Hi,

    thanks for this way.
    I hastly changed my config to integrate a listener write in Perl but I
encounter a pb with config in "jabber.xml".

<service id="sniffer">
    <host>myserver</host>
    <host>sniffer.myserver</host>
    <accept>
        <ip/>
        <port>myport</port>
        <secret>secret</secret>
    </accept>
</service>

when I set <host>myserver</host>  I get an error during user's connection :
20020812T16:28:59: [notice] (myserver): bouncing a routed packet to
myuser at myserver from 20 at c2s/8105460:
Unable to deliver, destination unknown

when I set <host>localhost</host> and <host>sniffer.localhost</host> all work
fine, but "sniffer" don't receive fragment. It see them only when "to"  JID is
"... at localhost".
<service id="sniffer">
    <host>localhost</host>
    <host>sniffer.localhost</host>
    <accept>
        <ip/>
        <port>myport</port>
        <secret>secret</secret>
    </accept>
</service>

I don't understand where is the mistake...
Any help?
