Amir Alexander Abdelbaki c1e54f4f75 feat(freeipa-ansible): add CheckMK monitoring for Proxmox VE + PBS
Proxmox VE hypervisors and Proxmox Backup Server aren't FreeIPA clients,
so they sit outside the dev_mon_base host-group flow. Add standalone
CheckMK local checks (cluster/storage/guests/backup for PVE; datastore
usage/last-backup/task-failures for PBS) plus a small installer that
detects the role, installs the agent, and registers the host under
/ansipa/infra — mirroring the existing dev_mon.sh pattern without
requiring IPA enrollment.

Amir Alexander Abdelbaki 4f22a3b03f refactor(ansipa): dev_security-scan → dev_mon_clamscan, report to CheckMK; drop SMB scan pipeline
Rename the security-scan policy to dev_mon_clamscan (fits the XXX_mon_* naming
for monitoring groups) and make it hand results to CheckMK natively instead of
uploading logs to an SMB share.

- dev_mon_clamscan.sh: runs the daily ClamAV/rkhunter/chkrootkit scan and writes
  its own CheckMK local check (ansipa_clamscan → service "Ansipa_ClamScan"); the
  agent from dev_mon_base collects it. Removes the SMB upload entirely. Discovery
  matches dev_mon_clamscan BEFORE the generic dev_mon_* catch-all so it sets
  WANT_CLAMSCAN rather than being treated as a dev_mon.sh check. mkdir -p the
  cron dir (minimal hosts lack /etc/cron.d until cron is installed).
- Remove the now-redundant dev_mon_malware check from dev_mon.sh (subsumed).
- Remove usr_scan-notify and the whole SMB scan-alert pipeline it fed:
  ansipa-fetch-alerts.sh, ansipa-scan-notify.sh, server ansipa-check-scans.sh,
  the ansipa-scans Samba share + scanupload account, /etc/ansipa-smb.creds, and
  the SMB_SCAN_PASSWORD/smb_scan_password variables (playbook, compose, run.sh,
  .env, Dockerfile). The ansipa-luks-keys and ansipa-policystore shares stay.

Verified live on the Arch client: enrolling in dev_mon_clamscan writes the scan
script, cron, and local check (which reports "Ansipa_ClamScan"); leaving the
group removes all three. Docs updated (policy tables, architecture, SMB shares,
scan-flow → CheckMK).

Amir Alexander Abdelbaki adea0f457d fix(ansipa): reliable nginx + keycloak healthchecks
Both containers were reporting "unhealthy" while serving fine — the
healthchecks I added probed the wrong address/endpoint:

- nginx: `wget localhost` resolves to IPv6 ::1 inside the container, but nginx
  listens on IPv4 0.0.0.0:80 only, so the probe was refused. Use 127.0.0.1.
- keycloak: with KC_HTTP_RELATIVE_PATH=/auth, /health/ready on the 9000
  management port returns 404. Probe /auth/realms/master on the serving port
  8080 instead (bash /dev/tcp — the image has no curl/wget).

Verified all five containers report healthy and the gateway serves /, /ipa/ui/,
/cmk/ and /auth/ correctly.

Amir Alexander Abdelbaki be757fda5a feat(ansipa): nginx gateway — reverse proxy + portal start-page
Add an nginx service that fronts all three web UIs on a single hostname/port
and serves a portal landing page, designed to sit behind the operator's own
TLS-terminating reverse proxy.

- Each backend is proxied at the path it already serves natively — FreeIPA
  /ipa, CheckMK /cmk, Keycloak under a configured /auth relative path — so no
  fragile path rewriting is needed and one upstream proxy line exposes
  everything. FreeIPA's strict Host/Referer anti-CSRF checks are satisfied by
  pinning Host to the IPA hostname and rewriting Referer.
- Honors incoming X-Forwarded-Proto/For so it works behind a second reverse
  proxy (double-proxy verified: portal, FreeIPA, CheckMK and Keycloak all
  reachable through two layers, and a CheckMK login POST completes to an
  authenticated session through the gateway).
- Keycloak: KC_HTTP_RELATIVE_PATH=/auth + KC_PROXY_HEADERS=xforwarded so it
  builds correct URLs behind the gateway; deliberately not forwarding
  X-Forwarded-Port (this gateway is :80 internally; the public port is the
  upstream proxy's) to avoid https://host:80 redirects.
- .env.example documents ANSIPA_HTTP_PORT and gives the exact upstream
  reverse-proxy snippet (nginx location block + Caddy one-liner).

Portal is a static cyberqueer-themed page linking to /ipa/ui/, /cmk/, /auth/.

Amir Alexander Abdelbaki b21f415cde fix(ansipa): hostname-binary-free FQDN + push-mode orchestration (NAT path)
Found while running the policy matrix and NAT/WAN scenario in VMs:

- ansipa-enforce-policies.sh and the dev_security-scan generated script called
  `hostname -f`, but the hostname binary (inetutils) is not installed on a
  minimal Arch system, so the enforcer aborted with "hostname: command not
  found" on every run. Add an ansipa_fqdn() helper (hostnamectl / getent /
  /etc/hostname / kernel-hostname fallback chain) and use it; inline the same
  fallback in the standalone scan script.

- Fix two stacked bugs that meant CheckMK push mode — the only monitoring
  transport that works when a client is behind NAT — never functioned:
  * ansipa-checkmk-setup.sh referenced IPA_ADMIN_PASS in the DONE_FLAG
    early-exit path, but that variable was assigned only afterwards, so every
    rerun kinit'd with an empty password, failed silently, and skipped the
    push-mode request writer. Resolve config before the early exit.
  * _write_push_requests parsed `ipa hostgroup-show dev_mon_base` members with
    awk that did `next` on the "Member hosts:" line — but ipa prints members on
    that same line, so the only line with hostnames was discarded and no push
    request was ever written. Rewrite the awk to capture the label line's value
    plus wrapped continuation lines. Verified end-to-end: requests are written
    and CheckMK flips the host to cmk_agent_connection=push-agent.

Amir Alexander Abdelbaki 0f767fb051 fix(ansipa): docker stack volume/network naming, healthchecks, client-routable CMK URL
Found while bringing up the FreeIPA+CheckMK+Keycloak stack in a VM:

- Pin volume and network names (name:) so compose and the cgroup-v2 run.sh
  wrapper share the same objects. Compose otherwise prefixes the project name
  (image_cmk-creds, image_ipa-net), so the run.sh-started freeipa container
  mounted a different cmk-creds volume than the compose-started checkmk wrote
  to — the automation secret never reached IPA and the dev_mon_* integration
  retried forever. run.sh also now labels the network it creates so compose
  adopts it instead of erroring "exists but not created by compose".
- run.sh: mount cmk-creds into freeipa and include checkmk in the "all" target;
  both were missing, so the CheckMK path was never wired up via run.sh.
- Fix both healthchecks: Keycloak has no curl/wget and serves /health on the
  management port 9000 only when KC_HEALTH_ENABLED=true, so the old curl probe
  left it permanently unhealthy — use a bash /dev/tcp probe against 9000.
  CheckMK's /api/1.0/version needs auth (401), so probe the login page instead.
- Advertise a client-routable CheckMK URL (CMK_ADVERTISED_URL) in the
  dev_mon_base description instead of the container-internal 172.30.0.12, which
  enrolled clients cannot reach; falls back to the internal URL when unset.

Amir Alexander Abdelbaki 815c0e57a8 refactor(ansipa): split enforce-policies monolith into modular policies.d/ system
The 1550-line ansipa-enforce-policies.sh is replaced by a slim orchestrator
that sources policy files from policies.d/ — one file per policy type — via
a shared lib/ansipa-policy.sh that consolidates all IPA group discovery into
two queries (one host-show, one group-find) instead of five or more.

New files:
- ansible/lib/ansipa-policy.sh          shared constants, log/warn, _ansipa_discover(),
                                         _smb_parse_cred(), _ansipa_sync_policystore()
- ansible/policies.d/dev_daemon.sh
- ansible/policies.d/dev_timeshift-backup.sh
- ansible/policies.d/dev_security-scan.sh
- ansible/policies.d/dev_no-local-users.sh
- ansible/policies.d/dev_local-sudo.sh
- ansible/policies.d/dev_ssh.sh
- ansible/policies.d/dev_mon.sh         includes usr_mon_logins (same CMK dep)
- ansible/policies.d/usr_admin.sh
- ansible/policies.d/usr_block-binary.sh
- ansible/policies.d/usr_prt.sh
- ansible/policies.d/usr_scan-notify.sh
- ansible/policies.d/usr_smb.sh
- ansible/policies.d/usr_policystore.sh NEW: auto-mount ~/policystore for
                                         usr_smb_adm_policystore members

The policies.d/ folder on the FreeIPA container is exposed as an SMB share
(ansipa-policystore) so admins can live-edit policy files without Ansible.
The enforcer syncs from the share before each run; cached local files are
used as fallback when SMB is unreachable.

- ansipa-smb-setup.sh: adds ansipa-policystore share + smb-policystore system
  user + usr_smb_adm_policystore IPA group with auto-generated credential
- deploy-ansipa-policies.yml: deploys lib/ and policies.d/ to enrolled clients;
  adds optional seed_policystore task for bootstrap

Amir Alexander Abdelbaki 0dd7ce3b51 docs(ansipa): document all policies; fix package check for pacman/dpkg
- ansipa-enforce-policies.sh header: add missing dev_ssh_*, usr_smb_r_*,
  usr_smb_rw_*, dev_mon_* (base/malware/timeshift/power), usr_mon_logins
  with concise descriptions matching actual behaviour.  Notes section
  updated with CheckMK setup prerequisite.
- ansipa_packages local check: replace broken rpm||dpkg fallback (wc -l
  always exits 0 so dpkg/pacman branches were never reached) with an
  if/elif/elif that probes for rpm, dpkg, or pacman in order.  Includes
  pacman.log-based recent-packages list for Arch hosts.
- deploy-ansipa-policies.yml prerequisites: add CheckMK and SMB mount notes.
- .env.example: add CheckMK section (CMK_ADMIN_PASSWORD, CMK_SITE_ID).

Amir Alexander Abdelbaki 6bb19cea78 feat(ansipa): integrate CheckMK CE monitoring
Adds full CheckMK CE 2.3 monitoring integration to the ansipa policy
enforcement system. Monitoring is group-driven — adding a host to an
IPA hostgroup installs the relevant agent checks automatically.

New monitoring groups:
  dev_mon_base      — install check-mk-agent, register host in CMK;
                      packages check + built-in CPU/RAM/disk/uptime
  dev_mon_malware   — ClamAV scan results from dev_security-scan log
  dev_mon_timeshift — Timeshift snapshot age (WARN >5d, CRIT >10d)
  dev_mon_power     — CPU package TDP via Intel RAPL or lm-sensors
  usr_mon_logins    — SSH login attempts (success/failed/invalid-user)

Key implementation details:
- ansipa-checkmk-setup.sh: one-time folder/group creation on FreeIPA
  container; reads automation secret from shared cmk-creds volume;
  stores credentials in IPA dev_mon_base description for clients
- ansipa-checkmk.service: starts after IPA first-boot, retries until
  both IPA and CheckMK are ready
- docker-compose.yml: CheckMK container adds port 8000 (agent receiver
  for push mode); command override writes automation.secret to shared
  volume, patches cookie_auth.conf for API access, and polls
  /cmk-creds/push-mode-*.req to configure push-agent hosts in hosts.mk
- ansipa-enforce-policies.sh: local check scripts for all 5 groups;
  cmk-agent-ctl registration + auto push timer when push mode is active
- CheckMK REST API path corrected to /cmk/check_mk/api/1.0/ (not
  /cmk/api/1.0/ which returns 404 in 2.3)
- .gitignore added to prevent accidental commit of .env test creds

Amir Alexander Abdelbaki 76c3c2c1c5 feat(ansipa): add usr_smb_* and dev_ssh_* policies
usr_smb_r_<name> / usr_smb_rw_<name> (user groups):
- Server creates /data/smb-shares/<name>/ with smb-<name> system user,
  setgid directory, and Samba share stanzas [usr-<name>-r/rw] on startup
- Auto-generates credentials and stores them in IPA group descriptions
  (cifs://<host>:<samba-user>:<password>) so no out-of-band secret distribution
- Client mounts //ipa/<share> at ~/‹name› for logged-in members;
  rw membership wins over r when user is in both groups
- Revert: unmounts and rmdir the mount point on group leave

dev_ssh_<userid> (host group):
- Reads IPA user's SSH public keys (ipasshpubkey / --all output)
- Writes them into /home/<userid>/.ssh/authorized_keys in an
  ansipa-managed section (preserves manually-added keys)
- Home dir is created if it doesn't exist (user may not have logged in yet)
- Revert: removes only the ansipa-managed section on group leave
- Enables same-key SSH access from any registered device to enrolled hosts

Also: add cifs-utils + openssh-server to Ansible package list

Amir Alexander Abdelbaki 65e859b8f9 fix(ansipa): full end-to-end test + multiple bug fixes
Fixes found during a complete archiso → FreeIPA DC → client enrollment →
ansipa policy deployment test cycle (Rocky 9 client VM, FreeIPA in Docker):

arch-autoinstall.sh:
- Add openssh to pacstrap — was missing, breaking headless/automated installs
- Enable sshd at boot and set PermitRootLogin yes for post-install access

ansipa-install-packages.sh:
- Fix broken uninstall logic: three always-true conditions caused every package
  removal to be silently skipped; replace with a state-file-based approach that
  tracks packages installed by ansipa and removes only those when the IPA group
  disappears

ansipa-enforce-policies.sh:
- Add usr_admin policy: creates /etc/sudoers.d/ansipa-usr-admin granting full
  sudo to the FreeIPA usr_admin user group on every enrolled host; reverted
  when the IPA group is deleted
- Add usr_prt_<printer> policy: auto-adds CUPS printers for FreeIPA user group
  members at login; printer URI stored in IPA group description; per-user ACL;
  reverted when group is deleted or membership ends

deploy-ansipa-policies.yml:
- Document usr_admin and usr_prt_* policies in header comment
- Install cups package on clients (required for printer policy)

FreeIPA container (image/):
- Add docker-env.service: extracts IPA_*/SMB_*/LUKS_*/KEYCLOAK_* env vars from
  /proc/1/environ into /etc/container.env on container start; services read from
  there rather than relying on PassEnvironment (which is lost on container restart)
- Add run.sh: wrapper that starts FreeIPA with --cgroupns host, required on cgroup
  v2 hosts (WSL2, recent Linux) because Docker Compose schema does not expose
  cgroupns_mode; also wires LUKS_KEY_UPLOAD_PASSWORD which the SMB service needs
- Dockerfile: copy + enable docker-env.service; add glibc-langpack-en for locale
- ansipa-smb.service: use EnvironmentFile=/etc/container.env (via docker-env.service)
  instead of PassEnvironment; add docker-env.service dependency
- ipa-first-boot.service: add docker-env.service dependency + EnvironmentFile
- ipa-first-boot.sh: add --skip-mem-check (container has limited cgroup memory
  visibility); remove --no-reverse from non-DNS path (was invalid without DNS)
- docker-compose.yml: add prominent cgroupns note explaining when to use run.sh

Amir Alexander Abdelbaki 5d56984e38 feat(ansipa): store LUKS backup keys on SMB share with KeyAdmin access control
ansipa-smb-setup.sh:
- Adds KeyAdmin Linux group and luks-upload service account (member of
  KeyAdmin) on the IPA container, both persisted across restarts.
- LUKS base dir /data/luks-keys owned root:KeyAdmin, mode 2750 (setgid
  so new files inherit the group).
- New [ansipa-luks-keys] SMB share: valid users = @KeyAdmin, read only,
  write list = luks-upload. Human admins gain read access by being added
  to KeyAdmin: useradd -r -G KeyAdmin <user> && smbpasswd -a <user>.
- LUKS_KEY_UPLOAD_PASSWORD sourced from env / /data/samba/ansipa-smb.env
  alongside the existing SMB_SCAN_PASSWORD.

collect-luks-keys.yml:
- After fetching /_LUKS_BACKUP_KEY from each client, uploads it to the
  ansipa-luks-keys share via smbclient using a temp credentials file
  (no_log, deleted in post_tasks).
- Local staging copy is removed after a successful upload.
- SMB credentials file uses an epoch-stamped path to avoid collisions.

.env.example: documents LUKS_KEY_UPLOAD_PASSWORD.

Amir Alexander Abdelbaki c56c86d57b fix(freeipa): harden container SMB setup and fetch-alerts script
ansipa-smb.service: WantedBy=multi-user.target (was smb.service) so the
  setup service always runs at boot, not only when smb.service pulls it in

docker-compose.yml: add NetBIOS UDP ports 137/138 to match Dockerfile EXPOSE
  and nmb.service being enabled

ansipa-smb-setup.sh:
  - use printf '%q' when writing SMB_SCAN_PASSWORD to ansipa-smb.env so
    passwords with spaces or shell-special chars are correctly quoted
  - always write /etc/cron.d/ansipa-check-scans (remove the [[ ! -f ]] guard)
    since /etc/cron.d is on the ephemeral container layer and is lost on
    container recreation; the service runs on every start anyway

Dockerfile: add -e SMB_SCAN_PASSWORD and -p 445:445 to the quick-test comment

ansipa-fetch-alerts.sh: replace $NEW && log with [[ "$NEW" == true ]] && log
  to avoid set -e ambiguity with the 'false' builtin

Amir Alexander Abdelbaki 11e66dbddd feat(freeipa): scan result reporting, alert notifications, and SMB share
Container (ansipa image):
- Add samba + cronie to Dockerfile; expose ports 445/139
- ansipa-smb-setup.sh: idempotent setup of smbd + scanupload user +
  /data/scan-results/{archive,alerts}/ on every container start
- ansipa-smb.service: runs setup before smb.service on each boot
- ansipa-check-scans.sh: hourly cron on server; analyses archive logs for
  ClamAV/rkhunter/chkrootkit findings and writes <host>/<date>.alert files
- docker-compose.yml: add SMB_SCAN_PASSWORD env var + port mappings
- .env.example: document SMB_SCAN_PASSWORD

Client (policy-security-scan):
- Scan script now uploads log to //ipa-server/ansipa-scans/archive/<host>/
  via smbclient after each run

Client (policy-scan-notify — new policy group):
- ansipa-fetch-alerts.sh: root timer (10 min) downloads alerts from SMB into
  ~/administration/<hostname>/ for each active login session; deletes server
  alert when user removes local file (acknowledgment)
- ansipa-scan-notify.sh: user daemon started via /etc/profile.d/ansipa-notify.sh;
  sends notify-send every 10 min while *.alert files remain in ~/administration/
- deploy-ansipa-policies.yml: installs samba-client, deploys SMB creds file
  (/etc/ansipa-smb.creds, 0600), and deploys both notification scripts

Amir Alexander Abdelbaki f66775ce54 setup: add FreeIPA image builder and Keycloak integration
freeipa-image-builder.sh: TUI chooser that builds a FreeIPA server image
and exports it to four target formats:
  docker      — builds via podman/docker, optional registry push
  lxc         — exports container rootfs as .tar.zst Proxmox CT template,
                 generates pct import instructions
  proxmox-vm  — downloads Rocky/Fedora cloud image, customizes with
                 virt-customize, outputs QCOW2 + cloud-init user-data.yml
  oci-archive — skopeo OCI tarball for air-gapped import

Keycloak TUI option generates the full constellation:
  docker-compose.yml   FreeIPA + Keycloak + PostgreSQL stack
  .env                 pre-filled env template (passwords placeholder)
  keycloak-configure.sh  post-start Keycloak REST API config script

image/Dockerfile: Fedora 41 + freeipa-server-dns + ansible-core,
systemd-enabled container (CMD /sbin/init).

image/ipa-first-boot.{sh,service}: systemd oneshot that runs
ipa-server-install on first container/VM boot from env vars
(IPA_DOMAIN, IPA_ADMIN_PASSWORD, IPA_DM_PASSWORD, and optionals).
ConditionPathExists=!/etc/ipa/default.conf makes it idempotent.

image/keycloak-configure.sh: Keycloak REST API automation that:
  - waits for Keycloak readiness
  - creates a realm
  - wires FreeIPA LDAP user federation (READ_ONLY, vendor=rhds)
  - adds attribute mappers: email, firstName, lastName, uidNumber
  - adds group mapper (IPA groups → Keycloak groups, cn=groups,cn=accounts)
  - triggers an initial full user sync

image/docker-compose.yml: freeipa + postgres + keycloak services on
a private 172.30.0.0/24 bridge; FreeIPA has a fixed IP so Keycloak
can resolve it via extra_hosts.
