Is there a way to set the mss for a socket ? Like you can do
in linux with setsockopt(TCP_MAXSEG) ?
So i can set the maximum size of packets (or sort of) from a
simple userland program.
Depending on exactly what you need to accomplish, you may
find something useful in this thread from last August in
freebsd-questions@
setting the other end's TCP segment size
Very informative thread, thanks.
This thread show me that TCP_MAXSEG is implemented in freebsd but don't
work. You can set the setsockopt(IPPROTO_TCP, TCP_MAXSEG), wich will set
the
tp->t_maxseg, but this value is recalculated at tcp_input, so in short, you
cannot set the max segment size for a socket.
I've posted a completly wrong patch (from style point-of-view - and using
SOL_SOCKET instead of IPPROTO_TCP), but with that patch i'm able to set the
mss in iperf.
this thread shoud be in FreeBSD-net@ so tha the right people see it
many developers do not read hackers every day as it tends to overload
them.
Many thanks,
Luiz
