Hi, > I'm loosing a lot of IP packets with this version. Any > suggestions how to fix this?
I still haven't found a solution for my problem or even a way how to track it down. I'm using a Debian Kernel 2.4.19, and a full featured DVB card with a Conax CAM module. vdr 1.1.25 is tuning to "Data only:12633:h:S19.2E:22000:0:0:0:0:0:0:0:1001", that means no filters are set for audio/video pids. A self written plugin (not released, yet) creates the DVB network interface and sets the network pid 1014. The DVB driver from 2003-04-13 had no problems with lost ip packages. At least all of the errors were recoverable. But this version crashes after some days of continous reception and that's the reason why I have to update to a newer version. Even the kernel software-watchdog is unable to reboot the computer in this case. The CVS version of the DVB from 2003-10-06 driver looses IP multicast packets (UDP). >From a total of 4922 packages I'm loosing 368 packages. I tried both firmwares (Root and Root-icam) with the same result. This versions runs very stable for me. The application C-Terminal from Castify Networks can resolve 346 of the lost packages with its own error correction algorithm, but that still means 22 unrecoverable lost packages. The part from /var/log/messages, where the multicast filters are set: Oct 6 22:53:13 atu-dev kernel: dvb0_0: set_mc_list, 2 entries Oct 6 22:53:13 atu-dev kernel: dvb_net_feed_start: rx_mode 1 Oct 6 22:53:13 atu-dev kernel: dvb_net_feed_start: alloc secfeed Oct 6 22:53:13 atu-dev kernel: dvb_net_feed_start: set secfilter Oct 6 22:53:13 atu-dev kernel: dvb0_0: filter mac=00 d0 5c 02 cd 26 Oct 6 22:53:13 atu-dev kernel: dvb0_0: filter mask=ff ff ff ff ff ff Oct 6 22:53:13 atu-dev kernel: dvb_net_feed_start: set multi_secfilter[0] Oct 6 22:53:13 atu-dev kernel: dvb0_0: filter mac=01 00 5e 02 02 0a Oct 6 22:53:13 atu-dev kernel: dvb0_0: filter mask=ff ff ff ff ff ff Oct 6 22:53:13 atu-dev kernel: dvb_net_feed_start: set multi_secfilter[1] Oct 6 22:53:13 atu-dev kernel: dvb0_0: filter mac=01 00 5e 00 00 01 Oct 6 22:53:13 atu-dev kernel: dvb0_0: filter mask=ff ff ff ff ff ff Oct 6 22:53:13 atu-dev kernel: dvb_net_feed_start: start filtering Please can anybody give me some hints how to resolve the problem. Which additional informations is needed? Does anybody have a similar setup (full featured DVB card with IP data reception), that works? The old driver version works, but crashes very often, therefore I think it must be possible to get this setup running. Have there been any general changes in the driver, that can lead to ip packet loss (performance/timing issues or throwing away TS packages because of bad checksums) or is this only related to the network part of the driver?
