这是默认的/etc/ssh/ssh_config,其中包含#ForwardX11 no
,我想更改它,所以我这样做了
augtool set "/files/etc/ssh/ssh_config/ForwardX11" yes
失败了,但这ForwardX11 yes
在Host *
augtool set "/files/etc/ssh/ssh_config/Host/ForwardX11" yes
问题
- 为什么不
augtool
取消注释#ForwardX11 no
? - 为什么我必须指定
.../Host/...
? - 为什么下面的输出中缺少
GSSAPIAuthentication yes
和缺少?ForwardX11Trusted yes
