We have a server that users post information via NFS. In order for the to get access their computer has to be in the etc/hosts file. what we want to do is allow the subnet so we don't have to add each PC as they need to post.

3. UNIX for Dummies Questions & Answers
Hi All,
I am to the UNIX world and want to know if I can specify a range of IP addresses instead of having to include one by one on the HOSTS file.
Can I just say
127.20.1.1 to 127.20.1.156 ?
Or the only way is to put one by one along with the machine name next to the IP ?

mountd(8) System Manager's Manual mountd(8)
NAME
mountd - Services remote NFS compatible mount requests
SYNOPSIS
mountd [-d] [-i] [-n] [-s] [exportsfile]
FLAGS
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 flag 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. 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.
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, mountd rereads the exports file. If you are on an NFS client and want to
have changes to the export options on existing NFS client mounts take effect immediately, issue the showmount -e command and specify the
name of the host that is exporting the directory or file system (where the exports file is located). This ensures that NFS is aware of the
export list and options.
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.
FILES
Specifies the command path Contains a list of directories that can be exported Contains a table of local file systems mounted by remote NFS
clients Contains errors logged by the mountd daemon
