Configuring tftpd
To configure tftpd, you will edit two files: the services file, which lists
the individual services that comprise the suite of Internet Services, and
the inetd configuration file, which informs the Internet daemon about
running tftpd on this system. These tasks are explained in the next
sections.
Editing the Services File
The services file associates official service names and aliases with the
port number and protocol the services use. To enable tftpd, you must
update the services file. Perform the following:
1. Open the services file with an MPE text editor. You may edit the
/etc/services file from the POSIX shell or the SERVICES.NET.SYS
file from MPE/iX, whichever you prefer. Both names should point to
the same file.
2. Verify that the following line exists in the file or add it if it does not:
tftp 69/udp # Trivial File Transfer Protocol
3. If the line already exists in the file and it is preceded by a pound
symbol (#),delete the symbol and any spaces before the service name
to enable the service.
4. Save the file and exit the editor program.
Adding TFTP Service to inetd Configuration
The configuration file for inetd determines which installed Internet
Services are available to users. To add tftpd to your system, you will
need to edit this configuration file, then have inetd re-read the
configuration. To do so:
1. Open the inetd configuration file with a text editor. You may edit
the /etc/inetd.conf file from the POSIX shell or the
INETDCNF.NET.SYS file from MPE/iX, whichever you prefer. Both
names point to the same file.
2. Verify that the following line exists in the file or add it if it does not:
tftp dgram udp wait USER.TFTP /SYS/NET/TFTPD tftpd
3. If the line already exists in the file and it is preceded by a pound
symbol (#),delete the symbol and any spaces before the service name
to enable the service.
4. Save the file and exit the editor program.
