Configuring and Managing MPE/iX Internet Services (August 2002)

Internet Daemon

inetd Configuration File

Adding New Services to inetd Configuration

There are two steps required to add a new service to the suite of Internet Services offered on your system.

First you enter a line of information for the specific service to the inetd configuration file. Then you have

inetd reread its configuration file, which is sometimes called reconfiguring the Internet daemon. In the

unlikely event that inetd is not running when you edit the configuration file, you will invoke the new

configuration by starting inetd. Starting inetd is explained later in this chapter.

To edit the inetd configuration file, do the following:

1. Open the configuration file with an MPE text editor.

The contents will resemble the following:

######################################################################

# sample inetd configuration file

# For information on how to configure this file refer to the Configuring

# and Managing Internet Services manual

# Note: The entries cannot be preceded by a blank space. Blank lines

# and lines beginning with a pound sign(#) are ignored.

######################################################################

# Internet server configuration database

echo stream tcp nowait MANAGER.SYS internal

echo dgram udp nowait MANAGER.SYS internal

daytime stream tcp nowait MANAGER.SYS internal

daytime dgram udp nowait MANAGER.SYS internal

time stream tcp nowait MANAGER.SYS internal

time dgram udp nowait MANAGER.SYS internal

discard stream tcp nowait MANAGER.SYS internal

discard dgram udp nowait MANAGER.SYS internal

chargen stream tcp nowait MANAGER.SYS internal

chargen dgram udp nowait MANAGER.SYS internal

#telnet stream tcp nowait MANAGER.SYS internal

#bootps dgram udp wait MANAGER.SYS /SYS/NET/BOOTPD bootpd

#tftp dgram udp wait USER.TFTP /SYS/NET/TFTPD tftpd

2. Each of the services that run under inetd must have an entry in the configuration file. For example, the

entry for the tftp program in INETDCNF.NET.SYS looks like this:

tftp dgram udp wait USER.TFTP /SYS/NET/TFTPTD tftpd

For the service that you are installing, check the file to see if it has the correct entry. (Each chapter in the

remainder of this manual has this information. The meaning of the individual fields in an entry are

explained later in this chapter.) If not, enter the line now using the “Editing Tips” section, as a guideline.

NOTE For more information on FTP, refer to Installing and Managing HP ARPA File Transfer

Protocol Network Manager’s Guide or HP ARPA File Transfer Protocol User’s Guide.

3. Save the file and exit the editor program.

4. Signal inetd to reread the configuration file by entering the following command at the CI prompt:

INETD.NET.SYS -c

Or you may enter this command from the POSIX shell:

$/etc/inetd -c
