Install Raspbian “wheezy” image

Download image from Raspberry Pi offical website

Mount HOME to HDD

Copy HOME data to disk

$ sudo mkdir /media/new_home
$ sudo mount /dev/sda1 /media/new_home
$ sudo rsync -aXS /home/. /media/new_home/.
$ sudo umount /media/new_home 

fstab

#get disk UUID
$ sudo blkid
/dev/mmcblk0p1: SEC_TYPE="msdos" LABEL="boot" UUID="936C-7122" TYPE="vfat"
/dev/mmcblk0p2: UUID="c1198422-7a7c-4863-8a8f-45a1db26b4f2" TYPE="ext4"
/dev/sda1: UUID="2cd990b5-6c27-4933-95d0-fd00b000fe77" TYPE="ext4"

#modify fstab
$ echo "UUID=2cd880b5-6c27-4933-95d0-fd00b000fe77    /home    ext4    defaults    0    2" | sudo tee --append /etc/fstab

#mount HOMW without reboot.
$ sudo mount -a

Create a sudo user

#create user with HOME directory 
$ sudo useradd -m oopsmonk
#add user to sudo group 
$ sudo adduser oopsmonk sudo 
#set password 
$ sudo passwd oopsmonk 

Install necessary packages

$ sudo aptitude full-upgrade -y
$ sudo aptitude install tmux vim git python-setuptools -y
$ sudo easy_install pip

SAMBA server

$ sudo aptitude install samba
$ sudo cp /etc/samba/smb.conf /etc/samba/smb.conf.bak
$ sudo vi /etc/samba/smb.conf
enable sucurity user
#   security = user
[rpi]
comment = raspberry-pi
path = /home/oopsmonk/
browseable = yes
writable = yes
read only = no

#add smaba user and restart samba server
$ sudo pdbedit -a -u oopsmonk
$ sudo service samba restart

Configre default editor

$ echo "export EDITOR=vim" >> ~/.bashrc
$ echo "export GIT_EDITOR=vim" >> ~/.bashrc
$ echo "export TERM=screen-256color" >> ~/.bashrc
$ echo "alias tmux='tmux -2'" >> ~/.bashrc
$ source ~/.bashrc

Boot from USB Disk

  1. Use dd or Win32DiskImager dump image to both SD card and USB Disk.
  2. Use gparted to expand root partition to full USB disk.
  3. Change cmdline.txt on sdcard from root=/dev/mmcblk0p2 to root=/dev/sda2

     dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 
     console=tty1 root=/dev/sda2 rootfstype=ext4 elevator=deadline rootwait  
    
  4. Plug both sdcard and USB disk into Raspberry Pi, bootup system.

exFat support

Defualt cannot mount exFAT filesystem, why exFAT?

  • NTFS performance is so bad.
  • Single file limited to 4GB in FAT32.

Install exFat:

sudo apt-get install exfat-fuse  

FTP server setup

Install vsftpd

$ sudo apt-get install vsftpd  
$ sudo cp /etc/vsftpd.conf /etc/vsftpd.conf.bak  

Modify vsftpd.conf

$ sudo vi /etc/vsftpd.conf  
anonymous_enable=NO
local_enable=YES
write_enable=YES
force_dot_files=YES  #Add at bottom  

Invoke configuration

$ sudo service vsftpd restart

BT download server setup

Install transmission-daemon

$ sudo apt-get install transmission-daemon  

Modify config file

$ cd /etc/transmission-daemon  
$ sudo cp settings.json settings.json.bak
$ sudo vi settings.json
#Change download folder
"download-dir": "/home/oopsmonk/BT-Download"
#Accept connection from all ip address
"rpc-whitelist": "*.*.*.*"
#Web GUI login account setting
"rpc-username": "oopsmonk"
"rpc-password": "web-login-pwd"
"umask": 2

umask change from 18 to umask: 2. This will enable all users in the transmission group to also write to the file.
Create download folder and change permission for debian-transmission user.
$ mkdir /home/oopsmonk/BT-Download
$ chmod 777 /home/oopsmonk/BT-Download
Reload config

$ sudo service transmission-daemon reload  

Login to Web GUI http://localhost:9091/transmission

Nginx proxy setup for BT server

Why should use proxy??
Some firewall allow connect to internet using 80 port only.
In this case, we can use proxy redirect 9091 to 80 port.

$ sudo install nginx
$ sudo service nginx stop  
$ sudo vi /etc/nginx/sites-available/default
server{
        #listen   80; ## listen for ipv4; this line is default and implied
        #listen   [::]:80 default_server ipv6only=on; ## listen for ipv6
...
        location /bt {
                proxy_pass http://127.0.0.1:9091/transmission;
        }
...
}

$ sudo service nginx start  

Test connection: http://localhost/bt/web/
Do not forget the / in end of URL.

Check device permission.

$ sudo ls -al /dev/snd/*            
crw-rw---T 1 root audio 116,  0 Aug 14 10:49 /dev/snd/controlC0
crw-rw---T 1 root audio 116, 16 Aug 14 10:49 /dev/snd/pcmC0D0p 
crw-rw---T 1 root audio 116,  1 Aug 14 10:49 /dev/snd/seq      
crw-rw---T 1 root audio 116, 33 Aug 14 10:49 /dev/snd/timer

Ha! it’s a permission issue.
Change permission:

$ sudo chmod 666 /dev/snd/*

Solved!
