Setting Up for Linux Desktops

Troubleshooting Horizon Agent on a Linux Machine That Is Not
Responding
Horizon Agent that is installed on a Linux virtual machine is not responding.
Problem
The Horizon 7 for Linux desktop is not accessible, and Horizon Agent is not responding.
Cause
The Horizon Agent service might not be running, or the X session might not be active on the Linux machine.
Solution
1 On the Linux virtual machine, open a terminal window and stop and restart the Horizon Agent service.
sudo service viewagent <stop/start/restart>
2 Verify that the X session is active.
ps –A | grep X
3 Install the X11 Simple VNC server on the virtual machine and verify that the X session is active over
VNC.
Troubleshooting Copy and Paste between Remote Desktop and Client
Host
Copy and Paste between the remote desktop and client host takes more than three seconds for maximum
supported data of 1 MB. This issue does not occur if you copy and paste a small data size.
Problem
When you configure 1 vCPU and 1 GB memory for SLED 11 SP3/SP4 desktop, it might take more than three
seconds to copy and paste between the remote desktop and local client host.
Cause
The delay in copy and paste might occur due to the old operating system APIs of SLED 11 SP3/SP4.
Solution
u
Configure two vCPUs and 2 GB memory for SLED 11 SP3/SP4.
Configuring the Linux Firewall to Allow Incoming TCP Connections
To allow users to connect to their Linux desktops, the desktops must be able to accept incoming TCP
connections from Horizon Client devices, security server, and View Connection Server.
On Ubuntu and Kylin distributions, the iptables firewall is configured by default with an input policy of
ACCEPT.
On RHEL and CentOS distributions, where possible, the Horizon Agent installer script configures the
iptables firewall with an input policy of ACCEPT.
Make sure that iptables on a RHEL or CentOS guest operating system has an input policy of ACCEPT for
new connections from the Blast port, 22443.
When the BSG is enabled, client connections are directed from a Horizon Client device through the BSG on a
security server or View Connection Server to the Linux desktop. When the BSG is not enabled, connections
are made directly from the Horizon Client device to the Linux desktop.
