ssh无法连接到服务器

Question

使用ssh无法登陆服务器，服务器是我刚买的砖瓦工，无论怎么重装系统还是不行，我能确定输入密码都是正确的。
我用的 Mac terminal, 服务器系统是centos6
整个系统登录对话及debug如下所示：

最后再说一句，我能确定输入密码是正确的，但是老是出现不允许，不知道怎么回事，请各位帮忙看一下。

Answer 1

ssh lgq@176.122.138.37 试一试

Answer 2

呃呃呃呃，没有root账户吗，我还没遇到过这种情况哎，有没有被坑啊？

Answer 3

之前我遇到过类似的问题

某些时候，在terminal下粘贴的时候会有一些类似[A [e 这样的字符被带进去，原因我也不知道

不过你可以试试完全退出terminal重新打开再试试
