Converting Office Documents !


Now and then, office-type documents need to be converted. The latex users have always been able to produce a variety of formats from the command line, but for the OpenOffice/LibreOffice users, manual labor has been the solution. That changes with unoconv. Now you can convert to most file formats directly from the command line.

Unoconv is handy for many tasks. I commonly use it to convert all documents in a directory to PDFs, or MS Office compatible formats for clients. The beauty of it is that these previously tedious tasks are now one-liners.

If you’re on ubuntu or derivates (I’m on kubuntu) you can install unoconv from the command prompt:

$ sudo apt-get install unoconv

Having done that, you need to start the server half of unoconv.

$ unoconv --listener

Give this a few seconds to settle. It starts an instance of OpenOffice in the background which it ties into. To use this instance of OpenOffice for format conversion, now try the following:

$ unoconv -f pdf *.odp *.odt

This will convert all text documents and presentations to pdfs. There isn’t much control in the process, but if you want the standard output, it is a great help.

When it comes to exporting to MS Office formats, you have slightly more control. You can, for instance, target the format doc, doc6 and doc95, meaning Word 97/2000/XP, Word 6.0 and Word 95 respectively.

The project is alive, so there is good hope to have the final glitches sorted out. The tool spits out a couple of scary warnings now and then, but the documents seem to turn out well.

The conversion is based entirely on OpenOffice’s conversion, so the quality is what you know from there. Since the conversion is automatic, you might have to limit yourself at times. For instance, I’ve learned that not using the arrow connectors, but instead relying on lines, helps in odp to ppt conversion. Also, the ppts produced are not compatible with the very latest MS Office on Mac – but then you can create PDF’s just as easy.

Install And Use Metasploit Framework On Linux


Hello 😉

Metasploit is an application that is used to research the security in your network. The Administrators can test their networks that is made by them. What Their network is found the weakness or not. Many exploit type and payload Who can be used on Metasploit. You are able to use Metasploit on Linux operating system

  1. Download Metasploit : Click Here
  2. copy metasploit file to root or home directory
  3. open the terminal
$ cd /
$ sudo su
$ chmod +x framework-3.5.2-linux-x86_64.run
$ ./framework-3.5.2-linux-x86_64.run
$ msfconsole

Once the installation process is complete, enter “hash -r” to reload your path. At this point all of the Metasploit Framework commands should be in the system path (via symlinks in /usr/local/bin), and the framework can be updated by running “msfupdate” as the root user.

How to Compress and Split Files in Ubuntu 9.10


split_filesIn Ubuntu, the Archive Manager (or file-roller) has make it easy for anyone to compress and zip up a file or folder, but if you have a large file, say 20Gb, and you want to back it up to the CD/DVD, you will find that no amount of compression can you reduce the file size to fit into 1 CD/DVD. In such case, it is a better solution to compress and split the large file into several smaller files and store them separately. This also applies if you want to share a large file on a file-sharing site. Splitting the compressed file into several smaller files will make it easier for others to download.

Let’s say that the large file is a movie file found in /home/username/films/large-file.avi and you want to compress, split and store the smaller files at the folder /home/username/films/split-flies/, this is what you type in the terminal:

cd films/split-files (change the filepath to where you want to keep the split files)

 tar -cvj /home/username/films/large-files.avi | split -b 640m -d – “large-files.tar.bz.”

You will now see several files appearing at the split-files folder, each with file size of 640MB and with filenames large-files.tar.bz.00, large-files.tar.bz.01, large-files.tar.bz.02, etc.

To recover and extract the split files, type

cat large-files.tar.bz.* > large-files.tar.bz
 tar -xvj large-file.tar.bz

and you can get the original file back.

Install Guest Additions for a better VirtualBox experience


In my default setup of Windows XP, on my particular Ubuntu 9.04 box, the installation of Windows XP rendered a perfectly usable desktop with 32 bit colors in 800×600 resolution. This resolution, of course, is not ideal for some situations (such as Full Screen mode). In order to get a higher resolution, along with other features, you have to install Guest Additions. This is a simple process that can be done quickly and yields a much better user experience than the default. So…let’s get to the installation.

Figure 1

Figure 1

Before you attempt to do the installation of the guest additions you have to have your virtual machine up and running. Once that VM is running you will see three menu entries at the top of the window: Machine, Devices, and Help. You want to click on the Devices entry and then click the Install Guest Additions entry (see Figure 1).

What you will see is a warning message instructing you that the Guest Additions CD image could not be found. Fear not, this is normal. Click Yes in order to download the image and then Download to confirm. You will see a progress bar at the bottom left of your VM window.

When that download has finished you will be asked if you want to Mount the image. Click the Mount button to reveal the Sun xVM setup wizard. Click Next in the welcome screen which will take you to the license agreement window. Click the I Agree button (and read the license if you feel so inclined.)

Figure 2

Figure 2

What you are now doing is a fairly straightforward Windows application-like installation. The only “gotcha” during installation will be a warning that the software did not pass the Windows Logo testing. Ignore this warning and click Continue Anyway. Your screen will flicker for a second – don’t worry.

You will see this warning another time when it attempts to install software for the pointing devices.

After that warning the installation will complete and, in typical Windows fashion, you will be required to reboot your virtual machine. Do this. When the reboot completes you will find your virtual machine much easier to work with. Now:

  • You no longer have to capture the mouse pointer.
  • You can set your resolution to a much higher level.
  • You can now copy and paste between guest and host operating systems.
  • You can run Windows in seamless mode.

Seamless mode

Figure 3

Figure 3

Seamless mode is a very interesting trick. What this does is take the elements of Windows out of the VM window and layer them on top of your Linux desktop.

As you can see, in Figure 3, with seamless mode activated all Windows applications have their own window. So in this instance Internet Explorer appears to be running on Linux by itself. And the Windows task bar is resting nicely on top of the GNOME panel.

You toggle between seamless and non-seamless mode by pressing the Hot Key and the “L” key. The default Hot Key is the right Ctrl key.

Final thoughts

This is truly some exciting work. With the help of VirtualBox you can, effectively, have your cake and eat it too (as the saying goes.) Work with Windows applications inside of Linux without needing the help of Wine.
