[omniORB] HPUX unable to create an endpoint

[Joe Lee]

We are also seeing an issue on HPUX 11.11 with omniORB 4.1.1 where
running the sample echo program eg2_impl gives:

omniORB: Error: Unable to create an endpoint of this description:
giop:tcp::0

Caught CORBA::INITIALIZE



This is on a system that isn't on an IPv6 network.



So we can get it to work when we run with -ORBendPoint giop:tcp:0.0.0.0:

It also works if we configure omniORB with -disable-ipv6.



Just wondering if there is anything we can do to make it work without
the above workarounds.



Thanks.



-Joe

This is on a system that isn't on an IPv6 network.

When you don't specify an explicit address, omniORB first calls
getaddrinfo() with a family of PF_UNSPEC and flags AI_PASSIVE, to get
the protocol family and socket address it should use. Then it uses the
family as an argument to socket(), followed by a call to bind() giving
the socket and the address return by getaddrinfo(). If any of those
things fail, you will get the error you see.

The first stage to track it down is to instrument
src/lib/omniORB/orbcore/tcp/tcpEndpoint.cc, in the Bind() method, to log
at what stage the failure occurs. That will narrow down what it is that
HPUX doesn't like.

Cheers,

Duncan.
