Ubuntu Server:Install GUI and Webmin in Ubuntu 8.10 (Intrepid Ibex) Guide

1) Install desktop Environment

First you nee to make sure you have enabled Universe and multiverse repositories in /etc/apt/sources.list file once you have enable you need to use the following command to install GUI

sudo apt-get update

sudo apt-get install ubuntu-desktop

The above command will install GNOME desktop if you want to install KDE desktop use the following command

sudo apt-get install kubuntu-desktop

2) Install Webmin

Webmin is a web-based interface for system administration for Unix. Using any modern web browser, you can setup user accounts, Apache, DNS, file sharing and much more. Webmin removes the need to manually edit Unix configuration files like /etc/passwd, and lets you manage a system from the console or remotely.Currently There is no Webmin package in the Ubuntu repositories.This tutorial will explain how to Install Webmin in Ubuntu Intrepid Ibex

You can install webmin for your server web interface to configure apache2,mysql,FTp servers and many more.Now we will see how to install webmin in Ubuntu 8.10

Preparing your system

First you need to install the following packages

sudo aptitude install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl

Now download the latest webmin using the following command or from here

wget http://garr.dl.sourceforge.net/sourceforge/webadmin/webmin_1.441_all.deb

Now we have webmin_1.441_all.deb package install this package using the following command

sudo dpkg -i webmin_1.441_all.deb

This will complete the installation.

Ubuntu in particular don’t allow logins by the root user by default. However, the user created at system installation time can use sudo to switch to root. Webmin will allow any user who has this sudo capability to login with full root privileges.

Now you need to open your web browser and enter the following

Setting NTP Server On Fedora Core 6

NTP or network time protocol is a protocol that will synchronize the time of a computer client or server to another server or reference time source, such as a radio or satellite receiver or modem. Typical NTP configurations utilize multiple redundant servers and diverse network paths in order to achieve high accuracy and reliability.
Follow the below setup to install your ntp server:

1. install ntp: $ yum install -y ntp

2. edit ntp.conf: $ vi /etc/ntp.conf
example of ntp.conf:
# Permit time synchronization with our time source, but do not
# permit the source to query or modify the service on this system.
restrict default kod nomodify notrap nopeer noquery
restrict -6 default kod nomodify notrap nopeer noquery

# Permit all access over the loopback interface. This could
# be tightened as well, but to do so would effect some of
# the administrative functions.
restrict 127.0.0.1
restrict -6 ::1

# Hosts on local network are less restricted.
#restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap

# Use public servers from the pool.ntp.org project.
# Please consider joining the pool (http://www.pool.ntp.org/join.html).
#server 0.rhel.pool.ntp.org
#server 1.rhel.pool.ntp.org
#server 2.rhel.pool.ntp.org
#server mst.sirim.my prefer
#server my.pool.ntp.org

#broadcast 192.168.1.255 key 42 # broadcast server
#broadcastclient # broadcast client
#broadcast 224.0.1.1 key 42 # multicast server
#multicastclient 224.0.1.1 # multicast client
#manycastserver 239.255.254.254 # manycast server
#manycastclient 239.255.254.254 key 42 # manycast client

# Undisciplined Local Clock. This is a fake driver intended for backup
# and when no outside source of synchronized time is available.
#server mst.sirim.my prefer
#server my.pool.ntp.org

# Drift file. Put this in a directory which the daemon can write to.
# No symbolic links allowed, either, since the daemon updates the file
# by creating a temporary in the same directory and then rename()'ing
# it to the file.
driftfile /var/lib/ntp/drift

# Key file containing the keys and key identifiers used when operating
# with symmetric key cryptography.
keys /etc/ntp/keys

# Specify the key identifiers which are trusted.
#trustedkey 4 8 42

# Specify the key identifier to use with the ntpdc utility.
#requestkey 8

# Specify the key identifier to use with the ntpq utility.
#controlkey 8

3. If the server you are setting up do not have internet connection, you can synchronize it with the local time of the server itself. Just comment the server part, and change it to 127.127.1.0. The sratum level is for determining what level this time server is set up for. Stratum 0 usually refers to real clock, for example atomic (cesium, rubidium) clocks or GPS clocks or other radio clocks. Stratum 1 is the machine connected to stratum 0 devices.

#server mst.sirim.my prefer
#server my.pool.ntp.org
server 127.127.1.0
fudge 127.127.1.0 stratum 10

4. synchronize the server's time with the ntp server: $ ntpdate -du mst.sirim.my

5. start ntp service: $ /etc/init.d/ntpd start

In the client machine, just type: $ ntpdate -du ntpservername. You can also put this command in crontab for the client to be update frequently
