 From a send I posted to advanced-java mailing list:

Hello,

I've done the background work on this and didnt find very much that
applied. I have two machines both of which are Solaris 2.5.1 machines.
Specific architecture is as follows:
  SunOS pandora 5.5.1 Genric_103640-08 sun4u SUNW,Ultra-Enterprise

One of these machines is dual-homed with two lance interfaces.
The other machine is single homed with a fiber interface.

Lastly, I speculate they are both using some form of DHCP boot.

InetAddress.getLocalHost() under JDK 1.1.3 is returning the address for
localhost/127.0.0.1. This is what is returned by
java.net.InetAddressImpl as provided. One of the threads I read
indicated that this information was gathered from sysinfo, however
initial tests do not seem to confirm that. This simple application
returned the name pandora.

  #include <stdio.h>
  #include <stdlib.h>
  #include <sys/systeminfo.h>

  void main() {
    char host[512] ;
    sysinfo( SI_HOSTNAME, host, sizeof(host) ) ;
    printf( "%s\n", host ) ;
  }

Is anyone familiar enough with the workings of InetAddressImpl on
Solaris to tell me what might be causing this to occur.

-- Additionally, source code which causes the failure

import java.net.* ;

public class test {
  public static void main( String[] args ) throws Exception {
    InetAddress addr = InetAddress.getLocalHost() ;
    System.out.println( addr.toString() ) ;
    System.out.println( addr.getHostName() ) ;
    System.out.println( addr.getHostAddress() ) ;
  }
}

-- Results

localhost/127.0.0.1
localhost
127.0.0.1

-- Further information, output from ifconfig
