ProxyJump
是在OpenSSH 7.3中添加的,但仅是使用的简写ProxyCommand
,例如:
Host hidden-host
ProxyCommand ssh proxy-host -W %h:%p
如果您的ssh
版本更高,则可能缺少该-W
选项,在这种情况下,您可以使用nc
,例如:
Host hidden-host
ProxyCommand ssh proxy-host nc %h %p 2> /dev/null
ssh -o ProxyCommand="ssh <proxy-host> -W %h:%p" <target>
而不是ssh -J <proxy-host> <target>
