Hi Rintje,

Thanks for all the information. Wonder if you can attach the version compiled for 25 sec time out. Seems I need a linux environment, if I want to compile myself.

Ok, see attachment.

Hey Sorna,

Just one more thing: while i was reconfiguring my NAS solution, the solution i described to you didn't work anymore for me. After some investigation i suddenly remembered that in the original working solution i also had to change the startup script /ffp/start/chkbutton2.sh. This modified startup script copies the chkbutton2 binary, backup.sh and cleanup.sh file to the hardware memory space, to prevent cleanup.sh from killing its own running process.
You said the solution already works for you, but for completeness of my solution i post the startup script here as well.

I had a similar issue with NUT running as a client. I wanted the DNS-323 to shutdown after a period of time after the ONBATT warning came from the NUT server. (stupid cheap serial only UPS doesn't work directly on the DNS-323).

I tried chkbutton2, but this didn't seem to work when called from a script (upssched.cmd). Eventually I put together a bit of a kludge to get it all to work.

Firstly, you need to make sure all fun_plug bits are stopped, so the disks can spin down (unless you are running ffp from a USB stick - which I am not). The only way I could reliably get this to work was to remove chkbutton2 and use cleanboot to shutdown ffp, then touch /tmp/shutdown after a timer expires to "trick" the DNS-323 into shutting down. It may not matter, but I also found things worked better if I didn't use /ffp/bin/sh, but busybox bourne sh (i.e. /bin/sh).

So my upssched.cmd looks like:

#!/bin/sh
LOGFILE=/ffp/log/upssched.log
case $1 in
  mainsoff)
    echo "`date` Script ${0} started with option: ${1}" > $LOGFILE
    echo "`date` Local Mains shutdown 90 seconds ago" >> $LOGFILE
    echo "`date` ${0} System powerdown in 15 seconds!" >> $LOGFILE
    /sbin/halt
    sleep 15
    touch /tmp/shutdown
    ;;
  forcedshut)
    echo "`date` Script ${0} started with option: ${1}" > $LOGFILE
    echo "`date` UPS Monitor has requested immediate shutdown" >> $LOGFILE
    echo "`date` ${0} performing system halt NOW!" >> $LOGFILE
    /sbin/halt
    sleep 5
    touch /tmp/shutdown
    ;;
  *)
    echo "`date` Script ${0} started with invalid option: ${1}" > $LOGFILE
    echo "`date` Script ${0} Stopping - no further action" >> $LOGFILE
    ;;
esac

It works for me, after many hours of testing and far too many reboots.....

The NUT config file upssched.conf also needs appropriate configuration to match the case statements above. e.g.

CMDSCRIPT /mnt/HD_a2/ffp/usr/local/ups/upssched-cmd
PIPEFN /mnt/HD_a2/ffp/var/state/ups/upssched/upssched.pipe
LOCKFN /mnt/HD_a2/ffp/var/state/ups/upssched/upssched.lock
AT ONBATT * START-TIMER mainsoff 90
AT ONLINE * CANCEL-TIMER mainsoff
AT LOWBATT * EXECUTE forcedshut
AT FSD * EXECUTE forcedshut

And the upsmon.conf file needs modification so that the various conditions trigger upssched too:

NOTIFYFLAG ONLINE        SYSLOG+EXEC
NOTIFYFLAG ONBATT        SYSLOG+EXEC
NOTIFYFLAG LOWBATT        SYSLOG+EXEC
NOTIFYFLAG FSD        SYSLOG+EXEC

I found that NUT has to run as root to make sure everything works ok, and make sure all the file paths exist!

Hope this helps.

Hi, I have two questions.

in cleanup.sh there are references to cleanboot.conf and /ffp/share/cleanboot directory.
does this mean that they are required for chkbutton2?

second question is how custom scripts on shutdown is run.
i couldn't find any information describing them.

so i should install cleanboot too?

if, for instance, i made a script called abc.sh and put it in the same folder as the chkbutton2 executable, would the new script be run on shutdown?

what if i want to sync data from the harddrive to an external usb harddrive before shutdown using rsync?
would i just add a line to cleanup.sh?

Hi !
I have DNS-323 rev-B, fw-1.09 with installed "chkbutton2" from #18 post. "chkbutton2" work good. But in Web page DNS-323 command "restart" work correctly, and command "shutdown" work NOT correctly, DNS-323  is not switched off. In telnet commands "poweroff2" and "reboot2" work good. If do "chkbutton2 stop", and then "chkbutton2 start", command "shutdown" in Web page not work too. I reinstall "chkbutton2" with "rintje" files from  #51, #53 posts. Has changed nothing. What have I made incorrectly? Whether there is a problem decision?
Thanks.

p/s
DNS-323 rev-A dont work correctly in Web page too :-(
