sysadmin class
by Umarzuki Mochlis
Hi all,
This is probably off-topic but i'm seeking advice about "how can i get 30
students to get a hang of linux system administration while loving it"
They seemed to not remember what i had taught, even the simplest thing like
removing a line while using vim. One thing that i realized that most of
them, especially the boys are pretty must hyped when i taught to gain remote
access to another fedora system with ssh client and you can bet that they
had tried to reboot that ssh server.
Still searching the net about labs related to linux sysadmin and if anyone
want to share their idea, just reply to this post, don't be shy ;)

Google Summer of Code 2010 Light Talk @UTM, 27 March 2010
by Tan Kean Siong
Hi all, Just a event promotion from us, Universiti Teknologi Malaysia Open
Source Software Group.
*
/////////////////////////////////////////////////////////////////////////////////////////////////////////////////
*
**
*Want to write open source code?
Want to make money USD 5000 with you code?
Want to do both?*
Historically, *Google Summer of Code* has brought together nearly 3,400
students with over 200 open source projects to create millions of lines of
code. We’re looking for
students to join in making 2010 the best Summer of Code yet! Every
successful
student contributors will be offered a 5,000 USD stipend, enabling them to
focus on their coding projects for three months.
The Google Summer of Code (GSOC) program is designed to encourage student
participation in open source development. Kicking off in 2005, the program
has several goals:
• Inspire young developers to begin participating in open source
development
• Provide students in Computer Science and related fields the opportunity
to do work related to their academic pursuits during the summer
• Give students more exposure to real-world software development scenarios
(e.g.,
distributed development, software licensing questions, mailing-list
etiquette, etc.)
• Get more open source code created and released for the benefit of all
• Help open source projects identify and bring in new developers and
committers
Student applications will be accepted from March 29–April 9, 2010!
For an exposure about the GCOS 2010, we as UTM Open Source Software Group
will organize the GSOC 2010 Light Talk @UTM. We will invite experienced
participant and also a GSOC mentor, Devtar Singh to explain about the
program, share his experiences and strategy to be selected for the program.
Feel free to attend :
*Google Summer of Code 2010 Light Talk @UTM
Date : 27 March 2010 (Saturday)
Time : 10am - 1pm
Venue : FSKSM N28 BK2 (Level 1),
Universiti Teknologi Malaysia Skudai Campus
*
*Free Admission and open to all undergraduates and postgraduates!*

soft link
by Umarzuki Mochlis
I had created a soft link in user2 to access user1's Desktop
# ln -s /home/user1/Desktop /home/user2/user1-desktop
as root, i can list it (/home/user2/user1-desktop) and access the source
from that link via nautilus. But not as user2
i'm using fedora 12, but i cannot reproduce the same problem on my debian 5
and i had already disabled selinux (if it is related at all)

Re: [fedora-my] [ubuntu-my] Memasangan KVM Dalam Ubuntu 9.10
by wariola＠gmail.com
Salam semua,
Mengenai komputer nombor 1 tu, jikalau nk install atas hardware yang tidak
support hardware virtualization (selepas grep cpuinfo) mmg boleh, tapi yang
akan terjadi ialah technology yang akan digunakan bukannya KVM tapi QEMU.
Performance hit utk running QEMU agak teruk dan agak dicadangkan.
Berkenaan processor core 2 duo, bukan semua core 2 duo support hardware
virtualization especially utk notebook. Jadi sila check di laman web Intel
dahulu sebelum proceed. Kadangkala walaupun ada support hardware
virtualization, tp mesti di turn on dalam BIOS terlebih dahulu.
Utk Virtualbox pula, tidak timbul isu compile kernel jika install virtualbox
OSE dalam repo ubuntu. Dia akan take care semua dependencies. Atau gunakan
SUN Virtualbox binary juga agak senang utk compile, cuma kena install kernel
source dan pastikan semua system telah update dan compiler telah ada. Lps tu
restart utk pastikan kernel source dgn current kernel sama sebelum compile.
Commandnya "/etc/init.d/vboxsetup start".
Virtualbox lebih sesuai utk desktop kerana banyak function memudahkan user
share file dgn vm dan host, banyak GUI dan USB pass through yang mudah
(among others.. byk lagi). Sgt digalakkan utk user yang baru install dan
ingin berjinak2 dengan virtualization.
Mengenai XEN pula, ia tidak upstream membawa maksud XEN tidak menggunakan
kernel Linux yang dikeluarkan oleh Linus dan kawan2 tp sebaliknya
menggunakan kernel sendiri. Justeru aplikasi virtual machine yang kita ingin
install mungkin tidak compatible dengan kernel xen jikalau kita belum buat
testing sepenuhnya. Ubuntu juga by default support KVM dan kurang support
kepada XEN. Even utk install Xen dalam Ubuntu / Debian mungkin perlu kena
bootstrapping process terlebih dahulu, yang agak teknikal. Tanpa menggunakan
bootstrap, Ubuntu perlu di install menggunakan hardware virtualization
support juga sama seperti KVM, dan ini menghilangkan advantage XEN yang
tidak perlu hardware virtualization support utk run Linux yang telah
dimodify.
Mengenai perbandingan XEN dan KVM, KVM upstream dan integrate dalam Linux
kernel since 2.6.20. Ia telah di design sbagai kernel module yang boleh di
load dan unload. Berbanding XEN yang perlukan kernel sendiri (dan tiada
tanda2 akan dimerge dgn main kernel dalam masa terdekat), KVM menggunakan
sepenuhnya kelebihan2 dan ciri2 kernel Linux seperti NUMA dan CFS scheduler
dan kernel Linux tidak akan direlease jika KVM module masih belum stabil.
Berbanding XEN, kernelnya menggunakan scheduler sendiri dan kebanyakan tools
sendiri dan tidak sama dengan kernel Linux yang kita biasa gunakan. Ini
perlukan banyak testing utk pastikan sesuatu aplikasi itu compatible dengan
mainline kernel selain dari patching dan komuniti support yang berbeza.
Namun perlu diberitahu bahawa Oracle dan Citrix masih komited dengan XEN dan
masih ada ruang utk development XEN ini di masa akan datang.
Mengenai KVM dan VMWare, KVM di install directly di dalam kernel justeru
seharusnya performance-nya lebih baik. VMware perlu install Hypervisor layer
di atas kernel Ubuntu dan jarak antara Guest kepada kernel adalah lebih
jauh. Namun ini semua teori sahaja kerana saya tidak menggunakan VMWare
server kerana ia tidak open source. Saya hanya berminat dengan teknologi
Open Source.
Ada beberapa aplication-level virtualization yang jauh lebih ringan, namun
mungkin tidak flexible seperti KVM dan XEN seperti LXC, OpenVZ, UML dan
V-server menggunakan teknologi containers. Sila2 la cuba dan berkongsi
dengan semua komuniti di Malaysia :-)
Sekian celahan saya,
-wariola-
