You can add custom menu items or even whole tabs to the main window using the Citrix Hypervisor Center plug-in. For example, you might do this action as an ISV to integrate your own product with Citrix Hypervisor Center, or as an end-user to integrate with your company’s existing inventory management. A menu item can run a Microsoft PowerShell script or even an arbitrary executable on the client machine. Tabs are populated with a webpage, and can call out to other services on your network or to your VMs.

  • An XML configuration file.
  • A resource DLL for each supported locale.
  • The application and any resources it requires.

By default, the host key is the right Ctrl key on your keyboard. You can change this default here. Right Ctrl

You can switch to RDP when it becomes available. On

Any changes you make to the Windows Remote Desktop console settings apply when you restart Citrix Hypervisor Center.

Connection settings

Proxy server

Citrix Hypervisor Center can be configured to connect directly to your managed servers or to use a proxy server. You can use your Internet Explorer proxy server settings, or you can specify a proxy server.

  • Select Don’t use a proxy server to have Citrix Hypervisor Center connect directly to managed servers without using a proxy server.
  • Select Use proxy server settings from Internet Explorer to use the same proxy settings as Internet Explorer.
  • Select Use this proxy server if you want Citrix Hypervisor Center to connect to the specified proxy server. Use HTTP CONNECT to establish a secure TLS tunnel to your servers. Enter the address of the proxy server and the port number to use.

To have Citrix Hypervisor connection requests made directly and not through the proxy server, select the Bypass proxy server for Citrix Hypervisor connections check box. To have all connection requests made through the proxy server, clear the check box.

Citrix Hypervisor connection is any connection which provides communication between Citrix Hypervisor Center and the Citrix Hypervisor system, such as sending commands and using the console. A non-Citrix Hypervisor connection is something such as checking for updates.

Select the Provide credentials check box and enter the Username and Password that corresponds to a user account that is set up on the specified proxy server.

Select the desired authentication method: Basic or Digest (default).

Authentication method is used to authenticate to the proxy server. Select the same authentication method as the one the proxy server is set for.

For example, if the proxy server requests Citrix Hypervisor Center to authenticate using Digest, then Citrix Hypervisor Center fails to authenticate if the Basic authentication method is selected.

Default: Don’t use a proxy server

Connection timeout

You can specify how long to wait when establishing a connection with a managed server by adjusting the number of seconds to wait for a connection timeout. Do not set this value too low if you don’t want to receive many false alerts due to network-related problems.

Default: 20 seconds

External Tools settings

Citrix Hypervisor Center can launch an external SSH console that connects to a Citrix Hypervisor server. The supported external SSH console tools are PuTTY and OpenSSH. To use an external SSH console, ensure you have one or both of these tools installed on the system that hosts Citrix Hypervisor Center.

Use this tab to select whether to use PuTTY or OpenSSH to launch an SSH console and to configure the path to your selected tool.

By default, Citrix Hypervisor Center selects the installed tool. If both tools are installed, PuTTY is selected.

If you have not configured the path to your external SSH console tool, Citrix Hypervisor Center attempts on start to locate your PuTTY or OpenSSH installation and uses the paths it discovers.
