TCP 6800
Synopsis
- aria2 uses TCP port 6800 by default for its RPC interface (JSON-RPC/XML-RPC) to control the aria2 download daemon.
- Real-world clients that connect to aria2 on 6800 include AriaNg and webui-aria2 (web front-ends), as well as desktop download managers like uGet and Persepolis.
- Many NAS/community packages that bundle aria2 (e.g., on Synology or QNAP) also use the 6800 RPC port when configured for remote control.
- The Ceph distributed storage system commonly uses the 6800–7300 range; OSD (and sometimes MDS) daemons often bind to TCP 6800 for messenger v1 traffic in real deployments.
- Security note: Exposed aria2 RPC services on 6800 have been abused by attackers when left unauthenticated, allowing remote parties to hijack downloads or write files; use an RPC secret and restrict access.
