Wireshark, netperf and sctp problem

[frank.schuster01 at web.de]

Hello,

I have a problem with my little network test.
I want to test sctp between ubuntu and freebsd.
On ubuntu I wrote a iptables rule which delete every tenth (10) data package. Freebsd has no firewall rules.
But only ubuntu sends data and freebsd only acknowledge this data (i did the test with netperf).

On the sending side (ubuntu) I see in wireshark 24 data packages, and on the receiving side (freebsd) I saw 82 packages.
But I can't explain, why freebsd receives more packages as delivered from ubuntu? (I have currently only one freebsd system).

Any ideas or  something additional notes to help me?

Is the problem by wireshark or the kernel implementation?

Regards
Frank
