40 Chapter 2 Inside Mac OS X Server
 Browsing, which allows clients to browse for available servers across subnets
You can set up (and replicate) Primary Domain Controller (PDC) services, which:
 Provide Windows domain authentication from the Windows login window.
 Support Windows roaming profiles on Mac OS X Server.
Mac OS X Server provides unified file locking across AFP and SMB/CIFS protocols,
letting Windows users share files with users on other computers without conflict or
corruption. SMB/CIFS also supports ACLs.
Network File System (NFS) Service
NFS is the protocol used for file services on UNIX computers.
The NFS term for sharing is export. You can export a shared item to a set of client
computers or to “World.” Exporting an NFS volume to World means that anyone who
can access your server can also access that volume.
NFS doesn’t support name/password authentication. It relies on client IP addresses to
authenticate users and on client enforcement of permissions, not a secure approach in
most networks. Therefore, use NFS only if you’re on a local area network (LAN) with
trusted client computers, or if you’re in an environment that can’t use Apple file sharing
or Windows file sharing. If you have Internet access and plan to export to World, your
server should be behind a firewall.
You can reshare NFS mounts using AFP, Windows, and FTP so that users can access NFS
volumes in a more restricted fashion.
File Transfer Protocol (FTP)
FTP allows computers to transfer files over the Internet. Clients using any operating
system that supports FTP can connect to your FTP file server and download files,
depending on the permissions you set. Most Internet browsers and a number of
freeware applications can be used to access your FTP server.
FTP service in Mac OS X Server supports Kerberos v5 authentication and, for most FTP
clients, resumption of interrupted FTP file transfers. Mac OS X Server also supports
dynamic file conversion, allowing users to request compressed or decompressed
versions of information on the server.
Mac OS X Server supports anonymous FTP and by default prevents anonymous FTP
users from deleting files, renaming files, overwriting files, and changing file
permissions. Explicit action must be taken by an administrator to allow uploads from
anonymous FTP users, and then only into a specific share point.
