Modul 17 Server Administration on network

(5)

Server administration on network is a work form conducted by network administrator having duty to make server, managing tied on network is server, monitoring network, as well as protecting the transfer of data in network.

Explanation

(6)

Step by Step Conducted Administrator

 Chosening aplication for server,

 Chosening operating system for network,

 Chosening component for server,

 Specifying the specification of server,

 Develop and configuraton of server.

 Testing server,

 Monitoring network performance.

CHOSENING APLICATION FOR SERVER

Target Activity of Study.

1. Participant of diklat can determine application to be run server.

2. Participant of diklat can know application functions.

HOME

(9)

Application used by server to run network for example :

a. DNS b. DHCP c. FTP

d. Web Server e. Mail Server f. Samba

g. Proxy

CHOSENING OPERATION SYSTEM FOR NETWORK

HOME

(11)

Target Activity of Study

1. Participant of diklat can determine operating system server used.

2. Participant of diklat can chosen operating system for server.

HOME

(12)

Operating system which often used in a network is Microsoft Windows, Linux, Unix, dan Apple Macintosh.

(13)

But to be is this we will make a network of server use operating system of LINUX,

Why choosen operating system of linux ?

• Linux have the character of freeware / shareware,

• We don’t require license if installation of linux,

• We earn to determine application of we installation at server we which have make, etc.

(14)

CHOSENING COMPONENT FOR SERVER

(15)

Target Activity of Study

1. Participant of diklat can determine components to be server used.

2. Participant of diklat can know components functions.

HOME

(16)

If we make a server which incircuit with a network hence us need network appliance among others :

 NIC  HUB

 Switch

 Server Computer

(17)

 Cabel complete with conektor

1. Chopper  Coaxial, Twisted Pair (UTP, STP) 2. Fiber Optic

 CD operating system of server

(18)

SPECIFYING THE SPECIFICATION OF SERVER

SERVER ADMINISTRATION ON NETWORK

HOME

(19)

Target Activity of Study

1. Participant of diklat can determine the specification of computer server.

2. Participant of diklat can know minimum specification which required for network.

HOME

(20)

No. Name of Material Picture 1 Motherboard

2 Casing 3 Monitor

We will make server use red hat linux, hence minimal specification which we need is :

(21)

4 Mouse

5 Keyboard 6 Processor 7 Memory

8 Hard Disk Drive

(22)

9 CD-Rom

10 NIC

11 Cables and connectors

12 Hub 13 Switch

DEVELOP AND CONFIGURATION OF SERVER

SERVER ADMINISTRATION ON NETWORK

HOME

(24)

Target Activity of Study.

1. Participant of diklat can develop and configuraton of server.

2. Participant of diklat can do installation of operating system and application server.

HOME

(25)

After we finish to determine specification and component of server, step here in after to develop and configuraton of server.

But before developing and configuraton of server, we beforehand have to string up all component of server

specification and which have been prepared.

(26)

After all component have been connected, hence step here in after we have to its operating system installation that is linux red hat.

Do installation of linux red hat till finish and do

accurately so that its system don’t experience of damage or error.

(27)

A. DNS (Domain Name Server)

That is representing system in form of distribution database to map / converting the name of host / machine / domain to address of IP (Internet Protocol) conversely

from address of IP to name of host is so-called with

reverse-mapping, or is easier of DNS used to remember the name of than address of IP.

After installation of operating system of Red hat finish, hence step here in after is application installation required by server. Application we to install among others :

(28)

Address File

 named.conf on /etc

 named.ca on /var/named

 named.local on /var/named

If we like to make master of server hence there must be :

 file zone -> mapping from name to IP

 file reverse zone -> mapping from IP to name Files which need configuraton in DNS for example :

(29)

(Domain Name Server)

(30)

B. DHCP (Dynamic Host Configuration Protocol)

That is DHCP used to give IP at client automatically which possible some server walk in network, with note of range IP every server there may not be any which overlap.

Especialy Configuraton file of DHCP Server in etc/dhcp3/dhcpd.conf

Configuration example :

option domain-name "test1.com";

option domain-name-servers 192.0.0.1, 194.2.0.50;

option routers 192.0.0.151;

default-lease-time 3600;

subnet 192.0.0.0 netmask 255.255.255.0 { range 192.0.0.200 192.0.0.254;

}

C. FTP (File Transfer Protocol)

That is One of the provided by application server in network giving service in the form of delivery

an file to other PC or to PC client.

File configuraton of vsftpd.conf which in directory /etc/, eliminating sign # at some existing

script to be able to run server ftp.

FTP System working (File Transfer Protocol)

client server

(33)

D. Web Server

That is application provided by server to be client can access server in the form of page of html.

File configuraton of apache2.conf which in directory /etc / apache2/, change and searching some script to be able

to walk service of apache2.

ServerRoot  Root from apache2 Listen  Port http:// (usually 80)

DocumentRoot  Document location HTML Users  apache will be run as user and group ServerName  assign Name server

ServerAdmin  email address admin DirectoryIndex  file default to be run

(34)

Web server System Working

(35)

E. Mail Server

That is application provided by server to be client can communicate with server and or between client in the form of containing electrical letter of text and or animation.

How e-mail delivered?

• MUA = Mail User Agent, aka Mail Client

• MTA = Mail Transport Agent, aka Mail Server

MUA MUA

MTA

Sender Recipient

LAN

Internet LAN Internet

(36)

F. Samba

That is application used to connect server wearing operating system of Linux with computer of client

wearing operating system besides linux, like or windows of Apple Macintosh.

Install Packages of samba among others:

rpm –qa | grep samba

samba-2.2.7a-8.9.0

samba-swat-2.2.7a-8.9.0

samba-common-2.2.7a-8.9.0 samba-client-2.2.7a-8.9.0

(37)

After all package installation of samba finish, hence which need configuraton us :

#mv /etc/samba/smb.conf smb.org.conf

# vi /etc/samba/smb.conf

delete all existing article change article to following :

# ---

# Test smb.conf file

# mawi 2003-07-28

# --- [global]

workgroup = TESTSAMBA-GRP netbios name = TESTSAMBA security = SHARE

[test]

path = /tmp/test read only = no guest ok = yes

(38)

G. proxy

That is Proxy represent third party standing in the centre of among both side ( Server-Client) which interaction and function as medium.

File configuraton /etc/squid/squid.conf

http_port  determining squid will walk in port how many or will walk in Ip how many and port how many

Example :

– http_port 192.168.0.1:8080 (jalan di IP 192.168.0.1 di port 8080)

– http_port 8080 (jalan di sembarang IP di port 8080)

Target Activity of Study

1. Participant of diklat can test result of installation server.

2. Participant of diklat can connect server with computer clients

HOME

(42)

After all application installation finish and walk better hence step here in after we test result of application

settings.

Examination steps :

 Joint computer of server with switch with fiber optic cable

 Joint computer of clients with switch with UTP cable

 Test connection among server with client

 Test client all provided by application server through computer of client.

(45)

Target Activity of Study

1. Participant of diklat can monitor network performance which have been made.

2. Participant of diklat can use application to be used to monitor network.

HOME

(46)

We earn to monitor network performance use a application, like application. CNC / NAGIOS AND CACTI NETWORK MANAGEMENT AND MONITORING SYSTEMS.

(47)

Problem & Duty

Question

1. What have to be done first time in Administration of Server in network ?

2. Any kind of performed within administration of server in network ?

Duty

1. Make administration of server use different operating system as well as aplkasi to be used to monitor
