To enable remote desktop on a VirtualBox machine, you have to follow these steps:
VBoxManage modifyvm MachineName -vrdp
This command enables rdp on the virtual machine
VBoxManage startvm MachineName -type vrdp
It starts virtual machine, listening for rdp request on port 3389 (default port)
rdesktop-vrdp localhost
Connects virtual machine with rdp (You can use rdesktop too).
If you want to change rdp port, use this command:
VBoxManage modifyvm MachineName -vrdpport
Also, enabling authentication for rdp is possible:
VBoxManage modifyvm MachineName -vrdpauthtype null | external | guest
VBoxManage is the command line interface of the VirtualBox.
You can make these settings with GUI: Settings -> Remote Display -> Enable VRDP Server
If you want to use your virtual machine with vrdp only, you can use this command simply:
VBoxHeadless -startvm MachineName
Note: RDP server is not included in Open Source Edition of the VirtualBox. If you want to use this feature, you have to use closed-source edition.

In the past three months Firefox was updated more than we were used in the past also because it had some “speed problems” expecially on Ubuntu 10.04. Now, after the last updates, Firefox seems to go fast but for people who like to try some hacks we have collected some tips from the web:
- start Firefox
- in the address bar type about:config
- find and modify these lines:
- network.http.pipelining > Make it True
- network.http.pipelining.maxrequests > Make it 8 or 10 (we made it 30 and it really works fast especially on websites as ebay)
- network.http.proxy.pipelining > Make it True
- network.dns.disableIPv6 > Make it True
- last but not least restart and Firefox should work fine and a little bit faster.
Before trying these changes, please consider that changing advanced settings on Firefox can be harmful to the stability, security and performance of the program. Take notes of all the changes you are doing in case you need to revert them later.

Today, in our Linux Page (in Spanish) we posted a post about Ophcrack: a Linux Live CD which allows you to recover your Windows password when you forgot them. Sincerely, the described above situation is not common but it could really happen especially when you do not use a PC for some time or if you want to help a friend who is not so skilled with its own computer. Ophcrack is easy to use, sufficiently fast and effective. I tested it to recover some passwords on an old laptop and the results were very interesting; in fact I was able to recover password from accounts I totally forgot to own. Useful! This post has been written just for informative purpose! Please, remind that you are directly responsible for any law violation you commit in case of misuse of the information contained above.
Something to know before the release of Firefox 3.5: how to disable the geo-locating feature. June 28, 2009

This week in our Freeware Page we we have written a quick post about disabling geo-locating feature in the upcoming Firefox 3.5. I have always been an enthusiastic supporter of Firefox because I think it is so flexible that I can find any add-on I need for any purpose. I am also sure that the new Firefox 3.5 will be the perfect tool for my everyday navigation but there is something I am a little bit annoyed. In fact, the Firefox 3.5 will contain a default feature (which can be triggered remotely by a website you are visiting) declaring your geo-location everytime you connect to a site. This feature (previously known as project Geode by Mozilla Labs) could be useful for people involved in social networking but it is a potential wasting time feature for all the others. In fact, you have to declare if you want to automatically display your geo-location each time a website triggers this feature. For this reason, if you are not a social network addict, my personal advice is to disable this geo-locating feature as soon as you install (or update to) Firefox 3.5… (it continues in the Freeware Page).

GSmartControl is a multiplatform (Windows, OS X, Linux) freeware drive health inspection tool which is very useful in all that case when you think something is not working perfectly on your HD. Today, in our Linux Page (in Spanish) we have posted a brief comment about this software which basically is the graphical user interface for smartct. The program is very intuitive and easy to use; it automatically detects all your internal HDs (with some external USB disks we had some problems because they were detected as unknown) and let you decide if you want to activate the SMART feature. This particular feature let you “predict certain kinds of failures with certain chance of success” so you have a better chance to avoid HD crashes and all the consequent data loss. If you prefer, clicking on the “Enable Auto Offline Data Collection” the HDs will be tested every four hours without impacting your CPU performance. I would like to focus your attention that GSmartControl is very well developed and it is possible to download many “personalized” versions for all the main Linux distributions, OS X and Windows. Last but not least, do not forget that SMART could predict some HD crashes but it is not 100% safe; for this reason we strongly recommend you to backup your PCs, at least every week!

After more or less a month from its release, the new OpenOffice 3.0 is receiving tons of positive comments. Anyway, this week, in our Freeware page, we have posted some brief notes abut three different extensions which are able to improve your effectivenss in office routines. First of all we have ooo2gd a simple menu bar which allows you to directly upload or download all kind of documents from Google Documents and Zoho. The second one is the Sun PDF Import Extension which has been created to allow minimal but useful changes to PDF documents. After few minutes we were able to make some interesting changes to a complex PDF documents with just a couple of clicks and export the result “into a hybrid PDF file, which is a PDF with the embedded source file asODF “. Last but not least we tested Sun Presentation Minimizer: an effective extensions which cuts the size of presentations reducing, for example, the image sizes. Using Sun Presentation Minimizer you will be able to simply and freely decide what kind of changes you want to make to your multimedia files contained in the presentations. To conclude it is necessary to focus your attention on the feature that also allows Sun Presentation Minimizer to work on Microsoft PowerPoint presentations. In few words we think that these extensions are guaranteed to be 100% satisfactory!!
FEBE and CLEO the best solution to save (and reinstall) your Firefox settings: extensions, themes and bookmarks! February 17, 2008

Today, in our Freeware Page (traditionally in English) we have added an effective post (in Spanish) about FEBE and CLEO: two fantastic Firefox extensions which allow you to backup all your personal Firefox settings. FEBE is a multiplatform add-on (Linux, Windows, and OS X) easy to install and to manage. In fact, the “FEBE Options” is a complete menu where it is possible to choose: what to save, where (destination folders) and frequency of the backups. Personally, I do suggest to change the default options and not to backup your usernames, passwords and cookies using FEBE. In fact, the backup file, a .xpi, could be stolen and easily reinstalled on a third part computer. Last but not least I want to underline the key role of CLEO which allows FEBE to create the installable .xpi file with all your settings. Recommended!
