is especially useful for TCP servers which must specify the receive
socket buffer size before the connection is made so that the connection's
window scale factor can be properly advertised.
Example /etc/inetd.conf configuration line:
shell stream tcp,rcvbuf=1m nowait root /usr/libexec/rshd rshd
That line will cause the rshd to advertise a 1 megabyte window, which could
improve the performance of an rcp in some situations.
