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
