Connecting a UPS to your Linkstation (USB models)
Installing Network UPS Tools (nut)
Prerequisites
Install the 2.6 kernel to get the new USB HID modules http://linkstationwiki.net/index.php?title=Category:Kernel
Setup your system to accept packages from the unstable branch (follow instructions for everything except the last step to "apt-get -t install xyz" ) http://www.linkstationwiki.net/index.php?title=Get_access_to_packages_from_the_Debian_unstable_branch#Unstable_Packages
Fix your localhost entry if applicable. This is a current bug with freelink 1.11 HG:
Modify /etc/hosts This line:
127.0.0.1 Linkstation
to
127.0.0.1 Linkstation localhost
if there was "127.0.0.1 localhost", this is good already, no need to change it.
Installing
apt-get -t unstable install nut nut-usb
which will also add the appropriate lib-usb. and install nut & nut-usb 2.0.4-2 or better
Config files setup
Now that you've installed nut, you must set it up. Follow instructions under /usr/share/doc/nut/README.Debian or use this quick and dry way:
cd /etc/nut/ cp /usr/share/doc/nut/examples/ups.conf . cp /usr/share/doc/nut/examples/upsd.conf . cp /usr/share/doc/nut/examples/upsmon.conf . cp /usr/share/doc/nut/examples/upsd.users . chown nut:nut * chmod 600 *
Edit ups.conf
Add this anywhere inside the file:
[myups]
driver = newhidups
port = auto
pollinterval = 10
desc = "My APC 1000 UPS":
Edit upsd.users
Add this anywhere inside the file:
[monuser]
password = blah
allowfrom = localhost
actions = SET
upsmon master
blah is the password you wish to use. Make sure you use the same one in upsmon.conf
Edit upsmon.conf
Add this line:
MONITOR myups@localhost 1 monuser blah master
blah is the password you wish to use. Make sure you use the same one in upsd.users
Edit /etc/default/nut
Modify the first few lines to:
# start upsd START_UPSD=yes
# start upsmon START_UPSMON=yes
Issue a reboot
to load the newhisups driver, upsd and upsmon
reboot
Verify UPS connectivity
Basic connectivity
newhidups -u root -D -D -a apc
You should see your UPS information showing up.
tail -1000 /var/log/syslog |grep ups
You should see something like this: Aug 11 15:31:38 LinkStation newhidups[1606]: Startup successful Aug 11 15:31:38 LinkStation upsd[1607]: Connected to UPS [myups]: newhidups-auto Aug 11 15:31:38 LinkStation upsd[1608]: Startup successful Aug 11 15:31:38 LinkStation upsmon[1610]: Startup successful Aug 11 15:31:38 LinkStation upsd[1608]: Connection from 127.0.0.1 Aug 11 15:31:38 LinkStation upsd[1608]: Client monuser@127.0.0.1 logged into UPS [myups]
Disabling the Beeper or changing UPS variables
Wish to disable that beeper that wakes you up at night ?
upsrw myups@localhost
The ups.beeper.status variable is likely Enabled.
upsrw -s ups.beeper.status myups@localhost Username (root): monuser Password: blah Enter new value for ups.beeper.status: 1
upsrw myups@localhost
Verify that ups.beeper.status now shows up as disabled Follow same method for changing other variables.
Power outage detection
If this all works, try removing power from your UPS to verify id the Linkstation will detect it. You should see this in your syslogs, again using
tail -1000 /var/log/syslog |grep ups
Aug 10 15:59:28 LinkStation upsmon[1613]: UPS myups@localhost on battery
Aug 10 16:04:39 LinkStation upsmon[1613]: UPS myups@localhost on line power
