JMX password read access issue

Question

When I try to use JMX to monitor an application like this:

java -Dcom.sun.management.jmxremote.port=9999 \
     -Dcom.sun.management.jmxremote.authenticate=false \
     -Dcom.sun.management.jmxremote.ssl=false \
     JMX_tester

it tells me:

Error: Password file read access must be restricted:
       /usr/lib/jvm/java-7-oracle/jre/lib/management/jmxremote.password

Yet, when I use chmod to restrict the read access, it tells me:

Error: can't read password file

Am I going insane or something? How can I fix this?

This is Ubuntu btw, with the latest oracle jdk

Same issue for me on Windows. – RobertG Mar 21 '14 at 09:52 — RobertG, Mar 21 '14 at 09:52

Make sure the user you are using to run the java process have access to the file (owner/read permissions).

Try:

chmod 600 jmxremote.password

Plus I suggest you'll make your own password file and run it with

-Dcom.sun.management.jmxremote.password.file=pwFilePath

All explained here.

But when authenticate=false is set why we need password ...? – Kanagavelu Sugumar Nov 22 '17 at 18:33
@KanagaveluSugumar Check your property spelling, possible overrides, etc. in your configuration. It tends to be error prone. However, the `authenticate=false` really disables the password checks. – Yuri Dec 11 '17 at 09:37

@Radioactive to what question are you referring? – Elad Tabak Nov 21 '18 at 15:04
@EladTabak I was also getting the same issue inspite of having set the "-Dcom.sun.management.jmxremote.authenticate=": "false". So I my question was if it is set to false why is it looking for the password folder. – Radioactive Nov 27 '18 at 02:16

If you want to bypass authentication try to use below parameters.

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.authenticate=false
-Dcom.sun.management.jmxremote.port=port
-Dcom.sun.management.jmxremote.ssl=false
