431/0.067 ms. The precedin g example uses Fedora/RHEL s default packet size of 4096 bytes and shows a fast average packet round-trip time of slightly more than 1 millisecond. Over a modem line, you can expect times of several seconds. If the connection is dealing with other traffic, the time will be longer.

Run the test during a period of heavy traffic. Try increasing timeo to three or four times the average round-trip time (to allow for unusually bad network conditions, as when the connection is made) and see whether performance improves. Remember that the timeo value is given in tenths of a second (100 milliseconds = one-tenth of a second).

. /etc/fstab: Mounts Directory Hierarchies Automatically The /etc/fst ab file (page 490) lists directory hierarchies that the system mounts automatically as it comes up. You can use the options discussed in the preceding section on the command line or in the fstab file. The first example line from fstab mounts grape s /gc1 filesystem on the /grape.

gc1 mount point:. grape:/gc1 /grape.gc1 nfs rsize=8192,wsize=8192 0 0 A mount poin t should be an empty, local directory. (Files in a mount point are hidden when a directory hierarchy is mounted on it.) The type of a filesystem mounted using NFS is always nfs, regardless of its type on the local system.

You can increase the rsize and wsize options to improve performance. Refer to Improving Performance on page 734. The next example from fstab mounts a filesystem from speedy:.

speedy:/export /speedy.export nfs timeo=50,hard 0 0 Because the local system connects to speedy over a slow connection, timeo is increased to 5 seconds (50 tenths of a second). Refer to Timeouts on page 734. In addition, hard is set to make sure that NFS keeps trying to communicate with the server after a major timeout.

Refer to hard/soft on page 734. The final example from fstab shows a remote-mounted home directory. Because speedy is a local server and is connected via a reliable, high-speed connection, timeo is decreased and rsize and wsize are increased substantially:.

speedy:/export/home /home nfs timeo=4,rsize=16384,wsize=16384 0 0 736 22 NFS: Sharing Filesystems Figure 22-2. NFS Server Configuration window Setting Up an NFS Server Prerequisites Install the visual .net Code128 following package: nfs-utils system-config-nfs (optional) Run chkconfig to cause nfs to start when the system enters multiuser mode:. # /sbin/chkconfig nfs on Start nfs:. # /sbin/service nfs start The nfs init script starts mountd, nfsd, and rquotad. RHEL Under RHEL, barcode code 128 for .NET the portmap daemon (part of the portmap package; refer to RPC Network Services on page 391) must be running to enable reliable file locking..

Notes SELinux When SELinux is set to use a targeted policy, NFS is protected by SELinux. You can disable this protection if necessary. For more information refer to Setting the Targeted Policy with system-config-selinux on page 416.

If the system is running a firewall, you generally need to open TCP port 111 for rpcbind (FEDORA) or portmap (RHEL), TCP ports 1013 and 1016 for mountd, and TCP port 2049 for nfs. If these ports do not allow NFS access, use rpcinfo p (page 443) to determine the TCP ports that the local server uses for these services and then open those ports. Using the Firewall Configuration window Other Ports tab (page 825), open the necessary ports.

For more general information, see 25, which details iptables.. Firewall Setting Up an NFS Server 737 Figure 22-3. Edit NFS Share window JumpStart II: Configuring an NFS Server Using system-config-nfs To display t he NFS Server Configuration window (Figure 22-2), enter the command system-config-nfs or select Main Menu: System Administration [Server Settings ]NFS. From this window you can generate an /etc/exports file, which is almost all there is to setting up an NFS server. If the system is running a firewall, see Notes in the preceding section.

The system-config-nfs utility allows you to specify which directory hierarchies are shared and how they are shared using NFS. Each exported hierarchy is called a share. To add a share, click Add on the toolbar.

To modify a share, highlight the share and click Properties on the toolbar. Clicking Add displays the Add NFS Share window, while clicking Properties displays the Edit NFS Share window. These windows are identical except for their titles.

The Add/Edit NFS Share window has three tabs: Basic, General Options, and User Access. On the Basic tab (Figure 22-3) you can specify the pathname of the root of the shared directory hierarchy, the names or IP addresses of the systems (hosts) that the hierarchy will be shared with, and whether users from the specified systems will be able to write to the shared files. The selections in the other two tabs correspond to options that you can specify in the /etc/exports file.

Following is a list of the check box descriptions in these tabs and the option each corresponds to:.
