Exact semantics of DNS' use_probe_resolver
by Stephane Bortzmeyer 17 Mar '15

17 Mar '15

The DNS-specific option use_probe_resolver is mentioned in <https://atlas.ripe.net/docs/measurement-creation-api/> but with little indication of the semantics. My experience is that some probes (with the default retry=0) return several responses, with the same "prb_id", but different "from". I assume it means the probe had several resolvers configured and tried them all. Am I correct? It may question some conclusions of <https://labs.ripe.net/Members/stephane_bortzmeyer/how-many-ripe-atlas-probe…>. Is there an option to switch to the more typical behaviour of a DNS client (try the first resolver configured and switch to the second if the first does not reply)?

Visualising RIPE Atlas Anchor Measurements
by Vesna Manojlovic 17 Mar '15

17 Mar '15

Dear colleagues, Salim Gasmi, one of the RIPE Atlas anchor hosts, visualised the measurements collected by the RIPE Atlas anchor. This monitoring page is publicly available and allows to analyse topology changes and helps debugging network issues. Please find more details on RIPE Labs: https://labs.ripe.net/Members/salim_gasmi/visualising-ripe-atlas-anchor-mea… Kind regards, Vesna

Re: [atlas] Please set your NIC handle for your RIPE Atlas anchor
by Paul Vlaar 17 Mar '15

17 Mar '15

Dear RIPE Atlas staff, I'm a little confused. I need to add a NIC handle, you say. "What is a NIC handle? A NIC handle is the unique identifier of a person. It is basically the person's unique ID and it helps to keep different people with the same name apart from each other. Whenever a person object is referenced in another object, they are referenced by their NIC handle ("nic-hdl:") and not by their name. See an example person object" How can a handle meant for a person be used for a machine? Is this correct? Thanks, Paul Vlaar Afilias On 11/3/15 12:59 PM, RIPE Atlas (no reply) wrote: > Dear Paul Vlaar, > > We noticed that you haven't added the NIC handle for your RIPE Atlas > anchor yet.

Internet Exchange Nepal (NPIX) has joined RIPE Atlas anchors
by Michela Galante 10 Mar '15

10 Mar '15

Dear RIPE Atlas users, We're happy to announce that another RIPE Atlas anchor has joined the network and is now available as a target for probe hosts conducting their own user-defined measurements. The new anchor is called np-ktm-as45170 and it is hosted by the Internet Exchange Nepal (NPIX) in Kathmandu, Nepal, and sponsored by APNIC. Anchoring measurements (ping, ping6, traceroute and traceroute6) are scheduled towards this anchor from all the other anchors as well as several hundred probes, providing a continual overview of regional reachability. Results of these measurements are available as raw data in JSON format, and visualised on the map and "seismograph" with many configurable features. You can access the anchoring measurements for all anchors at: https://atlas.ripe.net/anchors/list/ Learn more about RIPE Atlas anchors at: https://atlas.ripe.net/about/anchors/ Thank you for participating in RIPE Atlas! Kind Regards, RIPE Atlas Team atlas(a)ripe.net

Mistakenly sent "please register your probe" emails
by Robert Kisteleki 05 Mar '15

05 Mar '15

Dear RIPE Atlas users, As part of our regular development schedule, the development team rolled out a new version of the infrastructure components yesterday. As a side-effect, due to a mistake on our end, some users received emails urging them to register their probe(s), even though this has already been done. If you got such a mail although you've done your part, then please ignore this mail. Our apologies for the confusion. Regards, Robert Kisteleki

some probes not returning NSID
by Paul Vlaar 26 Feb '15

26 Feb '15

Hi all, it appears that some probes never return NSID, when requested, while others do, for the same query. For example: https://atlas.ripe.net/measurements/1875836/#!general As you can see NSID is set to True. These are the raw results from the two probes, for a one-off DNS UDM: results = { u'6012': [{u'lts': 230, u'proto': u'UDP', u'from': u'193.0.19.108', u'msm_id': 1875836, u'af': 4, u'timestamp': 1424384037, u'fw': 4670, u'msm_name': u'Tdig', u'prb_id': 6012, u'result': {u'abuf': u'OQGEAAABAAEAAAABA29yZwAABgABwAwABgABAAADhAAzAmEwA29yZwthZmlsaWFzLW5zdARpbmZvAANub2PAKHfjQ2sAAAcIAAADhAAJOoAAAVGAAAApEAAAAAAAACUAAwAhbnMwMDBiLmFwcDcubnJ0MS5hZmlsaWFzLW5zdC5pbmZv', u'rt': 312.971, u'NSCOUNT': 0, u'QDCOUNT': 1, u'answers': [{u'RNAME': u'noc.afilias-nst.info.', u'NAME': u'org.', u'MNAME': u'a0.org.afilias-nst.info.', u'TTL': 900, u'SERIAL': 2011382635, u'TYPE': u'SOA'}], u'ID': 14593, u'ARCOUNT': 1, u'ANCOUNT': 1, u'size': 132}, u'src_addr': u'193.0.19.108', u'group_id': 1875836, u'type': u'dns', u'dst_addr': u'199.19.56.1'}], u'10039': [{u'lts': 166, u'proto': u'UDP', u'from': u'96.237.232.254', u'msm_id': 1875836, u'af': 4, u'timestamp': 1424384040, u'fw': 4670, u'msm_name': u'Tdig', u'prb_id': 10039, u'result': {u'abuf': u'qxGAgAABAAEAAAABA29yZwAABgABwAwABgABAAAB3QAzAmEwA29yZwthZmlsaWFzLW5zdARpbmZvAANub2PAKHfjQ2UAAAcIAAADhAAJOoAAAVGAAAApD6AAAAAAAAA=', u'rt': 8.299, u'NSCOUNT': 0, u'QDCOUNT': 1, u'answers': [{u'RNAME': u'noc.afilias-nst.info.', u'NAME': u'org.', u'MNAME': u'a0.org.afilias-nst.info.', u'TTL': 477, u'SERIAL': 2011382629, u'TYPE': u'SOA'}], u'ID': 43793, u'ARCOUNT': 1, u'ANCOUNT': 1, u'size': 95}, u'src_addr': u'192.168.13.40', u'group_id': 1875836, u'type': u'dns', u'dst_addr': u'199.19.56.1'}] } Sagan tells me, for probe 6012, responses[0].abuf.raw_data is: {'HEADER': {'AA': True, 'QR': True, 'AD': False, 'NSCOUNT': 0, 'QDCOUNT': 1, 'ANCOUNT': 1, 'TC': False, 'RD': False, 'ARCOUNT': 1, 'CD': False, 'ReturnCode': 'NOERROR', 'OpCode': 'QUERY', 'RA': False, 'Z': 0, 'ID': 14593}, 'AnswerSection': [{'Retry': 900, 'Name': u'org.', 'NegativeTtl': 86400, 'Refresh': 1800, 'MasterServerName': u'a0.org.afilias-nst.info.', 'Expire': 604800, 'MaintainerName': u'noc.afilias-nst.info.', 'TTL': 900, 'Serial': 2011382635, 'Type': 'SOA', 'Class': 'IN', 'RDlength': 51}], 'QuestionSection': [{'Qclass': 'IN', 'Qtype': 'SOA', 'Qname': u'org.'}], 'EDNS0': {'ExtendedReturnCode': 0, 'Option': [{'OptionCode': 3, 'OptionName': 'NSID', 'NSID': u'ns000b.app7.nrt1.afilias-nst.info', 'OptionLength': 33}], 'UDPsize': 4096, 'Version': 0, 'Z': 0, 'Type': 'OPT', 'Name': u'.'}} NSID is present. And for 10039: {'HEADER': {'AA': False, 'QR': True, 'AD': False, 'NSCOUNT': 0, 'QDCOUNT': 1, 'ANCOUNT': 1, 'TC': False, 'RD': False, 'ARCOUNT': 1, 'CD': False, 'ReturnCode': 'NOERROR', 'OpCode': 'QUERY', 'RA': True, 'Z': 0, 'ID': 43793}, 'AnswerSection': [{'Retry': 900, 'Name': u'org.', 'NegativeTtl': 86400, 'Refresh': 1800, 'MasterServerName': u'a0.org.afilias-nst.info.', 'Expire': 604800, 'MaintainerName': u'noc.afilias-nst.info.', 'TTL': 477, 'Serial': 2011382629, 'Type': 'SOA', 'Class': 'IN', 'RDlength': 51}], 'QuestionSection': [{'Qclass': 'IN', 'Qtype': 'SOA', 'Qname': u'org.'}], 'EDNS0': {'ExtendedReturnCode': 0, 'Option': [], 'UDPsize': 4000, 'Version': 0, 'Z': 0, 'Type': 'OPT', 'Name': u'.'}} NSID is missing. Why is this? I've tried increasing the payload size, this makes no difference. I get the same when I try for SOA . @ k.root-servers.net: Compare these outcomes: https://atlas.ripe.net/measurements/1875933/ https://atlas.ripe.net/measurements/1875926/ It appears to me that probe 10039 (or its network) has a problem of sorts, causing this. It would be great if faulty probes can be weeded out, if this is really the case. BTW, I am always getting "null" on the NSID field in the web interface, regardless of whether it lives in abuf, or not. This seems to be a bug. ~paul

It could be interesting to use Atlas probes for such measurements, no?
