The hub waited only 5s (the request manager default) for stats over
WebSocket and closed the connection on any error. On hosts where
`zpool list` stalls (seen on Proxmox, up to its 10s timeout), collection
exceeded that limit, so the hub sent a close (code 1000) and the agent
reconnected. The refresh ran every other cycle, which caused a
disconnect roughly every 2 minutes.
Hub:
- Wait up to 30s for WebSocket stats responses.
- Keep the connection open when a stats request times out; only close
it (and fall back to SSH) for other errors.
Agent:
- After the first collection, refresh `zpool list` pool stats and
`zfs list` dataset usage in the background and serve cached values
meanwhile, so a hung utility cannot delay the stats response.
With TRUSTED_AUTH_HEADER set, the hub authenticates a request from the
header alone, whichever address it comes from. That is right when every
request passes through the reverse proxy, and not when the hub can also
be reached directly: anyone who can reach it sets the header themselves.
TRUSTED_PROXY_IPS takes a comma-separated list of IPs or CIDR ranges.
When set, the header is only honored on requests whose peer address is
in the list; other requests fall through to the normal authentication.
When unset, nothing changes.
The check uses the connection's RemoteAddr, not a forwarded header, so
the list names the proxy itself. IPv4-mapped IPv6 entries are treated as
IPv4. Entries that do not parse are skipped with a warning on the
console; a list with no valid entry trusts nobody, so a typo narrows the
allowlist instead of widening it.
Listen for prefers-color-scheme changes in ThemeProvider and expose resolvedTheme so the login border color follows the active theme without a hard refresh.
- Validate resolved IPs immediately before connecting.
- Guard Shoutrrr requests during initialization and delivery.
- Require admins for services without HTTP client support.
- Test DNS rebinding, redirects, internal hosts, and authorization.
- Upgrade Shoutrrr to 0.20.0 to support custom dialcontext
- synchronize realtime subscription state
- prevent overlapping fetches per system
- add realtime worker lifecycle tests
- reject subscriptions without system access
- test access revocation and shared-system permissions
