When adding a expansion chassis to the DDP or when our team ask for direct access to a DDP for advanced diagnostics, initiating service connection becomes necessary.
Service connection consists in a remote access program that is included in every DDP.
The only requirement for initiating service connection is that the DDP has access to the internet.
During the connection, a secure shell tunnel is set up via port 22 outgoing and connects to a fixed modem address at Ardis Technologies.
If the customer believes that is not safe enough, the customer and Ardis Technologies will cooperate to setup up a remote connection which is approved by the customer.
Because service connection (or VPN) is mandatory for support, the DDP second NIC is set to DHCP by default.
Service connection provides a direct access to the DDP using an internet connection. The NIC 2 of each DDP is dedicated to that purpose, so you first need to locate it on the DDP and connect it to the internet.
The NIC 2 can be found at the back of the DDP, next to the USB and VGA ports of the motherboard.
It is the second ethernet port from the left as show in the following picture:
The NIC 2 should be reachable by the DHCP server. You can make sure an DHCP lease could be obtained by checking the IP address assigned for eth1 in the “network” page inside the DDP web GUI.
If you cannot see any IP address, press the “Get DHCP lease” button.
The current settings should show now get a proper IP address for eth1, as well as a subnet mask, DNS server and gateway address.
If you don't have any DHCP server available, you can also use a fixed IP address for eth1, however in that case, you might need to put the gateway IP address in the "Gateway" page.
Please make sure that the port 22 outgoing (ssh port) is open on the gateway, modem or fire-wall.
You can then check your internet connection by connecting to the DDP by ssh (user: root password: aap) and entering the following command:
$ ping 8.8.8.8
After you made sure the DDP can reach the internet, you can finally initiate the service connection by entering the following command:
$ connect-to-internet
Warning: As Ardis IP address changed in 2015, for all OS version prior to v3.00.019 you will need to enter the following command instead of the usual “connect-to-internet” command:
$ ssh -N -R 2222:localhost:22 forward@178.132.208.117 -f
From v3.00.019 version, the IP address is already updated so you can enter the usual connect-to-internet command.
The first time you enter that command and if your internet access is properly configured, you will be asked whether you want to continue connection or not, please enter ‘yes’ as below to start the service connection:
If you get a message like “Connection timed out”, please then contact our team.
