General network failure requiring a reboot

From Cumulus MX version 3 build 3044 the development baton passed to Mark Crossley. Mark has been responsible for all the Builds since, and has recently released Cumulus MX version 4. He has made the code available on GitHub. It is Mark's hope that others will join in this development, but at the very least he welcomes your ideas for future developments (see Cumulus MX Development suggestions).

General network failure requiring a reboot

Post by HansR »

Recently I have network issues which result in general failures as you find in the attached fragment of the log - I will not attach the full log because that would not add useful info. I can't read the station, can't send files to the server and it can't send the email that receiving data has stopped. I cannot access my RPi anymore through SSH so it all has blocked. I can't find a reason, the only thing which helps is a reboot which I now do by unplugging/replugging.

Is there any way CMX can now - in the current situation - activate a reboot?

Anybody an idea how to check connections in a script and if they all fail do a reboot?

If I am away I cannot physically unplug/replug the RPi so it has to be automated.
Looking for ideas.

Re: General network failure requiring a reboot

Post by broadstairs »

I think this is going to be tricky since a 'shutdown now' or 'reboot' command in Linux requires the root password. If you Google you will find several suggestions on how to achieve this in a crontab entry, and others which remove the need for a password from the shutdown/reboot commands (highly dodgy!). As yet I've not found a solution which I would be happy with but I've not looked for long ;)

What would be wrong with the sudo reboot command in the shell script? I do this already in the crontab
NB: the script would be on a protected RPi, not reachable from outside.

Nothing if your system does not require a password for sudo commands.

Nothing in principle and if you can fire the script from CMX when this error happens it should work. Make sure the CMX user is authorised for sudo.

I don't like sudo but that's a personal thing as anyone with access to that user can do nasty things.
