Type: Technical
Reported by: anatoly techtonik <[email-masked]>

Section: GLOBAL

Original Text
-------------
This document describes the Open Network Computing (ONC) Remote
Procedure Call (RPC) version 2 protocol as it is currently deployed
and accepted.

Corrected Text
--------------

Notes
-----
The document doesn't describe UDP and TCP port number 111, which is used to make initial connection for RCP services discovery and port mapping. Port mapping is an essential part of protocol without which ONC RPC services can't work.

RFC doesn't describe 111 is hardcoded number or can be changed. Doesn't say that servers typically listen on both UDP and TCP 111 (Linux nfs-kernel-server).
