非交互式 ssh 登录后立即断开连接

  • 772

我正在尝试通过 Linux 机器上的 ssh 从诺基亚路由器获取一些信息。

如果我这样做，ssh 可以正常工作：

ssh [email protected]

我可以输入密码，登录，运行命令。

但是，当我执行以下操作时，它会立即断开我的连接：

ssh -v [email protected] 'show time'

Verbose output:
debug1: Next authentication method: password
[email protected]'s password: 
debug1: Authentication succeeded (password).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.
debug1: Sending environment.
debug1: Sending env LC_PAPER = en_US.UTF-8
debug1: Sending env LC_ADDRESS = en_US.UTF-8
debug1: Sending env LC_MONETARY = en_US.UTF-8
debug1: Sending env LC_NUMERIC = en_US.UTF-8
debug1: Sending env LC_TELEPHONE = en_US.UTF-8
debug1: Sending env LC_IDENTIFICATION = en_US.UTF-8
debug1: Sending env LANG = en_US.UTF-8
debug1: Sending env LC_MEASUREMENT = en_US.UTF-8
debug1: Sending env LC_TIME = en_US.UTF-8
debug1: Sending env LC_NAME = en_US.UTF-8
debug1: Sending command: show time
debug1: channel 0: free: client-session, nchannels 1
Connection to 10.0.0.1 closed by remote host.
Transferred: sent 2088, received 1840 bytes, in 0.0 seconds
Bytes per second: sent 488193.7, received 430209.0
debug1: Exit status -1

如果我使用期望脚本连接，发送密码，然后发送命令，它工作正常。

有什么问题？

    感谢所有的评论。

    最后，我最终使用了 expect，因为我正在使用 bash 脚本来连接和提取信息。
