.Sh NAME
|
||||
.Nm exports
|
||||
.Nd define remote mount points for NFS mount requests
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
file specifies remote mount points for the NFS
|
||||
mount protocol per the NFS server specification; see
|
||||
.%T "Network File System Protocol Specification" ,
|
||||
RFC 1094, Appendix A and
|
||||
.%T "NFS: Network File System Version 3 Specification" ,
|
||||
RFC 1813, Appendix I.
|
||||
.Pp
|
||||
Each line in the file
|
||||
(other than comment lines that begin with a
|
||||
.Dq # )
|
||||
specifies the mount point(s) and export flags within one local server
|
||||
filesystem for one or more hosts.
|
||||
A host may be specified only once for each local filesystem on the
|
||||
server and there may be only one default entry for each server
|
||||
filesystem that applies to all other hosts.
|
||||
The latter exports the filesystem to the
|
||||
.Dq world
|
||||
and should
|
||||
be used only when the filesystem contains public information.
|
||||
.Pp
|
||||
In a mount entry,
|
||||
the first field(s) specify the directory path(s) within a server filesystem
|
||||
that can be mounted on by the corresponding client(s).
|
||||
There are two forms of this specification.
|
||||
The first is to list all mount points as absolute
|
||||
directory paths separated by whitespace.
|
||||
The second is to specify the pathname of the root of the filesystem
|
||||
followed by the
|
||||
.Fl alldirs
|
||||
flag;
|
||||
this form allows the host(s) to mount at any point within the filesystem,
|
||||
including regular files.
|
||||
The pathnames must not have any symbolic links in them and should not have
|
||||
any
|
||||
.Dq \&.
|
||||
or
|
||||
.Dq \&.\&.
|
||||
components.
|
||||
Mount points for a filesystem may appear on multiple lines each with
|
||||
different sets of hosts and export options.
|
||||
.Pp
|
||||
The second component of a line specifies how the filesystem is to be
|
||||
exported to the host set.
|
||||
The option flags specify whether the filesystem
|
||||
is exported read-only or read-write and how the client UID is mapped to
|
||||
user credentials on the server.
|
||||
.Pp
|
||||
Export options are specified as follows:
|
||||
.Pp
|
||||
.Sm off
|
||||
.Fl maproot No = Ar user
|
||||
.Sm on
|
||||
The credential of the specified user is used for remote access by root.
|
||||
The credential includes all the groups to which the user is a member
|
||||
on the local machine (see
|
||||
.Xr id 1 ) .
|
||||
The
|
||||
.Ar user
|
||||
may be specified by name or number.
|
||||
.Pp
|
||||
.Sm off
|
||||
.Fl maproot No = Ar user:group1:group2:...
|
||||
.Sm on
|
||||
The colon separated list is used to specify the precise credential
|
||||
to be used for remote access by root.
|
||||
The elements of the list may be either names or numbers.
|
||||
Note that user: should be used to distinguish a credential containing
|
||||
no groups from a complete credential for that user.
|
||||
.Pp
|
||||
.Sm off
|
||||
.Fl mapall No = Ar user
|
||||
.Sm on
|
||||
or
|
||||
.Sm off
|
||||
.Fl mapall No = Ar user:group1:group2:...
|
||||
.Sm on
|
||||
Specifies a mapping for all client UIDs (including root)
|
||||
using the same semantics as
|
||||
.Fl maproot .
|
||||
.Pp
|
||||
The option
|
||||
.Fl r
|
||||
is a synonym for
|
||||
.Fl maproot
|
||||
in an effort to be backward compatible with older export file formats.
|
||||
.Pp
|
||||
In the absence of
|
||||
.Fl maproot
|
||||
and
|
||||
.Fl mapall
|
||||
options, remote accesses by root will result in using a credential of -2:-2.
|
||||
All other users will be mapped to their remote credential.
|
||||
If a
|
||||
.Fl maproot
|
||||
option is given,
|
||||
remote access by root will be mapped to that credential instead of -2:-2.
|
||||
If a
|
||||
.Fl mapall
|
||||
option is given,
|
||||
all users (including root) will be mapped to that credential in
|
||||
place of their own.
|
||||
.Pp
|
||||
The
|
||||
.Fl ro
|
||||
option specifies that the filesystem should be exported read-only
|
||||
(default read/write).
|
||||
The option
|
||||
.Fl o
|
||||
is a synonym for
|
||||
.Fl ro
|
||||
in an effort to be backward compatible with older export file formats.
|
||||
.Pp
|
||||
The third component of a line specifies the host set to which the line applies.
|
||||
The set may be specified in three ways.
|
||||
The first way is to list the host name(s) separated by whitespace.
|
||||
(Standard internet
|
||||
.Dq dot
|
||||
addresses may be used in place of names.)
|
||||
The second way is to specify a
|
||||
.Dq netgroup
|
||||
as defined in the netgroup file (see
|
||||
.Xr netgroup 5 ) .
|
||||
The third way is to specify an internet subnetwork using a network and
|
||||
network mask that is defined as the set of all hosts with addresses within
|
||||
the subnetwork.
|
||||
This latter approach requires less overhead within the
|
||||
kernel and is recommended for cases where the export line refers to a
|
||||
large number of clients within an administrative subnet.
|
||||
.Pp
|
||||
The first two cases are specified by simply listing the name(s) separated
|
||||
by whitespace.
|
||||
All names are checked to see if they are
|
||||
.Dq netgroup
|
||||
names
|
||||
first and are assumed to be hostnames otherwise.
|
||||
Using the full domain specification for a hostname can normally
|
||||
circumvent the problem of a host that has the same name as a netgroup.
|
||||
The third case is specified by the flag
|
||||
.Sm off
|
||||
.Fl network No = Ar netname
|
||||
.Sm on
|
||||
and optionally
|
||||
.Sm off
|
||||
.Fl mask No = Ar netmask .
|
||||
.Sm on
|
||||
If the mask is not specified, it will default to the mask for that network
|
||||
class (A, B or C; see
|
||||
.Xr inet_addr 3 ) .
|
||||
.Pp
|
||||
For example:
|
||||
.Bd -literal -offset indent
|
||||
/usr /usr/local -maproot=0:10 friends
|
||||
/usr -maproot=daemon grumpy.cis.uoguelph.ca 131.104.48.16
|
||||
/usr -ro -mapall=nobody
|
||||
/u -maproot=bin: -network=131.104.48 -mask=255.255.255.0
|
||||
/u2 -maproot=root friends
|
||||
/u2 -alldirs -network=cis-net -mask=cis-mask
|
||||
.Ed
|
||||
.Pp
|
||||
Given that
|
||||
.Pa /usr ,
|
||||
.Pa /u
|
||||
and
|
||||
.Pa /u2
|
||||
are
|
||||
local filesystem mount points, the above example specifies the following:
|
||||
.Pa /usr
|
||||
is exported to hosts
|
||||
.Em friends
|
||||
where
|
||||
.Em friends
|
||||
is specified in the netgroup file
|
||||
with users mapped to their remote credentials and
|
||||
root mapped to UID 0 and GID 10.
|
||||
It is exported read-write and the hosts in
|
||||
.Dq friends
|
||||
can mount either
|
||||
.Pa /usr
|
||||
or
|
||||
.Pa /usr/local .
|
||||
It is exported to
|
||||
.Em 131.104.48.16
|
||||
and
|
||||
.Em grumpy.cis.uoguelph.ca
|
||||
with users mapped to their remote credentials and
|
||||
root mapped to the user and groups associated with
|
||||
.Dq daemon ;
|
||||
it is exported to the rest of the world as read-only with
|
||||
all users mapped to the user and groups associated with
|
||||
.Dq nobody .
|
||||
.Pp
|
||||
.Pa /u
|
||||
is exported to all hosts on the subnetwork
|
||||
.Em 131.104.48
|
||||
with root mapped to the UID for
|
||||
.Dq bin
|
||||
and with no group access.
|
||||
.Pp
|
||||
.Pa /u2
|
||||
is exported to the hosts in
|
||||
.Dq friends
|
||||
with root mapped to UID and groups
|
||||
associated with
|
||||
.Dq root ;
|
||||
it is exported to all hosts on network
|
||||
.Dq cis-net
|
||||
allowing mounts at any
|
||||
directory within /u2.

|
||||
.Sh BUGS
|
||||
The export options are tied to the local mount points in the kernel and
|
||||
must be non-contradictory for any exported subdirectory of the local
|
||||
server mount point.
|
||||
It is recommended that all exported directories within the same server
|
||||
filesystem be specified on adjacent lines going down the tree.
|
||||
You cannot specify a hostname that is also the name of a netgroup.
|
||||
Specifying the full domain specification for a hostname can normally
|
||||
circumvent the problem.
|
||||
.Pp
|
||||
Regarding
|
||||
.Fl alldirs ,
|
||||
because NFS mount filehandles are filesystem wide the
|
||||
.Fl alldirs
|
||||
option applies to exports of the entire filesystem \(em even mount points
|
||||
that are higher up elsewhere in the directory hierarchy.
|
||||
Hence if the server has a filesystem
|
||||
.Pa /export
|
||||
and you wished to export the sub-directory
|
||||
.Bd -literal -offset indent
|
||||
/export/root/client -alldirs client.foo.com
|
||||
.Ed
|
||||
.Pp
|
||||
you must realize that this also allows mounts to be requested
|
||||
against other locations in the
|
||||
.Pa /export
|
||||
filesystem; thus the host client.foo.com is also permitted to
|
||||
mount the directory
|
||||
.Pa /export/root/client2
|
||||
if it exists.

After changing the exports file,

a hangup signal should be sent to the

to get it to reload the export information.

|
||||
.Sh SYNOPSIS
|
||||
.Nm nfsd
|
||||
.Op Fl rtu
|
||||
.Op Fl n Ar num_servers
|
||||
.Sh DESCRIPTION
|
||||
.Nm
|
||||
runs on a server machine to service NFS
|
||||
requests from client machines.
|
||||
At least one
|
||||
.Nm
|
||||
must be running for a machine to operate as a server.
|
||||
.Pp
|
||||
Unless otherwise specified, four servers for UDP
|
||||
transport are started.
|
||||
.Pp
|
||||
The options are as follows:
|
||||
.Bl -tag -width Ds
|
||||
.It Fl n Ar num_servers
|
||||
Specifies how many servers to create (max 20).
|
||||
.It Fl r
|
||||
Register the NFS service with
|
||||
.Xr portmap 8
|
||||
without creating any servers.
|
||||
This option can be used along with the
|
||||
.Fl u
|
||||
or
|
||||
.Fl t
|
||||
options to re-register NFS if the portmap server is restarted.
|
||||
.It Fl t
|
||||
Serve TCP NFS clients.
|
||||
.It Fl u
|
||||
Serve UDP NFS clients.
|
||||
.El
|
||||
.Pp
|
||||
For example,
|
||||
.Dq Li "nfsd -u -t -n 6"
|
||||
serves UDP and TCP transports using six daemons.
|
||||
.Pp
|
||||
A server should run enough daemons to handle
|
||||
the maximum level of concurrency from its clients,
|
||||
typically four to six.
|
||||
.Pp
|
||||
.Nm
|
||||
listens for service requests at the port indicated in the NFS
|
||||
server specification; see RFCs 1094 and 1813.

.Fl N
|
||||
option was specified, statistics will be obtained from the running system
|
||||
by calling

||||
.Xr sysctl 2 .
|
||||
Otherwise the specified core and system will be used to fetch
|
||||
data by means of
