3d downtime reported - why?
by Daniel AJ Sokolov (lists) 02 Nov '11

02 Nov '11

Hello, I have noticed that my probe data on the atlas.ripe.net-website reports at downtime of over 3 days: 2011-10-25 04:17:20 UTC to 2011-10-28 08:04:53 UTC. In fact, my connection was not down - maybe a few minutes (that seems to happen regularly), but everythin longer we would have noticed. We use this internet connection most of the day. My probe ID is not unter 500 but over 1000. Is this an error in the database, a problem with the reporting system or any other known bug? Did anyone else experience something like this? Or is there some issue I can resolve locally? Thank you Daniel AJ -- My twitter feed: @newstik http://twitter.com/newstik

Probes, static network configuration and upcoming firmware
by Robert Kisteleki 10 Oct '11

10 Oct '11

Dear Atlas hosts, We're about to release a new firmware version that supports more built-in measurements as well as prepares the probes for the User Defined Measurements feature. We have recently discovered that there's a compatibility issue with the upcoming firmware and (non-DHCP) static network configuration. In order to avoid problems that would come up in this case, we have temporarily disabled the static network configuration panel. We are in the process of releasing a corrected firmware, and enable static configuration for this version automatically. For the probes that already have static configuration up and running: there's nothing you need to do, we'll make sure that during the upgrade these probes keep their static network configuration. We apologise for the inconvenience this may cause. Regards, Robert

The letter from the student Samara State Aerospace University
by Artem Onoprienko 23 Sep '11

23 Sep '11

Hello, I’m a student of Samara State Aerospace University. My name is Artem Onoprienko. I study at electronis engineering faculty with specialization in network technologies. I'm going to write a thesis project. I would like to be engaged in monitoring mechanisms of the Internet, and both hardware, and software part. In my work I would like to consider the possibility of additional quality criteria according to the IETF RFC 2544, and the work being done in the Samara State Aerospace University ( http://arxiv.org/abs/0907.3710 This work was presented at the conference in Lisbon. In this work, to measure the bandwidth using network testing packages of various sizes) As a first step I would like to see the ability to add these features to the RIPE Test Box. But I found no technical documentation about RIPE’s construction, and it’s electrical components. I would be grateful if you would give a link to documentation about hardware and software construction of the Ripe TestBox. It will be great help for me. With best regards Artem Onoprienko

Automatic notification about down probes: if your probe has been down for some time, you'll get a one-time automatic notification. This happens after five consecutive days of downtime. 2. Static network configuration: after the testing round with volunteers, we decided to make this feature publicly available, thus released the 4.030 firmware version.

R: Email or SMS alert when probe goes offline/online
by Simone Nulchis 07 Sep '11

07 Sep '11

Hi all, >What do other participants think about having email alerts when a probe goes offline or online? I think it could be a nice feature; in my opinion it should be implemented in "my probe" section of Ripe ATLAS under "Probe's Settings" a specific section that permits to enable such feature and customize the threshold and contact addresses.

New Face(s) in the Measurements and Tools Area
by Daniel Karrenberg 07 Sep '11

07 Sep '11

Gentlepeople, I am very happy to announce that we have a new community builder for measuremnts and tools: Vesna Manjolovic. Many of you will know Vesna already as a trainer and through her very enthousiastic work on our IPv6 promotion and IPv6 related measurements. Vesna has been with the RIPE NCC for more than 10 years; it gives me great pleasure to promote her to a position that makes optimal use of her capabilities and ambitions. Vesna's first priorities will be to establish relationships with current and potential sponsors of RIPE Atlas and to help develop a plan for the evoloution of RIPE TTM. RIPE Atlas sponsors and RIPE TTM customers will hear from her soon. The decision to hire internally not only affirms that initiative and effort are rewarded at the RIPE NCC; it also provides the budgetary room to engage another person to help with the community building for measurements: Ann Barcomb will therefore join Vesna in October. >From that time both Vesna and Ann will start to work on additional goals such as building a strong community around RIPEstat. Please join me in welcoming Vesna and help her to achieve her goals, which are also our common goals. Daniel

Doing this monitoring-style is not a job for the NCC, IMHO, as this certainly involves way more work that one might think at first. This is a case for your local monitoring solution, which does that job much better. That being said, it might make sense to e-mail hosts if a probe has been down for a *long* time (something like "one e-mail per week of downtime"), just to catch dead hosts and unnoticed configuration fails. - D.

Email or SMS alert when probe goes offline/online
by Robert 07 Sep '11

07 Sep '11

What do other participants think about having email alerts when a probe goes offline or online? I'd like this is at will alert me to any network issue as soon as it happens allowing for that issue to be investigated and rectified. This means that the alert could serve a dual purpose: . Increased network uptime . Greater availability of the RIPE Atlas Probe (and thus increased data gathering). Anyway, this is something that I'd like to see - email alerts at a minimum. Robert

This might not actually be desirable until the probes stop crashing so often :) It might be more useful to have alarms that trigger on things like sudden or sustained increases in latency or loss, configurable by the probe host. --Richard On Sep 6, 2011, at 10:35 PM, Robert wrote: > What do other participants think about having email alerts when a probe goes offline or online? > > I’d like this is at will alert me to any network issue as soon as it happens allowing for that issue to be investigated and rectified. > > This means that the alert could serve a dual purpose: > > · Increased network uptime > · Greater availability of the RIPE Atlas Probe (and thus increased data gathering). > > Anyway, this is something that I’d like to see – email alerts at a minimum. > > > Robert >

[atlas]Apache again....
by Viktor Naoumov 30 Aug '11

30 Aug '11

Back to apache... 'Listen 8080' was a bad solution because it opens apache to the world. Instead we should do now: Listen 127.0.0.1:8080 #Listen localhost:8080 Having Listen localhost:8080 <VirtualHost *:8080> prevents apache from starting with the following message: zelenka-dev:/etc/apache2# /etc/init.d/apache2 restart Restarting web server: apache2 ... waiting (98)Address already in use: make_sock: could not bind to address 127.0.0.1:8080 no listening sockets available, shutting down Unable to open logs Action 'start' failed. The Apache error log may have more information. failed! looks like it because zelenka-dev:/etc/apache2# host localhost localhost has address 127.0.0.1 localhost has IPv6 address ::1 but not sure yet.... didn't have time to figure out what do you think? /vty

[atlas]Probe with static IPv6 can 'lock up' if unreachable on IPv6
by Kenneth Aalberg 11 Jul '11

11 Jul '11

Greetings. As advised by other members of the list, I've moved my probe from behind a router that provided IPv6 tunneling and to the pure IPv4 network. However, when reconfiguring the probe, the static IPv6 address I added to it seems to not 'let go'. It now gets an IPv4 address as it should, but it shows as down in the probe list. The configuration page also claims it still has the static IPv6 address configured. I mentioned earlier about fallback to IPv4, but I'd also like to extend the question towards whether there is any functionality that lets the probe try 'last ditch efforts' to connect in cases where its configuration just doesn't work? (As in, give up on static addresses and try DHCP even if it has been assigned a static address) Best regards, Kenneth Aalberg

[atlas]Falling back to IPv4 if IPv6 connectivity is lost?
by Kenneth Aalberg 11 Jul '11

11 Jul '11

Greetings, Probers. (Yes, that was the first name that came to mind. :P ) I've joined the probecloud, and it is working fine. However, I am on an IPv6 tunnel behind a NAT that doesn't let me configure protocol 41 to be forwarded to one specific host (my linux router). Thus, the AYIYA tunnel is in a NAT table as a normal connection, and will sometimes be cycled out if it is the oldest connection and a new one is attempted, regardless of whether the NAT entry has seen traffic recently or not. The probe receives an IPv6 address, and uses this correctly. However, if the tunnel should go down, the probe will also be marked as down, even if it is actually still alive and can communicate through IPv4. Is there any kind of fallback option to try IPv4 connections before declaring a probe host down? Or would it make more sense for me to disable IPv6 on the probe to ensure it accurately represents the actual state of my connectivity? Best regards, Kenneth Aalberg Probe 737.

Hello, Probe ID 73, it seems to reboot itself after about 1-2 minutes of operation, even though according to tcpdump on the gateway it can successfully communicate with the control DNS, NTP, server, can ping stuff and does receive ping replies. What could be the problem? -- With respect, Roman

[atlas]'Location' sorting for the Public Probes
by Carsten Schiefner 04 Jul '11

04 Jul '11

Hi there, not sure sure whether that's been raised already - but the strictly alphabetical ordering of the probes when 'Location' sorting is activated, doesn't make any reals sense to me; cf. the attached screen shot. Maybe a somewhat greater "intelligence" could be deployed here? I'd suggest the DNS approach: from right to left. :-) Cheers, Carsten -- Homer Simpson meint: http://www.youtube.com/watch?v=Fk0To_o6NxE

[atlas]Atlas probe is "never seen"
by Martin Topholm 02 Jul '11

02 Jul '11

Hi all, I connected the Atlas probe thursday and is is conducting measurements as seen with tcpdump and from the logs on the Atlas site. However the site says the probe is "never seen". How long will it take for the site to register with the probe? Should I reset the probe? Probe ID 776 (near Helsinge, Denmark) -- Best regards, Martin Topholm
