1 1 Introduction What is DeTOS? Devon IT Terminal Operating System (DeTOS) is an embedded Thin Client Operating System designed to be simple, secure, and centrally manageable. DeTOS can be used to access hosted desktops using Microsoft Remote Desktop Services, VMware Horizon View, Citrix XenApp or XenDesktop, web-based applications, and more. DeTOS Features Simple-Configuring a session out of the box is quick and painless using the DeTOS intuitive web based control panel.
Echo allows you to update the thin client’s embedded OS. Updates can be scheduled to happen outside of production hours, for example over the weekend. DeTOS Installation No installation is required for customers who have purchased DeTOS based thin clients from Devon IT. Your thin client already contains a factory installed DeTOS operating system. A USB re-flash utility is available if you need to reinstall the operating system at any point in the future.
2 2 Getting Started To get started, do the following: Check that your thin client is connected to the network. If you have set up a management server in your network, check that the thin client was able to contact the management server and is in managed mode. Create a desktop shortcut to allow thin client users to get connected to a remote server. (See Chapter 6, “Connections,” for more information.) To check the network connection status, click the DeTOS button and then select Control Panel.
DeTOS default factory setting is DHCP. If you have a DHCP server on your network, the status bar should show the leased IP address. If you want the thin client to use a fixed IP address please refer to this guide's network section. A message of no ip address will appear if network connectivity is lost or was never established in the first place. This may be related to a loose or faulty network cable. It may also be an indication of DHCP issues.
Management Server Indicator Once you are on the DeTOS Desktop, the Echo Agent running on your terminal will continue to periodically contact a Management Server named ws-broker on your local area network. When successful, the Management Server Indicator box found along the bottom of the Control Panel will read Managed. Otherwise, the icon will change to a red circle and the status will say Unmanaged. In this case, verify that your management server is online and accessible on your LAN.
Network Tools The toolbar along the top of the Control Panel window contains a button named Network Tools. Clicking this button will open a separate, smaller window that provides you with current network status and useful diagnostic programs. Interface Status Click the Interface Status tab along the top of the Network Tools window to view the IP address that is currently assigned to this terminal. The MAC Address for this machine is also reported on this screen.
3. If there is an error in the delivery to the destination, the ping command displays an error message. Otherwise, replies will continuously display for each packet successfully sent and received. 4. Press the Stop button to terminate the ping loop. Echo Agent System Information Echo Management- Displays the current status and information of the Echo Management server to which your thin client is connected. Management Status-Displays when the thin client is being managed by an Echo server.
Operating System-Displays the name of the image or operating system that is in use. Processor-Displays the processor that the thin client is using. Memory-Displays the total internal memory of the thin client. DOM Size-Displays the total storage capacity size of the thin client. Hardware Model-Displays the name of the thin client in use.
Persistence Persistence, within the scope of thin client computing, refers to the continuing existence of connections and settings after a terminal has been rebooted. Upon completion of the first boot wizard, a snapshot of the thin client is taken and saved in a data partition for basic settings. All of the connections, settings, and network settings assigned during the first boot wizard will be saved to the Echo server once this snapshot is taken and they will persist and carry over after a reboot.
3 3 System Settings Display Settings This section describes the display options available for a single monitor attached to a terminal. From the DeTOS desktop, select DeTOSControl Panel. Click the Display icon on the left-hand side of the Control Panel, under System Settings. Screen Resolution-Your screen resolution is set to automatically detect the optimal settings for your monitor.
Color Depth-The Ceptor supports a color depth of 24 bit. Enable Screen Blanking-Checking this box will reveal two timeout values for screen blanking and suspend time. Once you are finished, press the Apply button for the changes to take effect. Input/Time This section allows you to configure keyboard, mouse, and time settings for the terminal. From the DeTOS Desktop, select DeTOSControl Panel. Select the Input/Time icon on the left-hand side of the Control Panel under System.
Time Zone-The time zone options are organized geographically by region first and then by city. Select the appropriate time zone for your location. Timeserver-Defining a timeserver allows the terminal to query an NTP service in order to keep its date and time in sync. By default, this is enabled and set to Ubuntu's timeserver. Press the Apply button for the changes to take effect. Most settings will be changed immediately, but changes to system locale will require a reboot.
Management Management Server Configuration During bootup, if the thin client cannot make contact with a Management Server, then a white splash screen will appear just prior to the DeTOS desktop loading. This screen contains a message saying Attempting to connect to Management Server. The splash screen will be displayed until successful contact is made with a management server, the cancel button is pressed, or the specified timeout (30 seconds by default) is reached.
Server Address-While in managed mode, the thin client will maintain contact with a management server named ws-broker. Use this field to specify a different hostname or IP address for your management server. Splash Screen – Timeout-Use this field to adjust the number of seconds the splash screen appears on the screen before it times-out and loads the DeTOS Desktop. Enter a value of 0 to bypass the screen altogether.
Enter a password in the password field and re-enter it to confirm your password. Press the Apply button to save your password. NOTE: Once a system password is set, the user will be prompted for the password when they attempt to open the Control Panel. If the Cancel button is pressed or a user incorrectly types the password, then the Control Panel will open in a read-only mode. A small padlock icon will also appear along the bottom of the Control Panel window, indicating that edits are not allowed.
Network Settings By default, the thin client attempts to contact a DHCP server on your network during bootup. If you have a DHCP server on your network, then the thin client will acquire an IP address automatically and no further network configuration is required on your part. However, there are additional options available. Thin clients capable of connecting to wireless networks will still default to a wired connection if available.
Sounds This section allows you to adjust the master volume level for the terminal. From the DeTOS Desktop, select DeTOSControl Panel. Click the Sound icon on the left-hand side of the Control Panel under System. Left-click and drag the bar left or right to decrease or increase the volume. Press the Apply button to save. Your changes will take place automatically. USB Permissions This section allows you to adjust what USB capabilities the user of the device is able to access.
4 4 Advanced Options Export Config If you are working with a Devon IT Support Analyst to troubleshoot a problem on your terminal, you may be asked to send your terminal's Config file. You can easily export your own Config file by following these steps: 1. Plug a USB flash drive into the terminal. 2. Click the button found along the top of the Control Panel named Export Config. 3. The process only takes a few seconds.
Manage Packages In the upper toolbar of the DeTOS Control Panel is a button that says Manage Packages which opens the DeTOS Package Manager. This tool can be used to enable or disable individual update packages that may be made available, as well as customization packages. These packages will be in a squashfs file type and can be provided by Devon IT. There are two methods of locating the files to be added to the list of available packages.
2. Navigate to the location of the update package on your system or USB key and select Open. The package you have selected will now appear in the DeTOS Package Manager menu. In order to add a package that is not locally stored: 1. Click on the Add URL button in the DeTOS Package Manager. 2. Enter the complete URL for the location of the update package, using either FTP or HTTP protocol.
3. If necessary, enter the Username and Password needed to access the location where the file is held. 4. Click Ok. The package will now appear in the DeTOS Package Manager menu.
Newly added update packages will default to the Enabled status. In the DeTOS Package Manager, clicking the checkbox next to a file in the table under the Enabled column will toggle it between being enabled or disabled. Any changes to this status require a reboot before they will take effect. In order to completely remove a package: 1. Select the file you wish to remove from the table. 2. Click the Remove button. 3. A prompt will appear to ensure that this is what you want to do.
