just now start installing centos 6.2 and ubuntu 13.04 and federo 19 ,installed facing issue in connecting to network , i dont know where to give the ip ,in order to learn i have installed in command line mode with the help of videos in youtube


Thanks in advance

Every Distros now have graphical tools to input such basics. What kind of network are you using???
In the gnome panel in the top right corner you will find some small icons, and one among them is for networking. You can enter the addresses in there. For command-line try using pppoe-setup.
All depends in what kind of network you are using.

the first thing is to upgrade cent
CentOS 6.2 is 3 minor versions and 2 years out of date

the current and ONLY supported version of 6 is CentOS 6.5

should do it


cent6.5 like RHEL 6.5 is a rather manual operating system

if you installed the default desktop Gnome2 there is a GUI tool for the netwark

you also might want to READ the Redhat Documentation
Cent uses the redhat docs
https://access.redhat.com/site/docum...erprise_Linux/

as to fedora 19

you might want to install the current Fedora 20
and have a look at the fedora docs
http://docs.fedoraproject.org/en-US/index.html
and
http://docs.fedoraproject.org/en-US/...ide/index.html

for Ubuntu

that is a Debian based distro
and DOSE NOT !!! use the same type of set up as Fedora and Cent

fedora and cent are RPM distros and use .rpm's
Ubuntu uses DEB destro and uses .deb files

think of it as
English VS. metric
Ford VS. GM
USA VS. CCCP
Redhat VS. Debian

In addition to having different package formats, CentOS, Fedora, and Ubuntu do a number of things differently as regards how to manage services and configuration routines and the like. CentOS uses System V for startup; Ubuntu uses its own thing called Upstart; Fedora uses System D.

They are all three Linux, but how they arrange information in the /etc directory, the details of where startup and configuration information is stored, and the command line tools they provide for inputting and altering configuration information differ.

I suggest you pick one distro, use it until you are comfortable with a basic knowledge of Linux, then branch out to others. It's probably a good idea to have a GUI available, even if you intend to learn how to do things from the command line; you could use the browser to look for information if you get stuck on something, for example.

You find a lot of useful references at The Linux Documentation Project.

A good site (also available as a downloadable .pdf and in print) for learning command line use:
