ubuntu – 无密码SSH无法正常工作 – 密钥已复制并设置了权限

前端之家收集整理的这篇文章主要介绍了ubuntu – 无密码SSH无法正常工作 – 密钥已复制并设置了权限前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
我知道这个问题已被提出,但我确信我已经完成了所有其他答案的建议.

机器A:

>使用keygen -t rsa在〜/ .ssh /中创建id_rsa.pub
>将计算机A的id_rsa.pub复制到计算机B用户的主目录
>制作id_rsa.pub 600的文件权限

机器B.

>将机器A的pub键添加到authorised_keys和authorised_keys2:cat~ / id_rsa.pub>>的〜/ .ssh / authorised_keys2
>制作了id_rsa.pub 600的文件权限

我还确保两个.ssh目录在机器A和B上都具有权限700.

如果我尝试从机器A登录到机器B,我会被要求输入密码,而不是ssh密码短语.

我让两台机器上的root用户使用无密码ssh互相交谈,但我无法让普通用户这样做.

双方的用户名是否必须相同?还是有一些我错过的设置.

机器A是在@L_301_0@ 7 PC上的VirtualBox内运行的Ubuntu 10.04虚拟机,机器B是专用的Ubuntu 9.10服务器

更新:我使用选项-vvv运行ssh,它提供了许多输出行,但这是最后几个命令:

debug3: check_host_in_hostfile: filename /home/pete/.ssh/known_hosts

使用ssh-copy-id复制密钥;它将创建任何必要的文件/目录并修复任何破坏的权限.
