Ubuntu配置新安装配置折腾好大一会

Posted 2020-08-09

-------------------------------------

设置root管理员账户密码：

sudo passwd root

输入普通用户密码后修改。

修改后退出，用root登录

安装远程服务：

$ sudo apt-get install openssh-server

$ sudo /etc/init.d/ssh restart

检查服务状态：

systemctl --failed

Server responded "Algorithm negotiation faild."无法远程，

vi /etc/ssh/sshd_config  

最后添加如下信息：

Ciphers aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,3des-cbc,arcfour128,arcfour256,arcfour,blowfish-cbc,cast128-cbc

MACs hmac-md5,hmac-sha1,[email protected],hmac-ripemd160,hmac-sha1-96,hmac-md5-96

KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group1-sha1,[email protected]

无法用root远程，可以对 openssh server进行配置

$ sudo vi /etc/ssh/sshd_config

找到PermitRootLogin 一行，改为PermitRootLogin yes

添加和静态ip有关的参数，注释动态DNS：

# The primary network interface

iface eth0 inet static

address 192.168.1.247

netmask 255.255.255.0

gateway 192.168.1.2

$sudo ifdown eth0

$sudo ifup eth0

测试链接：正常。

附下边查资料参考的页面：

安装 openssh-server后，使用ssh客户端连接时可能报此错误，情况如下图所示

server responded "algorithm negotiation failed”

解决方法

修改ssh的配置文件 /etc/ssh/sshd_config

在配置文件中添加：

Ciphers aes128-cbc,aes192-cbc,aes256-cbc,aes128-ctr,aes192-ctr,aes256-ctr,3des-cbc,arcfour128,arcfour256,arcfour,blowfish-cbc,cast128-cbc

MACs hmac-md5,hmac-sha1,[email protected],hmac-ripemd160,hmac-sha1-96,hmac-md5-96

KexAlgorithms diffie-hellman-group1-sha1,diffie-hellman-group14-sha1,diffie-hellman-group-exchange-sha1,diffie-hellman-group-exchange-sha256,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group1-sha1,[email protected]

重启sshd服务后

就可正常连接了

传送个Python试一下
