Quick Opera install in Linux

In my opinion Opera is a very light weight, no-nonsense software. While opinions may vary, here is a easy way to install Opera in your Ubuntu/ Debian system.

Open to edit the apt sources.list file

sudo nano /etc/apt/sources.list

add the opera repo in a new line

deb http://deb.opera.com/opera/ stable non-free

Add the Opera GPG key with the command (recommended)

wget -O - http://deb.opera.com/archive.key | sudo apt-key add -

If you get authentication warnings, you may try (optional)

sudo apt-get install debian-archive-keyring

Run aptitude update

sudo apt-get update

Finally install Opera browser

sudo apt-get install opera

How to Set a Static IP in Linux Ubuntu Debian

We may require to configute a static IP address in our linux system. It is the easiest if you arterunning Ubuntu / debian distro.

Open up terminal and edit the 'interfaces' file in sudo mode

sudo nano /etc/network/interfaces

You would see the following lines

auto lo
iface lo inet loopback

replace the contents with the following:

auto lo eth0
iface lo inet loopback

iface eth0 inet static
address xxx.xxx.xxx.xxx(your static ip address)
netmask xxx.xxx.xxx.xxx(your network netmask)
gateway xxx.xxx.xxx.xxx(the gateway ip)

Save the file (Ctrl+O) and exit (Ctrl+X)

The ethusually the default network adapter. In a few cases it may be eth1.

I usually also change the nameservers to OpenDNS nameservers

sudo nano /etc/resolv.conf

replacing the contents with:

nameserver 208.67.222.222
nameserver 208.67.220.220

After that it is time to restart networking

sudo /etc/init.d/networking restart

Reboot your PC and check the ip with the command

ifconfig
