- fix_dup_volumes.py: 4 canonical templates had TWO volumes: keys inside one
service (invalid YAML -> 'mapping key volumes already defined'), which broke
every enable for anti-alchemy/burvesigner/gemas-notes/kode-viewer.
- fjb: ghcr.io base is not anonymously pullable on this host; swapped to the
official httpd:2.4 (its httpd.conf only uses stock modules). Added
onlyBuiltDependencies to package.json (pnpm >=10 blocks esbuild's postinstall).
- xl + kode-viewer: node:20-slim-bookworm is not a real tag; use
node:20-bookworm-slim. gift-voucher: buster -> bookworm.
- prebuild_images.py: build each challenge's shared services-<name> image once
in parallel (passes a placeholder PASSWORD build-arg, since several Dockerfiles
run chpasswd and fail on an empty arg).
- set_enabled.py / sync_all_challenges.py: batch registry flip + runtime apply
that survives panel restarts and reports per-team results.
- Challenge toggle is now async: PATCH returns a job id, the client polls
/api/challenges/jobs/<id> so a multi-minute build no longer blocks the panel.
Added _SYNC_LOCK to serialize concurrent compose rewrites.
Found by testing a real enable/disable cycle (art, fjb, gift-card):
1. compose_gen always swapped build->image, so a never-built challenge
produced 'pull access denied for services-<name>'. Now it only reuses
the image when it exists locally, otherwise keeps build: so
'docker compose up --build' builds it.
2. Canonical templates use 'build: context: .' (written for the shared
services/ tree). In the per-team compose that resolves to the team dir
which has no Dockerfile -> 'failed to read dockerfile'. The renderer
now rewrites the main service's context to ./<name>.
3. Teams created before the XVI/XVII import had no xvi/xvii subpackages
under their local challenges/ dir, so the regenerated receiver main.py
crash-looped on import. gen_receiver_main now mirrors ALL shared
checkers (native + xvi + xvii) into every team receiver on each sync.
4. systemd Environment= keys can't contain hyphens, so
CHALLENGE_PORT_GIFT-CARD was silently dropped. Keys are now
normalized to underscores on both the writer and reader side.
5. Several checkers called 'docker exec' with no timeout; against a
container with accumulated chall.py zombies that blocks forever and
stalls the whole SLA loop. Added mandatory timeouts (Phew, Sheesh,
Carbeat, Poke, Warmup).
Also: enabling a challenge now copies its source tree into each team's
services/ dir (team dirs only held challenges enabled at create_team
time), and the XVII checkers were rewritten to be protocol-aware
(gift-card/gift-voucher are socat TCP, not HTTP) with strict timeouts.
- all 6 Dockerfiles: vim curl wget netcat git python3-pip now installed
- apt-insecure.conf (AllowInsecureRepositories) copied into images so
participants can apt-get install despite expired Ubuntu/Debian GPG keys
- warmup base ubuntu:20.04 (EOL, GPG expired) -> ubuntu:24.04
- installed vim+git live into all 18 running team containers
- team portal target dropdown reloads after login (was empty pre-auth)
- attack log endpoint + A/D submit (attacker vs target) verified e2e
Receivers were child Popen processes of gemastik-panel systemd cgroup;
restarting the panel killed all team receivers (SLA -> 0/6, 401 on
/api/team/N/status proxy). Now each team receiver is a systemd service
(gemastik-receiver-teamN.service) generated by gen_receiver_services.py with
per-team env (ports, containers, COMPOSE_LOCATION, .env). Verified: panel
restart no longer kills receivers; 18/18 SLA stays UP.
- guide link now server-side replaced to /team/<idx>/guide (no /team/0 403)
- _check_team_host() applied to ALL team endpoints (login, info, targets,
status, guide, portal, ssh-ws): host must match team domain; panel/gemastik
host only with admin session. Cross-domain session reuse -> 403.
- host check BEFORE auth on info/targets (no team-existence oracle)
- loading overlay (spinner + text) on start/stop all-team/set; JS util
showLoading/hideLoading
- PORT_BASE 20000->30000: team1=31xxx team2=32xxx; syncthing owns 22000
- create_team replaces build: with image: services-<name> so teams reuse base images (was rebuilding 6 images per team, disk 100%)
- recovery: receiver/main.py was corrupted by bad patch (write_file with read_file format); restored from team1 copy + original GitHub
- docker compose -p teamN: project isolation so team compose doesn't overlap (was showing team1 containers for team2)
- FastAPI app at panel/ proxying receiver API server-side (admin creds stay server-side)
- Login-protected dashboard: SLA status, rotate flag, restart/rollback/activate/deactivate, SSH creds, command history
- Runs as systemd service gemastik-panel.service on :18081
- Published at https://panel.gemastik.imrnes.team via Traefik
- blogpost: python:3.11-slim-bullseye is EOL (apt 404s), switch to bookworm
- utils/bashrc: host port 80 is taken by Traefik/Coolify, preexec posts to :18080
- ignore receiver .venv
