X11 转发一段时间后停止工作

X11 转发一段时间后停止工作

我使用 Cygwin 通过 SSH 连接 Linux 机器(ubuntu server 12.04),并使用 X11 转发。每次我使用 ssh 时,我都可以使用 X 转发一段时间,然后它就会停止工作(例如,gvim 说无法打开显示)。如果我退出并重新使用 ssh,它会再次开始工作。一段时间后又会停止。

有任何想法吗?

当我遇到这个问题时,我发现我需要将这些行添加到~/.ssh/config

Host *
    ForwardX11Trusted yes

您应该将 * 修改为某种主机模式,以便它不会在每个 ssh 连接中启用。

您可能希望更改 ForwardX11Timeout 选项。来自man ssh_config

 ForwardX11Timeout
    Specify a timeout for untrusted X11 forwarding using the format
    described in the TIME FORMATS section of sshd_config(5).  X11
    connections received by ssh(1) after this time will be refused.  The
    default is to disable untrusted X11 forwarding after twenty minutes has
    elapsed.

 ForwardX11Trusted
    If this option is set to “yes”, remote X11 clients will have full
    access to the original X11 display.

    If this option is set to “no”, remote X11 clients will be considered
    untrusted and prevented from stealing or tampering with data belonging
    to trusted X11 clients.  Furthermore, the xauth(1) token used for the
    session will be set to expire after 20 minutes.  Remote clients will
    be refused access after this time.
