Question

我在机器A上有一对epadmin的密钥。我通过文件夹中的scp将它们复制到epadmin主文件夹中的机器B上.ssh

访问命令：ssh epadmin@10.2.11.13

[epadmin@3A1D .ssh]$ ls -la
total 24
drwxrwxr-x 2 epadmin epadmin 4096 May 12 14:41 .
drwx------ 6 epadmin epadmin 4096 May 12 14:40 ..
-rw-r--r-- 1 epadmin epadmin  438 May 12 14:41 config
-rw------- 1 epadmin epadmin 1671 May 12 14:41 id_rsa_auto_epmc
-rw-r--r-- 1 epadmin epadmin  407 May 12 14:41 id_rsa_auto_epmc.pub
-rw-r--r-- 1 epadmin epadmin 2818 May 12 14:41 known_hosts

这是一段-vvv（详细）日志

我无法在没有密码的情况下登录

一块sshd_config。我试图取消注释RSAAut并将no粘贴到密码auth。没有变化

# Authentication:
#RSAAuthentication yes
#PubkeyAuthentication yes
#AuthorizedKeysFile     .ssh/authorized_keys
#AuthorizedKeysCommand none
#AuthorizedKeysCommandRunAs nobody

# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
#RhostsRSAAuthentication no
# similar for protocol version 2
#HostbasedAuthentication no
# Change to yes if you don't trust ~/.ssh/known_hosts for
# RhostsRSAAuthentication and HostbasedAuthentication
#IgnoreUserKnownHosts no
# Don't read the user's ~/.rhosts and ~/.shosts files
# To disable tunneled clear text passwords, change to no here!
#PasswordAuthentication yes
#PermitEmptyPasswords no
PasswordAuthentication yes

# Change to no to disable s/key passwords
#ChallengeResponseAuthentication yes
ChallengeResponseAuthentication no

Answer 1

您的问题应该是服务器故障。这是一个基本的麻烦，或者我应该说两个：

：当您在.ssh目录中的epadmin上传密钥时，必须在authorized_keys中重命名id_rsa_auto_epmc.pub文件
：您使用私钥的非默认密钥名称，因此您必须使用-i选项指定密钥的路径：ssh -i~ / id_rsa_auto_epmc

默认sshd_config文件不需要进行任何更改以进行密钥验证。对于您的问题，最好放置您使用的ssh命令行。

xx - ip host

Answer 3

①你的目录.ssh应该是0700而.ssh dir和他儿子的文件的作者和团体是你的

②authorified_keys应为0600或0644

③你可以将公共authorkey内容复制到authorized_keys不运行，现在你可以尝试将authorkey复制到远程主机你的dir .ssh并重命名authorized_keys，是的，你可以尝试一下！我的英语水平很差

ssh连接权限被拒绝（publickey，gssapi-keyex，gssapi-with-mic，密码）
