我需要從另一臺Ubuntu PC和Windows PC進行遠程連接到一臺Ubuntu PC（需要看UI）。我知道我們可以使用VNC來做到這一點。任何人都可以用這些步驟解釋我，或給出一個正確的鏈接，其中有指示。使用vnc連接ubuntu
我按照以下步驟操作： 在我需要遠程訪問的Ubuntu機器上安裝vnc服務器。 我跟着下面的鏈接
http://www.ubuntu-unleashed.com/2007/10/setup-vnc-server-for-ubuntu-gutsy.html
當我做了第4步中的說明：
x11vnc -forever -usepw -httpdir /usr/share/vnc-java/ -httpport 5800
我得到

20/12/2012 02:12:02 passing arg to libvncserver: 5801
