SSH:权限被拒绝(公钥、gssapi-with-mic、密码)

ghe*_*kin 27 ssh ssh-agent

================================================== ==================

更新:原来 sshd 的配置host2不允许密码登录。感谢人们回答这个问题。

================================================== ==================

场景:为我的大学项目与一家公司合作。我需要先使用 PuTTy SSH 进入host1,然后从那里 SSH 进入host2(见下文)。我在 host2 上获得了用户名和密码。

我根本无法访问 host2,所以我不知道它的sshd_config.

这是当我试图使用SSH连接发生了什么host2host1

我想知道我去公司之前有什么可以做的吗?

主机不接受您尝试的用户名和密码。这意味着您连接到错误的服务器,或者用户名或密码不正确。您应该要求管理员检查日志host2,这应该会告诉您这三个中的哪一个。

  • 就像你能不能再蠢一点,当然我有正确的密码。然后你会记住不同的键盘布局。谢谢你让我重温:) (2认同)

第一的

 chmod 700 .ssh

进而 :

 chmod 600 .ssh/authorized_keys

并测试这个:

restorecon -r -vv .ssh/authorized_keys

  • 这有效。谢谢! (3认同)
