How to build a replicated ehcache through firewall and not to die trying
It's assumed that:
The problem here is that these random ports are not accesible to remote hosts because the hosts are behind a firewall.
So to fix it, we need to configure ehcache to only use 2 ports. The "remoteObjectPort" does the magic. So we have this ehcache.xml configuration:
Open the 4 tunnels to the remote machine:
Run java programs on both machines (local and remote) with the "java.rmi.server.hostname" so the RMI server reports to the other RMI (the remote one) that it's address is "127.0.0.1" rather than any other IP it may has; so the tunnels can work. If you have any comment or suggestion please contact me.
- You already have a java application and you have an ehcache instance running in your program with 1 cache configured to replicate.
- You want to connect 1 instance to another instance you have in a remote machine
- The remote machine you are connecting to is located behind a firewall.
- You have been given access to only 1 port to make an ssh connection to the remote (firewalled) machine.
The problem here is that these random ports are not accesible to remote hosts because the hosts are behind a firewall.
So to fix it, we need to configure ehcache to only use 2 ports. The "remoteObjectPort" does the magic. So we have this ehcache.xml configuration:
- 1 server port for the ehcache server to listen to other ehcache servers.
- 1 server port for the ehcache cache to listen to incoming connections (this cache is the actual map in memory that is being replicated).
Open the 4 tunnels to the remote machine:
- 1 local port for the ehcache server to listen to incoming connections from remote cache server
- 1 local port for the ehcache cache for incoming connections from the remote cache
- 1 remote port for remote ehcache server to listen incoming connections from our local host
- 1 remote port for remote ehcache cache to listen to incoming connections from our local host
Run java programs on both machines (local and remote) with the "java.rmi.server.hostname" so the RMI server reports to the other RMI (the remote one) that it's address is "127.0.0.1" rather than any other IP it may has; so the tunnels can work.

A healthy alternative is for you to Buy Home Gym Equipments that you can store in your own home or even at your office. Here are some tips when buying home gym equipment.

One of the biggest mistakes that people make is buying the biggest or trendiest fitness machine simply because they like how it looks. More often than not, these end up gathering dust in your storage rooms or garage because you never end up using them. It is important to take note of what particular type of physical activity you want or enjoy doing before you buy your exercise machine. If you are looking to loose a few pounds and you enjoy walking or hiking, a treadmill is the best option for you. If you are looking to tone your lower body while burning calories a stationary bike is your obvious choice. Similarly, Special Equipments for Core Strength Exercises, Strength Training Weight Vests, Core Strength & Abdominal Trainers, Home Cardio Training, Strength Training Power Cages, Strength Training Racks & More.
Second, set aside a budget before Buying Home Gym Equipments. Quality exercise machines do not come cheap. They are constantly exposed to wear and tear when they are used properly. So, pick machines that are built to last and have passed quality certifications to get the most out of your money. If you are operating on a tight budget, think about investing in several weights, We can Provide you High Quality Home Gym Equipments at Very Low Prices for your Complete Uses: Core Strength Exercises, Strength Training Weight Vests, Core Strength & Abdominal Trainers, Home Cardio Training, Strength Training Power Cages, Strength Training Racks & More.
