netcup-toolbox v0.2.2

Changelog

All notable changes to netcup-toolbox are documented here.

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.
