NFSD Firewall and SELinux Configuration

NFS is one of the many Red Hat services that can take advantage of TCP Wrappers as well as firewall rules for security. We don’t use TCP Wrappers here, but should you run into trouble on the exam with the NFS service not working, don’t forget to check to see whether anything is being filtered by TCP Wrappers. Because you are using NFS version 4 here, you need to create only a single firewall rule.

Samba Server Configuration

Samba File Sharing

Samba is the file-sharing protocol used by the Microsoft Windows operating system. Because some network environments include more than one operating system, Red Hat Enterprise Linux provides a way to use alternative file-sharing methods. If only sharing between Linux and other UNIX variants, it is recommended that NFS be used instead. For additional information on Samba, refer to the /usr/share/doc/samba-<version>/ directory.

Connecting & Mounting to the NFS Share Folders

Connecting to the NFS Share Folders

There are three ways to mount an NFS export on a client system, assuming the server has given the client permission to do so:

1. Use the mount command along with the server name, exported directory, and local mount point.

2. Add the export to /etc/fstab so it is automatically mounted at boot time or is Available to be mounted.

3. Use the autofs service to mount the share when a user attempts to access it from a client.
