You have to use getLocalHost() on a connected Socket, not on InetAddress to
get the local address of the socket.

Yes, it works now! Thanks.

Could anybody think of negative implications of doing this reverse ordering of 
the localhost and ip address entries?

Local IP address / Java Incompatibility

1998-10-12 Thread Rainer Dorsch 
We found an incompatibility between Java on Solaris 2.5.1/2.6 and on Debian 
2.0.r2 Could anybody suggest how to find out, if it is a bug in Debian Linux 
or JDK?

Additions to the included bug report:

- $ hostname -i
  129.69.183.3

  gives the correct answer in a shell.

- Debian 2.0 comes with jdk-1.1.5v5-1


Thanks.

Hello!

I have tried to get the IP address and host name of the host running my 
Java application using the following Java-Code:

  InetAddress inetadr = InetAddress.getLocalHost();
  System.out.println("LocalIP:   " + inetadr.getHostAddress());
  System.out.println("LocalName: " + inetadr.getHostName());

This works well for a SUN system, but I always get 127.0.0.1 and
localhost on my Debian Linux system. Is this a bug in Linux-Java or
is there any other way to determine the name and IP address of my
localhost???

Can anyone help me?

bye Thomas!
