Question

当我尝试ssh到localhost时，它接受公钥并立即关闭连接。我已经浏览了几个小时的谷歌搜索结果，但没有任何进展。这是我在ssh -v user@localhost后得到的：

我正在运行OSX 10.8，通过终端使用ssh。

Answer 1

好的，最终工作的是明确允许来自user的连接。将System Prefs > Sharing > Remote Login > Allow access for:设置为All Users不起作用;相反，我必须检查Only these users:并手动添加所有用户。希望这有助于其他人遇到同样的问题。

Answer 2

很久以前我遇到了与Telnet相同的问题，如果我记得很清楚，问题在于用户在/ etc / passwd中没有主目录。我假设您正在尝试创建无密码连接，我是对的吗？当你google它时，这里有一个很好的解释：http://diuf.unifr.ch/main/tech/node/57 另外，这里有一个解释如何快速使密码更少连接http://greg-n-blog.blogspot.com/search/label/scp

这在Cygwin中使用Windows在大域中起作用了：

将您的Windows用户ID添加到/etc/passwd。您可以输入$ mkpasswd -d | grep [username]来获取它。在大型域中，您可能需要等待几个小时。

确保/etc/passwd中提供的用户ID与$ id -u中的用户ID相匹配，并且组ID与/etc/group中的管理员ID相匹配

SSH：localhost在成功登录后关闭连接
