Re: malformed captured packets

I use at home an DSL connection (stable Gentoo system),
current kernel is 2.6.22-gentoo-r5.

I attached 2 pcap files with the communication of the KDE program kscd with the
CDDB server freedb.org, sniffed from interface ppp0 and eth0 respectively.

The sniffed network stream over the ppp0 interface looks _always_ fine whereas
the sniffed packets from the eth0 always looks bad :-(

I don't undestand why the ppp0 stream is ok, whereas the eth0 stream has always
a malformed package (eg #13 in kscd_eth0.pcap) which contains the content of the CD.
And I'm really confused about the fact, that within a LAN I did not have a
malformed packet.

I discussed it
here http://www.wireshark.org/lists/wireshark-users/200707/msg00187.html
and here http://bugzilla.kernel.org/show_bug.cgi?id=8793 and many different
places in the past but w/o success.

Any explanation are appreciated.

Can you provide more information about the problem, please? Are you 
using a simple DSL modem with PPPoE, such that the ppp0 interface is 
that of the pppd started by a local PPPoE server? Is this a problem only 
with packet capture or are you seeing actual data corruption? Did this 
work with previous kernels? What is the network topology related to the 
DSL interface?
