1. INSTALL PACKAGES

INSTALL=""

1. WRITE CONFIG

CONFIG="" CONFIG="${CONFIG}\n[Dialer Defaults]" CONFIG="${CONFIG}\nInit2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0" CONFIG="${CONFIG}\nModem Type = Analog Modem" CONFIG="${CONFIG}\nISDN = 0" CONFIG="${CONFIG}\nInit1 = ATZ" CONFIG="${CONFIG}\nModem = $USB_DEV" CONFIG="${CONFIG}\nBaud = $USB_BAUD" CONFIG="${CONFIG}\n" CONFIG="${CONFIG}\n[Dialer pin]" CONFIG="${CONFIG}\nInit3 = AT+CPIN=$PIN" CONFIG="${CONFIG}\n" CONFIG="${CONFIG}\n[Dialer connect]" CONFIG="${CONFIG}\nCarrier Check = no" CONFIG="${CONFIG}\nInit4 = AT+CGDCONT=1,\"IP\",\"$GSM_DST\"" CONFIG="${CONFIG}\nStupid Mode = 1" CONFIG="${CONFIG}\nPhone = $GSM_NUMBER" CONFIG="${CONFIG}\nDialer Command = ATD" CONFIG="${CONFIG}\nDial Attemps = 2" CONFIG="${CONFIG}\nUsername = $GSM_USER" CONFIG="${CONFIG}\nPassword = $GSM_PASS"

echo -e "$CONFIG" > $WVDIAL_CONF chmod u=rw,go=r $WVDIAL_CONF echo "wrote '$WVDIAL_CONF'"

1. CHANGE SOME PERMISSIONS TO BE ABLE TO EXECUTE AS NON-ROOT

adduser $USERNAME dip adduser $USERNAME dialout

echo "changing permissions of ppp-files" chmod o+x,g+s $PPPD chown $USERNAME:$GROUPNAME $PAP_SECRETS chown $USERNAME:$GROUPNAME $CHAP_SECRETS

1. WRITE amok-script

cd `dirname $0` SCRIPT="" SCRIPT="${SCRIPT}\n#!/usr/bin/env python" SCRIPT="${SCRIPT}\n" SCRIPT="${SCRIPT}\nfrom time import sleep" SCRIPT="${SCRIPT}\nimport os" SCRIPT="${SCRIPT}\nimport RPi.GPIO as GPIO" SCRIPT="${SCRIPT}\n" SCRIPT="${SCRIPT}\nGPIO.setmode(GPIO.BCM)" SCRIPT="${SCRIPT}\nGPIO.setup(23, GPIO.IN)" SCRIPT="${SCRIPT}\nGPIO.setup(24, GPIO.IN)" SCRIPT="${SCRIPT}\nGPIO.setup(25, GPIO.IN)" SCRIPT="${SCRIPT}\n" SCRIPT="${SCRIPT}\nwhile True:" SCRIPT="${SCRIPT}\n\tif ( GPIO.input(23) == False ):" SCRIPT="${SCRIPT}\n\t\tos.system('pwd &')" SCRIPT="${SCRIPT}\n\tif ( GPIO.input(24) == False ):" SCRIPT="${SCRIPT}\n\t\tos.system('pwd &')" SCRIPT="${SCRIPT}\n\tif ( GPIO.input(25)== False ):" SCRIPT="${SCRIPT}\n\t\tos.system('pwd &')" SCRIPT="${SCRIPT}\n\tsleep(1);"

echo -e "$SCRIPT" > $AMOK_PY chmod u=rwx,go= $AMOK_PY echo "wrote '$AMOK_PY'" </source>
