[omniORB] Problem in network between 'server' and 'client'

[VEYSSIERE Nicolas]

Good news, I managed to find the problem :

in the file src/lib/omniORB/orbcore/tcp/tcpAdress.cc, in the doConnect method, and in the USE_NONBLOCKING_CONNECT block, the call to connect have to be patched.

It seems there is a bug in connect in HP-UX 11.23 (I have to contact HP for that).

The bug : connect return -1 (RC_SOCKET_ERROR) but, errno = 0 !

So I here is the new code :

  if (::connect(sock,ai->addr(),ai->addrSize()) == RC_SOCKET_ERROR) {

    if (ERRNO != EINPROGRESS
#if defined(__hpux__)
    	    && ERRNO != 0
#endif
    ) {
      logFailure("Failed to connect", ai);
      CLOSESOCKET(sock);
      return 0;
    }


Houra ! it works !


Thanks for all.

Yes, I tried to find a firewall problem, but when in the logs it fails to open ip/port connection, I tried to open a telnet to this ip/port and nothing is blocked, but as I am send bad data, there is an exception fired in the client.


This seems to be a HP-UX configuration problem.


As soon I find it, I will post it here.

It is presumably due to the difference between which end opens the
network connection. There could, for example, be a firewall that allows
outgoing TCP connections on arbitrary ports, but does not permit
incoming connections.

Cheers,

Duncan.
