<br>
<br>
<br><font size=2 face="sans-serif">That is no node is connected to it....</font>
<br>
<br><font size=2 face="sans-serif">Now the point is C node has successfully
connected ....</font>
<br>
<br><font size=2 face="sans-serif">Why Erlang node is not showing it as
connected....</font>
<br>
<br><font size=2 face="sans-serif">Do we need to register the C node with
EPMD even when it is acting as a client...</font>
<br>
<br><font size=2 face="sans-serif">Do we need to register Erlang node with
EPMD as well and if yes the how do we do that..</font>
<br>
<br><font size=2 face="sans-serif">Note : I am using putty to connect to
single linux server (FC8).</font>

<br><font size=2 face="sans-serif">Appreciate your help...</font>
