Install "Network controller: Intel Corporation PRO/Wireless 2200BG (rev 05)" di kernel 2.6.13

Assalamu'alaikum Warahmatullahi Wabarakatuh

Setelah berhasil compile kernel 2.6.13, seperti biasa ... wi-fi jadi gak berfungsi lagi. Oprek lagi, dan berhasil jalan.

1. Download ipw2200-1.0.6.tgz
:/usr/src$ wget -c [url file ipw2200-1.0.6.tgz]

2. Ekstrak
:/usr/src# tar -xvvzf ipw2200-1.0.6.tgz

3. Download ieee80211-1.0.3.tgz
:/usr/src$ wget -c [url file ieee80211-1.0.3.tgz]

4. Ekstrak
:/usr/src# tar -xvvzf ieee80211-1.0.3.tgz

5. :/usr/src/ieee80211-1.0.3# make

6. :/usr/src/ieee80211-1.0.3# make install

7. :/usr/src/ieee80211-1.0.3# make IEEE80211_INC=/lib/modules/`uname -r`/build/include install

8. :/usr/src/ipw2200-1.0.6# make

9. :/usr/src/ipw2200-1.0.6# make install

10. Tambahkan module ipw2200 ke kernel
:/usr/src/ipw2200-1.0.6# modprobe ipw2200

11. :/usr/src/ipw2200-1.0.6# ./load

12. Wi-fi dikenali kembali
:~# iwconfig

13. Edit file interfaces
auto lo
iface lo inet loopback

auto eth1
iface eth1 inet dhcp

wireless-essid diisi essid hot spot atau acces point
wireless-key s:diisi essid key nya

14. Restart networking
:~# /etc/init.d/networking stop
:~# /etc/init.d/networking start

15. Terhubung ke Internet

Upgrade ke Kernel 2.6.13

Assalamu'alaikum Warahmatullahi Wabarakatuh

Hari ini coba upgrade ke kernel 2.6.13 di Acer Travelmate 4002 NLMi

1. Download source kernel linux-2.6.13.tar.gz
:/usr/src$ wget -c [url source linux-2.6.13.tar.gz]

2. Ekstrak
:/usr/src# tar -xvvzf linux-2.6.13.tar.gz

3. Copy file (misal) config-2.6.12 & rubah menjadi .config
:/usr/src/linux-2.6.13# cp /boot/config-2.6.12 .
:/usr/src/linux-2.6.13# mv config-2.6.12 .config

4. Dibiasakan membaca HELP kalo ada pilihan yang gak ngerti, nulis lspci & dmesg bisa sangat membantu. Kernel sebelumnya (2.6.12) itu hasil memilih dengan sangat "selektif" dan cukup lama. (Hampir) semua yang diperlukan di include di kernel & (sangat) sedikit yang [M] modularizes features.

:/usr/src/linux-2.6.13# make menuconfig

Lanjut ... (singkatnya)

dst.
Masih banyak lagi. Intinya, pilih seefisien mungkin yang di include ke kernel.

Save Configuration to an Alternate File
.config < Ok >
Do you wish to save your new kernel configuration? < Yes >

6. :/usr/src/linux-2.6.13# make

7. :/usr/src/linux-2.6.13# make install

8. Install kalo ada sebagian dari kernel yang dijadikan modules
:/usr/src/linux-2.6.13# make modules_install

9. Update Grub (manual)
:/# vim /boot/grub/menu.lst

Tambahkan (misal):
title Debian GNU/Linux, kernel 2.6.13
root (hd0,1)
kernel /boot/vmlinuz root=/dev/hda2 nomce psmouse.proto=imps quiet
initrd (hd0,1)/boot/initrd.
savedefault
boot

10. Reboot with the new kernel and enjoy

KDE 3.4.2 (can't login to root)

Assalamu'alaikum Warahmatullahi Wabarakatuh

Hari ini coba upgrade KDE ke 3.4.2.

1. Ubah sources list ke experimental & sid (sebelumnya testing & unstable).
:~# apt-get update && apt-get dist-upgrade

2. Setelah selesai instalasi, logout. Lalu jalankan Xwindow
:~# startx

3. Dan... wew, gak jalan. Restart.
:~# reboot

KDE 3.4.2 berjalan dengan baik. Tapi ... gak bisa login langsung ke root. Walah, mana lupa file apa yang harus di edit biar bisa login ke root. Sebelum-sebelumnya udah beberapa kali nemuin masalah ini setiap upgrade KDE. Coba nyari di direktori /etc/pam.d/, file /etc/securetty, di direktori /etc/security/, di Control Centre di desktop, dsb. Akhirnya setelah googling, ketemu. Ternyata di file kdmrc.

4. Di Terminal Program, login ke root
:~$ su
Password:

5. Edit file kdmrc
:~# vi /etc/kde3/kdm/kdmrc

Ubah baris
AllowRootLogin=false

menjadi
AllowRootLogin=true

6. Logout & login langsung root
