27 Feb '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 nl-ens-as1133 and it is hosted by University of Twente in Enschede, The Netherlands 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/ <https://atlas.ripe.net/anchors/list/> Learn more about RIPE Atlas anchors at: https://atlas.ripe.net/about/anchors/ <https://atlas.ripe.net/about/anchors/> Thank you for participating in RIPE Atlas!

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?

Re: [atlas] Fwd: Re: Proble locations (Changed because of Geo-IP)
by Chris Amin 25 Feb '15

Dear Martin, I'm sorry for this, we recently made a change which keeps the location of those probes which are geolocated (i.e. *without* a manually set address) up to date. Previously such probes were geolocated once, and never again. It was never the intention to overwrite manually given locations. Unfortunately, it seems that a number of probes were erroneously marked as being automatically geolocated when in fact their owners had carefully provided a location. We are now looking at our logs to see how many probes might have been affected by this, and whether we can automatically revert the location in those cases. As for your point about not being able to enter the location, there is a text box above the map popup which should allow you to enter a textual address. If this isn't working for you, please let me know. Apologies once again.

Proble locations (Changed because of Geo-IP)
by Martin Winter 25 Feb '15

25 Feb '15

So I've noticed that (at least some) probes got the location automatically updated based on Geo IP. However, this is frequently fundamentially broken. One of my probe moved from San Jose, CA to somewhere in the middle of Texas. (Broken Geo-IP location for AT&T DSL users). (The example I talk about is proble #10770) Kind of sad... not sure how many had this happening. Specially as I took care to put the exact lat/lon in the User interface in the past. Now I can only reposition it by dragging on a map - and that seems to be broken as well (at least it fails to save when I try to correct this probes location on Chrome) I wonder how many and why there was a decision to change the location. I think the location were much better before they got force-changed. - Martin Winter

Sagan: 'Response' object has no attribute 'edns0'
by Paul Vlaar 19 Feb '15

19 Feb '15

Hi all, I'm trying to do some basic DNS UDM result parsing using Sagan. I'd like to have an easy way to extract the NSID. I followed the instruction found here: https://www.ripe.net/ripe/mail/archives/ripe-atlas/2014-May/001475.html 'from ripe.atlas.sagan import Result result = Result("your-JSON-result-blob-here") print(result.responses[0].edns0.options[0].nsid)' That didn't work, as I get: AttributeError: 'Result' object has no attribute 'responses' So I figured I need to use a DnsResult, instead. I then have the following Python code: from ripe.atlas.sagan import DnsResult import json url = "https://atlas.ripe.net/api/v1/measurement-latest/1873691/" results = json.load(urllib.urlopen(url)) for probe in results: sagan_result = DnsResult(results[probe][0]) print(sagan_result.responses[0].edns0.options[0].nsid) This gives me: print(sagan_result.responses[0].edns0.options[0].nsid) AttributeError: 'Response' object has no attribute 'edns0' After some digging through the Sagan documentation, I found out that the way to do this should be: print(sagan_result.responses[0].abuf.edns0.options[0].nsid) This might be of help to others. ~paul
