服务器环境:操作系统:ubuntu 14.04 64bit
客户端环境:deepin 64bit
服务器端设置:
1.执行以下命令，将“/etc/ssh/sshd_config”中的“PasswordAuthentication”值修改为“yes”。
sudo vi /etc/ssh/sshd_config
2.执行以下命令，重新加载sshd服务。
sudo service sshd reload
3.为安全起见，建议重置Linux弹性云服务器普通帐户的密码 执行以下命令，重置用户名为“linux”的弹性云服务器密码。sudo passwd linux
4.按照回显提示，输入新密码，按“Enter”5.重新输入设置的新密码，按“Enter”。
6.系统回显如下时，表明重置成功。
passwd: all authentication tokens updated successfully.
客户端:
客户端通过ssh方式连接服务器出错,官网提供的登陆格式如下:
lsj@lsj-pc:~$ ssh 122.112.224.189 ssh_exchange_identification: read: Connection reset by peer连接后报错
ping 服务器发现网络连接正常

解决方案:
用root身份登陆服务器:
lsj@lsj-pc:~$ ssh root@122.112.224.189输入root密码
