How to set a static IP in Ubuntu from the shell

Edit
/etc/network/interfaces 
and adjust it to your needs (in this example setup I will use the IP address 192.168.0.100):

# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).

# The loopback network interface
auto lo
iface lo inet loopback

# This is a list of hotpluggable network interfaces.
# They will be activated automatically by the hotplug subsystem.
mapping hotplug
        script grep
        map eth0

# The primary network interface
auto eth0

How to Rip a DVD in Ubuntu Linux

First, install Handbrake:


sudo apt-get install nasm build-essential devscripts fakeroot
mkdir ~/tmp
cd tmp
wget http://apt.cerkinfo.be/pool/main/x264/x264_0.0.20050906-1.diff.gz
wget http://apt.cerkinfo.be/pool/main/x264/x264_0.0.20050906-1.dsc
wget http://apt.cerkinfo.be/pool/main/x264/x264_0.0.20050906.orig.tar.gz
dpkg-source -x x264_0.0.20050906-1.dsc
cd x264-0.0.20050906/
dpkg-buildpackage -rfakeroot
cd ..
sudo dpkg -i *.deb
sudo apt-get install debhelper libgtk2.0-dev jam nasm liba52-dev libavcodec-dev libdvdcss2-dev libdvdread3-dev libfaac-dev libmpeg2-4-dev liblame-dev libmp4v2-dev libogg-dev libsamplerate-dev libvorbis-dev libwxgtk2.6-dev libx264-dev libxvidcore-dev
wget http://handbrake.m0k.org/mirrors/m0k/HandBrake-0.6.2-src.tar.gz
tar -xzvf HandBrake-0.6.2-src.tar.gz
cd HandBrake-0.6.2
jam
sudo cp HBTest /usr/local/bin/handbrake

Next, follow the instructions from the Ubuntu Forums to compile and install MPlayer 2.0 from CVS.


Now we can actually rip the DVD:


cd ~/tmp
handbrake -e xvid -E ac3 -2 -S 1400 -i /dev/cdrom -o MOVIENAME.avi


Finally, split the DVD into two files:


mencoder -ovc copy -oac copy -endpos 700MB -o MOVIENAME.CD1.avi MOVIENAME.avi


The output will finish with something like:

Video stream: 1297.378 kbit/s  (162172 B/s)  size: 638610165 bytes  3937.851 secs  94414 frames

Note the number of seconds (in this case: 3937).


mencoder -ovc copy -oac copy -ss NUMER_OF_SECONDS -o MOVIENAME.CD2.avi MOVIENAME.avi


That's it!
