VNC 官方網站：http://www.realvnc.com
步驟:
安裝vnc (//Fedora發行版巳包含了VNC軟體)
=>apt-get install vnc-server
啟動vnc server (初次啟動server會要求密碼，啟動後會在各user家目錄下產生.vnc資料夾)
=>vncserver //vncserver跟/etc/rc.d/init.d/vncserver似乎不一樣
修改畫面設定檔
=>vi ~/.vnc/xstartup 取消此兩行前面的 #
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
p.s Fedora發行版巳包含了VNC軟體，不過預設使用TWM視窗管理程式，可以修改為GNOME如下:
mkdir /etc/vnc/
用文書編輯軟體開啟 /etc/vnc/xstartup 輸入一行 exec /etc/X11/xinit/Xclients 後存檔離開
chmod+x /etc/vnc/xstartup
修改帳號設定檔
=>vi /etc/sysconfig/vncservers
# VNCSERVERS="1:myusername" 修改成-->VNCSERVERS="1:root"
# VNCSERVERARGS[1]="-geometry 800x600"
重新啟動
/etc/rc.d/init.d/vncserver restart
開放port
VNC使用兩個port，請記得開放，5801:tcp,5901:tcp
測試
使用網頁瀏覽器遠端遙控 Fedora：http://IP:5801
註：
因為使用瀏覽器連上 vncserver 的時候會執行 java applet，所以 client 端一定要先安裝 java 相關軟體才行
