Sharing Stats?
by Dan Luedtke 03 Aug '12

03 Aug '12

Hello everyone, what are your opinions on sharing stats from a probe to the public? My idea: I have a public probe and public UDMs running, and I would like to embed the "last 8 hours" graphs into a website where people can see it, even those that do not have access to RIPE Atlas. Do you think it is a good idea to ask for a feature that splits the "Public" checkbox into two ones saying "Public (ATLAS Community)" and "Public (Internet)"? best regards, Dan -- Dan Luedtke http://www.danrl.de

Port blocking statistics
by Bartsch, Rene 25 Jul '12

25 Jul '12

Hi, when charting the internet it would be useful to have an oversight about ISPs blocking ports. Especially discussions about network neutrality should be based on hard facts instead of polemic discussions. So I suggest to check the connectivity of the protocols listed in http://www.iana.org/assignments/service-names-port-numbers/service-names-po… once a week as built-in measurement.

Should these measurements be discontinued? These networks are no more visible. http://www.ris.ripe.net/dashboard/128.0.24.0/24 http://www.ris.ripe.net/dashboard/128.0.0.0/21 -- Tuomo Soini <tis(a)foobar.fi> Foobar Linux services +358 40 5240030 Foobar Oy <http://foobar.fi/>

Fwd: [ipv6-wg] New on RIPE Labs: Test your IPv6 Reachability by Using RIPE Atlas (now visualised)

fyi. I think this mail was not sent to this mail list. Cheers, kix -------- Mensaje original -------- Asunto: [ipv6-wg] New on RIPE Labs: Test your IPv6 Reachability by Using RIPE Atlas (now visualised) Fecha: 17/07/2012 14:32 Remitente: Mirjam Kuehne <mir(a)ripe.net> Destinatario: ipv6-wg(a)ripe.net [apologies for duplicate mails] Dear colleagues, As announced in earlier, it is possible for RIPE NCC members to do IPv6-traceroutes from all RIPE Atlas probes to IPv6 destinations. In this new article on RIPE Labs we present a first experimental analysis and a prototype visualisation of the traceroute results: https://labs.ripe.net/Members/emileaben/visualise-your-ipv6-connectivity-us… Kind Regards, Mirjam Kuehne RIPE NCC -- Rodolfo García Peñas (kix) http://www.kix.es

Concurrent traceroute issues on the probes
by David Lebrun 23 Jul '12

23 Jul '12

Hi all, I was wondering whether the probes can perform multiple concurrent traceroutes toward different destinations, and if so, are they able to differentiate the replies ? I just ran into this problem with paris-traceroute, the path were completely mixed up and stderr output looking like the following messages multiple times (IP addresses redacted): [WARN](TracertImpl.cc, 368)A reply received with bad original destination address A.B.C.D, should be W.X.Y.Z [WARN](TracertImpl.cc, 326)Bad return flow id 0x4d2 from E.F.G.H [WARN](TracertImpl.cc, 331)ICMP reserved words 0 0 0 0 0 As the probes use paris-traceroute, I prefer to be sure that the results are not flawed.

Embedd built-in measurement page into website
by Bartsch, Rene 23 Jul '12

Hi, is there any way to embedd the "Built-in Measurements"-JQuery-Frame of my probes into a publically accessible website? Thanx for any hint, Renne -- Sent with love from the new tine 2.0 email client ... Please visit http://tine20.org

High inbound traffic causing packet loss?
by Tibor Djurica Potpara 23 Jul '12

23 Jul '12

Hello! I have just received an Atlas probe and I have been observing some weird readouts on the Atlas portal. Especially, occasional packet loss and considerable jitter, even to first and second hop destinations. I am surprised because even though I am a home user, I have a very stable connection (FTTH, 100/10 Mbps) and I've never experienced such connectivity issues. I've attached the probe directly to the ISP-provided switch that doesn't do IGMP snooping and since IP multicast is used for IPTV, high traffic (up to 50 Mbps) is occasionally flooded to all the switch ports. Taking into account that the probe is underpowered in terms of CPU, is it possible that it cannot handle such traffic and thus reports packet loss? If such is the case, I will move the probe behind a router to filter the multicast streams out. Best regards, Tibor Djurica Potpara

Flood-ping to measure packet loss?
by Bartsch, Rene 18 Jul '12

18 Jul '12

Hi, I've just started hosting a probe and I'm new to the list, so a "Hello" to all! :) Does the probe send simple pings or does it send flood pings (e.g. ping -f -c 1000 <destination>) for detection of packet loss?

Firmware 4470 to be released soon
by Ann Barcomb 11 Jul '12

11 Jul '12

Hello, Probe firmware version 4470 will be released soon. This version includes a small data structure change from 4460 which only affects DNS measurements: the addition of the optional field 'src_addr'. We have also published a correction for version 4460, which mistakenly listed a field 'src' for DNS measurements. This field does not exist in 4460. http://weir-dev.atlas.ripe.net/doc/data_struct#v4460_dns Kind Regards, Ann -- Ann Barcomb RIPE NCC Community Builder http://www.ripe.net Measurements Community Building +31 20 535 4444
