Hostname Formats211is a space between the hostname and the options, the options apply to the rest of theworld. For example, examine the following lines:/misc/export speedy.example.com(rw,sync)/misc/export speedy.example.com (rw,sync)The first line grants users from speedy.example.com read-write access and denies allother users. The second line grants users from speedy.example.com read-only access(the default) and allows the rest of the world read-write access.Each time you change /etc/exports, you must inform the NFS daemon of the change, or reloadthe configuration file with the following command:/sbin/service nfs reload21.3.2. Hostname FormatsThe host(s) can be in the following forms:• Single machine — A fully qualified domain name (that can be resolved by the server), hostname(that can be resolved by the server), or an IP address.• Series of machines specified with wildcards — Use the * or ? character to specify a string match.Wildcards are not to be used with IP addresses; however, they may accidentally work if reverseDNS lookups fail. When specifying wildcards in fully qualified domain names, dots (.) are notincluded in the wildcard. For example, *.example.com includes one.example.com but does notinclude one.two.example.com.• IP networks — Use a.b.c.d/z, where a.b.c.d is the network and z is the number of bits in thenetmask (for example 192.168.0.0/24). Another acceptable format is a.b.c.d/netmask, wherea.b.c.d is the network and netmask is the netmask (for example, 192.168.100.8/255.255.255.0).• Netgroups — In the format @group-name, where group-name is the NIS netgroup name.21.3.3. Starting and Stopping the ServerOn the server that is exporting NFS file systems, the nfs service must be running.View the status of the NFS daemon with the following command:/sbin/service nfs statusStart the NFS daemon with the following command:/sbin/service nfs startStop the NFS daemon with the following command:/sbin/service nfs stopTo start the nfs service at boot time, use the command:
