Working upscmd.py file with DSM 7.2 and latest telnetlib

[nntantidakis]

Latest libs require encoding of strings. Here is a fully working upscmd.py file, that i personally tested that its working.

#!/bin/python2
import sys
import telnetlib

user = "<username>"
pwd = "<password>"

if len(sys.argv) == 2:
    cmd = sys.argv[1]
else:
    print("the ups command to issue is missing.")
    print("example: upscmd.py beeper.enable")
    exit(1)


tn = telnetlib.Telnet("127.0.0.1", 3493)

tn.write(str.encode("USERNAME {0}\n".format(user)))
response = tn.read_until(b"OK", timeout=2)
print ("USERNAME cmd status: {0}".format(response.strip()))

tn.write(str.encode("PASSWORD {0}\n".format(pwd)))
response = tn.read_until(b"OK", timeout=2)
print ("PASSWORD cmd status: {0}".format(response.strip()))

tn.write(str.encode("INSTCMD ups {0}\n".format(cmd)))
response = tn.read_until(b"OK", timeout=2)
print ("INSTCMD cmd status: {0}".format(response.strip()))

tn.write(str.encode("LOGOUT\n"))
print (tn.read_all())

Also the command for service restart is synosystemctl restart ups-usb. And while running the script if you get access-denied, set to upsd.users the actions to SET and instcmd to ALL. After that restart service, and it will work like a charm.

Hi

I'm running DSM 7.2.1-69057 Update 3 and for some weird reason, can't make this work!

I've added the following to /etc/ups/upsd.users and /usr/syno/etc/ups/upsd.users (I have both no idea why)

    password = **********
    actions = SET
    instcms = beeper.enable beeper.disable ups.beeper.status

follower by systemctl restart ups-usb

checked the output of upsc

and then tried to disable the beeper with no sucess

Your ups must support the beeper disable command.. From your output it seems that the command was sent successfully to your ups but this function does not exist by your ups. Check your manual to see its correct syntax, and most importantly that indeed there is this function available for your setup.

[jonferreira]

I'm pretty sure it is supported, not only I can disable it with the manufacturer software (if I connect it to my pc via usb) but I also have another that I can disable with a standard NUT installation

[jonferreira]

a quick dump of the supported commands outputs this:

ash-4.4# python2 /root/upscmd_list.py


BEGIN LIST CMD ups

CMD ups beeper.toggle

CMD ups load.off

CMD ups load.on

CMD ups shutdown.return

CMD ups shutdown.stayoff

CMD ups shutdown.stop

CMD ups test.battery.start

CMD ups test.battery.start.deep

CMD ups test.battery.start.quick

CMD ups test.battery.stop

END LIST CMD ups

OK Goodbye

CMD ups test.battery.stop

END LIST CMD ups

You have toggle. not disable/enable. So modify your files accordingly to send the command beeper.toggle . Maybe instantly calling the sh with command toggle to work, eg sudo /root/ups_beeper_control.sh toggle

[jonferreira]

yes working on it, think I may be going on the right direction

USERNAME cmd status: OK
PASSWORD cmd status: OK
INSTCMD ups beeper.toggle

INSTCMD cmd status: ERR ACCESS-DENIED
OK Goodbye

that said, already added beeper.toggle to the allowed commands list and restarted the service...I'm missing something

[nntantidakis]

Yu must add this command on the permissions of the user. Try the one I've mentioned before (about giving ALL) on the instcmd.

[jonferreira]

yeah I've tried with all and same results, I'm clearly missing something basic...

I have a Fortron/FSP ECO 800-FR UPS, connected to Synology DS224+ NAS device.
The beeper is disabled like that through my Synology DS224+ NAS device:

synologyuser@synologynas:~/UPS$ sudo vim /etc/ups/upsd.users
synologyuser@synologynas:~/UPS$ sudo tail -4 /etc/ups/upsd.users

        instcmds = beeper.toggle

In order to enable it back, just run last command python2 upscmd.py beeper.toggle again.
