Catch the panel up to the mtg-multi README (v1.14.0):
- Each client can now carry its own 32-hex advertising tag overriding the
inbound-level one. The tag lives on the client (settings JSON is the
source of truth, clients.ad_tag is the UI projection), is rendered into
the fork's [secret-ad-tags] section for active secrets only (mtg rejects
a config whose override names an unknown secret), is pushed per entry
through PUT /secrets, and is part of the reload fingerprint so a tag
edit hot-applies without dropping connections.
- The loopback management API can replace the whole secret set, so every
mtg process now gets a random per-process api-token; the manager sends
it as a bearer token on PUT /secrets and GET /stats and reuses it across
config rewrites, because mtg reads the token only at startup.
- Malformed tags are rejected at every save path and additionally dropped
in InstanceFromInbound: one bad tag would otherwise fail the whole
generated config and take every client of the inbound down with it.
- SyncInbound never copied a re-keyed mtproto secret into the canonical
clients table, so the clients page and subscription links kept serving
the old secret, which mtg then rejects. It is now guarded-copied like
the other credentials.
Replace the upstream 9seconds/mtg sidecar with the dolonet/mtg-multi fork so a single MTProto inbound can serve many per-user secrets. Each panel client is now one named FakeTLS secret in the fork's [secrets] section: clients are first-class (attach/detach, limits, expiry, per-client tg:// links) exactly like every other protocol, mirroring the WireGuard multi-client model. Per-client traffic and online status come from the fork's /stats JSON API (its Prometheus output has no per-user label), fed into the existing email-keyed client_traffics accumulator; an optional throttle caps concurrent connections. A one-time seeder converts each legacy single-secret inbound into a one-client inbound.
The fork ships only linux/darwin amd64/arm64 binaries but is pure Go, so provisioning builds it from source for every supported platform (release.yml, DockerInit.sh) while keeping the panel-expected mtg-<os>-<arch> filename and the 'run' verb, so process.go is untouched. Also fixes a pre-existing update.sh gap that never renamed the mtg binary for armv6/armv7 updates.
