LINUX NETWORKING TOOLS
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:
- Satu buah PC dengan system operasi Linux
- Siapkan kabel LAN, Switch.
Caranya dapat Anda ikuti proses dibawah ini:
- Lepaskan kabel lakukan perintah mii-tool
Perintah mii-tool berfungsi untuk mengecek link sudah terhubung atau belum. Mii-tool (Media Independent Interface).
- 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.
- 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
Simpan file diatas, Lalu restart dengan perintah 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 2900
killed old client process, removed PID file

Ini hasilnya jika Anda ketik perintah arp:

192.168.1.1 ether 00:18:f8:4a:4d:49 C wlan0
- 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:

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

192.168.0.0 * 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

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”
root@lab3-laptop22:/home/lab3# 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
Active Internet connections (servers and established)
