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.
