TCP 2020
Synopsis
- 2020/tcp is the IANA-registered “xinupageserver,” used by the Xinu operating system’s remote page server.
- It appears in practice on academic/research Xinu deployments (e.g., Purdue University’s Xinu lab), where embedded targets use TCP 2020 to communicate with a Unix host for demand paging.
- No widely adopted commercial software is known to default to TCP/2020.
