HTTPS interception in Atlas probes
by Stephane Bortzmeyer 03 Mar '17

03 Mar '17

After this excellent talk at NDSS 17 <https://www.internetsociety.org/doc/security-impact-https-interception>, I wanted to see if there are some Atlas probes behind such an interceptor. I cannot run on all Atlas probes (maximum daily spending limit) but I've found at least one: % python cert.py --requested 500 --area North-Central --issuer www.afnic.fr 497 probes reported [<X509Name object '/C=NL/O=OCOM/OU=Security Dep/CN=amspan01.ocom.lan/emailAddress=security(a)leaseweb.com'>] : 1 occurrences [<X509Name object '/C=BE/O=GlobalSign nv-sa/CN=GlobalSign Extended Validation CA - SHA256 - G2'>] : 496 occurrences Test #7854923 done at 2017-03-03T16:20:43Z The probe is #10035, in Amsterdam <https://atlas.ripe.net/probes/10035/#!tab-general> The cert.py program is at <https://github.com/RIPE-Atlas-Community/ripe-atlas-community-contrib>

Feature request: API call in results page
by Hugo Salgado 03 Mar '17

03 Mar '17

Hi RIPE Atlas people. I wonder if it could be possible to add an option on the "measurements" webpage of a previous stopped or running measurement, to be able to see the API call that created it. Just like the "Measurement API Compatible Specification" section, when you create one. It could be available just to the user who created it... and even with API keys obscured. That will be very handy to be able to replay and exact measurement, or to have the list of probes in a ready-to-use format. Thanks a lot! Hugo Salgado

USB stick?
by Danny Horne 02 Mar '17

02 Mar '17

Hi all, I've seen in another thread mention of a USB stick. I've got an Atlas probe coming and haven't seen mention of a USB stick anywhere else, just the need for an Ethernet connection and USB power adapter. Have I missed something? Thanks for looking Regards Danny

modifications to Atlas front-end servers
by Romeo Zwart 02 Mar '17

02 Mar '17

dear Pier, Bjørn and all, We are in the process of migrating the atlas front-end machinery from apache to nginx. Despite our extensive preparations, this change has not been completely transparent, as you have noticed, and has caused some problems with the certificate chains. The problems with the CERTs have now been fixed. Apologies for this inconvenience to everyone. Please let us know if you would spot any other anomalies in the behaviour of the Atlas service. Kind regards, Romeo Zwart

SSL issue with atlas.ripe.net
by Pier Carlo Chiodi - Active Network S.p.A. 02 Mar '17

Hello, I'm facing an issue while using Atlas API. Some connections (not all) to https://atlas.ripe.net fail because of what seems to be an invalid certs chain. It looks like that an intermediate cert is missing. SSLLabs too reports something similar: https://www.ssllabs.com/ssltest/analyze.html?d=atlas.ripe.net&s=193.0.6.158 $ openssl s_client -connect atlas.ripe.net:443 -servername atlas.ripe.net CONNECTED(00000003) depth=0 C = NL, ST = Noord-Holland, L = Amsterdam, O = RIPE NCC, CN = atlas.ripe.net verify error:num=20:unable to get local issuer certificate verify return:1 depth=0 C = NL, ST = Noord-Holland, L = Amsterdam, O = RIPE NCC, CN = atlas.ripe.net verify error:num=27:certificate not trusted verify return:1 depth=0 C = NL, ST = Noord-Holland, L = Amsterdam, O = RIPE NCC, CN = atlas.ripe.net verify error:num=21:unable to verify the first certificate verify return:1 --- Certificate chain 0 s:/C=NL/ST=Noord-Holland/L=Amsterdam/O=RIPE NCC/CN=atlas.ripe.net i:/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert SHA2 High Assurance Server CA --- Server certificate -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- subject=/C=NL/ST=Noord-Holland/L=Amsterdam/O=RIPE NCC/CN=atlas.ripe.net issuer=/C=US/O=DigiCert Inc/OU=www.digicert.com/CN=DigiCert SHA2 High Assurance Server CA --- ...

changing probes of a given measurement
by JORDI PALET MARTINEZ 01 Mar '17

01 Mar '17

Hi, Is it possible to change some of the probes of a given measurement? The issue is that I’ve a set of 10 probes for a specific measurement and it seems that 1 of them is no longer connected. Last time I’d this situation, I created a new measurement with the same probes except the failed one, but I wonder if it is possible to “modify” the actual measurement instead of creating a new one?
