After cycling the power on the Raspberry Pi 3, if I try to ssh to it (from Ubuntu), I get a "Resource temporarily unavailable" response.
If I ping Ubuntu --> Pi 3, it just hangs.
If I leave it hanging, and then ping Ubuntu <-- Pi 3, packets start coming in both directions. I can then ssh just fine. The same thing happens when I reverse the order and ping Ubuntu <-- Pi 3 first. I also tried pinging only with ip addresses.
Why would ssh only work after pining from both directions? Every time I reset the power I have to do this. It's a pain because I can't use the Pi 3 in headless mode.
The output of ssh -vvv is below:
