+## 5. 系统配置
+
+### 5.1. Buildroot 系统
+
+- 用户：root
+- 密码：firefly
+
+#### 5.1.1. 以太网配置
+
+Buildroot 的网络配置需要使用到 /etc/network/interfaces 配置文件，配置完成之后，运行：
+
+```bash
+/etc/init.d/S40network restart
+```
+
+即可重启网络。手动调试可以直接使用：
+
+```bash
+ifdown -a
+# 和
+ifup -a
+```
+
+来重启网络。
+
+配置文件举例：
+
+如下配置文件将 eth0 网卡设置为动态 IP 地址，将 eth1 设置为静态 IP 地址
+
+```bash
+auto lo
+iface lo inet loopback
+
+auto eth0
+iface eth0 inet dhcp
+
+auto eth1
+iface eth1 inet static
+address 192.168.2.2
+netmask 255.255.255.0
+broadcast 192.168.2.255
+gateway  192.168.2.1
+```
+
+注意：/etc/network/interfaces 的文件格式要求比较严格，如果遇到：
+
+```bash
+Error: either "local" is duplicate, or "/24" is a garbage.
+```
+
+那么很有可能是配置文件中多了一个空格。
+
+#### 5.1.2. SSH
+
+官方发布的 SDK 默认已开启 ssh，用户为”root”，密码为”firefly”。
