Ok I am back on this problem. Normally, it seems, jboss uses port 1099 for this shutdown process. The instance I am trying to shutdown is 1199 so I have tried the following: (Keep in mind JBOSS runs as jboss user from one directory, and the instance resides in user1's directory and is started as that user1) Try 1: $JBOSS_HOME/bin/shutdown.sh -s localhost:1199 Error: Failed to authenticate principal=null, securityDomain=jmx-console Try 2: $JBOSS_HOME/bin/shutdown.sh jnp://localhost:1199 Error: same as above plus: Failed to connect to server localhost:1099 So Try 2 it shows its still looking for port 1099 which isnt even running.
