Needless to say: “yet another chroot bootstrapper”

moo is built to help you develop .deb based distributions, and deploy them i.e. via netboot to the target machine.
currently moo only consists of the moo script and /etc/moo.d/. The latter one holds configuration and available packages.
The script will bootstrap a development environment for you, as well as pull updates from the package repository on hakt0r.de.

Just grab moo and execute it like:

usage:
    moo [options] verb arguments
examples:
    moo init
    moo init /home/anx/moo/
    moo install /chroot /media/ubuntu-cd karmic
    moo install /chroot http://blah/ubuntu jaunty #todo
    moo mount /chroot
    moo enter /chroot
verbs:
    init    [prefix=/]
    install target source dist
    remove  target
    mount   target
    unmount target
    enter   target [command=/bin/bash]
    help
options:
    -v      - be verbose

I have been using synergy for a long time now. The only ugly thing about it: it doesn’t encrypt. That’s where ssh comes in. I wrote this handy script a while ago to start ssh tunneled synergy on a client machine:

 #!/bin/sh
port=24800
host=$1

echo -n killing existing synergyc...
killall -9 synergyc
echo done

echo -n killig existing ssh tunnels...
pids=$(ps x |grep ssh|grep $port|grep $host|cut -d' ' -f1)
for i in $pids
	do
		echo -n "killing $i..."
		kill -9 $i;
		echo done
	done

echo -n "Trying to ping $host"
if ping -c1 $1>/dev/null;
 then
	echo done
	echo -n starting ssh tunnel...
	ssh -f -N -L 127.0.0.1:$port:$1:$port $host
	echo done

	echo -n starting synergyc...

	sleep 1
	synergyc 127.0.0.1
	echo done
  else
	echo "failed."
fi
echo done

If you want an ls to be issued each time you cd somewhere:

function mychdir(){chdir $@;ls;}

alias cd='mychdir'

Just add these two lines to your shells .rc file and you are good to go.

Just need the sound of a downloaded tube movie (featuring mplayer and lame)?

#!/bin/bash

 mplayer -ao pcm -vo audiodump.wav $1
lame audiodump.wav -q $2 -b $3 $1".mp3"
rm audiodump.wav
