I have a headless debian home server (Jessie, 8.9). Occasionally we have power outages. The problem is that the router doesn't boot as fast as the debian server when the electricity comes back. The router needs +1 minutes to boot up but the server boots in ~10 seconds.
My server doesn't initiate new requests for the ethernet link after the interface initialization has detected there is no link (router hasn't finished booting, won't accept connections yet). I'm using static IP set on debian.
How do I configure my interface to check again later, or delay initialization long enough for the router to finish booting and accept the connection?
