Voici l’offensive du printemps de CACert

C’est l’#Offensive de printemps: Tous ceux qui n’ont pas besoin de terminer un travail en cours sont invités à #participer à l’Offensive de printemps: Prenez une seule des 72 petites tâches qui attendent d’être achevées depuis des mois, voire des années. Soyez l’un des 72 #héros qui prennent la main et font ainsi avancer #CAcert d’un grand pas!

Behind the scenes …

… we’ve just activated our own OCSP-resolver on our new arm64-servers.

This sounds a little bit unspectacular, but it’s a big milestone while replacing hard- and software within our environment as the old OCSP-resolver-software could not be ported to a recent debian and arm64-environment.

All other critical services (like Nameserver and CRL-Serving) were already moved successfully to our new power-saving machines (2 Raspberry Pi4) in the last weeks/months. OCSP needed some development and testing.

The virtual machines in the old environment are now stopped, within the next days the (power-consuming) sun3-server will then get it’s final shutdown and will be removed from CAcert-Rack during the next visit at the datacenter.

Our main website and signer-software will still be kept running on dedicated servers.

Upcoming Changes for www.cacert.org

Today we switched the connection to our main website as a preparation for a “bigger” change. Unfortunately this (temporary) change is not IPv6-capable, so only IPv4 is working currently.

Over the weekend we plan to move www.cacert.org to another server for a more recent environment and add a second firewall to our rack. During this server-transition you may face some issues while using www.cacert.org, after the weekend the services should be normal again.

Early next week we’ll enable IPv6 again for our main website (maybe by using a new IPv6-Address, but that’s not yet decided).

All other services (like blog/wiki/bugs/…) should remain active as usual as there is currently no planned update.

Froscon 2022

Die FrOSCon (FRee and Open Source CONference) ist eine jährlich stattfindende Konferenz, die von der Hochschule Bonn-Rhein-Sieg und dem FrOSCon e.V. organisiert wird. Die FrOSCon bietet eine Vielzahl von Vorträgen und Workshops zu freier und Open Source Software. Die Veranstaltung findet seit 2006 regelmäßig Ende August statt. Eine große Bandbreite an Referenten verspricht zwei spannende Tage. Die Organisation wird ausschließlich von Freiwilligen übernommen.

Selbstverständlich ist auch CAcert bei der Froscon 2022 mit dabei. Wenn du während einiger Zeit mithilfst, zusammen mit unserem Event-Team den CAcert-Stand zu betreuen, bekommst du natürlich eine Aussteller-Badge und damit auch Zugang zum VIP-Bereich. Bitte melde dich bei events@cacert.org für eine Teilnahme.

Nameserver-Changes for CAcert.org -update-

Update: Nameserver-transition is currently finished, new DNSSEC-records are set and active. KSK and ZSK were replaced by CSK.

In the ongoing process to update hard- and software we’re moving our main domain cacert.org to another master-nameserver-machine (with different nameserver-software) within our rack …

As we’re using DNSSEC to secure our domains, we need to update KSK and ZSK-keys for our domains during this progress, too.

Therefore you may face some DNSSEC-errors or issues in resolving cacert.org-domains within the next days, but this should resolve itself within some hours/days.

As soon as the transition of the nameserver-move is finished, I’ll update this post.

Todo: Give ns1.cacert.org the “old” nameserver-address again (after next hardware-change onsite) so secondary-nameserver ns3.cacert.org can get back to work. ns3 is currently not listed at our registrar, so not active for CAcert-Domains.
