Prerequisites for Sharing Computers Remotely

You can access computers of remote computers, in a Local Area Network (LAN) or in a Wide Area Network (WAN), to complete various tasks. Desktop Central supports remote desktop sharing for both Windows and Mac operating systems.

Ensure that the following prerequisites are met before you access computers remotely:

  1. Configure Browser Settings

    1. Configuring Mozilla Firefox or Flock to Install Desktop Central Add-ons

    2. Installing Java Plug-ins in Browsers

  2. Ports that need to be open

  3. Configuring Remote Control for Mac

Configuring Browser Settings

You are required to configure certain controls in your browser before connecting remotely to a computer. For example, if you are using an ActiveX viewer, in Mozilla Firefox, to view the remote computer, you must install Java Plug-ins in the browser you are using.

  • Ensure that you configure controls only in the browser from where a remote connection is being established.

  • HTML 5 Viewer is supported on the following versions of the browser: Edge (all versions), Internet Explorer 10 and later versions,  Firefox 38 and later versions, Google Chrome 31 and later versions and Safari 8 and later versions.

Configuring Mozilla Firefox or Flock to Install Desktop Central Add-ons

Before you use either Mozilla Firefox or Flock to establish a connection with a computer remotely, you must configure the browser settings to allow you to install Desktop Central add-ons in it.

To configure Mozilla Firefox or Flock to enable you to install Desktop Central add-ons in it, follow the steps given below:

      1. On the Tools menu, click Options

      2. Click the Security tab

      3. Enable the Warn me when sites try to install add-ons option

      4. Click Exceptions

      5. In the Allowed Sites section, add the name or the IP Address of the machine where the Desktop Central server is installed

      6. Click Allow

      7. Click Close

      8. Click OK to close the Options property sheet

You have configured Mozilla Firefox or Flock to enable installation of Desktop Central add-ons. Now you can install the required Desktop Central add-on. When you've installed the required add-ons, you can connect remotely to computers.

Installing Java Plug-ins in Browsers

If you are using a Java Viewer or browsers like Safari/Google Chrome/Fire Fox, (other than Internet Explorer),  then you will have to install the Java plug-ins to establish remote connection. If Java plug-ins are already installed, the connection will be established  automatically. However, if the required Java plug-ins are not installed, you will be prompted to download and install them to connect to a remote computer.

You can download and install Java plug-ins from http://www.oracle.com/technetwork/java/index.html. You may have to restart the browser after installing the plug-ins. Ensure that your browser does not block the Java Viewer pop-ups.  

Ports that need to be open

The following TCP ports should be open on the Desktop Central server to establish connection with a remote computer:

Ensure that the above mentioned ports are opened on the Desktop Central server , and the ports are reachable from the Desktop Central agent as well as the viewer machine.

Configuring Remote Control for Mac

If you wanted to establish connection with a Mac computer, which runs Mac OS X version 10.10 (Yosemite) or above, then  You will have to download and  install Apple jre from here: https://support.apple.com/kb/DL1572?viewlocale=en_US&locale=en_US. This is also available under software templates, on the Desktop Central web console : Java for OS X 2015-001

Ensure that the Non SSL RDS Port is reachable from the Desktop Central agent, even if you have chosen to use Secured connection.

 

You can now configure the settings required for establishing remote connection.
