HTTP or not HTTP?
by Stephane Bortzmeyer 31 Jul '13

I'm surprised to see in UDM documentation that you can do HTTP measurements: https://atlas.ripe.net/doc/udm#http-http6 But I do not find this option in the "Choose a measurement" menu of the Web interface. And it is not documented in the REST API: https://atlas.ripe.net/doc/measurement-creation-api/ > type: One of ping,traceroute,dns or sslcert So, can we do HTTP measurements with the Atlas probes?

Outdated documentation to delete
by Stephane Bortzmeyer 30 Jul '13

IMHO, the "mechanize" example in <https://atlas.ripe.net/doc/code#access_from_scripts> is useless now that we have an API and should be deleted.

Spoofing the source IP address from a probe?
by Stephane Bortzmeyer 30 Jul '13

30 Jul '13

I read in the interesting <http://www.internetsociety.org/blog/2013/06/can-we-stop-ip-spoofing-internet> about BCP38 (anti-spoofing): > Another possibility that was suggested is using RIPE Atlas probes to > probe network capabilities (or shall we say incapabilities?). AFAIK, Atlas probes cannot currently perform these tests, am I correct?

Hi, Probably we don't need to spoof all address space, instead only if spoofing enabled just spoof to some predefined address range.

Re: [atlas] Outdated for more than one day?

Hello, The probe ID is 10156. It is attached to a third interface on my router. The graphs have been stalled for the last four days. The probe went online on June 26 and all was well until this happened on July 24. Thanks for looking.

Outdated for more than one day?
by Fred Grayson 27 Jul '13

Hello, Recently, all Built-in-Measurments for my probe began showing "Outdated for more than one day" and none of the graphs are current, most show some white space at the far right hand side. My Total Uptime: 99.56% (31d, 22h, 30m) and I have power cycled the device twice trying to solve the problem. Any ideas on how to fix this will be appreciated. Thanks, FG

Ping Fails (ns.ripe.net)
by AlbyVA 23 Jul '13

23 Jul '13

In reviewing My Probe stats, it appears that (ns.ripe.net) was once able to ping the server, but now it appears to be failing. All my other ping stats under My Probe show successful pings to other servers, but for some reason ns.ripe.net is failing. Does anybody have a suggestion of what might be going on, since ping is working to all the other servers. -Alby

No address in the results when ping or traceroute fail?
by Stephane Bortzmeyer 23 Jul '13

23 Jul '13

When a ping or traceroute emasurement fails, we do not know the IP address of the probe (empty "from" and no "src_addr"), which is annoying when you want to analyze the possible causes of the failure: { "size": 20, "addr": "2620:0:2d0:200:0:0:0:7", "min": -1, "rcvd": 0, "from": "", "dst_name": "2620:0:2d0:200:0:0:0:7", "af": 6, "timestamp": 1374395985, "fw": 4520, "proto": "ICMP", "name": "www.icann.org", "prb_id": 3953, "result": [ { "error": "sendto failed: Network is unreachable" }, { "error": "sendto failed: Network is unreachable" }, { "error": "sendto failed: Network is unreachable" } ], "max": -1, "dup": 0, "avg": -1, "type": "ping", "dst_addr": "2620:0:2d0:200::7", "sent": 0, "msm_id": 1013576 },

Hi I'm Arthit from Bangkok. New here. The switch at the probe is now at "3G/4G". Should i change to WISP or AP? thanks, Art -- เครือข่ายพลเมืองเน็ต -- "เปิดเน็ต เปิดใจ" Thai Netizen Network -- "Open Net. Open Mind." https://www.facebook.com/thainetizen

Strange and undocumented (?) result in traceroute JSON output
by Stephane Bortzmeyer 17 Jul '13

17 Jul '13

Measurement #1013405 contains: "result": [ { "x": "*" }, { "late": 20, "ttl": 61, "from": "88.79.15.141", "size": 96 }, { "x": "*" }, { "x": "*" } While "late" is documented <https://atlas.ripe.net/doc/data_struct#v4400_traceroute>, the lack of "rtt" field is not and crashes tools like json2traceroute.py.
