SSH Permission denied (publickey

1. 登陆时报错

[root@nebula-api .ssh]# ssh -i .ssh/id.key -p 22 user@host.com
user@host.com's password:
Authenticated with partial success.
Permission denied (publickey).

2. 找了2个小时没有找到方法, 加上调试参数也看不错问题

-vvv

3. 在服务器端查看日志，

Mar 19 09:02:27 usloftxxx sshd[2621]: Accepted password for user from 192.168.0.100 port 28907 ssh2
Mar 19 09:02:27 usloftxxx sshd[2622]: Connection closed by 192.168.0.100

4. 上面的错误信息也看不出问题
5. 尝试一些重启 sshd

[root@usloftxxx .ssh]# service sshd restart
Stopping sshd:                                             [  OK  ]
Starting sshd:                                             [  OK  ]

6. 查看日志

tail -f  /var/log/secure
Mar 19 09:02:24 usloftxxx sshd[2621]: Authentication refused: bad ownership or modes for directory /home/user

7. 最终找到问题，是home目录的权限被其他人修改了 .......

[user@usloft3594 ~]$ ll -d ~
drwxrwx--- 12 user user 4096 Mar 19 17:00 /home/user

8. 修正用户权限后即可解决问题

chmod 700 ~
