Belajar Linux.. Linux Networking Tools

Sabtu, 23 April 2011

 

Linux Networking Tools
Untuk menunjang kelancaran jaringan diperlukan linux networking tools, sehingga pengguna dapat melihat status jaringannya dengan bantuan beberapa perangkat lunak.
Untuk itu kita membutukan:
  1. Satu buah PC dengan system operasi Linux
  2. Siapkan kabel LAN, Switch.
    Caranya dapat Anda ikuti proses dibawah ini:

  1. Lepaskan kabel lakukan perintah mii-tool
Perintah mii-tool berfungsi untuk mengecek link sudah terhubung atau belum. Mii-tool (Media Independent Interface).
  1. Pasang kabel dan lakukan perintah mii-tool
Apabila sudah keluar eth0 artinya perangkat jaringan kita menggunakan eth0. 100base-TX-FD artinya kita menggunakan kecepatan 100Mbps dan FD adalah Full-Duplex. dan Link ok menandakan perangkat kita sudah siap. Apabila hasilnya bukan link ok artinya ada masalah dengan perangkat kita.
  1. Catat hasil perintah diatas menggunakan perintah #lspci
Apabila ditemukan Network controller atau Ethernet controller, artinya perangkat jaringan sudah siap digunakan.
4.      Rubah IP sesuai dengan DHCP. Jalankan 2 buah konsole (terminal), dimana terminal pertama melakukan ping terhadap alamat broadcast, sedangkan terminal yang satu lagi mencatat jenis koneksi dengan perintah “arp” .
root@lab3-laptop22:/home/lab3# gedit /etc/network/interfaces
gedit1.png
Simpan file diatas, Lalu restart dengan perintah dibawah ini:

root@lab3-laptop22:/home/lab3# /etc/init.d/networking restart

There is already a pid file /var/run/dhclient.eth0.pid with pid 2900

Coba ping alamat broadcast yang tertampil pada ifconfig, caranya ketik perintah ping –b <alamat broadcast> :
root@lab3-laptop22:/home/lab3# ping -b 172.22.22.255

Ini hasilnya jika Anda ketik perintah arp:

  1. Ganti IP PC menjadi 192.168.0.*/24, kemudian catat hasil dari perintah “ifconfig” dan “route”.
Pada praktek kali ini saya menggunakan IP Address 192.168.0.15
Coba ubah IP menggunakan perintah dibawah ini:
root@lab3-laptop22:/home/lab3# ifconfig eth0 192.168.0.15 netmask 255.255.255.0
Lalu catat hasil pada dari perintah ifconfig dibawah ini:
root@lab3-laptop22:/home/lab3# ifconfig

Catat hasil pengubahan IP menggunakan perintah route:
root@lab3-laptop22:/home/lab3# route

Kernel IP routing table

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

192.168.1.0     *               255.255.255.0   U     2      0        0 wlan0

192.168.0.0    *               255.255.255.0   U     0      0        0 eth0


6.      Ganti IP PC menjadi DHCP, kemudian catat hasil dari perintah “ifconfig” dan “route”
Untuk mengubah IP PC menjadi DHCP Anda dapat langsung melakukan perintah restart atau mengubahnya pada /etc/network/interfaces.
 Pada praktek ini langsung menggunakan perintah restart seperti dibawah ini:
root@lab3-laptop22:/home/lab3# /etc/init.d/networking restart

 * Reconfiguring network interfaces...                                                                          RTNETLINK answers: No such process

There is already a pid file /var/run/dhclient.eth0.pid with pid 3288

7.      Pastikan PC menggunakan IP DHCP, kemudian catat hasil dari ping, traceroute dan mtr pada target berikut
1. 10.252.13.90
2. 202.154.187.7
3. www.eepis-its.edu
4. www.yahoo.com

root@lab3-laptop22:/home/lab3# ping 10.252.13.90

PING 10.252.13.90 (10.252.13.90) 56(84) bytes of data.
Target diatas tidak berhasil di Ping karena tidak ada koneksi ke internet.

8.      Catat kondisi PC dengan perintah “netstat -nlptu”

9.      Buka halaman http://www.eepis-its.edu dengan web browser, kemudian sebelum koneksi selesai, buka terminal dan catat hasil koneksi dengan perintah “netstat -natu”

root@lab3-laptop22:/home/lab3# netstat -natu
