开机shell拨号上网

设置    
stty -F /dev/ttyUSB3 raw speed 115200 cs8 -parenb -cstopb cread clocal
stty -F /dev/ttyUSB3


查看输出
cat /dev/ttyUSB3
输入
echo -e "AT \r" > /dev/ttyUSB3
echo -e "AT+CPIN? \r" > /dev/ttyUSB3
echo -e "AT+CIMI \r" > /dev/ttyUSB3
echo -e "AT+CSQ \r" > /dev/ttyUSB3
echo -e "AT+CNSMOD? \r" > /dev/ttyUSB3
echo -e "AT+CEREG? \r" > /dev/ttyUSB3

echo -e "AT\$QCRMCALL=1,1 \r" > /dev/ttyUSB3

ifconfig wwan0 up

udhcpc -i wwan0

ping -I wwan0 www.baidu.com

调整默认网卡

default开头的就是默认网关
ip route show

删除默认网关配置，192.168.1.1 不是有线网的ip地址，而是有线网的网关地址
route del default gw 192.168.1.1

添加网关为默认地址，72.28.70.25 是IP地址，不是网关地址
route add default gw 172.28.70.25

自动登录

修改图形桌面配置,编辑文件/etc/gdm3/custom.conf
[daemon]
AutomaticLoginEnable=true #启用自动登录
AutomaticLogin=root       #指定root用户为自动登录用户
