How to install the java sdk platform NetBeans on ubuntu linux

by

Logo Net beansWhile researching for the best IDE software for the development of java applications is inevitable to meet the new Java JDK NetBeans, on Microsoft Windows machines the installation of this Software is Just a couple of clicks, however not in our Linux box, especially on ubuntu where I had several problems with the Synaptic Package Manager and either with the terminal installer apt-get. The only way to install the NetBeans IDE is through the Sun Microsystems website, personally I used this link … Java JDK NetBeans … that took me straight to the download page. What to do after that is very simple, Step 1 we need to make the Java netbeans installer executable, step 2 we need to run it. To make it executable we need to use the command chmod as root, so:

sudo chmod +x <path to the file>/netbeans

to run it simply:

sudo ./netbeans

N.B. Remember to change your terminal location to the java netbeans location before trying to chmod it (otherwise it just won’t work) and don’t forget the file extension (in this case .bin). Enjoy!

Ah! By the way: for all the “take it easy” linux users there is a package that doesn’t need any installation, you can find it at this link … JDK NetBeans IDE package … to run the NetBeans executable double click on the file /bin/netbeans and run (tip: put this folder in the /opt or /etc directory and create a luncher on your desktop to run it so you won’t need any fight with the java netbeans installer to have the IDE no your Linux Box).

How to install and configure kismet on ubuntu feisty fawn

by

The sniffer Kismet, anti-intrusion software In this little how-to I am going to see hot to install and configure one of the most famous detector, sniffer, and intrusion detection system for wireless networks, Kismet. Kismet recently has been downloaded thousands of times from its website , because of that ubuntu developers decided to make it available for download from the universe repository, this assures the fact that they will keep the packet up to date and that the ubuntu team, is actually looking after and solving dependencies. Before proceeding to install kismet we need to check 2 things: is the wireless card recognised by the system ? does our wireless card support the method monitor ? If you can not answer to any of this question please send a message.Start the installation from a terminal:

sudo apt-get install kismet

Obviously you need to be connected to the internet. After installation we need to configure the kismet server, to do that we need to:

sudo gedit /etc/kismet/kismet.conf

The voice that will make your kismet server run correctly is:

source=type,interface,name[,channel]

It needs to be changed into:

source=ipw3945,eth0,Wireless Card

DONE! Now to run your kismet you need to turn on your wireless card in monitor mode with the command:

sudo iwconfig eth0 mode monitor

After that to run the kismet application:

sudo kismet

To turn off the kismet server you need to write a capital Q and to turn off the mode monitor of your wireless card:

sudo iwconfig eth0 mode managed

MIND: Not all wireless cards come out clean from the monitor mode, in case your wireless does not work properly after switching back to managed mode a restart of your ubuntu linux machine will fix everything.

Come installare e configurare Kismet su Ubuntu Feisty Fawn

by

In questo piccolo how-to andro’ a vedere come installare su una macchina Ubuntu Feisty Fawn uno dei piu’ famosi detector, sniffer, and intrusion detection system per wireless network, Kismet. Kismet dato il numero di download dal sito web e’ stato reso disponibile sul repository universe su ubuntu Feisty Fawn, questo non solo ci fa rendere conto del numero di utenti che lo usano ma anche ci mette al sicuro del fatto che gli sviluppatori ubuntu tengono d’occhio il pacchetto e verificano le compatibilita’ e dipendenze. Prima di procedere con l’installazione di kismet bisogna verificare che abbiamo tutti i requisiti, la scheda wireless e’ riconosciuta da Linux ?, la scheda wireless supporta il modo d’uso monitor ?, se non sapete rispondere a nessuna di queste domande vi consiglio di inviare un messaggio.
Come installare kismet su ubuntu
Passo 1: aprire il terminale,
Passo 2:

sudo apt-get install kismet

Ovviamente bisogna essere connessi ad internet.

Come configurare kismet su ubuntu

Dopo avere installato Kismet si deve configurare, niente di piu’ semplice.
Da terminale:

sudo gedit /etc/kismet/kismet.conf

Il text editor gedit apparira’, adesso potete sbizzarrirvi tra le opzioni ma quella che fara’ funzionare la vostra applicazione sara’ :

source=type,interface,name[,channel]

modificare con :

ipw3945,eth0,Wireless Card

Questo comando dice a kismet di usare il driver ipw3945 (se la vostra card ne usa un’altro sostituite con il nome del vostro), usare la connessione su eth0 (in genere le wireless card sono su eth0) e dare il nome Wireless Card alla card.

Usare Kismet su ubuntu

Per “accendere” il server Kismet bisogna prima utilizzare la nostra scheda in modalita’ monitor, bisogna usare il comando:

sudo iwconfig eth0 mode monitor

dopodiche’ si deve avviare il server con il comando:

sudo kismet

Dopo l’utilizzo del programma non dimenticate di faro lo switch della wireless card in mode managed con il comando:

sudo iwconfig eth0 mode managed

Nota bene: Non tutte le wireless card escono “pulite” dal modo monitor, niente di qui preoccuparsi comunque in quanto “se necessario” un riavvio della Linux box rimettera’ tutto a posto. Per qualsiasi info o problema su kismet o la vostra wireless card non esitate ad inviare un messaggio, non dimenticate di scrivere che macchina avete, la vostra wireless card ed il vostro file di configurazione, specialmente se il problema risulta all’avvio di kismet o se viene indicato il file da configurare.

Home folder, computer, Network and Trash icons on the desktop

by

A dilemma for new Linux Systems users is that the System, Home folder, Network or Trash icon as a default are not on the desktop. To get to the Home folder Unix users (in particular Ubuntu Feisty Fawn fans) need to follow the menu on top and go to:
Places>>Home Folder or System
and for the Trash they have to use not always happily the one on the bottom dock bar.
To have the Links to this folders straight on the desktop you need to activate the menu call for the Configuration Editor in the path : Applications>>>System Tools>>>Configuration Editor.
Step1:
Activate the menu call
Go to System>>>Preferences>>>Menu Layout
There tick the cell in the path : System Tools for the Configuration-Editor.
Now we have the link that will enable us to get to the configuration tool and activate our favourite icons.
Step 2:
Enable the home folder, Trash and system folder on the desktop
Go to the path:
Applications>>>System Tools>>>Configuration Editor
Within the editor follow the path:
apps > nautilus > desktop
There tick what you need on your desktop, Trash icon, Home folder icon, File system or network icon.
There you go, your favourite icons are now on your desktop on your favourite Linux Distro Enjoy Linux
