howto: pfsence 2.0 usb installer

UNetbootin and PhysDiskWrite did not worked for me but I've finally managed to create realieable Pfsence usb-installer on Win7 enviorement. The procedure is as follows:

Preparation

• - Create new folder e.g: c:\foo
• - Download http://pfsense.mirror.range-id.it/downloads/pfSense-memstick-2.0-RELEASE-i386.img.gz and extract it with your favorite gz utility
• - Download flashnul commandline utility http://shounen.ru/soft/flashnul/ (kudos to George Shuklin)
• - Place all three files (flashnul.exe, flashnul.conf and pfSense-memstick.img) within this folder you just created previously.

Installation process

• - Create shortcut on desktop for C:\Windows\System32\cmd.exe
• - Right click and start "run as Administrator" and change directory to: cd c:\foo
• - Carefully observe which USB drive has been assigned to your drive latter and verify with:  

c:\foo> flashnul.exe -p 
Avaible physical drives:

1 size = 8010194944 (7639 Mb) 

Avaible logical disks: 
C:\ 
D:\ 
E:\ 

Press ENTER to exit.

Start writing raw image

c:\foo> flashnul.exe e: -L pfSense-memstick.img

yo may now verify installation by booting from your USB drive.

Install standalone tracd on Lacie Networkspace2

Before continuing your hardware should be loaded with (custom Capsule)

By default python installation on Lacie does not come with setuptools, so you need to adjust python enviorment additonally:

# mkdir -p /usr/include/python2.6/
# curl -k https://dev.openwrt.org/raw-attachment/ticket/8032/pyconfig.h >
foo
# mv foo pyconfig.h

# mkdir -p /usr/local/src && cd /usr/local/src
# wget http://peak.telecommunity.com/dist/ez_setup.py 
# python ez_setup.py
# easy_install Genshi

Install Trac
# wget -c http://ftp.edgewall.com/pub/trac/Trac-0.12.2.tar.gz
# tar zxvf Trac-0.12.2.tar.gz
# cd Trac-0.12.2
# python ./setup.py install

Test: start Trac test enviorment on port 3333
# mkdir -p /tmp/test/trac
# trac-admin /tmp/test/trac initenv
# tracd -d --port 3333 /tmp/test/trac
# svn co svn:///localhost:3333/test

That's about all.
For autostart consider creating adding suitable `tracd` with `-d` daemon parameters within /etc/init.d/bootmisc do_start function. You may also consider viewing one of my previous posts running tracd on Debian: http://web.trakic.com/2010/06/trac-as-standalone-server-on-debian.html

R project - my first impressions

I' ve just installed R on my computer.
Interesting project, although my old Matlab code cannot be used directly without further modifications.
Also plugin/package infrastucture it bit annoying: after base installation you need to know what each package provides but you need to install it first.

Debian chroot install on LaCie Network Space 2

Finally I have managed to install Debian testing and access it via ssh on Lacie Network Space 2.

The procedure is as follows:

1) On your existing debian machine create chroot enviorment:



# debootstrap --arch armel testing ./testing-armel-chroot


2) Rsync the whole bundle on your NS2, eg.: /shares/MyShare/testing-armel-chroot

3) Symlink chroot destination /shares/MyShare/testing-armel-chroot to /debian

4) Create chroot one-time wrapper script in order to mount chroot enviorment correctly and prepare networking:


# cat /etc/chroot.debian

#!/bin/sh
ROOTFS=/debian
if test "$(whoami)" = "root" ; then
DEV=eth0:2
IP=192.168.1.10
ifconfig $DEV down
ifconfig $DEV $IP up
mount -t proc proc ${ROOTFS}/proc
mount --bind /dev ${ROOTFS}/dev
chroot ${ROOTFS} su root -c "/bin/bash $*"
fi


5) Done.
You may now access to your Debian chrrot either via chroot:


# chroot /debian /bin/bash


Or yoy can even start ssh deamon by adjusting dropbear configuration file:


# cat /debian/etc/dropbear/run

#!/bin/sh
exec 2>&1
OPTS="-F -E -p 2022 "
exec dropbear -d ./dropbear_dss_host_key -r ./dropbear_rsa_host_key $OPTS

# sh /etc/chroot.debian /etc/init.d/dropbear restart



Here are some interesting outputs from such setup:

(chroot-)root@nas2:~# arch
armv5tejl
(chroot-)root@nas2:~# uname -ar
Linux nas2 2.6.22.18 #1 Thu Nov 4 17:37:15 UTC 2010 armv5tejl GNU/Linux
(chroot-)root@nas2:~# cat /etc/debian_version
6.0


Also X applications runs very well:
