The TurboVNC Server now uses a bit default visual (BGRX 10/10/10/2 on little endian machines and XRGB 2/10/10/10 on big endian machines) when launched with -depth This is mainly useful for application testing at the moment, since the pixels are downsampled to 8-bit RGB prior to transmission. 32 rows · Download Latest Version TurboVNCxexe ( MB) Get Updates.

The TurboVNC Server, if started with the -nevershared argument, now rejects new connections more gracefully, by sending an RFB authentication failure message to the potential viewer to notify it of the reason behind the rejection. Disabled multithreaded Tight encoding on FreeBSD and similar systems, because the feature segfaults for unknown reasons. This timeout period automatically doubles with each subsequent consecutive VNC password or OTP authentication failure.

If interframe comparison is enabled, the automatic lossless refresh ALR feature in the TurboVNC Server now ignores redundant framebuffer updates framebuffer updates whose contents are completely eliminated by interframe comparison. This prevents ALR from being defeated by ill-behaved applications that continuously render the same image.

To prevent performance degradation on high-latency networks while using the automatic lossless refresh ALR feature, the TurboVNC Server now temporarily increases the ALR timeout to ensure that the timeout is always greater than the network round-trip time measured by the RFB flow control extensions. Introduced a new Java system property turbovnc.

Fixed an issue in the Java TurboVNC Viewer whereby, in listen mode, the full-screen mode setting did not take effect if it was changed in the Default Options dialog. In addition to allowing external SSH issues to be diagnosed more easily, this also allows interactive SSH authentication methods to be used on Windows. Fixed an issue in the Windows TurboVNC Viewer whereby keyboard grabbing was always initially disabled in the second and subsequent connections initiated by the viewer, regardless of the grab mode.

This emulates the behavior of Linux. Fixed an issue whereby, if the physical screens on the client had mismatched resolutions or were offset, the TurboVNC Viewer would not use all of the available screen real estate in full-screen mode with multi-screen spanning enabled. The viewer now properly fills all screens in this case, as long as automatic desktop resizing is enabled and the VNC server supports Xinerama multiple virtual screens , i.

A new security configuration file directive permitted-cipher-suites in the TurboVNC Server and a new Java system property turbovnc.

Fixed an issue in the Mac TurboVNC Viewer whereby drawing tablet stylus buttons were ignored or mapped to incorrect mouse button events. Fixed a packaging regression, introduced by 2.

Fixed a regression introduced by 2. Fixed an error “java. IllegalArgumentException: Error in security property.

Furthermore, since exploiting the issue would have first required successfully authenticating with a TurboVNC session, the issue did not generally provide an attack vector for anyone other than the session owner and any collaborators authorized by the owner.

This fixed an error “dh key too small” that occurred when attempting to connect, using one of those security types, to a TurboVNC session running on a RHEL 8 host. It also fixed an error “javax. A new security configuration file directive tls-key-length can be used to restore the behavior of previous releases of TurboVNC generating a bit DSA key or to increase the key length for additional security.

Fixed an error “javax. Fixed an issue in the TurboVNC Server whereby, if interframe comparison was enabled and the remote desktop was resized to a smaller size, the server would sometimes send a framebuffer update that exceeded the new desktop dimensions.

Fixed a denial-of-service DoS vulnerability in the TurboVNC Server that was exposed when many RFB connections were made to the server and never dropped, thus exceeding the Xvnc process’s allotment of file descriptors. Org code because the incoming RFB connection never succeeded. This infinite loop prevented the TurboVNC session owner from launching any X11 programs in the session since those require Unix domain socket connections until one or more of the RFB connections dropped, and the continuous flood of error messages in the session log caused the log to grow by megabytes per second until all available disk space was exhausted.

The TurboVNC Server now sets a reasonable RFB connection limit which can be adjusted using a new Xvnc argument, -maxconnections and rejects all new connections once this limit has been reached. From the point of view of applications running in the TurboVNC session, the extended input device buttons appeared to stick in the down or up position.

An optimized version of PuTTY 0. Fixed an issue in the vncserver script whereby generating an initial one-time password OTP would fail if X11 TCP connections were disabled which is now the default, because of 2. The script now defers setting the default locations of those files until after turbovncserver. The vncserver script now allows VirtualGL to be enabled using the turbovncserver. The vncserver script now allows the window manager startup script to be specified using a new command-line option -wm or turbovncserver.

Introduced a new turbovncserver. This allows any TurboVNC Server option to be enabled or disabled on a system-wide or per-user basis, even if that option has no corresponding turbovncserver.

Fixed a segfault in the TurboVNC Server that occurred, under rare circumstances, when a viewer disconnected. Previously, it was sending an Alt key press and a Ctrl key release. This was a regression caused by a bug in the xorg-xserver 1. The default xstartup. Unity 3D 5. The -list option for the vncserver script no longer lists orphaned TurboVNC sessions sessions for which a PID file exists in the user’s VNC directory but for which the corresponding Xvnc process is no longer running.

Fixed an issue in the vncviewer-javaw. Passing -extension GLX to vncserver disables the extension. Note that your system must have Mesa 8. On systems that do not have vendor-specific GPU drivers installed, or on systems that provide a libglvnd-enabled build of Mesa, the TurboVNC Server’s GLX extension will use direct rendering, which improves performance and compatibility.

Java SE 6 ceased receiving public updates in and, as of this writing, critical bug fixes and security fixes for that platform are only available with an Oracle Extended Support contract. The 2. Most popular web browsers have already abandoned the NPAPI plugin standard around which the Java plugin was designed, because that plugin standard grants full access to the client machine.

However, such access is necessary in order to write a full-featured application including a VNC viewer , and absent any other cross-browser plugin standard, it would be impossible for Oracle to make the Java plugin more secure without abandoning the write-once-run-anywhere nature of the Java language. Thus, they have chosen not to include any kind of browser plugin in Java 9.

As of this writing, NPAPI support can only be obtained on most platforms by installing an older browser version. The only advantage of using the TurboVNC Viewer as an applet, as opposed to with Java Web Start, was the ability to embed the viewer in a web page, but this mode of operation had some known usability issues and was increasingly receiving little or no attention from the TurboVNC community.

The applet feature will continue to be supported in TurboVNC 2. The TurboVNC Server now has full support for the Xinerama extension, which allows multiple virtual screens to be configured within the same remote desktop. This provides better usability for multi-screen environments, since dialogs and maximized application windows are no longer split across screen boundaries.

The server’s screen layout can be configured in the following ways:. The automatic desktop resize feature in the TurboVNC Viewer is now multi-screen aware in both windowed and full-screen modes. The single-screen automatic desktop resizing behavior of the TurboVNC 2. The X RandR extension can be used, either from the command line xrandr or through the window manager’s display configuration applet, to modify the server’s screen layout.

This mimics the behavior of most modern X servers, which require X11 connections to be made using Unix domain sockets. The xstartup. The -3dwm option for the vncserver script has been renamed to -vgl , to reflect the fact that the TurboVNC Server is now able to run 3D window managers without using VirtualGL. Clipboard synchronization is now performed within the TurboVNC Server process, so the tvncconfig utility is no longer needed or provided. This is mainly useful for application testing at the moment, since the pixels are downsampled to 8-bit RGB prior to transmission.

This will probably fail unless the system is using xorg-server 1. This system is normally used to input language-specific characters in Asian languages, but since the TurboVNC Viewer does not handle those characters, the IME does nothing but interfere with the normal operation of the viewer. Introduced a new security configuration file directive no-remote-resize that can be used to disable remote desktop resizing on a system-wide basis. Because of 2.

This is useful when connecting from clients that have “natural scrolling” enabled. Fixed an issue in the Mac Java TurboVNC Viewer whereby the initial non-full-screen window was positioned incorrectly if it spanned multiple screens. Fixed an issue in the Windows native TurboVNC Viewer whereby multi-screen spanning did not work at all if the secondary display was to the left of the primary display. The TurboVNC Server will now clamp the desktop dimensions to x regardless of the max-desktop-size setting in the security configuration file.

This prevents two issues:. Closed a loophole that allowed users to use X RandR functions to make the desktop larger than the dimensions allowed by the max-desktop-size setting in the security configuration file.

When automatic desktop resizing and automatic spanning are both enabled, the TurboVNC Viewer will now use single-screen spanning “Primary monitor only” when in windowed mode and multi-screen spanning “All monitors” when in full-screen mode. It is still necessary to set ApplePressAndHoldEnabled to false, either in the global domain or the com. Fixed an issue that prevented the keyboard grabbing feature from working properly in the Java TurboVNC Viewer on bit Windows systems.

Fixed an issue whereby, when server-side cursor rendering was enabled, the cursor would flicker on and off as the mouse was dragged. This facilitates using a different window manager for local and remote desktop sessions on the same machine, or temporarily switching the window manager used by TurboVNC.

Fixed a bug in the X. Fixed a couple of issues in the TurboVNC Server that prevented cursors from being rendered and transmitted properly if the server was running on a big endian system. Fixed an issue in the Windows TurboVNC Viewer whereby, if keyboard grabbing was disabled, using Alt-Tab to select another window would sometimes leave the Alt key in a pressed state on the server.

Fixed an issue in the Java TurboVNC Viewer whereby the client clipboard contents would not be transferred to the server if text was selected in the VNC session and the middle mouse button was clicked in the viewer window without first bringing the window to the foreground. Worked around an issue in OS X whereby the TurboVNC Viewer window would not be brought to the foreground if a mouse button other than the primary button was clicked in it.

Because OS X sends only mouse press events to non-foreground windows, this issue was causing mouse buttons other than the primary button to become stuck in the pressed state on the server if one of those buttons was clicked in the viewer window while the window was in the background. Fixed an issue in the TurboVNC Server whereby it would hang and eventually time out when attempting to negotiate VeNCrypt capabilities with the viewer.

This issue was known to affect only Solaris 11 hosts, but it might have also affected other platforms under rare circumstances. Worked around another issue in Java that caused AltGr symbols associated with a dead key for instance, the ‘ ‘ symbol on Danish keyboards to be transmitted incorrectly. The init. The default behavior of the TurboVNC Server is to refuse new non-shared connections if a viewer is already connected.

Previously, the server accomplished this by hard-coding the -dontdisconnect argument to Xvnc inside of the vncserver wrapper script. This release of TurboVNC instead makes -dontdisconnect the default in Xvnc and introduces a new Xvnc argument -disconnect to reverse the behavior. This new option allows TurboVNC to mimic the behavior of other VNC implementations that disconnect existing viewers when a new non-shared connection is established.

Added a new parameter to the Java TurboVNC Viewer LocalCursor that, when enabled, causes cursor shape updates to be ignored and the local cursor to always be displayed. This option is useful when connecting to broken VNC server implementations that do not properly support server-side cursor rendering or cursor shape updates.

This was known to affect certain Qt5 applications running under Debian Stretch but may have also affected other applications and platforms.
