- This is a v1/v2 only release meant to fix stability issues that resulted in stretching the hardware capabilities too far.
- Various fixes for stability and security
- Allow DNS "macros" like $p, $t, $r, which are replaced by the probe each time with probe ID, timestamp and a random value, respectively
- Add SNI support to TLS/SSL checks
- Add option to embed probe ID in ping requests in order to filter out RIPE Atlas generated ICMPs
- Report time-to-complete in TLS/SSL results even if fetching the actual certificate fails
- Fixed a bug where there were no results delivered for DNS measurements with the "include the abuf" option turned off
- Fixed a regression where DNS measurements using TCP transport always failed
- Fixed a bug where WiFi measurements could sometimes report using the wrong outgoing network interface
- Changes to use USB sticks (in v3 probes) as little as possible by buffering results in memory. As a tradeoff for more expected stability, the probes lose recent, unreported measurement results (ie. the ones collected in the last 60-90 seconds).
- Unexpectedly terminated TCP connections caused SIGPIPE signals crashing the measurement the process
- Various stability and security fixes to the measurement code
- First release of wifi firmware (4755)
- Various security/stability fixes in the measurement code
- Disallow measurements towards 0.0.0.0/8

- Probes will soon start reporting their uptime in a new "virtual measurement", ID 7001
- Fixed an error case where results of one-off traceroutes could have interfered with ongoing traceroutes
- Added preliminary support for specifying a timeout parameter for DNS measurements
- The method for measuring times (e.g. RTTs) for each measurement has been switched to use a strictly monotonic, relative clock, thereby avoiding the artefacts caused by absolute clock changes due to time synchronisation.
- The RDATA field of a DNS measurement result (in response to a TXT query) is now a list of strings. It was a single string before.
- The cipher list supported by SSL/TLS certificate checks have been refreshed.
- Fixed a bug where one-off results were reported multiple times in some cases.
- Fixed a issue where NTP measurements could generate syntactically incorrect results which, as a consequence, were never stored.
- Fixed an issue where IPv6-only probes did not properly report their network configuration.
- Fixed a bug where failed DNS measurements in some cases did not report the time of measurement.
- The probes, in addition to the infrastructure, now also enforce the restriction that local (RFC1918 and link-local) addresses should not be measured.
- When removing static configuration from a probe, the statically added previous DNS server was still used
- This is mostly a maintenance release, with internal behavioural changes only.
- This firmware incorporates a few bug fixes:
- If probe has statically configured nameserver and also DHCPv4, the DHCP one wins, thereby fixing stale DNS entries
- Enhance the NTP client on v3 probes
- V3 probes now pick up IPv6 DNS resolvers from RA messages
- Stability issues on v1/v2 probes when HTTP measurements immediately fail with connection errors
- "SSLCert" measurements now also support TLS
- Fixed two bugs in ping measurements where the probe had issues pinging its own IPv6 address
- Fixed wrong host header for IPv6 literals in http measurements
- Probes are now trying to avoid starting too many measurements at exactly the same second
- Bugfix: fixed a bug in paris traceroute where the ICMP version would have the wrong paris id in outgoing packets
- Bugfix: fixed a memory leak in the DNS measurements code
- Enhancement: include a cookie in outgoing ping packets and check the reply
- Enhancement: in ping, report IP version and target address even if socket connect fails
- Experimental suport for NTP measurements (not publicly available yet)
- Ping interval option (-i option, needs support from API and UI)
- The "lts" field is now also available in the output of traceroute, dns, sslgetcert, httpget
- Traceroute IPv6 extra error code 'h': destination unreachable/beyond scope
- Fixed error in the output of traceroute
- Fixed bug in parsing multiple IPv6 extension headers in traceroute
- Fixed bug in DNS where RA flag was set in requests
- The new firmware fixes a few DNS related bugs:
- In some cases the probe sent DNS results too often
- Querying the local DNS resolver could result in multiple results (one per resolver), but these could not be accessed in the data store. The new version collects results from all resolvers into one data structure. See the /apis/result-format/#version-4610-dns-lookup for details.
- In addition, this firmware adds preliminary support for using IPv6 extension headers. This will be available in the UI and in the API at a later date.
- The new firmware release (4600) contains bug fixes for missing fields in ping results (TTL and source address). It also incorporates a more secure way for the probes to authenticate new firmwares before upgrading.
- Due to an issue with the latest firmware release, a subset of the v3 probes were listening to incoming connections on an open port that should not have been left open. As a secondary measure, however, access to this port required credentials only available to the RIPE Atlas probe developers. It therefore never presented open access to the probes. This port (SSH) is used for development purposes in our internal development environment.
- We upgraded the v3 probes to a new, corrected firmware version (4580), and improved the checks in our firmware release process. The new firmware is otherwise functionally equivalent to the previous one.
- This issue did not affect version 1/2 probes and anchors.
- Upgrade kernel on v3 probes without losing static network config
- Uniform interpretation of the size parameter of ping and traceroute: the size excludes the IPv4/IPv6 header and the transport (ICMP, TCP, UDP) header
- Add TCP mode to traceroute measurements
- Most measurements (except for DNS "use probe's local resolvers") now pick up a new list of resolvers if it has been updated by DHCP
- Support for SRV and NAPTR in DNS measurements
- Support "number of retries" option in DNS measurements
- Note that the use of the new measurement flag will be enabled in the UI and API at a later stage.
- This is a bug fix release for all probe architectures. There is a small bug in the probe measurement code that can be trigger only if a controller sends the wrong commands to a probe.
- Version 3 probes * Fixes for static network configuration
- Anchor * Cleanup in anchor package * Various fixes to the startup/shutdown scripts * Aligned build script with upstart for killing processes * Clean up pid files on Atlas shutdown * Kill Atlas processes on install/uninstall * Anchor now requires daemontools to be installed
- RIPE Atlas probe software now supports two more architectures: TP-Link (for the next generation probes) and CentOS (for RIPE Atlas anchors).
- There is now support for one-off measurements for ping, traceroute, DNS, and HTTPget.
- We fixed a bug in DNS measurements in which, when querying local resolvers, more queries went to the last resolver.
- Fixed "error" : { "TUCONNECT" : "Success"}. Before this version DNS TCP and HTTPget reported an error message "Success".
- First release of anchor package
- Fixed bug in traceroute when it has to deal with rfc4884 objects (mpls) that have a wrong size.
- Delayed DNS name resolution in ping and traceroute. This feature will soon be enabled through the UI.
- Fixed bug in HTTP GET where some characters where not properly escaped in generating the result JSON.
- Fixed bugs in the libevent stub resolver to better handle DNS errors and timeouts (affects mostly httpget)
- Limit the amount of measurement data that is sent as one unit. This prevents probes that have not connected to a controller for some time from overloading the controller.
- The probe uptime is now in the DNS SOS messages that are sent by probes before they try to connect. This will allow making a distinction between various reasons for disconnects: e.g. probe reboot vs. network problems.
- Initial version for anchor package added (Anand Buddhev)
- This firmware fixes two bugs. * The first one is that DNS results may get mixed up when a probe runs two DNS measurements at the same time. * The second one is where traceroute sometimes reports a timestamp of 0.
- In addition, the firmware now has IPv6 literals for the registrations servers, so an IPv6-only probe can connect to a registration server even if it doesn't have a DNS resolver.
- The main new feature in this firmware is the use of libevent and rewriting the measurement code to use it. This provides a much higher capacity for doing measurements. In addition, the probe now reports results in JSON. Expect the traceroute output to be completely different. The are a number of small changes. For example, the DHCP client now sets the client-id and vendor class. Please note that if you have given the probe a static IPv4 address through DHCP and the probes stops working then this may be caused by the change in DHCP client-id.
- This firmware contains a number of small fixes that deal with exceptional conditions. Probes should also reconnected slightly quicker after a disconnect.
- More pings to fixed destinations
- Traceroutes to fixed destinations
- DNS root server anycast instance checks
- We're in the process of rolling out a new firmware version. It enables a new feature that has been asked by members of the community: /howtos/probe-static-network-config.md. Using the UI, one can ask the probe to try to use static IPv4/IPv6 addresses (and DNS resolvers). If these settings don't work, the probes will fall back to using DHCP. As a byproduct, this feature also allows IPv6-only deployments.
- The new firmware version enables the use of a second registration server (woolsey.atlas.ripe.net). All probes are expected to upgrade automatically in the coming days.
