mountd - Services remote NFS compatible mount requests
mountd [-d] [-i] [-n] [-r] [-R] [-s] [exportsfile]
Verifies the Internet addresses of hosts that make mount
and unmount requests. If a client's address cannot be
translated into a host name by the gethostbyaddr() function
and then translated back into the same Internet
address by the gethostbyname() function, the request is
rejected.
This option requires the BIND service for Internet
address resolution. It offers the highest level of
security, especially when combined with the -i
option. Turns on Internet address verification and
domain checking. If you are running the BIND service,
mountd verifies that a host making a mount or
unmount request is in the server's domain. Allows
non-root mount requests to be served. This should
only be specified if there are clients such as PC's
that require it. ULTRIX BSD is allowed non-root
mount requests by default. Use the -n option to
allow non-root mount requests. Verifies the Internet
address of hosts that make mount and unmount
requests. If a client's address cannot be translated
into a host name by the gethostbyaddr() function,
the request is rejected. If you are running
the BIND service, the BIND server is used to translate
the address. If you are not, the /etc/hosts
file is used.
If the -i option is not used and a client's address
cannot be translated, the address is converted to a
string of the form xx.xx.xx.xx. This allows access
to exported file systems that do not specify a list
of allowed hostnames.
The -i option is automatically enabled when either
the -d or the -s option is specified. Listens for
requests on a reserved port only. This is the
default behavior. Enables listening for requests
on an unreserved port. Turns on Internet address
verification and subdomain checking. If you are
running the BIND service, mountd verifies that a
host making a mount or unmount request is in the
server's domain or subdomain.
The mountd daemon is the server for NFS protocol mount
requests from clients. The mountd daemon responds to
requests from remote computer systems to mount directories.
When it receives a SIGHUP signal, the mountd daemon
rereads the exports file.
The optional exportsfile argument specifies an alternate
location for the exports file. /etc/exports is the
default.
Note, NFS Version 2 can export partitions that are greater
than 2 gigabytes. However, they appear as 2 gigabyte partitions
when viewed from NFS clients.
