Jmx And Firewalls Or How To Hate Rmi Slightly Less

by Mike Wallis ~1 min read

So at least with Java 1.6 the JVM can use SOCKS for proxying RMI requests, so to get the wonderful jvisualvm (think 1.5 visualGC) working use the following incantations. This requires the initial RMI registry port is open to the client. First the initial SSH to server enabling the SOCKS tunnel

$ ssh -D localhost:9696 servername

And now for jvisualvm:

$ jvisualvm \
  -J-Dnetbeans.system_socks_proxy=localhost:9696 \
  -J-Djava.net.useSystemProxies=true

props to Stackoverflow for the hints
