$ wget http://97.74.56.125/free/xephem-3.7.4.tar.gz

$ tar -xvf xephem-3.7.4.tar.gz

Before compiling, we need these packages installed.

$ sudo apt-get install libmotif3 libmotif-dev x11proto-print-dev libxp-dev libxmu-dev

If you don’t install these packages, you’ll get errors during compilation from various files, like aavso.c

Now let’s compile!

$ cd xephem-3.7.4/GUI/xephem

$ make MOTIF=../../libXm/linux86

(NOTE : If you’re using an x86_64 system, use MOTIF=/usr/lib as make the option since the libXm delivered with xephem won’t do any good for you)
The rest is as stated in the INSTALL file.

du -h | grep -v ‘/’ | awk ‘{print $1}’

Softwares Demonstrated:

1.) Rhythmbox:
The default music player in most GNOME distributions. It supports most music formats, and brings in features such as Podcast support, iPod support, and syncing with Online Radio Stations

2.) Amarok:
The de facto player in KDE based distributions, it is a hot favorite with many people, owing to its large support base, excellent features such as Scripting, Online Music Store support, and support for a large number of audio devices.

3.) Banshee:
It is another GNOME player, developed by Novell. Its interface is quite similar to Rhythmbox. It supports both audio and video formats, and has a large plugin base. Some notable plugins are Youtube videos, Multimedia Key Support among others.

4.) VLC:
VideoLAN Client or VLC has been a popular player due to the fact that it plays almost all known formats, with its large codec set. It is also known for its stream content playback, which was its original purpose. It is by far the preferred player by many for video playback.

5.) Brasero:
The default CD/DVD burning application in most GNOME based distributions. It has a minimalist approach, so users of Nero and other softwares will feel completely at home.

Here we will take a scenario of mounting a new drive ?backup to store backup of your system..

***WARNING*** ***WARNING*** ***WARNING***

” What ever you do make sure to NOT use the command “fdisk /dev/sda” or “fdisk /dev/hda” as that means you are editing your main and boot partition ”

So let us begin..

Quote:

First run fdisk to look at your available disks.

# fdisk -l

Disk /dev/hda: 80.0 GB, 80000000000 bytes
255 heads, 63 sectors/track, 9726 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 268 2048287+ 82 Linux swap
/dev/hda3 269 9726 75971385 83 Linux

Disk /dev/hdc: 80.0 GB, 80000000000 bytes
255 heads, 63 sectors/track, 9726 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System

What we see above is two separate disks, one being hda and the other is hdc. The hda is the main boot drive which should not be played with !

Quote:

The second step is to format the drive. ( If the drive is hdb, hdd, sdb, sdc, sdd simply replace it with “hdc” )

#fdisk /dev/hdc

-press “n” for new partion
-press “p” for primary partition
-press “1″ for the first partition
-press enter for the first AND last cylinders. This will make it automatically use the entire disk
-press “w” for write out to save what you have done

The next step is to make the file-system readable by Linux. You need to format it using ext3 which is widely used file-system .

#mkfs.ext3 /dev/hdc1

Note that I have used “hdc1″ because it is the first partition. Now we are going to set the disk to automatically be mounted on boot as /backup.

Quote:

#mkdir /backup

#vi /etc/fstab

Add the following line:
/dev/hdc1 /backup ext3 defaults 1 1

Verify if this new drive is mounted.

#mount /backup

Here is a non-exhaustive list of the interesting points to know:

* You don’t have to own a Windows® license to use PlayOnLinux.
* PlayOnLinux is based on Wine, and so profits from all its possibilities yet it keeps the user away from its complexity while exploiting some of its advanced functions.
* PlayOnLinux is a free software.
* PlayOnLinux uses Bash and Python

Nevertheless, PlayOnLinux has some defects, as every piece of software:

* Occasional performances decrease (image may be less fluid and graphics less detailed).
* Not all games are supported. Nevertheless, you can use our manual installation module.

Install PlayOnLinux in Jaunty/Intrepid/Hardy

Method 1 (Using repository)

For Karmic Users

First you need to add the PlayOnLinux repository using the following command

Method 2 (Using .deb File)

Download .deb file from here

Install .deb package using the following command

sudo dpkg -i PlayOnLinux_3.7.deb

If you want to know more about how to use check the official documentation

1. To Configure HTTP Server, We should check httpd package installed or

-> To check , #rpm qa httpd* and press enter, if it is installed following line will show,

httpd-2.2.3-11.el5

httpd-manual-2.2.3-11.el5

2.Then, go to this path (/etc/httpd/conf), and open the configuration file called httpd.conf by using vi editor

#vi httpd.conf

3. come to bottom of file , then write script for documnt root folder

systax will be like this,

DocumentRoot /var/www/html/

servername localhost.localdomain.com

For Example

DocumentRoot /var/www/html/ -> this where you saved your html file

ServerName localhost.localdomain.com -> this is your webserver full name ex, linux.fedora.com

4.then save the fileby using :wq command

5. then start the httpd service by using thus command

#service httpd start

the service will start

6.Then , to check service is on or off normally when service start it will automatically on , if it is off by using this command

#chkconfig httpd on

to view ,

#chkconfig –list on ,then service willbe on.

7. Now. Create on html fileunder /var/www/html/ by using vi editor and save through :wq command.

for example ,

#vi hello.html

to check , open mozill browser and enter http://full domain name/webpage name

ex, http://192.168.1.1/hello.html

now it will show what you written in hello html file.

To shutdown / poweroff Ubuntu Linux

Type the command:

sudo halt

OR

sudo shutdown -h now

OR

sudo shutdown -r now

OR

sudo init 6

To reboot Ubuntu Linux

Type the command:

sudo reboot

More information can be found about these two commands by typing following commands (man page):

man reboot
man shutdown

Install the CVS server:
sudo apt-get install cvsd

When prompted in the cvsd installation process for Repository, type in “/cvsrepo”.

Now that the cvsd installation in complete goto /var/lib/cvsd
or seeking for a change(or if there is a new version of cvs updated):

sudo cvsd-buildroot /var/lib/cvsd
If the folder cvsrepo does not exist, then create it ..
sudo mkdir cvsrepo
sudo chown -R cvsd:cvsd cvsrepo

and then initilize the repository
sudo cvs -d /var/lib/cvsd/cvsrepo init
create a user and password
sudo cvsd-passwd /var/lib/cvsd/cvsrepo +username
sudo vi //var/lib/cvsd/cvsrepo/CVSROOT/config
Change “SystemAuto=no”

Test

cvs -d :pserver:username@localhost:/cvsrepo login

cvs -d :pserver:username@localhost:/cvsrepo checkout .

to run it, type

gkrellm &

and you’ll get several info about your computer in real time.

Gkrellm supports themes, so the app can have several appearances. I always use the “invisible” theme, which is a transparent theme, so you can see the background. Very cool. To install a new theme (Ubuntu) go to

http://www.muhri.net/gkrellm/

and download the theme you like. Most of the themes come gzipped. Once you download the theme to your home directory, ungzipp it and move the whole directory to ~/.gkrellm2/themes.

sudo apt-get install libk3b2-mp3

and you are done!!
