Thank you very much. Using truss and the info dialog, I found out about the
folders Wireshark is looking into for plugins.
Now it is working as expected!

Bye,

Jo

Two possible reasons:

1) The data segments got duplicated in transit, or retransmitted due
to the sender not receiving an ACK in what it considered a reasonable
time. The receiver may ack each duplicate if they all do eventually
arrive.

2) The data segments got re-ordered in transit, so the receiver got a
segment later than the one it was expecting next. These days it can
reply using Selective Acknowledgement, where the ACK field itself
contains the latest *contiguously* received sequence number (so will
appear to stay the same), but the SACK field (shown under the TCP
Options section in Wireshark) show what other non-contiguous data it
has received. Then if the sender later decides it does need to
retransmit it only has to "fill in the gaps" rather than send the
entire window from the ACK point on. (I believe Wireshark displays
this as a "Duplicate ACK" rather than out-of-order or such, or at
least used to, apparently it doesn't notice the SACK options changing
each time.)
