System: NetBSD boks.pvv.unit.no 1.0A NetBSD 1.0A (BOKS) #14: Tue Mar 14 23:33:44 MET 1995 root@boks.pvv.unit.no:/usr/src/sys/arch/i386/compile/BOKS i386


>Description:
	amd should have options equivalent to these two options (from
mount_nfs manpage):

     -P      Use a reserved socket port number.  This is useful for mounting
             servers that require clients to use a reserved port number.

     -c      For UDP mount points, do not do a connect(2).  This must be used
             for servers that do not reply to requests from the standard port
             number.

'useful' is a slight understatement, 'must be used' is a better
description.

Some thoughts:
Wouldn't it be just as easy just to have the kernel *always* use a
reserved port number? This would simplify mount_nfs, amd, and the
kernel a bit, but give a small change that mounts would fail (if
all the reserved ports are used).


>How-To-Repeat:
	Try to amd mount filesystems from NFS servers with one of the
above-described properties.

>Fix:
	Please apply the following patches. These are according to
the rest of amd (and, for "noconn", the documentation).
