ThinLinc

ThinLinc is a commercial terminal server system that is fast and versatile.

The ThinLinc server software runs on Linux or Solaris by default, but it can also be used to distribute Linux/UNIX desktops to thin clients.

What is new in this release:

• Server:
• ThinLinc works on most modern Linux distributions and Oracle Solaris (R). We recommend that you deploy ThinLinc on one of these tested platforms:
• Red Hat (R) Enterprise Linux Server 6 (64-bit)
• SUSE Linux Enterprise Desktop 11 SP3 (R) (64-bit)
• Ubuntu Desktop (R) 12.04 (64-bit)
• Oracle Solaris (R) 10

• It is now possible to send special keys such as Escape, Tab, Control, Alt from touch devices. (4759)
• Dynamic resize support has been added to the HTML5 client. The remote session will automatically resize when the size of the local browser window changes, the tablet is rotated etc. (4642)
• It should now be easier to "double click" when using the HTML5 client on touch devices. (4666)
• The previous release of the web access service failed to verify if an account was expired. This has been corrected. (4829)
• Smart Card Support:
• Multiple issues with the PC/SC Smart Card redirection has been fixed. The redirection should now work with the second generation Novell Client, used on Vista and newer systems. (4511, 4740, 4741, 4742, 4746)
• Local Drive Redirection:
• Copying files between a server and a 64-bit client failed with an error in earlier versions, this has been corrected. (4592)
• Administration:

• SeamlessRDP now works better with with "topmost" windows. (4807)

What is new in version 4.1.0:

• Server:
• ThinLinc works on most modern Linux distributions and Oracle Solaris (R). We recommend that you deploy ThinLinc on one of these tested platforms:
• Red Hat (R) Enterprise Linux Server 6 (64-bit)
• SUSE Linux Enterprise Desktop 11 SP2 (R) (64-bit)
• Ubuntu Desktop (R) 12.04 (64-bit)
• Oracle Solaris (R) 10
• The X Server platform has been upgraded. The X server is now based on X.Org 1.14.0. In addition to support for new extensions such as XInput2, it is also faster. The "render_bench" test indicates a performance increase of 30%. Compatibility with Unity 2D has also been improved. The "RandR" interface has been upgraded from version 1.2 to 1.4. (4417)
• ThinLinc now works with "GNOME Shell" - the core user interface of GNOME 3. (3836, 4598)
• The X Server now provides the X keyboard extension (XKB). This gives better compatibility with modern applications and desktop environments. This extension also provides a more advanced interface for keyboard handling. (3074)
• GLX version 1.4 is supported. This is the latest version of the OpenGL extension to the X Window System. (4019)
• A session profile for the MATE Desktop is provided. (4406)
• A problem with the earlier release could cause the login services to stop responding every sunday, when installed on Ubuntu distributions. This has been corrected. (4471)
• The symbolic link ~/.thinlinc/xinit.log is no longer created. The session log is instead available as /var/opt/thinlinc/sessions/$USER/last/xinit.log . (3780)
• The default keyboard layout is now "US". Please note that the "-KeyboardMap" argument is no longer supported. The default layout is defined by the /sessionstart/keyboard_layout parameter. It can also be changed at runtime with the "setxkbmap" command. Also note that the default layout of a remote RDP session is determined by the locale of the user session. (4526)
• Several versions of Ubuntu contains a LSB support script "install_initd" which does not work. This release contains a workaround for this problem, allowing the ThinLinc services to be installed correctly on these distributions. (4546)
• On some systems with the "AppArmor" security module, applications such as Evince did not start. This has been corrected. (4468)
• It is now possible to configure OpenSSH on a ThinLinc Server with a restricted port forwarding configuration, where a user can only create port forwards to their own Xvnc instances. This feature uses the "PermitOpen" option and is available with OpenSSH 4.5 and later. (4591)
• In earlier versions, the xfig application was not displayed correctly when using 64-bit ThinLinc servers. This has been corrected. (4539)
• General:
• This release features support for publishing a single application. This mode is activated by calling the application with the tl-single-app command, either from the client, or by creating a suitable profile on the server. (4465, 4466)
• Client:
• The ThinLinc client now supports authentication using an existing Kerberos ticket. In a Kerberos environment, this makes it possible to initiate ThinLinc connections without having to enter credentials. (4003)
• The Windows client is now supported on Windows 8 and Windows Server 2012. (4353)
• A HTML5 client is included as a "Technology Preview" feature, called "ThinLinc Web Access". This client makes it possible to connect to ThinLinc servers from devices which lacks a native client, including the Apple iPad. (4132)
• The Windows client now uses "OpenSSH" SSH client. This means that the SSH implementation is now the same on all platforms. This also means that the file format of public key identify files has been changed: The Windows client now requires OpenSSH identify files. (3183)
• A client package for "Wyse Enhanced SUSE Linux Enterprise Thin client" (SLETC) is now provided. (3725)
• A client package for "Wyse Linux v6" is no longer provided. (4503)
• The client is more tolerant against user profile scripts (.tcshrc, .bashrc etc) which prints information during login. (4540)
• A problem with comma/delete on the numeric keyboard has been corrected. (4068)
• Smart Card Support:
• Smart Card Single Sign-On against Windows 2008 and Windows 2008 R2 is now supported. (3393)
• When authenticating with a smart card, the client will now forward information about the used card, certificate and smart card reader to the server. This information can be used by the RDP client when authenticating with a smart card against Windows servers, providing a single sign-on experience. (4498, 4565)
• Printing Support:
• Printing to the "local" printer with the Windows client did not work if the option "Show printer selection dialog on each print" was active. This has been fixed. (4625)
• Virtual Desktop Infrastructure (VDI):
• The VirtualBox integration has been removed. (4486)
• TLCOS:
• Please note that this is the last release which includes TLCOS. Various other alternatives are available. This includes Thinstation, eLux from Unicon Software, and Universal Desktop Converter from IGEL Technology. (4356)
• Windows Integration:
• The RDP client now supports Credential Security Support Provider (CredSSP). (2571)
• The RDP client can automatically reconnect to the server after a network failure. (4501)
• SeamlessRDP supports "session sharing". This means that multiple applications can be invoked in seamless mode, using a single remote RDP session. This minimizes resources and reduces the time it takes to start an additional application. (2289)
• SeamlessRDP did not work against Windows 2008 R2. This has been corrected. (4517)
• Corrected Issues:
• ThinLinc has also been enhanced in many other ways. The complete list of corrected issues is:

What is new in version 4.0.0:

• Server:
• ThinLinc works on most modern Linux distributions and Oracle Solaris (R). We recommend that you deploy ThinLinc on one of these tested platforms:
• Red Hat (R) Enterprise Linux Server 6 (64-bit)
• SUSE Linux Enterprise Desktop 11 SP2 (R) (64-bit)
• Ubuntu Desktop (R) 12.04 (64-bit)
• Sun Solaris (R) 10
• The installation program has been updated with several bug fixes to increase compatibility. (4360, 4442, 4446)
• The startup scripts will now fetch a Kerberos ticket for the session by default. (4301)
• The notifications for session shadowing has been made more robust against false warnings. (4321)
• General:
• The client and the server now both fully support multiple monitors. This includes both making sure the session covers all monitors, as well as exporting monitor dimensions to the server for correct window placement inside the ThinLinc session. (14, 2426, 3094, 4229)
• Client:
• A 64-bit version of the Linux client is now available. (3230)
• Compatibility with Mac OS X 10.8 has been improved. (4366, 4368)
• Client window placement has been improved in multi monitor environments. It should now avoid crossing monitor edges, and the session will always be displayed on the same monitor as the login window. (3892, 4275)
• Sessions are now dynamically resized as the local client window is resized. Previously a reconnect was required to resize the session. (3673)
• A performance issue on AMD Bobcat CPUs has been identified and fixed. These CPUs are found in several recent terminals. (4328)
• The installation programs for the Windows client are now signed, increasing security on that platform. (2075)

• Support for Thinstation has been updated from version 2 to version 5. (4318, 4349)
• Windows 2000 is no longer a supported platform for the client. Users are encouraged to upgrade to a later version of Windows. (4367)
• The client now better supports systems that have case sensitive user names. Previously, the client always converted the user name to lowercase. This is now optional, and the default is not to alter the name. Please note: this means that in some configurations, the user name field in the earlier client was perceived as case insensitive, while the new version will require correct case. (2197)
• Edge scrolling, also known as bump scrolling, has been restored when the client is in full screen mode. This feature was lost in ThinLinc 3.2.0. (4343)
• Smart Card Support:
• The bundled OpenSC library has been upgraded, increasing compatibility with modern cards. (4377)
• The Linux client will no longer ask for a PIN even if the server rejects the certificate. (2991)
• Audio Redirection:
• The embedded PulseAudio server, which is used for audio redirection, has received a major upgrade. This will increase compatibility with modern desktop environments and applications. (2505, 3222, 3227, 4346)
• Windows (R) Integration:
• The RDP client now supports Transport Layer Security (TLS) 1.0. TLS is the latest version of the Secure Sockets Layer (SSL) protocol. (4347)
• SeamlessRDP should now be better at ignoring command line windows (which cannot be properly exported seamlessly). (2369)
• SeamlessRDP is now better at determining when a session should be terminated. (4007)
