Nama-nama kode Linux Ubuntu

Distro Ubuntu saat ini menduduki posisi kedua versi distrowatch.com sebagai distro yang paling banyak dipakai di seluruh dunia. Salah satu kelebihan ubuntu adalah diterbitkannya versi baru ubuntu setiap enam bulan sekali dan mendapat dukungan dari canonical selama 18 bulan setelahnya. Canonical juga merilis versi LTS (long term support) setiap dua tahun (sesuai jadwal) dan mendapat dukungan (support) selama tiga tahun setelah dirilis. Ini dia tabel lengkap kode nama ubuntu:

Ubuntu menggunakan  kode bulan dan tahun untuk menamai versi nama distro yang mereka rilis. Untuk memudahkan memahaminya inilah ilustrasinya Versi 4.10 artinya versi tersebut dirilis pada bulan Oktober tahun 2004. Kalau sesuai rencana canonical akan merilis versi terbaru ubuntu pada bulan April 2012, kode nama distronya Precise Pangolin.

Precise Pangolin merupakan LTS distro yang akan mendapat support dari canonical dari bulan April 2010 hingga April 2017.

How To : Install Firefox 6 on Ubuntu without Losing The Old Version

How to

install the new Firefox 6 without losing your old version? Actually,  it’s very easy, but it’s not as easy as in Windows.

1. Go to Firefox Beta download page.
2. Download, and make sure that your file is not corrupted.
3. Extract the source file.

$tar xvf firefox-6.tar.bz2

4. Copy to lib directory

$sudo cp -r firefox /usr/lib/firefox-6

5. Create a link to the executable file

$sudo ln -s /usr/lib/firefox-6/firefox /usr/bin/firefox-6

6. Create a link once again

$sudo ln -s /usr/bin/firefox-6 /usr/bin/firefox6

Ok, the Firefox 6 has been installed on your Ubuntu.
Now, the last step is create a app launcher on your Desktop.
Right click on the Desktop->Create Launcher

Boring with Gnome, LXDE, now tasting KDE Plasma

Setelah mencoba Unity 2D (karena graphic card notebook gw gak support 3D) dan mengalami sedikit kebosanan dengan LXDE yang super duper ringan and extremely fast, gw memutuskan untuk beralih sementara ke KDE. KDE yang gw pilih adalah KDE Plasma yang dulunya merupakan default untuk environment netbook.

Not bad at all….Bisa mengurangi kebosanan gw.

Berikut screenshot KDE gw di Ubuntu 11.04 Natty Narwhal :

Lumayan untuk menghilangkan kebosanan.

Unity 2D running on LXDE on the top Ubuntu 11.04

Aneh bin ajaib yah…he..he..

Sebenarnya karena notebook gw gak support Gnome3 Shell Desktop ataupun Unity 3D maka gw tetap pake LXDE di Ubuntu 11.04 gw. Di atasnya gw juga pake Unity 2D (running on startup).

Sebenarnya sih Unity 2D bisa running on my Gnome desktop. Tapi sayang sekali gw kurang suka karena gnome-panel selalu running (akibat dari terinstallnya Gnome3 Shell Desktop). Bisa dilihat disini (http://inaroka.co.cc/?p=220).

Ini screenshotnya :

Ganti desktop dari GNOME ke LXDE

Setelah beberapa menggunakan GNOME yang dimodifikasi menjadi Mac OS X looks, akhirnya gw putuskan untuk mencoba kembali desktop enviroment LXDE. Pertimbangannya adalah masalah dan fragileness.

Beberapa kali aplikasi-aplikasi yang jalan di GNOME gw sering crash termasuk Google Chrome, SAPGUI for Java dan beberapa aplikasi Java lainnya. Memang aplikasi-aplikasi ini cenderung lumayan berat terutama apabila saat Chrome membuka banyak tab. Memory sering habis dan memakan space di swap.

Setelah pindah ke LXDE akhirnya aplikasi-aplikasi tersebut menjadi lebih stabil dan tidak sering crash. Chrome juga barusan diupgrage ke versi 10. SAPGUI for Java masih sama dan menjadi lebih stabil. Jarang terjadi low memory. Konsumsi memory menjadi lebih kecil karena memang LXDE membutuhkan memory lebih sedikit daripada GNOME. Namun GNOME tetap ada dan sebagai main desktop, jika nanti sewaktu-waktu tetap butuh.

Notebook udah pake default desktop ke LXDE dan lebih stabil.

Set date time on Linux Ubuntu via command line

Sometime we need to set our linux date time without having touch the desktop. We can do it via remote ssh / telnet.

Syntax :

#date mmddhhyyyy.ss

For instance, to set the date/time for May 19th, 2007, 6:00pm (and 0 seconds), you would type:

#date 051918002007.00

Now you can set date time via command line.

Installing and Configuring Kerberos, Samba, and Winbind on Ubuntu Server 5

These instructions assume your domain information is DOMAIN (old style domain name) and the DNS resolvable one is DOMAIN.INTERNAL. Our Active Directory environment is running on Windows 2000, but I have tested these instructions in a VMWare Team with Windows 2003 native mode and they worked there as well.

================================================== =======

Installing and Configuring Kerberos, Samba, and Winbind on Ubuntu Server 5

Steps

Step 1: Install the Required Packages

Note: Enter Y when asked if you want to install the additional packages

apt-get install krb5-user
apt-get install winbind samba

Step 2: Edit the /etc/krb5.conf File

Code:
[logging]
default = FILE10000:/var/log/krb5lib.log
[libdefaults]
ticket_lifetime = 24000
default_realm = DOMAIN.INTERNAL
default_tkt_enctypes = des3-hmac-sha1 des-cbc-crc
default_tgs_enctypes = des3-hmac-sha1 des-cbc-crc
[realms]
DOMAIN.INTERNAL = {
kdc = domainserver.domain.internal
admin_server = domainserver.domain.internal
default_domain = DOMAIN.INTERNAL
}
[domain_realm]
.domain.internal = DOMAIN.INTERNAL
domain.internal = DOMAIN.INTERNAL
Step 3: Edit /etc/samba/smb/conf

Notes: Change the NETBIOS name parameter to be correct for the server. Make a backup copy of the original file!!!

1) Make the edits. The configuration shown is the bare minimum and doesn’t share anything.

Code:
[global]
security = ads
netbios name = CMHRG02
realm = DOMAIN.INTERNAL
password server = domainserver.domain.internal
workgroup = DOMAIN
idmap uid = 500-10000000
idmap gid = 500-10000000
winbind separator = +
winbind enum users = no
winbind enum groups = no
winbind use default domain = yes
template homedir = /home/%D/%U
template shell = /bin/bash
client use spnego = yes
domain master = no
2) Test the configuration with the testparm command

Step 4: Edit /etc/nsswitch.conf to look like the example below

Code:
passwd: compat winbind
group: compat winbind
shadow: compat
hosts: files dns wins
networks: files
protocols: db files
services: db files
ethers: db files
rpc: db files
netgroup: nis
Step 5: Modify the PAM settings

1) /etc/pam.d/common-account should contain only the following lines

Code:
account sufficient pam_winbind.so
account required pam_unix.so
2) /etc/pam.d/common-auth should contain only the following lines

Code:
auth sufficient pam_winbind.so
auth required pam_unix.so nullok_secure use_first_pass
3) Modify the /etc/pam.d/common-password file, so the max parameter is set to 50, similar to the one shown below

Code:
password required pam_unix.so nullok obscure min=4 max=50 md5
4) Make sure the /etc/pam.d/common-session file contains the following line

Code:
session required pam_mkhomedir.so umask=0022 skel=/etc/skel
Step 6: Make a directory to hold domain user home directories

Note: Use the value you put in the WORKGROUP tag of the /etc/samba/smb.conf file

Code:
mkdir /home/DOMAIN
Step 7: Initialize Kerberos

1)
Code:
kinit domain_admin_account@DOMAIN.INTERNAL
Next check to be sure you got a ticket from the domain controller

2)
Code:
klist
Step 8: Join the system to the

Code:
net ads join -U domainadminuser@DOMAIN.INTERNAL
Step 9: Restart Samba-related Services (Or reboot the server)

Note: The order is important

Code:
/etc/init.d/samba stop
/etc/init.d/winbind stop
/etc/init.d/samba start
/etc/init.d/winbind start
Step 10: Restart SSH and Test Connectivity

Note: If you rebooted the server in the previous step, just try and login.

Code:
/etc/init.d/ssh restart

ssh useraccount@server
If you can login using your active directory username and password then everything is working!

Step 11: Configure SUDO

1) First create a group in Active Directory called UnixAdmins and add the names of people whom you want to be able to use sudo to admin the server.

2) Next, add the UnixAdmins group to the /etc/sudoers so these users can use sudo

Code:
%UnixAdmins ALL=(ALL) ALL

HELPFUL COMMAND LINES

1) List the derived UNIX GID values for Active Directory groups

Code:
for gid in $(wbinfo -r ); \
do SID=$(wbinfo -G $gid);GROUP=$(wbinfo -s $SID); echo $gid is $GROUP; done
2) See the Active Directory SID for a particular named user

Code:
wbinfo –n

Sekarang jamannya cloud computing, bung !!

Kemaren malem pas online di ym, gue sempet ngobrol-ngobrol dengan temen yang berbisnis di bidang IT. Sekarang dia akan memulai bisnis software nya dengan cara baru called SaaS (Software as Services). Apa itu SaaS ? Jadi software yang didevelop sama dia akan dijadikan semacam service. Customer tinggal membayar biaya sewa. Jasa ini biasanya ada di layanan yang disebut cloud computing alias komputasi awan.

Apa itu komputasi awan (cloud computing) ? Komputasi awan menurut wikipedia adalah adalah gabungan pemanfaatan teknologi komputer (‘komputasi’) dan pengembangan berbasis Internet (‘awan’). Beberapa waktu lalu detik.com juga mengabarkan bahwa Microsoft Indonesia dan Telkom menjalin kerjasama untuk cloud computing ini. Microsoft menyediakan software dan aplikasinya sedangkan Telkom menyediakan infrastruktur dan support nya. Temen gue yang ini juga ditawari Microsoft untuk kerjasama cloud computing ini.

Gue sendiri baru baca-baca untuk cloud computing dengan menggunakan Ubuntu. Kebetulan Ubuntu mulai versi 9.04 Jaunty Jackalope sudah menyediakan fitur cloud ini dengan software dari Eucalyptus. Selain itu, kompatibel juga dengan Amazon EC2.

Well, biar gak ketinggalan teknologi (wajib neeh soalnya…), sudah saatnya gue meng-update knowledge about cloud computing ini

Install OpenOffice 3.2.0 di Ubuntu 9.04 Jaunty

Firstly, go to the OpenOffice website: http://download.openoffice.org/ and download the Linux .deb file.

1 – Once you have done that, extract the .deb file,

Quote:

OOo_3.2.0_LinuxIntel_install_en-US_deb.tar.gz

Then you’ll see a file called OOO320_m12_native_packed-1_en-US.9483

2 – You can remove the existing version of OpenOffice if you wish with this command:

Quote:

sudo apt-get remove openoffice*.*

3 – Copy and paste OOO320_m12_native_packed-1_en-US.9483 onto the desktop then open Terminal and paste this command:

Quote:

sudo dpkg -i ~/Desktop/OOO320_m12_native_packed-1_en-US.9483/DEBS/*.deb

4 – Then paste this command:

Quote:

sudo dpkg -i ~/Desktop/OOO320_m12_native_packed-1_en-US.9483/DEBS/desktop-integration/openoffice.org3.2-debian-menus_3.2-9472_all.deb

Once you’ve done that you’ll find OpenOffice 3.2 in Office.

Installing and Running Aptana on Ubuntu 8.10 (Ubuntu Intrepid)

Since Linux distributions started shipping with Firefox 3 Aptana has become harder and harder to get running error free. After getting a nice fresh Ubuntu 8.10 install running my first task was to get Aptana running so that in a pinch I could belt out some code and get myself paid.

There are only a couple of steps required to get Aptana running on Ubuntu 8.10. Install Java and install Firefox 2. Don’t panic I have never had trouble doing this despite the warning bells you are probably hearing. Firefox 2 and 3 can happily be installed on the same machine without argument.

Step 1: Install Java on Ubuntu

Simple, hardly requires a step.

1. Go to Applications -> Add/Remove
2. Change the Show drop down to read “All Available Applications”
3. Search for Java
4. Tick and Install Sun Java 6 Runtime – feel free to use one of the others, your choice but I can’t vouch for them working – Aptana says they prefer Sun and that is good enough for me.

Step 2: Install Firefox 2 on Ubuntu 8.10

The theory here is simple. Change your package sources to Ubuntu 7.10 (Gusty Gibbon) ones, which make Firefox 2 available, install Firefox 2, and then revert your package sources.

Back up our existing source list to make it easy to revert later.

sudo mv /etc/apt/sources.list /etc/apt/sources.list.original

Create a new package source list

gksudo gedit /etc/apt/sources.list

Paste the following list of package sources into this new file and save and close it.

deb http://archive.canonical.com/ubuntu hardy partner
deb http://br.archive.ubuntu.com/ubuntu/ hardy main universe restricted multiverse
deb http://security.ubuntu.com/ubuntu/ hardy-security universe main multiverse restricted
deb http://br.archive.ubuntu.com/ubuntu/ hardy-updates universe main multiverse restricted
deb http://packages.medibuntu.org/ hardy free non-free

Update using the new (well technically old) package source and install Firefox Two.

sudo apt-get update
sudo apt-get install firefox-2

Step 3: Cleaning up the mess and getting the system back to usable

Copy back our original package source list

sudo mv /etc/apt/sources.list.original /etc/apt/sources.list

Update your package sources for next time.

sudo apt-get update

Step 4: Downloading and Running Aptana on Ubuntu 8.10

1. Download Aptana from http://aptana.com/studio/download
2. Create a script to launch it with the correct settings
   1. Create a new text file called startAptana in your home directory
   2. Add the following

   3. #!/bin/bash
      export MOZILLA_FIVE_HOME=/usr/lib/firefox
      /usr/local/aptana/AptanaStudio

   4. Make the file executable by running

   5. sudo chmod a+x startAptana

   6. from the Terminal

All things being equal you should now be able to ./startAptana and away you go.

Troubleshooting

If you get Java errors and can not find JRE messages change

/usr/local/aptana/AptanaStudio

to

/usr/local/aptana/AptanaStudio -vm /usr/lib/jvm/java-6-sun-1.6.0.10/jre/bin/java

(or whatever the path to your Java runtime is) in your startAptana file
