Papusza – Polish movie (2013) about the life of the gipsys and first gipsy poet

Tuesday, November 4th, 2014

Gipsys (Romani-people)
 as a communities all around mostly Europe has always raised interest during the last few centuries however little is known on their stereotype of living. Gipsys are famous for their illiteracy, for their cheerful temper, wild character and nomadic life-style as well as strong closed community. Gipsys are famous for that they don't have their own writting (even though they have a number of gipsy languages) and because of them Romani, doesn't keep any record of their history and any history or lifestyle of them is only to be found by non-gipsies. Gipsies are famous for being able to steal for their inclination to telling fantastic stories, be involved with fortune-telling, exaggerating facts or telling lies about their private life, they're famous as good virtuosos musicians and good artists. Most of Gipsys are Christian, Muslim or Atheists. The high-level of illiteracy they have makes anyone educated among them to be considered a success in life.

The interesting way of living of Gipsys has triggered many people to create movies, trying to picture Gipsys life-style like Emil Kosturica's Time of the Gipsys.

Yesteday I was invited by Andrea (an ipo-diakonus) in Saint George Dyrvenica Church in the Polish Culture center here in Sofia to see another movie dedicated to Papusza (Bronisława Wajs) – (1908-1987), a famous gipsy who is practically the first (Polish Gipsy Romani) classic poet and singer. The word Papusza in Gipsy language means 'A Doll' – a name given to the future poetess by her mother.
The movie is a great to saw for anyone willing to know more about the history and culture of gipsys in a synthesized form. My interest into Gipsys is because in Bulgaria officially we have about 350 000 Gipsys and I've encounted many gipsys in my life. During my studies in Netherlands, I had the chance to spend quite a lot of time, being in close relations with Bulgarian gipsy family and I was fascinated on how good hearted and primitive truthfulness of gipsys.

Now back to the movie The fact that a gipsy woman could write a beatiful inspired poems and sing so beatiful and most importantly read was almost scandalous! for the post age of World War II and 1960-80s.
Papusza movie is mostly interesting to anyone interested in culturology and antropology as it depicts the Gipsys common lifestyle and for those who already encountered gipsys in their life gives another understanding on why gipsys are who they're and why they choose to live the nomad, poor, uneducated, often careless but joyful and passionable life.

The movie start showing Papusza's mother while still pregnant with the future poetes. In the 1900s when the story goes Roma (Rom meaning man), just like jewish were quite a closed community moving all through the country of Poland or any other country residing using a horse-drawn caravans (tabors) as a moving houses.
Consorting with non-romas (Gadjo's – meaning like the Jewish Goa distinguishment for non jewish) for any reason different than trade was considered unclean. 
However the young poetes had the non-gipsy Wajs surname because according to legend her family used to be touring the great courts of Europe with their harps entertaining kings and aristocrats.


From her birth Papusza was known to be different. A spirit predicted that she would either bring great honor or dishonor to gipsys.
According to the movie she did both. The young Papusza defies her family's wishes and learns to read and write at time,
where almost none gipsy was literate. She is presented stealing a chicken and preseting it to a Jewish store-keeper lady in return for lessons in learning.
Even though her family is strongly again her education (beats her burns her books) she is strunggling to read secretly which later
is shown to have brought supposedly "a curse" on her people.

Papusza meets the Polish poet Jerzy Ficowski in 1949 at a time after being forcefully married to her step-uncle Dionizy Wajs for more than 25 years.
The Gadjo (Ficowski) travels with Wajs caravan for about 2 years as he aims to learn the Romani (Gipsy) language and the gipsy was of life.
He is struck by the beatifulness of Papusza's songs and liking them encourages to continue writting poems.


Later Ficowski returns to Warsaw in 1951 and translates from Gipsy Papusza's verses which broughts Gipsy to a mindset that Papusza reveals their secrets. Later the scandal progresses as Ficowski publishes a monograph book "Polish Gypsies" – a book about the beliefs and moral code of the Roma Gipsy people. Being grieved Papusza's clan takes decision to cast her out.

The movie is amazingly giving "a feel" on the fascinating and simple Gipsy nomad lifestyle during the first and second World War in which they were chased marked and killed by Hitler's Germany just like the Jews. The bitter experience later led to Papusza's creating one of her most famous songs. 


The movie is quite intersting from jumping from time to different stages of Papusza's life not in a specific order but often showing facts backwards etc.
After the end of the war in Poland Communist authorities enforce laws to make Gipsys settle, tryting to ensure them work and job and try to "program" and make part of communist society gipsy kids by using Kindergarden. Romani's a are shown to have problems with authorities and their desperate discontent to go against the country program for settlement of Gipsys, they cannot any more hire the randomly old houses to survive the winter and while unable to survive the harsh Polish winter, they finally settle in attempt to become part of society.


However in the newly built communistic society, they fail to fit well as always considered a second class people, they mourn for their old nomadic vagrant way of people and they fail to integrate to society (pretty much like today). Papusza's spent rest of her life in misery being rejected by both her native Gipsy community for betraying some of gipsys secrets and same time unaccepted by Polish people that continue to consider gipsys inferior.

Richard Stallman explaining Why IPads and Cell Phones are bad for freedom

Wednesday, July 11th, 2012

It is a public secret that Mobile Phones which does us very good and generally makes our daily lifes way easier are also a big enemy to our natural ihnibited freedom. Life has become such that it is almost inevitable to do any business or do a daily simple jobs without using Mobile Phone. There is almost none practically today that has wilfully rejected to use the mobile phone on any basis, almost anyone except some strangers like Richard Stallman and probably few others security freaks.

I've been shocked to find out the Father of Free Software (Richard Mathew Stallman), well known in the hacker dome as RMS does not own and didn't use any mobiles. The concerns he pointed are very much logical and rightful. Owning a mobile is a great security hole in personal privacy (mobile phones can be easily sniffed by Mobile Operators) as well as anyone wearing a mobile can be tracked up to 5 to 2 meters to the exact location where he is based on the mobile phone cells to which the mobile is connected.

Many people are not aware actually of the severeness of the issue of constant tracking of people everywhere through this call "goodies". Many mobile operators are already running a software which is building place behaviour patterns of every user of their mobile network. In other words, as we're used to bring and use the mobile everywhere in automated program is creating a map for each number assigned in some of the mobile operators. The gathered data about our location going habits can then be easily used as a indicator for predicting our future behaviour, bying habits (how many times we go to super-market), how many times we go to cinema, what kind of interests we hold etc. etc.
This combined with Google, account monitoring could possibly create a system similar to the old movies Big Brother, where all people goods and even attitudes or desires is monitored, influenced and controlled ….

The severeness of the future implications of this constant "personal surveillance and tracking device" as Stallman use to call it is very dangerous for our freedoms.

I tried to live without a mobile phone, just like Stallman for about months, and to tell you the truth the world around seems completely different when you decide not to use 'em. The time I lived wihtout a mobile, clearly show me we have come to the point we cannot any more live without GSM. We fall the trap of dependanding the little "talk box" communication for absolutely everything, obviously sacrificing privacy and freedom for convenience.
Mobiles are just one side of the coin, as the non-free software which is ruling the software market and the use of computers puts another treat and takes away many foundamential freedoms we used to have in the less technological world.

Apple as a vendor of software and hardware also denies and breaks our freedom very badly, as the company tracks everyone who owns anything created by apple connected to the internet. Besides that non-free software producers, could change the user software with a press of a button giving them the opportunity to decide what is good and bad for us, leaving us at a state of a helpless dependable users.

The topic of technological little-by-little enslavement, we're going through nowdays and the denying freedoms, we experience while being convinced by companies that we became more free by each next mambo-jambo gadget or by owning the latest smart-phone is very huge and complex but unfortunately underseen in society. I don't understand why, is it due to the low technical skills of mass users is it due to a "not-care what will happen in future" attitude, but obviously people openly discussing or protesting the technologization taking away our freedom is almost zero ….

Here is the video I found in youtube in which Stallman is asked few, questions on Ipads (IBADS) and Mobile Phone use. I believe his short explanation synthesizes the problem quite well ;;;;

I just wonder after you check the video, Would you still accept an Ipad as a birthday gift ? 🙂
Do you still think cell-phones are "good" freedom safe and reliable ?

Color Trick Microsoft and Google use to keep their users loyal and happy unwalfully

Tuesday, June 12th, 2012

Color mind influence has been longly researched. It is researched and there are some findingings on how we people react on colors. This researches are not much known and most of them are not put on the internet (??) One model claiming to have explained how colors influence is called HBDIHerrmann Brain Dominance Instruments.

In the picture beginning of this post, I have presented a quick "Personal Profile" of HBDI on how one think in order to determine in "which colors" one tends to think more ___

In short HBDI model claims to explain how people think in another model.
My personal view of it is it is like most science nowdays more based on faith than on a clearly conducted scientific research and facts. We know pretty well many people tried to explain how brain operates and many people give models to explain it however none of the models could grasp in completeness the complexity of human brain. Hence Businessman people who use this model in their daily life and they push it to us has put the model in action not that they know it is working but rather they believe it does .., Saying this few words as introduction I will contninue onwards to explain you about HBDI as in the business world it is considered as a "Strategic Asset" for a company success. Hence the use of richest companies of the model has a serious impact on us the common people and unknowing (uninformed) computer users.

Some of the companies who integrated the HBDI to their models we all know are of course not strangely Microsoft and Google

Below I present you a picture showing the HBDI The Whole Brain Model |||

HBDI The whole brain model

Next I show you Microsoft Windows OS worldly "infamous" flag |||

Microsoft Windows OS Flag

You can see for yourself the basic color from HBDI WHOLE brain model are integrated in the Microsoft flag, only the order of colors present and the color gamma is different;;;;

The basic colors in HBDI model to explain how human brain works is separated in 4 segments as you can see from above screenshot. There are a number of tests one can do to determine what is his exact HBDI profile, and in abstract terms in which kind of colors he prefers to think.

There are a whole "army" of people involved into this sect like philosophy (I call it philosophy as surely every model that tries to explain everything is doomed to fail it is the nature in which God created the universe so complex and he put us be part of it and not controllers of it that any Universal model trying to explain it has never succeeded so far. The HBDI has some fruits for the only reason it is believed to work well by the people with money.

As you see in the colors HBDI claims there are 4 segments corresponding to four basic colors

  • BLUE
  • RED

Each of the colors is an indicator on how the person tends to think the BLUE people as HBDI practicioners (believers) calls them are —

Analytical, Fact Based, Logal, Quantitative

The YELLOW oriented people are claimed to be —

Holistic, Intuitive, Integrating, Synthesizing

The GREEN ones in model terms are interested in —

Organizing, Sequentiality, Planning, Detailizing facts

Finally the RED Ones are said to be —

Interpersonal, Feeling based, Kinesthetic, Emotional

Now as you can understand this model though it looks like promising is based on a philosophy which rejects the existing of spirit realm God Angels or good or evil. It claims everything we're are or we want to be can be achieved following the HBDI to develop your own brain.

This model as every human made model however does reject the fact that besides internal factors and brains we're put into external environment most of which we cannot control and therefore even if we try our best to have certain goals and complete them the external uncontrolled facts can be a reason to stop us to complete our goals.

Now back to my point, that Google, Microsoft and probably many other products and physical goods are heavily using the HBDI color scheme ;;;
Here is the Google Inc. Logo the color trait of HBDI is there:

Google Search Engine Logo and HBDI 4 colors embedded

For those doubting that Google Inc. and Microsoft Inc. are along the false believers of HBDI color scheme brain ideology I present below the Logo of Google Web Browser =- Google Chrome

Google Web Chrome Browser Logo 4 colors HBDI microsoft flag

It is evident 4 colors used as a main ones in the HBDI tool are present in Google Chrome just like in Microsoft Windows logo flag, the only difference is in the order of colors.
Also it is interesting the name Chrome that Google Chrome took is most likely taken from Aldous Huxley's – Brave New World (A book depicting a short future highly conditioned society) , the book story line goes around a society programmed to do the things they do.

I assume it is very likely that Google's founders Sergey Brin or some of their subordinate working for Google are very much into the idea of conditioning people just like in the book and this is most likely the reason they choose the Chrome as a title for Google's browser ,,,

The 4 Colors from HBDI yellow, green, blue, red are embedded also in the google .ico file (the little icon showing in browser URL bar), below is a screenshot of a tab where google is opened showing the .ico image:

Google Icon 4 colors Linux Debian Epiphany Browser tab screenshot

Do you remember the good old Windows XP start button, have you noticed the Windows flag embedded in it, if not let me show you;;;

Microsoft Windows XP Start Button and HBDI 4 colors scheme

But wait the Windows flag placed on the left bottom of Ms Windows-es is not only on XP it is also on Windows 3.11 cover, Winblows 98, Vista, Windows 2003, Windows 2007 and actually all the M$ operating systems ever produced since the very early days M$ become a top OS producer :::

Windows 3.11 Operating system logo flag

Microsoft Windows 95 4 colors flag and blue sky

Here is also the 4 colored (a bit like Nazi like looking) flag on M$ Win-doze 7 |||

MS Windows 7 start Menu m$ windows well known flag

Also the Microsoft Flag is positioned on the bottom left screen on purpose. It is well known fact that most of the world (except Arabic) are used to read the text from Left to Right

, therefore it is natural for our eyesight to look for the text on the left side. I just wonder why they placed the START on the bottom and not on top. It is natural we read text and books from the most top to the most bottom ,,,.,

Even Apple Computers nowdays Macs has most likely used the HBDI as the main 4 colors and some gamma from rainbow colors are present on their Classical Apple Computer logo

Old Apple Computer/s logo colors of rainbow 4 hbdi colors are there

Makes me wonder if Jobs employed the HBDI model in his company. Well what is the reason for people loving so much this rainbow colors combination. If we think for a second outside of HBDI's brainwashing ideology for what each color would stand for. Well it is simple is comes from our young years most of the people between age 2 and 50 years has been more or less exposed to the so colorful Kids Cartoons, which are all so colorfully painted. Since our very early age we've placed in us a love for colorfulness outlook (well again not all of us for example I prefer less colors, I'm sure there are plenty of people who don't like the heavy colors we see in almost everywhere around us).

The problem with this 4 colors use on purpose and all this unnatural color placing everywhere is that it is unnatural and not in good synergy with our surrounding natural environment. Therefore I personally think using a colorful color paintings on everywhere in both computer programs and the physical world plays us a bad joke and is one of the reasons so many people are on the virge to get crazy nowdays and many have already had already cracked out.

It is my firm believe more and more people should be educated on the harm of HBDI and the fact that, we're forced to 'live it' unwilfully every day by using even as "simple things" as computers and daily technology or buying food in the super market ,,,

How to take area screenshots in GNOME – Take quick area selection screenshots in G* / Linux and BSD

Thursday, March 15th, 2012

Quick Area screenshot in GNOME how to make quick area selection screenshots in Linux and FreeBSD gnome-screenshot shot

Often when, you do something on your PC, you need to make a quick screenshot of a screen area.. Yes GNOME's feature to take complete screenshots of Screen with Print Screen SysRQ and consequential picture edit with GIMP is one way, but this is far away from quick. This method to chop out of a complete display screenshot usually takes from 40 secs to 1 minute to properly cut and save a selection of the whole picture.
Another common use, that I love in GNOME is the ALT + Print Screen SysRQ key combination. alt+ print scr sysrq is handy while taking a single window screenshot is desired. Anyways often you only need to make a screenshot of a tiny area of the screen. Many people might think this is not possible currently in GNOME, but they will be wrong as there are no impossible but hard things to achieve on Linux / FreeBSD 😉

There are at least two ways using a predefined command for taking quick area screen snapshot.

1. Taking quick area screenshot by using ImageMagick's import command

To use import you will need to have installed ImageMagickswiss army knife of command line image manipulation 😉
For area screenshot with import, press ALT+F2 and type inside Run Application box:

Screenshot GNOME run application GNU / Linux Debian ImageMagick import area screenshot

import -frame screenshot.png

Now make the selection of the exact screen area you would like to screeshot in file screenshot.png
Note that screenshot.png file will be saved by default in your home directory as it is read from $HOME shell variable:

hipo@noah:~$ echo $HOME/home/hipo
hipo@noah:~$ ls -al screenshot.png
-rw-r--r-- 1 hipo hipo 4950 Mar 14 21:11 screenshot.png

You see my $HOME equals /home/hipo, therefore screenshot.png just grabbed is saved in there.

One downside of taking the screenshot with import is that picture snapshot is not further edittable, if it has to be further processed with GIMP or some other graphic editor program.

In the screenshot, below I show you one screen area of my XMMS taken with import -frame screenshot.png cmd:

XMMS Screen Area Screenshot import screenshot

Trying to open the screenshot.png, file with GIMP displays the following error in GIMP:

PNG image message PNG the file specifies offset that caused the layer to be positioned outiside image GIMP screenshot

Not all area snapshots taken with import -frame, create this issue sometimes screenshots are opening in GIMP but only area of the screenshot.png is visible in gimp.

Thanksfull, there is work around to this issue by converting the import generated PNG format picture to JPEG with ImageMagick's convert and then edit the .JPEG with GIMP etc.:

hipo@noah:~$ convert screenshot.png screenshot.jpg

Hence to permanently work around it, in case you intend to apply (GIMP modifications), once area snapshot is made instruct import to save its output picture in .jpeg, e.g.:

hipo@noah:~$ import -frame screenshot.jpeg

2. Taking quick area screenshot using gnome-screenshot cmd

Once again invoke the GNOME command Launcher by pressing Alt+F2 (holding alt and pressing F2) and type in the launch box:

gnome-screenshot -a

gnome-screenshot Run Application in GNOME 2.30 on Debian GNU / Linux

Below is a small area from my desktop, chopped with gnome-screenshot 🙂

GNOME desktop area chop screenshot with gnome-screenshot on my home Debian Linux

You see on above screenshot a tiny (picture) icon one of the greatest, if not the greatest bulgarian saint – saint John of Rila. St. John's lived as hermit for many years in Rila mountain and by God's grace possessed incorruptable body. His incorruptable body is still kept and can be venerated in Rila Monastery. The monastery is located 160 km from Bulgaria's capital city Sofia

St. Johns first Bulgarian established monastery Rila Monastery is currently the biggest functioing monastery in Bulgaria. The saints monastery is considered one of the most holy places in Bulgaria. If you have a travel or plan a holiday in Bulgaria, I warmly recommend you go there and venerate the saint incorruptable relics.

3. Binding keys to allow quick area screenshot taking with gnome-screenshot in GNOME

This configuration is for GNOME 2.x and is tested to work on my Debian (Squeeze 6.0), GNOME ver. 2.30.2, it should work in earlier Ubuntu versions shipped with GNOME 2.2.xx too. As I've red on the Internet it works well with Ubuntu 10.10Binding a key for screenshot area grab, should be working properly also on any GNOME 2.2.x supporting OS, including the BSD family OSes (FreeBSD, OpenBSD, NetBSD)

a) setting gnome-screenshot key binding for interactive screenshot area grab

Navigate the mouse cursor to GNOME main menus panel in left top, where you see (Applications, Places, System).
Therein use menus:

System -> Preferences -> Keybord Shortcuts -> Add ->

Alternatively if you prefer you can directly invoke the Keyboard Shortcuts configuration with command:

hipo@noah:~$ gnome-keybinding-properties

Further on, assign a shortcut by filling in something like:

name: grab-screen-area
command: gnome-screenshot -i -a

GNOME add keyboard shortcut map key for area interactive screenshot

press Apply and next map a key to the new defined key binding:

GNOME add keyboard shortcut map key

Under the Shortcut column click on Disabled and assign some key combination to invoke the cmd for example Ctrl+F4

The command gnome-screenshot -i makes gnome-screenshot, show interactive make screenshot dialog like the one in below screenshot.

GNOME screenshot interactive screenshot select area grab shot

b) creating gnome-screenshot -a area screenshot key binding for quick area screenshots "on the fly"

The procedure is precisely the same as with adding interactive screenshot; Under Keyboard Shortcuts GNOME config assign new key binding by pressing Add button and adding:

name: grab-screen-area1
command: gnome-screenshot -a

Once again in Shortcut column in line starting with grab-screen-area1 add your desired key switch. I personally like Ctrl+Print Screen SysRQ as it is close to the default GNOME key combination assigned for taking screenshot for a Windows Alt+Print SysRq

It was logical, that this key binding should work and a direct selection mouse cursor to appear once Alt+Print SysRQ is pressed, however for some reason this is not working (hmm, maybe due to bug) ??

Thanksfully it is always possible to substitute the just assigned gnome-screenshot -a key binding with import -frame /home/hipo/Desktop/screenshot.png

If you have followed literally my article so far and you did tried to place a bind for gnome-screenshot -a, modifty grab-screen-area1 to be something like:

name: grab-screen-area1
command: import -frame /home/hipo/Desktop/screenshot.png

Where modify the path /home/hipo/Desktop/screenshot.png, to wherever you prefer the region screep capture to be stored.

c) bind keys for delayed screenshot

This also a handy binding, especially if you every now and then need to make screenshots of screen with a few secs interval.
Add one more keyboard shortcut;

name: grab-screen-area2
command: gnome-screenshot -d 5

Assign a key to make a screenshot of the active display after a delay of 5 seconds. I prefer Ctrl+F5

Onwards every time you would like to make an area screenshot, just use the defined keys:

Ctrl+F4 - will prompt you interactively for the precise type of screenshot you would like to take
Ctrl+Print SysRQ - will prompt you for a direct area to select and once selected will immediately screenshot it
Ctrl+F5 - would do delayed screenshot of entire screen after a delay of 5 seconds

4. Adding border and drop shadow effects with gnome-screenshot Actually, there is plenty of interesting things to do with Screenshots which I never thought were possible.
While reading gnome-screenshot's man page, I've stumbled to an interesting argument:

-e, --effect=EFFECT,
Add an effect to the outside of the screenshot border. EFFECT can be ``shadow'' (adding drop shadow), ``border'' (adding
rectangular space around the screenshot) or ``none'' (no effect). Default is ``none''.

This would have been a nice feature but as of time of writting this article, untofrtunately it is not working in GNOME 2.30.2. I'm not sure if this is a local Debian bug, however I suspect on other Linux distributions with different GNOME build configuration, this features might be working well. My guess here is drop shadow effect and border effect are not working because, gnome-screenshot was compiled without (support for ImageMagick?).
Anyways the way the feature is supposed to be work is by invoking commands:

hipo@noah:~$ gnome-screenshot --border-effect=shadow
hipo@noah:~$ nome-screenshot --border-effect=border

The same basic effects, are also available through GIMP's menus:

Image -> Effects

5. Setting default behaviour of gnome-screenshot in gconf-editor GConf (Gnome config registry db)

Experienced, GNOME users should already know about the existence of gconf-editor and the gnome registry database. For those who have don't, coming from MS-Windows background gconf-editor is GNOME (graphical environment) equivalent to Microsoft Windows registry regedit command

gconf-editor can be used to atune the way the screenshots are taken by default. To do so, launch gconf-editor cmd and follow to sub-structure:

/ -> apps -> gnome-screenshot

gconf-editor GNOME screenshot border effect none default gnome-screenshot gnome behaviour

The settings in above screenshot are configurations which are used by default by gnome-screenshot, right after install.
You can play with the options to change the default way PrintScreen SysRQ key press will take screenshots.
Here is one example for changing the gnome-screenshot default GNOME behaviour:

GConf Editor GNOME screenshot, border effect drop shadow and include border option set on Linux Debian

As you can see in above screenshot, I've changed my default gnome-screenshot snap taking to include a drop shadow effect:
Name | Value
border_effect | shadow include_border | (tick on)
last_save_directory | file://home/hipo/Desktop

As you see you can also control, where by default gnome-screenshot will save its screenshots, by default, its saved in $HOME/Desktop
. If you prefer some custom directory to only contain Screenshots taken for instance $HOME/Screenshots, create the directory:
hipo@noah:~$ mkdir ~/Screenshots

and then change the value for last_save_directory gconf var:

last_save_directory | file://home/hipo/Screenshots

Once settings are applied screenshots with Print Screen SysRQ key will be made with Shadow Border effect and saved in /home/hipo/Screenshots

Strangely enough, changing gnome-screenshot default screenshotting values to include screenshot effects like drop shadow or screenshot border effect works just fine.
Even though gnome-screenshot –border-effect=shadow and gnome-screenshot –border-effect=border doesn't directly affect the current screenshot to be made, I've later noticed writting this two commands in the gnome-terminal, does change the border settings for gconf-editor screenshot border.

If you enjoyed, this article and you intend to become "a professional screnshotter" :), you might also enjoy my two other articles:

Happy screenshotting 😉

Fix vnstat error “eth0: Not enough data available yet.” on Debian GNU / Linux

Monday, November 21st, 2011

Vnstat GNU Linux console terminal traffic statistics logo

After installing vnstat to keep an eye on server IN and OUT traffic on a Debian Squeeze server. I used the usual:

debian:~# vnstat -u -i eth0

In order to generate the initial database for the ethernet interface used by vnstat to generate its statistics.

However even though /var/lib/vnstat/eth0 got generated with above command statistics were not further generated and trying to check them with command:

debian:~# vnstat --days

Returned the error message:

eth0: Not enough data available yet.

To solve the eth0: Not enough data available yet. message I tried completely removing vnstat package by purging the package e.g.:

debian:~# apt-get --yes remove vnstat
debian:~# dpkg --purge vnstat

Even though dpkg –purge was invoked /var/lib/vnstat/ refused to be removed since it contained vnstat’s db file eth0

Therefore I deleted by hand before installing again vnstat:

debian:~# rm -rf /var/lib/vnstat/

Tried installing once again vnstat “from scratch”:

debian:~# apt-get install vnstat

After that I tried regenerating the vnstat db file eth0 once again with vnstat -u -i eth0 , hoping this should fix the error but it was no go and after that the error:

debian:~# vnstat --hours
eth0: Not enough data available yet.


I checked in Debian bugs mailing lists and I found, some people complaining about the same issue with some suggsetions on how the error can be work arouned, anyways none of the suggestions worked for me.

Being irritated I further removed / purged once again vnstat and decided to give it a try by installing vnstat from source
As of time of writting this article, the latest stable vnstat version is 1.11 .
Therefore to install vnstat from source I issued:

debian:~# cd /usr/local/src
debian:/usr/local/src# wget
debian:/usr/local/src# tar -zxvvf vnstat-1.11.tar.gz
debian:/usr/local/src# cd vnstat-1.11
debian:/usr/local/src/vnstat-1.11# make & make all & make install
debian:/usr/local/src/vnstat-1.11# cp examples/vnstat.cron /etc/cron.d/vnstat
debian:/usr/local/src/vnstat-1.11# vnstat -u -i eth0
Error: Unable to read database "/var/lib/vnstat/eth0".
Info: -> A new database has been created.

As a last step I put on root crontab to execute:

debian:~# crontab -u root -e

*/5 * * * * /usr/bin/vnstat -u >/dev/null 2>&1

This line updated vnstat db eth0 database, every 5 minutes. After the manual source install vnstat works, just fine 😉

Fix to mail forwarding error “Received-SPF: none ( domain at maildomain does not designate permitted sender hosts)

Tuesday, October 18th, 2011

I’m Configuring a new Exim server to relay / forward mail via a remote Qmail SMTP server
Even though I configured properly the exim to forward via my relaying mail server with host, still the mail forwarding from the Exim -> Qmail failed to work out with an error:

Fix to mail forwarding error "Received-SPF: none ( domain at maildomain does not designate permitted sender hosts)

I pondered for a while on what might be causing this “mysterous” error just to realize I forgot to add the IP address of my Exim mail server in the Qmail relay server

To solve the error I had to add in /etc/tcp.smtp on my Qmail server a record for my Exim server IP address xx.xx.xx.xx, like so:

debian-server:~# echo 'xx.xx.xx.xx:allow,RELAYCLIENT="",QS_SPAMASSASSIN="0"' >> /etc/tcp.smtp

The QS_SPAMASSASSIN=”0″ as you might have guessed instructs Qmail not to check the received mails originating from IP xx.xx.xx.xx with spamassassin.

Finally on the Qmail server to load up the new tcp.smtp settings I had to rebuild /etc/tcp.smtp.cdb and restart qmail :

– reload qmail cdb

linux-server:/var/qmail# qmailctl cdb
Reloaded /etc/tcp.smtp.
- restart qmail

linux-server:/var/qmail# qmailctl restart
Restarting qmail:
* Stopping qmail-smtpdssl.
* Stopping qmail-smtpd.
* Sending qmail-send SIGTERM and restarting.

How to make pptp VPN connection to use IPMI port (IPKVM / Web KVM) on Debian Linux

Wednesday, July 27th, 2011

If you have used KVM, before you certainly have faced the requirement asked by many Dedicated Server Provider, for establishment of a PPTP (mppe / mppoe) or the so called Microsoft VPN tunnel to be able to later access via the tunnel through a Private IP address the web based Java Applet giving control to the Physical screen, monitor and mouse on the server.

This is pretty handy as sometimes the server is not booting and one needs a further direct access to the server physical Monitor.
Establishing the Microsoft VPN connection on Windows is a pretty trivial task and is easily achieved by navigating to:

Properties > Networking (tab) > Select IPv4 > Properties > Advanced > Uncheck "Use default gateway on remote network".

However achiving the same task on Linux seemed to be not such a trivial, task and it seems I cannot find anywhere information or precise procedure how to establish the necessery VPN (ptpt) ms encrypted tunnel.

Thanksfully I was able to find a way to do the same tunnel on my Debian Linux, after a bunch of experimentation with the ppp linux command.

To be able to establish the IPMI VPN tunnel, first I had to install a couple of software packages, e.g.:

root@linux:~# apt-get install ppp pppconfig pppoeconf pptp-linux

Further on it was necessery to load up two kernel modules to enable the pptp mppe support:

root@linux:~# modprobe ppp_mppe
root@linux:~# modprobe ppp-deflate

I’ve also enabled the modules to be loading up during my next Linux boot with /etc/modules to not be bother to load up the same modules after reboot manually:

root@linux:~# echo ppp_mppe >> /etc/modules
root@linux:~# echo ppp-deflate >> /etc/modules

Another thing I had to do is to enable the require-mppe-128 option in /etc/ppp/options.pptp.
Here is how:

root@linux:~# sed -e 's$#require-mppe-128$require-mppe-128$g' /etc/ppp/options.pptp >> /tmp/options.pptp
root@linux:~# mv /tmp/options.pptp /etc/ppp/options.pptp
root@linux:~# echo 'nodefaultroute' >> /etc/ppp/options.pptp

In order to enable debug log for the ppp tunnel I also edited /etc/syslog.conf and included the following configuration inside:

root@linux:~# vim /etc/syslog.conf
news.none;mail.none -/var/log/debug
root@linux:~# killall -HUP rsyslogd

The most important part of course is the command line with ppp command to connect to the remote IP via the VPN tunnel ;), here is how I achieved that:

root@linux:~# pppd debug require-mppe pty "pptp --nolaunchpppd" file /etc/ppp/options.pptp user My_Dedi_Isp_Given_Username password The_Isp_Given_Password

This command, brings up the ppp interface and makes the tunnel between my IP and the remote VPN target host.

Info about the tunnel could be observed with command:

ifconfig -a ppp
ppp0 Link encap:Point-to-Point Protocol
inet addr: P-t-P: Mask:
RX packets:7 errors:0 dropped:0 overruns:0 frame:0
TX packets:12 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:3
RX bytes:70 (70.0 B) TX bytes:672 (672.0 B)

One more thing before I could finally access the IPMI’s web interface via the private IP was to add routing to the private IP address via the tunnel other side IP address:

# P-t-P IP address
ip route add dev ppp0

Now logically one would thing the Web interface to login and use the Java Applet to connect to the server would be accessible but no IT wasn’t !

It took me a while to figure out what is the problem and if not the guys in ##networking helped me I would never really find out why and were inaccessible.

Strangely enough both ports 80 and 443 were opened on and it seems like working, however though I can ping both and there was no possible way to access with TCP traffic.

Routing to the Microsoft Tunnel was fine as I’ve double checked all was fine except whether I tried accessing the IPMI web interface the browser was trying to open the URL and keeps opening like forever.

Thanksfully after a long time of futile try outs, a tip was suggested by a good guy in freenode nick named ne2k

To make the TCP connection in the Microsoft Tunnel work and consequently be able to access the webserver on the remote IPMI host, one needs to change the default MTU set for the ppp0 tunnel interface.
Here is how:

ip link set ppp0 mtu 1438

And tadam! It’s done now IPKVM is accessible via or web interface. Horay ! 🙂
