Soon, I’m going to move the JeeLabs server to a new spot in the house. Out of sight, now that the setup is stable.
But to do so requires rerouting an ethernet cable to the internet modem downstairs.
To do it right, I’d like to have a “we will be back soon” surrogate server plugged into the internet modem while transitioning, so that the status is reported on-line:
I could plug in a temporary Linux box, of course, or a laptop. But I want to keep this option available at all times, so a dedicated solution would be more practical. That way I can easily take the server off-line at any moment.
This combination just needs a 5..6V power supply, and 6 wires between the RBBB and the Ether Card.
In this case, being able to configure the MAC address of the interface as well as the IP address is in fact quite convenient, because this way the modem needn’t notice the hardware switch.
Only needs about 6 Kb. Actually, I’ll probably add a wireless option and use a JeeNode instead, to report total hits every once in a while. But either way, such a “back-soon server” really doesn’t come any simpler than that!
So if one of these days you see that message while surfing at JeeLabs, you know where it’s coming from :)
PS. I’ve put the back-soon server on-line as a test, it can be reached at http://jeelabs.org:8080/.
