问题: SSH远程登录主机失败,求路过的高手指点迷津
描述:

Permission denied (publickey,password).
普通用户可以连接,用root连接就是不行,密码是对的,今天找了一天的答案,没找到,基本上都是说将permitROOTLogin no 改为permitROOTLogin yes 我改了,也重启服务了,还是不行 信息如下:

解决方案1:

新手上路,有点坑,不过已经解决了,在目标主机上也要配置sshd_config文件,允许root登录就行了。

解决方案2:

应该是shell的问题,你可以试一下Git Bash https://git-scm.com/downloads。

解决方案3:

普通用户行,root不行,就是说明root被禁止了,改一下ssh的配置,再试试。
按道理,不让root远程登陆是合理的,是最佳实践,想执行root命令你可以sudo嘛。
