Disk Encryption and the Acer Aspire One

The Acer Aspire One 150l comes with a seagate ST9120817AS sata drive.
But unlike the Via C7, the Intel Atom has nothing like padlock.

You can however modprobe

twofish_i586
aes_i586


I forced the intel rng to load after an otr request locked my book for several minutes… haven’t tested yet if it helps.

intel_rng no_fwh_detect=-1


The following benchmarks were not done with great care, they are by no means repsrentative. The system wasn’t in single mode and the tests were only repeated once or twice.

Note: Today, without changing really anything, the pure lvm test get 55mb/s buffered disks reads and the 128bit twofish benchmark 11mb/s

jmb38x script on acer aspire one

I took a long look at the original jmb38x_d3e.sh from linpus linux lite and did some modifications.
If you start it with ‘watch’ it will put the card into powersaving (d3e?) mode, only if the laptop is on battery and no cards have been inserted.
I still have to suspend/resume before any cards, inserted after boot, are recognized.

#!/bin/bash

linpus linux goodbye

Well, the preinstalled linpus linux kind of died on me. I tried to install debian over usb, but 64mb is not enough. I tried PXE, which worked fine. But debian stable crashed while installing (kernel too old), debian testing didn’t boot, because of kernel oops on realtek nic module (kernel too new), debian unstable is the same netboot.tar.gz as testing.

Ubuntu PXE install worked just fine (kernel messed up just right).

Currently I’m copying useful stuff from the old linpus linux to make everything work again.

This is the most advanced guide i found  https://help.ubuntu.com/community/AspireOne

I created two scripts:

/etc/init.d/local-acer, using the strange jmb38x_d3e.sh from the original linpus

acer aspire one 150L

Clicked myself an Acer Aspire One 150l yesterday. I just unpacked it this morning.
After my thinkpad x30 I didn’t really want to go with small laptops again, but the acer is so damn cute.  I would have bought a pink one, or at least a white one, but pink isn’t available and everyone wants a white acer, so i had to buy blue. pink is great, pop is good for you.

Hardware

I really like the hardware, 120gb SATA drive, 1GB ram. Other netbooks in the same class come with Windows XP, but there is no microsoft tax on the A150L.
Well, the fan is kind of loud. I tried to update the bios using http://unetbootin.sourceforge.net/ and an usb stick, but xxd diff shows no difference to the original bios. So i guess i’ll have to wait for a better one.
The display is great, brilliant colors and not wobbly like the msi winds, judging from the reviews on youtube. Touchpads make me feel uncomfortable, but no one likes trackpoints anymore, guess i’ll have to learn some mad touchpad skillz.

Linux

Once inside the linplus lite linux I activated xfces right-click menu, installed a modern terminal and pulled some software with yum and pirut.
Since my last redhat admin job in 2001, I forgot about redhats rpm format being a total waste of time. Maybe i thought yum might be to rpm what apt was to deb, but it really isn’t.
Anyway i don’t want to waste all this nice acer addons, the desktop is great. Maybe i’ll port some of it to debian (http://wiki.debian.org/DebianAcerOne).

Oh, about acers linplus lite linus:
* the ‘acer root’ hack actually consists of pressing alt-f2 and using sudo in a xterm
* the mail client is not really good with imap, no folder support… evolution isn’t installable because of some fc8 gnome dependency vs acer package conflict
* bootblock is lilo.. and why is there a ntfs bootblock on /dev/sda1
* only one 120gb partition on sata drive, but home mounted with aufs
* xfce compiz looks great though
* no firefox3, which is a real dealbreaker, well, and the fan
* no shadow passwords enabled
* X listening on port 6000…
* root actually uses a md5 password.
* no ipv6 support in kernel
* default screensaver kind of lame

I installed ssh, zsh and some other usefull packages (wireshark, lsof, …)
