Bug#647866: Network: Packages over hub via bnc not received
Package: linux-base
Version: 2.6.32-38
Severity: normal
Hello,
sorry for this unspecific bug report / question:
After installing debian squeeze the networking does not work in the
following situation:
Situation:
I have a debian patched "Dockstar" (embedded system dockingstation NAS)
box which is connected to a hub.
This hub is connected via bnc-cable (coax) to another hub on which a
linux box (Suse) is connected (router to internet).
If Dockstar tries to connect to internet it "arps" for the gateway MAC
(arp-request is seen on all netork parts with wireshark).
The answer (arp-replay) is also seen an all network part.
The arp table on the dockstar will not be updated by this communication
("arp -n" shows always "(incomplete)" for HWaddress) and continoues arp
request can be seen.
Any network packet directed to the dockstar can be seen on all parts of
the network (this were seen with whireshark) but in debian there is
nothing received.
If I connect the debian-dockstar and the linuxbox over the same hub
without bnc the communication is OK!
It seems NOT to be a hardware problem of the dockstar, because with
original firmware (also a linux) connection over bnc to internet works fine.
I found a information on internet about problem with older hub/network
hardware which inject some sort of incorrect crc errors
http://www.plugcomputer.org/plugforum/index.php?topic=5772.msg18770#msg18770
Is there a way to configure debian linux to ignore such crc errors? What
I do not understand is that all other linux boxes do not have this
problem. Is there a relevant change on kernel module concerning networking?
