Hi again,

I have added sock_.shutdown(SHUT_RDWR) in two places inside the while(1)
loop:
1) right before the sock_.close() call at line 486;
1) inside the if (sock_eof) {...} block of code just before the end of the
while(1) loop.

This seems to solve the problem with lost FINs.

Now I'm trying to stress-test dtntunnel with multiple concurrent iperf
transfers. With
10 flows dtntunnel works well, but when increasing the number of flows to
15 the
already seen weird things happen. The _sending_ iperf starts receiving SYN
packets
from dtntunnel. I think this could happen because of a race condition.
