This information about HOWTO setup DVB PCI Card for internet (tested with b2c2 chipset) using Ubuntu 5.10 Breezy Badger and Ubuntu 6.06 Dapper Drake. 


== Requirement ==

 * Processor Clock 800 Mhz 
 * HDD 
 * Memory 256Mb
 * Ethernet Card
 * DVB PCI Card   (i used b2c2 from technisat [[http://www.technisat.com]])


== Fresh New Server ==

We need fresh server from ubuntu, so we have to install ubuntu in server mode. For detail instructions howto install in server mode see [[http://www.howtoforge.com/perfect_setup_ubuntu_5.10]]


if you don't like to be root, choose sudo or fakeroot !

i like to be root [[https://help.ubuntu.com/community/RootSudo]]

{{{
$ sudo passwd
$ su
}}} 

put Ubuntu Install CD back into CDROM drive 

as root 
{{{
apt-get install build-essential
}}}


== DVB Packages ==

get the packages from linuxtv.org [[http://www.linuxtv.org/downloads/linuxtv-dvb-apps-1.1.1.tar.gz]]

{{{
tar -zxvf linuxtv-dvb-apps-1.1.1.tar.gz
}}}

make it simple 
{{{
mv linuxtv-dvb-apps-1.1.1 linuxtv
}}}


i have made my own '''patch''' for better display.  [[http://software.prima-info.com/linuxtv-dvb-apps-dvbnet.patch]]

patch and compile them all.
{{{
cd linuxtv
patch -p0 <linuxtv-dvb-apps-dvbnet.patch
make
}}}

if no error report 
copy all off them to /usr/local/bin

{{{
cp util/dvbnet/dvbnet /usr/local/bin
cp util/dvbtraffic/dvbtraffic /usr/local/bin
cp util/scan/scan /usr/local/bin
cp util/szap/szap /usr/local/bin
cp util/szap/femon /usr/local/bin
cp util/dvbdate/dvbdate /usr/local/bin
}}}

== Testing ==

before we do some testing, we need this informations from satellite internet provider (DVB-S) :
 * Satellite band freq (c-band, ku-band) 
 * Polarization
 * Frequency
 * Symbol rate
 * FEC 
 * PID

my configurations is
 * Satellite Band freq = C-BAND
 * Frequency = 3680 Mhz
 * Polarization = Horizontal
 * Symbolrate = 26666 ksym/s
 * FEC = 3/4
 * PID = 4004


{{{
mkdir /root/.szap
cd /root/.szap
}}}


=== Testing : dvbnet ===

what we need here is PID (from dvb internet provider). for example our pid is 4004 (decimal)

{{{
dvbnet -p 4004
}}} 

now you can see your new adapter dvb0_0

{{{
ifconfig dvb0_0
}}}

if you didn't see correct MAC address
{{{
ifconfig dvb0_0 hw ether "$YOUR_MAC_ADDRESS" 
}}}

=== Testing : scan ===

we are ready to scan the transponder now
i assume that satellite dish is on the right pointing 

{{{
cd /root/.szap
echo S 3680000 H 26666000 3/4 > sat.conf
scan -l c-band sat.conf
}}}

this will ok if no error message.

=== Testing : szap ===

this session will create our channels configuration (this is my configuration).

{{{
cd /root/.szap
echo myprovidername:3680:h:0:26666:0:0:7 > channels.conf
}}}

we will tune it now !!
{{{
szap -l c-band -n 1 
}}}

if you see '''"FE_HAS_LOCK"''' ... dvb card is tuned fine !

CTRL+C to stop it !

make it run as daemon

{{{
start-stop-daemon --start -q -b -x /usr/loca/bin/szap -- -l c-band -n 1  
}}}

from now, you can only check it by using femon

{{{
femon
}}}

=== Testing : dvbtraffic ===

testing data capability 

{{{ 
dvbtraffic
}}}

you can also monitor internet packet at dvb0_0  
{{{
tcpdump -i dvb0_0
}}}

you can also using iptraf 


== rc.d "init_dvb" ==

we will make it start automatic every times our pc is re-boot. 

we need this script '''init_dvb''' or get it from [[http://software.prima-info.com/init_dvb]]

and put it on /etc/init.d
