From the above info, are you able to judge whether the unit might still be hackable, or is likely dead ?Ģ. The green LED on the Pi's LAN stays off - I understand this is normal for a Pi 3B+ and shows it has made a gigabit link rather than 10/100M.ġ. Incidentally the amber LED on the Pi's LAN interface flashes during boot of the Dockstar, then stays on solid. So probably the packets were just a by-product of the Pi's LAN interface coming up when the Dockstar is powered on and the link-level connectivity comes up. However on closer inspection these packets all had a source MAC address of the rasp Pi: there appeared to be no other MAC address sending out packets. I could see a flurry of packets when the Dockstar was switched on, which looked promising: ICMP6 neighbour solicitations, multicast DNS and even a few BOOTP/DHCP Request packets. Next I tried to snoop the network to see if there was any evidence of the Dockstar trying to do DHCP : I connected it directly to an isolated raspberry Pi which is running a DHCP server (dnsmasq) on its wired LAN interface. I tried swapping the TX and RX connections in case I got that wrong, but still no output visible when booting. I made a wee cable to connect my raspberry Pi GPIO UART pins to the Dockstar's serial pins, and used 'screen /dev/serial0 115200' to see if there was any serial output when booting the Dockstar, but see none. Then I read online that it was a good idea to prevent the dockstar from 'phoning home' to prevent firmware updates. I connected it to my home network to see if it got an IP address from my broadband router, but it didn't appear to : an nmap -sP of my 192.168.10.0/24 showed no new hosts. When it powers on, the LED flashes green for 10 seconds, then flashes amber indefinitely, which I understand means it failed to boot. Since then it has been sitting unused in a cupboard. I bought the unit new about 10 years ago, registered it on, and used it for about 6 months or so. I recently found an old Seagate Dockstar which I would like to re-use as a network backup & monitoring server (since it is such a neat compact low-power unit), and would appreciate your advice on how feasible it would be to get it loaded with Debian or similar, given its current behaviour, outlined below :.
