linux – 尝试SSH到远程计算机但仍要求输入密码

尝试SSH到远程计算机但仍要求输入密码.

我有很多运行SElinux的计算机,其中只有一台在没有密码的情况下使用ssh给我带来了困难.

我做了一个ssh-copy-id,我可以在.ssh / authorized_keys中看到我的密钥.

我chmod 700 .ssh和chmod 600 ./ssh/*中的所有文件

如果我做一个ssh -v这是我的输出:

有人可以告诉我为什么它不能在这台远程计算机上工作?

最佳答案
我经常在CentOS 6机器上遇到类似的bug,涉及ssh-copy-id和SELinux.

当ssh-copy-id创建授权密钥文件时,它使用适当的权限创建它,但使用错误的SELinux标签.解决此问题的方法是使用以下命令将标签恢复为其策略默认值:

restorecon -R~ / .ssh
