ssh密码方式登陆Server

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

用ssh -v去连有问题的服务器，会有比较详细的调试信息在屏幕上输出，可以帮助判断是哪一步出了问题。

提示路径不正确??

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
