playing with powertop on my netbook

I know that this via netbook does have issues with powermanagement and i want to digg deeper
to get some sort of power/instructions trace
so i have installed powertop

sudo apt-get install powertop
what is interesting C3 state (sleep) is buggy on this cpu (cache incoherent)
and i see that is really used , it should be disabled by bios but i know that bios is buggy too.

Powertop suggested this
echo 1500 > /proc/sys/vm/dirty_writeback_centisecs

so i have added it in /etc/rc.local
before the exit 0

HowTo boot linux in 5 seconds ,

I will add some optimizations to my everex cloudbook so it can boot faster http://lwn.net/Articles/299088/

This is my QOD:

"We hate splash screens. By the time you see it, we want to be done." The development time that distributions spend on splash screens is much more than the Intel team spent on booting fast enough not to need one.

using everex cloudbook as an wireless router for nokia i810

add an new wireless network from Network Manager and it must be Ad-Hoc and call it foobar
and put the ip 10.0.0.1 to the wlan0 network
with gateway 10.0.0.1
dns 10.0.0.1
and netmask 255.255.255.0

it should look something like this

ip ro show dev wlan0
10.0.0.0/24 proto kernel scope link src 10.0.0.1
ip addr show wlan0

3: wlan0: mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:15:af:54:2a:af brd ff:ff:ff:ff:ff:ff
inet 10.0.0.1/24 brd 10.0.0.255 scope global wlan0
inet6 fe80::215:afff:fe54:2aaf/64 scope link

install dhcpd server
sudo apt-get install dhcp3-server
sudo vi /etc/default/dhcp3-server
INTERFACES="wlan0"
sudo vi /etc/dhcp3/dhcpd.conf
ddns-update-style ad-hoc;
default-lease-time 3600;
max-lease-time 9000;
authoritative;
subnet 10.0.0.0 netmask 255.255.255.0 {
range 10.0.0.2 10.0.0.30;
option routers 10.0.0.1;
option domain-name-servers 10.0.0.1;
}
sudo /etc/init.d/dhcp3-server stop
sudo /etc/init.d/dhcp3-server start

install bind server for dns requests

sudo apt-get install bind9

add in etc/bind/named.conf.options
recursion yes;


allow-recursion {
127.0.0.1;
10.0.0.0/24;
};

allow-query {
127.0.0.1;
10.0.0.0/24;
};

and test it
dig debian.org @10.0.0.1

do the snat

sudo su
echo "1" > /proc/sys/net/ipv4/ip_forward
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE

check the traffic with tcpdump
sudo tcpdump -i wlan0

alternate installer pxe for ubuntu 8.04

if you don't have an usb cdrom or don't want to mess with the usb boot install
then you can install with pxe
seems that it works for me and is quite easy

ps: i borked my cloudbook with an gos -> hardy upgrade but i don't panic i will find a way to put a good os back (or parts of it :lxde/awn ...)
