HP Smart Zero Client, a first impression.In the end of 2. 01.Hewlett- Packard introduced a range of zero clients and described them as “the affordable, reprogrammable and to- smart- to- be- called- a- zero- client, clients”.The clients come in two forms; HP Zero Clients, which are unmanaged, and the HP Smart Zero Clients.An overview of the available products can be found on the HP website (link). Start Menu 7 Pro V3 65 Impala here. I had the opportunity to get some hands- on- experience with a HP t. HP Smart Zero Client) and the HP Automatic Update Server software. HP t. 51. 0The HP t. Flexible Thin Client is an affordable ($ 2. US HP price) thin client with a duo- core VIA Eden 1. Ghz processor, 2. GB memory, Via Chromotion. HD 2. 0 graphics adapter, gigabit LAN and optional 8. Wi. Fi adapter. Besides the HP Smart Zero operating system the device is also capable of running Windows® Embedded 2. Windows® Embedded 7 or HP Thin. Pro (Linux). The device boots in 2. After the operating system is booted a pre- configured system is displayed allowing the user to connect to any of the following environments: Citrix Xen. App Microsoft RDP VMware View The device is marked as “HDX Ready” and is capable of HDX Media. Stream 1. 28. 0*7. Quality Windows Media AND Flash Redirection. Details about the Citrix HDX Ready specifications and compatibility can be found here. The “Zero Client : No” remark on the Citrix site is interesting, the definition of a zero client appears to be flexible. More about the HP Smart Client being a zero client- or- not can be read in this article by Gabe Knuth. The user has the possibility to configure the device according his preferences, allowing it to configure the mouse, keyboard, screen, language, regional settings and of course the connection settings. Overall the HP Smart Zero operating system looks very good, its intuitive and well designed. Being “HDX Ready” and capable of client- side rendering of multimedia content makes it an interesting thin client. The out- of- the- box experience (OOBE) is very good and is similar to what the unmanaged HP Zero Clients can expect. Smart Client The HP Zero clients can be managed with Smart Client Service, a service that can be installed on a Windows operating system. In the HP Smart Zero operating system a user can click the information icon to see the status of the Smart Client Service. Out- of- the- box the Smart Client Service is not configured, clearly visible by the Exclamation mark in “About this client”. After configuring the service this will change to a green checkmark. More information can be found in the system logs. HP Smart Client Service (HP Automatic Update Server)The HP Smart Client is designed to detect its update server automatically and to configure itself automatically on first boot. This greatly simplifies device installation and maintenance. Refer to the following diagram to see how the device communicates with the server to receive its profile and client kits. Source: HP Smart Client Service – Administrators Guide Installation. Before the HP Automatic Update Server can be installed you need to install the following prerequisites: Internet Information Service (IIS) . NET Framework 3. 5 (this can done via the installer) The installation itself is pretty straightforward, the most important choice to make is the connection type that suits your needs. This connection type is provided by default to the clients, but it can be changed afterwards. Since my customer has a 2. X environment (…) I configured the Microsoft RDP connection type. Installed components. After the installation has completed successfully the following components are installed: HP Broadcast Server IIS Website “HP Automatic Update” Profile Editor HP Broadcast Server. After a Smart Client has booted it will search for a server that can provide him with updates. If this isn’t configured via DHCP (described below) a broadcast packet [1] is send over the network. Because a broadcast packet is used this will only work if the client is on the same subnet as the service (an IP helper might solve this). The Broadcast Server is a Windows NT service (started automatically) listens on UDP port 1. An exclusion in the Windows Firewall is made by the installation. The port on which the service listens can be changed in the registry key HKLM\SYSTEM\Current. Control. Set\Services\HP Broadcast Server\Port. The Broadcast Server returns the address of the IIS website [2] to the Smart Client. The returned URL is specified in the registry key HKLM\SYSTEM\Current. Control. Set\Services\HP Broadcast Server\Server. URL, by default this is set to http: //< local machine IP> :1. IIS Website “HP Automatic Update”Both the configuration as the boot- image files (the operating system) are supplied via a IIS website. The Smart Client connects via HTTP or HTTPS [3] to the web application and searches for updated files [4]. By default the IIS Websites listens on TCP port 1. IIS website. A web application with the name “auto- update” is mapped to %Installdir%\auto- update (by default %Program. Files%\Hewlett- Packard\HP Smart Client Service\auto- update), this is where both the configuration as the boot- image files are stored. Profile Editor. To configure the Smart Client a profile editor is supplied, it can be found in the menu start (All Programs > Hewlett- Packard > HP Automatic Update Server > Profile Editor). The Profile Editor a very basic configuration utility, it is more an XML parser that enables with some (basic) explanation. It is a big contrast with the flashy / well designed / intuitive / user friendly user- interface of the thin clients. DNS/DHCP configuration. To provide the thin clients with the address of the HP Automatic Update Server it is recommended to use DHCP options (instead of a broadcast packet or manual configuration). Since DHCP is required to provide an IP address to the clients this is usually an convenient way of providing the configuration. The address of the HP Automatic Update Server are provided in DHCP option 1. The complete URL needs to be supplied (example : http: //auto- update. If option 1. 37 is not found in the DHCP lease the thin clients tries to resolve the hostname auto- update to an IP address via the DNS server. If a hostname can be resolve the Smart Client will try to retrieve the configuration from this address without the addition of the ‘auto- update’ folder, and will probably fail (4. IIS W3. C logfiles). The client won’t send a broadcast packet! Microsoft DHCP server. The following procedure explains how to do DHCP tagging in a Windows 2. R2 Server. In the left pane, select the Domain to which the thin clients are connected. Right- click IPv. Set Predefined Options. In the Predefined Options and Values dialog box, click Add. In the Option Type dialog box. In the Name field, type auto- update. Select String from the Data type menu. Type 1. 37 in the Code field. Type HP Automatic Update in the Description field. Verify that the information is correct and click OK. In the Value section, type the update server address in the String field. Example: http: //auto- update. Click OK to finish the setup. Source: HP Smart Client Service – Administrators Guide. Linux DHCP server. If your using a linux server as your DHCP server you’re probable using dhcpd (DHCP daemon). You can add the auto- update option with the following lines in dhcpd. Distributing client image / configuration. The most important job of the HP Automatic Update Server is distributing configurations (and maybe new client images). This is all done via the web traffic (HTTP or optionally HTTPS), pulled by the HP Smart Client from the HP Automatic Update Server. The default installation location is %Program. Files%\Hewlett- Packard\HP Smart Client Service\auto- update. This folder contains a number of subfolders Client image. As with any operating system the HP Smart Client is updated to enhance the product with new features and solve issues. Updating the (almost) zero client is very easy by placing the client image on the HP Automatic Update server. If you want all devices to download the same client image the file needs to be placed in %Installdir%\auto- update\Image, if you want a specific device type (like the t. Installdir%\auto- update\< devicetype> \Image. The device will detect the image during the auto- update (usually during boot) and update the operating system.
