Hello,
I created a new tcpdump 3.8.1 with libpcap 0.8.1 (last stable versions at sourgeforge).
I tried to catch ipsec's ESP protocol traffic between two computers. One side is connected with a DSL router and a fixed ip address to the net and the other side is connected with pppoe.
As a test I sent some ICMP packets (ping / pong) between the two computers. The packets were delivered successfully over ipsec but when I run tcpdump at the "pppoe computer" it shows an error at the incoming side:
IP11 truncated-ip - xxyzzy bytes missing!
I found some hints in the net that an old libpcap had this error due to bugs in the handling of ppp packets. But this error should have been fixed a long time ago.
Does anybody have any idea why we still get this error?
regards,
Klaus Schrod
