HK2000-如何修改数采IP以及网关等
常用操作：
Ctrl+C结束当前程序
Ctrl+BackSpace 强制退格，当输入错误，出现^H时，可使用改快捷键强行退格。
VI操作：
1.打开文件vi 文件名
2.设置编辑模式。按i 表示将当前文本设置成编辑模式，需要修改文件时需要先按i设置当前文本为编辑状态。
3.保存退出操作：按Esc 后按：wq
数采的IP信息存储到/usr/ete/rc.local 文件中，内容如下：
/sbin/ifconfig lo 127.0.0.1 up
/sbin/ifconfig eth0 172.19.190.3 netmask 255.255.255.0 up //IP 掩码
/sbin/route add default gw 172.19.190.1 //网关
如果需要修改IP，网关，掩码可通过修改该文件后，下一次重启数采后，IP信息会自动进行加载。
编辑rc.local命令 vi /usr/etc/rc.local
修改后查看命令 cat /usr/etc/rc.local
