$ sudo nano /etc/apt/sources.list ; add precise (2 lines)
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo nano /etc/apt/sources.list ; # out quantal (2 lines)
$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get install mc ; worked OK this time 🙂
.

Update users and passwords
Change the root password:
$ sudo passwd root ; enter and confirm a new password
Change the default linaro user password:
$ sudo passwd linaro ; enter and confirm a new password
Create new user:
$ sudo adduser paul ; enter details when prompted, will ask for password
$ sudo passwd paul ; to change PW if not already set up.
$ sudo apt-get install mc ; install mc (midnight commander)
$ sudo apt-get install htop ; install htop
make user home dir and chown
$ sudo usermod -a -G admin paul ; example to add user to existing group
$ id linaro ; reports user info
$ groups linaro ; reports groups containing user linaro
Add user to the sudoers file.
$ sudo adduser sudo
.
Change SSH setup
$ sudo nano /etc/ssh/sshd_config ; change permitrootlogin to no, change port number
.
Set hostname in etc/hostname (mail2) and in etc/hosts (mail2.rcbeacon.com mail2)
. FQDN = mail2.rcbeacon.com
$ hostname ; display hostname
$ hostname -f ; display FQDN
.
Fixed IP
$ sudo nano /etc/network/interfaces
iface eth0 inet static
address 192.168.1.20
netmask 255.255.255.0
gateway 192.168.1.10
Nameserver
$ sudo nano /etc/resolv.conf
nameserver 192.168.1.10
.
SATA – to activate at boot ; should already be active
$ sudo echo “sw_ahci_platform” >> /etc/modules
SATA drive appears at /dev/sda, sda1 etc.
$ sudo mkfs -t ext4 /dev/sda1 ; this will format the drive
Mount before use:
$ sudo mkdir /media/sdd1
$ sudo mount /dev/sda1 /media/sdd1 ; to manually mount
Add to fstab
$ sudo blkid /dev/sda1 ; to determin UUID
$ sudo nano /etc/fstab
UUID=43ce92c0-cf57-4252-b4de-63826a9fbd74 /media/sdd1 ext4 noatime,errors=remount-ro 0 2
.
About time for a reboot
$ sudo reboot
.
How to duplicate the NAND image to the SATA drive:
$ dd if=/dev/nandb of=/dev/sda1 bs=1M
$ sync
