Insert it in a file. I called it stats.sh

chmod a+x stats.sh

and run with ./stats.sh

It updates every second and returns:

• uptime with load
• Disk space and usb disk space
• MB temp
• CPU temp

You can add all you want in there or remove what you don’t need :-)

First Mod: Heatsink with fan!

I noticed that my processor was going up to the 50′s plus degrees when working, so I decided to keep it cool by adding a Heatsing with a FAN. I found one on Amazon.co.uk, specifically designed for Graphics chips, so I thought it would be ok for my Alix. It came with a self-adhesive strip on the bottom which made installation simple. Then after seeing that an 18V supply for the Alix was too high, and hmm… I ran out of adequate resistors to step down the voltage… I hooked on the 5V supply right behind the Serial port! And that ensures i get minimal fan spin, and hence virtually no noise from the fan. The airflow is enough to cool down the heatsink, as there is a noticeable difference when the fan is operational and not.

Update: While compiling the kernel the cpu temperature stays below 42 degrees (Celsius)

Application:

I am now trying to develop a home-made GPS tracker with a GPRS modem to “report back” the location… More on this coming soon!

vol_id /dev/sda1

The string after “ID_FS_UUID=” is the UUID of the drive. Now open your /etc/fstab file and add the following line to the end. Replace the UUID string with your string, your mount point, and customize the other parameters if needed.

UUID=THE-UUID-HERE   /mnt/USBDrive   ext3   user,auto,rw   0   0

To then pass a disk to a xen virtual machine, look at the following lines of the domain config file:

disk        = [
#...root partition and other partitions here...
'phy:/dev/disk/by-uuid/89b976bc-2f66-4b93-abfb-358d6227f8be,sda,w',
'phy:/dev/disk/by-uuid/1871b9a1-8055-4392-8a94-f5407ff37483,sdb,w',
]

basically instead of passing the disk as a /dev/sda1 device, pass it by UUID using the path:

/dev/disk/by-uuid/<the uuid>

Enjoy!

Dropbox stores your files on their server (or in the cloud… depending how you look at it!) and gives you a client which synchronizes a folder on your local computer with the server and any other computer linked to that account. Dropbox also allows sync’ing over LAN, which greatly improves performance for large files if two computers are on the same network! There is a size limit of 2GB for free accounts. Dropbox clients are available for Windows, OSX and even Linux!

iFolder on the other hand allows you to “own” your files and host them on your own private machine. This removes also any space constraints that Dropbox gives you, as the limit is your drive, but adds the problem of being limited by your server’s connection speed, as you are limitied to the badwidth available where your server is. Hosting or colocating will help you overcome that barrier!

Personally I currently use dropbox as I have not (yet) installed a working xen virtual machine with iFolder to deploy on my server. When that happends I might move to iFolder.

Run the following commands:

apt-get update

All done!

3000 -> Disk image size (sparse volume)
disk.img -> image filename

dd if=/dev/zero of=disk.img count=0 bs=1024k seek=3000
mke2fs -j disk.img

Make a 1 Gbyte swap image file
dd if=/dev/zero of=swap.img bs=1024k seek=1024 count=0

Make a temporary directory to mount the image
mkdir mymount

Mount the image
mount -o loop disk.img mymount

Install a system
ARCH = [i386 | amd64]
DISTRIB = [etch | lenny] (or other debian flavours…)
debootstrap --arch ARCH DISTRIB mymount http://ftp.de.debian.org/debian/

Example (64-bit with Lenny)
debootstrap --arch amd64 lenny mymount http://ftp.de.debian.org/debian/

chroot in the environment
chroot mountpoint/

Configure your network through /etc/network/interfaces

# Used by ifup(8) and ifdown(8). See the interfaces(5) manpage or
# /usr/share/doc/ifupdown/examples for more information.

# The first network card - this entry was created during the Debian
# installation (network, broadcast and gateway are optional)
auto eth0
iface eth0 inet static
address ip
netmask mask
gateway gateway
dns-nameservers server1 server2

Change Hostname

echo NewHostName > /etc/hostname

Edit sources.list (make sure you replace etch with YOUR distribution)

Install OpenSSH Server

apt-get install openssh-server

MAKE SURE YOU EXIT THE CHROOT ENVIRONMENT
exit

Unmount the directory
umount mymount

Make a config file. Use this as an example, modifying network and disk paths accordingly to YOUR setup
kernel = "/boot/vmlinuz-2.6.16-xenU"
memory = 256
name = "NewHostname"
vif = ['mac=YOUR_MAC,ip=YOUR_IP']
disk = [ 'file:/xen/MyHostname/disk.img,sda1,w','file:/xen/MyHostname/swap.img,sda2,w' ]
root = "/dev/sda1 ro"

Now start the virtual machine with
xm create CONFIGFILE -c
where CONFIGFILE is your config file duh ;-)

Enjoy!

Stop MySQL server

# /etc/init.d/mysql stop

Start MySQL server without password

# mysqld_safe --skip-grant-tables &

Login

# mysql -u root

Change password (replace XXX with your new root password)

mysql> use mysql;
mysql> update user set password=PASSWORD("XXX") where User='root';
mysql> flush privileges;
mysql> quit

Stop and Start MySQL server

# /etc/init.d/mysql stop
# /etc/init.d/mysql start

Test to see if it works! (Should ask you for your new password)

# mysql -u root -p

Enjoy!
