VMWARE_CANNOT_RETRIEVE_VM_MOR_ID with EMC ScaleIO

If you are trying to run/evaluate EMC ScaleIO on “sub-par” servers, aka a homelab, and you get errormessages very early in the deployment, with the error being:
“VMWARE_CANNOT_RETRIEVE_VM_MOR_ID” or something similar.

It might just be because the cloned templates are set up with too many cores to what your hardware actually supports.

MDT LiteTouch WindowsPE x64 dnsmasq

Just a quick note, it works to boot an MDT LiteTouch WinPE x64-image with dnsmasq, using:

menu label ^Boot MDT-bootdisk
linux /memdisk
initrd /winmdtx64.iso
append iso raw

Splunk systemd unit-file for debian Jessie

This one works with Debian Jessie.
Please note that after the first install, or after upgrades you have to start it manually to accept the license.

# editor /lib/systemd/system/splunk.service

[Unit]
Description=Splunk
Wants=network.target
After=network.target

[Service]
Type=forking
RemainAfterExit=yes
ExecStart=/opt/splunk/bin/splunk start
ExecStop=/opt/splunk/bin/splunk stop
ExecReload=/opt/splunk/bin/splunk restart
StandardOutput=syslog

[Install]
WantedBy=multi-user.target

# systemctl enable splunk.service

Vmware Perl SDK on Debian Jessie

The only thing I dislike more than RPM-based distros, is software thats only tested on RPM-based distros.
</fanboi>

Do the following to install VMWare Perl SDK:

#¬†apt-get install libconvert-units-perl libmath-calc-units-perl libnagios-plugin-perl libxml-perl libclass-methodmaker-perl libnet-ssleay-perl libcrypt-ssleay-perl libarchive-zip-perl libdata-dump-perl libsoap-lite-perl libssl-dev –no-install-recommends

Enter “vmware-vsphere-cli-distrib” after extracting the tar-file from vmware, edit “vmware-install.pl” and search for:


if ( direct_command(“cat /etc/*-release | grep -i ubuntu”) || direct_command(“cat /proc/version | grep -i ubuntu”) ) {

Change it to:

if ( direct_command(“cat /etc/*-release | grep -i ubuntu”) || direct_command(“cat /proc/version | grep -i debian”) ) {

 

After running vmware-install.pl, watch as the installer will ruin your package-manager by downloading stuff via CPAN manually.

Thats just lovely. ūüôā

Installing paperless on Debian Jessie

I wanted to test installation of¬†https://github.com/danielquinn/paperless, but the instructions are “somewhat” unclear.
Here I am trying to document the process, so it might be usefull for someone later on.

First, having a requirements.txt is all great and dandy, but saying I need GNU Privacy Guard does not translate to which package, and a link to GPG’s homepage isnt very helpful.
Also,¬†“apt-cache search gpg | wc -l” returns 72 packages.

Alright, enough said – lets do this. ūüôā

Start slow, apt-get all the requirements (hope I got them all….) :

# apt-get install –no-install-recommends git libtiff-tools¬†python3-pip python3-dev¬†libtiff5-dev libjpeg62-turbo-dev zlib1g-dev libfreetype6-dev liblcms2-dev libwebp-dev tcl8.5-dev tk8.5-dev python-tk unpaper imagemagick tesseract-ocr tesseract-ocr-YOURLANGUAGE

Please note the YOURLANGUAGE there, to find your language do this:

$ apt-cache search tesseract-ocr-| sort

# git clone https://github.com/danielquinn/paperless /usr/src/paperless/
# cd /usr/src/paperless/

Copy the example-config, then edit it.
# cp /usr/src/paperless/paperless.conf.example /etc/paperless.conf
You have to change some stuff in the config-file, so do:
# editor /etc/paperless.conf
And edit:
PAPERLESS_PASSPHRASE, just set and forget – this should never ever be changed.
PAPERLESS_CONSUMPTION_DIR, somewhere your service user have access, I just used a subfolder in $HOME.

Then do

#¬†pip3 install –requirement /usr/src/paperless/requirements.txt

(and poff, there goes management via apt. The packages dont¬†exist with the correct versions in Jessie repos anyway, so well… This wouldnt have been pretty anyway.)

 

After that, do the following:

# /usr/src/paperless/src/manage.py migrate

and

# /usr/src/paperless/src/manage.py createsuperuser

 

Finally you run the software by starting the webserver, and the consumer.
First the webserver:
# /usr/src/paperless/src/manage.py runserver 0.0.0.0:8000 &
(Obviously, remember to open tcp/8000)
And the consumer:
# /usr/src/paperless/src/manage.py document_consumer

Then put pdf-files into the consumer-dir and watch some kind of magic happen.

To be honest, I wasn’t that impressed so I ditched the software at this point.
Therefore I doubt this guide will be updated in the future.

Configure Brother DCP-7055W under Debian Jessie

On a fresh machine, do the following:

# apt-get install cups sane sane-utils —no-install-recommends
(Theres two –no, in case wordpress touches the formating)

Surf to

http://support.brother.com/g/b/downloadend.aspx?c=gb&lang=en&prod=dcp7055w_us_eu_as&os=128&dlid=dlf006893_000&flang=4&type3=625

(In case link dont work,¬†go to Brothers support-site, search up your printer, select Linux as OS, and pick the “deb-edition”, then select¬†“Driver Install Tool”)

Right click on “If your download does not start automatically, please click here.”, copy link.

 

Go to server:

$ wget http://download.brother.com/welcome/dlf006893/linux-brprinter-installer-2.0.0-1.gz

(that link might be old when you are reading this)

Then, as root:

# mkdir brotherprint; mv linux*brprinter*.gz brotherprint; cd brotherprint

# gunzip linux-brprinter-installer-*.*.*-*.gz

# bash linux-brprinter-installer-*.*.*-*

Follow the on-screen installation, don’t panic if it can’t find ia32-libs, its going to work great.

When you are prompted for a device URI, choose yes, select 9 (thats input of IP)

When prompted, insert the IP. (DNS does not work…..)

 

When finished, test the scanner by issuing the following command:

# scanimage -T

You should hear your scanner working now. ūüôā

MotionPie Cam in Domoticz with Motion detection

I wanted to try setting up my Raspberry Pi-camera, and I wanted to integrate it with Domoticz.

I did some manual labor for setting up a dedicated IP-cam from scratch, but after searching around I found MotionPie ( https://github.com/ccrisan/motionPie ).
No point re-inventing the wheel, so I loaded it up according to the installation manual, and got it up network-wise.

The following is needed to be configured in order for Domoticz to work:
IP Address: <ipaddress>
Port:<default-is-80>
Username:<blank>
Password:<blank>
ImageURL:picture/1/current/

If you create a dummy switch in Domoticz, you can have motionpie activate that switch using Motion Notifications:
Enable running of commands, and insert the following command:
curl ‘http://<IP-to-domoticz&gt;:8080/json.htm?type=command&param=switchlight&idx=<IDX>&switchcmd=On’
Where <IP-to-domoticz> is self-explanatory, and <IDX> is the ID-number for the switch.
Don’t forget to edit the switch so it’s a motion sensor, and set a custom off-delay.
MotionPie won’t trigger it “off” for you.

MotionPie and custom filenames

I wanted to setup a tiny timelapse-rig using raspberry pi and the official addon-camera.

A quick search returned MotionPie ( https://github.com/ccrisan/motionPie ), and after setting it up using the supplied wiki-pages and some initial configuration I had a feed to watch.

I plugged in a USB-drive (make sure it has a partition and a filesystem MotinoPie can read (ext4 f.ex.)) and under the admin-menu, and “File Storage” you should be able to select the external storage.

In order to create a timelapse you have to save snapshots at regular intervals, this is done under “Still Images”, select “Interval Snapshots” under “Capture Mode” and insert a interval.
Remember 30 pictures per second for a movie equalls 1800 pictures per minute of video.
Dont exagerate your interval, or you will have a very long (and boring?) timelapse.

15s interval over 3 days is 10 minutes of video and 18 000 pictures.

Now the tricky part was that I wanted to create the timelapse outside of MotionPie, and therefore I needed the pictures in sequence, and not using the default file naming.
There was no real legend with variables that I wanted (I wanted to use unix time) Рso some quick googling led me to this handy site ( http://www.cyberciti.biz/faq/linux-unix-formatting-dates-for-display/ ) Рand that site had this handy table:

%FORMAT String Description
%% a literal %
%a locale’s abbreviated weekday name (e.g., Sun)
%A locale’s full weekday name (e.g., Sunday)
%b locale’s abbreviated month name (e.g., Jan)
%B locale’s full month name (e.g., January)
%c locale’s date and time (e.g., Thu Mar 3 23:05:25 2005)
%C century; like %Y, except omit last two digits (e.g., 21)
%d day of month (e.g, 01)
%D date; same as %m/%d/%y
%e day of month, space padded; same as %_d
%F full date; same as %Y-%m-%d
%g last two digits of year of ISO week number (see %G)
%G year of ISO week number (see %V); normally useful only with %V
%h same as %b
%H hour (00..23)
%I hour (01..12)
%j day of year (001..366)
%k hour ( 0..23)
%l hour ( 1..12)
%m month (01..12)
%M minute (00..59)
%n a newline
%N nanoseconds (000000000..999999999)
%p locale’s equivalent of either AM or PM; blank if not known
%P like %p, but lower case
%r locale’s 12-hour clock time (e.g., 11:11:04 PM)
%R 24-hour hour and minute; same as %H:%M
%s seconds since 1970-01-01 00:00:00 UTC
%S second (00..60)
%t a tab
%T time; same as %H:%M:%S
%u day of week (1..7); 1 is Monday
%U week number of year, with Sunday as first day of week (00..53)
%V ISO week number, with Monday as first day of week (01..53)
%w day of week (0..6); 0 is Sunday
%W week number of year, with Monday as first day of week (00..53)
%x locale’s date representation (e.g., 12/31/99)
%X locale’s time representation (e.g., 23:13:48)
%y last two digits of year (00..99)
%Y year
%z +hhmm numeric timezone (e.g., -0400)
%:z +hh:mm numeric timezone (e.g., -04:00)
%::z +hh:mm:ss numeric time zone (e.g., -04:00:00)
%:::z numeric time zone with : to necessary precision (e.g., -04, +05:30)
%Z alphabetic time zone abbreviation (e.g., EDT)

So then it was just a matter of replacing anything under “Image File Name” with “pics/%s” – and everything will be jolly good.
