Linux Networking

Internet Protocol

Untuk terhubung pada suatu jaringan diperlukan penomoran dari Internet Protocol yang ada pada PC tersebut. Teknik penomoran IP ada 2 yaitu manual dan otomatis (DHCP). Pada suatu jaringan diperlukan IP dan netmask, contoh:

192.168.0.1/255.255.255.0

192.168.0.1 adalah penomoran IP, sedangkan 255.255.255.0 adalah netmask dari jaringan tersebut. IP memiliki beberapa class yang terbagi menurut jumlah IP tersebut. Class yang ada antara lain:

A. 10.x.x.x dengan netmask 255.0.0.0

B. 172.16.x.x s/d 172.31.x.x dengan netmask 255.255.0.0

C. 192.168.0.x s/d 192.168.255.x dengan netmask 255.255.255.0

D dan E tidak digunakan, karena diperuntukan untuk penelitian

Penomoran netmask dapat disingkat, misalkan 255.255.255.0 dapat disingkat menjadi /24

Setting IP di Linux

a. Perintah “ifconfig”

Dengan menggunakan perintah ifconfig, root dapat mengganti setting IP untuk jaringan.

Contoh :

highway:~# ifconfig

eth0 Link encap:Ethernet HWaddr 00:0C:F1:BA:38:43

inet addr:10.252.102.143 Bcast:10.252.102.255

Mask:255.255.255.0

inet6 addr: fe80::20c:f1ff:feba:3843/64 Scope:Link

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1

RX packets:7827318 errors:0 dropped:0 overruns:0 frame:0

TX packets:5486496 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:1000

RX bytes:2529035045 (2.3 GiB) TX bytes:1421757215 (1.3 GiB)

lo Link encap:Local Loopback

inet addr:127.0.0.1 Mask:255.0.0.0

inet6 addr: ::1/128 Scope:Host

UP LOOPBACK RUNNING MTU:16436 Metric:1

RX packets:999 errors:0 dropped:0 overruns:0 frame:0 TX packets:999 errors:0 dropped:0 overruns:0 carrier:0

collisions:0 txqueuelen:0

RX bytes:68831 (67.2 KiB) TX bytes:68831 (67.2 KiB)

Untuk mengganti IP dapat dilakukan dengan cara:

# ifconfig eth0 192.168.0.1 netmask 255.255.255.0

b. Dengan menyimpan konfigurasi jaringan

Pada Debian GNU/Linux, file konfigurasi jaringan terdapat pada /etc/network/interfaces,

dapat dilakukan dengan menggunakan editor vim, nano, atau mcedit.

# vim /etc/network/interfaces

pada file tersebut ketikkan syntax berikut:

auto lo

iface lo inet loopback

auto eth0

iface eth0 inet static

address 10.252.108.143

netmask 255.255.255.0

kemudian jalankan perintah “/etc/init.d/networking restart”

apabila ingin menggunakan DHCP ganti “iface eth0 inet static” menjadi “iface eth0 inet

dhcp”

IpRoute2 dan IPV6

IPRoute2
IPRoute2 adalah sekumpulah aplikasi yang digunakan untuk mengontrol Jaringan berbasis TCP/IP dan mengontrol aliran data (traffic control) di mesin Linux. Padaumumnya untuk mengontrol jaringan di linux menggunakan aplikasi ifconfig dan route.
Karena berbagai macam keterbatasan dan kurang efisien maka aplikasi yang digunakan beralih ke IPRoute2, walaupun sampai saat ini Linux masih mencantumkan aplikasi­aplikasi tersebut.
Installasi IPRoute2 dapat dilakukan dengan cara :

# apt-get install iproute

Untuk mengetahui “Link” (layer2) yang kita gunakan, dapat dilakukan dengan perintah :

pluto:/home/dhoto# ip link
1: lo: mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: eth0: mtu 1500 qdisc cbq qlen 1000

3: eth1: mtu 1500 qdisc cbq qlen 1000

4: sit0: mtu 1480 qdisc noop
link/sit 0.0.0.0 brd 0.0.0.0

Untuk melihat ip address mesin kita, dapat dilakukan dengan perintah:
pluto:/home/dhoto# ip address show
1: lo: mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

4: sit0: mtu 1480 qdisc noop
link/sit 0.0.0.0 brd 0.0.0.0

Untuk melihat table routing, dapat dilakukan dengan :

pluto:/home/dhoto# ip route show

202.154.187.7
10.252.101.0/24 dev eth1 proto kernel scope link src
10.252.101.1
default via 202.154.187.1 dev eth0


Untuk melihat ARP, dapat dilakukan dengan perintah :

pluto:/home/dhoto# ip neigh show

Internet Protocol version 6 (IPv6)

Ipv6 merupakan kelanjutan dari Ipv4 yang telah kita gunakan. Tujuan dari Ipv6 adalah untuk meningkatkan jumlah IP address. Dimana ipv4 menggunakan 32 bit, artinya jumlah ip address adalah 232 (sekitar 4 milliar), dan sekarang sudah mulai habis..
Ipv6 dapat dikonfigurasi secara stateless autoconfiguration, artinya host akan mengikuti IP yang diberikan oleh router dijaringan tersebut. Berbeda dengan DHCP yang bersifat statefull autoconfiguration. Notasi untuk ipv6, menggunakan 4 huruf hexadesimal (0­F) dan memiliki 8 group, dipisahkan dengan “:” (titik dua). IPv4 menggunakan bilangan desimal dari 0­255 dan terdiri dari 4 group. Apabila pada ipv6 terdapat bilangan 0000, maka dapat disingkat menjadi (::).

Contoh :
2001:0db8:0000:0000:0000:0000:1428:57ab
2001:0db8:0000:0000:0000::1428:57ab
2001:0db8:0:0:0:0:1428:57ab
2001:0db8:0:0::1428:57ab
2001:0db8::1428:57ab
2001:db8::1428:57ab

Pada ipv6 terdapat alamat khusus, yaitu:
– ::/128, artinya semua alamat adalah 0 dengan netmask 128
– ::1/128, alamat loopback– ::/96, alamat yang digunakan untuk ipv4
– 2001:db8::/32, alamat global dan yang digunakan untuk ipv6
– fe80::/64, alamat link­local
– ff00::/8, alamat multicast untuk ipv6

Configuring an Access Point as a Wireless Repeater (LinkSys)

The Linksys Wireless-G Access Points can be configured as an Access Point, Access Point Client, Wireless Repeater, and Wireless Bridge. The Wireless Repeater mode will turn the access point into a wireless repeater to extend the range of your signal.

The WAP54G will work as a wireless repeater with the following devices:

• Linksys Wireless-G Access Point (WAP54G)
• Linksys Wireless-G Router (WRT54G)

To configure the access point as a wireless repeater, you need to perform two steps:

1. Checking the Wireless MAC Address of a Wireless Router/Access Point
2. Setting-Up Wireless Repeater Mode on the WAP54G

Checking the Wireless MAC Address of a Wireless Router

To check the wireless MAC Address of the wireless router follow the steps below.

Step 1:
Access the router’s web-based setup page.

Step 2:
When the router’s web-based setup page opens, click Status then click Wireless.

Step 3:
Take note of the MAC Address. This is your router’s wireless MAC address.

NOTE: The Wireless MAC Address you took note of will be entered on the WAP54G set as wireless repeater. After checking the wireless MAC Address, set-up the wireless repeater mode on the WAP54G. To check the wireless MAC address of the access point, follow the steps below.

Checking the Wireless MAC Address of an Access Point

Step 1:
Connect a computer to the access point.

Step 2:
Assign a static IP address on the computer.

Step 3:
Open the access point’s web-based setup page.

Step 4:
When the access point’s web-based setup page opens, take note of the Wireless MAC Address.

NOTE: The Wireless MAC Address you took note of will be entered on the WAP54G set as wireless repeater.

Step 5:
After obtaining the wireless MAC address of the router/access point, configure the other WAP54G as a wireless repeater. For instructions, follow the steps below.

Setting-Up Wireless Repeater Mode on the WAP54G

Step 1:
Access the access point’s web-based setup page.

Step 2:
When the access point’s web-based setup page opens, click AP Mode then select Wireless Repeater.

NOTE: The access point’s web-based setup page may differ depending on the access point’s version number.

Step 3:
Type the wireless MAC address you took note of earlier in the Remote Access Point’s LAN MAC Address field.

NOTE: Remove the colons (:) when typing the MAC address on the Remote Access Point’s LAN MAC Address field.

Step 4:

Click .

NOTE: If you will connect the wireless repeater to another WAP54G, change the wireless repeater’s LAN IP address.

Membuat Router Statis dan Dinamis pada Packet Tracer

Persiapan :

Pastinya di komputer Anda sudah terinstall Software Packet Tracer. Kalau Anda belum punya softwarenya nih saya kasih link downloadnya. Klik disini untukl mendownload.

Setelah Anda download install deh software-nya
di komputer Anda. Setelah Anda install sekarang jalankan program packet tracernya. maka akan muncul seperti ini :







Untuk Membuat Router kita klik pada gambar icon Router. Disini saya menggunakan Router-PT (lingakaran merah)
dan membuat 3 router.






Setelah itu kita beri client (pc) pada setiap router dan kita sambungkan semuanya. Gunakan "automatically choose connection type" untuk menyambungkan setiap device.








Setelah selesai sekarang kita isikan IP pada setiap devicenya. Terserah Anda isi IP berapa. Disisni saya akan mengisi IP-nya seperti berikut :

Router 0
FastEthernet0/0 ==> 192.168.1.1
Serial2/0 ==> 112.16.1.1
Clock rate ==> 9600

Router 1
FastEthernet0/0 ==> 192.168.1.2
Serial2/0 ==> 112.16.1.2
Serial3/0 ==> 113.16.1.1
Clock rate ==> 9600

Router 2
FastEthernet0/0 ==> 192.168.1.3
Serial2/0 ==> 113.16.1.2
Clock rate ==> 9600


PC 0
Gateway ==> 192.168.1.1
