[linux-dvb] Re: DVB-s Satellite Internet help needed.

[amen ra <mylordra@yahoo.com.au>]

Can people please comment on my attempts so far and
help me fill in the blanks and any errors
This what I have so far on HOW TO get a DVB-s card
working under Linux 8.0
Install drivers - not sure of the best version to use
cd /usr/src
tar -zxvf siemens_dvb-0.9.4-2002-06-23.tgz
mv siemens_dvb-0.9.4-2002-06-23 DVB
ln -s linux-2.4 linux
cd /usr/src/linux
After copying the correct config file for the kernel
make oldconfig  #(is this needed ?)
make mrproper  #(is this needed ?)
cp configs/kernel-2.4.18-athlon.config .config
make dep
make bzImage  #(is this needed ?)
make modules  #(is this needed ?)
I built the drivers using the instructions in README
and INSTALL
cd /usr/src/DVB/driver
make
make insmod
lsmod

Install dvbtune -
http://www.linuxstb.org/dvbtune/index.shtml
cd /usr/src
unzip dvbtune then:
tar -zxvf dvbtune-0_3.tar.bz
cd dvbtune-0.3
make
cp dvbtune /usr/local/bin
then Add network interface and receive MPE on PID dpid
(PID=1951)
./dvbtune -n 1951
ISP Details: Freq 12336 V, SR 30000, FEC 2/3, PID 1951
./dvbtune -f 12336000 -s 30000 -p v -D 0
*****************************************************************
./dvbtune (to list options remember to use the Diseq
option when the switch is installed)
Usage: dvbtune [OPTIONS]
The following options are available:
-c [0-3]   Use DVB device [0-3]
-f freq    absolute Frequency (DVB-S in Hz or DVB-T in
Hz)
           or L-band Frequency (DVB-S in Hz or DVB-T
in Hz)
-p [H,V]   Polarity (DVB-S only)
-t [0|1]   0=22kHz off, 1=22kHz on
-I [0|1|2] 0=Spectrum Inversion off, 1=Spectrum
Inversion on, 2=auto
-s N       Symbol rate (DVB-S only)
-D [0-4]   DiSEqC command (0=none)

-V vpid    Set video PID (full cards only)
-A apid    Set audio PID (full cards only)
-T ttpid   Set teletext PID (full cards only)
-pnr N     Tune to Program Number (aka service) N

-i         Dump SI information as XML
-x         Attempt to auto-find other transponders
(experimental)
-m         Monitor the reception quality
-n dpid    Add network interface and receive MPE on
PID dpid
*****************************************************************
When dvbtune has been executed the DVB card is
available like a normal network device.
Have to set FEC to 2/3
Have to set LNB LOF low, switch and high to 11300000
Activate the interface it first (maybe using "ifconfig
-a dvb0_0")
Then set an IP address and MAC address with the
command
ifconfig dvb0_0 192.168.4.1 hw ether 00:01:02:03:04:05
up
Now look at /var/log/messages
tcpdump -ni dvb0_0
Next setup routing for ppp connection and firewall
(iptables) and Internet connection sharing (NAT)
I think that the outgoing packets thru ppp0, ppp1, or
ppp2 Source IP address needs to be set to the IP
address of the DVB-s card interface dvb0_0 somehow
echo "0" > /proc/sys/net/ipv4/conf/dvb0/rp_filter
How to make the settings stick after reboot
