Description Victor Gregorio 2008-03-03 21:09:22 UTC
Description of problem:

The nfs(5) mount page lists udp as the default NFS protocol.
RHEL4 uses tcp as the default NFS protocol.

Version-Release number of selected component (if applicable):

Release: Red Hat Enterprise Linux AS release 4 (Nahant Update 6)
RPM: util-linux-2.12a-17.el4_6.1

How reproducible:

Always

Steps to Reproduce:
1. man 5 nfs
  
Actual results:

tcp            Mount the NFS filesystem using the TCP protocol instead
               of the default UDP protocol.   Many  NFS  servers  only
               support UDP.

udp            Mount  the NFS filesystem using the UDP protocol.  This
               is the default.

Expected results:

Tcp should be listed as the default protocol.

22.2.3. Using TCP

The default transport protocol for NFSv4 is TCP; however, the Red Hat Enterprise
Linux 4 kernel includes support for NFS over UDP. To use NFS over UDP, include
the -o udp option to mount when mounting the NFS-exported file system on the
client system.
