iface lo inet loopback
iface eth0 inet static

After you saved this file, run this
Also check that in your /etc/resolv.conf file you have the correct nameserver:
This should get your network online (until you reboot, since the actual settings are in the datbase).
To allow me access into the system you have to enable Remote Assistance. There are two ways to do this:
1. from the Pluto Admin website, go to Wizard -> Security -> Outside access, tick the "Allow Pluto tech support temporary access using this password" checkbox, write the password twice and click Update
2. from the console, run /usr/pluto/bin/RA.sh and follow the instructions
After you enabled this, send me your installation number and the password you wrote in there to this address: radu.c _at_ plutohome.com
Tell me if the system is going to be online all the time, or just in a certain hour interval so I can sync.
