TCP 9981

ProtocolTCP
Port9981
LabelsTvheadend HTTP server (web interface)

Synopsis

  • TVHeadend (open-source TV streaming/DVR) uses TCP port 9981 by default for its web interface, HTTP API, and HTTP-based streaming.
  • This is seen in real deployments such as TVHeadend packages on Debian/Ubuntu, Docker images like linuxserver/tvheadend, and on media-center systems (LibreELEC/OSMC) and NAS community packages for Synology/QNAP.
  • Clients and integrations (e.g., TvhProxy for Plex, mobile apps like TVHClient) commonly connect to TVHeadend on 9981; note its companion HTSP protocol uses TCP 9982.
  • Security note: Publicly exposed TVHeadend instances on 9981 have been targeted by Internet scans, and some historical versions had vulnerabilities (e.g., XSS/DoS), so administrators typically restrict or authenticate access.
