如题。目前的基本情况是:
本地:
OS:OS X 10.11.6
用户名:fourstring
服务器:
OS:Ubuntu14.04 x64 LTS
用户名:git(想要建立git远程仓库)
我新建了git用户,然后在/home/git
下建立.ssh
目录,设置权限为git:git 0700
,并在.ssh
目录下运行ssh-keygen
,生成公私钥,将公钥命名为authorized_keys
,设置权限git:git 0600
。将私钥复制回本地,本地建立ssh配置,并且授予私钥权限0600。
之后,尝试使用ssh命令连接服务器,连接被拒绝。
我做的几点排查:
auth.log没有任何验证失败信息
/etc/ssh/sshd_config
中已经设置了
RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys
确认各个文件权限完全正确
git用户没有加入/sbin/nologin
(测试用)
由于是ubuntu不存在selinux
root用户可以正常登陆
运行ssh hexo(配置中的Host名) -vvv
信息如下:

最离奇的是以我自己的了解,我竟然没有从中看出任何连接被拒绝的信息。。。
还望各位大神不吝赐教,感谢!
