Re: AWT Crash - Need Help!
this is due to x server configuration problems. though it may be working fine with normal x apps you need to do some 'fine tuning' in it.

change com.sun.java.swing.JApplet into javax.swing.JApplet

At least the DNS admin at my previous job claimed this was so. > If you give each interface a DNS entry, each name must be unique. With 4.9.3 it became possible to specify several A records for a given DNS name. We were doing that for load balancing at my previous place. See the following extract from DNS-HOWTO: 3. How do I make DNS rotate through the available addresses for a service, say www.busy.site to obtain a load balancing effect, or similar? Make several A records for www.busy.site and use bind 4.9.3 or later. Then bind will round-robin the answers. It will not work with earlier versions of bind. > > Even if you have an internal DNS with one address, and an external DNS with > a different address, when your own host looks itself it, it can only get > one A record back. > > So, if what I understand of DNS is true, it is just that easy. > > I think for all practical purposes the value returned by getInetAddress() will be sufficient. A computer will be having n number of interfaces and all of them need not be in the DNS record (or hosts file). But the program at the other end will be able to know through which interface the connection is being made. So in the worst case one can think about retrieving the IP of "this side" from that program ;-) Anil -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
