Ubuntu Poetable For Windows

I find "Portable Ubuntu for Windows" by accident. He was linked in a thread at Ubuntu Forums strange :

Can’t run native Linux applications in XP, PLEASE HELP. (See post # 45 )

The home page is here : Portable Ubuntu for Windows (sourceforge)

No, this is not dual booting Ubuntu from a flash drive, it is portable virtualization the runs in user space (no administrative access required).

Portable Ubuntu for Windows is CoLinux with an Ubuntu 8.04 (desktop) image and Xming. Colinux is bare metal (low overhead, no fancy gui or management tools) virtualization for Windows. Xming is a X server for windows (cygwin would be an alternate X server).

Colinux home page
Xming home page

OK, I am familiar with CoLinux as I had taken it for a spin a few years ago. Time to take a second look at CoLinux and see what, if any progress had been made.

Portable Ubuntu, once the archive is decompressed, takes about 2 Gb of space on your hard drive/Flash drive.

The improvements are (in no particular order) :

The biggest improvement, IMO, is that Colinux and Xming are portable as advertised. They are distributed as a set of binaries and DO NOT require either installation onto the Windows host or administrative access.

Networking is obtained via NAT but does not require a TAP or change your Windows Network configuration. Again the Networking is all run in “user space” and does not require administrative access on Windows. iptables works well on the guest if you wish to firewall the guest. Ping does not work on the guest.

The Ubuntu guest runs on 256 Mb RAM. Despite this small amount of RAM it actually runs quite fast (from hard drive, slower if you run it from a flash drive). You could add swap disk if you wish (I have not done this yet).

The Ubuntu image can be increased in size from the Windows command line.

Integration between guest and host is outstanding. First there is a shared clipboard (on Xming) and copy-paste between host and guest works well, although in most applications you have to use the menu to copy and paste as the keyboard and mouse short cuts often fail. Sound integration also works out of the box and I was able to stream audio (radio stations) using audacious in Ubuntu and the sound was quite good on the Windows host.

Last file sharing is a snap. The Windows C:\ drive is mounted in the Ubuntu guest. No need for samba, NFS, ssh, ftp, etc to share files between host an guest. I was able to open documents on the Windows host, edit them, and save the changes with both gedit and Abiword (OpenOffice is NOT included on the Ubuntu image).

Conclusion: As you can see, I was impressed with the improvements in CoLinux since the last time I took it for a spin. Portable Ubuntu for Windows is a Open Source option which allows bare metal virtualization on Windows without requiring either installation onto the Windows host or administrative access.

Recover Deleted File in Ubuntu With Foremost

Foremost is a forensics application to recover files based on headers, footers, and internal data structures. Foremost can work on image files, such as those generated by dd, Safeback, Encase, etc, or directly on the drive. This brief article shows how you can use primarily to restore files that have been deleted.

File formats are supported as follows:

jpg - Support for the JFIF and Exif formats including implementations used in modern digital cameras.
gif
png
bmp - Support for windows bmp format.
avi
exe - Support for Windows PE binaries, will extract DLL and EXE files along with their compile times.
mpg - Support for most MPEG files (must begin with 0x000001BA)
wav
riff - This will extract AVI and RIFF since they use the same file format (RIFF). note faster than running each separately.
wmv - Note may also extract -wma files as they have similar format.
mov
pdf
ole - This will grab any file using the OLE file structure. This includes PowerPoint, Word, Excel, Access, and StarWriter
doc - Note it is more efficient to run OLE as you get more bang for your buck. If you wish to ignore all other ole files then use this.
zip - Note is will extract .jar files as well because they use a similar format. Open Office docs are just zipâd XML files so they are extracted as well. These include SXW, SXC, SXI, and SX? for undetermined OpenOffice files.
rar
htm
cpp - C source code detection, note this is primitive and may generate documents other than C code.

You can tweak /etc/foremost.conf to add support for file types. Please note that there is no guarantee that the future will be successful in recovering your files, but at least have the opportunity.

Install Foremost

In Debian and Ubuntu, Foremost can install by using the following command:

$ Sudo apt-get install Foremost

Using Foremost

To find out the use of perintan Foremost, type the following command:

$ man foremost

For example, you delete a jpg file:

$ Ls-l
total 324
-rw-r - r - 1 ugos ugos 324383 2008-02-19 01:25 ugos.jpg

Rm-f $ ugos.jpg

Step recovery is as follows:

$ Sudo Foremost-t jpeg-i /dev/sda1

Recover the results in the output directory in your home directory:

$ Ls-l output /
total 8
-rw-r - r - 1 root root 714 2009-03-12 18:02 audit.txt
drwxr-xr - 2 root root 4096 2009-03-12 17:57 jpg

Before the next run Foremost direktoi the same, you must men-delete/rename the output / directory (as Foremost will not run if there was the same file in the directory) or by using the options However-T (timestamp) so you does not need to men-delete/rename:

foremost $ pdf-t-T-i /dev/sda1

Upgrade Ubuntu 8.10 Interpid To 9.04 Jaunty (Network Upgrade)

Ubuntu (Jaunty) or 9.04 ubuntu ubuntu is the latest version of ubuntu 8.10 (Hardy). Before you begin upgrading ubuntu ubuntu 8.10 to 9.04

You can only directly upgrade to Ubuntu 9.04 Beta from Ubuntu 8.10

Before You Start

You can only directly upgrade to Ubuntu 9.04 Beta from Ubuntu 8.10 (see UpgradeNotes).
Be sure that you have all updates applied to Ubuntu 8.10 before you upgrade.
Before upgrading it is recommended that you read the release notes for Ubuntu 9.04, which document caveats and workarounds for kn
own issues in this version.

If you have a version of Ubuntu which was released before Ubuntu 8.10, please see UpgradeNotes for information on how to upgrade.

Network Upgrade for Ubuntu Desktops (Recommended)

You can easily upgrade over the network with the following procedure.

1. Press Alt-F2 and type update-manager --devel-release

2. Click the Check button to check for new updates.

3. If there are any updates to install, use the Install Updates button to install them, and press Check again after that is complete.

4. A message will appear informing you of the availability of the new release.

5. Click Upgrade.

6. Follow the on-screen instructions.

Network Upgrade for Ubuntu Servers (Recommended)

Install update-manager-core if it is not already installed:
```
sudo apt-get install update-manager-core
```
Launch the upgrade tool:
```
sudo do-release-upgrade --devel-release
```
Follow the on-screen instructions.

Upgrading Using the Alternate CD/DVD

Use this method if the system being upgraded is not connected to the Internet.

Download the alternate installation CD
Burn the ISO to a CD and insert it into the CD-ROM drive of the computer to be upgraded.
- If the ISO file is on the computer to be upgraded, you could avoid wasting a CD by mounting the ISO as a drive with a command like:
- mount -o loop ~/Desktop/ubuntu-9.04-beta-alternate-i386.iso /media/cdrom0
A dialog will be displayed offering you the opportunity to upgrade using that CD.
Follow the on-screen instructions.

If the upgrade dialog is not displayed for any reason, you may also run the following command using Alt+F2:

gksu "sh /cdrom/cdromupgrade"

Or in Kubuntu run the following command using Alt+F2:

kdesudo "sh /cdrom/cdromupgrade"

Upgrading from a Torrent

If you're familiar with torrents and have an ISP that doesn't limit them, you can download the upgrade much more quickly. You'll also be sharing your bandwidth with other Ubuntu users and helping to reduce the load on the servers, which is especially beneficial on release days when the server overload causes problems.

Just visit http://releases.ubuntu.com/jaunty/, and download the appropriate torrent file for the alternate installation CD, found in the list towards the bottom of the page. (It will have a filename like ubuntu-9.04-beta-alternate-i386.iso.torrent.) Load it into your BitTorrent client, and after it is done downloading the ISO, follow the alternate CD upgrade instructions.

Detailed instructions here and here.

Install Google Earth On Ubuntu 8.10 Intrepid Ibex

Installing Google Earth for Adding Repository necessary, follow the steps below: Set up the Medibuntu Repository

As mentioned above, the first thing you need to configure is adding the Medibuntu repository. Setting up this third-party repository can be done with a few quick commands:

$ http://www.medibuntu.org/sources.list.d/intrepid.list sudo wget-O /etc/apt/sources.list.d/medibuntu.list

$ sudo aptitude update & & sudo aptitude install medibuntu-keyring & &
$ sudo aptitude update

This will add the Medibuntu repository, import the Medibuntu GPG key and make new packages available.

Installing Google Earth

To install Google Earth, then simply use:

$ sudo aptitude install googleearth-4,2

You should now have Google Earth added to the "Applications> Internet" menu and, assuming your video card supports the requirements, you are almost ready to travel the planet! Depending on the video card you may want to disable the atmospheric rendering, which can greatly increase performance. This can not be done by setting the following:

View> Atmosphere

If, for some reason, Google Earth does not load properly or crashes on your computer may try to return to the old version that seemed to have a little problem. To do that and try to remove 4.3 version 4.2:
