bookmark_borderAccessing a FreeNAS Jail via SSH-Tunnel

Posted on by dansku

If you ever need to remotely access an application running inside a FreeNAS jail, you can create an SSH Tunnel to the server and map the local IP Address and port of the jail with

ssh -L JAIL-PORT:JAIL-IP:LOCAL-PORT user@host

As an example, let’s say you can access your FreeNAS server via ssh with user@domain.com, the jail IP is 192.168.1.10 and it is running an application on port 8080.

To create the tunnel, you would use

ssh -L 8080:192.168.1.10:8080 user@domain.com

Once the tunnel is up and running, you can access the service locally with localhost:8080 🎉

Dropbox is a great software that I have been using for almost 10 years. It has helped me a lot during university, sharing project files, backing up my thesis and much more. It is a great service, but it also comes with a lot of problems regarding security and transparency (I will not get in-depth here). You can check for example, this article, or this one (there are many more if you look for it).

With this security issue in my mind, I decided to roll my own Dropbox-like service. The main difference is that I will know where all files are and that I am the only one with access to the unencrypted files. After building my own simple infrastructure, I decided to write a quick tutorial showing my solution and how you can create your own! Let’s get started…

The main software that we are going to use is called Resilio Sync (previously BitTorrent Sync). It takes care of all the syncronization between computer, mobile and server, just like Dropbox.
