Step 3: Create share points and share them using NFS
Use the Sharing module of Workgroup Manager to specify the share points that you want to
export (share) using NFS. You must explicitly configure a share point to use NFS in order for
NFS users to be able to access the share point. See “Creating Share Points and Setting
Privileges” on page 221, “Sharing (Exporting) Items Using Network File System (NFS)” on
page 224, and “Automounting Share Points” on page 225.
You don’t need to start or stop NFS service; when you define a share point to export, the
service starts automatically. When you delete all exports, the service stops. You can tell if NFS
service is running by looking for the globe on the NFS icon in Server Settings.
Setting Up NFS Service
Configuring NFS Settings
The NFS settings let you set the maximum number of daemons and choose how you want to
serve clients—via TCP, UDP, or both.
To configure NFS settings:
1 In Server Settings, click the File & Print tab.
2 Click NFS and choose Configure NFS.
3 Enter a value in the “Use__server daemons” field to set the maximum number of nfsd
daemons you want to allow at one time.
An nfsd daemon is a server process that runs continuously behind the scenes and processes
reading and writing requests from clients. The more daemons that are available, the more
concurrent clients can be served. Typically, four to six daemons are adequate to handle the
level of concurrent requests.
4 Choose how you want to serve data to your client computers.
Transmission Control Protocol (TCP) separates data into packets (small bits of data sent over
the network using IP) and uses error correction to make sure information is transmitted
properly.
User Datagram Protocol (UDP) doesn’t break data into packets, so it uses fewer system
resources. It’s more scalable than TCP, and a good choice for a heavily used server. Do not
use UDP, however, if remote clients are using the service.
Select both TCP and UDP unless you have a specific performance concern. TCP provides
better performance for clients, and UDP puts a smaller load on the server.
5 Click Save.
