Hi
I could be wrong in the below description or might have misunderstood
many of the concepts , please correct appropriately.
65535 ports can allowed . So on a machine namely C you can have max
65535 outbound connections
What i was thinking was to send to another machines A and B from the
same port [X] and then when we get data from it to [X] we can the send
it to the correct application using stateful mapping or storing some
information . The machines A and B are unaware of this mapping from
the C machine.
Can we increase it by anymeans in the kernel. Does we have patches for the above
i read on the web that terry lambert has got 1.6 million simultaneous
connection ? how is the way it is done.

yes now lets take 2 dest machines , source ip is fixed , source port (2^16 - 1)
destip is fixed (a.a.a.a and b.b.b.b) ,dest port(2^16 -1) each ,
for a connection we have one port used , say connection 1 is
source ip,port 1 , a.a.a.a port 1
source ip,port 2 , a.a.a.a port 2
.
.
.
source ip,port 65535 , a.a.a.a port 65535
so total of 65535 connections (assume traffic is still going on, a
movie on a slow line dialup or 1kbps )
now if i try to open another connection (assume lots of file
descriptors are present) to a.a.a.a what happens
to b.b.b.b what happens
i think both will not get established as the OS doesn't have any free
source ports or am i wrong
