I installed on my Ubuntu 12.10 open ssh server and I'm trying to configure to access it from anywhere. The problem is that I'm on a local network and all the computers surf on the internet with the same IP address. Our internal addresses are like 10.4.x.x and we "go out" with this IP address : 141.x.x.x.

My question is : If I want to remote ssh my laptop how can I reach my machine?

P.s. : I forgot to mention that our local IP addresses are changing at every re-connect.

You'll need to check your router for port forwarding and hopefully you can assign a static IP for the server (and hardwiring it is best practice for servers). You would then ssh to your house and your router would detect port 22 (unless you specify another) and forward it to the server's IP to handle it. –  nerdwaller Apr 22 '13 at 1:13
    
i don`t have acces to the router. that`s the problem ! :) –  Matei Apr 22 '13 at 9:02
    
Something like a reverse ssh tunnel may be necessary then... –  nerdwaller Apr 22 '13 at 13:51
