[JDEV] server to server

[Alex She<Wizdomtech - Analyst Programmer>]

I do not know if this is right place for this question.
I want to test server to server connection , I run two jabber servers, One 
listen to port 5269 as following :
<service id="s2s">
    <load>
      <dialback>./dialback/dialback.so</dialback>
    </load>
    <dialback xmlns='jabber:config:dialback'>
      <legacy/>
      <ip port="5269"/>
      <karma>
        <init>50</init>
        <max>50</max>
        <inc>4</inc>
        <dec>1</dec>
        <penalty>-5</penalty>
        <restore>50</restore>
      </karma>
    </dialback>
  </service>
the other add a base connect service as following:
 <service id ="base_connect">
      <connect>
       <ip>192.168.90.117</ip>
	    <port>5269</port>
	    <secret>aaa</secret> <!-- what about secrect tag -->
	    <timeout>5</timeout>
       <tries>15</tries>
     </connect>
   </service>
but can not connect server, and print error message "[mio]unlink socket from 
client", and listening servere print 
"20011031T02:41:14: [notice] (update.jabber.org): timed out from dnsrv queue
20011031T02:41:14: [notice] (update.jabber.org): bouncing a packet to 
jsm at update.jabber.org/1.4.1 from htgzln117.htgz.com: Hostname
Resolution Timeout"
Questions:
1. how to make a server to server connection?
2. base_connect module can do this?
3. why listening server report dnsrv timeout ? I can $ping htgzln117.htgz.com 
in shell.
thanks in advance.
