SSH服务

1、安装

sudo apt-get install openssh-server

2、启动

sudo service ssh start

3、查询状态（可选）

sudo service ssh status 
或者
sudo ps -e | grep ssh

4、配置

sudo vim /etc/ssh/sshd_config 

这里可以修改端口号，默认22端口。
在页面最后添加以下配置，用于防止Putty无法连接的BUG。

KexAlgorithms curve25519-sha256@libssh.org,ecdh-sha2-nistp256,ecdh-sha2-nistp384,ecdh-sha2-nistp521,diffie-hellman-group14-sha1 

如果没有添加上面配置，Putty连接时会提示expected key exchange group packet from server错误，若不使用Putty这里可以不进行配置。

最后再更新一下配置

systemctl restart sshd

5、关闭防火墙
如果开启了ufw建议进行关闭

sudo ufw disable

6、配件静态IP
首先找到外网的网卡名称，执行ifconfig -a命令返回如下：

eth0      Link encap:以太网  硬件地址 00:11:32:5f:94:4f
          inet 地址:10.0.0.8  广播:10.0.0.255  掩码:255.255.255.0
          inet6 地址: fe80::4829:79b3:b677:c1c4/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  跃点数:1
          接收数据包:60887 错误:0 丢弃:171 过载:0 帧数:0
          发送数据包:6114 错误:0 丢弃:0 过载:0 载波:0
          碰撞:0 发送队列长度:1000
          接收字节:15933461 (15.9 MB)  发送字节:721431 (721.4 KB)

lo        Link encap:本地环回
          inet 地址:127.0.0.1  掩码:255.0.0.0
          inet6 地址: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  跃点数:1
          接收数据包:10107 错误:0 丢弃:0 过载:0 帧数:0
          发送数据包:10107 错误:0 丢弃:0 过载:0 载波:0
          碰撞:0 发送队列长度:1000
          接收字节:1313818 (1.3 MB)  发送字节:1313818 (1.3 MB)

例如以上eth0为外网网卡名称

修改网络配置文件sudo vi /etc/network/interfaces

auto eth0
iface eth0 inet static
address 10.0.0.8
netmask 255.255.255.0
gateway 10.0.0.1
dns-nameserver 10.0.0.1

重启网络服务

sudo /etc/init.d/networking restart

修改更新源

1、打开更新源文件

sudo vi /etc/apt/sources.list

2、将以下内容进行替换
