TCP 1234
Synopsis
- Parcel (the web app bundler) runs its development server on TCP port 1234 by default.
- VLC media player is commonly configured to serve HTTP streams on TCP 1234 (e.g., http://host:1234) in many real deployments and official examples.
- FFmpeg frequently uses tcp://host:1234 as the listening URL in practical streaming pipelines (e.g., for mpegts over TCP).
- GStreamer pipelines often use TCP 1234 with tcpserversrc/tcpclientsink in real-world tests and demos.
- Tools like netcat/ncat/socat are frequently run on TCP 1234 for ad-hoc services; attackers and red-teamers also commonly choose 1234 for bind/reverse shells and simple C2 listeners because it’s unprivileged and rarely reserved.
