The following Blog is a short summary on Redhat and ubuntu and some differences between them, we have also provided a some commands and file names on how to configure network in RedHat PCs and in Ubuntu PCs, so you could understand that configuring network in both of them is different.

Red Hat Enterprise Linux is not free, and its also used for business.Red Hat Linux, assembled by the company Red Hat, was a popular Linux based operating system.
Red Hat Linux 1.0 was released on November 3, 1994. It was originally called “Red Hat Commercial Linux”[2] It is the first Linux distribution to use the packaging system, the RPM Package Manager as its packaging format, and over time has served as the starting point for several other distributions, such as Mandriva Linux and Yellow Dog Linux.
Red Hat’s Features:
Red Hat Linux introduced a graphical installer called Anaconda, intended to be easy to use for novices, and which has since been adopted by some other Linux distributions. It also introduced a built-in tool called Lokkit for configuring the firewall capabilities.

It uses .rpm package called Red Hat Package Manager.

Definition rpm: The RPM Package Manager (RPM) is a powerful command linedriven package management system capable of installing, uninstalling, verifying, querying, and updating software packages. Each software package consists of an archive of files along with information about the package like its version, a description, etc.

Now What is yum? yum, also called Yellow dog Updater Modified, is a Linux utility which is use to install RPM packages/Binary Files (.rpm files). You can use yum with the following options.

Installing packages(.rpm):- To install any .rpm packages follow these command.

# yum install packagename

  # rpm -ivh packagename.rpm

Networking

etworking Files are that files by which system get connected in the Network.

By editing these files system will be get connected in Network.

 To set IP Address

# system-config-network

  or in the below file:

# cat /etc/sysconfig/network-scipts/ifcfg-eth0

To set gateway

# system-config-network

or in the below file:

# cat /etc/sysconfig/network

To set DNS

 #cat /etc/resolv.conf

To set hostname

# hostname yourcomputerName

# cat /etc/sysconfig/network

Booting Files

# cat /boot/grub/grub.confAbout grub.conf :- Grub Conf is a Gnome2 based GRUB configuration editor. It provides an easy to use interface allowing effortless modification of OS’s and the flexibility to configure the most obscure options. Designed to require minimal user interaction while providing tools for the most adventurous user.

To see the version of Operating System:

# cat /etc/redhat-release

To on services permanently:

# chkconfig servicename on

                                                                 Ubuntu Ubuntu is an operating system, like windows.Ubuntu is a Linux distribution that starts with the breadth of Debian and adds regular releases (every six months), a clear focus on the user and usability (it should “Just Work”, TM) and a commitment to security updates with 18 months of support for every release. Ubuntu ships with the latest Gnome release as well as a selection of server and desktop software that makes for a comfortable desktop experience off a single installation CD.

Ubuntu uses the.deb apt package:- Ubuntu uses .deb package for package installation as like .rpm of Red Hat.

Ubuntu also uses apt-get package installer to install packages by using command mode.
To install package Graphically, synaptic package manager.

Installing Packages (.deb)

# apt-get install packagename

# dpkg -i packagename.deb

To install packages Graphically by synaptic:

System -> Administrator -> Synaptic Package Manager

Networking

Some files to get connected system in Network.To set IP Address & Gatway

# cat /etc/network/interfaces

To set DNS

# cat /etc/resolv.conf

To set hostname

# cat /etc/hostname

Package Management

Ubuntu has more packages available than Fedora, so you’ll have a better chance of finding what you want in the repositories. As with Fedora, graphical applications will put a link into the Applications menu.

Graphical Tools

The Synaptic package Manager is an excellent tool for finding, fetching and installing packages. Press System -> Administration -> Synaptic Package Manager to start Synaptic.

Command Line Tools

Ubuntu uses apt-get instead of yum, up2date and so on to find, download, and install packages and their dependencies.

Note that, unlike yum, apt-get is only for packages available in repositories – it cannot handle packages you have already downloaded. The dpkg command is used instead.

Table of Equivalent Commands

Below is a table of equivalent commands for package management on both Ubuntu/Debian and Red Hat/Fedora systems.

Services

Services on Ubuntu are managed in a broadly similar way to those on Red Hat.

Graphical Tools

Services can be configured by clicking System -> Administration -> Services. A tool called Boot-Up Manager is also available.

Command Line Tools

Below is a table of example commands for managing services. The apache/httpd service is used as an example.

Task Red Hat / Fedora Ubuntu Ubuntu
(with sysv-rc-conf or sysvconfig)
Starting/stopping services immediately service httpd start invoke-rc.d apache start service apache start
Enabling a service at boot chkconfig httpd on update-rc.d apache defaults sysv-rc-conf apache on
Disabling a service at boot chkconfig httpd off update-rc.d apache purge sysv-rc-conf apache off

Note: Whereas Red Hat and Fedora servers boot into runlevel 3 by default, Ubuntu servers default to runlevel 2.

Note: The service and invoke-rc.d commands call init scripts to do the actual work. You can also start and stop services by doing e.g. /etc/init.d/apache start on Ubuntu, or /etc/init.d/httpd start on Red Hat/Fedora.

Network

Graphical Tools

Fedora/RHEL have system-config-network, ubuntu pre 10.04 had gnome-nettool to edit static ip address, since 10.04 nm-connection-editor is the best choice. For Ubuntu 10.04 Studio there is only manual editing of files since NetworkMontor is not included
