ThinLinc 3.3.0 Release Notes

Introduction

A new ThinLinc release is here, 3.3.0. It includes more than 120 enhancements. The most prominent features are:

  • Support for new platforms and desktop environments, such as Mandriva Enterprise Server and Unity 2D.
  • 64-bit versions of all Linux server components.
  • Better performance on high latency networks.
  • Translations to Dutch, French, Russian, and Turkish.
  • Improved functionality in the web administration interface. Many common administration tasks can now be performed with ease.

Changes in This Release

In the list below, the enhancement number is given in parentheses.

Server

  • ThinLinc works on most modern Linux distributions and Sun Solaris (R). This release has been extensively tested on the following platforms:
    • Red Hat (R) Enterprise Linux 6 (64-bit)
    • Mandriva Enterprise Server 5.2 (64-bit)
    • SUSE Linux Enterprise Desktop 11 SP1 (R) (64-bit)
    • Ubuntu (R) 11.10 (64-bit)
    • Sun Solaris (R) 10
  • All server components for Linux are now available as 64-bit versions. This means that a 32-bit environment is no longer necessary to run ThinLinc. The 64-bit X server also provides better performance. 32-bit components are still provided, and the installer automatically selects the appropriate packages. (3241)
  • This release contains the latest technology improvements of the TigerVNC project. In particular, the CPU usage has been lowered both on the client and server side. (3985)
  • ThinLinc is now compatible with Unity 2D, as shipped in Ubuntu 11.10. (4002)
  • The new tool "tl-notify" makes it possible to send notifications to all or selected users in a ThinLinc cluster. (3450)
  • The single sign-on tools can now remove the credentials after use. (3979)
  • A stability problem with "VSM agent" has been corrected. The number of open files increased over time. (3980)
  • Reconnecting to disconnected sessions did not work correctly on the Solaris platform. (3943)
  • Ubuntu 11.10 has a bug which makes the desktop environment consume all CPU if the DPMS extension is not available. As a workaround, ThinLinc now provides this extension. (4029)
  • With ThinLinc 3.2.0, usernames containing dots were not allowed. Such usernames are now allowed again. (4045)
  • The X server in 3.2.0 could crash if the client requested a non-standard compression level. This has been corrected. (3953)

General

  • The graphics performance on high latency links has been improved. For example, this provides a smooth typing experience even if there is a network delay between the client and the server. The improvement is especially noticable in networks with large buffers. Technically, the graphics protocol is no longer limited to one screen update per roundtrip. (2566)
  • Four new translations have been added: Dutch, French, Russian, and Turkish, in addition to the previous translations to German, Spanish, Brazilian Portuguese, and Swedish. (4053)
  • This is the last release which supports legacy clients. Future releases will require client version 2.0.0 or newer, and users need to have a shell that can execute "/usr/bin/thinlinc-login". (3969)

Client

  • Translations are now provided for all parts of the Windows client. (1071)
  • The Mac OS X client is now translated. (2177)
  • Running the client in non-fullscreen mode on Mac OS X should now work better. (4063)
  • The 3.2.0 client contained a bug which caused the client to either crash or lose the mouse cursor, after the cursor shape has been changed many times. This problem has been corrected. (3952)
  • When using the Linux 3.2.0 client with certain window managers, it was not possible to move remote windows by pressing the Alt key and a mouse button. This has been corrected. (3974)
  • The user interface language of the Windows client is now determined by the Windows UI language, instead of the selected locale. (4094)
  • The Client Customizer can now run on Windows 7. Note however that it is necessary to use "Run as Administrator". (3742)
  • A problem related to the clipboard with the Linux client has been corrected. The 3.2.0 client did not copy incoming clipboard data to the PRIMARY selection. This has been corrected. (3948)
  • Printing to a local printer with the Windows client should now be faster and more reliable. This is because the embedded PDF engine "SumatraPDF" has been upgraded. (3933,3956)
  • The Linux client has received improvements to integrate better with the GNOME 3 desktop environment. (3798)
  • The client now requires an i686 CPU (Pentium Pro or compatible). (4008)

Smart Card Support

  • The smart card redirection now works with the AET SafeSign Identity Client. (3951,3984)
  • The smart card redirection is now compatible with OpenSC 0.12.0 and newer. (4022)
  • The OS X client now features smart card redirection. Please note that OS X 10.5.6 or newer is required. (3748)

Administration

  • It is now possible to configure several VSM server and agent settings from the web interface. (3958,3959)
  • The status of VSM server and agent can be monitored, and it is possible to stop and start the services. (1620)
  • ThinLinc profiles can now be managed with the web interface. (3960)
  • The web interface now automatically redirects to HTTPS. (3842)
  • A new "System Health" module has been added to the web interface. It can be used to verify the performance of user and group lookups. (3973)

Windows (R) Integration

  • Windows 7 is now a supported RDP server. (3065)
  • In some cases, the RDP client could fail with "Internal license error" when connecting to Windows Server 2008 R2. This problem has been resolved. (3997)

Frequently Asked Questions

  • ThinLinc is packaged in subscriptions with a tiered pricing system. A higher number of subscriptions will give a lower price. The subscriptions can be purchased for different periods, 12, 36 and 60 month. A longer duration will give a greater price. The payment of the subscriptions is done in advance.

  • Best functionality and performance will always be achieved by upgrading to the latest version, both on the server and client-side. A newer version on the client-side will always give a better user experience than a former version. Cendio’s ambition is to keep good compatibility and functionality between the different versions. Historically, good compatibility between versions has been 3-5 years.

  • A ThinLinc set-up consists of a server software, client software and user licenses.

    Server software

    The server software is the heart of ThinLinc installation and handles all sessions, desktop environments and generates the virtual desktop, workspace etc.

    User licenses

    To allow more than 10 sessions to connect access to the server software, user licenses need to be added into the server software. User licenses are bought from Cendio. Please note, when placing user licenses into the ThinLinc server, the counting starts from 0, not 10. In concrete, this means that you need to buy and install the number of user licenses that you need.

    Client software

    The client software is installed on the device that is used to connect to the server and provision the virtual desktop / workspace. If using the web access client, no local installation of client software is needed, the provisioning is generated via the web browser that is installed at the server.

  • It’s up to the licensee to decide who can connect into the server installation. The ThinLinc client software is free of charge and can be downloaded by everyone.

  • The licensing is per organization. There is no limitation on how the ThinLinc user licenses are distributed in the legal organization, as long as the number of consumed licenses don’t exceed the number of paid licenses. It’s allowed to move the user licenses, but not copy.

  • The license use can be seen in the status module, how to manage can be found at https://www.cendio.com/resources/docs/tag/tlwebadm_status.html#tlwebadm-status . ThinLinc will notify you when the limit of licenses has been reached, for detailed information see, https://www.cendio.com/resources/docs/tag/licensehandling.html?highlight=soft

  • Both the ThinLinc server and client software are free to distribute. The user licenses are connected to a purchase and are not allowed to distribute. For more detailed information, see https://www.cendio.com/thinlinc/docs/legal/eula

  • A specific version of ThinLinc is supported 3 years from release date. After 3 years, Cendio can’t guarantee support.

  • The number of user licenses that will be delivered will be in accordance with the number of subscriptions that have been acquired by the customer. The user licenses are perpetual.

  • When adding user licenses into the ThinLinc server, the counting will start from zero. So if you require 200 users, you need to have 200 user licenses

  • You need to buy user licenses and install them in the ThinLinc server. The user licenses are received through buying ThinLinc subscriptions.

  • It’s easy to add new users into a current ThinLinc set-up. By purchasing additional subscriptions into your agreement, so will we issue additional user licenses.

  • Cendio will, after receiving a valid order, distribute user licenses via email for the latest version after a purchase. If the purchase is a renewal and the customers have already received the latest version, no user licenses will be delivered by default, updated licenses will be delivered on request in this case.

  • It’s possible to merge existing agreements. When doing a merge, the period shall be at least 12 months.

  • The default rule is that the prices are set in accordance with the number of subscriptions that are purchased at the actual call off. Deviation from this can be eventually agreed if a roll-out plan can be committed in advance.
