In this post I will explain the ways we can configure Wired LAN connection on Ubuntu. While configuring any network resource we always need the IP Address to connect to the Domain/Network System. And this IP Address we configure either manually or using DHCP option(DHCP – the Dynamic Host Configuration Protocol – allows network devices to automatically obtain a valid IP address from a server.). There are many networking utilities we can use to configure the network, Now let see Network Interface configuration Using Command-Line.
Step 1: Go to Terminal and Type the below command.
gksudo gedit /etc/network/interfaces (if you have GUI)
sudo vi /etc/network/interfaces (use vi if no GUI installed)
-> Change to set if using DHCP
iface eth0 inet manually
iface eth0 inet dhcp
-> Change to set if using Static IP
iface eth0 inet static
Step 3: Save the file.
Step 4: After you save the file, Its time to restart networking services.
sudo /etc/init.d/networking restart
Now go to Administration -> System Monitor and click on the Resources Tab and observe the Network History to see the Network connection graph.
Yepeee.. you are now connected 🙂
One good thing I liked most about Windows 7 is the Desktop Gadget Feature, Very small widgets displaying different contents like weather information, clocks etc etc. I was searching for the same thing in Ubuntu and found a term called “Screenlets”, These are small programs that ﬂoat on the desktop and provide speciﬁc but useful functionality, such as telling the time, displaying a calendar, or showing the weather same like as I described for Windows 7 Gadgets.
To install the same follow the below steps.
1. Choose System Menu -> select Administration -> Synaptic Package Manager.
2. Package Manager dialog box, search for the keyword “screenlets“, this will bring down the packages “Screenlet, Screenlet-docs”,
3. Check the “Screenlets” and click on “Mark For Installation”
4. Now click on Apply button to download and install the packages.
5. Once installation finish. Quit the Package Manager.
6. Go to Application Menu -> Accessories -> Screenlets
7. Screenlets dialog will appear with all the gadgets..oops screenlet. Click on the clock screenlet and on the left side click on “Launch/Add“.
Now Screenlets are ready to decorate your desktop. ENjoy!!! UBUNTU.
In this post I will show how to set up an ADSL connection.You need to have to an Internet Service Provider, and your Internet connection must be installed and functional. You will need to configure your username and password for the connection. You must also have an ethernet card connected to your PPPoE modem with the correct type of cable.
And before going further make sure you have the PPPoE package installed in your ubuntu version. This package is installed by default, but can be missing if the configuration has been changed.
If missing login as root admin: open terminal type apt-get install pppoeconf
Now lets see how to setup a modem.
Open Applications → Accessories → Terminal
In the terminal type: sudo pppoeconf
A text-based menu program will guide you through the next steps, which are:
1. Confirm that your Ethernet card is detected.
2. Enter your username.
3. Enter your password.
4. If you already have a PPPoE Connection configured, you will be asked if it may be modified.
5. Popular options: you are asked if you want the “noauth” and “defaultroute” options and to remove “nodetach” – choose Yes.
6. Choose Yes for Use peer DNS –
7. Choose Yes for Limited MSS problem.
8. Choose Yes for When you are asked if you want to connect at start up.
9. Finally you are asked if you want to establish the connection immediately.
4. Once done, your connection should be working.
To start your ADSL connection on demand, in a terminal type: sudo pon dsl-provider
To stop your ADSL connection, in a terminal type: sudo poff dsl-provider
PS: Make sure to configure the basic firewall(Firestarter very popular), as it is recommended to protect the system from vulnerable attacks.
