Task 1 — fix Stop/Reload Jail returning 404
Root cause: reload_jail and reload_all sent an empty config stream
(["reload", name, [], []]). In fail2ban's reload protocol the end-of-
reload phase deletes every jail still in reload_state — i.e. every jail
that received no configuration commands. An empty stream means *all*
affected jails are silently removed from the daemon's runtime, causing
everything touching those jails afterwards (including stop) to receive
UnknownJailException → HTTP 404.
Fixes:
- reload_jail: send ["start", name] in the config stream; startJail()
removes the jail from reload_state so the end phase commits instead of
deletes, and un-idles the jail.
- reload_all: fetch current jail list first, build a ["start", name]
entry for every active jail, then send reload --all with that stream.
- stop_jail: made idempotent — if the jail is already gone (not-found
error) the operation silently succeeds (200 OK) rather than returning
404, matching the user expectation that stop = ensure-stopped.
- Router: removed dead JailNotFoundError handler from stop endpoint.
391 tests pass (2 new), ruff clean, mypy clean (pre-existing
config.py error unchanged).
Task 2 — access list simulator
- Docker/simulate_accesses.sh: writes fake HTTP-scan log lines in
custom format (bangui-access: http scan from <IP> ...) to
Docker/logs/access.log so the bangui-access jail detects them.
- fail2ban/filter.d/bangui-access.conf: failregex matching the above.
- fail2ban/jail.d/bangui-access.conf: polling jail on access.log,
same settings as bangui-sim (maxretry=3, bantime=60s).
- .gitignore: whitelist new bangui-access.conf files.
- Docker/fail2ban-dev-config/README.md: added "Testing the Access
List Feature" section with step-by-step instructions and updated
Configuration Reference + Troubleshooting.
The backend container mounted fail2ban-dev-config as an anonymous named
volume, while the fail2ban container used a bind-mount of the same local
directory. The backend's /config was therefore always empty, causing
sqlite3.OperationalError when ban_service attempted to open the path
returned by 'get dbfile' (/config/fail2ban/fail2ban.sqlite3).
Change the backend volume declaration from the named volume reference
to the same bind-mount used by fail2ban:
fail2ban-dev-config:/config:ro → ./fail2ban-dev-config:/config:ro
Also removes the now-unused 'fail2ban-dev-config' named-volume entry.
Affected endpoints (all returned HTTP 500, now return HTTP 200):
GET /api/dashboard/bans
GET /api/dashboard/accesses
GET /api/dashboard/bans/by-country
- Add v7_startTransition and v7_relativeSplatPath future flags to
BrowserRouter to silence React Router deprecation warnings
- Add hidden autocomplete='username' inputs to LoginPage and SetupPage
so password managers and browsers stop warning about missing username
fields in password forms
- Mount fail2ban-dev-config volume into backend container at /config:ro
so ban_service can open the fail2ban SQLite database returned by
'get dbfile'; this fixes the 500 on GET /api/dashboard/bans
- Track compose.debug.yml in git (was previously untracked)
