ssh:权限被拒绝(公钥，键盘交互) [英] ssh: Permission denied (publickey,keyboard-interactive)

问题描述

我使用的是 linux 系统我在本地目录上创建了一个 ssh 密钥$ ssh-keygen -t rsa -f ~/.ssh/id_rsa

I'm using linux system I created a ssh key on local directory $ ssh-keygen -t rsa -f ~/.ssh/id_rsa

然后将公钥上传到planetLab系统

and then uploaded the public key to planetLab system

然后我尝试使用以下命令登录 PlanetLab 节点:ssh -v
调试信息如下:

then I tried to log in a PlanetLab node using: ssh -v
the debug information is as follows:

如何处理这个问题?谢谢！

how to deal with this problem? thanks!

我注意到一个问题，以前，我们组是 tika现在改为uslin但是，即使我删除了以前的键并使用ssh-keygen 生成新的密钥，组仍然如下:

I notice a problem, previously, our group is tika now it is changed to uslin however, even if I deleted the previous keys and use ssh-keygen to generate new keys, the group is still as below:

-rw------- 1 wgong tika 1766 Mar  6 19:06 id_rsa
-rw-r--r-- 1 wgong tika  394 Mar  6 19:06 id_rsa.pub
-rw-r--r-- 1 wgong uslin   3987 Mar  6 18:11 known_hosts

这是问题吗?如何解决?谢谢！

is this the problem? how to fix it? thanks!

推荐答案

确保服务器上的 ~/.ssh/authorized_keys 文件包含您的公钥.另外，请检查此文件的权限 - 如果权限太松，您将无法登录:

Make sure your ~/.ssh/authorized_keys file on the server contains your publik key. Also, check this file's permissions - if permissions are too lax, you won't be able to log in:

chmod 600 ~/.ssh/authorized_keys
chmod 700 ~/.ssh/
chmod 700 ~

是的，即使您的主目录权限也可能导致无法使用密钥登录.

Yes, even your home directory's permissions may make logging in with the key impossible.
