How can I reduce data usage on remote satellite-connected islands?
by chris＠gare.co.uk 09 Sep '20

09 Sep '20

Hello all, I've just become an ambassador for the RIPE Atlas programme. I have a question. I wish to deploy a number of probes to remote low-capacity satellite connected islands. These islands have strict and VERY expensive monthly usage quotas. Looking at some probes already installed, I see that the minimum bandwidth (is that the term used?) is approximately 3.3kbit/s This equates to around 1GB of data per month which represent a significant percentage of a consumer's monthly quota. I'll have a hard job convincing volunteers to act as hosts if they consume that much. Is there a way I can set 'bandwidth' to less than 10kbs or is there a workaround I can use to reduce this under my control? It has been suggested that I could out a timer on the host but that is nonworkable! Any help would be appreciated as I know that reachability is quite unreliable at times and the data I could provide would be most interesting. Chris

Extreme slowness today?

23 minutes before Atlas tells me there is no suitable probes with my criteria (country=SD, which does not surprise me). Same slowness for all measurements.

Disabling TLS 1.0 and 1.1 on RIPE Atlas anchors
by Robert Kisteleki 01 Sep '20

01 Sep '20

Dear RIPE Atlas users, We received reports that the availability of TLS 1.0 and 1.1 on RIPE Atlas anchors triggers some security alarms for some anchor hosts. Since the anchors don't host anything sensitive, and the measurment code is not expected to be affected by this, we will stop supporting these protocols on the anchors (*) as of *1 September*. We'll carry on with supporting TLS 1.2 (*) the RIPE Atlas website/UI will be unchanged for the time being although we expect similar changes in the near future Regards, Robert Kisteleki RIPE NCC

Re: [atlas] [RIPE-NCC/ripe-atlas-software-probe] Software probes only connect to one controller? (#45)

Those controllers are kept separate from controllers for hardware probes. We placed both controllers at Hetzner and unfortunately, Hetzner seems to have some issues recently (or at least more than I remember).

It seems that the issue at Hetzner was less than 2 hours. However, with all controllers for software probes at Hetzner, a long failure at Hetzner would indeed impact all software probes. In this case, why not have the software probes set up with a fall-back RIPE Atlas Anchor (controller)? E.g. - Setup a list of 2 or more Anchors in a hierarchical order, - If the software probe cannot reach the primary Anchor for more than 10-20 minutes., fall-back to the next Anchor reachable, - Retest connectivity to all configured anchors every 6 hours, - Revert to use the first reachable anchor in the locally configured list (a hierarchical order). * The above idea assumes an Anchor being able to temp. handle more than the default ~500 probes per Anchor, plus co-location diversity of >= 2 providers and >= 3 anchors. -- Chriztoffer

Far remote probe 34512 offline but partially works
by ripe＠brite.cz 27 Jul '20

27 Jul '20

Hi team, I have probe 34512 in distant location [not able to have it checked physically for some more time], it shows offline since 2020-07-21, no SOS messages listed since 2020-05-16. But other devices connected to the same router do work online, and also the router keeps sending me Log Messages via internet so its internet connection has to be working fine. Router log shows DHCP request getting from the Probe every 12 hours, as usually: 2020/07/27 18:51:44 Info 93-153-42-167.customers.tmcz.cz daemon dnsmasq-dhcp DHCPACK(eth1) 192.168.222.220 c0:25:e9:a8:57:96 2020/07/27 18:51:44 Info 93-153-42-167.customers.tmcz.cz daemon dnsmasq-dhcp DHCPREQUEST(eth1) 192.168.222.220 c0:25:e9:a8:57:96 The router itself is behind NAT and I'm not able to remote to it and proceed with further investigation. From the Log above I see the Probe is running and keeps requesting DHCP requests as usually, so not sure how it could show offline. Do you have any further logs or a way how to try to resurrect the Probe remotely? Thank you Jiri

probe offline/lock up
by Bryan Fields 06 Jul '20

06 Jul '20

I had an interesting alert yesterday, as my probe 54858 said it was offline. I was unable to ping it from the router port it's directly connected to, but did some some traffic on the port via the counters. There was a fresh ARP entry as well. I power cycled it and it came back online. I was then able to ping it via v4 after it DHCP'd it's address. v6 pings were working to it's SLAAC address too. It has not gone offline now, but I am noticing pings on v4 are not working at all again. v6 seems unaffected. Is this normal or is there a problem with my probe? I've never really taken this close of a look before, I'm unsure if it has an issue or if this is normal. Thanks, -- Bryan Fields 727-409-1194 - Voice http://bryanfields.net

Unauthorised probe transfers
by Paul Eagles 24 Jun '20

24 Jun '20

Hello, I've just had 2 emails saying that 2 of my software probes (numbers 1000305 & 1000137) have been transferred to LeaseWeb NOC. Both these probes (and another) live on LeaseWeb VPSs (one in NL, one in USA) but I haven't started or authorised a transfer. Before I go and shout at then, how could this have happened? Checking in 'My Atlas' it does indeed no longer show these as being my problems. Why would the good people at RIPE allow transfer of 2 of my probes without my approval? Yours, Paul.

dead v1 probe
by Gert Doering 22 Jun '20

22 Jun '20

Hi, have there been software updates for v1 probes recently? I've heard about a few v1 probes that have died "just last week" - mine among them (#461), fell off the net with "Firewall Problems Suspected", but it's no longer even ARPing properly (= either it totally lost its config and wants DHCP now, which there isn't in this network, or it just died)... So knowing whether this is a more widespread issue and possible reasons would help me to decide how much effort to invest in debugging this. gert -- have you enabled IPv6 on something today...?

Turris SW probe - long time to connect
by Jan Pavlinec 04 Jun '20

04 Jun '20

Hello, Since this week based on report [1], [2] from Martin we were able to observe his issue, which he reported and by using Atlas SW Probe 5010 and older, we noticed that in CLI probe is running and that it is doing something, but on the RIPE website, it shows that probe is disconnected. Can you please check probes IDs (1000585, 1000243) and what it took so long to show that it is connected? Both of those probes were shown as connected at the same time - 20:22) on Tuesday? We noticed that in some cases if you were using the latest version 5020 and register a new probe, it is working within a few minutes. However, we pushed to all our Turris OS version updated Atlas SW Probe to version 5020 and some of our users noticed similar maybe the same behavior. A probe was running on the router, but it was disconnected for almost an hour (probe ID 1000036) The router is working in all cases, ping, dig connection is OK. I'm wondering if this issue isn't on server side. In reg_init_reply.txt were following data: WAIT TIMEOUT 115 Do you know how to debug it more?

anchor on a /32 network with on-link routing ?
by Matthieu Herrb 24 May '20

24 May '20

Hi, here at Tetaneutral.net we purchased an anchor with the idea to host it in our network. For IPv4 We are using /32 addresses everywhere, and do the routing by setting the 'on-link' flag on the default route. This configuration doesn't seem to be possible through the management interface. It complains that the gateway is not no the same network as the host and provides no way (as far as I can tell) to setup the 'on-link' flag. Apart from inserting another router in front of our anchor to let it use a narrower prefix, is there a way to set it up ? Or can this be considered for the future evolutions of the anchor software ? Thanks in advance. -- Matthieu Herrb

Software probe using port 8080

Hi, Is there any way to change the ports that the software probes use? Port 8080 is used by the probe which conflicts with another piece of software I wanted to use. Looking in the processes I saw this: atlas 843 0.0 0.2 50348 5992 ? S 10:15 0:00 /usr/bin/ssh -o ServerAliveInterval 60 -o StrictHostKeyChecking yes -o UserKnownHostsFile /var/atlas-probe/.ssh/known_hosts -R 50948:127.0.0.1:2023 -L 8080:127.0.0.1:8080 -i /var/atlas-probe/etc/probe_key -p 443 atlas(a)ctr-fsn01.atlas.ripe.net KEEP I had to kill the PID in order to run the other software I need so at present this new software probe is down. I'd like to start it up again but can't unless I can control which port the SSH tunnel is using. Thanks, Pauil.

Software probes offline since updating to 5010-3
by Paul Eagles 12 Mar '20

12 Mar '20

Hi all, About an hour ago I updated my 4 software probes (1000136, 1000137, 1000149 & 1000177) to 5010-3 from 5010-1 and they're all still showing as offline. For each probe I went through and updated the keys within a minute or so of the installation finishing so I don't think that's the problem. It shouldn't be an internet connection issue, they're all using the same connection as they were prior to the update and prior to the update all 4 probes were connected OK. Plus I have a physical probe at home in the same location as one of the software probes and that physical probe is showing as online. One of the software probes has been rebooted but that didn't seem to make any difference. Checking the running processes on the host everything appears OK, I see 2 instances of the ATLAS binary running. Am I missing something or just being impatient? Cheers, Paul.

Broken traffic graphs in latest firmware (5010)
by Philip Homburg 10 Mar '20

Hi, A change in the RIPE Atlas probe code to make reporting traffic statistics optional in software probes (and disabled by default) has the unfortunate side-effect that reporting of traffic statistics is now disabled on Version 3 and Version 4 hardware probes, as well as all anchors. This change was rolled out in firmware version 5010. Unfortunately, this effect was not spotted during testing. We will roll out a new firmware release that corrects this issue in coming weeks.

Dear colleagues, Over the past month there have been issues with the "system-ipv[45]-stable-{1,30,90}d" tags, which were not applied to many of the probes that should have had them. This was caused by accidental data format changes from a backend migration. The issue should now be fixed, so probes will have the correct tags applied. If you notice any persisting issues then please let us know! Apologies for any inconvenience. Kind regards, Chris

atlas probe down
by MAYER Hans 19 Feb '20

19 Feb '20

Dear All, Our Atlas probe with ID 35603 is down since Wednesday exactly 12:00 LT. I unplugged power and powered on, but no success. After power on some LED's are blinking. Finally the power LED stays on and the LED next to it is blinking. But I can't ping this probe. Either on IPv4 nor on IPv6. We got this probe in summer 2018. So I can't believe it's EOL. Any ideas what I can do ? Kind regards Hans --

Can I issue a traceroute measurement with multiple targets?
by Vasileios Giotsas 11 Feb '20

11 Feb '20

If I have 100 IPs to target from a single probe, is it possible to create a single measurement with 100 targets similar to how I'd do if I wanted to target a single IP from 100 probes? I've read through the Atlas API documentation and couldn't find anything like that but it looks like some of the built-in measurements do that. Thanks, Vasilis

Atlas API stream broken?
by Teun Vink 10 Feb '20

10 Feb '20

Hi, Since ~13.30h CET this afternoon our Atlas data stream subscriptions (using the ripe.atlas.cousteau python library) stopped receiving updates. Earlier today we (at 11.27h) observed some issues with the backend where we received redis errors, which were resolved at ~12.09h CET. I heard these were related to some firewall issues, could these problem be related? Regards, -- Teun Vink BIT | teun(a)bit.nl | +31 318 648 688 KvK: 09090351 | GPG: 0xFC8B25D6 | RIPE: TEUN-RIPE

Graphs and measurements are scaled by a factor of 1000
by Enrico Ardizzoni 07 Feb '20

07 Feb '20

Starting from 06/02/2020 at 6.00 AM UTC all graphs and measurements are scaled by a factor of 1000. Something went wrong on probes backend... "An error occurred while retrieving measurement data. We apologise and do our best to fix it asap!"

Planned Atlas downtime on 29 January
by Robert Kisteleki 06 Feb '20

06 Feb '20

Dear RIPE Atlas users, Please be aware that we plan to do maintenance work in the RIPE Atlas core infrastructure two weeks from now, on Wednesday 29 January, between 9:00-12:00 CET (Amsterdam time). The RIPE Atlas website, UI and API will be unavailable in this period. The probes should remain connected and results will be collected normally, although during this period they can only be accessed real-time via the streaming service. Apologies for the inconvenience this may cause. Regards, Robert Kisteleki

Using Atlas for Monitoring of Anycast DNS
by Klaus Darilion 20 Jan '20

20 Jan '20

Hello! I want to restart this old thread and ask for available tools. For our Anycast DNS cloud, I want to measure the "performance", ie the RTT from Atlas probes. 1. Create measurements (I can do that already ;-) 2. Analyze this measurements: - fetch measurement - analyze the probe locations (ie. country, continent) - create reports with average RTT from certain countries and continents This second step I have partly in old scripts using influxdb and grafana dashboard - but that was a proof of concept with bad code. So, before starting coding from the base - are there some available scripts which can do the second part? Is https://github.com/RIPE-NCC/ripe.atlas.sagan still the way to go for measurement processing or are there meanwhile some better/smarter libraries? ie something for php?
