RHT: From Nasdaq to NYSE

2006-12-13T12:43:00.000+08:00

After the Oracle desease several months ago, some of us may think/believe Red Hat is dying and suffering. Nevertheless, today's story proves those clairvoyant-wannabes' prediction might be wrong. RHT now is listed on NYSE (formerly on Nasdaq).

Solaris 10 11/06 Released

2006-12-12T12:31:00.000+08:00

Yay, Solaris 10 11/06 aka Solaris 10 Update 3 has been released. Thanks to OSNews.com for the update :D

Solaris 10 11/06 Released

Sun has released Solaris 10 11/06 today. Internally, we called this "Update 3". The biggie features for this update are Trusted Extensions and Secure by Default. Yes, all of the security features you loved back in Trusted Solaris, are now standard as part of Solaris 10. This isn't just for the feds either. Banks love it. Wall St. loves it. Corporations that need to follow Sarbanes-Oxley love it.

I'm downloading them rite now!

Unbreakable Linux; Red Hat responds

2006-10-29T18:27:00.000+08:00

As expected, Red Hat reacts :D

Excerpt from http://www.redhat.com/promo/unfakeable/

-----8<-----
Red Hat responds.

The opportunity for Linux just got bigger. Oracle's support for Linux reaffirms Red Hat's technical industry leadership and the end of proprietary Unix. It's no accident that Red Hat was chosen #1 in value two years running. Want to know what else we think? Read on.

Red Hat & Oracle Partnership

Q: Does Oracle's recent announcement change Red Hat's partnership with Oracle?

A: No. Red Hat has had a productive 7-year relationship with Oracle. Red Hat will continue to work closely with Oracle to optimize Red Hat Enterprise Linux and JBoss middleware subscriptions for Oracle products, and to support joint customers.

Red Hat & JBoss Subscriptions

Q: Does Oracle's announcement include support for the Red Hat Application Stack, JBoss, Hibernate, Red Hat GFS, Red Hat Cluster Suite, and Red Hat Directory Server?

A: No. Oracle does not support any of these leading open source products.

Hardware Compatibility

Q: Oracle says their Linux support includes the same hardware compatibility and certifications as Red Hat Enterprise Linux. Is this true?

A: No. Oracle has stated they will make changes to the code independently of Red Hat. As a result these changes will not be tested during Red Hat's hardware testing and certification process, and may cause unexpected behavior. Hence Red Hat hardware certifications are invalidated.

Software Compatibility

Q: Oracle says their Linux support includes the same software compatibility and ISV certifications of Red Hat Enterprise Linux. Is this true?

A: No. Oracle has stated they will make changes to the code independently of Red Hat. These changes will not be tested during Red Hat's software testing and certification process, and may cause unexpected behavior. Hence Red Hat software certifications are invalidated.

Binary Compatibility

Q: Will Oracle's Linux support be binary compatible with Red Hat Enterprise Linux so that my applications continue to work?

A: There is no way to guarantee that changes made by Oracle will maintain API (Application Programming Interface) or ABI (Application Binary Interface) compatibility; there may be material differences in the code that will result in application failures. Compatibility with Red Hat Enterprise Linux can only be verified by Red Hat's internal test suite.

Source Code Compatibility

Q: Will Oracle's product result in a "fork" of the operating system?

A: Yes. The changes Oracle has stated they will make will result in a different code base than Red Hat Enterprise Linux. Simply put, this derivative will not be Red Hat Enterprise Linux and customers will not have the assurance of compatibility with the Red Hat Enterprise Linux hardware and application ecosystem..

Updates

Q: Oracle says they will provide the same updates as Red Hat Enterprise Linux. Can they do this?

A: There are multiple requirements to building binary compatible software. One piece is the source code; another is the build and test environment. While Oracle may be able to take the source code at some point after a Red Hat update release, obviously their build and test environment will be inherently different than that of Red Hat Enterprise Linux. For similar reasons, there is no guarantee that the source code for the Red Hat Enterprise Linux update will work correctly when integrated into Oracle's modified Linux code base.

Support & Maintenance Lifecycle

Q: In order to get support and maintenance for Red Hat Enterprise Linux, do you need to upgrade to the most recent version?

A: No. Red Hat subscribers enjoy support and updates for all versions for up to 7 years. Throughout that time, Red Hat provides regular maintenance releases as part of the Red Hat Enterprise Linux subscription. This is supplemented through our support services by a 'hot-fix' process that provides critical bug fixes on a customer-specific basis. Oracle "reserves the right to desupport certain Enterprise Linux program releases" as part of their Oracle Enterprise Linux support policies.

Support Level Flexibility

Q: Does Red Hat allow you to tailor your support level to your workload?

A: Yes. Many customers match their Red Hat Enterprise Linux subscription level to their application SLA requirements. For example, customers may choose a Basic subscription for non-mission critical file and print servers, while selecting Premium subscriptions for database servers. Oracle does not allow this flexibility - their support policy reads: "If acquiring Enterprise Linux Premier Support, all of your Oracle supported systems must be supported with Enterprise Linux Premier Support."

Security

Q: Can Oracle produce timely security updates to Red Hat Enterprise Linux as they stated?

A: No. There will be a delay between the time a Red Hat Enterprise Linux update is issued and the time the source code makes its way to Oracle. There is no guarantee that the source code for the Red Hat Enterprise Linux update will work correctly when integrated into Oracle's Linux code base; this integration and test will take additional time. In the case where the update corrects critical security flaws, Oracle customers may be exposed to additional risk.

Linux Assurance

Q: Red Hat Enterprise Linux has government security certifications including Common Criteria Evaluated Assurance Level (EAL) 4+/Controlled Access Protection Profile (CAPP). Will Oracle's version of Linux inherit these certifications?

A: No. Common Criteria evaluations are conducted on a specific configuration of software and hardware. Any changes to the software such as those Oracle has announced will invalidate certification.

Customer Collaboration

Q: Will Oracle's Linux customers have the same degree of influence over Oracle's Linux as Red Hat's customers do with Red Hat Enterprise Linux?

A: The support we provide for Red Hat Enterprise Linux starts when Red Hat and its customers collaborate in the design of new versions. This collaboration extends through the development, testing, and production deployment of Red Hat Enterprise Linux. Vendors of a derivative distribution are simply not positioned to provide their customers the same collaboration opportunity.

Support Partners

Q: Hardware vendors such as Dell, HP, and IBM provide support for Red Hat Enterprise Linux. How is Oracle's support offering different?

A: Red Hat's hardware partners provide front line support to customers, backed by Red Hat. Red Hat has a close contractual relationship with these partners, which requires training, well defined escalation paths, Red Hat back-line support, and cooperative customer issue management. Our joint customers enjoy the same degree of collaborative participation as any Red Hat customer.

What to make of Oracle vs. Red Hat?
http://www.linux-watch.com/news/NS8026824348.html

Oracle nie pulak memang keras kepala; seboleh-boleh nak jadi "player" dalam banyak bidang. Kalau boleh berbaik-baik dengan Red Hat, wujudkan win-win situation lagi baik. Kewujudan Unbreakable Linux, bukan setakat mengundang pertarungan dengan Red Hat, malah Novell sekali. Mungkin juga Oracle "hangin" dengan Red Hat kerana membeli JBoss, hehe.

Lawan Oracle buat masa ini:
Database - big time (DB2, MS-SQL), small time (MySQL, PostgreSQL, Sybase, Informix)
Application - SAP (tak nampak ada lagi selain SAP yg berani lawan)
*terkini OS - Red Hat Enterprise Linux, SuSE Enterprise Linux (silap-silap mengundang lawan dengan Solaris)

Red Hat Developer Day: A Post Mortem

2006-09-08T15:20:00.000+08:00

My presentation:

need to improve my presentation skill, English/Manglish & interaction skill with audience (I didn't give any presentation since I left MMU - I knew it's not an excuse, hehe)
just realize it's better if i talk either high-availability or load-balancing, not both - just to make things simpler + focus
overall: i rate it as fair (wonder what others say)

Others:

met several Red Hat guys/gals; Ng Hak Beng (former mentor, will be my mentor again. how cliche!), Eugene Teo (#myoss chatter), Sivaram Shunmugam (HPC master) & Quah Hak Teng - enjoy chatting with them
met old friends; Che Zul, Lotso, Airocom/PERNEC staff, Arafat, etc
can't wait to see Xen, Stateless Linux in RHEL 5
can't wait to see JBoss becomes a big player

Streamyx Users - Can You Open Wikipedia?

2006-08-30T00:10:00.002+08:00

Erghhh, Hafiz aka Mypapit & I noticed that Streamyx IP's are unable to access Wikipedia website at present. First, I suspect there is problem with DNS server. After querying, it seems my hypothesis is wrong :D

[root@kuli ~]# host en.wikipedia.org
en.wikipedia.org is an alias for rr.wikimedia.org.
rr.wikimedia.org is an alias for rr.yaseo.wikimedia.org.
rr.yaseo.wikimedia.org has address 211.115.107.162
[root@kuli ~]# host en.wikipedia.org 202.188.1.5
Using domain server:
Name: 202.188.1.5
Address: 202.188.1.5#53
Aliases:

en.wikipedia.org is an alias for rr.wikimedia.org.
rr.wikimedia.org is an alias for rr.yaseo.wikimedia.org.
rr.yaseo.wikimedia.org has address 211.115.107.162

Solution:
-Use Google Cached service. E.g: http://72.14.235.104/search?q=cache:7onl-F7c6PgJ:en.wikipedia.org/wiki/WAP
-Use proxy. I try tor, now i can access Wikipedia website :)
-Use other ISP's. From my observation, Jaring's IP's are not affected with this problem

To our beloved Streamyx users, what is your experience?

Update:
On 30th August 2006, 9.25AM; I'm able to open Wikipedia website. Yay!

Dalam RHEL Ada ReactOS

2006-08-01T18:26:00.000+08:00

Tatkala fikiran melayang memikirkan nasib badan, ternampak si Najib tengah testing ReactOS guna Qemu. Apa lagi, terus mintak ISO & test pada VMware Workstation.

Host OS: RHEL 4 Update 3 ES
Guest OS: ReactOS 0.3.0

Nota:

Semasa install, pilih "Microsoft Windows", bukan "Other" sebagai Guest Operating System (dalam kes aku, Windows 2000 Professional). Jika pilih "Other", ReactOS gagal boot - perlu bereksprimen untuk mencari punca & akibat yang lebih lanjut
Selepas installation selesai, ReactOS akan prompt untuk beberapa driver. ReactOS semacam "hang" pada tahap SCSI driver - tekan "Cancel" untuk selamat
Semasa guna ReactOS, mungkin berlaku kejadian Blue Screen of Death - biasalah tu :) Tiada apa yang perlu dirisaukan, reboot sahaja.

Piranha - another SELinux headache

2006-07-12T23:05:00.000+08:00

Kalau semalam (subuh/awal_pagi tadi sebenarnya) dengan Cluster Manager, malam nie dengan Piranha pulak.....Ermm, harap maklum; ini bukan berkisar pada ikan piranha yang ganas tu ya.

Simptom:
Servis Piranha tak boleh dimulakan

[root@piranha RPMS]# service piranha-gui start
Starting piranha-gui: (13)Permission denied: make_sock: could not bind to address [::]:3636
no listening sockets available, shutting down
Unable to open logs
[FAILED]

Tengok dari /var/log/messages, sekali lagi SELinux memainkan peranan.

Jul 12 23:03:39 piranha kernel: audit(1152716619.496:2): avc: denied { name_bind } for pid=3668 comm="piranha_gui" src=3636 scontext=root:system_r:httpd_t tcontext=system_u:object_r:port_t tclass=tcp_socket

So, apa lagi. Disablekan httpd protection untuk SELinux seperti semalam. Voila!

[root@piranha RPMS]# service piranha-gui start
Starting piranha-gui: [ OK ]

Menurut error messages, seperti ada kaitan dengan SELinux. Maka sepantas kilat, protection SELinux untuk httpd di"disable"kan.

Edit fail /etc/selinux/targeted/booleans & letakkan entri di bawah:
httpd_disable_trans=0

Boleh juga guna utiliti system-config-securitylevel & tandakan pada kotak Disable SELinux protection for httpd daemon

Voila! Servis httpd berjaya dihidupkan. Hasil yang berjaya:

Red Hat and JBoss join together

2006-06-06T09:29:00.000+08:00

Got e-mail from Red Hat.

We are pleased to announce that today Red Hat has completed the
acquisition of JBoss.

As one company, we believe we can change the economics of the industry.
Creating better software faster. Systematically driving out costs and
simplifying IT. And bringing exponential value to customers.

JBoss will become a division of Red Hat with a common business model of
delivering and providing production support of open source software.
Customers will now have access to a single, proven global production
support organization that can service both Red Hat and JBoss customers,
in addition to supplying JBoss offerings through the established global
channels of Red Hat.

We'd like to hear from you, understand what you'd like to see from the
new JBoss division. Please take a few moments to complete our survey:

Hari Ini Dalam Sejarah - RHCE

2006-05-27T01:09:00.000+08:00

Alhamdulillah :)
http://www.redhat.com/training/certification/verify/?rhce_cert_display:certno=804006728020597&rhce_cert_display:verify_cb=Verify

Al-kisah:
Suatu ketika dahulu, pada awal bulan Mei 2002 (Hmmm, masa aku Gamma level kat MMU), aku buka 1 topik di ITTutor untuk berbincang pasal RHCE. Hanya selepas 4 tahun nampaknya baru aku berjaya merealisasikan impian tersebut. Fuhh.....Minggu nie aku mengikuti kursus RH300 di Training Choice - 4 hari RHCE Rapid Track Course + 1 hari RHCE Lab Exam. Di sini aku nak kongsi beberapa pengalaman & tips (rahsia kejayaan eh) untuk dijadikan teladan bersama:

Apa soalan dia eh?
Sorry lah, aku tak boleh bagitau. Dah sign non-disclosure agreement maaa!

Baca & fahamkan FAQ
Dapatkan FAQ tentang RHCE di http://www.redhat.com/training/rhce/rhce_faq.html

Jangan jadi bodoh sombong
Kalau rasa tak tau, bertanyalah kepada RHCI (Red Hat Certified Instructor). Jangan malu nak bertanya, anda tak rugi apa-apa pun dengan bertanya. Berinteraksilah sebaik mungkin dengan RHCI anda. Syukur kerana Mr. Kelvin Lai (RHCI aku) adalah seorang yang amat peramah, cool & suka berkongsi ilmu.

Masuklah kelas RHCE Rapid Track Course
Ya, saya tahu anda sangat 1337 (apa kejadahnya satu-tiga-tiga-tujuh nie, mengada btol). Anda adalah pengguna GNU/Linux yg sejati lagi tersohor, banyak distro anda dah guna (tak mainlah yang senang-senang, of course lah Debian/Gentoo/Slackware). Sesungguhnya RHCE exam adalah berkisar kepada RHEL, dan fokusnya hanyalah pada RHEL. Anda pasti ketemu pengalaman baru dengan memasuki kelas tersebut. Sebelum nie aku rasa macam dah cukup mahir guna RHEL, tetapi rupa-rupanya ia dusta semata-mata. Kelas nie melengkapkan aku dengan pengalaman/masalah yang aku tak pernah jumpa sebelum nie, juga betul-betul mempersiapkan aku untuk RHCE exam.

Apa yang perlu prepare?
Hmmm, korang baca & fahamkan: http://www.redhat.com/training/rhce/examprep.html Anda memilih jalan yang selamat & bijak dengan menuruti segala tips yg disediakan oleh Red Hat. Ok, aku mengaku yang hari-hari (sepanjang masa, siang & malam) aku baca tips tu. Well, I'm succeed :)

Aku nak cram/braindump ajelah, ok tak?
Hah, jangan sesekali nak cram/braindump. Ko engat ini exam yg ada MCQ ke? RHCE exam adalah hands-on & practical, takde gunanya kalau sekadar cram/braindump. Nak buat macam tuh boleh, tapi perlulah disertakan sekali dengan praktikalnya. Anda takkan berjaya kalau sekadar mengingati fakta berkaitan RHEL.

Apa buku yg seeloknya aku guna utk study?
Secara jujurnya, aku tak gunakan mana-mana buku pun :) Aku cuma baca & pelajari dokumentasi RHEL, kemudian praktikan. Di samping tu, handout yg diberikan semasa kelas RHCE Rapid Track Course amatlah berguna :D

Practice Makes Perfect
Memandangkan RHCE exam nie adalah hands-on & praktikal, maka adalah amat baik jika perbanyakkan menggunakan RHEL di dalam kehidupan. Cubalah setup apa-apa server/application yg menggunakan RHEL. Aku sendiri guna RHEL untuk kegunaan desktop/workstation aku. Kiranya "feel" tuh adalah dalam jiwa aku, hehe. Apa benda aku mengarut nie, damn it.

Saya berkerja sebagai System Engineer/Administrator yang banyak menggunakan RHEL, apa prospek saya?
Hmmm, kalau anda berkerja sebagai System Engineer/Administrator yang memang bergelumang dalam RHEL, prospek untuk berjaya amatlah tinggi. Kenapa aku cakap camtu? - sebab aku sendiri kerja hari-hari play around dgn RHEL untuk setup webserver, mail server, cluster etc. So, bila masuk kelas RHCE Rapid Track course aku takderlah terkejut sangat. Masa exam pun aku cuba bayangkan aku berada di client site tengah toubleshoot/install/configure RHEL :)

Perlu ke tahap 1337 untuk dapatkan RHCE?
Nope, never. Aku tak 1337 (damn it, satu-tiga-tiga-tujuh lagi) pun tapi pass jugak :) Yang penting, usaha bersungguh-sungguh. Usaha tangga kejayaan :)

Belajar daripada pengalaman orang lain

Solat Jumaat
Memandangkan hari exam jatuh pada hari Jumaat, maka sedikit perancangan perlu dibuat. Pertama sekali, beritahu RHCX (Red Hat Certified Examiner) atau pihak Training Choice yang anda perlu mendirikan solat & paling awal boleh mulakan exam pada jam 2.30PM. Kat mana nak solat eh? Masjid yang paling dekat dengan Training Choice dah tentulah Masjid KLCC. Lepas selesai solat, aku sampai ke Training-Choice pada jam 2.15PM. Kiranya masa yang aku ada sebelum 2nd section just fine lah.

Acknowledgement:

Pihak pengurusan syarikat yg sudi menaja aku
Training Choice - breakfast + tea break boleh tahan menunya. Nasi goreng + sambal tu memang kaww baik punya. Nescafe & nestum kat pantry dah jadi makanan harian aku untuk 5 hari nie :D Bab makan, memang world class Training Choice nie :)
Kelvin Lai - RHCI/RHCX yang banyak membantu & tak lokek ilmu
Mak & abah - of course, kerana ambil berat & restu
Anis Husna - yg banyak memberi dorongan, tolong kejut, tolong doakan kejayaan & juga yg mula-mula tengok official result aku
Azri, Chan, Indra, Redzwan - rakan seperjuangan semasa training & exam. Nice to see you guys :)

Software Engineer, Google.com

This position is available in Mountain View, CA and Dublin, Ireland.

Are you part ace coder, part adrenaline junkie? Do you have a knack for
seeing a problem and immediately discerning the likely solution? Maybe you
have been coding for years, are bored with the old
design-build-review-test-ship-repeat routine, and yearn for some
faster-paced challenges? Or perhaps you are a seasoned software engineer who
is also a genius at jockeying networks and administering UNIX clusters.

We are looking for top-notch, thrill-seeking Software Engineers to join the
Google.com Engineering team. Google.com Engineers are in the thick of
everything involved with keeping Google running, from code-level
troubleshooting of service anomalies to safeguarding the availability of our
most popular services; from monitoring and response to building new
automation infrastructure to balancing the desire for change management with
the need for stability. All team members must have strong analytical and
troubleshooting skills, fluency in coding, good communication skills and
most of all enthusiasm for tackling the complex problems of scale which are
uniquely Google. We tackle challenging, novel situations every day, and work
with just about every other engineering and operations team at Google in the
process.

In this role you will need:

* Expertise in coding, analyzing and troubleshooting large-scale
distributed systems.
* Experience in a high-volume or critical production service
environment.
* Strong understanding of IP networking, including the ability to
analyze network behavior, performance and application issues using standard
tools like tcpdump.

Qualifications:

* 0-15 years experience.
* 3+ years developing web-based applications.
* Expertise in data structures, algorithms, and complexity analysis.
* Fluency in one or more of: C, C++, Java.
* Fluency in one of more of: Shell, PHP, Perl or Python.
* Ability to handle periodic on-call duty, as well as out-of-band
requests.
* Solid working knowledge of UNIX, preferably Linux.
* Tack-sharp analytical abilities.
* A strong sense of ownership, urgency, and drive.
* Fluent written communication and unusual verbal agility are strong
assets.
* SQL experience a plus, MySQL a plus.
* Experience leading short projects involving outside teams is a plus.
* BA/BS in Computer Science, MS or PhD is preferred.

---------------------------------------------------------------------------

Unix System / Applications Administrator, Google.com

This position is available in Mountain View, CA and Dublin, Ireland.

Are you:

* ...a seasoned Unix jockey, database wizard, performance specialist,
networking guru, and code slinger all rolled into one?
* ...looking for the next cool problem to solve, in a fast-paced and
engineering-driven environment?
* ...into writing scripts which perform practically the entire job you
once held earlier in your career?
* ...entertained in your off hours by taking things apart just to see
how they work? Are you successful putting them back together when you're
done?
* ...excited by the idea of making Google even faster, more reliable,
more available, more - well, Googly?

If you answered "Yes" to more than three of the above questions, you may be
our kind of System Admin! Keep reading.

Google.com team members are involved in every facet of Google's production
site. From design issues to troubleshooting, from performance analysis to
capacity planning, from DNS to networking to application [mis]behavior,
Google.com engineers are ultimately responsible for making sure that Google
always works. We take that responsibility very very seriously, but if you
think you've got what it takes then we're eager to talk with you.

Working in the Google.com team, you will wear many hats for Google's entire
production site: first responder, performance analyst, service architect,
system/database administrator, capacity planner, tools developer, monitoring
expert, and technical evangelist.

In this role you will need:

* Expertise in UNIX system administration, including configuration,
troubleshooting, and automation.
* Fluency in at least one scripting/coding language.
* Experience running high-traffic web services, including requirements
and capacity analysis, service configuration, monitoring and
troubleshooting, and change management.
* Strong understanding of IP networking, including familiarity with the
functionality, operating, and failure modes of common networking devices,
and the ability to analyze network behavior, performance and application
issues using standard tools like tcpdump.

Requirements:

* 3 - 5 years experience with UNIX systems administration (5-15 years
for Senior position).
* Solid scripting skills in Shell, PHP, Perl or Python.
* Proven technical troubleshooting and performance tuning experience.
* Experience in a high-volume or critical production service
environment.
* Ability to handle periodic on-call duty as well as out-of-band
requests.
* Tack-sharp analytical abilities.
* A strong sense of ownership, urgency, and drive.
* Fluent written communication and unusual verbal agility are strong
assets.
* SQL experience a plus, MySQL a plus.
* Experience leading short projects involving outside teams is a plus.
* BA/BS in Computer Science or related field, or equivalent experience.

Sophos Anti Virus 5.0 on RHEL 4

2006-04-07T16:19:00.000+08:00

Pheww, dah lama tak menulis... Semalam dengan jayanya menginstall Sophos Anti Virus (SAV) 5.0 di mesin RHEL 4 nie. Sepatutnya dah lama aku install tapi hanya semalam baru berminat, antara faktor utama aku install:

Kebolehan on-access scanning atau kekadang dikenali sebagai real-time scanning
Web-based GUI untuk configuration

Well, sayang sekali coz RHEL 4 tak disokong untuk melakukan on-access scanning secara default. Ini disebabkan oleh modul Talpa yang mungkin perlu dikompil semula coz aku tak guna OS yang disokong.

Jika anda merasakan IP Address di atas adalah kepunyaan anda; apa yg perlu anda buat adalah potong/buang kemaluan anda kerana anda baru sahaja dinobatkan sebagai PENGECUT/BACUL :)

IP Address di atas telah dikesan melakukan penyalahgunaan di sebuah laman web berdasarkan wiki (wiki-based website). w00t! Salah satu IP Address tu kepunyaan salah sebuah syarikat IT yg tersohor di seantero Malaysia - kita namakan sebagai Syarikat X. Macam nie rupanya perangai pekerja Syarikat X :D Selain daripada kerja meng"defaced" & menyalahgunakan kemudahan wiki, dah takde kerja lain agaknya. Patutlah Syarikat X nie makin hilang kehormatan - shame on you dude! Sudahlah buat kerja bodoh/bangang yg tak berfaedah, pengecut pulak tu. Kalau anda rasa diri anda terlalu 1337, jangan setakat pandai mengutuk & condemn aje, sebaliknya beri kritikan & komen yg membina - jadilah masyarakat yg bertanggungjawab. Hmmm, macam nie lah perangai orang kita.....

-----
Atas permintaan ramai, mari kita saksikan cekupan skrin yang begitu menyayat hati ini.....

Mungkin URL ini dapat menarik ramai pihak:

OK, terima kasih kepada pihak pengurusan SCAN Associates yg memberi kerjasama penuh kepada si mangsa (dalam kes ini, bukan aku yg menjadi mangsa) serta kawan-kawan si mangsa. Terima kasih atas sikap yg prefessional mereka :) Ingat, yg bersalah bukan keseluruhan syarikat tetapi salah seorang staff mereka. Ingatlah pepatah Melayu; kerana nila setitik, rosak susu sebelanga.

Atas persetujuan, blog ini akan tidak lagi menerima komen. Beberapa ayat & fakta yg dirasakan sensitif juga telah disunting. Kepada pemberi-pemberi komen, terima kasih atas segala penulisan anda :) Sayang sekali, ada yg menyamar dengan menggunakan nick orang lain untuk menulis komen. Ewl ~

CodeFest 2006

2006-03-06T18:51:00.000+08:00

Alhamdulillah, selesai sudah CodeFest 2006. Memang banyak pengalaman yg tak ternilai dah aku dapat sepanjang CodeFest nie berlangsung; lebih banyak pengetahuan, lebih banyak kawan & tak lupa terlebih makan :D

Apa pun, ribuan terima kasih kepada Mnajem yg telah "memaksa" aku masuk event nie. Walaupun terpaksa korbankan waktu rehat weekend aku, namun ianya jauh lebih berbaloi daripada melepak tak tentu arah kat rumah tu. Utk event nie, aku ditugaskan untuk membantu translation KDE project, yakni projek Kedidi Emas. Ada beberapa file PO (aku pun tak reti nak describe) yang perlu dihabiskan terjemahannya.

Team kitorang terdiri daripada:

Mnajem (penterjemah kelas pertama merangkap penterjemah tersohor)
Sharuzzaman (penterjemah kelas pertama merangkap penterjemah tersohor)
Arafat (penterjemah kelas kedua bawah)
Irwan (penterjemah kelas ketiga).

Untuk penerangan lain, rujuk ke sini:
http://projects.asiaosc.org/index.php/Malay_LiveCD

Antara hasil yg aku dapat daripada CodeFest:

Belajar macam mana buat translation menggunakan KBabel. Thanks to Sharuzzaman & Mnajem yg bnyk membantu/mengajar aku. Sekarang barulah aku tahu yg kerja-kerja trabslation nie bukanlah suatu yg susah sebaliknya agak membosankan, haha.
Belajar macam mana CVS works
Dapat berkumpul dgn geng-geng MyPenguin99/ITTutor seperti Mnajem, Sharuzzaman, Arafat & Shakir
Terjumpa (actually mmg teringin jumpa lebih awal coz aku "berhutang" dgn dia) dgn org yg membantu aku secara tidak langsung dlm lulus LPIC-1 - kenmin (Ang Kian Ming). Mamat nie boleh tahan lawaknya; lepas dia tau aku nie PenjejakNeraka (expired nick), terus dia claim teh tarik dia, hehe. Nice to see you man, nanti aku datang lah meetup :D
Dapat jumpa geng-geng baru such as Zaloi, Joey, Adli, Mahmud etc (banyak sgt la). Pastu jumpa lagi dgn En. Hamid UiTM - brader nie bila time ada event je mesti bawak student dia. Respeklah sama dia nie :)
Dapat berkenalan dengan developer dari negara luar such Jepun, Korea, Palestin etc.

Antara gambar-gambar semasa CodeFest (in case ada yg nak gambar, sila contact aku):

h2n - DNS/BIND utility

2006-02-14T19:11:00.000+08:00

Hmm, tadi Faizal mintak tolong setup DNS server. Duhhh, lupa pulak.....

Punyalah susah nak cari balik info pasal h2n nie. Setelah puas googling, jumpalah jugak source untuk download tool nie. Download dekat:
ftp://ftp.ora.com/published/oreilly/dns4/dns.4ed.tar.Z

Thanx to this website:
http://www.dns.net/dnsrd/tools.html

Hmm, dlm RHEL 4 nie takdelah pulak uncompress. Nasib baik boleh guna gunzip.
[irwan@kuli ponorogo]$ uncompress dns.4ed.tar.Z
bash: uncompress: command not found
[irwan@kuli ponorogo]$ gunzip dns.4ed.tar.Z
[irwan@kuli ponorogo]$ tar xvf dns.4ed.tar
[irwan@kuli ponorogo]$ ls
ch06.canon.perl ch09.check_del.823.c ch14.check_soa.v4.c h2n-hp
ch07.bstat.494 ch11.bind_debug.perl ch14.check_soa.v8.c h2n.README
ch07.bstat.8 ch11.ip_to_name.perl check_soa
ch09.check_del.493.c ch14.check_soa.perl dns.4ed.tar
ch09.check_del.811.c ch14.check_soa.sh h2n

Let's get it started.....
[irwan@kuli h2n]$ cat option-file
-d magnifix.com.my
-n 10.0.1
-s seladang.magnifix.com.my
-u irwan
-v 8
-H host
[irwan@kuli h2n]$ cat host

10.0.1.3 hyena.magnifix.com.my hyena
[irwan@kuli h2n]$ ./h2n -f option-file

Maka wujudlah beberapa file yg tercipta dari arahan tadi:
[irwan@kuli h2n]$ ls
boot.cacheonly db.127.0.0 h2n host option-file
db.10.0.1 db.magnifix h2n.man named.boot

[irwan@kuli h2n]$ cat db.magnifix

localhost IN A 127.0.0.1
mawas IN A 10.0.1.2
mawas IN MX 10 mawas.magnifix.com.my.
kambing IN A 10.0.1.1
kambing IN MX 10 kambing.magnifix.com.my.
hyena IN A 10.0.1.3
hyena IN MX 10 hyena.magnifix.com.my.

Siap buat reverse lookup tu :)
[irwan@kuli h2n]$ cat db.10.0.1
@ IN SOA kuli.magnifix.com.my. irwan.kuli.magnifix.com.my. ( 3 10800 3600 604800 86400 )
IN NS seladang.magnifix.com.my.

1.1.0.10.IN-ADDR.ARPA. IN PTR kambing.magnifix.com.my.
2.1.0.10.IN-ADDR.ARPA. IN PTR mawas.magnifix.com.my.
3.1.0.10.IN-ADDR.ARPA. IN PTR hyena.magnifix.com.my.

Done! For more info, kenalah baca manual:
[irwan@kuli h2n]$ less h2n.man

Tak Boleh Switch User

2006-01-20T16:52:00.000+08:00

Tadi Mus menggelabah, kata machine yg dia tengah access tu tak boleh switch user dari root -> postgres. Aku buat dari tempat dia tak boleh, buat dari tempat aku pun tak boleh. Erghhh, kacau-bilau betul dunia nie.....

[root@ccas ~]# su - postgres
could not open session

Hmm, tak pernah pulak aku jumpa masalah yg memberi error message camtu sekali.

Ke salah user postgres nie, so aku try su - ke user lain.
[root@ccas ~]# useradd kambing
[root@ccas ~]# passwd kambing
Changing password for user kambing.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.
[root@ccas ~]# su - kambing
could not open session

Huh, tak boleh jugak. Tapi at least aku tau ini bukan masalah user postgres. Baca /var/log/messages takde memberi hint yang berguna pulak :(

Setelah googling, somebody mention pasal home permission. Aku tengok ok je. Entah macam mana datang intuition untuk tengok permission /etc/passwd.
[root@ccas etc]# ls -l passwd
-rw------- 1 root root 2632 Jan 20 15:16 passwd

Uik, semacam jek. So aku try compare dgn machine aku.
[root@kuli ~]# ls -l /etc/passwd
-rw-r--r-- 1 root root 1715 Dec 17 13:18 /etc/passwd

Heh, apa kes lain nie. Maka mulakan hikmat chmod.....
[root@ccas etc]# chmod +r /etc/passwd
[root@ccas etc]# su - postgres
-bash-3.00$ w

Yada, done!

Moral:
Back to basic, kesilapan bodoh boleh berlaku pada manusia yang tak sempurna.

Mesti Tonton: Firewall Movie

2006-01-18T15:44:00.000+08:00

Firewall Movie
http://firewallmovie.warnerbros.com/

Computer security specialist Jack Stanfield (HARRISON FORD) works for the Seattle-based Landrock Pacific Bank. A trusted top-ranking executive, he has built his career and reputation on designing the most effective anti-theft computer systems in the industry, protecting the bank’s financial holdings from the constant threat of increasingly sophisticated internet hackers with his complex network of tracers, access codes and firewalls.
Jack’s position affords a comfortable life for him, his architect wife Beth (VIRGINIA MADSEN) and their two young children – a standard of living that includes a beautiful home in a residential community just outside the city.

But there’s a vulnerability in Jack’s system that he has not accounted for: himself. It’s a vulnerability that one very ruthless and resourceful thief is poised to exploit.

Bill Cox (PAUL BETTANY) has been studying Jack and his family for many months; monitoring their online activity, listening to their calls and learning their daily routines with an arsenal of digital and video recorders and parabolic microphones that tap into the most personal of information. He knows the names of their children’s friends, their medical histories, and the I.D. code for the security station that guards their neighborhood. Having spent the better part of a year methodically infiltrating every aspect of Jack’s identity, Cox is now ready to make good on his investment.

Leading a tight team of mercenary accomplices, he seizes control of the Stanfield house, making Beth and the kids terrified hostages in their own home and Jack his unwilling pawn in a scheme to steal $100 million from the Landrock Pacific Bank.

With every possible escape route shrewdly anticipated and blocked by Cox, every potential ally out of reach and the lives of his wife and children at stake, Jack is forced to find a breach in his own formidable security system to siphon funds into his captor’s offshore account – incriminating himself in the process and eradicating any electronic evidence that Cox ever existed.

Under constant surveillance, he has only hours to accomplish the risky transactions while desperately hunting for a loophole in the thief’s own impenetrable wall of subterfuge and false identities to save his family and beat Cox at his own game.

Hmm, agak-agak firewall apa yg digunakan? iptables, ipchains, ipfw, pf, Checkpoint, Astaro, Cisco PIX, Smartguard, atau lain-lain kah.....
Kalau bawak isteri/girlfriend (yang langsung takde minat dgn dunia IT) layan cerita nie agak-agak diorg boleh terima ke, hehe.

Done!

Komen
--------
Java-based console nie betul-betul makan bnyk resource. Sebab itulah 256MB is the recommended minimum while 1024MB is recommended for best performance on large production system.
[irwan@kuli ~]$ ps aux | grep java.bin
root 21365 3.8 29.4 119308 56244 pts/3 Sl+ 18:54 0:10 /usr/lib/jvm/java-1.4.2-ibm-1.4.2.2/jre/bin/java.bin -ms8m -mx64m -cp .:./base.jar:./mcc10_en.jar:./jss3.jar:./ldapjdk.jar:./mcc10.jar:./nmclf10_en.jar:./nmclf10.jar -Djava.library.path=../lib -Djava.util.prefs.systemRoot=. -Djava.util.prefs.userRoot=. com.netscape.management.client.console.Console -u admin -a http://kuli.magnifix.com.my:9391/

Perhatikan yang memory usage adalah sebanyak 29.4MB.

Wish List
-----------
A web-based console ;)

PenjejakNeraka is now known as ipvsadm

2006-01-02T16:07:00.000+08:00

Hmm, kepada mereka yang mengenali PenjejakNeraka di IRC, dimaklumkan bahawa nick tersebut telah didropkan. Aku sekarang menggunakan nick ipvsadm :) Asas/sebab utama pertukaran tersebut adalah kerana ada yang kurang senang dengan nick lama aku tu, hehe. Antara sebab sekunder adalah; tahun baru, nick baru :)

Ada yang salah anggap seolah-olah:

aku ingin ke neraka
aku guna nick terebut konon nak dianggap ganas dgn nama "neraka"
aku nie orang jahat

Actually aku cuma guna nick tu kerana kagum dengan watak Penjejak Neraka dalam komik Pendekar Laut - tak lebih dari tu. Jadi, utk kesenangan & kebahagiaan semua pihak, eloklah aku tukar nick tu. Aku pun tak salahkan mereka yang memaki hamun aku atas penggunaan nick PenjejakNeraka kerana aku tahu mereka jahil dengan niat sebenar :) Aku pun tak nafikan yang nick PenjejakNeraka nie agak keras bunyinya, hehe.

Selamat tinggal PenjejakNeraka, selamat datang ipvsadm :)

Makan-makan KDE 3.5

2005-12-31T15:09:00.000+08:00

Pada tanggal 27/12/2005 bersamaan 25 Zulkaedah 1426H, Makan-makan KDE 3.5 telah berjaya diadakan di Kedai Sate Hj Samuri, Kajang. Antara peserta yg terlibat adalah seperti Najmi aka Mnajem, Bahathir aka root, Arafat aka Trunasuci, Sharuzzaman, Hasbullah aka Sebol, Haris aka Hafnie, Sharuzzaman & aku sendirik.

Walaupun makan-makan nie rasa aku adalah bertujuan utk meraikan KDE 3.5 tapi topik lain yg lebih bnyk dibincangkan seperti Hosting, Sophos, Kismet, ITTutor etc.

Acknowledgement from Celcom

2005-12-22T14:32:00.000+08:00

Hari Isnin lepas bil Celcom sampai. Seperti biasa, aku pun bayar online thru RHB.

Hari semalam aku dapat acknowledgement daripada Celcom thru SMS yg menyatakan Celcom telah terima payment aku dgn sebaiknya. Terkejut jugak, sebelum nie rasanya tak pernah pulak dapat acknowledgement macam nie.

"Dear Valued Customer, thank you for your payment of RM44.97 via RHB, which has been updated. This message comes to you from Celcom."

Good job Celcom! Keep up the good work :)

Installing Microsoft SQL Server 2005

2005-12-21T15:38:00.000+08:00

Atas sebab-sebab yang tak dapat dielakkan; hari ini aku mencipta sejarah dengan menginstall Microsoft SQL Server 2005.

Memandangkan hanya utk testing, aku pun pilih evaluation version:
http://www.microsoft.com/sql/downloads/trial-software.mspx

Pergh, tak ingat punya besar - 897MB. Nasib baik connection kat sini berdesup, dapatlah download in less than hour dgn speed 300-400 Kbps. Punyalah banyak cekadak dia, nak kena ada Windows Installer 3.1 pulak. maka aku pun downloadlah di sini:
http://www.microsoft.com/downloads/details.aspx?FamilyID=889482fc-5f56-4a38-b838-de776fd4138c&displaylang=en

Lepas install Windows Installer nie (lepas install, kena terus reboot), barulah berjaya install Microsoft SQL Server 2005.

Selamat Tinggal Slackware

2005-12-16T12:35:00.000+08:00

Hmmm. Setelah berbulan-bulan aku tak boot ke Slackware, hari nie aku "terpaksa" berbuat demikian demi memberikan penghormatan terakhir kepada bekas favourite Linux distro aku nie.

root@enlightenmenter:~# uname -a
Linux enlightenmenter 2.6.7 #1 Wed Jun 16 16:23:03 PDT 2004 i686 unknown unknown GNU/Linux
root@enlightenmenter:~# cat /proc/version
Linux version 2.6.7 (root@tree) (gcc version 3.3.4) #1 Wed Jun 16 16:23:03 PDT 2004
root@enlightenmenter:~# cat /etc/slackware-version
Slackware 10.0.0
root@enlightenmenter:~# date
Fri Dec 16 12:54:01 MYT 2005
root@enlightenmenter:~

Lepas nie aku akan bertukar PC & Insya-Allah hanya akan ada RHEL dalam tu. Malas nak letak banyak OS coz aku akan tumpukan RHEL utk segala kerja-kerja aku.

So long Slackware! I'll be missing you.....

It's All About SuSE

Jangan salah sangka, di hatiku masih RHEL & Debian. Cuma kadang-kadang kita kena ambil tahu yang lain-lain.

Ini adalah output kepada "uname -a" (if you're a Unix/Unix-like OS user, you must know what I mean) di shell yang dimiliki secara peribadi (semuanya legal). Too bad, catalina & narcissus tengah kong. Kalau tak, ada lagi 2 :(
