remote jconsole connection did not succeed
Hi *,
in this setup there are two tomcat 6.0.18 instances each running on
separate windows 2003 server with Sun JDK 1.6.0_12.
I have configured JMX console access pretty much the standard way on
both systems, with switches:
-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.port=9004
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
The funny thing is that I can connect to one Tomcat both locally and
remotely, but only locally to other Tomcat instance (that is, from the
same system and to local process).
If I try to connect remotely to that instance, connection fails with
message "the connection did not succeed".
I dont even have a clue what to look for :(
Both servers are nearly identical and run the same webapps.
Thanks for your time,
Ivars

Well, could it be anything else because firewall is turned off on that
server?

This is usually the firewall blocking the secondary (and unpredictable) JMX port. See the discussion here:
http://marc.info/?l=tomcat-user&m=122277270626801&w=2
If you can't turn off the firewall, the enhancement should be available in the next Tomcat 6.0 release, or you could just pick it up from svn and build it in.

nope, I can connect just fine:
ivarss@poga:~$ telnet hostname 9004
Trying 192.168.0.3...
Connected to hostname.domain
Escape character is '^]'.
