Remote Control your Ubuntu

Managing the Remote Desktop on Ubuntu is quite easy. You can allow users to access your desktop with VNC Viewer utility that is included in Ubuntu pack and can be downloaded for free also in Windows PCs. The Remote Desktop feature is very useful but follow, at least, one important safety tip: when your desktop remote control is enabled, the only defense against attacks is your firewall and it must be properly installed and configured correctly. In any case, do not forget that Remote Desktop still represents a first level security risk.

To tune up the Remote Desktop just follow these simple steps:

– go to System > Preference > Remote Desktop on the Gnome top menu:

– check the first two check boxes for remote to be enabled.

– if you want to connect your PC through the web and a “Your desktop is only reachable over the local network” notice appears, please do not forget to forward Port 5900 to the IP you see a line below in the menu

– in the Security section, when selecting the “You must confirm each access to this machine” check box, you will be needed to be at the computer to allow the other person to access your desktop. If you are trying to remote access one of your own computer, you would want to uncheck this box

– do not forget that the password check box should always be checked and you should enter a real secure password You will be prompted for this password when you try to log on

– for a better safety be sure that an icon will be displayed on the Ubuntu upper bar when someone is connected

“Your Desktop is Only Reachable Over the Local Network”

Strategic market analysis through Twitter – Know your competitors’ strategy and fight them!

1 Reply

Your competitors are on Twitter and they are very active. Good to know but is their strategy really effective? Difficult to know because normally you have not enough time to constantly monitor more than a couple of them. A good market analysis strategy is to read their posts in a certain period of time but Twitter doesn’t keep this easy because you have to spend hours to expand their tweets before have a good view of what information your competitors wrote. Moreover, Twitter allows you to view only the last 3,200 tweets. For this reason I normally use Twitter XL. This online free service allows you to catch and save the last 3,200 tweets just inserting the Twitter name and click on Get Tweets. After a bunch of seconds (or, more often, some minutes) you will have a complete list including the last 3,200 tweets (retweets included) and you can export them in a CSV format. This file can be imported in a spreadsheet (e.g. OpenOffice) and clearly visualized. If you really know what you are looking for, you have a terrific picture about timing, source, contents and trends of the competitor you are monitoring. Not only you can discover when and about what your competitor is more active but you will also know if he/she is using some particular online service to tweet. This data mining tool is recommended for business or just for fun if you are a meddler.

Como arreglar la conexión de red en Kubuntu 10.04

Leave a reply

Hace unos días tuve un problema con mi Kubuntu 10.04 y la conexión de red. Cuando fui por apagar el PC, en lugar de apagarlo le dí a hibernar por error y cuando fui otra vez a encenderlo no tenia conexión de red disponible. Mirando en el icono que informa respecto a la conexión de red tenia un único mensaje que decía: Gestión de Redes Desactivada. Por tanto que yo intentara de buscar la forma de activar el gestor de redes, no encontraba nada y ninguna opción disponible. Después de varios intentos tuve que ponerme a buscar en la Web con mi portátil para ver si encontraba la forma de solucionar el problema. Afortunadamente encontré que el problema surge en cuanto se apague el PC de forma instantánea o como en mi caso por hibernar, por esos motivos parece que NetworkManager no borra el archivo de estado y cuando se vuelve a reiniciar el PC se genera este error. Para solucionar el problema hay que escribir una serie de comandos en el Terminal para borrar e archivo y volver a reactivar el Gestor de Redes. Os añado las líneas de comandos porque puedo garantizar que es una solución realmente efectiva:

sudo service network-manager stop

cd /var/lib/NetworkManager/

sudo rm NetworkManager.state

sudo service network-manager start

How to repair the missing upper panel on Ubuntu 10.04 Netbook

Leave a reply

After my last update I was not able to visualize my upper panel on Ubuntu 10.04 Netbook. After some internet searches and tests I found these two solutions which were useful to me:

Solution A

– right click on the background and choose Change Desktop Background

– go to Visual Effects and click on Normal

Solution B

– ALT + F2 and when in Terminal type

gnome-panel

If you want to save the configuration and visualize the upper panel for the next time you use Ubuntu, please type in terminal:

gnome-session-save

I am sure there are better ways to solve this problem, so if you have suggestion you are free to comment this post. Thanks.

Rediscover Prism by Mozilla (Ubuntu, MAC and Windows tips)

1 Reply

In 2007, when Prism was launched, there were some enthusiastic reviews about this application. Then the widget era began and Prism popularity decreased. Anyway, Prism is still a powerful application for all that people who desire to run their more often used web application saving RAM and CPU resources. Prism, based on XULRunner, is multi platform, easy to use and very flexible. To use it on Ubuntu you can launch the Terminal and type:

sudo apt-get install prism

or using the Synaptics Package Manager (System —> Administration —> Synaptics Package Manager). Then go to Applications —> Internet —> Prism and a small windows appears. Now, fill in all the required information: the web application URL, the name you prefer, settings and do not forget to click on the Desktop shortcut option. At this point you will find a new rough icon on your Desktop with the name you chose. The first time you use it, with the right mouse button click on it and go to Properties —> Permissions and Allow executing file as program. If you want to change the icon you have to click on it (with the right mouse button), go to Properties —> Basic and choose your favorite icon clicking the icon on the upper left corner. If all are steps are annoying for you, it is possible to use Prism as add-on for Firefox. In this case, on Firefox, go to Tools —> Add-ons —> Get Add-ons and type Prism on the search bar. You will install Prism as a simple add-on for Firefox. Now, you can automatically generate a Prism application just clicking on Tools —> Convert Website to Application when you are in the web application page.

On Windows or MAC we suggest to download the standalone package directly from the official web page or install Prism as Firefox add-on following the same steps we described for Ubuntu. If you use the Prism standalone package you have to decompress it in your favorite location. For Windows users: when you set up a new Prism application, try the tray menu option but do not forget to click on the Desktop shortcut or you will not be able to find again the application after you close it.

In my experience, Prism is really useful with all the Google web applications, with Zoho services and Pandora. Try and enjoy it!
