weirds traces

Dear all,

I am trying to connect to a socket at 20002 port where an application
is listening to.

I am using ethereal to sniff what is going back and forth to that
server. From one linux box it takes 5 secs to receive and ACK and from
another one only 1 sec. The latter behaviour is the normal from any box
(Windows & linux) I have tried. I issued a telnet from both linux boxes
and both get the ACK but the traces are a bit different. Mainly I
realised that I keep on getting the following two traces:

1623.286532 10.95.84.67 -> 10.95.84.68 NBNS Name query NBSTAT
*<00><00><00><00><00><00><00><00><00><00><00><00><00><00><00>
1623.286563 10.95.84.68 -> 10.95.84.67 ICMP Destination unreachable

Anyone can shed any light on this?

Regards

Miguel
