VNC Mac和Linux连接被计算机拒绝

Question

我在MacOS X和Linux之间使用VNC有问题。

我在Linux上安装了CentOS服务器，在Mac上安装了vncviewer。我已经完成了所有的设置，然后在Linux计算机上启动vncserver。我还打开了5901港口。

当我在Linux机器上执行命令"vncviewer :1“时，一切正常。我可以看到桌面出现在窗口中。

从Mac，我无法连接到Linux vncserver。我得到的消息是“连接被计算机拒绝”

我能够SSH从Mac到Linux，所以这两台计算机之间有连接，但VNC不能工作。

有人能帮我解决这个问题吗。我搜索了网络，但至今没有发现任何有用的东西。谢谢!

您可以使用本地端口转发通过SSH隧道VNC连接。

要向前启动港口：

ssh -NTf -L 5901:localhost:5901 user@linux_server

然后将VNC查看器指向localhost。

vncviewer localhost:5901
