Ancient Christian Coptic Oriental Orthodox icons – The reason for asymmetric body members in early Christian iconography

Monday, July 30th, 2012

While checking some information on Coptic Eastern Oriental faith, I've stumbled upon a very beautiful (and unique) ancient Orthodox Christian icon depicting Saint Menas and our saviour the Lord Jesus Christ, below is the very beautiful icon

Saint Mena (Sv. Mina) and The Lord Jesus Christ icon from 6th century

Saint Mena (Sv. Mina) and The Lord Jesus Christ icon from 6th century

As you can see the iconography is very interesting, the images differ from modern day iconography the portraits are not looking so serious but looks like "childish". This childish forms and faces on the early Christian iconography is not accidental; it expresses the childish like pure faith our Christian devoted ancestors had. This early Christian faith and spiritual life icon is obviously in conjunction with our Saviour Jesus Christ words as red in the Gospel according to Matthew:
 

At that time the disciples came to Jesus, saying, "Who then is greatest in the kingdom of heaven?" Then Jesus called a little child to Him, set him in the midst of them, and said, "Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven. Therefore whoever humbles himself as this little child is the greatest in the kingdom of heaven. Whoever receives one little child like this in My name receives Me.

Matthew 18:1-5

This icon as well as the early Christian icons are very different from nowdays iconography probably for reason;
the images difference, the seriousness and the lack of brightness in the faces of nowdays iconography is a clear sign of the great decay of both Orthodox Christian as well as the down-fall of spiritual life worldly.
I've seen similar childish looking image icons in some Bulgarian ancient relics museums in my child years and always thought the depictions are so kiddish because iconographers of that time did not have the painting knowledge and skills to draw better ones.
Now as I know Christianity much better than then, I understand my previous assumption for the reason of the kiddish looking images is wrong.
Saint Mena (Sv. Mina) and The Lord Jesus Christ icon from 6th century

Very interesting in the early Christian iconography are the shapes. If you take a close look to above icon, you will notice the disparity of the two body members; the hands, head and eyes are unusually big. My guess for the lack of correspondence of body members is the attempt of early iconographers to put accent on most important members of our bodies;

- The head (holding the mind and thoughts of the saints)
- The hands through which the daily food is raised and the eyes through which the world is comprehended are much bigger than in a real person portrait.
- The mouth which is almost the size of the eyes; obvious reference that for early Christian contemplating was much more precious (important) thing, than speech.
This is also in accordance with the New Testament holy scriptures which says like so concerning the tongue:
 

8 But no one can tame the tongue; it is a restless evil and full of deadly poison.
9 With it we bless our Lord and Father, and with it we curse men, who have been made in the likeness of God;
10 from the same mouth come both blessing and cursing. My brethren, these things ought not to be this way.
11 Does a fountain send out from the same opening both fresh and bitter water?
12 Can a fig tree, my brethren, produce olives, or a vine produce figs?
Nor can salt water produce fresh.

Notice also the Halos of the two saints, the size of the halos is almost one third of the whole body of the saints. The Gospel hold by our and all humanity Saviour Jesus Christ is also enormous sized; corresponding almost the height of the arm of Christ on the icon.
The size of the Gospel stresses out the importance of the Holy Bible writtings for early Christians. Nowdays the size of Gospels or Holy Bible especially among protestant Churches "tradition" is becoming smaller and smaller following the spirit of the time proclaiming mobility …

Today the iconography Orthodox Christian "school" has severely changed and the icon images are much more complicated than in ancient times.
The complication of images and elements on Orthodox Icons is a "mirror" of the internal complicated world of us modern-time Christians. This over-complication of our internal spiritual world, does separate us from God instead of uniting us as it is well known in Holy Orthodox Christian tradition God is best known through simplicity and pureness in life thoughts and actions.

The Coptic Oriental Orthodox Church is the only Church, where there is still iconographers drawing in the style of the ancient times childish looking icons. The reason Copts preserved this ancient iconography is that they have conservated big portion of the ancient faith rejecting the decisions of all 7 Orthodox Ecumenical Church Councils. Copts still accept only ecumenical council decisions up to the III-rd ecumenical council. This is also the reason why Eastern Oriental Orthodox Christians are considered not in official communion with the rest of Eastern Orthodox Churches. I had the opportunity by God's grace to meet an Coptic Orthodox Christian (a guy called Baky); From what I've seen and experienced within the few months with Baky my conclusion is Coptic Orthodox layman faith is much stronger than the one in most of other Orthodox Christians I know. The official standpoint of our Eastern Orthodox Church concerning the copts are that they're in heresy and not really orthodox. I'm not sure if this is really true, since I have spend few months with this Coptic Christian brother this autumn and winter and from what I've seen and heard as well as researched on coptic Orthodox it seems their overall Church teaching, Holy Liturgies and everything is very much orthodox (with very little service and faith differences). Here are few beautiful Coptic Orthodox Christian icons still being drawn in the spirit of early days Christianity.

How to convert OGG Vorbis .ogg to MP3 on GNU / Linux and FreeBSD

Friday, July 27th, 2012

I’ve used K3B just recently to RIP an Audio CD with music to MP3. K3b has done a great job ripping the tracks, the only problem was By default k3b RIPs songs in OGG Vorbis (.ogg) and not mp3. I personally prefer OGG Vorbis as it is a free freedom respecting audio format, however the problem was the .ogg-s cannot be read on many of the audio players and it could be a problem reading the RIPped oggs on Windows. I’ve done the RIP not for myself but for a Belarusian gfriend of mine and she is completely computer illiterate and if I pass her the songs in .OGG, there is no chance she succed in listening the oggs. I’ve seen later k3b has an option to choose to convert directly to MP3 Using linux mp3 lame library this however is time consuming and I have to wait another 10 minutes or so for the songs to be ripped to shorten the time I decided to directly convert the existing .ogg files to .mp3 on my (Debian Linux). There are probably many ways to convert .ogg to mp3 on linux and likely many GUI frontends (like SoundConverter) to use in graphic env.

SoundConverter Debian GNU Linux graphic GUI environment program for convertion of ogg to mp3 and mp3 to ogg, convert multiple sound formats on GNU / Linux.

I however am a console freak so I preferred doing it from terminal. I’ve done quick research on the net and figured out the good old ffmpeg is capable of converting .oggs to .mp3s. To convert all mp3s just ripped in the separate directory I had to run ffmpeg in a tiny bash loop.

A short bash shell script 1 liner combined with ffmpeg does it, e.g.;

for f in *.ogg; do ffmpeg -i "$f" "`basename "$f" .ogg`.mp3"; done.....

The loop example is in bash so in order to make the code work on FreeBSD it is necessery it is run in a bash shell and not in BSDs so common csh or tcsh.

Well, that’s all oggs are in mp3; Hip-hip Hooray ;)

How to convert PDF to DOC on Microsoft Windows XP, MS Windows 7, Win Vista convert PDF to MS DOC 2003, ABBYY Covert Page
I had to convert Adobe PDF file to Microsoft Word ( .doc) file on Microsoft Windows OS for a friend. There is plenty of software available to convert PDF to DOC on Windows, as well as few web-site services claiming to convert correcly PDF to DOC. Converting PDF to DOC is easy and can be done with Open Office, however the reverse process is a real pain in the ass. I tried a dozen of free web serviecs to convert an ancient Latin writting PDF to DOC but none of them couldn’t properly convert it. Failing with the web services as a tool to convert, I’ve turned to seeking a tool that will do the trick. After trying few PDF to DOC converters which failed to produce a properly structed edittable DOC from the PDF file, I’ve come across ABBYY PDF Transformer 2.0. Abbyy PDF Transformer finally did it …

I’ve tried hard to look for a free software good PDF to DOC converter alternative for Windows but it seems as of time of writing this post there is no GPLed free software that does properly convert PDFs to MS WORD DOC ….

Using Abbyy PDF Transformer 2.0 is a piece of cake all I had to do is select the PDF file (pressing Open PDF) and then click on Convert (in right bottom corner). Below is a shot of Abby PDF transformer in action.

30 years anniversary of the first mass produced portable computer COMPAQ Grid Compass 1011

Thursday, July 19th, 2012

Grid Notebook Big screen logo

Today it is considered the modern laptop (portable computers) are turning 30 years old. The notebook grandparent is a COMPAQGRiD Compass 1011 – a “mobile computer” with a electroluminescent display (ELD) screen supporting resolution of 320×240 pixels. The screen allowed the user to use the computer console in a text resolution of 80×24 chars. This portable high-tech gadget was equipped with magnesium alloy case, an Inten 8086 CPU (XT processor) at 8Mhz (like my old desktop pravetz pc ;) ), 340 kilobyte (internal non-removable magnetic bubble memory and even a 1,200 bit/s modem!

COMPAQ Grid Compass considered first laptop / notebook on earthy 30 anniversary of the portable computer

The machine was uniquely compatible for its time as one could easily attach devices such as floppy 5.25 inch drives and external (10 Meg) hard disk via IEEE-488 I/O compatible protocol called GPiB (General Purpose instrumental Bus).

First mass prdocued portable computer laptop grid COMPAQ 11011 back side input peripherals

The laptop had also unique small weight of only 5 kg and a rechargable batteries with a power unit (like modern laptops) connectable to a normal (110/220 V) room plug.

First notebook in World ever the COMPAQ grid Compass 1101,br />
The machine was bundled with an own specificly written OS GRiD-OS. GRID-OS could only run a specialized software so this made the application available a bit limited.
Shortly after market introduction because of the incompitablity of GRID-OS, grid was shipped with MS-DOS v. 2.0.
This primitive laptop computer was developed for serve mainly the needs of business users and military purposes (NASA, U.S. military) etc.

GRID was even used on Space Shuttles during 1980 – 1990s.
The price of the machine in April 1982 when GriD Compass was introduced was the shockingly high – $8150 dollars.

The machine hardware design is quite elegant as you can see on below pic:

 COMPAQ grid laptop 1101 bubbles internal memory

As a computer history geek, I’ve researched further on GRID Compass and found a nice 1:30 hour video telling in detailed presentation retelling the history.

Shortly after COMPAQ’s Grid Compass 1011′s introduction, many other companies started producing similar sized computers; one example for this was the Epson HX-20 notebook. 30 years later, probably around 70% of citizens on the globe owns a laptop or some kind of portable computer device (smartphone, tablet, ultra-book etc.).

Most of computer users owning a desktop nowdays, owns a laptop too for mobility reasons. Interestengly even 30 years later the laptop as we know it is still in a shape (form) very similar to its original predecessor. Today the notebook sales are starting to be overshadowed by tablets and ultra-books (for second quarter laptop sales raised 5% but if compared with 2011, the sales rise is lesser 1.8% – according to data provided by Digital Research agency). There are estimations done by (Forrester Research) pointing until the end of year 2015, sales of notebook substitute portable devices will exceed the overall sales of notebooks. It is manifested today the market dynamics are changing in favour of tabets and the so called next generation laptopsULTRA-BOOKS. It is a mass hype and a marketing lie that Ultra-Books are somehow different from laptops. The difference between a classical laptop and Ultra-Books is the thinner size, less weight and often longer battery use time. Actually Ultra-Books are copying the design concept of Mac MacBook Air trying to resell under a lound name.
Even if in future Ipads, Android tablets, Ultra-Books or whatever kind of mambo-jambo portable devices flood the market, laptops will still be heavily used in future by programmers, office workers, company employees and any person who is in need to do a lot of regular text editting, email use and work with corporative apps. Hence we will see a COMPAC Grid Compass 1011 notebook likes to be dominant until end of the decade.

Installing XMMS on Debian Squeeze from a Package / Installing XMMS on Debian – the debian way

Tuesday, July 17th, 2012

installing xmms on debian squeeze linux playing free software song green skin screenshot

I use Debian Linux for my desktop for quite some time; Even though there are plenty of MP3 / CD players around in Debian, I’m used to the good old XMMS, hence I often prefer to use XMMS to play my music instead of newer players like RhythmBox or audacious.
Actually audacious is not bad substitute for XMMS and is by default part of Debian but to me it seems more buggy and tends to crash during playing some music formats more than xmms ….

As most people might know, XMMS is no longer supported in almost all modern Linux distributions, so anyone using Debian, Ubuntu or other deb derivative Linux would have to normally compile it from source.
Compiling from source is time consuming and I think often it doesn’t pay back the effort. Thanksfully, though not officially supported by Debian crew XMMS still can be installed using a deb xmms prebuilt package repository kindly provided by a hacker fellow knuta.

Using the pre-build deb packages, installing xmms on new Debian installs comes to:

debian:~# echo 'deb http://www.pvv.ntnu.no/~knuta/xmms/squeeze ./' >> /etc/apt/sources.list
debian:~# echo 'deb-src http://www.pvv.ntnu.no/~knuta/xmms/squeeze ./' >> /etc/apt/sources.list
debian:~# apt-get update && apt-get -y install xmms

There are also deb xmms built for Ubuntu, so Ubuntu users could install xmms using repositories:

deb http://www.pvv.ntnu.no/~knuta/xmms/karmic ./
deb-src http://www.pvv.ntnu.no/~knuta/xmms/karmic ./
That’s all now xmms is ready to use. Enjoy :)

How to completely disable Replication in MySQL server 5.1.61 on Debian GNU / Linux

Monday, July 16th, 2012

Some time ago on one of the Database MySQL servers, I've configured replication as it was required to test somethings. Eventually it turned out replication will be not used (for some reason) it was too slow and not fitting our company needs hence we needed to disable it.

It seemed logical to me that, simply removing any replication related directives from my.cnf and a restart of the SQL server will be enough to turn replication off on the Debian Linux host. Therefore I proceeded removed all replication configs from /etc/my/my.cnf and issued MySQL restart i. e.:

sql-server:~# /etc/init.d/mysql restart
....

This however didn't turned off replication,as I thought and in phpmyadminweb frontend interface, replication was still appearing to be active in the replication tab.

Something was still making the SQL server still act as an Replication Slave Host, so after a bit of pondering and trying to remember, the exact steps I took to make the replication work on the host I remembered that actually I issued:

mysql> START SLAVE;

Onwards I run:

mysql> SHOW SLAVE STATUS;
....

and found in the database the server was still running in Slave Replication mode

Hence to turn off the db host run as a Slave, I had to issue in mysql cli:

mysql> STOP SLAVE;
Query OK, 0 rows affected, 1 warning (0.01 sec)
mysql> RESET SLAVE;
Query OK, 0 rows affected, 1 warning (0.01 sec)

Then after a reload of SQL server in memory, the host finally stopped working as a Slave Replication host, e.g.

sql-server:~# /etc/init.d/mysql restart
....

After the restart, to re-assure myself the SQL server is no more set to run as MySQL replication Slave host:

mysql> SHOW SLAVE STATUS;
Empty set (0.00 sec)

Cheers ;)

Fixing QMAIL mail server SMTP auto-configure issues in Thunderbird and other mail IMAP / POP3 mobile clients

Friday, July 13th, 2012

One of the QMAIL mail servers, setup-uped on a Debian host has been creating some auto configuration issues. Every-time a new mail user tries to use the embedded Thunderbird client auto configuration, the auto config fails leaving the client unable to use his Mailbox through POP3 or IMAP protocols.

Since about 2 years Thunderbird and many other modern pop3 and imap mail desktop and mobile clients are by default using the auto configuration and hence it was unthinkable to manually change settings for new clients with the QMAIl install; Besides that most of the Office users are always confused, whether they have to manually change SMTP or POP3 host for a server.

Below is a screenshot displaying the warning during email auto-configuration:

Thunderbird new Mail account setup auto config warning SMTP not OKThe orange color in the button for the newly auto-detected smtp.mail-domain.com indicates, something is not right with the SMTP host.

Obviously, something was wrong with smtp.mail-domain.com, hence I checked where smtp.mail.domain.com resolves with host command. What I found was actually smtp.mail-domain.com Active ( A ) DNS records was pointing to an IP address, our company previously used for the mail server. At present time the correct mail server host name is mx.mail-domain.com and the QMAIL installation on mx.soccerfame.com is configured to be the actual SMTP server.

By default Thunderbird and many other POP3, IMAP mail clients, however automatically assume the default SMTP host for a mail server is to be configured under a host name smtp.mail-domain.com. This is really strange, especially when the primary MX record for mail-domain.com domain is pointing to mx.mail-domain.com, e.g.:

qmail:~# host -t MX mail-domain.com
soccerfame.com mail is handled by 10 mx.mail-domain.com.
soccerfame.com mail is handled by 20 mail.mail-domain.com.
soccerfame.com mail is handled by 30 mail-domain.com.

The whole warning was caused due to the fact mx.mail-domain.com was resolving to an IP like xxx.xxx.xxx.xxx, whether smtp.mail-domain.com was resolving to yyy.yyy.yyy.yyy

Both xxx.xxx.xxx.xxx and yyy.yyy.yyy.yyy hosts were configured to have a different qmail SMTP host i.e.:

The server under IP xxx.xxx.xxx.xxx – (mx.mail-domain.com) was configured in /var/qmail/control/me to be mx.mail-domain.com and the other old one yyy.yyy.yyy.yyy – (mail.mail-domain.com) had (mail.mail-domain.com) in /var/qmail/control/me

As smtp.mail-domain.com was actually being still resolved to mail.mail-domain.com, the EMAILs were improperly trying to be sent with a configured DNS hostname of smtp.mail-domain.com, where the actual one on the server was mail.mail-domain

It took, me about an hour of pondering what is causing the oddities until I got the here explained issue. As the DNS recors for the domain the sample mail-domain.com were handled by Godaddy, to fix the mess, I logged in to Godaddy and;

a) deleted – DNS record for smtp.mail-domain.com.
b) Created new CNAME record for smtp.mail-domain.com to be a domain alias for mx.soccerfame.com

A few minutes, afterwards I tried configuring once again the same email account in Thunderbird and this time both imap.mail-domain.com and smtp.mail-domain.com turned green; indicating everything is configured fine.

To be 100% sure all is working fine I first fetched, all email via the IMAP protocol without hassles and onwards sent a test email to my Gmail account; thanksfully the sent email was delivered to Gmail indicating both Get Mail and Send Mail functions worked now fine.

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 ?

The lack of sharing in modern world – One more reason why sharing Movies and any data on the Internet should be always Legal

Saturday, July 7th, 2012

Importance of sharing in modern digital society, sharing should be legal, Sharing caring
 I've been thinking for a lot of time analyzing my already years ongoing passion for Free Software, trying to answer the question "What really made me be a keen user and follower of the ideology of the free software movement"?
I came to the conclusion it is the sharing part of free software that really made me a free software enthusiast. Let me explain ….

In our modern world sharing of personal goods (physical goods, love for fellows, money, resources etc.) has become critically low.The reason is probably the severely individualistic Western World modern culture model which seems to give good economic results.
Though western society might be successful in economic sense in man plan it is a big failure.
The high standard in social culture, the heavy social programming, high level of individualism and the collapsing spirituality in majority of people is probably the major key factors which influenced the modern society to turn into such a non-sharing culture that is almost ruling the whole world nations today.

If we go back a bit in time, one can easily see the idea and general philosophy of sharing is very ancient in nature. It was sharing that for years helped whole societies and culture grow and mature. Sharing is a fundamental part of Christian faith and many other religions as well and has been a people gathering point  for centuries.
However as modern man is more and more turning to the false fables of the materialistic origin of  man (Darwininsm), sharing is started seeing as unnecessary . Perhaps the decreased desire in people to share is also the reason why in large number people started being  self-interest oriented as most of us are nowadays.

As we share less and less of our physical and spiritual goods, our souls start being more and more empty day after day. Many people, especially in the western best developed societies; the masses attitude towards sharing is most evidently hostile.
Another factor which probably decreased our natural human desire to share is technocracy and changing of communication from physical as it used to be until few dacades to digital today.

The huge shift of communication from physical to digital, changes the whole essence of basic life, hence I believe at least the distorted sharing should be encouraged on the Internet (file movies and programs sharing) should be considered normal and not illegal..
I believe Using Free Software instead of non-free (proprietary) one is another thing through which we can stimulate sharing. If we as society appreciate our freedom at all  and  care for our children future, it is my firm conviction, we should do best to keep sharing as much as we can in both physical and digital sense.

How to configure VIVACOM 3g USB ( internet ) modem HUAWEI Mobile broadband E173 on Debian and Ubuntu GNU / Linux

Wednesday, July 4th, 2012

I've been given a HUAWEI Mobile Broadband E173 USB 3g model. The USB modem contains a flash USB Storage segment storing a little install program dedicated to make the modem work fine on Microsoft Windows XP / Vista / 7 and probably other M$ OSes. I'm a long time DebianGNU / Linux user and as a free software enthusiast I ofcourse wanted to be able to use Vivacom's 3G USB Modem on my Linux powered notebook.

Thanksfully as I've red on Vivacom's website the modem supports Linux OS :)

For those unaware in Bulgaria there are currently 3 major GSM network providers providing 3G internet this are;;;
 

  • VIVACOM – The ex Government ran national company BTC (Bulgarian Telecommunication Company)
  • M-Tel – The first GSM network provider that entered Bulgaria around year 1995
  • GLOBUL – The 3rd and last GSM mobile and net provider entered last and not so much used by Bulgarians today

Until today I had no experience in running any 3G modems on Linux, neither I had used the 3 networks 3G internet to determine which one is best, however I've been given for temporal use a VIVACOM 3G internet modem today so I proceeded to try installing it on my Debian host.

My Linux system is a bit strangely configured as I use wicd network connection manager -( wicd-gtk ) to manage wireless and LAN connections instead of the standard installed GNOME network manager – available through package ( network-manager-gnome ).

The reason I use wicd is not that it is so much better than GNOME network manger but rather for historical reasons because few years past I had impression it works better in connecting me to wireless networks. Another reason why I choosed wicd back then was the nice looking stats …

I tried plugging in the Vivacom USB 3G modem stick and checked in wicd to see if I can see a possibility to connect to the mobile opeartor 3G network but unfortunately nothing appeared.

Though the 3G adsl modem was unavailable straing in wicd, checking about it in the list of attached USB devices I could see it detected, e.g.:

noah:~# lsusb |grep -i huawei
Bus 001 Device 007: ID 12d1:1c05 Huawei Technologies Co., Ltd.

This was at least a good sign pointing me to the thoughts that the modem is probably gonna work.

I did a quick Google search to see if other people succeded running the device on a Linux host and came across a few blog posts in Bulgarian explaining a "success story" on Ubuntu Linux through using a tweakened shell script – sakis3g. For more on how the script works and script download check out Sakis3g

Here is a quote from sakis3g's website describing the script:
 

It automagically setups your USB or Bluetooth™ modem, and may even detect operator settings.
You should try it when anything else fails!

Sakis3g has different versions designed for for plenty of spacific hware architectures i.e. for (i386, amd64, armv4t, armv5t).
There is also a version of the script which by the way contains a combination of bash shell scripting instruction and some binary exec data.

To run sakis3g on my laptop I did:

1. Download sakis3g

My notebook architecture is 64 bit so I download and used the amd64 version of the script;;;

hipo@noah:~$ mkdir sakis3g
hipo@noah:~$ cd sakis3g
hipo@noah:~/sakis3g$ wget http://www.sakis3g.org/versions/latest/amd64/sakis3g.gz

I've made also a mirror of sakis3g i386, 64 bit and all architecture the mirrors just in case it disappears in future. The mirror versions of sakis3g are here:

a. sakis3g i386 b. sakis3g amd64 c. sakis3g all architectures source

2. Unarchive and make it executable

After downloading it as it is in gzip I had to do the usual de-gzipping and making the file executable;;;

hipo@noah:~/sakis3g$ /bin/gzip -d sakis3g.gz
hipo@noah:~/sakis3g$ chmod +x sakis3g

The script is then ready to run by either clicking twice on it or (as I prefer for debugging reasons to run it in terminal):

hipo@noah:~$ ./sakis3g

Something that I have wondered a bit was the dialog where I had to fill in some data of some variable APN abbreviation for – (Access Point Name)

The APN host for VIVACOM mobile internet is;;;
APN: internet.vivacom.bg

I've used the Windows configuration progrma to gather also the following data that I thought might be important for configuring the 3G adsl modem on the Linux host;;;

Auth: *99#
User: VIVACOM
pass: VIVACOM

Here are all the configuration screenshots I've taken from sakis3g and all the data that I filled in.
Next the following tiny window appeared on screen:

Well that's all folks, now sakis3g succesfully connected to the I_net via an (PPP) VPN connection tunnel here is data from ifconfig command showing the succesful 3G connection to VIVACOM;;;

The internet via the 3G connection is not blazing fast but good enough to check your mail or read some webpages. VIVACOM currently has different (traffic limited packages) for their 3G internet, I'm not sure which package exactly is the 3G USB stick modem but probably the "quick" internet connection that is now would slow down once the traffic limit is reached …
Hope this post helps someone to configure 3G internet on VIVACOM in Debian and Ubuntu Linux. Though I've tested sakis3g on Debian it should work with no hassles on any other GNU Linux distribution that has bash installed.
