This script saves the video streams from the Arte +7 liberty local.
You only need to run the script with the main url of your target video stream, as example:

Syntax: ./arte_plus7_downloader.sh "url"
Example: ./arte_plus7_downloader.sh "http://plus7.arte.tv/de/1697660,CmC=3024668,scheduleId=3004936.html/"

Simply to use, no need to explain it completely...

arte_plus7_downloader.sh:

#!/bin/sh

# check for syntax
if [ $# -eq 0 ] ; then
echo "Syntax: ${0} \"url\""
echo "Example: ${0} \"http://plus7.arte.tv/de/1697660,CmC=3024668,scheduleId=3004936.html/\""
exit 1
fi

# download from:
URL="${1}"

# save location
LOCATION="/Download/Arte"

# html dump
HTMLTMP="/tmp/arte_tmp"

# date of today
DATE=`date +%y%m%d`

# check if html dump file exist
if [ ! -e ${HTMLTMP} ] ; then
# create file
touch ${HTMLTMP}
else
# if file exist deleted contents
echo "" > ${HTMLTMP}
fi

# get main page with video info
curl -m 5 --connect-timeout 5 -# ${URL} > ${HTMLTMP}

# parse title out of the html dump
TITLE=`cat ${HTMLTMP} | grep -e 'meta name=\"Title\"' | sed 's/ .*\=//g;s/.-.ARTE+7.*>//g;s/\"//g;s/;//g;s/ /_/g'`

# parse for wmv/mms container file
WMV=`cat ${HTMLTMP} | grep -e 'availableFormats.*PG_HQ_DE.wmv' | sed 's/availableFormats.*\=//g;s/\"//g;s/;//g;s/ //g'`

# get container file
curl -m 5 --connect-timeout 5 -# ${WMV} > ${HTMLTMP}

# get mms stream address
WMV=`cat ${HTMLTMP} | grep -e 'PG_HQ_DE.wmv' | sed 's///g;s/ //g'`

echo "${TITLE} - ${WMV}"

# get the dump with mplayer
mplayer -dumpstream "${WMV}" -dumpfile "${LOCATION}/${TITLE}-${DATE}.wmv"

# error handling
if [ $? = "1" ] ; then
echo "Error! Retrying download"
"${0}" "${URL}"
fi

echo ""

What is missing/ToDO:
+ a better error handling
+ self fetching RSS Feed script to automate download process - something like bashpodder
+ further description and options

Need vertical splits in screen?

Get the actual source of screen:

wget http://ftp.gnu.org/gnu/screen/screen-4.0.3.tar.gz

Then get the patch from http://fungi.yuggoth.org/vsp4s/:

wget http://vsp4sdl.yuggoth.org/wrp_vertical_split_0.3_4.0.2.diff.bz2

Extract the downloads:

tar xvf screen-4.0.3.tar.gz
bunzip2 wrp_vertical_split_0.3_4.0.2.diff.bz2

Then apply the patch:

patch -p1 < wrp_vertical_split_0.3_4.0.2.diff

Compile and build screen from scratch:

./configure
make
make install

And to finish it add following line to the ~/.sceenrc config:

bind 'V' vert_split

To create a vertical split press 'C-a V'

Done and have fun with it!

If you want to scroll in the alternative text buffer of screen in xterm just add

termcapinfo xterm ti@:te@

to your .screenrc config file.

[Example with eth0]

ifconfig eth0:1 10.0.0.1

This line add a secound network interface for 10.0.0.0 to your nic. The rest of the preferences are automatic made. So if you don't need special preferences like gateway and co. there is nothing more to do.

You can check it with route -n if it worked...

[Basic]
# One server, two clients (IP unknown)
# Forwarding port from server to client

(IPs of clients change regularly and aren't known, between client A and B are Firewalls, which don't allow connections from outside)
Client A is allowed to connect to the server, but not to client B.
Client B is allowed to connect to the server, but not to client A.

[Solution]
Client B makes a connection to the server to forward a remote port to the local host and hold this connection all the time (cron-script).
Client A makes a connection to the remote port on the server and will be forwarded to the client B.

[Why?]
I use this to forward a SSH connection from work home, or the other way around.

[Example with SSH]
The SSH daemon runs also on both clients and on the server.
So I forward a port from the server to my clients ssh port.

[Client B]
ssh -R 2048:localhost:22 user@example.com

[Client A]
ssh -P -L1234:localhost:2048 user@example.com
ssh -p 1234 localhost

[crontab -l]
# check connection to the server
*/2 * * * * /root/fwd_ssh > /dev/null 2>&1

[Cron-Script - fwd_ssh]
#!/bin/sh

# $REMOTE_HOST is the name of the remote system
REMOTE_HOST=user@example.com

# $REMOTE_PORT is the remote port number that will be used to tunnel
# back to this system
REMOTE_PORT=2048

# $CMDDHCPCD dhcpcd command
CMDDHCPCD="/sbin/dhcpcd -d -t 30 eth0"

# $CMDSSHD sshd command
CMDSSHD="/etc/rc.d/rc.sshd start"

# $COMMAND is the command used to create the reverse ssh tunnel
COMMAND="ssh -f -q -N -R ${REMOTE_PORT}:localhost:22 ${REMOTE_HOST}"

# Is the dhcpcdaemon running?
pgrep -f -x "${CMDDHCPCD}" > /dev/null 2>&1 || ${CMDDHCPCD}

# Check for relevant process ($COMMAND)
pgrep -f -x "${COMMAND}" > /dev/null 2>&1 || ${COMMAND}

# Check for sshd
pgrep -f -x "/usr/sbin/sshd" > /dev/null 2>&1 || ${CMDSSHD}
