I've seen people online blaming Stallman and Free Software Movement for being communistic. I've thought over it for a while so decided to give my 5 cents rant on that. Obviously there is still people in America who doesn't make difference between capitalism, communism and socialism. Yes it is true, GNU / Linux and Free Software are socialistic in essence and obviously Stallman's ideas are close to Socialists ideas, but for sure in his essence its not against capitalism and even less against democracy. So why there are still people recognizing free software as communistic? I think it is due to their mis-understanding that Free Software doesn't stand for making people equal but it is for giving chance to everyone who has interest to learn and doesn't have the financial possibility to do it. By its existince free software gives the poor Afrika's population legal way to install and use software free of charge. The idea of free software is purely scientific, there are plenty of researchers who denied patenting their invention because they wanted to share their findings with the world like Willhelm Roentgen's finding of X-rays. FS is for giving to society it is for software for people who should not be necessary divided by social status or bank account. Free Software puts out bariers since its fosters a spirit of community so much lost in our very divided century, it makes people involved in FS opened to itself and being friends no matter of social status. It is to make people free to choose and do whatever they like with each software it is about transperancy and equal start to programmers and computer enthusiasts. I'll be curious to hear people's opinion?

Happy Birthday GNU – Celebrating 30 years of Free Software and Computer Freedom!
Friday, September 27th, 2013On 27 of September this year (2013) Richard Stallman's GNU Project celebrates its 30 years Anniversary! Richard started the GNU Project and devoted his last 30 years of his life and thanks to him now we have free software. His work is remarkable. Million of GNU / Linux System Administrators and Programmers (including me in this number) round the world today has a daily income thanks to RMS. Interestingly the GNU Project was started in year I was born in the distant 1983. In fact the GNU Project is older than me with a couple of days (I'm born on 8-th of October 1983! :). Probably it is not a coincidence that I got so interested in Free Software GNU and Software freedom as the project was started so near my birthdate 🙂
Here is how RMS Announced the existence of GNU project and the general philosophy behind it:
I consider that the golden rule requires that if I like a program I must share it with other people who like it. I cannot in good conscience sign a nondisclosure agreement or a software license agreement.
So that I can continue to use computers without violating my principles, I have decided to put together a sufficient body of free software so that I will be able to get along without any software that is not free.
You can read whole original Stallman announcement here
Stallman's GNU Project is a good example how a single man who believes in something can change the world, by sticking to his believes. We all know Stallman is a true hacker legend, besides that as a friend used to say RMS is one of the greatest philosophers of our times. Stallman doesn't have kids but according to his words for him the GNU Project is like his Child. His Virtual Child gave chance to millions of people around the world to study source codes and develop in their career. Even his child gave birth to thousands of hundred other "hacker" childs 🙂
Again, Happy Birthday GNU!!!
I wish Stallman another 30 years of work in field of protection of Human Liberty and Software Rights!

SumatraPDF Adobe Acrobat Reader free software ( Secure ) Alternative
Friday, July 19th, 2013Whether you're forced to use MS Windows but still want to use as much as possible Free Software – i.e. Stay away from Non-Free Adobe Acrobat Reader. There is Sumatra PDF – a good alternative that reads well most of PDFs. For rendering PDF Sumatra PDF usees muPDF library. SumatraPDF is minimalistic software it does exactly what it is meant for – reads PDF. Unfortunately from version 0.6 of Sumatra there is DRM implemented (Digital Right Managements) so it is not possible to copy from DRM-ed documents.
Sumatra opens following formats: Open XML Paper Specification, DjVu, EPUB, XPS, CHM, CBZ and CBR, and MOBI files.
As of time of writting official Sumatra PDF version is at ver. 2.3.2
I've made mirror of Sumatra PDF 2.3.2 installer here , Sumatra PDF zipped is here
Sumatra PDF works on Windows XP, Vista, Win 7 & 7
One of key advantages of Sumatra PDF over Adobe Acrobat Reader is you don't need to update it all the time and it is much less likely that Sumatra PDF is hit by security flaw in PDF format.
For people who use Linux / BSD or some other Unix and want to stay free from proprietary Adobe Acrobat Reader two nice alternatives are default's GNOME PDF reader Evince and KDE's Okular

PeaZip good Windows and Linux free software alternative to non-free WinRar and WinZip archiver tools
Thursday, June 27th, 2013 Until recently it was almost impossible to have Microsoft Windows without WinRar and WinZip archiver programs installed.
Though both can be used as trial versions for personal use for commercial use one had to purchase license. It is pretty annoying that each time you run Winrar you get reminded you're using its trial version. As I'm trying to substitute all non-free software with free software even whether I have to install or maintain Windows, just recently I found out about existence of PeaZip – Free Zip file utility / Free Rar Extractor.
Besides being open source software PeaZip and supports Windows it is also available prepackaged for Linux / BSD as well.
PeaZip supports unarchiving of 150 archive file types, and by installing it you save time otherwise spend in installing two separate tools on Windows. It can do plenty of other useful stuff for instance joining / splitting files ending in suffix (001, 002, 003) etc. as well as splitting archives in parts (…part1, …part2, …part3 …), create self-extracting (.exe) archives, do multiple archives at once.
Here is list of most popular archive file types supported to browse / test / archive / dearchive:
7z, bz, bz2, bzip2, tbz2, tbz, gz, gzip, tgz, tpz, tar, zip, zipx, z01, smzip, arj, cab, chm, chi, chq, chw, hxs, hxi, hxr, hxq, hxw, lit, cpio, deb, lzh, lha, rar, r01, 00, rpm, z, taz, tz, iso, jar, ear, war, lha, pet, pup, pak, pk3, pk4, slp, [Content], xpi, wim, u3p, lzma86, lzma, udf, xar, dmg, hfs, part1, split, swm, tpz, kmz, xz, txz, vhd, mslz, apm, mbr, fat, ntfs, exe, dll, sys, msi, msp, ods, ots, odm, oth, oxt, odb, odf, odg, otg, odp, otp, odt, ott, gnm, doc, dot, xls, xlt, ppt, pps, pot, docx, dotx, xlsx, xltx, swf, flv, quad, balz, zpaq, paq8f, paq8jd, paq8l, paq8o, lpaq1, lpaq5, lpaq8, ace, arc, wrc, 001, pea, cbz, cbr, cba, cb7, cbt …
Even better PeaZip has ports for both 32 and 64 bit Windows (XP / Vista / 7 and 8), Linux and *BSD. Official PeaZip download page is on Sourceforge here
Next time you need multi-format unarchive program on a new Windows install, give it a try.
PeaZip has good compitability with new versions of WinRar and WinZip archived files, so it is not very likely you will ever in future need these proprietary applications.
One note to make is during install as most software, it offers installing some useless stuff like "Free Smilies" and a Toolbar, make sure you don't click Next by mistake – ( un-tick them ) !
For Linux users on PeaZip's website there is package in deb, rpm and tgz. Packages are available with builds for GNOME graphical environment with GTK2 lib or KDE QT.
I tried installing PeaZip on my Debian 7 Wheezy downloading deb provided by Sourceforge, but install failed with error:
noah:~# dpkg -i peazip_5.0.LINUX.GTK2-2_all.deb
Selecting previously unselected package peazip.
(Reading database … 226682 files and directories currently installed.)
Unpacking peazip (from peazip_5.0.LINUX.GTK2-2_all.deb) …
dpkg: dependency problems prevent configuration of peazip:
peazip depends on libgmp3c2; however:
Package libgmp3c2 is not installed.
dpkg: error processing peazip (–install):
dependency problems – leaving unconfigured
Errors were encountered while processing:
peazip
In previous Debian release Squeeze there was package libgmp3c2 but it is no longer available from repos on Wheezy. Thus to install it on Wheezy I used Universal Linux .TGZ Package and just extracted it in root directory ( / ):
noah:~# cd /
noah:/# links http://sourceforge.net/projects/peazip/files/5.0/peazip-5.0.LINUX.GTK2.tgz/download
noah:~# tar -zxf peazip-5.0.LINUX.GTK2.tgz
To run it:
hipo@noah~:$ /usr/local/bin/peazip
PeaZip's archive / unarchive operation speed compared to CPU use and memory consumption is fast, though it eats a bit more ram than GNOME's default Archive Tool – File Roller.
Thanks God for PeaZip! Buy-buy forver to Winrar and Winzip 🙂

How to change MySQL server root password
Friday, July 29th, 2011I had to change my mysql root password for one of the servers since during the install I mispasted the password in the MySQL password prompt I needed the pwd to be changed.
Here is how I changed it to my desired one:
linux:~# /usr/bin/mysqladmin -u root -p'OLD_PASSWORD_STRING' password NEW_PASSWORD_STRING
linux:~#
The password gets changed immediately 😉
If a new password has to be set to a passwordless mysql server, the command to be issued is:
linux:~# /usr/bin/mysqladmin -u root password PASSWORD_STRING
Changing the MySQL password is also possible with mysql cli, after connecting to the sql server, though this method is a bit more time consuming. Here is how to do it from mysql console:
linux:~# mysql -u root -p
Server version: 5.1.49-3 (Debian)

Type ‘help;’ or ‘h’ for help. Type ‘c’ to clear the current input statement.
mysql> use mysql;
mysql> update user set password=PASSWORD(“NEW_PASSWORD”) where User=’root’;mysql> flush privileges;
Of course it’s possible to do change the root pass via phpmyadmin
Cheers 😉

How to delete MySQL user using mysql cli command
Monday, September 24th, 2012I decided to clean up a bit my MySQL obsolete users. I use to test free software every now and then and often in the hurry I forgot to clean up the respective soft database and created user in database/table mysql.user.
This is how this tiny article get born. Deleting users in version MySQL 5.0 and higher use command:
mysql> DROP USER username@localhost;
On older MySQL versions; 3.x / 4.x the SQL query is a bit longer:
mysql> DELETE FROM user WHERE User= 'type_your_user_name_here' AND Host= 'localhost'; mysql> FLUSH PRIVILEGES;
Well that's all, now user is wiped out, Enjoy 🙂

Create ASCII Art Text banners in GNU / Linux console and terminal with figlet and toilet
Tuesday, January 15th, 2013 As an old school hobbyist, I'm a kind of ASCII art freak. Free Software is just great for this text / console maniacs like me, who spend their youth years in a DOS (Disk Opearting System) command prompt.
For long time, I'm researching the cool programs which has to do somehow with ASCII Art, in that relation I decided to write few ones of figlet and toilet – two nice programs capable of generating ASCII art text beautiful banners based on a typed in text string. Obviously toilet developer Sam Hocevar had a great sense of humor 🙂
To play with figlet and toilet install them, according to (rpm or deb based package manager on distro) with yum / apt-get.
yum -y install toilet figlet
....
apt-get --yes install toilet figlet
....
There are no native tool packages for Slackware, so Slackaware Linux users need to compile figlet from source code – available on figlet's home page figlet.org
Once figlet and toilet are installed, here is few sample use cases;
hipo@noah:~/Desktop$ figlet hello world!
hipo@noah:~/Desktop$ figlet -f script Merrcy Christmas
Plenty of figlet font examples are available on Figlet's website example section – very cool stuff btw 🙂 To take a quick look on all fonts available for toilet – ascii art banner creation. Type in your console tty or terminal;
for i in $(dpkg -L toilet-fonts|grep -i /usr/share/figlet); do toilet -f $(echo $i|sed -e "s#.tlf##g" -e "s#/usr/share/figlet/##g") test; done
On below picture, I made a screenshot of my gnome terminal with most fonts installed by toilet-fonts (fonts package).
There are about 150 fonts, most of which needs to be downloaded and installed manually. A quick search online led me to a fonts collection of 263 figlet ascii art fonts – you can download a mirror of the file figletfonts40.zip here. To aid up toilet and with those 263 extra fonts (on Debian) do;
wget https://www.pc-freak.net/files/figletfonts40.zip cd /usr/share/figlets unzip figletfonts40.zip
Note: you have to have installed unzip in advance, unzip is not in default install, so if you don't have it fetch it with;
apt-get install --yes unzip
toilet and figlet are partially compatible, between each other so most fonts should work okay on both.
figlet supports, also simple formatting of ASCII art banner, here is few examples with formatting; a.) format to center
$ figlet -c bla bla
b.) format to left
c. right formatting
d. format to terminal width By default text that figlet generates is to suit for 80 rows terminals, normally on higher resolution in gnome-terminal and other Linux environments, terminals are not dimensioned 80×25, thus it is useful for longer sentences text to display text in accordance to terminal size;
The cool thing and advantage of toilet over figlet is toilet can print out ASCII art banners in colors – very very cool stuff; To quickly test all filters issue;
for i in $(toilet -F list|awk '{ print $1 }'|grep -v Available|sed -e 's#"##g'); do toilet -F $i pC-fREAK; done
Change text pC-fREAK with whatever you like;
>
Very nice use of toilet or figlet, can be if it is placed to produce some nice message in ASCII banner on each user login. Other nice fun applications is together with cowsay.
apt-cache show cowsay|grep -i description -A 5 Description: A configurable talking cow Cowsay (or cowthink) will turn text into happy ASCII cows, with speech (or thought) balloons. If you don't like cows, ASCII art is available to replace it with some other creatures (Tux, the BSD daemon, dragons, and a plethora of animals, from a turkey to an elephant in a snake).
In case interested in using cowsay on system logins, I suggest you check out my tiny cowrand script which uses cowsay and shows random cow ASCII art picture on each user login.
Also a good use if you're Christian is to combine, some nice Holy Scriptures verse in text ascii with some encouraging daily bible phrase from verse or fortune.
Apart from fun, common use of ASCII art slogans is in e-mail or blog comments ASCII art signatures, also they are certainly good for creating unusual (text) advertisements and even can be used to save printer ink:) cause text generated in ASCII art logo is not massive like most text fonts are 🙂 Last but not least ASCII art banners are useful in generation of ASCII slogans as an art; after all ASCII art is one of innovative arts of 21st century 🙂

How to convert Adobe PDF file format to Microsoft Word DOC on MS Windows 2000 / XP / Vista / 7
Tuesday, July 24th, 2012
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.

Enabling talkd (Console Chat) between logged in users on FreeBSD and other BSDs
Sunday, June 10th, 2012Those who are in familiar with older UNIXes, UNIX BSD derivatives and GNU Linux should certainly remember the times, when we hackers used to talk to each other using talk service.
Those who don't know what talk command is it is a simple console / ssh utility to talk to another logged in users.
Talk is very similar to write and mesg one liner messasing utilities available for *nixes, the difference is it is intendted to provide interactive chat between the two logged in users. People who came to know UNIX or free software in older times most likely don't know talk, however I still remember how precious this tool was for communication back in the day.
I believe still it can be useful so I dediced to install ot on one FreeBSD host.
In order to have the talk service running on BSD it is necessery to have /usr/libexec/ntalkd installed on the system this however is installed by default with standard BSD OS installs, so no need for any external ports install to run it.
talk doesn't have it's own init script to start is not written to run as it own service but in order to run it is is necessery to enable it via inetd
Enabling it is done by;;;
1 — Editting /etc/inetd.conf
Inside the conf the line::
#ntalk dgram udp wait tty:tty /usr/libexec/ntalkd ntalkd
should be uncommented e.g, become ;;;
ntalk dgram udp wait tty:tty /usr/libexec/ntalkd ntalkd
2 — Restart inetd
freebsd# /etc/rc.d/inetd restart
Stopping inetd.
Starting inetd.
talk is planned to be used for peer to peer conversations over SSH so in a way it is the GRANDFATHER 🙂 of IRC, ICQ and Skype;;;
Here is an example on how talk is used ,, Let's say there are three logged in users
pcfreak# w
12:39PM up 3 days, 16:25, 3 users, load averages: 1.12, 0.91, 0.71
USER TTY FROM LOGIN@ IDLE WHAT
testuser p0 192.168.0.7 10:50AM - bash
hipo p3 192.168.0.8 12:23PM - w
root p4 :ttyp2:S.0 12:24PM - vim /usr/local/www/dat
I'm logged in with my username hipo and I would like to talk to testuser ;;;;
pcfreak% tty
/dev/ttyp3
You see I'm logged in on /dev/ttyp3 (this is the specific naming on BSDs) on Linux equivalent is /dev/tty3So to talk the other user testuser;;;;;-
$ talk testuser ttyp0
[No connection yet]
[Waiting for your party to respond]
The testuser logged in via SSH will then get a message ||;
Message from Talk_Daemon@pcfreak at 12:44 on 2012/06/10 ...
talk: connection requested by hipo@localhost
talk: respond with: talk hipo@localhost
To enter a talk session then the logged in testuser has to type:
$ talk hipo@localhost

How to check the IP address of Skype (user / Contacts) on GNU / Linux with netstat and whois
Thursday, May 3rd, 2012 Before I explain how netstat and whois commands can be used to check information about a remote skype user – e.g. (skype msg is send or receved) in Skype. I will say in a a few words ( abstract level ), how skype P2P protocol is designed.
Many hard core hackers, certainly know how skype operates, so if this is the case just skip the boring few lines of explanation on how skype proto works.
In short skype transfers its message data as most people know in Peer-to-Peer "mode" (P2P) – p2p is unique with this that it doesn't require a a server to transfer data from one peer to another. Most classical use of p2p networks in the free software realm are the bittorrents.
Skype way of connecting to peer client to other peer client is done via a so called "transport points". To make a P-to-P connection skype wents through a number of middle point destinations. This transport points (peers) are actually other users logged in Skype and the data between point A and point B is transferred via this other logged users in encrypted form. If a skype messages has to be transferred from Peer A (point A) to Peer B (Point B) or (the other way around), the data flows in a way similar to:
A -> D -> F -> B
or
B -> F -> D -> A
(where D and F are simply other people running skype on their PCs).
The communication from a person A to person B chat in Skype hence, always passes by at least few other IP addresses which are owned by some skype users who happen to be located in the middle geographically between the real geographic location of A (the skype peer sender) and B (The skype peer receiver)..
The exact way skypes communicate is way more complex, this basics however should be enough to grasp the basic skype proto concept for most ppl …
In order to find the IP address to a certain skype contact – one needs to check all ESTABLISHED connections of type skype protocol with netsat within the kernel network stack (connection) queue.
netstat displays few IPs, when skype proto established connections are grepped:
noah:~# netstat -tupan|grep -i skype | grep -i established| grep -v '0.0.0.0'
tcp 0 0 192.168.2.134:59677 212.72.192.8:58401 ESTABLISHED 3606/skype
tcp 0 0 192.168.2.134:49096 213.199.179.161:40029 ESTABLISHED 3606/skype
tcp 0 0 192.168.2.134:57896 87.120.255.10:57063 ESTABLISHED 3606/skype
Now, as few IPs are displayed, one needs to find out which exactly from the list of the ESTABLISHED IPs is the the Skype Contact from whom are received or to whom are sent the messages in question.
The blue colored IP address:port is the local IP address of my host running the Skype client. The red one is the IP address of the remote skype host (Skype Name) to which messages are transferred (in the the exact time the netstat command was ran.
The easiest way to find exactly which, from all the listed IP is the IP address of the remote person is to send multiple messages in a low time interval (let's say 10 secs / 10 messages to the remote Skype contact).
It is a hard task to write 10 msgs for 10 seconds and run 10 times a netstat in separate terminal (simultaneously). Therefore it is a good practice instead of trying your reflex, to run a tiny loop to delay 1 sec its execution and run the prior netstat cmd.
To do so open a new terminal window and type:
noah:~# for i in $(seq 1 10); do \
sleep 1; echo '-------'; \
netstat -tupan|grep -i skype | grep -i established| grep -v '0.0.0.0'; \
done
-------
tcp 0 0 192.168.2.134:55119 87.126.71.94:26309 ESTABLISHED 3606/skype
-------
tcp 0 0 192.168.2.134:49096 213.199.179.161:40029 ESTABLISHED 3606/skype
tcp 0 0 192.168.2.134:55119 87.126.71.94:26309 ESTABLISHED 3606/skype
-------
tcp 0 0 192.168.2.134:49096 213.199.179.161:40029 ESTABLISHED 3606/skype
tcp 0 0 192.168.2.134:55119 87.126.71.94:26309 ESTABLISHED 3606/skype
...
You see on the first netstat (sequence) exec, there is only 1 IP address to which a skype connection is established, once I sent some new messages to my remote skype friend, another IP immediatelly appeared. This other IP is actually the IP of the person to whom, I'm sending the "probe" skype messages.
Hence, its most likely the skype chat at hand is with a person who has an IP address of the newly appeared 213.199.179.161
Later to get exact information on who owns 213.199.179.161 and administrative contact info as well as address of the ISP or person owning the IP, do a RIPE whois
noah:~# whois 213.199.179.161
% This is the RIPE Database query service.

source: RIPE # Filteredperson: Lyubomir Georgiev
.....
Note that this method of finding out the remote Skype Name IP to whom a skype chat is running is not always precise.
If for instance you tend to chat to many people simultaneously in skype, finding the exact IPs of each of the multiple Skype contacts will be a very hard not to say impossible task.
Often also by using netstat to capture a Skype Name you're in chat with, there might be plenty of "false positive" IPs..
For instance, Skype might show a remote Skype contact IP correct but still this might not be the IP from which the remote skype user is chatting, as the remote skype side might not have a unique assigned internet IP address but might use his NET connection over a NAT or DMZ.
The remote skype user might be hard or impossible to track also if skype client is run over skype tor proxy for the sake of anonymity
Though it can't be taken as granted that the IP address obtained would be 100% correct with the netstat + whois method, in most cases it is enough to give (at least approximate) info on a Country and City origin of the person you're skyping with.
