Vidím to v logoch, lebo som nastavil logovanie stavu offline/online a tiež som nastavil skript aby sa R-Pi každú pol-hodinu reštartoval ak je systém offline.To restartovani celeho RPi je zbytecne, staci pokud je to opravdu nutne restartovat sit, nebo jen DHCP, ale idealni by bylo zjistit pricinu. Mohl by jsi detailne popsat "som nastavil logovanie" a taky by se hodil ten " som nastavil skript" skript.
#!/bin/bash
# internet connection check based on pinging public dns ip(s)
IPtoCheck=("208.67.222.222" "208.67.220.220" "1.1.1.1" "1.0.0.1" "9.9.9.9" "149.112.112.112")
countOnline=0
for ip in "${IPtoCheck[@]}"
do
sleep 10
if ping -q -c 1 -W 1 $ip >/dev/null
then
echo "$ip is online"
countOnline=$((countOnline+1))
else
echo "$ip is offline"
fi
done
if [ $countOnline -gt 0 ]
then
echo "we are probably online"
else
echo "we are probably offline"
# we are probably offline - need to reboot and hope modem will reconnect after reboot
echo "rebooting..."
sleep 60
echo $(date)" >> "$(realpath $0)" >> no internet connection (rebooting now)" >> /home/openhabian/logs
sudo reboot
fi
Tu je skript modem-autoconnect.sh, ktorý spúšťam cez systemd vždy pri štarte PC.
V skripte som cenzuroval môj PIN pre SIM kartu v modeme, inak je skript ako originál.
#!/bin/bash echo $(date)" >> "$(realpath $0)" >> modem autoconnect starts" /home/openhabian/logs # if I do not use this delay - it sometimes does not work sleep 5 # unlocking the SIM card with PIN sudo mbimcli -d /dev/cdc-wdm0 -p --enter-pin=**** # if I do not use this delay - it sometimes does not work sleep 3 # connecting the modem to the internet sudo mbim-network /dev/cdc-wdm0 startTu je uvítacie info ktoré vidím po pripojení sa do terminálu cez SSH (zvýraznil som "podozrivé" riadky).
