[atlas]trying to collect basic info about the architecture
by Wilfried Woeber, UniVie/ACOnet 05 Jan '11

05 Jan '11

Dear ATLAS-Team, I am aware of the fact that my poking and attempt to collect information may be premature, as the whole thing is still very much in development... Still, I think it would be useful for many of us to have some sort of "snapshot" regarding the behaviour of the probes and the framework they live in. The initial basic questions on my end would be: What does the term "connect", to one of the controllers, really mean in terms of TCP/IP Lingo? Like: does the thing open a TCP hose to the controller? Is communication based on UDP and/or on TCP? Is the probe capable of bufffering data for a while if connectivity to the Net is still there, but not to the controller(s)? Is there any means to (locally, on the same subnet, or even remotely) trigger or "reboot" a probe, other than disconnecting power (which means physical access required)? I am also wondering how much of this stuff is available already and where to collect it - the 'labs pool may be more appropriate than this list? Thanks to everyone who was and is involved in this fascinating project, with season's greatings and a happy (2010)++ to everyone, Wilfried. PS: for a future version of the probes or as an optional gadget: how about making the thing capable of feeding it off 2 different power plugs, e.g. a primary and a UPS? :-)

[atlas]Probe actually down?
by Richard L. Barnes 05 Jan '11

05 Jan '11

Probe #394 is reported as being down in the web GUI, but I can ping6 to it without a problem. I'm not near the probe right now, so I can't look at it or its traffic. Are there known cases where probes are alive but not reporting to their controllers? --Richard

After the registration of the probes, how can I correct the geo-location? Thanks Hartmut

[atlas]DHCP behaviour of the probe on startup
by Wilfried Woeber, UniVie/ACOnet 22 Dec '10

22 Dec '10

Hi folks, while debugging some non-probe-related issues here at my ADSL'd net @home, I was told by the provider's techie, that the probe tries to grab *two* addresses at startup. He was monitoring the ARP table in the router, saw a DHCP request and the address assigned by the DHCP Server, and immediately asfterwards, the probe sent a request for an additional address, which was granted by the server. Trying to verify that, I later found out that I can ping the probe only on the second address. [1] Has anyone seen such a behaviour? Unfortunately, I don't have access to the router (cisco 800 series) as it is fully managed by the ISP, and for my other probe we had the IP-Address hard-wired into the DHCP server for the MAC address. Thanks, Wilfried. [1] this is particularly nasty for home networks with a very small number of addresses available (a bock of 8 in may case) and a long timeout...

[atlas]how big is the limitation imposed by the req. for DHCPv4?
by Wilfried Woeber, UniVie/ACOnet 22 Dec '10

22 Dec '10

Folks, I'd like to collect input from those interested in principle to deploy groups of probes within their operational environment(s), regarding the requirement to have DHCPv4 available in order to configure the probe (for IPv4). I already came up with a coupe of locations and environments, where such a cute thing would be nice to have, but in most (if not all) of these places, there is no DHCP available (and for good reasons). As an aside to the developers, would it be feasable to connect the probe in network A, configure it for the destination network and then move it over to network B for its happy life? Cheers, Wilfried.

[atlas]Probe flapping
by Harald Firing Karlsen 21 Dec '10

21 Dec '10

Hi, My RIPE Atlas probe (MAC: 00204AC8243A) started flapping last night and is continuing to flap. It have flapped about 90 times since midnight, do you have any known problems at the moment? -- Kind regards Harald Firing Karlsen

[atlas]Question about security?
by Marco Davids (SIDN) 17 Dec '10

17 Dec '10

Hi, So how does security on the Atlas portal work? Reason for asking is that I changed the password from home yesterday, but when i logged in from work this morning, i was not asked for the new password. Maybe some kind of sessionid cookie with a long expiry time? Is that safe enough? Regards, -- Marco

[atlas]RFC5006
by Marco Davids (SIDN) 13 Dec '10

Question: Do the Atlas probes support RFC5006 (RDNSS option)? If not, would that be an idea to implement? Regards, -- Marco

Hey guys, I have had a probe move from Columbia, Maryland, USA to Cambridge, Massachusetts, USA. How do I update the registered location? --Richard
