Automatic Ethernet connection checking and informing in case of troubles ?

[Dré]

Good morning Joep
In the script the command to send this information by e-mail would be missing, right?
How can I send this information by e-mail every day at night as you comment? (only one e-mail per day, or every week)
Thank you very much for sharing your knowledge in the forum

Hi Josema,

Below the complete script to get all the information, write it to the log and send it by email using the default email function.
You can use this script as a scheduled script and run it every x days or once a week.
What you need to do is to set the correct receiver email address in the last line of the script and if you want you can change the Dutch words to your own language.

Code:

--status van de homeLYnk ophalen, loggen en mailen
require('json')
require('socket.http')

ip = io.readproc('if-json')
ip = json.decode(ip)
log("IP adres: " ..ip.eth0.inetaddr)

socket.http.timeout = 5
data = socket.http.request('http://ip-api.com/json')
if data then
  data = json.decode(data)
  log("WAN IP: "..data.query)
  log("Plaats: "..data.city)
  log("Provincie: "..data.region)
  log("Land: "..data.countryCode)
  log("Latitude: "..data.lat)
  log("Longitude: "..data.lon)
else
  log("Er is mogelijk geen internetverbinding actief")
end

log("Naam: " ..socket.dns.gethostname())

io.input("/sys/class/net/eth0/carrier")
carrier = io.read("*line")
if carrier == "1" then
  log("Verbonden met het netwerk")
else
  log("Geen verbinding met het netwerk")
end

io.input("/sys/class/net/eth0/operstate")
state = io.read("*line")
if state == "up" then
  log("De netwerkverbinding is actief")
else
  log("De netwerkverbinding is inactief")
end

mail('your@email.com', subject, message)

I was trying to use this script, this script is working, i see the results by log, but i got a error on line 65 'mail('your@email.com', subject, message)'
I know it is 'mail' but i dont know how to fix this.
What script do i need to use it and do i put it on user.libraries?
