The --address CLI flag (and NORNICDB_ADDRESS / server.host config key) is plumbed through to the HTTP server correctly but never reaches the Bolt server config. The Bolt listener therefore always binds to the wildcard address (all interfaces), regardless of what the user configures.
On a LAN, this exposes the graph database — with its default admin:password credentials — to any device sharing the network.
nornicdb v1.0.39afe7c9d on main$ nornicdb serve --address 127.0.0.1 --bolt-port 7687 --http-port 7474 ...
Output claims Bolt is on localhost:
Bolt server listening on bolt://localhost:7687
But the actual socket:
$ netstat -an -p tcp | grep 7687
tcp46 0 0 *.7687 *.* LISTEN
$ lsof -iTCP:7687 -sTCP:LISTEN -n -P
nornicdb ... IPv6 ... TCP *:7687 (LISTEN)
HTTP port is correctly bound:
tcp4 127.0.0.1.7474 *.* LISTEN
Reachable from another host on the LAN:
$ nc -z 192.168.x.y 7687
Connection to 192.168.x.y port 7687 [tcp/*] succeeded!
Setting NORNICDB_BOLT_ADDRESS=127.0.0.1 or server.host: "127.0.0.1" in config.yaml has no effect on the Bolt listener.
In pkg/bolt/server.go:774-776:
func (s *Server) ListenAndServe() error {
addr := fmt.Sprintf(":%d", s.config.Port)
listener, err := net.Listen("tcp", addr)
...
}
bolt.Config (line 474) has no Host/Address/Addr field — only Port. The CLI flag --address is stored in a local variable in cmd/nornicdb/main.go:80 and used to format user-facing log output (line 637–644), but is never copied into boltConfig at line 600–609 when Bolt is initialized.
Since ListenAndServe calls net.Listen("tcp", ":7687") with an empty host, Go binds the wildcard socket on all interfaces.
