Thanks to everybody who responded. I have now coabs working properly. I had eth0 running multicast but not lo so I did
ifconfig lo multicast route add -net 224.0.0.0 netmask 240.0.0.0 dev lo and I got the lookup services up. I am getting a strange message though from jini and I wonder if you've encountered that: java.io.IOException: port number out of range: -2097938432 at net.jini.discovery.IncomingMulticastAnnouncement.<init>(IncomingMulticastAnnouncement.java:83) TIA myriam ---------------------------------------------------------------------- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
