TightVNC 2.0 Beta 2

TightVNC 是一款加強版的 VNC 遠端控制軟體，主要解決透過網路操作另一台電腦的需求。它讓您用本地端的滑鼠與鍵盤，連線到指定 IP 的遠端機器，並可隱藏本地游標，避免雙游標干擾。其高效率資料傳輸與 JPG 壓縮，讓中低速網路下也能維持流暢的畫面更新；同時支援「完全控制」與「僅檢視」兩種權限密碼，提升安全性。這套開源工具長期維護，更新頻率穩定，在同類工具中屬於老牌且口碑不錯的選擇，但人氣不如部分商業或整合型軟體。

它適合需要輕量、免安裝的遠端桌面方案的使用者，例如臨時協助親友排除電腦問題，或管理家中或辦公室的數台機器。與 TeamViewer 或 AnyDesk 等商業軟體相比，TightVNC 沒有中繼伺服器，需自行設定網路與防火牆，但換來的是開源與可自訂性。若兩端都安裝 TightVNC，可啟用加強功能；若對方使用其他 VNC Server，也能維持基本連線。目前僅提供英文介面，Windows 平台可下載，使用前需留意語系與設定門檻。

在現今快節奏的數位世界中，遠端存取電腦對 IT 專業人士、企業和個人來說至關重要。

TightVNC 是一款免費且開放原始碼的遠端桌面軟體，讓使用者能透過網路從另一台裝置控制電腦。

VNC Viewer – 透過區域網路或網際網路控制另一台桌上型電腦。

價格

TightVNC 是完全免費的，但企業可以選擇 TightVNC Pro，它提供額外功能和專業支援。

系統需求

• Windows 7、8、10 和 11（32 位元和 64 位元）。
• 需要極少的系統資源。

優點

• 免費且開放原始碼。
• 低資源消耗。
• 支援多重連線。
• 具備檔案傳輸功能。
• 在慢速網路上表現良好。

缺點

• 預設缺乏進階安全功能。
• 沒有官方 macOS 版本。
• 需要網路設定才能進行遠端網際網路存取。

結論

TightVNC 是尋求輕量、免費且開放原始碼遠端桌面解決方案使用者的絕佳選擇。雖然它可能缺乏一些現代安全功能，但它仍然是遠端存取的可靠工具，尤其是在區域網路中。對於需要增強安全性和雲端存取的企業，TeamViewer 或 AnyDesk 等替代方案可能更為合適。

下載 TightVNC 最新版本 為什麼這個應用程式發布在 FileHorse 上？（更多資訊）

* Installer: Valid digital signatures have been added to the installer and installed TightVNC executable files.
* Installer: Featuring new option to add exceptions for TightVNC Server and Viewer to Windows Firewall (supported in Windows XP SP2 or any later version of Windows).
* Installer: Featuring new option to enable system services simulate well-known Ctrl-Alt-Del keyboard combination under Windows Vista and above.
* Installer: The service configuration page (where initial passwords can be set) has become completely optional. And that page will not be auto-selected if the passwords have been set already.
* Installer: An issue with file sharing failure has been fixed - it could be experienced after trying to set both passwords via the service configuration page. Also, there were potential problems with not actually enabling authentication on setting passwords from the installer - they have been fixed as well.
* Installer: There was a number of other minor changes such as user interface enhancements and improvements to the installation logic.
* Server for Windows: Keyboard handling has been fixed. Previous Beta version could handle combinations like Ctrl-C or Ctrl-V incorrectly - it could insert literal C or V instead. New version fixes that - it should interpret keyboard modifiers properly. In addition, it fully supports Windows and Menu keys. Finally, sending Ctrl-Alt-Del remotely should work on all supported versions of Windows.
* Server for Windows: Authentication subsystem has been improved - now it would prevent brute-force attacks on passwords by introducing delays after failed authentication attempts. This works for both RFB connections and for administrative passwords. Another authentication-related fix eliminates erroneous authentication requests on reverse connections.
* Server for Windows: Tight encoder has been fixed - it could work incorrectly in previous Beta version. It did not preserve the state of its data stream in situations when it was disabled and then re-enabled by the viewer. As a result, the viewer could not decode compressed data and had to disconnect. Corrected code accurately preserves the state of each encoder to eliminate such protocol synchronization problems.
* Server for Windows: Clipboard handling has been recovered. Clipboard transfers could fail in either direction due to text format translation problems - resolved now.
* Server for Windows: Mouse position tracking over multiple monitors has been fixed. Previously, coordinates of the mouse cursor could be calculated incorrectly if the primary monitor was not the leftmost and topmost one within a composite desktop.
* Server for Windows: New version sends viewers descriptive error messages if it must close their connections in the very beginning of the session. For example, if the server does not allow "loopback" connections, the viewer will report that fact. Similarly, the viewer should report other errors like protocol version mismatch or rejects caused by repetitive authentication failures.
* Server for Windows: Several useful command-line options have been re-implemented: -connect, -disconnectall, -reload and -shutdown (they must be preceded with either -controlservice or -controlapp in the command line). Similar options (with slightly different names) were supported by TightVNC 1.x, but there were no counterparts available in TightVNC 2.0 Beta 1.
* Server for Windows: Compatibility with other software has been improved. In particular, palette-based pixel formats are now properly supported. TightVNC Viewer never requests indexed colors, but other RFB-compliant software may do that. Previous version of the TightVNC Server could calculate palette colors incorrectly, effectively converting all colors to black. That issue has been resolved.
* Server for Windows: In TightVNC file transfer protocol, file modification timestamps are represented in milliseconds. However, previous version erroneously decreased precision and actually operated with pure seconds. That has been fixed.
* Server for Windows: There was a number of other improvements, including architectural adjustments, additional logging, fixes for real and potential memory leaks, code cleanups, and so on.
* Viewer for Windows: A bug with registering .vnc file extension has been fixed. The viewer wrote incorrect command line to the registry and then could not restore connections saved in .vnc files.
* Viewer for Windows: Keyboard handling has been improved. New version is able to send Windows and Menu keys over the RFB protocol.
* Viewer for Windows: File modification time format has been corrected in file transfer panels. Timestamps were formatted in UTC for some reason, but now they should show up in local time zone.
* Viewer for Windows: "Local cursor shape" setting has been recovered. Now it should take immediate effect on pressing the Ok button in the Connection Options window. In addition, pressing that Ok button would not hide remote cursor - that was another bug fixed in this version.
* Viewer for Windows: TightVNC Viewer could write repetitive entries to the connection history and it could create meaningless directories in the registry when parsing its command line.
* Other minor improvements and fixes have been made.
