RE: ORBit without DNS?

Hi

This is my ior-decode output:

--------------------------------------
Tags known:
TAG_INTERNET_IOP: 0x0
TAG_MULTIPLE_COMPONENTS: 0x1
TAG_ORBIT_SPECIFIC: 0xbadfaeca

Object ID: IDL:Name/NameServer:1.0
Profile count: 2

Profile type: TAG_ORBIT_SPECIFIC
Object endian: Little
IIOP version: 1.0
Socket path: /tmp/orbit-root/orb-19846032311201307366
IPv6 port: 0
Object key: ".....,.....n.......2.n.<"

Profile type: TAG_INTERNET_IOP
Object endian: Little
IIOP version: 1.0
Host: 200.2.1.40
Port: 1028
Object key: ".....,.....n.......2.n.<"
-----------------------------------------------------------

However, I think this is the problem:
src/IIOP/connection.c - iiop_connection_server() uses gethostname() &
gethostbyname() to get the host details. If hostname contains a '.' then
the hostname is used as it is. Otherwise gethostbyname() is called to get
the IP Address.

This is the code snippet from connection.c:
....
gethostname(hn_tmp, sizeof(hn_tmp) - 1);
  hent = gethostbyname(hn_tmp);
  if(hent)
    {
      if (strchr (hent->h_name, '.'))
  server_cnx->u.ipv4.hostname = g_strdup(hent->h_name);
      else
  {
    struct in_addr * addr = (struct in_addr *) hent->h_addr_list[0];
    g_assert (hent->h_length == sizeof (struct in_addr) && addr);
    server_cnx->u.ipv4.hostname = g_strdup (inet_ntoa (*addr));
  }
    }
  else
    server_cnx->u.ipv4.hostname = g_strdup(hn_tmp);
....


Try to rename your official hostname to be w/o a '.'. Eg change your
/etc/hosts as <IP Address> testhost, if you are using /etc/hosts. Run your
server again & run ior-decode on the ior file.
I just went through the source code & found out this. Other people on the
list may be able to throw more light.
