Hi.

Sorry my previous mail to mail list. I never asked help in mailing lists, so it was my first time.

I've problem.
Although everything seems Ok, sat-internet is not working. No pakets recieved through my dvb0_0.

This is the error: :(
argus root # tcpdump -ni dvb0_0
tcpdump: listening on dvb0_0

0 packets received by filter
0 packets dropped by kernel

What I'm doing.

First install drivers from linuxtv.org (last release 1.0.1).
Then, as I have some strings in modules.conf, so to allow modules 
autoload (I do not need to load them manually). Then I put the command:

# dvbtune -f 11088000 -p V -s 19532 -n 3074 
Using DVB card "STV0299/TSA5059/SL1935 based"
tuning DVB-S to L-Band:1073896252, Pol:V Srate=19532000, 22kHz=off

Yes modules autoloaded and driver is configured. Kernel log is:

Strange kernel log. Strange because I can not understand second (01 00 5e 00 00 01) mac addres. The first (00 d0 5c 02 dc df) is myne. Where the second comes from?

So everyhing, except two macs, seems Ok. Then I estabilish vpn connection with my provider.

# pptp sg.dina.ru call sd

Log is:

Nov 24 00:58:31 argus pppd[1319]: remote IP address 81.85.14.1

Some enviroment:
# cat /proc/sys/net/ipv4/conf/dvb0_0/rp_filter 
0

Yes. At this moment I need to set up routes. But pptp for host on the 
other side of vpn connection did it fot me.
argus root # ip route show
81.85.14.1 dev ppp0  proto kernel  scope link  src 195.69.138.21 
81.195.37.16/28 dev eth1  proto kernel  scope link  src 81.195.37.18

127.0.0.0/8 via 127.0.0.1 dev lo  scope link 
default via 81.195.37.17 dev eth1  metric 1 

So I think I shold recieve ping from it through sat.

argus root # ping 85.81.14.1
PING 85.81.14.1 (85.81.14.1) 56(84) bytes of data.

29 packets transmitted, 0 received, 100% packet loss, time 27999ms

But as you could see above there is no connection... No packets on dvb0_0 interface.

Please help me. I am newbie at linuxtv, so maybe I'm doing something wrong. So even comments of my movements can help me.

And the last question. Where I can get documentation on szap. I don't understand if I need It for sat-internet.

And Sorry for my bad English. It is not my native language.
