[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]option ntp-servers ?
by Marco Davids (SIDN) 09 Dec '10

09 Dec '10

Hi, Question: does the Atlas-probe obey to the 'option ntp-servers' DHCP option? If not, mine could be into trouble, since I don't allow outbound NTP-requests. (Sorry if this has been asked before, I am new to this list and haven't found the archive just yet) Regards, -- Marco

[atlas]IPv4 and IPv6 to the same machine(s)...
by Wilfried Woeber, UniVie/ACOnet 07 Dec '10

07 Dec '10

How much effort would it be to add a test and the graph to labs.ripe.net on IPv6? Just checked, it still has an IPv6 address. Btw, Mirjam (on bcc:), the new Labs site does no longer show the address for the incoming connection. Could this be re-instated, please? If possible it should go to somewhere in the header, like next to the login-name... On a more general aspect, I am looking for a good idea to present the measurement data for the same machine(s) for v4 and v6 either in the same graph "on top of each other" or "next to each other"... This could easily evolve into a graphical v6-sanity-check vehicle :-) Wilfried.

[atlas]Atlas probe showing up as Never seen
by Harald Firing Karlsen 06 Dec '10

06 Dec '10

Hi, I installed my RIPE Atlas-probe yesterday and it still shows up as "Never seen" on the Atlas website. Everything looks good networking-wise (it have received DHCP-offer, etc), but it still shows up as "Never seen" on the Ripe Atlas website. The MAC-address is 00204AC8243A and the IP-address is 91.209.30.2. I hope you can solve this. -- Kind regards Harald Firing Karlsen

[atlas]probe locations
by Florian Obser 06 Dec '10

06 Dec '10

Hi, so, I had a look at the probe locations at https://atlas.ripe.net/ looks like there is a probe on every continent... except Antarctica! How cool would that be! Maybe there is someone on this list who knows someone who knows someone... ;) While discussing this with a friend we both noticed that the coolness could only be topped by a probe on ISS. Looking at the registration page this seems easy enough, "Method of delivery*: Other, please specify: Soyus or Ariane 5" "Hosting Location" on the other hand will probably be a pain in the ass. Regards, Florian -- I remember yesterday, but the memory is in my head now. Was yesterday real? Or is it only the memory that is real?

[atlas]DNS records for the probes' internet address
by Tore Anderson 03 Dec '10

03 Dec '10

Hi list, I've got a probe connected to my home broadband connection, which might change its WAN address whenever my ISP feels like it should. I just thought it would be a nice feature if the probes had an A record in DNS that were automatically updated to match the current external address. Like probe-121.atlas.ripe.net or something. That way I would have a hostname I would be sure that points to the WAN address of my CPE whenever I want to log on to my home network from somewhere else. I would think such a feature would be a small incentive for home broadband users to become probe hosts. On an unrelated note, the graphs for the probe in question (#121) doesn't work, they're all gray, even though the probe is up.

[atlas]FYI probe problems after power failure
by Jelte Jansen 03 Dec '10

03 Dec '10

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Today I had a power failure, and luckily everything came back up when I fixed it. However, a while later, I wondered if the probe had too, and it had not. The status page said it was up, but it hadn't reported data for about 6 hours (grey graphs). I assume I hit one of the problems in the FAQ: - --- Technical background: the probe tries to get current time indication using NTP upon booting, which sometimes fails. This causes the probe to think the curent date is November 1999, which confuses it a lot; it doesn't register properly or it sends measurement data for the twentieth century which is immediately discarded by the system. We plan to convince the probe to insist on vaild NTP or acquire some other time indication. The fix will be deployed in a firmware update. - --- Since the probe boots a lot faster than my gateway, I guess it never retried NTP. Powercycle fixed it indeed. So the lesson here is (at least until there is an update that retries ntpdate, or something), if the machine that provides your Internet connection takes a while to boot up, and they are both powered on at the same time, you may need to powercycle your probe.

[atlas]Inaccurate uptime tracking?
by Richard L. Barnes 02 Dec '10

02 Dec '10

Hey guys, I'm seeing an inconsistency between the reported uptime and the actual measurements from probe #394. On the one hand, the probe info page reports only a little over an hour of uptime: Total Uptime: 0d, 1h, 1m Connect at: Disconnect at: 2010-12-02 02:38:06 UTC (still connected) 2010-12-01 04:22:43 UTC 2010-12-01 04:28:42 UTC But the graphs for the last 8 hours show only a brief down-time; roughly: Disconnect: 2010-12-02 02:27:00 UTC Reconnect: 2010-12-02 02:35:00 UTC This wouldn't bother me much if uptime weren't tied to chances to win an iPad :) --Richard

[atlas]atlas win!
by Florian Obser 01 Dec '10

01 Dec '10

Hi, we are running two probes. One behind my private dsl line at home, one in our data centre. I noticed that the IPv6 ping times to m.root-servers.net are more then twice as bad from our data centre compared to the dsl probe. As it turns out at home I'm talking to the m-root instance in Paris while in the data centre we were talking to the instance in Tokyo(?) It looks like this: http://eafc8bd05a0435ef14d31bbff29687dd7b71c3ca.de/m.root-servers.net.v6.png Not _that_ important in the great scheme of things but non the less quite nice ;) Thanks!

[atlas]P466 - inconsistent readings?
by Wilfried Woeber, UniVie/ACOnet 30 Nov '10

30 Nov '10

Hi Team, could you pls. have a look at the grpahs of 466 and the list of "perceived" outages for the probe? While I can't prove that there wasn't some problem with my ADSL link at home (while sitting in the office :-) ), the graphs for the pings seem to indicate that the probe was alive and kicking all the time. I may be misreading some stuff, though.... Wilfried

[atlas]some comments regarding the user interface - re-sizing and outage(s)
by Wilfried Woeber, UniVie/ACOnet 30 Nov '10

30 Nov '10

Just minor cosmetics, and for the to-do-list :-) - the probe and measurements display reacts to a resizing of the window, e.g. from partial screen to full-screen, by redrawing the inforamtion and using all the real estate, but does NOT redraw on a switch back to a smaller size. (IE7, W/XP prof. SP3) - regardig the "Uptime" panel, I'd like to see the most recent outage included by default (the UTC stamp of most recent down transition, the most recent up transition and the duration). Alternatively, I'd be happy to make the selection for "Show last 25 connections sticky, maybe by giving the number of entries to display. Cheers, Wilfried.

[atlas]IPv4 DHCP and varying addresses
by Wilfried Woeber, UniVie/ACOnet 25 Nov '10

25 Nov '10

Having a simple question regarding DHCP and varying addresses within a subnet... While I *do* have access to the config of the DHCP server that delivers addresses to 414, and thus the probe will always get that same IP address, I *do not* have access to configure the DHCP service in my ADSL CPE (yet), which means that the individual address given to the probe may change over time. I guess this is expected and being taken care of by the system, but wanted to double-check. Thanks, Wilfried.

[atlas]The probes and IPv6
by Wilfried Woeber, UniVie/ACOnet 25 Nov '10

25 Nov '10

Just had a look again at the info page for my 414, in the "Configuration" panel. While this thing does have IPv6 connectivity and performs measurements just OK, the section "IPv6", next to the MAC Address, is empty. Bug or "reserved for future use"? While we did the EUI-64 math locally to generate a DNS AAAA entry derived from the MAC, some folks may be better off to see the auto-conf'd address. As an aside, for the "ideas stack", it would be hip to have a means of educating the probe about an IPv6-transport-capable DNS server. I know, there are some issues with this idea :-/ All the best, Wilfried. PS: Looking forward to see probe #2, 466, becoming visible as living in my village, after making pole position for #1 already :-)

[atlas]Some issues today
by Robert Kisteleki 24 Nov '10

Dear All, As you already know, RIPE Atlas is in a prototype phase. A good illustration for it is an issue we had today. We're still investigating the cause, but in the meantime we had to ignore some data points for a subset of the probes -- please don't be surprised to see missing parts of your probe graphs for today. Thanks for your understanding, Robert

[atlas]warning pop-up in IE for the various atlas-related pages
by Wilfried Woeber, UniVie/ACOnet 24 Nov '10

24 Nov '10

Folks, I noticed that I have to ack a warning pop-up (served by IE7 ;-) ) for each page that is realted to the atlas stuff. IE complains about a mix of secured and unsecured components on the page. In principle I'd prefer continuing with httpS, but the warnings are a real nuisance. Anyone else seeing this? Btw, the Labs stuff shows the same behaviour. Wilfried.
