Try to set socket option SO_REUSEADDR:
i=1;
setsockopt(socket,SOL_SOCKET,SO_REUSEADDR,(char *)&i,sizeof(i));

Subject: [rtl] Off Topic - Ethernet releasing port addresses
Hi,
I'm using RTLV2.3 and kernel 2.2.14. I will most likely upgrade
everything
to the newer versions, but not until the test system is accepted by the
customer and that could be 3 months from now.
I have miniRTL on 8 embedded machines 2 other Linux PC's and 3 Windows
machines on a local network. I have both real-time modules running on
my
linux PC's and user space applications. Specifically, the user space
applications send information to the Windows machines via ethernet
socket
code. I have a set of defined port numbers that the information uses.
My problem is that sometimes when I know I have closed the code out and
I
restart it I get the message
Unable to establish a port Connection: Address already in use.
And sometimes I have to re-boot a linux computer to get rid of this
message
so I can run my code. It might be something I am doing but I have been
seeing this for months now and I haven't come up with a solution.
Any help, ideas, would be greatly appreciated..
