Webmin can be used to graphically for Linux system administration work. You can find more about Webmin in my previous post on webmin here.

Webmin is available free of cost and you can simply download from its site and is licensed under GPL. For Redhat/CentOS/Fedora you can download it in either rpm or tar.gz package. Now to install Webmin just follow the steps given below.

Installing WEBMIN:-
Step by Step Guide

• Firstly login as the root user or atleast you should have root privilege(sudo).
• Download the latest version of webmin from http://www.webmin.com/download.html and save it on the desktop.
• Now if you have downloaded .tar.gz version you need to extract the original file using gunzip and if you have downloaded the rpm version that just use the following command

# cd /root/Desktop

# rpm -ivh webmin-1.510.noarch.rpm

Linux distros are usually shipped with large number of software in the form of packages by which a system administrator can take a good care of the server running Linux. But these are generally command line utilities in which you need to manually edit the configuration files and manage the server.

Now if you are using Linux for personal computing or even in enterprise environment webmin can help you easily manage your server and that too graphically. Webmin runs graphically inside the web-browser and allows you to perform various functions such as apply quota, configure servers, manage file system, manage users and groups, schedule jobs, take back-ups and now it supports cloud computing as well.

Webmin has been more than 10years in market as of now and it is distributed under the general public license which allows an organization to modify it according to its needs.  Once installed you can log into webmin using your root username and password.

Samba is a service more specifically a protocol that enables the file and printer sharing between different operating system under the network. Unlike the NFS you can set registered users and permissions on the files available for sharing. Similarly you can share the printers in a LAN Environment using the samba server which is shipped along with all the major Linux distributions.  Samba Server can be integrated with a Windows Server domain, either as a Primary Domain Controller (PDC) or as a domain member. It can also be part of an Active Directory domain.

You need to configure a samba server and once configured you can simply drag and drop the files, view server contents and directories using windows file manager and can even edit the files available on the server. The name Samba comes from SMB (Server Message Block), the name of the standard protocol used by the Microsoft Windows network file system.

If you using Redhat Enterprise Linux on a vmware console than you can change the resolution of the console running Linux according to your need by simply editing the configuration file  xorg.conf . You can find more about Vmware in my previous post here. Installing Rhel5 on Vmware here.

Although when you run the vmware-tools script it makes all the necessary changes for you. But if you need to change the screen resolution to more than “800×600″ , you need to do it manually by editing the configuration file. To change the resolution simply follow the steps:

• open the configuration file /etc/X11/xorg.conf mode and make sure you have included 1024 x 768 mode as shown below

——————————————
Section “Screen”

Identifier “Screen0″

Device “Videocard0″

Monitor “Monitor0″

DefaultDepth 24

SubSection “Display”

Viewport 0 0

Depth 24

Modes “1024×768″

EndSubSection

——————————————

# vi /etc/X11/xorg.conf

You should have configuration file now as shown in above screenshot. Than save it and exit.

• You need to restart the X server. To do this simply press Ctrl+Alt+Backspace or log out and login in again.

• Now you can change the resolution of screen by simply switching to full screen mode.
