Command not found

based and thanks to http://feraga.com/node/51

FIRST: detect your device name using dmesg (you should be familiar with this). For example, in my company they bought a comstar 160GB usb external device, and I see it under /dev/sdc1

# Install cryptsetup with LUKS (under linux2.6)
apt-get install cryptsetup

# Create the encrypted partition
cryptsetup luksFormat /dev/sdc1

# Map it to a device mapper
cryptsetup luksOpen /dev/sdc1 comstar

# Give it a FS of your choice
mkfs.ext3 /dev/mapper/comstar

# Make the mount point and mount the device
mkdir /media/comstar
mount /dev/mapper/comstar /media/comstar

# That’s all? -yes. Now, just for test:

# Umount the device
umount /media/comstar

# Close the encrypted partition
cryptsetup luksClose /dev/mapper/comstar

# Open and mount again, etc…
cryptsetup luksOpen /dev/sdc1 comstar
mount /dev/mapper/comstar /media/comstar

Typical libc6-dev missing, example:

$ sudo invoke-rc.d varnish start
Starting HTTPd accelerator: /usr/bin/ld: crti.o: No such file: No such file or directory
collect2: ld returned 1 exit status
pclose=256
Internal error: GCC returned 0×0100
invoke-rc.d: initscript varnish, action “start” failed.

Solution:

$ sudo apt-get install libc6-dev

Read sudo msg once or twice a year:

“We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.”

Finally I feel comfortable with my desktop.
I was using xmonad for a couple of months but I wasn’t liking with the ways I had to show a desktop bar, I was using dzen2 but with no time to put all the gadgets and things I need / like. So in the first free time I had I tried it with GNOME. Try it you too! it’s very easy to configure (with xmonad 0.7) Ah! one last important thing: if it doesn’t work at the first attemp, try to remove your .gnome and .gnome2 directories
