Configure Static IP Address on Linux

It is possible to configure a Linux network interface in multiple ways.

This is the one that might be simpler for beginners.

sudo ifconfig eth0 netmask;
sudo route add default gw eth0;

ifconfig is an application that allows to configure a network interface.

In the above example sudo is the command that allows us to elevate the user privileges to configure the network interface.

eth0 is the available interface, the list of available interfaces can be listed using the command ifconfig. is an example of a IP address it can be what you require to configure your network.

netmask identifies the subnet mask for the network that you are configuring. If you not sure what should be check the configuration settings of your router.

the second configuration line is the configuration of the default gateway. To achieve efficiency in getting out of the local network it is required to provide that information to the computer.

The gateway setting is the exit point of the local network to other networks. Route add is the command that it is used to add the route.

Default identifies that this is a default route. If no other route is inserted in the routing table the computer will use this route to speak with the remaining networks.

The address is the ip address of the gateway normally the address of the router in a local network.

The eth0 is the local interface that will be used to reach the gateway.

Microsoft Visual Studio, OSX and Linux

Microsoft has released a light version of Visual Studio for Linux and Mac OS X, there is also a version for Windows but that does not count…

What is interesting on this?

Well for start it seems that finally Microsoft considers the other OS systems important and the company might think to continue leading by incorporating their framework. (.net) into other Operating Systems.

The app seems more a first version of a trojan horse for OS X and Linux users to persuade them to install mono framework (.net).

Why I say this?
Because they advertise some interesting functionalities but apparently they only work if you install the mono framework.
Without the mono framework the tool is not much different from Text mate.

I am happy that Microsoft is trying to expand the .net framework to other platforms.

I had my first experience with mono in 2005 on earlier versions of .net and it was really useful. We used it to port some code into Linux but it was still immature back then, managed by enthusiasts without no real support from Microsoft.

Now with the .net foundation  and their projects things are starting to become more interesting, it is always good when we have competitors at same level JAVA and .NET… (now my Java friends and coworkers will stop talking with me because I used the words “same level” with java and .net…)

Java will have a huge headache in near future as .net starts spreading into Linux/Unix world.

Also it will be a huge advantage for the cloud when we have a major player like Microsoft Azure and we can start developing apps and tools using Linux instead of being exclusively obligated to have windows for a more efficient development.

According to the Microsoft Objectives .net apps will work in mobile phones, windows, Linux, MAC, etc. We can truly have the code once and use it everywhere…. 🙂

I am still waiting for Visual Studio 2015 for MAC… 🙂 that would be great…

Activar um interface no linux

Para inicializar um interface especifico no linux apenas temos de escrever o seguinte comando:

ifup eth0

Podemos substituir o eth0 pelo interface que pretendemos inicializar.
Atenção que temos de garantir que ele existe na lista de interfaces configurada no nosso sistema.
