OpenIndiana

Hi All,

Its pretty sad to talk about the demise of openSolaris thro Oracle.

But we are lucky to have another distro which along with the Illomos project will fork binaries for openSolaris.

Read this below article from the distrowatch weekly news to learn more:

Hope now this grows larger than openSolaris,

dvdrom, dvdrw, cdrom, cdrw devices missing

Hi All,

This is an error from Ubuntu 8.04 onwards. Many a times - you cant mount your cds and dvds in Ubuntu.

It would throw an error stating "No optical drives found" in softwares like K3b etc.

These below steps will solve the problem...

1. Rename this file to any other file and restart
-> /etc/udev/rules.d/70-persistent-cd.rules

2. Here is the command:
mv /etc/udev/rules.d/70-persistent-cd.rules /etc/udev/rules.d/70-persistent-cd.rules.disabled

Dont forget to restart after this command...

Have a great day ahead,

Installing GRUB 1.0 and 2.0

Hi All,

This post explains how to install GRUB 2.0.

Whenever you do a new installation of XP or Win 2000 or now-a-day's hyped Windows 7, your GRUB will be lost.

GRUB stands for Grand Unified Boot Loader.

The installation part of GRUB 1.0 v/s GRUB 2.0 is something different.

So lets go with both the installations. I have already posted the installation procedure for GRUB 1.0 which is actually GRUB 0.98.

I. For GRUB 0.98

1. Find the partition where you have your Linux ext3 (/ partition) installed.
2. If you have a separate /boot, /home, /var and /root/ partitions then the installation procedure for both changes.
3. Now assuming that you have only one single ext3 partition which is /root - we shall proceed from there on:

Step 1: mkdir a
Step 2: sudo mount /dev/sda? a
[Above ? will be the drive partition where you have /root installed]
Step 3: sudo chroot a
Step 4: /usr/sbin/grub-install /dev/sda

That should load the Grub 0.98

Installing GRUB 2.0 (which is 1.98)


Step 1: sudo mount /dev/sd2 /mnt
Step 2: sudo mount --bind /dev /mnt/dev

Step 3: sudo mount --bind /proc /mnt/proc
Step 4: sudo mount --bind /sys /mnt/sys
Step 5: sudo chroot /mnt
Step 6: nano -w /etc/default/grub
[Ctrl + X]
Step 6: update-grub
Step 7: grub-install /dev/sda

I will be posting more on GRUB 2.0 and its features pretty soon.

Keep reading....

LMDE

Hi All,

To all those who know nothing about a Linux Distribution called LinuxMint, here you go: linuxmint.com

But as per my post title "LMDE" - it is an acronym for Linux Mint Debian Edition.

Yes - now its a new distribution from the linuxmint folks. Read more here and download the iso file of about 900Mb from here: http://www.linuxmint.com/blog/?p=1527

But as the blog states - this distro is not compatible with the repos of Ubuntu. !!!

Enjoy LMDE,

.epub

Hi All,

Have you folks ever come across a format by extension .epub?? If no - then its info is here : http://en.wikipedia.org/wiki/EPUB

It is a format developed by IDPF (International Digital Publishing Forum).

This format is being used in most of the recent Ebook readers like Sony Reader, Apple Ipad etc.

For reading such format books in your desktops having Linux Distro, there is a reader called Fbreader.

Install it and enjoy reading.

Oracle 10g XE - 3

Hi All,

This post explains the last part of configuring Oracle 10g XE edition.

Once the rpm or the .deb file is installed, you need to issue this command as root.

1. /etc/init.d/oracle-xe configure

Here after giving this above command, there are some steps to be done:

1. Mention the port number in the first command. This would be the port that you will be using to access the homepage of the server.
2. Leave the default port of 1521 for the net listener.
3. Enter the password for sys. This is the same password for system user as well.
4. Finally hit your browser to http://127.0.0.1:portNo/apex

Here enter sys / system as the user and the password you gave in step 3 above.

Once you are logged in as sys user, create a new user and issue a password to it and as well grant other permissions like creating a table, trigger, schema etc to that user.

Hope this is simple and easy to understand.

Cheers :)

WPA2 encryption setup with Belkin router

Hi All,

I purchased a Belkin N Series router today which has a 1000ft range!!! I needed to configure wi-fi for linux with WPA2 encryption method. 

I could do it pretty easily. This is the way I did.

1. For a complete encryption set-up using Linux - we need something called wpasupplicant.
2. I did not have enough time to do it in this manner.

Right... Here I go...

Do this from your Windows Machine.

1. Put your Belkin cd into the CD tray and wait for the setup to start.
2. If you are not done with the physical hardware setup of the router - then do it first before you proceed from here.
3. Once done.. Click on the security setup and for the 4th or the 5th step out of 7 - you will be asked to select the type of encryption. Select WPA2.
4. Next - after selecting WPA2 - it asks you for a passkey - which is the password to connect to the systems connected through the router.
5. The router takes the passkey and then it restarts itself.

Thats it....

So now if you try to connect to any Linux distros - you would get the availability of this Belkin wi-fi network.You need to enter the passkey to connect to the same then.

Next I will try to configure the full setup using WPAsupplicant. I will post more after that.
