Two-Minute Drill

Here are some of the key points from the certification objectives in Chapter 10.

Configuring a Network File System (NFS) Server


NFS is the standard for sharing files and printers between Linux and Unix computers.


Key NFS processes are rpc.mountd for mount requests, rpc.rquotad for quota requests, and nfsd for each network share.


NFS shares are configured in /etc/exports and activated with the exportfs -a command.

Client-Side NFS


Clients can make permanent connections for NFS shares through /etc/fstab.


If an NFS server fails, it can "hang" an NFS client. When possible, avoid using NFS on mission-critical computers.


NFS and portmap have security problems. Limit their use when possible to secure internal networks protected by an appropriate firewall.

The File Transfer Protocol and vsFTPd


RHEL includes the vsFTP server. The default configuration allows anonymous and real user access.


You can customize vsFTP through the /etc/vsftpd/vsftpd.conf configuration file. It also uses authentication files in the /etc/vsftpd/ directory: ftpusers, user_list, and chroot_list.

Samba Services


Samba allows Microsoft Windows computers to share files and printers across networks, using the Server Message Block (SMB) protocol on the TCP/IP protocol stack.


Samba includes a client and a server. Variations on the mount -t cifs or /sbin/mount.cifs commands allow you to connect to a Microsoft Windows shared directory.


The main Samba configuration file is /etc/samba/smb.conf. You can configure it in a text editor or a GUI tool such as the Samba Server Configuration tool.


Samba allows you to configure your Linux computer as a member of a Microsoft Windows 9x-style workgroup.


Samba allows you to configure your Linux computer as a Microsoft Windows server. It can also provide Microsoft browsing, WINS, and Domain Controller services, even on an Active Directory network.
