"Operation not permitted" during startup

objectinc Mar 16, 2006 4:06 AM

Hi,

I dicovered a strange behaviour of jboss on SuSe linux 9.2. All I did was extracting the jboss to the desired folder and start the run.sh.
But the startup doesnt went fine.
During startup I get the following message, more times than I'm able to count ;-):
22:52:47,448 ERROR [UDP] exception=java.io.IOException: Operation not permitted, msg=[dst: 228.1.2.3:45551, src: hamburg132:36017 (2 headers), size = 0 bytes], mcast_addr=228.1.2.3:45551

On my other linux boxes the startup went fine. I ran out of ideas.

Please help me!

Thanks in advance.

Andreas

Most likely multicast is not enabled.

Maybe this is a stupid question. But in all my years of java development I've never had this problem. So how to enable mutlicast? Till now this wasn't necessary.

And in all your years, how many times have you seen this exception? Clearly some network/hostname configuration exists on this box. Check out your os howtos/faqs for enabling multicast.
