我可以ssh
加工 xyz:
$ ssh xyz
mitchus@xyz's password:
Last login: Fri Sep 1 12:37:10 2017 from 192.168.1.23
mitchus@xyz:~$
但我无法scp
执行此操作,也无法通过发送命令ssh
。例如,ssh xyz echo hello
卡住了。
我准备好了检查交互式会话在我的服务器用户.bashrc
脚本中,也尝试修改/etc/ssh/sshd_config
以使用
UsePAM no
但这并没有改变任何东西。如果相关的话,我正在尝试从 MacOS 10.11 连接到 Ubuntu 16.04 盒子,两者都在同一个 wifi 网络上。
以下是输出ssh -vvv xyz echo hello

lost connection
答案1

,该选项强制创建虚拟 TTY 设备,但很难让 scp 工作,该 scp 使用 ssh 在远程系统之间复制文件。
要强制为 scp 创建虚拟 TTY 设备,需要使用-o
参数,后跟以与 ssh 配置文件相同格式编写的 ssh 选项列表,因此在本例中-o RequestTTY=force
.
