Natürlich müssen die weg. Sonst ist die Zeile quasi 'nicht existent' für den Dienst.

[ostseereiter]

@thomas-braun
ok nun kommt diese ausgabe schon mal nicht schlecht aber wohl noch ein Fehler.

andy@debian:~$ sudo upsdrvctl start
Network UPS Tools - UPS driver controller 2.7.4
Network UPS Tools - Generic HID driver 0.41 (2.7.4)
USB communication driver 0.33

Fatal error: 'maxretry' is not a valid variable name for this driver.

Look in the man page or call this driver with -h for a list of
valid variable names and flags.

@ostseereiter
Bist du sicher, dass du den richtigen Treiber für deine USV angegeben hast? Oder nur die gleichen Einstellungen aus dem HowTo 1:1 übernommen?
Das muss natürlich auf deine Situation angepasst werden.

[ostseereiter]

@thomas-braun sagte in USV:

HowTo 1:1 übernommen
1:1 übernommen

[ostseereiter]

@ostseereiter
was gibt man dann dort ein?

[Thomas Braun]

@ostseereiter

Und wer sagt dir, dass für deine Hardware nicht andere Einstellungen gelten?

[ostseereiter]

@thomas-braun
das verstehe ich kann nicht gleich sein aber wie macht man das und wo finde ich das?

[Thomas Braun]

@ostseereiter
Von der usbid her ist das die gleiche Hardware wie bei @foxriver76 .

[Homoran]

@ostseereiter sagte in USV:

Fatal error: 'maxretry' is not a valid variable name for this driver.

wo hast du denn das maxretry eingegeben?

[ostseereiter]

@thomas-braun sagte in USV:

@ostseereiter
Von der usbid her ist das die gleiche Hardware wie bei @foxriver76 .

Der Hersteller zumindest ist gleich. Wie kann man dnn die USBID auslesen?

[Homoran]

hast du bereits!

@ostseereiter sagte in USV:

[ostseereiter]

@homoran
ja aber wo trägt man diese ein?

[Homoran]

@ostseereiter sagte in USV:

ja aber wo trägt man diese ein?

nirgends, damit meldet sich das Gerät.

Aber

@homoran sagte in USV:

wo hast du denn das maxretry eingegeben?

steht außer der drei Zeilen nichts sonstiges in der conf?

# Configuration directives
# ------------------------
#
# These directives are used by upsdrvctl only and should be specified outside
# of a driver definition:
#
#    maxretry: Optional.  Specify the number of attempts to start the driver(s),
#              in case of failure, before giving up. A delay of 'retrydelay' is
#              inserted between each attempt. Caution should be taken when using
#              this option, since it can impact the time taken by your system to
#              start.
#
#              The default is 1 attempt.
#
#  retrydelay: Optional.  Specify the delay between each restart attempt of the
#              driver(s), as specified by 'maxretry'. Caution should be taken
#              when using this option, since it can impact the time taken by your
#              system to start.
#
#              The default is 5 seconds.
#
# These directives are common to all drivers that support ups.conf:
#
#  driver: REQUIRED.  Specify the program to run to talk to this UPS.

#
# sdorder: optional.  When you have multiple UPSes on your system, you
#          usually need to turn them off in a certain order.  upsdrvctl
#          shuts down all the 0s, then the 1s, 2s, and so on.  To exclude

#              connected.  By enabling the 'synchronous' flag
#              (value = 'yes'), the driver will wait for data to be

#       port = /dev/ttyS0
#       desc = "Web server"
#
# If your UPS driver requires additional settings, you can specify them

#
# [myups]
#       driver = mydriver
#       port = /dev/ttyS1

endlich!

Ob das korrekt ist mitten in der Anleitung die # zu entfernen und das als Config zu nehmen weiß ich nicht.

Ansonsten würde ich zum testen jetzt einfach die Zeile mit den maxretry auskommentieren.

EDIT:
das Problem wird die Zeile vor maxretry sein. Die war doch eben noch auskommentiert, oder?
Dort unbedingt ein # vorsetzen sonst ist das ein (ungültiger) Befehl -> set maxretry....
