用户添加后服务器意外关闭网络连接Putty

添加用户后

[root@ctxsv-gl4j ~]# useradd -m mtteam
[root@ctxsv-gl4j ~]# passwd mtteam
Changing password for user mtteam.
New password:
Retype new password:
passwd: all authentication tokens updated successfully.
[root@ctxsv-gl4j ~]#

putty：使用刚刚创建的‘mtteam’登录，我收到以下消息：

服务器意外关闭网络连接

注意：使用“root”登录效果很好

我希望用户不要以 root 身份登录，而是登录 su -mtteam。这是来自 /var/log/secure

答案1

伙计，请阅读你自己发布的错误。mtteam 需要成为这些组的成员，否则它将无法工作。（或者更改 PAM 配置）

答案2

检查 /etc/ssh/sshd_config 中是否存在且未注释的 AllowUsers，如果是，请在此处添加此用户。同时运行

 grep mtteam /etc/passwd

并查看它是否具有有效的shell（例如/bin/bash）。
