Hello,

Looks like you are getting an error where the executable is not found. Can you confirm that arp_standin does exist in /usr/local/bin/?

looks like I can just make a symlink 🤷‍♂️

restarted the pi today, re-started the services and now it's failing. I'm still pointing to the symlink

Force a restart of the service then run:

journalctl _PID=(whatever PID the service had)

(Journalctl allows you to interact and view multiple system log files at once and merges them). See if that yields any new information

Hey @marclundgren 👋

It looks like the issue here is that the script can't find the pcaprub gem:

Apr 24 20:41:27 torrentpi arp_standin[4214]: /usr/lib/ruby/vendor_ruby/rubygems/core_ext/kernel_require.rb:85:in `require': cannot load such file -- pcaprub >

You could try running sudo gem install pcaprub to install it globally, though there is probably a better way to do it without using sudo.

It would be great to have a Docker image to help avoid installation quirks like this. If anybody is interested to submit a PR for one, that would be a big help.
