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
