权限被拒绝(publickey,keyboard-interactive)

我试图用ssh连接到planetlab节点。 它会抛出像Permission denied(publickey,keyboard-interactive)这样的错误。 这是什么意思? 这里是详细的例外。

您需要更改远程服务器中的sshd_config文件(可能位于/etc/ssh/sshd_config )。

更改

 PasswordAuthentication no 

 PasswordAuthentication yes 

然后重新启动sshd守护进程。

您可能要仔细检查authorized_keys文件权限:

 $ chmod 600 ~/.ssh/authorized_keys 

较新的SSH服务器版本在这方面非常挑剔。

服务器首先尝试通过公钥对您进行身份validation。 这不起作用(我想你还没有设置一个),所以它回落到“键盘交互”。 然后它应该问你一个密码,这可能是你没有得到正确的。 你看到密码提示吗?
