TCP 8123

ProtocolTCP
Port8123
LabelsPolipo Web proxy

Synopsis

  • ClickHouse uses TCP 8123 by default for its HTTP interface to run SQL queries (e.g., curl http://host:8123).
  • Home Assistant’s web interface listens on TCP 8123 by default for the smart‑home dashboard.
  • Polipo, a lightweight HTTP proxy (historically bundled with Tor setups), defaults to TCP 8123.
  • Security note: Attackers routinely scan port 8123 for exposed Home Assistant and ClickHouse HTTP endpoints; misconfigured instances have been taken over or had data queried, so internet exposure without authentication is risky.
