>Release: FreeBSD 2.2-STABLE i386
>Environment:
2.2 stable circa Sep 8
>Description:
Man page for mount_nfs says -P option fprces prov port to
be used, for probably some security reasons, making me believe
that no -P options means no priv port, but in fact in always
takes priv port anyeyas.
It would not be a problem (or rather doc problem), but together
with kern/4327 it makes using Solaris 2.5 server impossible.
>How-To-Repeat:
Just mount any NFS file system on FreeBSD 2.2 stable as client
and look at netstat to confirm that indeed the port on the client
side is always under 1024 regardless of -P option.
>Fix:
Following just changes default:
RCS file: /spare/ncvs/src/sbin/mount_nfs/mount_nfs.c,v
retrieving revision 1.14.2.2
diff -c -r1.14.2.2 mount_nfs.c
