1 Debian下进行4G模块EC20拨号

1.1 创建以下文件（配置适用于中国联通）

  • /etc/ppp/peers/quectel-pppd
# /etc/ppp/peers/quectel-pppd
# Usage:root>pppd call quectel-pppd
#Modem path, like /dev/ttyUSB3,/dev/ttyACM0, depend on your module, default path is /dev/ttyUSB3
/dev/ttyUSB2 115200
#Insert the username and password for authentication, default user and password are test
user "test" password "test"
# The chat script, customize your APN in this file
connect 'chat -s -v -f /etc/ppp/peers/quectel-chat-connect'
# The close script
disconnect 'chat -s -v -f /etc/ppp/peers/quectel-chat-disconnect'
# Hide password in debug messages
hide-password
# The phone is not required to authenticate
noauth
# Debug info from pppd
debug
# If you want to use the HSDPA link as your gateway
defaultroute
# pppd must not propose any IP address to the peer
noipdefault
# No ppp compression
novj
novjccomp
noccp
ipcp-accept-local
ipcp-accept-remote
local
# For sanity, keep a lock on the serial line
lock
modem
dump
nodetach
# Hardware flow control
nocrtscts
remotename 3gppp
ipparam 3gppp
ipcp-max-failure 30
# Ask the peer for up to 2 DNS server addresses
usepeerdns
  • /etc/ppp/peers/quectel-chat-connect
ABORT "BUSY"
ABORT "NO CARRIER"
ABORT "NO DIALTONE"
ABORT "ERROR"
ABORT "NO ANSWER"
TIMEOUT 30
"" AT
OK ATE0
OK ATI;+CSUB;+CSQ;+CPIN?;+COPS?;+CGREG?;&D2
# Insert the APN provided by your network operator, default apn is 3gnet
OK AT+CGDCONT=1,"IP","3gnet",,0,0
OK ATD*99#
CONNECT
  • /etc/ppp/peers/quectel-chat-disconnect
ABORT "ERROR"
ABORT "NO DIALTONE"
SAY "\nSending break to the modem\n"
""  +++
""  +++
""  +++
SAY "\nGoodbay\n"

1.2 开始拨号

sudo pppd call quectel-pppd

1.3 设置DNS

还需要修改如下文件加入DNS的配置： 

vi /etc/systemd/resolved.conf

填入pppd拨号时返回的DNS, 例如114.114.114.114: 

[Resolve]
DNS=114.114.114.114

重新启动systemd-resolved服务： 

sudo systemctl daemon-reload
sudo systemctl restart systemd-resolved.service

必要时还要停止其他网口: 

sudo ifconfig eth0 down
sudo ifconfig eth1 down
