Identify Java jdwp Debugger Assigned (Ephemeral) Port

Question

I am using the following JVM parameters to start-up a JVM with the hostpot debugger.

-Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=0

Answer 1

Maybe something you could start with.

netstat -tlnp

This gives you a list of all processes listening on a local TCP port. For example:

tcp    0    0 0.0.0.0:35688     0.0.0.0:*     LISTEN   26733/java

35688 - the ephemeral port
java  - the program name which is listening
26733 - the PID of the process 

If you need a finer granularity of the java processes you could use ps to gather informations about the process.

ps x -p 26733

could return something like

26733 pts/1 0:00 java -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=0 Scratch
