Good day!

i am experimenting with epics tcp socket capabilities using asyn driver. having done some reading , install the asyn package and the epics sequencer as well. under the asyn directory there is an testIPServer directory with a read me file that tell to setup the SNCSEQ in the realese variable to use the sequencer capabilities. this folder provide a ipSNCServer.st and ipEchoServer.c files that i am trying to incorporate to my application to have a server  listening  at a specific port.
now, i build my application and under top/xxxApp/src i modified the Makefile as the one attached to this email.
i also modified the release file under configure to include the different variable path.
i modified my st.cmd file as well to include the ip port configuration as attached as well.

my problem is this, when a run make under this directory, xxxApp/src it create two file, the application executable and the sncExample executable but never an ipSNCServer executable. when i run the st.cmd i get this output.

cas warning: Configured TCP port was unavailable.
cas warning: Using dynamically assigned TCP port 53146,
cas warning: but now two or more servers share the same UDP port.
cas warning: Depending on your IP kernel this server may not be

Thank for any assistance.
