To Configure the Linux agent settings follow the steps mentioned below.

    1. Click the Admin tab to invoke the Admin page.
    2. Click the Agent Settings link available under Global Settings.
    3. Select Linux Agent Settings tab
    4. Select the domain or the workgroup to group Linux computers (this is virtual grouping and will not impact on its functions).  Agents that are pushed remotely from Customers --> Add Computers will be shown under the respective Domain/Workgroup from which they are added.
    5. Click Save Changes to create Linux agents.


      Linux agents can be download from the Customers page, by choosing the appropriate agent, such as LAN agent or WAN agent for specific Remote offices.

Installing Desktop Central MSP Agents

Linux agents can be installed manually in the computers that need to be managed.  Agents should be downloaded on the Linux computer manually before initiating the installation process. Follow the steps mentioned below.

    1. Go to the terminal as a root user. If you do not login as a root user, open the terminal and use sudo command to perform each operation mentioned below and enter password whenever prompted. This provides you the root privilege.
    2. Navigate to the location, where the agent is downloaded and Unzip the DCLinuxAgent.zip by using the command "unzip -e DCLinuxAgent.zip".
    3. Verify if,  "DesktopCentral_LinuxAgent.bin" & "serverinfo.json" are located in the same path
    4. Execute the Command, "chmod +x DesktopCentral_LinuxAgent.bin" as a root user. This prepares the executable for installation.
    5. Run the Installer using "./DesktopCentral_LinuxAgent.bin". Agent will be installed by default in "/usr/local/desktopcentralagent" directory.
    6. If you wanted to change the installation location of the agent, use this command "./DesktopCentral_LinuxAgent.bin -d <new_location>" .

You can see that the Desktop Central agent is successfully installed on the Linux computer. You need to install the agents manually on the computers, which needs to be managed using Desktop Central. Once the agent installation is completed, the computer will be scanned automatically and the following details will be updated to the Desktop Central server:

        where username refers to the root user name of the target computer
        hostname refers to the local host name of the target computer
        If no path is specified, then the agent will be copied to "/home/username" in the target computer
