Setting Up for Linux Desktops

n
Select UDP if the network condition is poor, such as in a wide area network (WAN) environment with
packet loss and time delay.
Use a network analyzer tool, such as Wireshark, to determine whether VMware Blast Extreme is using
TCP or UDP. Use the following set of steps, which use Wireshark, as a reference example.
1 Download and install Wireshark on your Linux VM.
For RHEL/CentOS 6:
sudo yum install wireshark
For Ubuntu 14.04/16.04:
sudo apt install tshark
For SLE 11/12:
sudo zypper install wireshark
2 Connect to the Linux desktop using VMware Horizon Client.
3 Open a terminal window and run the following command, which displays the TCP package or UDP
package used by VMware Blast Extreme.
sudo tshark -i any | grep 22443
USB Redirection and Client Drive Redirection (CDR) features are sensitive to network conditions. If the
network condition is bad, such as limited bandwidth with time delay and packet loss, the user experience
becomes poor. In such condition, the end user might experience one of the following.
n
Copying remote files can be slow. In this situation, transmit smaller sized files instead.
n
USB device does not appear in the remote Linux desktop.
n
USB data does not transfer completely. For example, if you copy a large file, you might get a file
smaller in size than the original file.
VHCI Driver for USB Redirection
The USB redirection feature is supported beginning with Horizon 7 version 7.1 for Linux desktops. The
feature has a dependency on the USB Virtual Host Controller Interface (VHCI) kernel driver. You must
patch the VHCI driver to support USB 3.0.
The Horizon for Linux installer includes the VHCI driver binary for the default kernel of the supported
Linux distributions. The installer installs the VHCI driver when the USB redirection feature is selected.
Table 1‑8 lists the default kernel versions that the Horizon for Linux installer installs.
