Sockets Related Question...

[batista]

Hi,
I have a socket based client server app.The data is in binary
format....
My question is that i am giving a hard coded port number to connect to
the server machince...
if that port number is closed or blocked by the server machine....
then how would i go about it..I mean how am i going to connect to the
server....
I think ill have to use some kind of proxy sevrer...(may be..just a
blind guess)..

So basically what shud i do if the port number im using is blocked on
the server machine.....
what is the preferred approach...
Thanks..
Cheers,

Bye

Generally one has control over the server ... if this is more of a peer to
peer type app there are lots of methodologies that can be used. The one that
is assured to work is to use what is know as a middle man server ... both
clients connect to the public server and the server routes communications
between them. Generally in P2P systems you try to obtain a peer connection
(much faster) but if you fail you offer the option of falling back to a
middle man server.

There are also protocols such a upnp which many routers support that will
allow you to tell the router to allow data on port xxxx and to forward it to
your program.
