0x02.设置静态IP地址

搬家之后rpi-masterrpi-slave均不再使用无线连接(分别是5G2.4GWiFi),全部以菊花插网线的方式上网
修改/etc/dhcpcd.conf,末尾追加

0x05.安装SmokePing

参照How to install SmokePing还是算了吧,真的需要一键安装脚本,然后谷歌看到树莓派上有编译好的包,于是立即从cn-py-dl-c8切换到rpi-master来安装了

Description: latency logging and graphing system
SmokePing consists of a daemon process which organizes the
latency measurements and a CGI which presents the graphs.
.
With SmokePing you can measure latency and packet loss in your network.
SmokePing uses RRDtool to maintain a longterm datastore and to draw pretty
graphs giving up to the minute information on the state of each
network connection.
