個人嘗試使用win10 + debian子系統(tǒng)安裝運行Apache Guacamole實現(xiàn)web端遠程連接服務器。

在安裝完成后，可以正常連接華為云服務器（window Server2008），在遠程本地win10時報錯。

web端面頁面提示如下

The remote desktop server is currently unreachable. If the problem persists, please notify your system administrator, or check your system logs. ?

guacamole-client Tomcat報錯如下

經過查找相關解決方案（適用于Windows Server 2016 RDP），需要修改win10注冊表。內容如下

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp] 修改“SecurityLayer” 項的值為 1 修改 “UserAuthentication” 項的值為 0

做個記錄..
