VNC“No configured security type is supported by 3.3 viewer“的解决办法！

VNC“No configured security type is supported by 3.3 viewer“的解决办法！

用移动设备连接PC的VNC服务器端时，总会出现这种奇怪的现象，用ultraVNC做服务期端的话，可以非常容易地从移动设备连接到PC端。可是用realVNC的话，缺总会出现No configured security type is supported by 3.3 viewer这样的错误提示，甚是奇怪，可是realVNC如此大牌的VNC软件必须解决这个问题啊，要不然多郁闷啊。

在网上查呀查，终于找到了一篇老外发的帖子，看来老外也遇到过这种问题。帖子内容如下：

I have RealVNC Enterprise installed on RedHat Linux 9. When I try to connect

to the linux box with VNC clients I get the following error:

Noconfiguredsecuritytypeissupportedby 3.3 viewer.

I understand from postings in this list that the encryption being used by

RealVNC Enterprise server is incompatible with these viewers. However, I see

no instructions for changing the authentication method to just password

authentication. I need that because some people who need to VNC into this

server will not want to purchase a RealVNC license. Is there a shell command I

can use to tell RealVNC that I want simple password authentication?

Jim,

If you set your server to use VNC Authentication and the server's Encryption

setting to Prefer On in order for RFB 3.3 clients to be able to connect.

Alternatively, since the server is licensed, you can just use VNC Enterprise

Edition viewers to connect to it.

Wez @ RealVNC Ltd.

其实最重要的就一句话，setting to Prefer On in order for RFB 3.3 clients to be able to connect.

意思就是，把realVNC的encryption选项选为prefer on即可。

so easy!让我折腾了这么旧
