Hi justein,
I think the explantion is simple.

SERVER SHOULD ALWAYS RUN FIRST.
Thats why ur getting the error.

Make Vxworks as server , then u can start the vxworks first and see.

All the best.

Thanks vijay,
but the problem is that this is a dual system configuration where I don't
necessarily know which system is running first.

I need the server on the Windows XP machine, as this is also functioning as
server for several other computers. So I need some way of figuring out how
to connect the VxWorks to the server even though the first few attempts may
happen while the server is not ready yet...

Thanks!

Hi,
in case anyone is interested, here is the solution:

If no success in connect, close the socket. Then reopen socket and try
connect again.

I simply moved the sFd=socket() call into the while loop, and made sure I
closed the socket if no connect. Now it works well.

Hi jostein, would you please let me know your email cause I have some question about the Socket connection between vxworks and windows for my project.
