Remote Support for OpenERP on a server without Public IP....

         Most of us will be connected to Internet either through dailup or
  broadband connection provided by service providers or from the LAN network hidden
 from outside world.In both the cases system make use of either dynamic IP provided by the
 service provider which may change each time newly connected or network private ip which
 cannot be used or not visible to outside world.Now question is how can we access such
 system and make use of the services running on that system.
 

            Consider the situation that you were working In OpenERP at home with your PC or laptop connected
to a Internet through modem. Now you might need to access local OpenERP from your office or work location
for any reference. Reverse SSH tunneling, the process forwards the local machine service to a remote machine
in a secure way helps us here.

              Now at the home pc,to make it accessible from office later you can type at the command line,
                   sudo nohup ssh -f -N -R 8070:localhost:45678 root@<Your Office Public IP>
                               here,
                                        8070  is the netrpc port of OpenERP running at home
                                       45678   is the remote port on server 
                                      <Office Public IP> Contact your system administrator for Public IP and root password
                       
                         Note : Make sure there are no services running on remote office server port going to be used
                                   for tunneling purpose.you can also use web interface remotely instead of 8070 change it
                                  into 8080 local web running port.

              At Office You can acces OpenERP running at home by using the public IP  and port 45678 to which
              you have forwarded.

              It is also possible to login into your system at home by issuing the following command,you will 
              get shell interface as if you were working at home,from your office
                    

                    sudo nohup ssh -f -N -R 22:localhost:45679 root@<Your Office Public IP>
                            
               You can login into local home mcahine from any where by using,
                    ssh root@<Your Office Public IP> -p 45679

            Same can be applied  for machine inside LAN network which uses NAT service to get connected 
to Internet.Similarily Support service can be provided for OpenERP in your system even though you don't
have public ip.Thinking that this blog might had helped you.....
