# 1
wget http://supergsego.com/apache/tomcat/tomcat-8/v8.5.4/bin/apache-tomcat-8.5.4.tar.gz

vim conf/server.xml
# look for: <Server port="8005" shutdown="SHUTDOWN">
# and add as children:
<Listener className="org.apache.catalina.mbeans.JmxRemoteLifecycleListener" rmiRegistryPortPlatform="10001" rmiServerPortPlatform="10002" />

# in your box create a tunnel
ssh -f userssh@bastion.env.com -L 10001:ec2-1-1-1-1.us-west-2.compute.amazonaws.com:10001 -L 10002:ec2-1-1-1-1.us-west-2.compute.amazonaws.com:10002 -N
