You are a reflection of the truth seen by your eyes, analyzed by your brain, performed by your mouth and given you by hand. The truth which is absolute on your natural instinct is the base for pragmatism and the ability to learn, accept and grow, never forget to reason – why, and choose the destiny forever.

Hi all, I’ve created a new composition called Fantasy in a dream – this composition is special, due to the fact that it is played live without thought. Art without art, music as I hear and see it in my dreams, it is strong, explosive and very deep few layers down. Enjoy this dream…

First of all, iSCSI protocol cannot run in NATed environment, due to protocol implementation which makes the LUN scan over different TCP session, and ports which are used there are not trivial… So will work only in LAN, or WAN.

iSCSI target for Linux – sources for compiling.

iSCSI initiator exists on following linux OS installations, windows is not supported:

RHEL – 5.6/7 6.0 and 6.1
iSCSI consists of server and client sides. iSCSI target is installed on the server side and iSCSI initiator is used on the client.

iSCSI target installation process:

tar xvfz iscsitarget-1.4.20.2.tar.gz
cd iscsitarget-1.4.20.2
make && make install
iSCSI target configuration process:

vi /etc/iet/ietd.conf (Add the following line – we are going to use images created by using the dd utility, see the example for creating the image files below (delete everything else there)
Target iqn.2001-04.com.example:storage.lun1
IncomingUser iscsi Password1
OutgoingUser iscsi Password1
Lun 0 Path=/media/sdb1/storage/lun1.img,Type=fileio
Alias iscsi0
:wq
cd /media/sdb1/storage/
dd if=/dev/zero of=lun1.img bs=1024k count=10000 (the following line would create an image of 10GB size)
note the above configuration of /etc/iet/ietd.conf should point to correct path of the image file
restart the “/etc/init.d/iscsi-target restart” to load the new configuration
iSCSI initiator configuration process: (note the IP address is the IP address of the iSCSI target server, the following commands are automatically added to the iSCSI initiator configuration:
iscsiadm -m discovery -t st -p 10.76.5.125
iscsiadm -m node
iscsiadm -m node –targetname “iqn.2001-04.com.example:storage.lun1″ –portal “10.76.5.125:3260″ –op=update –name node.session.auth.authmethod –value=CHAP
iscsiadm -m node –targetname “iqn.2001-04.com.example:storage.lun1″ –portal “10.76.5.125:3260″ –op=update –name node.session.auth.username –value=iscsi
iscsiadm -m node –targetname “iqn.2001-04.com.example:storage.lun1″ –portal “10.76.5.125:3260″ –op=update –name node.session.auth.password –value=Password1
iscsiadm -m node –targetname “iqn.2001-04.com.example:storage.lun1″ –portal “10.76.5.125:3260″ –login
vi /etc/iscsi/iscsid.conf and verify the following line exist: node.startup = automatic
Verify with fdisk -l that the new device name is added correctly
Now you can process to formatting and partitioning

אתה יכול לכתוב ספר – מאת: דניאל סלבודר 16/8/2012 dslabodar@gmail.com
- אתה יכול לכתוב ספר, אתה יודע?! אמרתי לו במלוא הביטחון
- אני יכול הכול, אם אני רוצה – אני יודע. הוא אמר זאת בפשטות, כאילו לא היה לו במה להתבייש.
הריח של הסיגריות מילא את החדר המדרגות, הרעש וההמולה מסביב, אי אפשר היה להבין מי מדבר על מה. במידת האפשר, מצאתי את עצמי עומד מעל האיש לא בגובה העניים, אלא על המדרגות, כראש מעל, הרגשתי לא נוח עם זה.
- אני לא שופט אותך, אתה חופשי לעשות כל מה שאתה רוצה ויודע מה שאתה רוצה. אני רק אומר שאתה יכול לכתוב ספר.
מה המודל המצליח לכתיבת ספר, האם ספר צריך להיות מצליח או סתם ספר על כלום, סתם כדי להעביר את הזמן. מאיפה רמת הביטחון השקרית שלי להמליץ למישהו לעשות משהו? האם אני מומחה לחיפוש כישרונות לשירה או למוסיקה? מאיפה זה בא? הרגשתי נבוך, אמרתי שטות, הבנתי את זה מיד לאחר מכן. האיש התחיל לספר על השעון שלו, מעין הסבר והתנצלות על סטטוס שלו, למה הוא בכלל נמצא פה בחדר המדרגות מלא עשן, במפגש קודם היה כולו רדום תחת השפעה כבדה. היום הוא נינוח, בטוח בעצמו וידע הכול. הדיבור הקצר והלקוני הזכיר לי מישהו מוכר, הוא היה איש מחשבים מוכשר, היה תמיד מדבר קצר ולעניין, חיבבתי אותו איכשהו, והאיש שיכול לכתוב ספר הזכיר לי אותו. איך התחברתי לאיש עם השעון?
- השעון שלי עולה 2000 דולר.
התחילה פולמיקה ארוכה, איך הוא קנה ומכר ולאחר מכן שוב קנה בזול ואני איבדתי אותו, ברגע שאמר את המשפט השעון שלי עולה… פולמיקה לאיש הלקוני בעולם!
- אני לא שופט אתך, השעון שלי עולה 2000 שקל.
האמת לא, השעון שלי עלה 1500 לפני 15 שנה, המספר 15… שוב שקר. שקר? והחזרה למשפט מגן, אני לא שופט אותך? למה אני מתנצל?
הריח הזה, לקחתי סיגריה, עישנתי אותה מהר, הרגשתי את הטעם של הניקוטין בשפתיים והחום, נהיה לי מגעיל. הגיע זמן ללכת…
חזרה לכיתה. בשיעור מלמדים אותך להיות איש יצירתי, חכם, נבון, נינוח ועד סיסמאות וקלישאות. אני הולך לשיעורים הללו למצוא את עצמי תובע בסיסמאות, קשה מאוד למצוא את האמת שלי. זה כנראה לוקח עוד זמן, כל עוד יש מישהו שכותב את הספר – אני רגיל לקבל את כל התשובות מהר. הרי כל כך קל ליפול בתוך השקר היצירתי שאתה בונה לעצמך – העולם שאותו אתה כל כך אוהב, הגיע הזמן לעזוב, אין תשובות מהירות.
הרחוב כבר חשוך, החנויות מוכרות סיגריות מסטיקים שתייה מתוקה עם גזים, נוסעות מכוניות – חם. אני הולך מהר גם אם כי חם לי, אבל אני בורח מעצמי, מהאיש הלקוני שיכול לכתוב ספר. יש עוד שעה עד שהרכבת תיקח אותי הביתה – לא הביתה, לתחנת רכבת ולאחר מכן אוטובוס למושב. עוד 20 דקות הליכה ואני בבית. זה לוקח שעתיים, כך זה כל שבוע, כך, זו הדרך, תמיד לומדים.
לפני השינה, אני מרגיש את הבטן שלי, היא מתהפכת, כמה תרגילי נשימה שלמדתי אצל הפסיכולוגית והחרדה תעבור ואני אירדם עד ליום חדש. שהעניים נסגרות הספר נפתח מול עיניים עצומות ואני מתחיל לקרוא.
אתה יכול לכתוב ספר, אמרתי לאיש מלא בביטחון.

Unfortunately, I had to block access to /music :( People started to share links and various music sites checking the availability of my music online started to play it automatically without even knowing it… So currently I have user and password there, just to stop these idiots. If you need password and username just message me or send me an email.

A good friend of mine left to Canada… I hope he and his family would do well there. Another friend is getting divorced… A job I do, is interesting, I enjoy it, sometimes it is hard, but if I plan and stick to the plan, everything works just fine. Started to do more sports twice or even three times per week, I progress in weight lifting, started to gain my weight too. Eating and feeling almost normally, less heartburns, although, I think it is also related to the fact that I went to some nutritionist to take some natural food addons, which helped.

Met with friends for lunch at goocha today, was really nice and fish was very spicey :) Alex prepared a photoalbum of his photographs and it is really admirable that he made a complete work of his photos! Congrats Alex! here his site to visit: http://www.hectic.net

Other things to mention, the Reiki album was a disaster… No one talked about it, wether it was good or bad or anything. And it made me really sad, I started to think maybe I’m doing somethig wrong? Or my music started to bore… I stopped and looked on myself, and found that my music is boring. It made me feel really bad. And currently I stopped creating, I think of how do I really compose something that is interesting and smart, as I did few years ago. Then people really loved my music, which currently not the situation.

Thoughts about the issue with my music are currently none, except the fact that I always based on harmony as basis and generated improvisational melodies around the harmony structure. I found that my harmony knowledge is fulfilled, and not interesting anymore, I need to find other ways to compose.

Our life seems to be very fast during the past decades, we live to succeed and achieve until the age of 40, get as many deseases as possible, get as many stress as possible and eventually die from suffering… Why? Do we really have to choose to live and then die that way? The answer is in our hands.

What is EFT? Founded by Gary Craig, is a technique to perform two basic things - control your mind and help your body doing it. Actually what it does in real life is very silly, as one might catch another human doing it. The person stands in the middle of the street performing some strange ritual tappings on his eyes, fingers – saying to himself some strange sentences, humming some cheerful melody, performing that nicely, seems to other that he cannot be distracted at all. Then like nothing happened he continues to walk. How strange, the other guy thinks, what the hell was that? That is EFT.

What is beautiful about this technique that it combines three very deep and sophisticated approaches to heal the human being: Fix the feeling and automatic thought that you have which in Psychiatry called (CBT cognitive behavioral therapy), free your mind programming it to a new sentence with help of saying something to yourself lots of times, tap with fingers according to Chinese medicine accupuncture technique to specific points in your body. All this within 3-5 minutes of practice and you’re done. Some would say, this is total bullshit! Accupuntcure exists 2000 years and not many knows how and where to put a niddle, but tapping? Saying sentences to yourself? Fixing automatic thoughts? Well, it’s not a bullshit after all, I’ve tried it and it works. I read many books about CBT including the famous book by Albert Ellis (control your anxiety before it controls you), I know how CBT works, and it works fine, but you have to have lots of patience to succeed, what EFT does is helping you concentrate on CBT and therefore fixing two things in one method. It practically works very good.

Well, apparently, some “script-kiddies” succeeded implanting a rootkit on my webserver, which is awesome :) I noticed it, accidentally performing a regular cleaning of my website for some unrequired files… Anyway, found few tar files inside /. With netstat -atunp I saw a strange connection performed automatically to few IRC servers with port 6667 and 7000, after I run few tcpdump and tcpflow sessions, I saw that it is a bot running on my server, cool! A Linux bot! Nice to meet you Linux bot! It took me an hour to find it and remove it, the most interesting shit, the bot used a backdoor located on Linux PAM patches or updates then it replaced bash env + lsof command so lsof command output displayed an illusion… That’s why it took me so long to locate and disable this shit. I started to look some further, found a user named user inside my passwd file, the shadow file had two root entries and exactly the same entry for user user… Apparantly, as I changed the root password it was automatically applied to user too :) Very nice piece of software guys! Anyway, you should try harder.

Вот. Почему? Как не странно, у меня вдруг появилось много работы, и я стал очень занят, просто не было времени писать. Зато, я меньше чем за месяц осилил 4 книги Лукьяненко про ночные, дневные, сумеречные и последние дозоры. Что вам сказать на эту тему, да, это не Дэн Браун, хотя стили где-то похожи, но все равно, в фантастике надо как то по интерестней что-ли… Не хватает развития темы, много урезок, персонажи не достаточно развиты… Все развивается вокруг мета тематики… Я конечно нов в этом стиле киберпанка, но все таки хотелось бы больше. Скажем так, Стругацких и Азимова я читал с упоем книга за книгой и может еще раз почитаю, а вот Сергея Лукьяненко, читать вновь не стану. Это все равно как покушать в Мак Дональдсе и запить Кока Колой. Я не скажу, что все книги Лукьяненко такие, но то что я прочитал тянутся в Мак Дональдс (Лабиринт Отражении, Спектр, Дозоры, Черновик, Чистовик) Спектр был бест, но не хватает той маленькой искорки стиля которой нельзя перепутать ни скем. Да… Жалко, но вот почему он это так делает я не знаю, таланта на писанину предостаточно, а вот стиллистики не хватает. Стал читать Владимира Панова по совету друга, серию Тайный Город, посмотрим как пойдет, начало много обещающее.
Домашнее задание:
1) Послушать еще раз 4 симфонию Брамса (Караяна)
2) Послушать Концерты для Фортепиано Камиля Сен-Санса
3) Докончить наконец свой альбом для Рейки, блин, не знаю как назвать альбом… Советы?
