FULL PRODUCT VERSION :
java version "1.5.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-b64)
Java HotSpot(TM) Client VM (build 1.5.0-b64, mixed mode)
JDK 1.5.0
JDK 1.6.0-EA
ADDITIONAL OS VERSION INFORMATION :
Fedora Core 3 2.6.9-667
Debian testing 2.6.8-1
Debian unstable 2.6.9-1
SUSE ENTERPRISE LINUX 9
Windows XP SP 1
A DESCRIPTION OF THE PROBLEM :
jconsole won't connect to a remote Linux JVM - "connection failed". Tested on different Linux distributions and versions, and on different JVMs.
I can connect just fine locally on all Linux platforms, using either Local or Remote tab in jconsole.
I can also connect remotely from Linux to JVM on Windows XP, using the same command line and SampleTest.
Connecting from Linux to Linux or from Windows to Linux does NOT work, however.
I'm not running firewalls or filters on any of these systems. Network is working, cause I'm using ssh/scp/ftp to login and copy files etc. ping between these systems work. I can also connect using telnet remote-ip 8999 from the jconsole box to the remote JVM and see that it actually responds (pressing Enter three times closes the connection).
I'm having the same problem for authenticated (still no ssl) connection. This also means that authenticated works *locally*, just not remotely.
On the "server" side, I'm using the JMX SampleTest program.
(Haven't found anything in the installation notes or release notes indicating this should not work on Linux. Also, haven't found anything in Bug Parade, on java.net/java.sun.com forums or Google.)
STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
On the "server" side:
java -Dcom.sun.management.jmxremote.port=8999 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false SampleTest
(used -Dcom.sun.management.jmxremote only to test Local-only connection.)
On the client side:
jconsole remote-ip:8999
EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Connect!
ACTUAL -
jconsole reports "Connection failed".
ERROR MESSAGES/STACK TRACES THAT OCCUR :
jconsole reports "Connection failed".
REPRODUCIBILITY :
This bug can be reproduced often.
