It’s been working about 13 days, and working fine.
In that time I’ve done pretty much nothing on OH due to lack of time. I did install hping as per:
but it didn’t work properly for me so I’ve commented out all the items / rules etc. Could it be this that has changed something? The problem is that I can’t say it the nut was working before I did this as I’ve not been on OH to see the few days before it…
