mountd(8)mountd(8)NAMEmountd - Services remote NFS compatible mount requests
SYNOPSISmountd [-d] [-i] [-n] [-p port_num] [-r] [-R] [-s] [exportsfile]
OPTIONS
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 reso‐
lution. 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. Forces mountd to bind to the specified
port number, instead of using the random port number 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 veri‐
fication 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.
DESCRIPTION
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 giga‐
bytes. However, they appear as 2 gigabyte partitions when viewed from
NFS clients.
