[jboss-user] three dynamic tcp ports

[Donghui Wen]

Hi,
   On my jboss-4.2.1.ga server, I always found that there are three
   dynamic ports are listening, they are bind to all ip addresses, even
   I start jboss with "-b 127.0.0.1", I can still see those ports:

lsof -p 393 | grep LISTE

java    393 pnadmin  118u  IPv6     285300              TCP
localhost:8083 (LISTEN)
java    393 pnadmin  120u  IPv6     285304              TCP
localhost:1099 (LISTEN)
java    393 pnadmin  121u  IPv6     285302              TCP
localhost:1098 (LISTEN)
java    393 pnadmin  122u  IPv6     285306              TCP *:34929
(LISTEN)
java    393 pnadmin  125u  IPv6     285308              TCP *:34930
(LISTEN)
java    393 pnadmin  126u  IPv6     285315              TCP *:34932
(LISTEN)
java    393 pnadmin  128u  IPv6     285318              TCP
localhost:krb524 (LISTEN)
java    393 pnadmin  129u  IPv6     285320              TCP
localhost:4445 (LISTEN)
java    393 pnadmin  130u  IPv6     285321              TCP
localhost:4446 (LISTEN)
java    393 pnadmin  135u  IPv6     285335              TCP
localhost:3873 (LISTEN)
java    393 pnadmin  152u  IPv6     285454              TCP
localhost:webcache (LISTEN)
java    393 pnadmin  153u  IPv6     285455              TCP
localhost:8009 (LISTEN)
java    393 pnadmin  155u  IPv6     285457              TCP
localhost:8443 (LISTEN)
java    393 pnadmin  156u  IPv6     285458              TCP
localhost:8444 (LISTEN)
java    393 pnadmin  185u  IPv6     285565              TCP
localhost:8093 (LISTEN)

Does anyone know how to what are these ports (34929,34930,34931)? Is it
possible to make it bind to fixed port?

Thanks,
Donghui
