Question/Problem Description

How to retrieve the local IP address on client side within an interceptor?

Clarifying Information

Orbix provides the following methods to access the local and remote address:

local_address_literal() returns the local address, in string format, of the GIOP connection over which a request was received.

remote_address_literal() returns the remote address, in string format, of the GIOP connection over which a request was received.

Both of the above APIs are server side only, so using these from a client side (withing send_request) is not expected to work.

Resolution

Accessing the local address on the client-side, e.g. in an interceptor can be achieved by using the following code:

CORBA::Object_var obj = orb->resolve_initial_references("IT_IPTransport");

if (CORBA::is_nil(obj))
{
    self_addr = (const char*) 0;
    return;
}

IT_ATLI2_IP::IPTransport_ptr ip_transport = IT_ATLI2_IP::IPTransport::_narrow(obj);

if (CORBA::is_nil(ip_transport))
{
    self_addr = (const char*) 0;
    return;
}

CORBA::String_var hostname = ip_transport->local_node_name();

IT_ATLI2_IP::IPAddressSeq_var ip_addresses =
    ip_transport->name_to_addresses(
        hostname,
        0,
        IT_ATLI2_IP::PROTOCOL_TCP,
        IT_UtcT::never()
    );

IT_ATLI2_IP::IPAddress_var ip_address = ip_addresses[0];
self_addr = ip_address->node_literal();
