hello,
i have a big problem: some servers send a rst-packet or don't answer if i
want to open a connection with them.
this happens with the web-server with ip 15.200.6.123 and my smc-
barricade router/printserver.
if i make a connection from windows or linux with kernel 2.2, it works, with
kernel 2.4, i get a rst or no answer and the connection is closed.
i don't know, what is the difference of the tcp-packets from windows/kernel
2.2 and linux with kernel 2.4. but with kernel 2.4 i have trouble with some
servers.
i check the packets with an analyser and make some test. if i disable ecn
with "echo 0x0 > /proc/sys/net/ipv4/tcp_ecn" it works, with ecn enabled, it
don't work.
goodby

this is a problem on the remote site (old firewall software), nothing we
(linux kernel) can do about it. You might want to inform the owner of the
server about that.

With kernel 2.6.17.13 or higher, you can limit the scaling factor for
that broken host with:
THEIR_IP=1.2.3.4
MY_GATEWAY=5.6.7.8
ip route add $THEIR_IP/32 via $MY_GATEWAY window 65535
which limits window scaling for that destination without interfering
with your other connections.
