The RPM packaged versions for an Internet server include the startup script for that server. Installing the RPM package installs the script in the /etc/rc.d/init.d directory and creates its appropriate links in the runlevel directories, such as /etc/rc.h/rc3.d. If you decide, instead, to create the server using its source code files, you can then manually install the startup script. If no startup script exists, you first make a copy of the httpd script-renaming it-and then edit the copy to replace all references to httpd with the name of the server daemon program. Then, place the copy of the script in the /etc/rc.d/ init.d directory and make a symbolic link to it the /etc/rc.d/rc3.d directory. Or you could use the System V Init Editor to create the link in the /etc/rc.d/rc3.d directory. Have the editor scan the init.d directory by selecting Re-scan from the File menu, click the entry in the Available listing, click the Add button, and then select the Runlevel and Start options in the Add window. When you start your system now, the new server is automatically started up, running concurrently and waiting for requests.

If your system averages only a few requests for a specific service, you don't need the server for that service running all the time. You only need it when a remote user is accessing its service. The Extended Internet Services Daemon (xinetd) manages Internet servers, invoking them only when your system receives a request for their services. xinetd checks continuously for any requests by remote users for a particular Internet service; when it receives a request, it then starts the appropriate server daemon. The xinetd program is designed to be a replacement for inetd, providing security enhancements, logging support, and even user notifications. For example, with xinetd you can send banner notices to users when they are not able to access a service, telling them why. xinetd security capabilities can be used to prevent denial-of-service attacks, limiting remote hosts' simultaneous connections or restricting the rate of incoming connections. xinetd also incorporates TCP, providing TCP security without the need to invoke the tcpd daemon.

Furthermore, you do not have to have a service listed in the /etc/services file. xinetd can be set up to start any kind of special-purpose server. The Red Hat Linux versions 7.0 and up use xinetd. Many older Linux systems may still be using inetd. You can start, stop, and restart xinetd using its startup script in the /etc/rc.d/init.d directory, as shown here:

On Red Hat, you can also turn on and off particular xinetd services with chkconfig, as described earlier. Use the on and off options to enable or disable a service. chkconfig will edit the disable option for the service, changing its value to "yes" for off and "no" for on. For example, to enable the swat server, you could enter:

The xinetd.conf file is the configuration file for xinetd. Entries in it define different servers to be activated when requested along with any options and security precautions. An entry consists of a block of attributes defined for different features, such as the name of the server program, the protocol used, and security restrictions. Each block for an Internet service such as a server is preceded by the keyword service and the name by which you want to identify the service. A pair of braces encloses the block of attributes. Each attribute entry begins with the attribute name followed by an assignment operator such as = and then the value or values assigned. A special block specified by the keyword default contains default attributes for services. The syntax is shown here:

Most attributes take a single value for which you use the standard assignment operator, =. Some attributes can take a list of values. You can assign values with the = operator, but you can also add or remove items from these lists with the =+ and =- operators. Use the =+ to add values and =- to remove values. You often use the =+ and =- operators to add values to attributes that may have an initial value assigned in the default block. Attributes are listed in Table 22-3. Certain attributes are required for a service. These include socket_type and wait. socket_type can be stream for stream-based service, dgram for datagram-based service, raw for service that requires direct access, and seqpacket service for sequential datagram transmission. The wait attribute can have a yes or no value to specify if the server is single-threaded (yes) or multithreaded (no). If yes, then xinetd will wait, calling the server initially and letting that server handle further requests until the server stops. If the value is no (multithreaded), xinetd will continue to handle new requests for the server, generating new server processes to handle them. For a standard Internet service, you would also need to provide the user (user ID for the service), the server (name of the server program), and the protocol (protocol used by the server). With server_arguments, you can also list any arguments you want passed to the server program (this does not include the
