I'm looking for people who may have the same problem as I.  Let me
describe it.

When I'm at my parents house using the OpenBSD laptop, my TCP
connections from there experience degragations, lost and dropped packets
somewhere in the Internet, this causes retransmissions in TCP which I
have tracked.  The other computers in that household are Linux and Mac
OS X and do not have these symptoms.

There is hints that it may be the home router a Fritz!Box but I have
compared tcpdumps and packet dumps from the routers packet dump
interface and I do see the packets dropping before it (unless that
router lies in its pcap file), so unseen by it.  Causing me to think
that the degragation is in the upstream network.

That upstream network happens to be Deutsche Telekom, germanys largest
provider.  I know it may sound crazy that these people degrade TCP,
based on some TCP OS signature, but could it be?

So I'm looking for more people who use DTAG who have experienced
degragations (mostly noticed in running screen or tmux and having
switched windows and it's doggedly slow due to retransmissions).  What
sort of home router do you use?

I'm also looking for Fritz!Box users with FritzOS 6.x firmware who have
these degragations and aren't necessarily on DTAG's network.

I guess I could change routers to find out but what if it's a
conspiracy?  Also I have created gif tunnels and experienced no
degragations which to me says there is a Deep packet inspection on
native TCP packets, somewhere, and the degragation.

I invite the company Genua to look into this too since they use OpenBSD
afaik and if they are losing customers over this it could be bad for
their core business.

BTW tickets to DTAG were opened and closed, and opened to AVM the router
manufacturer but closed on my behalf because the packet dump revealed
that drops were not on that router.
