Foundation so Clusev no longer assumes Debian/apt/ufw/systemd. A host's OS is
resolved once (cached) and every package/firewall/service decision asks it.
New app/Support/Os/:
- OsProfile — family + package manager + firewall tool + service manager, plus
supports(feature) returning NULL or a German reason (graceful degradation).
- OsDetector — one unprivileged probe (/etc/os-release + `command -v` with sbin on
PATH + which firewall is RUNNING); family from ID/ID_LIKE cross-checked against
installed binaries; cached 1h (60s when nothing detected). Readability-guards the
`.` source so a host without /etc/os-release still falls back by package manager.
- PackageManager — apt/dnf/zypper command strings (pending count, apply, install,
is-installed); zypper exit 102/103 normalized to success.
- FirewallTool — ufw + firewalld enable/disable. firewalld opens ssh/80/443 in the
PERMANENT config BEFORE the daemon starts filtering (handles running + stopped),
preserving the no-lockout guard for custom SSH ports.
Integration:
- FirewallService enable/disable now OS-aware (ufw or firewalld) with a support gate.
- MaintenanceService: hasApt -> updateSupport(); pendingUpdates() + applyUpgrades()
across managers (dnf check-update exit 100 handled).
- HardeningService: state()/commandFor() per-OS (dpkg vs rpm, ufw vs firewalld, apt
periodic vs dnf-automatic; yum-only hosts gate auto-updates). Each row carries
supported/reason; unsupported features render muted with a German note instead of
a toggle. apply() refuses unsupported features gracefully.
- Server-Details surfaces the detected System / package manager / firewall.
- SystemUpdate modal + view: OS-neutral copy; audit action system.package_upgrade.
Arch (pacman) & Alpine (apk/OpenRC) are detected and gracefully disabled where
unsupported. Debian/ufw/systemd path verified behaviourally identical on the live
fleet. Pint clean; Codex review clean (fixed firewalld lockout + os-release guard +
yum/dual-firewall/zypper edge cases); R12 — 9 routes 200, 0 console errors.

Operator feedback: no way to add servers; irrelevant storage-internals text; fail2ban
only on/off; raw shell commands shown; no apt update/upgrade.
- Add server: CreateServer modal (name, IP/host, SSH port, user, password|key, optional
label) on the Servers index → creates server + encrypted credential ATOMICALLY (DB
transaction). Strict IP/hostname validation (filter_var + hostname; rejects 999.x, ':').
- System updates (Debian/Ubuntu only): MaintenanceService + SystemUpdate modal — shows the
pending-update count (or "unbekannt" when undeterminable) and runs apt update && upgrade
as root; gated to apt hosts.
- fail2ban configuration: Fail2banConfig modal — Sperrdauer / Max. Fehlversuche / Zeitfenster,
written to a Clusev-owned jail.d drop-in (zz-clusev.local, last-wins; never touches the
operator's jail.local/jails). Durations kept verbatim in fail2ban's native grammar
(600, 10m, 1h 30m, -1). Reads the EFFECTIVE [DEFAULT] across files; refuses to save when the
current policy couldn't be read (no overwrite with unseen defaults); reloads fail2ban only
when already active (never starts it).
- Modals: removed the raw "Befehle (als root)" preview + raw stdout dumps from the hardening
modal — clean German description + result only.
- System page: dropped the .env/Datenbank storage-internals callout (irrelevant to the user).
R15 — Codex gate: `codex review --uncommitted` run iteratively; fixed every finding across 9
rounds (fail2ban jail clobbering, section/precedence, composite/-1 durations, reload-starting-
inactive, read-failure propagation, glob exit code, apt-count failure, atomic server create,
IP validation) until clean — 0 security issues throughout. Live-verified on 10.10.90.162;
R12: Servers/Detail/System 200 / 0 console errors, modals open, hardening modal shows no commands.
