Hi All, I posted several weeks ago about an issue that a client failed to connect local server on vxWorks 6.3. We developed a PCAS server and a client based on libcas and libca (EPICS Base 3.14.9). They work well on Windows, and we are now porting them to vxWorks (ppc-603). During the process, we found the issue that, if the client and server are on a single host, the connection couldn't be established. After debugging for a long while, we found the root issue is that a broadcast to 255.255.255.255 from a vxWorks host CANNOT be heard by local host. It seems like a loopback policy limitation for vxWorks. So I'd like to know if there's anyone who ran into the same issue as I am. Or someone who can successfully connect a client to a local server on vxWorks, and how do you do that. Thank you very much for your time.
