What is Cobbler?

Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.

Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.

What is DNSimple?

DNSimple's origin name servers answer a quarter faster at p90 after erldns work

DNSimple keeps tuning the Erlang stack it now runs end to end. The November 4 post says p90 query time on its origin name servers is down about a quarter, and about a third for DNSSEC queries, with roughly a third less CPU, and record changes now switch in one step so existing records never briefly disappear. It follows October's dns_erlang rewrite, which cut CPU per query by 12%, and the August finish of the migration to fully owned infrastructure. Above that layer sit the CLI launched in May, browser login from June, and Domain Trustee.

Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.

◆ Current state

Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.

◆ Where it's heading

The branch is still gaining features aimed at enterprise data centres rather than winding down: new installer ecosystems in August, directory-backed single sign-on now. Authentication has been a recurring concern since the CVE-2024-47533 admin-API bypass. Releases continue to arrive as rollups from main.

◆ Prediction

Expect further 3.3.x rollups; whether the main line cuts a 3.4 is not visible from these entries.

DNSimple's origin name servers answer a quarter faster at p90 after erldns work

◆ Current state

DNSimple keeps tuning the Erlang stack it now runs end to end. The November 4 post says p90 query time on its origin name servers is down about a quarter, and about a third for DNSSEC queries, with roughly a third less CPU, and record changes now switch in one step so existing records never briefly disappear. It follows October's dns_erlang rewrite, which cut CPU per query by 12%, and the August finish of the migration to fully owned infrastructure. Above that layer sit the CLI launched in May, browser login from June, and Domain Trustee.

◆ Where it's heading

Since owning its full DNS edge, DNSimple has turned to measurable performance work on erldns and dns_erlang, published openly. The product layer above, CLI and API clients, is moving more slowly.

◆ Prediction

Expect more erldns and dns_erlang performance posts; the entries show no sign of a new customer-facing product soon.
