on a SOHO LAN that used gto have a good running v3 probe (25867 but it went where so many v3 probes go, dead for a few months now. yes i did usb recovery, to no avail. you gotta love v3 probes.) i unpack an unused v3 (25909) i had in my back pocket for a few years. plug it into the LAN. wait a few hours. it does not register. power LED on, LED to right of it blinks about every two seconds. web page for it, https://atlas.ripe.net/probes/25909/ shows it has been down for 1 year 11 months while, in fact, it has never been up. oddly that web page shows the correct AS, comcast, 7922, but no IP addressing. tcpdump is my friend. pcap can be found at https://archive.psg.com/240907.atlas-25909.pcap it gets dhcp etc. then twice successfully pings to nl-ams-as3333-3.anchors.atlas.ripe.net (193.0.0.164) then it does successful DNS AAAA queries for woolsey.atlas.ripe.net and reg02.atlas.ripe.net. but it never reaches out to them that i can see. then it does a successful ARP for the default gateway, 192.168.0.1 then silence and much more silence unpack another unused antique from its envelope, 25918. dns queries for different controllers, but otherwise the same story. pcap avaliable as https://archive.psg.com/240907.atlas-25918.pcap. how to further debug? randy
