NFS Services Administrator's Guide (B.11.31.03) August 2008

Changes to the NFS Server Daemon
The NFS server daemon (nfsd) handles client filesystem requests. By default, nfsd
starts over TCP and UDP for NFSv2 and NFSv3. If NFSv4 is enabled, the nfsd daemon
is started to service all TCP and UDP requests.
If you want to change startup parameters for nfsd, you must login as superuser (root)
and make changes to the /etc/default/nfs file or use the setoncenv command.
The /etc/default/nfs file provides startup parameters for the nfsd daemon and
rpc.lockd daemon. For more information on the /etc/default/nfs file, see
nfs(1M).
The setoncenv command initializes, displays, and removes the value of NFS
configuration variables found in either of the following files:
• /etc/rc.config.d/nfsconf
• /etc/rc.config.d/namesvrs
• /etc/default/autofs
• /etc/default/keyserv
• /etc/default/nfs
• /etc/default/nfslogd
• /etc/pcnfsd.conf
For more information on the setoncenv command, see setoncenv(1M).
Configuring and Using NFS Netgroups
This section describes how to create and use NFS netgroups to restrict NFS access to
your system. It describes the following tasks:
• “Creating Netgroups in the /etc/netgroup File”
• “Using Netgroups in Configuration Files”
Creating Netgroups in the /etc/netgroup File
To create netgroups in the /etc/netgroup file, follow these steps:
1. If you are using the local /etc/netgroup file or the NIS netgroup map for
netgroups, add entries with the following syntax to the /etc/netgroup file.
netgroup_name (host, user, NIS_domain) (host, user, NIS_domain) ...
If you are using NIS, edit the /etc/netgroup file only on the NIS master server.
2. If you are using NIS to manage your netgroups database, enter the following
commands on the NIS master server to generate the netgroup,
netgroup.byhost, and netgroup.byuser maps from the /etc/netgroup
file, and push the generated maps to the NIS slave servers:
cd /var/yp
/usr/ccs/bin/make netgroup
