How to set a static IP in Ubuntu from the shell

bcrow (Basil Crow) — Tue, 10 Jan 2006 03:35:28 GMT

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

iface eth0 inet static

        address 192.168.0.100

        netmask 255.255.255.0

        network 192.168.0.0

        broadcast 192.168.0.255

How to Rip a DVD in Ubuntu Linux

bcrow (Basil Crow) — Thu, 15 Dec 2005 22:24:10 GMT

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!
