The server-detail page gains a "Firewall-Regeln" panel — addressing "ich kann nur
aktivieren, sonst nichts": list rules, add, and delete, with hard SSH-lockout guards.
FirewallService:
- status(): one privileged read — installed/active, default policies, and the rule
list. ufw rules come from `ufw show added` (add-syntax, works active OR inactive),
defaults from /etc/default/ufw; a CLUSEV_FWREAD_OK sentinel + a "Status:" check
distinguish a real read from a failed/empty one.
- addRule(): validated action/proto/port/from (proto before `from`, ufw grammar);
refuses deny/reject on the SSH port or portless (would block all inbound).
- deleteRule(): whitelists the spec against rules ufw actually reported (injection-
proof — a forged spec can't match), deletes by spec (race-free, no rule number),
guards SSH-port allow rules incl. ranges and trailing comments, distinguishes
not_found from a real deletion so the audit only records true deletions.
firewalld is READ-ONLY this release: status() reads the runtime state of every active
zone (ports/services/rich rules, zone-attributed), rule mutation is refused with a
German note. on/off + hardening (Phase A) still work.
UI: x-panel with default-policy badges, "+ Regel" (modal modals.firewall-rule), per-
rule delete via R5 ConfirmAction (audit deferred to the real outcome), graceful
read-error / not-installed / inactive / firewalld-read-only states.
Fix: the firewall row's tone variable was renamed $tone -> $ruleTone — the page-level
$tone is a closure used by the gauges/Volumes panel; reusing the name clobbered it and
500'd the page below the firewall block. R12 now confirms the full loaded page.
Default-policy EDITING was intentionally not exposed (highest lockout risk).
Pint clean; Codex review clean; R12 — server-detail HTTP 200, 0 console errors,
firewall panel + rules + volumes all render.

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.

Rework the server-hardening UX per operator feedback ("only activate, can't
deactivate or adjust, UFW won't even activate, is the existing state read?").
- Bidirectional toggles: each item (SSH root-login, SSH password-login, fail2ban,
UFW, unattended-upgrades) is a clean Aktivieren/Deaktivieren toggle driven by the
live feature state, not a one-shot "Anwenden".
- Real state read (HardeningService::state, privileged): SSH from `sshd -T` (the
EFFECTIVE config — honours Include order + Match blocks), UFW from `ufw status`,
unattended from `apt-config dump` (effective periodic value), packages via dpkg —
so nicht-installiert / inaktiv / aktiv are detected; a feature counts as "secure"
only when installed AND active.
- UFW activation installs ufw if missing (fixes "ufw: not found"); opens the detected
sshd port + 80/443 before `ufw --force enable`; adds disable().
- SSH drop-in renamed 00-clusev.conf (sorts + wins first); apt periodic written to a
last-winning 99zz-clusev file. Long timeout for apt installs.
- preview() returns the EXACT command apply() runs (single source — no drift between
the confirmation preview and the executed mutation). Password-disable lock-out guard
intact (refused when Clusev uses password auth or no key exists).
R15 — Codex review gate: `codex review --uncommitted` run iteratively; fixed every
finding across 5 rounds (drop-in precedence, apt periodic config, preview/apply drift,
ufw status detection, privileged-read error handling, stale-config secure state) until
"no actionable regressions". 0 security issues throughout.
Live-verified on 10.10.90.162: state via sshd -T (effective), fail2ban + unattended
toggled on/off both ways, ufw installed + state reflects, lock-out guard refuses
disabling password auth. R12: server detail 200 / 0 console errors, toggles render.

Security pivot — make server hardening, SSH access, firewall, dashboard domain/TLS
and the release channel controllable from the dashboard (no SSH needed), with guards
so a remote change can never lock the operator out.
Foundation
- ssh_credentials gains name + disabled_at + last_used_at; CredentialVault refuses a
disabled credential. New key/value Setting model. FleetService::runPrivileged() /
runPlain() — central sudo-aware exec (base64-wrapped sh -c), live-verified as root.
A · control-plane self-hardening
- SecurityHeaders middleware: env-aware CSP (allows the Vite dev origin in dev, strict
same-origin in prod), X-Frame-Options DENY, nosniff, Referrer/Permissions-Policy,
HSTS when secure. 2FA brute-force throttle (5/60s). install.sh sets
SESSION_SAME_SITE=strict + EXPIRE_ON_CLOSE + SECURE_COOKIE (only behind TLS).
B · SSH credential management
- name/label on the access; a credential card on the server page with Bearbeiten /
Sperren-Entsperren (kill-switch) / Löschen (R5), all audited.
C · server hardening from the dashboard (guards + confirmation)
- HardeningService (PermitRootLogin no, PasswordAuthentication no, fail2ban,
unattended-upgrades) + FirewallService (UFW). HardeningAction modal previews the
exact root commands before applying. GUARDS: refuse to disable password-login when
Clusev itself logs in by password or no key exists; UFW opens the real sshd port +
80/443 before enabling. Live-verified non-destructively (previews, the password
guard refusing, ufw status read).
D+E · System page (/system)
- Dashboard Domain + Let's-Encrypt email (Setting) -> DeploymentService renders the
matching Caddy site block (honest: stages the file + shows the reload command, never
fakes TLS). Release channel (stable|beta|dev) configurable; Versions reads it.
Built largely by 4 parallel agents into disjoint files; shared files integrated + the
security-critical bits hardened by hand (the password-auth lock-out guard + env-aware CSP).
Verified (R12): /system + server detail + all 8 routes 200 / 0 console errors (CSP does
not break Livewire/Alpine/Vite); credential card + 5 hardening "Anwenden" buttons render;
the hardening modal opens with the command preview; System persists domain/channel +
renders valid Caddy config; runPrivileged runs as root + the vault refuses disabled creds.
