Socket communication

[ronnin.ubrasky]

Hi all,
I am having two programs that should communicate using sockets.
Program A [has some import data on port 2121] it sends some bytes to
ProgramB.
The programB then process them and send back to A[on port 1234.

The problem is that,when I start program A it gives an error that it
cannot connect to port 2121.
But then if start programB it says that it cannot connect to port
1234..

How can I solve this issue

Sockets are not part of the c++ language, what API/library are u
using ?
if you are using plain BSD/POSIX sockets, you should ask in
comp.unix.programmer.
what sockets are you using, UDP, TCP, UNIX ?
Attach some code ...

cheers,

Hi Paulo,
These are 2 tcp sockets.

I think that whole issue is the server and client problem.
programA expects a server to accept clients on 2121 and programb
expects a server on 1234.

But I cannot start neither one at first because program A is dependent
on program B and program B is dependent on A.

How can I solve this.I am sure that there is way around this.
