- run-command.sh: services / stop <name> / start <name> for app and infra
stacks (not caddy, hetzner-admin, status). Stopped names go to
status/stopped.txt (gitignored).
- status: a stopped service that does not respond is STOPPED (gray),
excluded from uptime and DOWN alerts. If it responds it is UP as usual.
- Infra deploy.sh skips stopped stacks; app repo pushes clear the flag.
- claude-code@.service: Restart=on-failure, and restart-sessions.sh restarts
one unit at a time, to avoid the tmux "server exited unexpectedly" race.

install.sh overwrote /root/.ssh/authorized_keys with server/authorized_keys,
dropping the restricted hetzner-admin key and making every admin UI
command fail with an SSH authentication error. Append it on install.

Replace Basic auth with a session-cookie login page. After password
login, register a passkey from the bottom of the page; later logins
can use it. Passkeys are stored in hetzner-admin/data/ (gitignored).

Drop Uptime Kuma (uptime.yyamashita.com) and the hetzner-admin /status
page; status-app + ntfy alerts is the single status site. hetzner-admin
now just links to it.

- status/: lightweight status checker (status.yyamashita.com, /api/status)
with ntfy DOWN/recovered alerts after consecutive failures
- uptime-kuma/: Uptime Kuma at uptime.yyamashita.com
- hetzner-admin: authenticated /status page (status-app results + docker ps -a)
- ntfy/: self-hosted ntfy at ntfy.yyamashita.com (deny-all auth, install.sh
creates admin user and status-app token)
- Caddyfile, DNS, post-receive hook, tests/check.sh, docs updated
- license-slot-checker: add to repos.txt, hook, and Claude sessions

The `-` prefix tells systemd to ignore the exit code of tmux kill-session,
so restart succeeds even when the claude process has crashed and the session
no longer exists.

Change button layout from inline (margin-right) to block (margin-bottom)
for better mobile/readability on hetzner-admin web interface.

- Caddyfile: extract repeated header blocks into (noindex)/(crawler_bypass)
snippets (adapted JSON verified byte-identical to previous config)
- CLAUDE.md: add mosquitone-admin/microblog to repos table; document that
proxy auth is disabled (PROXY_NO_AUTH=1) with JP-only IP filter instead
- Deploy.md/caddy/README.md: reflect all-service deploy and forward proxy
- tests/check.sh: shell/python syntax, repos.txt<->hooks<->sessions.txt
consistency, app.py COMMANDS vs run-command.sh whitelist, secrets check

Downloads jp-aggregated.zone from ipdeny.com at container startup (no
account required). Falls back to open access if download fails.
Removed caddy-maxmind-geoip module (no longer needed).

Uses caddy-maxmind-geoip module to restrict proxy access to JP IPs.
DB file (GeoLite2-Country.mmdb) must be placed manually on the server.
Filter is inactive when DB file is absent, allowing safe rollout.

Caddy's default directive ordering places redir before forward_proxy,
causing HTTP proxy requests to be redirected to HTTPS instead of being
forwarded. Changing order to forward_proxy before redir fixes this.

The forward_proxy site block must catch all hosts on port 80 because
proxy clients send Host: <target> not Host: proxy.yyamashita.com.
Non-proxy requests fall through to the redir for HTTPS upgrade.

Add PROXY_NO_AUTH env var support to entrypoint.sh to skip basicauth
generation. Set to 1 in docker-compose.yml to allow unauthenticated access.
Revert by removing the environment block from docker-compose.yml.

Replace standalone Squid container with caddy-forwardproxy plugin so the
proxy shares Caddy's existing ports and TLS. HTTP on :80 and HTTPS on :443.
Auth is read from the same vpn/users.conf at Caddy startup via entrypoint.sh.
DNS: add proxy to setup-route53.py WEB_SUBDOMAINS.

- proxy/: Squid container with HTTPS port, Basic auth from vpn/users.conf
- caddy/Caddyfile: add proxy.yyamashita.com block (RSA cert for compat)
- git/hooks: add proxy/deploy.sh to post-receive hook
- CLAUDE.md: document proxy setup and client config

Android 12 IKEv2 may handle IKE-level fragments better than
IP-level fragmentation. iOS was failing with IKE fragmentation
previously (ECDSA cert era) — test if RSA cert + IKE fragmentation
now works for both platforms.

strongSwan skips self-signed root CAs from CERT payloads by default.
Setting cacerts = chain-3.crt in the local section forces it to include
ISRG Root X1 explicitly so Android 12 can complete trust chain validation.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Android 12 native IKEv2 requires the presented cert chain to include
a cert that is directly in the device trust store. Fetch the issuer
root CA (ISRG Root X1) via AIA from the last intermediate cert and
append it to server-chain.crt so strongSwan sends 4 CERT payloads:
Leaf + YR1 + Root YR + ISRG Root X1 (trusted on all Android versions).

install.sh and renew-cert.sh had identical cert fetch/split code.
install.sh now delegates to renew-cert.sh, which in turn calls deploy.sh.
Flow: install.sh → renew-cert.sh → deploy.sh

Both hetzner-admin and vpn install.sh were calling docker compose
directly instead of going through their own deploy.sh, unlike mail
which already followed the correct pattern.

ECDSA chain (YE1→Root YE→ISRG Root X2) is not trusted by iOS IKEv2.
RSA chain (Leaf→R10→ISRG Root X1) is universally trusted.

iOS IKEv2 does not look up intermediates from the system trust store
(unlike TLS/HTTPS). Send all 3 certs: YE1 + Root YE + cross-signed
ISRG Root X2, so iOS can build the full chain through to ISRG Root X1.

iOS may have a bug where it advertises N(FRAG_SUP) but fails to reassemble
IKE fragments in IKE_AUTH responses. Switching to fragmentation=no forces
the large IKE_AUTH response to be sent as a single UDP packet with IP-level
fragmentation, which iOS's standard IP stack handles correctly.

iOS 14+ and Android 11+ have ISRG Root X2 in their trust store.
Sending the cross-signed ISRG Root X2 alongside the trusted
self-signed version can confuse the cert path-building algorithm.
Chain: leaf -> YE1 -> Root YE -> [ISRG Root X2 from trust store]
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
|

Caddy's cert chain contains 4 certs:
1. leaf (signed by YE1)
2. YE1 (signed by Root YE)
3. Root YE (cross-signed by ISRG Root X2)
4. ISRG Root X2 (cross-signed by ISRG Root X1)
iOS/Android trust ISRG Root X1 but not Root YE directly.
The full cross-signed chain must be sent in IKE_AUTH.
strongSwan only reads the first cert from a multi-cert PEM file,
so entrypoint.sh now splits server-chain.crt into individual files
in x509ca/ before starting charon.

iOS/Android VPN stacks don't follow AIA to download intermediate certs,
so YE1 must be sent by the server for cert chain validation.
The original 1236-byte IKE fragment was being dropped mid-path.
Setting fragment_size=512 splits the 1776-byte IKE_AUTH into ~4
fragments of ≤560 bytes each, which should traverse any NAT/router.

YE1 intermediate cert was inflating IKE_AUTH response to 1776 bytes,
causing it to be split into 2 IKE fragments that iOS/Android clients
could not reassemble. Both iOS and Android 12 (Beam Pro) have
Let's Encrypt trust chain in their system store, so the intermediate
cert is not needed.

fragmentation=no caused IP-level fragmentation (1808-byte packets) which is
blocked by mobile networks. Default IKE fragmentation (RFC 7383) works for
iOS/macOS with 2 fragments.
Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
|

fragment_size=0 was interpreted as minimum fragment size (resulting in
4 tiny fragments), not disabled. fragmentation=no in swanctl.conf is
the correct per-connection setting to disable IKE fragmentation entirely.
The server now sends a single large UDP packet; the OS kernel handles
IP fragmentation instead of the IKE layer.

Android (XREAL Beam Pro) fails to reassemble IKE fragments even though
FRAG_SUP is negotiated. IP-level fragmentation (handled by the OS kernel)
works better. Removing the intermediate cert broke macOS/iOS.
This config:
- Sends leaf cert + YE1 intermediate (so any client can verify the chain)
- fragment_size=0 disables IKE fragmentation; the 1776-byte IKE_AUTH
response is sent as one large UDP packet (OS handles IP fragmentation)

Android (XREAL Beam Pro) can't validate the server cert because it lacks
the Let's Encrypt YE1 hierarchy in its system trust store. The fix:
- Serve YE1 cert at https://vpn.yyamashita.com/ca.pem via Caddy
- Android VPN profile: set CA certificate to this downloaded cert
- install.sh / renew-cert.sh now extract and copy YE1 to caddy dir

Android (XREAL Beam Pro) advertises FRAG_SUP but fails to reassemble
IKE fragments. The IKE_AUTH response was 1776 bytes (leaf + YE1 intermediate)
requiring fragmentation into 2 packets. Without x509ca mount, only the leaf
cert is sent (~886 bytes total), fitting in a single packet without fragmentation.
Android fetches the intermediate CA (YE1) via AIA extension before tunnel setup.

- swanctl.conf.tpl: send_cert = always (fix Android cert verification failure)
- docker-compose.yml: mount intermediate CAs to /etc/swanctl/x509ca/
- install.sh: split server.crt into leaf + chain for proper chain distribution
- entrypoint.sh: run charon directly for Docker log visibility,
fix sysctl error handling, fix charon binary path
- strongswan.conf: increase IKE log level to 4 for debugging
