After some more debugging... 1. In fact they should be interoperable. If UNIX socket fails, ti-rpc library tries backwards-compatible method (IP socket on localhost). 2. For some reason it tries IPv6 socket, and, of course, fails. It doesn't try IPv4 after this. 3. If i comment out IPv6 entries in /etc/netconfig, it will try IPv4 TCP socket. But for some weird reason it fails to connect() with EADDRINUSE error. 4. rpcbind is not part of ti-rpc library. I was confused by man file with this name. I read about this problem, but i don't really understand this SO_REUSEADDR trick. So i decided not to modify the tirpc code, assuming it works, and it's some WinSock-specific glitch. Instead i quickly ported rpcbind (http://sourceforge.net/projects/rpcbind/), and the whole thing runs correctly now. -- Kind regards Pavel Fedin Expert engineer, Samsung Moscow research center -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
