当 ControlMaster 设置为自动时,ssh X 转发在 LAN 外部的计算机上不起作用

ssh -X我可以使用或ssh -Y和 X 转发工作连接到本地 LAN 上的计算机。但是,当尝试连接到 LAN 之外的计算机时,X 转发失败。

我已将问题范围缩小到文件中的这些行~/.ssh/config

##  Enable auto completion even when needing a password
## as long as one connnection to the server has been established.
Host *
  ControlPath ~/.ssh/master-%r@%h:%p
  ControlMaster auto

这是我的文件包含ssh -vY时的输出~/.ssh/config仅有的上面几行:

$ ssh -vYp 1234 [email protected]
OpenSSH_6.2p2 Debian-6, OpenSSL 1.0.1e 11 Feb 2013
debug1: Reading configuration data /home/terdon/.ssh/config

terdon@server $ echo $DISPLAY

terdon@server $

请注意,没有关于请求 X11 转发的行,与下面的输出相比,显然这些选项覆盖了-Yor-X标志。如果~/.ssh/config文件为空,则上述命令的输出包括(我没有显示整个内容,因为它很长而且我认为无关紧要,如果需要,请告诉我):

debug1: Requesting X11 forwarding with authentication spoofing.
debug1: Sending environment.
debug1: Sending env LANG = en_US.UTF-8

并且X转发成功:

terdon@server $ echo $DISPLAY
localhost:11.0

我试过

Host *
  ControlPath ~/.ssh/master-%r@%h:%p
  ControlMaster auto
  X11Forwarding yes

X11Forwarding yes
Host *
  ControlPath ~/.ssh/master-%r@%h:%p
  ControlMaster auto

但两者都给我这个错误:

Bad configuration option: X11Forwarding

系统信息:

如何允许 X 转发并保留我拥有的配置选项?
