netcup-toolbox v0.4.0

Changelog

All notable changes to netcup-toolbox are documented here.

0.4.0 - 2026-11-08

Added

• tools/netcup-mail-check.sh: MX, SPF, DMARC, DKIM, PTR, and port 25 checks
  with human and JSON output.
• tools/netcup-exporter.sh: Prometheus textfile metrics for uptime, load,
  memory, disk, BBR, CPU steal, and Netcup latency.

0.3.0 - 2026-11-07

Added

• tools/netcup-rdns.sh: IPv4/IPv6 PTR management via the SCP REST API, including
  OAuth2 device-flow login, token rotation, --dry-run, and --json.
• tools/netcup-snapshot.sh: SCP snapshot list/create/delete/restore/export with
  task polling, --dry-run, and explicit --yes guards for destructive actions.
• tools/netcup-ping.sh: --json, --csv, --count, --timeout,
  --no-color, and --fail-on-timeout for automation.
• tools/netcup-calc.sh: --json, --plan, --help, and --version;
  locale-independent decimal formatting.
• tools/netcup-init.sh: --force escape hatch when the SSH listener cannot be
  verified; the default now fails closed instead of enabling UFW blindly.
• tools/netcup-vlan.sh: auto-detects netplan vs ifupdown, validates the
  interface and the required network tools before --apply.
• data/datacenters.json with official test IPs, regions, and verification dates.
• data/meta.json with schema version, generation timestamp, availability date, and dataset counts.
• Release archives (netcup-toolbox-<tag>.tar.gz) with detached checksums, built by the tag workflow.
• German Black Week / Advent Calendar 2026 section in README.md.
• Issue/PR templates, Dependabot, and a release workflow are included. A Debian/Ubuntu/Alpine CI matrix is planned.

Fixed

• Public catalog now includes availability and availabilityCheckedAt; sold-out GPU plans are labelled and no longer receive a claim CTA.
• README.md release verification now uses the release archive, so sha256sum -c works outside a full checkout.
• The public README no longer calls official test IPs "looking glass nodes".
• Added the missing 20% AT gross price column.

0.2.5 - 2026-10-31

Changed

• Webhosting promo wording aligned with Netcup's "monthly price reduction":
  "30% Monthly Discount" instead of "permanent/lifetime".
• The 1-month Webhosting NUE promo uses the same monthly discount wording.

0.2.4 - 2026-10-31

Changed

• Added the separate VPS pico G11.5s plan (1 vCore, 1 GB RAM, 30 GB SSD,
  EUR 2.21 gross for the 12-month term).
• ARM, VPS pico and VPS nano are marked as voucher-ineligible, matching the
  Netcup cart message: vouchers cannot be redeemed for VPS ARM or VPS Lite.
• Webhosting partner labels now say "30% monthly discount" instead of
  "lifetime", matching Netcup's "monthly price reduction" wording.
• Contract term is included in the public data/servers.json.

0.2.3 - 2026-10-31

Fixed

• Corrected VPS 1000 ARM G12.5 to 4 ARM64 vCores, 128 GB NVMe and the
  official EUR 14.50 gross base.
• Replaced the combined "piko / nano" row with the official VPS nano G11.5s
  (2 vCores, 2 GB RAM, 60 GB SSD, EUR 3.69 gross for the 6-month term).
• Added the minimum contract term to data/servers.json.

0.2.2 - 2026-10-31

Fixed

• vGPU catalogue prices now match the official Netcup cards: RS 2000 vGPU 7
  starts at EUR 121.77 gross, RS 4000 vGPU 14 at EUR 232.43 gross.
• Webhosting 2000/4000/8000 use the exact net base so the calculated gross
  price matches Netcup's EUR 4.03/8.10/13.17.
• The calculator self-test now asserts the official Webhosting 4000 value
  (EUR 8.10), not the previous EUR 8.11.

0.2.1 - 2026-10-31

Fixed

• netcup-init.sh detects an IPv6-only SSH listener via /proc/net/tcp6 and
  reads the distribution/codename from /etc/os-release instead of relying on
  lsb_release.
• The public data/servers.json no longer contains voucher series prefixes;
  only the reusable universal code is published.

0.2.0 - 2026-10-31

Fixed

• netcup-calc.sh now uses Netcup's ceiling rounding rule for VAT instead of
  half-up rounding. Example: RS 500 G12.5 at 19% DE is EUR 12.93, not EUR 12.92.
• netcup-vlan.sh now defaults to MTU 1500 and rejects jumbo frames, matching
  Netcup Cloud vLAN. The site's VLAN generator uses the same value.
• netcup-ping.sh now parses both iputils and BusyBox ping summaries. The
  duplicate root-level netcup-ping.sh was removed.
• netcup-dns-sync.sh now checks every API status, validates the detected
  public IPv4 address, refuses to guess between multiple A records, and
  preserves the full DNS record object in updateDnsRecords.
• netcup-init.sh no longer runs a full system upgrade by default, supports a
  custom SSH port, verifies that SSH is listening before enabling UFW, and
  supports --dry-run. The Docker/UFW bypass is documented.

Changed

• Single-use voucher codes are no longer published in the README. The
  repository lists the reusable new-customer code and links to the site's
  dispenser, so a reader cannot burn a one-time code before a visitor claims it.
• Data files are generated from the site catalog. data/benchmarks.json is
  labelled as an aggregated extract, not raw YABS logs.
• README commands are pinned to a release tag instead of main.
• Added CI (shellcheck, syntax checks, self-tests, JSON validation, checksums),
  SECURITY.md, and release checksums.

0.1.0 - 2026-10-30

• Initial public release: ping, init, vLAN, DDNS, and VAT calculator scripts;
  server and benchmark datasets.
