Working with File Services	9

In this chapter you will find commands you can use to create share points and manage file services.

Mac OS X Server allows you to set up central network storage that is accessible to clients throughout your organization. Using native protocols, it delivers file services to heterogeneous clients on your network: Apple Filing Protocol (AFP) for Mac, Network File System (NFS) for UNIX and Linux, Server Message Block/Common Internet File System (SMB/CIFS) for Windows, as well as WebDAV and FTP for Internet clients. This chapter covers the commands that are used to configure and manage these file services.

Managing Share Points

A share point is a folder, hard disk, hard disk partition, CD, or DVD that users can access over the network to share information. Users with access privileges, which are assigned, view share points as mounted volumes.

Mac OS X Server supports Microsoft Windows file sharing of any defined share point, not just Shared and Public folders in a user’s home folder. It also supports Windows Internet Naming Service (WINS), which allows Windows clients across multiple subnets to perform name/address resolution.

You can use the sharing tool to list, create, and modify share points. See the sharing man page for more information.
