS mode enabled as
well. Mixed mode, where only the client, or only the desktop, has FIPS mode enabled, is not supported.
To enable FIPS mode, make the following conguration changes:
1 Edit /etc/vmware/config and add the following lines:
usb.enableFIPSMode = "TRUE"
mks.enableFIPSMode = “TRUE”
2 Edit /etc/vmware/view-mandatory-config and add the following line:
View.fipsMode = ”TRUE”
3 Edit /etc/teradici/pcoip_admin.conf and add the following line:
pcoip.enable_fips_mode = 1
Configuring the PCoIP Client-Side Image Cache
PCoIP client-side image caching stores image content on the client to avoid retransmission. This feature is
enabled by default to reduce bandwidth usage.
The PCoIP image cache captures spatial, as well as temporal, redundancy. For example, when you scroll
down through a PDF document, new content appears from the boom of the window and the oldest content
disappears from the top of the window. All the other content remains constant and moves upward. The
PCoIP image cache is capable of detecting this spatial and temporal redundancy.
Because during scrolling, the display information sent to the client device is primarily a sequence of cache
indices, using the image cache saves a signicant amount of bandwidth. This ecient scrolling has benets
both on the LAN and over the WAN.
n
On the LAN, where bandwidth is relatively unconstrained, using client-side image caching delivers
signicant bandwidth savings.
n
Over the WAN, to stay within the available bandwidth constraints, scrolling performance is often
degraded unless client-side caching is used. In this situation, client-side caching can save bandwidth
and ensure a smooth, highly responsive scrolling experience.
By default this feature is enabled, so that the client stores portions of the display that were previously
transmied. The default cache size is 250MB. A larger cache size reduces bandwidth usage but requires
more memory on the client. A smaller cache size requires more bandwidth usage. For example, a thin client
with lile memory requires a smaller cache size.
