Question

我是unix / linux的新手，在尝试将隧道连接到我大学的计算机时遇到了一个问题。

我试图访问我学校网络上的计算机A.但除非我已经在学校网络上，否则无法访问它。我可以ssh到计算机B然后ssh到计算机A.让我们说计算机C只能通过计算机B访问，我如何制作一个可以为我做这个的shell脚本？

到目前为止，我通过B隧道进入计算机A，但无法进入C. 我试过这个

    ssh -t user@computerB 'ssh user@computerA' 'ssh user@computerC'
    sh -t user@computerB "ssh user@computerA 'ssh user@computerC'"

我做错了什么

Answer 1

似乎对我有用。显然你必须使用-t来强制每次跳转的ptty分配：

jcomeau@intrepid:~/rentacoder/peppe/dentalcam$ ssh -t www "ssh -t tek 'ssh -t www'"
