Hi Peter, Victor gave a method of stopping the warning, but Hamish was on the right track of using different IP addresses.

What operating system is running your ‘ssh 192.168.1.9’? If Linux, I expect it has support for multicast DNS and you should be able to do ‘ssh raspberrypi.local’ instead; the default hostname(1) in Raspbian being ‘raspberrypi’ and ‘local’ being a pseudo top-level domain reserved for mDNS: https://en.wikipedia.org/wiki/.local You may find the first ssh or ‘ping raspberrypi.local’ doesn't work, but it doesn't from the second on. This is just the time-out used being shorter than the time taken by the system to get a reply to its broadcast. If that works, you can give each of your Raspbian installations a different hostname that's meaningful, e.g. ‘coupe’ for your RC car that doesn't stop. https://bloggerbrothers.com/2017/01/08/name-your-pis-with-mdns-forget-the-ips-with-zeroconf/ has more detail. I haven't tried what I suggested, or what's in that article, but think the theory's correct. -- Cheers, Ralph. -- Next meeting: BEC, Bournemouth, Tuesday, 2019-10-01 20:00 Check to whom you are replying Meetings, mailing list, IRC, ... http://dorset.lug.org.uk/ New thread, don't hijack: mailto:dorset@mailman.lug.org.uk
