Connecting a GSM network in ubuntu, no problem! Follow the following steps :

2. Select tab 'Mobile Broadband'.



3. Click on add, a wizard opens for New Mobile Broadband Connection.


 
4. You would be prompt to select Country, Service Provider and plan.


5. On completion of the wizard, a new window would open, leave it as it is.


6. You may change the settings ( also known as dial-up settings ) in window above.
7. And yes, don't forget to check Available to all users. Enter password when prompted.


 8. Select network applet, select your newly created connection.

Configuring network manually on Linux

Sometimes, it may happen that our Linux OS does not detect the Internet connection despite connectivity [ It generally happens in Proxy servers ]

Open terminal and type

decapsulatingabstraction@ubuntu:~$ sudo -s 
[sudo] password for decapsulatingabstraction:
root@ubuntu:~# ifconfig eth0 your IP netmask your subnet mask
root@ubuntu:~# route add default gateway IP v4/v6 Gateway
root@ubuntu:~# sh -c "echo nameserver IP v4 DNS > /etc/resolv.conf"

 You can view your network configuration using ifconfig


If you hate terminal then also there's a way out, here it is:

1. Click on the network applet, select edit connections




2.  Select a pre-existing connection or simply add a new, then click on edit,


3. Give a connection name, add Auto in front of it, if you want that connection to be connected automatically.

4. In IPv4 tab, make the method manual.


5. After making the method Manual, click on add, and edit the present addresses to desired ones



5. Save it !


For NIT Durgapur students, 


IPv4 Gateway 172.16.40.1
IPv4 DNS        172.16.1.90
Subnet Mask   255.255.254.0


for Manual DHCP,  DHCP = 172.16.1.90

Enjoy Networking !!!

kumar-pravin: a father figure

I first met this man regarding conf.kde.in, sometime in February, and together we had gone there, it was a great experience spending some quality time with the real 'techies' of industry and the foss guys. The whole of journey was exciting, informative and refreshing.

Some snaps and conference details:

It was attended by me Praveen Ravi Mukul Sam Vikas Tirtha

Overall we found Pravin as a father figure to us, it he restrained us from doing any bad, except the k-hut project which he accepted to be a packager. Praveen was the strictest of all, had Ravi not been there, Praveen would have made our days .... He is a man whom I would never like to forget, a nerdy geek, always having a reason for what he is doing and ice cool personality.

why 'decapsulating abstraction'

First of all there is no proper word called Decapsulating in English dictionary, These words originated in our Object Oriented Programming (OOPS!!!!) in our third semester.

Encapsulation : Process of enclosing data members and functions in a class (user defined data type)
Abstraction    :  Simply hiding a part of information content of a concept


hope you got it!!!!
