the biggest cause of network outages is not hardware or software failures, it’s folks making configuration changes.

Indeed Sir!

atl2 adalah modul (driver) kernel untuk chipset ethernet Attansic (kemudian dibeli atheros) tipe L2, yang banyak digunakan oleh motherboard ASUS keluaran baru
Cirinya memiliki PCI id sebagai berikut:
02:00.0 Ethernet controller: Unknown device 1969:2048 (rev a0)
Agar dapat dikenali dan digunakan oleh Debian, pada sistem perlu ditambahkan modul atl2. Modul ini secara default belum disertakan pada instalasi Debian Etch, namun sejak Debian4.0r4 (etch-n-a-half), Debian sudah menyertakan paket source atl2 dan kernel 2.6.24 pada repositorinya sehingga memudahkan kita untuk melakukan instalasi .

Langkah-langkah Instalasi

1. Cek /etc/apt/sources.list yang anda pakai, Pastikan mengarah pada mirror Debian yang lengkap, kalau tidak yakin dengan mirror yang saat ini anda pakai, gunakan :
   http://kambing.vlsm.org/debian etch main non-free contrib
   
2. Jalankan aptitude update untuk memperbarui catatan daftar paket mirror di sistem sesuai kondisi terkini.
   
   Cek apakah repo yang digunakan sudah memiliki paket etchnhalf:
   
cn-anjas:~# aptitude search etchnhalf
p linux-headers-2.6-486-etchnhalf - Header files for Linux 2.6-etchnhalf on x8
p linux-headers-2.6-686-bigmem-et - Header files for Linux 2.6-etchnhalf on PP
p linux-headers-2.6-686-etchnhalf - Header files for Linux 2.6-etchnhalf on PP
p linux-headers-2.6-amd64-etchnha - Header files for Linux 2.6-etchnhalf on AM
v linux-headers-2.6-etchnhalf -
p linux-headers-2.6.24-etchnhalf. - Header files for Linux 2.6.24 on x86
p linux-headers-2.6.24-etchnhalf. - Header files for Linux 2.6.24 on PPro/Cele
p linux-headers-2.6.24-etchnhalf. - Header files for Linux 2.6.24 on PPro/Cele
p linux-headers-2.6.24-etchnhalf. - All header files for Linux 2.6.24
p linux-headers-2.6.24-etchnhalf. - All header files for Linux 2.6.24
p linux-headers-2.6.24-etchnhalf. - Header files for Linux 2.6.24 on AMD64
p linux-headers-2.6.24-etchnhalf. - Common header files for Linux 2.6.24
p linux-image-2.6-486-etchnhalf - Linux 2.6-etchnhalf image on x86
...
(disingkat)

   
   
3. Install paket kernel image, kernel header, compiler, dan debian packaging tools:
   cn-anjas:~# aptitude install linux-image-2.6.24-etchnhalf.1-686 \
linux-headers-2.6.24-etchnhalf.1-686 build-essentials kernel-package \
debhelper module-assistant
   
   
4. Reboot sistem agar kernel yang baru diinstalasi aktif
   
5. Download paket source modul atl2 ( atl2-source-etchnhalf*.deb) dari
   http://kambing.vlsm.org/debian/pool/main/a/atl2-etchnhalf/
   Kemudian install paket tersebut:
   cn-anjas:~# dpkg -i atl2-source-etchnhalf_2.0.3-3~etchnhalf.1_all.deb
   source code modul atl2 akan diinstalasi ke direktori /usr/src/etchnhalf/
   
6. Ekstrak source atl2.tar.bz2
   
cn-anjas:~# cd /usr/src/etchnhalf/
cn-anjas:/usr/src/etchnhalf# ls
atl2.tar.bz2
cn-anjas:/usr/src/etchnhalf# tar xf atl2.tar.bz2
cn-anjas:/usr/src/etchnhalf# ls
cn-anjas:/usr/src/etchnhalf# ls
atl2.tar.bz2 modules

   
7. Build source atl2 menjadi paket .deb
   
cn-anjas:/usr/src/etchnhalf# cd modules/atl2
cn-anjas:/usr/src/etchnhalf/modules/atl2# env KSRC=/usr/src/linux-headers-2.6.24-etchnhalf.1-686 debian/rules binary-modules

   Tampilan layar pada saat kompilasi & build menjadi paket .deb kira-kira akan seperti berikut:
   
for templ in ; do \
cp $templ `echo $templ | sed -e 's/KVERS/2.6.24-etchnhalf.1-686/g'` ; \
done
for templ in `ls debian/*.modules.in` ; do \
test -e ${templ%.modules.in}.backup || cp ${templ%.modules.in} ${templ%.modules.in}.backup 2>/dev/null || true; \
sed -e 's/#&KVERS;#/2.6.24-etchnhalf.1-686/g ;s/&KVERS;/2.6.24-etchnhalf.1-686/g ; s/KVERS/2.6.24-etchnhalf.1-686/g ; s/#&KDREV;#//g ; s/&KDREV;//g ; s/KDREV//g ' < $templ > ${templ%.modules.in}; \
done

   Paket deb hasil kompilasi akan diletakkan pada direktori /usr/src. Cek direktori tersebut, bila sudah ada paket atl2-modules-2.6.24-etchnhalf.1-686_2.0.3-3~etchnhalf.1_i386.deb, berarti kompilasi & build menjadi paket debian sudah sukses. Kalau belum, cek output kompilasi, periksa errornya dimana.
   
   
8. Install paket modul atl2:
   
cn-anjas:/usr/src# dpkg -i atl2-modules-2.6.24-etchnhalf.1-686_2.0.3-3~etchnhalf.1_i386.deb

   
9. Cek status antarmuka jaringan eksisting:
   cn-anjas:/usr/src# ip link ls
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 pfifo_fast qlen 1000
link/ether 00:1c:f0:bd:6e:06 brd ff:ff:ff:ff:ff:ff
3: eth1: mtu 1500 qdisc pfifo_fast qlen 1000
link/ether 00:1b:11:74:75:37 brd ff:ff:ff:ff:ff:ff

10: vlan11@eth0: mtu 1500 qdisc noqueue
link/ether 00:1c:f0:bd:6e:06 brd ff:ff:ff:ff:ff:ff

   
   
10. Aktifkan modul atl2 dengan modprobe:
    cn-anjas:/usr/src# modprobe atl2
    
11. cek interface aktif:
    cn-anjas:/usr/src# ip link ls
1: lo: mtu 16436 qdisc noqueue
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

9: vlan10@eth0: mtu 1500 qdisc noqueue
link/ether 00:1c:f0:bd:6e:06 brd ff:ff:ff:ff:ff:ff
10: vlan11@eth0: mtu 1500 qdisc noqueue
link/ether 00:1c:f0:bd:6e:06 brd ff:ff:ff:ff:ff:ff
11: eth2: mtu 1500 qdisc noop qlen 1000
link/ether 00:1e:8c:cc:09:9f brd ff:ff:ff:ff:ff:ff

    interface eth2 (yang menggunakan chipset attansic atl2) sudah aktif.
    Silakan konfigurasi eth2 sesuai keperluan.
    
    
    

Cara mudah trial IPv6

1. Buat account di Freenet6
   
2. Install tspc (apt-get, Debian Etch sudah menyediakan paketnya)
   
3. Konfigurasi tspc:
   Sesuaikan parameter pada file /etc/tsp/tspc.conf: userid dan passwd sesuai account freenet6, kemudian parameter server diset menjadi ipv6.freenet6.net
   
4. restart tspc (/etc/init.d/tspc restart)
   
5. Test ping ke ipv6.google.com
   

Apa yang bisa dilakukan? (namanya juga trial )

• ping6
  
• tracepath6
  
• host/dig ipv6 record pada dns
  
• Browsing via IPv6 (Jika anda memakai Firefox, pastikan parameter network.dns.disableIPv6 diset menjadi False) agar Firefox dapat mengakses Dancing Kame, Dancing Elephant, atau gunung meletus. (ohya, kapan ada dancing horse? ). Situs-situs IPv6 ready lainnya bisa dicari dengan IPv6 google.
  
• Wireshark pada interface tun
