See > https://atlas.ripe.net/faq#how-does-the-probe-connect Thanks for the suggestion - I had seen that but didn't have the stanza matching by client ID as I didn't think it was necessary (MAC address alone should be sufficient, I would've thought?). I have added it now, but it hasn't helped. > Maybe you can capture the dhcp traffic with tcpdump to see if the server > sends something the probe doesn't like? Sure. I've placed a copy of the the request/reply at http://dl.rsx11.net/misc/atlas_probe_dhcp.txt. I've redacted the MAC addresses (aa:bb:cc... is the MAC of the probe) but everything else is unchanged. I don't see anything unusual - please let me know if you'd like a copy of the raw tcpdump output. I also received an off-list suggestion regarding a possible duplicate IP so I've changed the IP assigned to the probe without it making any difference. Not sure if it makes a difference, but I do also have rtavd and DHCPv6 servers running on the same network (IPv6 connectivity to/from the probe was working fine until this problem started). -mj -- Michael-John Turner mj at mjturner.net <> http://mjturner.net/
