I have Fedora 20 installed, using MATE desktop and zshell and something weird is going on.
I get lots of odd unexplained beeps from my speakers, even though the volume is turned down to zero, so something is going on in the background; and last night, at 0200, after I had
shutdown earlier at about 2300, I found that the LED on my one Terabyte USB hard drive was on. I did not touch anything and it went off soon after I noticed it.
I have searched the Internet for a solution, but I can't understand the arcane acronyms and details of most of the information. I would like to understand what is going on, but I don't know where to look. I believe that the shutdown machine would be in run-level 1, with some things running, but investigating that also leads me into deep, unfathomable waters.
I have looked in crontab crond and corosync, and anything else that looks likely, with nothing looking suspicious, and really, no clue about what I should expect.
crontab -e showed this, left over from my experiments a while ago with scheduling (I added
# to make the line a comment, just now, to stop it):
* * * * * /testrsync/zenitytest.sh >/dev/null 2>&1
I also note, with embarrassment, that
/test.. is not in my home directory.
I forgot to mention, in my first posting of this question, that once a day in the late afternoon or evening, the computer suddenly, without warning, shuts down and reboots to my normal login screen, but without losing anything I was doing. It seems to happen as I open a new tab in Maxthon web browser, but I am not sure of this as it takes me by surprise every time.
This is all a paean to ignorance, so my question is: please how can I find out what is going on?
