how to know socket buffer size of TCP connections dynamically ?
From the tcp man pages, pre-allocated maximum buffer size for a TCP connection can be known.
My interest is to know whether there is a method to find what socket size application called for and
kernel response to it ? As it will change dynamically, is it possible to know buffer size for active TCP connections?
Is there command/utility to find these values by giving a TCP socket identifier or any files to look under /proc?
