Synopsis

  • Apple iOS WebDriverAgent (used by Appium): runs an HTTP server on TCP 8100 on iOS devices/simulators, typically accessed via USB port forwarding (e.g., iproxy 8100 8100) to drive automated UI tests through REST endpoints.
  • SAP NetWeaver Message Server (HTTP interface): listens on port 81NN (NN = instance number), so systems with instance number 00 use TCP 8100; SAP Web Dispatcher and admin tools query this port for logon groups and instance/cluster information.
  • Security note: Exposed WebDriverAgent on 8100 has been abused in poorly isolated test labs because it lacks authentication, enabling remote control of connected iOS devices.
