HOWTO make DVD and CD .iso images using dd or cat in Linux

Please note that making security backups of your DVD/CD:s may be illegal in your country.

for the purpose of making these backups, the programs you need are standard, *NIX programs, and it is a safe bet that you wont need to install anything.
You may also need to have root permissions in able for you to access the DVD or CD devices.

Heres how to back up the device:

with cat:

with dd:

replace /dev/dvd0 with what ever device it is corresponding with your CD/DVD rom player. If you’re unsure, you might find that $ cat /etc/fstab might provide you some useful information.

The two commands above copies the CD rom or DVD to the home folder. Making a image file with the iso 9660 or the Universal Disk Format file system. Please note that neither cat nor dd cares about file system. Dd copies blocks, and cat prints a file to stdout.

I have heard that cat does not copy the mbr record of the devices copied with it, but I know that dd does.

Note that if you’ve made the image file as the root user, you might have to chmod the file, and it might also be nice to change the files ownership

how to loopback mount the .iso file:

replace iso9660 with udp if your mounting a dvd image.

and how to umount it:

or

Unp

Unp is a small perl script which makes extraction of any archive files a bit easier. It support several compressors and archiver programs, chooses the right one(s) automatically and extracts one or more files in one go.

Instalation:
sudo apt-get install unp

Usage:
usage: unp file [file]...
file: compressed file(s) to expand

Use -- to pass arguments to external programs, eg. some tar options:
unp fastgl.tgz xmnt.tgz -- -C /tmp

Special option:
-f Continue even if program availability checks fail
-u For Debian packages:
- extract data.tar.gz after each operation
- extract control.tar.gz in control//
For other archives:
- create directory /
- extract contents there

currently supported extensions and formats are
tar[.gz,.bz2], gz, bz2, Z, ar/deb, rpm, shar, rar, arj, zip, LHa, cab, ace,
tnef, uu (mail, news), mime, hqx, sea, zoo, pmd, cpio, afio, lzop

Problem:
It doesn’t extract files from RAR archives with full path!

Installing NoMachine NX on Ubuntu 7.10

NX allows you to run remote X11 sessions even across slow or low-bandwidth network connections, making it possible to start sessions from clients running on Windows, Linux, Mac OS X and Solaris platforms to servers running, at present, on Linux or Solaris. Note that development for extending server support to Windows and Mac OS X platforms is in progress.

NX, thanks to exclusive X protocol compression techniques and an integrated set of proxy agents, improves the power of the X Window System to transparently run graphical desktops and applications through the network, by reducing round-trips and implementing strict flow-control of data traveling through low-bandwidth links. Even on slow or low-bandwidth network connections, you can get impressive performance thanks to NX’s lazy encoding algorithm and NX’s capability to automatically tune itself to network bandwidth and latency parameters.

Moreover, NX also can connect to remote RDP and VNC servers, relying on the rdesktop and TightVNC clients by encapsulating the RDP or RFB session within the X11 session.

Here’s a screenshot:

An X11 session

Look at the screenshots below to find out how to get started with NX:

First download the files for the server from here.

For Ubuntu, use NX Free Edition for Linux DEB – i386.

You’ll need to download three files: client, node and server.

Change your working directory to the location where you saved the package and install it by running from a console:

For detailed instructions on how to install the NX Client, NX Node and NX Server packages, please look here.
sudo dpkg -i nxclient_3.1.0-2_i386.deb
sudo dpkg -i nxnode_3.1.0-3_i386.deb
sudo dpkg -i nxserver_3.1.0-2_i386.deb

After installing the server, on your Windows computer, download nxclient for Windows and install it.

Once it’s installed, run it, and enter the IP address of your Linux computer to connect, give it a session name for your own reference, and choose your connection speed.

Here you can download the manual or you can view it online here.
