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. - 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-etchnhalf2.0.3-3~etchnhalf.1all.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/<u>KVERS</u>/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
   dhtestdir
   dhtestroot
   dhclean -k
   dhinstalldirs lib/modules/2.6.24-etchnhalf.1-686/misc
   

   build module
   

   /usr/bin/make -C /usr/src/etchnhalf/modules/atl2 KSRC=/usr/src/linux-headers-2.6.24-etchnhalf.1-686
   make[1]: Entering directory /usr/src/etchnhalf/modules/atl2'<br /> /usr/bin/make -C /usr/src/linux-headers-2.6.24-etchnhalf.1-686 SUBDIRS=/usr/src/etchnhalf/modules/atl2 modules<br /> make[2]: Entering directory/usr/src/linux-headers-2.6.24-etchnhalf.1-686'

   install module
   

   dhinstall atl2.ko lib/modules/2.6.24-etchnhalf.1-686/misc
dhinstalldocs
dhinstallchangelogs
dhinstallmodules

   Paket deb hasil kompilasi akan diletakkan pada direktori /usr/src. Cek direktori tersebut, bila sudah ada paket atl2-modules-2.6.24-etchnhalf.1-6862.0.3-3~etchnhalf.1i386.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.1-6862.0.3-3~etchnhalf.1i386.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 pfifofast qlen 1000
link/ether 00:1c:f0:bd:6e:06 brd ff:ff:ff:ff:ff:ff
3: eth1: mtu 1500 qdisc pfifofast qlen 1000
link/ether 00:1b:11:74:75:37 brd ff:ff:ff:ff:ff:ff
4: vlan15@eth0: mtu 1500 qdisc noqueue

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
2: eth0: mtu 1500 qdisc pfifofast qlen 1000
link/ether 00:1c:f0:bd:6e:06 brd ff:ff:ff:ff:ff:ff
3: eth1: mtu 1500 qdisc pfifofast qlen 1000
link/ether 00:1b:11:74:75:37 brd ff:ff:ff:ff:ff:ff
4: vlan15@eth0: mtu 1500 qdisc noqueue
link/ether 00:1c:f0:bd:6e:06 brd ff:ff:ff:ff:ff:ff

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.
    
    
    

Debian etch doesn't provide sun java package for 64bit architecture by default. You have to use binary from Sun website, or use backports repository. Unfortunately, current java6 package in backports.org suffers from bug #428142. The fix is available, but not yet made into backport repos. So you have to wait for sun-java6 packages update in backport, or use another way: packages from testing repository .

First, you have to install java-common package. apt-get it, the package will install few other packages needed. Second, download these packages:

• sun-java6-bin6-07-3amd64.deb (23MB)
  
• sun-java6-jdk6-07-3amd64.deb (17MB)
  
• sun-java6-jre6-07-3all.deb (6,1MB)
  

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
   

• 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
  
  

Dan Kaminsky has recently discovered security hole on DNS server, the scary part : it's design flaw! A lot of vendor affected (djbdns is one of the lucky few ). Details available here.

Fellow debian admins, you know the drill, apt-get update && apt-get upgrade quick!. Lesson learned from this incident, quoting Kaminsky:

Excellent design protects you against things you don’t have any information about.
