I don't have a Mac. Run a simple java program on your Mac --
Note that AFAIK the code is > 3 years old and has been tested constantly
-- every start-domain exercises it. Every asadmin command runs this
code too.
------------------------------------
import java.net.InetAddress;
import java.net.UnknownHostException;
import java.util.*;
import java.util.logging.Level;
import java.util.logging.Logger;
public class Main {
public static void main(String[] args) {
try {
System.out.println(getCanonicalHostName());
}
catch (Exception ex) {
}
}
public static String getCanonicalHostName() throws UnknownHostException {
InetAddress localhost = InetAddress.getLocalHost();
String defaultHostname = localhost.getHostName();
String hostname = localhost.getCanonicalHostName();
String hostaddress = localhost.getHostAddress();
// check to see if ip returned or canonical hostname is
different than hostname
// It is possible for dhcp connected computers to have an
erroneous name returned
// that is created by the dhcp server. If that happens, return
just the default hostname
if (hostname.equals(hostaddress) ||
!hostname.startsWith(defaultHostname)) {
// don't want IP or canonical hostname, this will cause a
lot of problems for dhcp users
// get just plan host name instead
hostname = defaultHostname;
}
return hostname;
}
