Hello Mikolaj, I have set up the JMX server of JDK 1.5.0_06/Tomcat 5.5.15. It works fine locally, I'm testing with jconsole. However, if I tunnel the JMX port over SSH, it does not work. I can connect to the port, but there is no flow of data. jconsole is hanging around for a minute, and then the connect dialog pops up.

Re: JMX via SSH tunnel does not work?
We had issues using jconsole remotely a while back (jdk 1.5.0_02) that we were never able to solve. If memory serves, jconsole opens a connection on the specified port to that Java instance. An additional port or two (I can't remember) are then opened and the ports that are used are somewhat random making it very difficult to do this through anything that needs to port forward or needs ports opened. I do not remember if the additional ports are opened by jconsole or the other way, but you can see it by connecting locally and checking netstat for connections to/from the jconsole process. The only solution here is to be able to specify the additional ports, but at the time there was no way to do this. I have not looked into the jconsole or JMX options since so I do not know if this was added.
