SummaryAn Exinda can automatically 'phone home' and contact the licensing servers to routinely check for updated licenses that might have been generated for the unit.This prevents the need for manual input of a new license key.
OverviewAny Exinda appliance has the ability to contact the Exinda Licensing Server built into the firmware. This automatic check can be done on a schedule as long as everything is set up properly on the Exinda. The Exinda uses the management port (most likely eth1, depending on the model) to conduct this check, so eth1 needs to be fully configured to access the outside world. This can be accomplished through 2 methods:
- Ensuring DHCP is set for the management port
- Statically configuring the management port
To Contact the License server, the following information is needed (whether it is supplied manually or by DHCP):
- Management IP address (Configuration > System > Network, the "IP Address" tab)
- Default gateway (Configuration > System > Network, the "IP Address" tab)
- DNS Servers (Configuration > System > Network, the "DNS" tab)
If you get a response of "Connection Failed. Check Network Settings", it means that there is a problem with the the connection between the Exinda and the licensing server. If this occurs, double check to ensure that there is an IP associated with the management port, there are name servers populated in the list on the DNS tab, and whether there is a default route set up under Configuration > System > Network, the "Routes" tab; this should be using your default gateway. If one of these three parameters are not set, the connection will not work.
If those parameters are set and the error is still seen, try the following troubleshooting:
- Configuration > System > Tools, under the "DNS Lookup" tab, do a lookup for license.exinda.com. If a response is not obtained, the DNS servers set up on the box cannot resolve that name to an IP; try adding different DNS servers statically
- Configuration > System > Tools, under the "Ping" tab, ping license.exinda.com. If this does not work (and the resolution from the name to the IP has worked), the following could be a culprit:
- The Exinda Licensing Server is offline; try again at another time
- A firewall is in the way blocking ICMP traffic
- A firewall is blocking all traffic to license.exinda.com.
- Configuration > System > Tools, under the "Console" tab, log in to the Exinda CLI and do the following commands:
- telnet license.exinda.com 80
This will determine whether it is possible to get to the Exinda license server through port 80 (the general web traffic port).
If after all of this, a connection still can't be made to the Exinda licensing server, get in touch with Exinda TAC so that they can examine the problem.
