Posted on December 22, 2015 at 16:19Hello
I try to use
STM32
cube and
LWIP as it comes with
....
Unfortunately
I'm a little
wary
I
enabled
TCP_LISTEN_BACKLOG
to limit
the number of connection
but the
variable
in charge of the
current login
count
accepts_pending
is not
update
properly
It
is
incremented in tcp_listen_input
and
decremented
in
tcp_accepted
and
tcp_pcb_purge
In
this former function
it can not be
decremented
if
the
slot
status is
TIME_WAIT
So
usually
,
if I make a
ftp
connexion , and
I close it
, this
ten
times, I will get
TIME_WAIT
slots that will be
killed
after a while
,
but without
decrementing
accepts_pending
Do
es someone
found a way to
bypass this limitation
?
As the lwip forum is completely dead I ask here, in case ...
Regards
