The version 2 support has been tested (client+server) against FreeBSD-2.0, IRIX 5.3 and FreeBSD-current (using a loopback mount). The version 2 support is stable AFAIK. The version 3 support has been tested with a loopback mount and minimally against an IRIX 5.3 server. It needs more testing and may have problems. I have patched amd to support the new variable length filehandles although it will still only use version 2 of the protocol. Before booting a kernel with these changes, nfs clients will need to at least build and install /usr/sbin/mount_nfs. Servers will need to build and install /usr/sbin/mountd. NFS diskless support is untested. Obtained from: Rick Macklem <rick@snowhite.cis.uoguelph.ca>

.Sh SYNOPSIS
|
|
.Nm /sbin/mountd
|
|
.Op Fl nr
|
|
.Op Ar exportsfile
|
|
.Sh DESCRIPTION
|
|
.Xr Mountd
|
|
is the server for
|
|
.Tn NFS
|
|
mount requests from other client machines.
|
|
.Xr Mountd
|
|
listens for service requests at the port indicated in the
|
|
.Tn NFS
|
|
server specification; see
|
|
.%T "Network File System Protocol Specification" ,
|
|
RFC1094, Appendix A and
|
|
.%T "NFS: Network File System Version 3 Protocol Specification" ,
|
|
Appendix I.
|
|
.Pp
|
|
Options and operands available for
|
|
.Nm mountd :
|
|
.Bl -tag -width Ds
|
|
.It Fl n
|
|
The
|
|
.Fl n
|
|
option allows non-root mount requests to be served.
|
|
This should only be specified if there are clients such as PC's,
|
|
that require it.
|
|
.It Fl r
|
|
The
|
|
.Fl r
|
|
option allows mount RPCs requests for regular files to be served.
|
|
Although this seems to violate the mount protocol specification, some diskless
|
|
workstations do mount requests for their swapfiles and expect them to be
|
|
regular files. Since a regular file cannot be specified in /etc/exports, the
|
|
entire file system that the swapfiles reside in will have to be exported with
|
|
the ``-alldirs'' flag.
|
|
.It Ar exportsfile
|
|
The
|
|
.Ar exportsfile
|
|
argument specifies an alternate location
|
|
for the exports file.
|
|
.El
|
|
.Pp
|
|
When mountd is started,
|
|
it loads the export host addresses and options into the kernel
|
|
using the mount(2) system call.
|
|
After changing the exports file,
|
|
a hangup signal should be sent to the mountd daemon
|
|
to get it to reload the export information.
|
|
After sending the SIGHUP
|
|
(kill -HUP `cat /var/run/mountd.pid`),
|
|
check the syslog output to see if mountd logged any parsing
|
|
errors in the exports file.
|
|
.Pp
|
|
If
|
|
.Nm mountd
|
|
detects that the running kernel does not include
|
|
.Tn NFS
|
|
support, it will attempt to load a loadable kernel module containing
|
|
.Tn NFS
|
|
code, using
|
|
.Xr modload 8
|
|
by way of
|
|
.Xr vfsload 3 .
|
|
If this fails, or no
|
|
.Tn NFS
|
|
LKM was available,
|
|
.Nm mountd
|
|
exits with an error.
